    FIELD OF THE INVENTION The present invention relates to an apparatus and a method for supplying external heat energy to an air stream in an air treatment device in the first place to be able to heat the supply air to, for example, a local, to desired temperature. , regardless of outdoor temperature. The air treatment device comprises an air treatment unit with a heat theater winner and also a heat pump, Pada for utilizing energy from the exhaust air from the room and 'NeffOra this to the supply air when heating the supply air is needed. In addition to the recovery of energy via the heat theater winner and the extraction of energy from the exhaust air with the help of the heat pump, an addition of external energy may be needed to cope with all operating cases in a plant, whereupon an additional heater is also located in the plant.
    Background of the Invention It is an option in air treatment technology to provide an air treatment device with some form of heat theater extraction equipment on various sails to reduce the heating costs for heating cold outdoor air to hot supply air in a plant. Common variants are air-based solutions such as rotary heat theater winners and cross-flow heat theater winners. Furthermore, there are also liquid-connected solutions where the flake form of liquid circulates between the hot and the cold side for absorbing heat from the exhaust air and releasing heat to the supply air.
    To further utilize the energy in the exhaust air, heat pump solutions (Heat Pumps) are also used, where a so-called direct expansion battery - the DX battery in - is placed in the supply air, in the air flow direction after the heat theater winner, and a DX battery is placed in the exhaust air. in the exhaust air after the heat exchanger, ie the air to be released into the open air. In the case of heat, the DX battery placed in the exhaust air is a precursor, while the DX battery in the supply air is a condenser. The DX batteries usually consist of a number of copper tubes with aluminum fins where the refrigerant passes through the copper tubing and heat is given off or absorbed by exchange with ambient air that passes through the DX battery. The aluminum slats increase the heat transfer surface of the DX battery. The heat pump process is not described in more detail. Through the heat pump, additional heat energy can be extracted from the exhaust air / exhaust air and through the warning pump process OverfOras with a higher energy content to the supply air. Solutions that only use heat pumps as "recyclers" also occur, of course.
    Although warning theater winding today is usually very efficient - a rotating heat theater winner can, for example, reach a temperature efficiency of about 85% - in many cases there is a need to supply external heat energy to cope with the heating of the supply air during all parts of the year, especially winter and parts of cough and where, of course, depending on where the air treatment plant is located geographically. The most common in the Nordic countries is that an electric heating battery or a water-connected heating battery, for example connected to district heating, is placed in the supply air after the heating theater winner to raise the supply air temperature to the desired level in cases where the heating theater winner and / or heat pump cannot handle the entire heating. In Europe, it is common to equip the air treatment devices with a so-called "frost coil", which is a heating coil for the supply of external energy in order to defrost the heat theater winner. For this purpose, the heating coil is placed in the air flow direction before the heat theater winner on the supply air side, ie the external heat energy is supplied to the outdoor air / supply air in this position.
    An edge problem with heat pumps is that the operation becomes inefficient and in some cases with high wear on the heat pump's components as follows, when the temperature of the air passing the evaporator becomes too low. It is common to recommend that the heat pump be switched off at a Nordic temperature at a tin temperature of around -15 ° C. If the heat pump cannot be used, the entire heat pump's contribution to the protection on the supply air side must be replaced with additional heat, an additional heater is then usually placed in the supply air after the heat theater winner as described above. In a heat pump, the ratio between supplied drive energy and extracted heat energy is described as the COP value, and it is common for this value to be between COP 2-5, ie the recovered energy is 2-5 times as large as the supplied electrical energy to the heat pump. If the corresponding energy is to be supplied to the supply air with the help of an electric heating battery, the cost will be directly proportional to the electricity consumption. If a liquid-connected heating coil is used instead, the corresponding energy must be produced in one way or another and supplied with the heating coil. There are advantages to installing an electric heating battery because it is a simple and relatively inexpensive installation, while a water-connected solution is significantly more expensive than the electric heating battery installation. On the other hand, the water-connected welding can be to indicate whether the steering wheel has the prerequisites for production and connection to the warning call. Additional disadvantages of today's kissings are that when the entire addition of heat is to take place in the supply air, at the coldest temperatures, the physical dimensions of the addition heater become large because it is a high power that must be managed ay. Furthermore, if an electric heating battery is used, the main ring for the system can also be affected if the system is to withstand a strong effect, which in itself makes both installation more expensive and the operating costs increase due to higher charges for a better main ring, all these disadvantages even though these operating cases only occur during a fatal event. or for a shorter period of the total operating time of the plant.
    DISCLOSURE OF THE INVENTION The present invention achieves the object of solving the above problems from the first aspect of the invention by an air treatment device according to the preamble of claim 1, which comprises an additional heater placed in the exhaust air in the air flow direction after the heat theater winner but before the precursor. Through this location and by supplying external heat energy to the air just before the evaporator extends the operating time of the heat pump, and the regulation of the supplement is optimally adapted for the supply of minimal additional heat to maintain the heat pump operation, while maintaining positive heat pump performance. Incoming air to the precursor is maintained at the right temperature and the system is balanced and operated to obtain the lowest possible operating cost. The total efficiency of the plant will be 'Atte, especially in cold climates such as the Nordic one. Furthermore, the overall efficiency is improved by the fact that it is also possible to let the heat theater gain (for example a rotating heat theater winner) continue to work to the maximum. In older solutions, one is forced to turn off the heat pump at low outdoor temperatures and let the external addition of energy account for the entire need 3 in addition to the heat that the heat theater winner Weft * supplies to the supply air. Alternatively, for example, the heat theater gain must be reduced in order for the temperature before the evaporator to increase and thus the heat pump operation to continue, but this is a bad solution because operating a heat theater winner, for example a rotor, costs "basically nothing" in relation to the high recovery rate it actually provides. . This is not economically justifiable to compensate with extended operation of the heat pump.
    According to a preferred embodiment of the air treatment device, the auxiliary heater is integrated with the passenger so that it becomes a unit. The system can then be delivered and installed as a unit, which facilitates the total installation in connection with or in the air handling unit. It is important that the additional heater is placed on the side of the passenger compartment facing the heat theater winner - on the upstream side of the evaporator - in order to fulfill the inventive concept. Developments in air treatment technology are moving more and more towards so-called "plug and play solutions" where a customer or a contractor buys a pre-packaged solution. In this way, the demarcation between who is responsible for the function becomes clearer and the supplier is clearly responsible for the function. This is advantageous for both the contractor, who only needs to connect, for example, power supply, ventilation ducts and any pipe connection, etc. and in addition, this can be a matter of the additional heater being a choice adapted to the passenger and that these work well together as a uniform solution. By integrating the additional heater with the precursor, the unit also becomes more compact, ie it takes up less space in or adjacent to the air handling unit. Older readings have no additional heaters in or in connection with the feranger and only present additional heaters on the supply air side or the solution with frost coil according to the previous background description.
    Per that Walla law cost and a simple construction solution with the simplest possible connection method, an electric heater is used, according to a preferred embodiment. Electric heaters come in a variety of variants, and depending on a customer's preference for a particular type of electric heater, the invention is not limited to offering only one type of additional heater. Although different types of electric heaters can be considered, it is easy for the installer to calculate costs for installation etc. by connecting the additional heater with electricity. An electric heater also provides a basically lossless supply of heat to the air before the evaporator.
    According to a further dangerous embodiment of the device, the additional heater is a so-called electric heating battery, or electric heater. The electric heating battery is simple in its construction and consists in its simplest form of a heating coil with electrical connection and possible control equipment. Since it is a simple and inexpensive construction, it illuminates itself to act as an additional heater in connection with the heat pump, which provides the advantages described above through a simple and inexpensive installation. An electric heating coil is easy to integrate with an air handling unit or a module in connection with the unit or the heat pump, depending on which design solution is sought. Older solutions present, as I said, additional heaters in the form of electric heating batteries, but with the difference that the heater is located in the supply air. Admittedly, the efficiency of the heater itself is just as good regardless of where in the system 4 it is placed, but the overall efficiency is important. Due to the location according to the invention, the heat pump is fully utilized, which overall gives a better operating economy than older solutions. Ideally, the heat pump can handle virtually all operation, while the electric heating battery is only needed for short periods, and it is therefore important that the auxiliary heater is a simple and inexpensive variant such as an electric heating battery. An additional advantage over heating with an electric heating coil in the supply air, as in older solutions, is that the electric heating coil does not have to have such a high effect at the new location, which affects the size of the main ring and space requirements, as mentioned above.
    According to another preferred embodiment of, the electric heater consists of one or more so-called electric heating rods. A particularly advantageous use is in combination with the precursor, if this comprises a number of voids in the lamella structure. An ordinary heating or cooling coil or a precursor usually consists of a copper tube loop for the heat-absorbing / emitting medium, in a number of rows of tubes, and a lamella package of, for example, aluminum lamellae. These slats are collared on the copper pipe with a good abutment against the pipe surface. However, it is common for the slats to be punched with a sledge for all possible positions for the copper pipes, but it is not certain that all positions are "filled" with copper pipes. The battery is dimensioned for the best effect, but given that copper is expensive, it is not efficient to fill all positions with copper in the entire cross section of the battery. It is thus necessary to integrate these electric heating rods with, in this case the precursor, by inserting them into the empty positions in the lamella package. In this way, the auxiliary heater does not take up any extra space that affects the external dimensions of the forerunner, and the auxiliary heater is in a simple way integrated in the forerunner as desired.
    However, the embodiment is not limited to the fact that the electric heating rods must be integrated in the precursor, but can equally be positioned in another way in the plant.
    A preferred form of the invention is that the electric heater consists of one or more so-called electric heating films. Electric heating film is a common type of heater for, for example, hot surfaces such as car rear-view mirrors. In ventilation, electric heating film also occurs in some markets as supplementary heating cold at, for example, heating / cooling baffles, where a plate surface is heated with the electric heating film and supply air to a room passes the hot plate surface. In this way, the air is heated by convection exchange with the plate surface. In a similar way, it is possible to warn surfaces within, for example, the air treatment unit and supply the additional heat at positions where the air passes from the heat theater winner in the direction of the evaporator. Because the electric heating film is thin, it basically takes up no extra space or causes any extra pressure drop. A solution with electric heating film does not therefore have to affect the very basic design of the air treatment unit, which reduces the cost of the function and the functional flora in the product range without affecting the manufacture of the air treatment unit components. Additional heaters according to today's readings, in a form that does not affect the structure of the air handling unit, are usually mounted as an extra detail in the duct system on the supply air side, ie it is a separate component that must be handled and installed instead of one: 0g "plug & play" - Solution according to the invention.
    A particularly preferred embodiment of the invention is that the heat theater winner is an adjustable rotary heat theater winner. The rotating heat theater winner has a high temperature efficiency and rotates at a certain speed at full operation, for maximum recovery of heat from the exhaust air and transfer of heat to the supply air. On the outside air side, there is also the heat pump's precursor for absorbing heat energy from the air that has passed the heat theater winner on its way out to the outdoor air, as previously described. A rotating heat theater winner does not consume much energy during operation. The only energy needed is to rotate the rotor wheel at a constant speed. In other words, it does not cost much to let the rotor provide for maximum heat theater gain and due to the high temperature efficiency it is Onskvart with high utilization rate of the rotating heat theater winner, there is no heat demand.
    The ignition temperature, on the exhaust air / exhaust air side, before the evaporator is affected by how much heat energy is recovered by the rotating heat theater winner, why a prolonged operation of the heat pump can also be achieved by down-regulating the rotor speed, ie reducing the heat recovery. and before the Forerunner. However, the total efficiency speaks against this because the operation of the rotor consumes less energy than that of the operation of the heat pump to compensate with the corresponding heat supplement, gOr. Further optimization and collaboration also takes place with the auxiliary heater and the interaction between these components in relation to different operating cases is important, because in some cases, or for shorter periods, it may be necessary to reduce rotor operation, in other cases full rotor operation and additions, etc. . With other aids, it is advantageous to use an adjustable rotary heat theater winner in order to be able to optimize the operation at different times of the year and under certain conditions, in cooperation with the heat pump's operation and the use of the auxiliary heater. By constantly steering the unit to as good a total efficiency as possible, a legal operating cost is obtained.
    According to an alternative embodiment, it is preferable to use an adjustable cross-section heat exchanger as an alternative to using an adjustable rotary heat theater winner. These are adjustable in that they are sectioned, whereby it is possible to open and close dampers that regulate the amount of air through, or next to, the heat theater winner. True benefits exist, as above, even if the regulation is somewhat more blunt, but in some cases sufficient.
    For cases where the additional heat, according to the wishes of, for example, a customer, must be water-borne, the additional heater is of a sedan type. The inventive idea is the same, that is to say to supply the heat in the position, in the flow direction after the heat theater winner but before the evaporator. Water-borne solutions can be justified if the plant has access to external heating, other electricity, for example district heating or the like. The invention is not limited to a special type of external additional alarm, but it is the position that enables extended operation of the heat pump that is the most important.
    According to a preferred embodiment of the invention, the air treatment device comprises a control equipment, which is arranged to softly control the electric heater, for a substantially continuous adjustment of the heating effect. This is preferred by a so-called TRIAC, which states that it is possible to balance the heat output to see that the temperature between the heat exchanger winner and 6 evaporators is sufficient for the heat pump to remain in operation, even if the temperature is low. The soft control meant that the heating power is adjusted in small steps, which gives a basically continuous power curve for the power delivered in the heater. At least one of the heating coils / rods / films has this soft control. The most common solution for older people is that the control takes place by switching on different power stages or combinations thereof, which gives a more blunt control.
    According to a further preferred embodiment, the control equipment is arranged to stepwise control the power output of the electric warner, preferably through one or more power steps, and that the control equipment also combines the soft control with the stepwise control for best possible adjustment of the power so that the temperature between heater and evaporator is balanced. for minimal energy consumption and best overall efficiency.
    From the second aspect of the invention, the object is achieved by reading the above-mentioned problem by a method for heating air according to the preamble of claim 12, which comprises that additional heat is supplied through an additional heater placed in the exhaust air in the air flow direction after the heating theater winner but before the precursor. additional heat on the supply air side. By supplying external heat energy to the exhaust air just before the evaporator, the operating time of the heat pump in the system is extended in cases where the heat pump normally has to be switched off due to too low a temperature of incoming air to the evaporator. In the older runs, when the heat pump is switched off, all the heat energy needed to reach the right supply air temperature, in addition to that recovered with the heat theater winner, is supplied with an addition on the supply air side. The difference is that by adding external heat to the supply air side, the exchange in the best case is 1: 1 of supplied energy versus the obtained heat energy, while for the heat pump at least one exchange is - laid straight - 1: 3. The regulation of the additional heat is optimally adapted for the supply of minimal additional heat to maintain the heat pump operation, while maintaining the positive performance of the heat pump. Incoming air to the precursor is maintained at raft temperature and the system is balanced and operated to obtain the lowest possible operating cost. The overall efficiency of the plant will be better, especially in cold climates such as the Nordic one. Furthermore, the overall efficiency is improved by the fact that it is also possible to allow the recovery to continue to work to the maximum. In older readings, you are forced to turn off the heat pump at, for example, an outdoor temperature of about -15 ° C, and let the external addition of energy, placed in the supply air, stand for the entire need, beyond the heat that the heat theater winner overtakes & into the supply air.
    According to a preferred embodiment of the process, the supply of external heat energy to the exhaust air is effected, via the additional heater, when the temperature before the evaporator reaches a lower spruce value for which the heat pump would normally stop, for example about -15 ° C. By placing a temperature sensor in the exhaust air after the heat theater winner and before the evaporator, the current temperature of the air that is on its way into the evaporator is measured. When a lower limit value is reached, which is preferably a temperature slightly higher than the lower limit value of the heat pump for operation, the heating of the air via the supplement is reduced. Of course, the invention is not limited to the fact that the supplement can only be started at the lower spruce value, but all the time it is the total efficiency that is interesting, 7 it will be said how energy-efficiently the plant can be operated. The optimization of the operation is done by balancing heat pump operation, heat theater extraction and additional heat.
    According to a further preferred embodiment of the invented method, the supply of the external heat energy is started, via the additional heater located before the evaporator, when freezing on the passenger is indicated. How the indication gars is defined does not have, but there are a number of ways to detect freezing in the evaporator, the important thing is that the indication initiates a defrosting sequence. The faranger is defrosted for a suitable time with the help of the addition of external heat energy, alternatively with combinations of other defrosting techniques. The plaintiff has filed a patent - SE 1200784-5 - which describes double-sided defrosting of a precursor in an air treatment plant with an adjustable heat theater winner and a heat pump, similar to the plant in this application. In SE 1200784-5 the defrosting takes place on both sides by raising the temperature of the refrigerant inside the evaporator in different ways, at the same time as the heat theater winner is regulated down to raise the temperature of incoming air to the evaporator and thus achieve faster defrosting by heating both inside and outside. With the present invention it is possible to combine or alternate the outside temperature of the exhaust air by either using the auxiliary heater and / or the adjustable heat theater winner to achieve the double-sided defrosting.
    According to a preferred embodiment of the invented method, the auxiliary heater is an electric heater and the air treatment device comprises a control equipment, which softly controls the electric heater, for a substantially continuous adjustment of the heating effect. This is done dangerously through a so-called TRIAC, which means that it is possible to balance the heating effect so that the temperature between the heat exchanger and the evaporator is sufficient for the heat pump to remain in operation, even if the temperature is normal. The soft control meant that the heating power is adjusted in small steps through 0-10VDC or communication, which gives a basically continuous power curve for the power delivered in the heater. At least one of the heating coils / rods / films has this soft control. The most common in older solutions is that the control takes place by connecting different power stages or combinations of them, which gives a more blunt control.
    According to a further preferred embodiment of the method, the power output in the electric heater is controlled stepwise, dangerously through one or more power steps, and the control equipment also combines the soft control with the stepwise control for best monthly adjustment of the power so that the temperature between the heater winner and the passenger is balanced and and best overall efficiency.
    Through the invention, a number of advantages over known solutions have been obtained: Extended operating time for the warning pump, which replaces a need for heat addition in the supply air, which gives a better utilization of additional protection energy from (in the best case) 1: 1 to the order of 1: 3-1: 5 if you compare electric heating battery placed in the supply air and an electric heating battery placed before the passenger.
    Less start / stop for the heat pump, and thus less wear. 8 Continued operation of the heat pump at low temperatures meant increased wear - now the heat pump is never allowed to run at too low temperatures but through a small addition of heat energy before the precursor, the heat pump can work under favorable conditions.
    An escape type of defrosting of the evaporator with the help of the auxiliary heater, which also makes it possible for heat theater winners to continue to work with full recovery of both exhaust air and supply air, in cases where it is favorable from a total economic operating perspective.
    Smaller dimensions and lower amperage on the main ring compared to if the corresponding power requirements were to be supplied with electric heaters in the supply air, which gives better overall economy.
    In combination with an adjustable heat theater winner, high flexibility is obtained for operation, which enables better control towards good overall efficiency.
    Soft control in combination with stepwise control of different power loops in the electric heater means that a flexible and precise control of the power from the auxiliary heater is obtained, which means that the temperature before the precursor is adapted for the upright heat pump operation and optimal overall efficiency.

    The constructive embodiment of the present invention will become apparent in the following detailed description of an embodiment of the invention with reference to the accompanying figures which show a preferred, but not limiting, embodiment of the invention.
    Detailed description of the figures Fig. 1 shows a General sketch of the principle of an air treatment device (1) according to the prior art, which comprises an air treatment unit (2), a heat theater winner (3) - in this case a rotating heat theater winner, a supply air fan (19) and an exhaust air fan, respectively. (20), a heat pump (6) including a feranger (7) and a condenser (8). The heat pump (6) can be of varying type and is not defined or explained further. The air handling unit (2) comprises a first air stream (4), which in the figure 9 is positioned in the upper half of the air handling unit (2) and is directed to the right to the left. The first air stream (4) comprises fresh air (15) in the direction of the air flow, which after the heat theater winner (3) is then named exhaust air (16). Furthermore, the air handling unit (2) comprises a second air stream (5), which in the figure is positioned in the lower half of the air handling unit (2) and in the figure directed from left to right. The second air stream (5) comprises in the flow direction of the air outdoor air (17), which after the heat theater winner (3) is named supply air (18). In the first air flow (4) the evaporator (7) is located, ie the DX battery which for the current operating situation warns the evaporator (7). The evaporator (7) is arranged in the flow direction after the meter winner (3) and heat is extracted from the exhaust air (16) through the heat pump process. In the second air flow (5), in the flow direction after the heat meter winner (3), another DX battery is arranged, which becomes a condenser for the heat fall and through the heat pump process the heat is left to the supply air (18) with the help of the condenser (8). The heat pump process which is then not discussed further in this application. The figure also shows an additional heater (9), which in the present case is located in the second air stream (5), before the outdoor air (17) reaches the heat theater winner (3). This location occurs mainly in central and southern Europe and acts as a defrost for the rotating vermeater winner (3) - a see called "frost coil". The addition of varnne to the supply air side can be in the form of electric heating or water-borne heat. However, this solution is a pure addition to the supply air side, which does not improve the operation of the heat pump at low temperatures and is a common overall economic solution to the present invention. However, the purpose is partly different.
    Fig. 2 shows a general sketch of the principle of the air treatment device (1) according to existing technology and with input components similar to the description above with respect to Fig. 1. The difference compared to the solution in Fig. 1 is that the external heat energy is supplied by the additional heater (9) placed in the supply air (18). in the second air flow (5) and in the flow direction of the air after the rotating heat theater winner (3).
    This is a very friendly solution in the Nordic countries to supply external heat energy to maintain the temperature of the supply air (18). With this solution, however, there are the previously described disadvantages that at low outdoor temperatures the heat pump (6) is switched off and the additional heater (9) must be able to cope with the entire heat demand beyond what the rotating heat theater winner (3) provides. Thus, the auxiliary heater (9), whether it is an electric heating coil or a water-connected bath, must be dimensioned to cope with these power peaks, with the result that the dimensions of the auxiliary heater become large. Furthermore, since the auxiliary heater is electric, the main ring of the plant may also need to be dimensioned up in comparison with a solution according to the invention. The additional heater (9) can, for example, be electrically or liquid-connected.
    Fig. 3 shows a schematic diagram of the air treatment unit (1) according to the invention where the external heat energy is supplied by the additional heater (9) being placed in the first air flow (4), i.e. on the exhaust air side, and in the air flow direction after the rotating heat exchanger (3). ) and before the passenger compartment (7). The additional heater (9) can be of varying type according to the inventive idea, but preferred in the form of an electric heater (10) and those in the form of a so-called electric heating battery (11). Other embodiments presented in the figure are alternative embodiments of the additional heater (9), in the form of one or more electric heating rods (12) or one or more electric heating films (13). Regardless of the type, the additional heater (9) can be a separate part or integrated together with the front (7), however, the addition of heat must take place before the front (7). Figure 3 also shows a temperature sensor (14) for supplying a temperature Ti before the precursor (7) and the supply are used to determine whether the heat pump (6) should be in operation or not and to control whether the auxiliary heater (9) should heat or not. A control equipment (21), not shown, is used for controlling the auxiliary heater (9), the operation of the rotary heat exchanger (3), the operation of the heat pump (6) and preferably for Other operation of the input and controllable components of the air handling unit (2). The auxiliary heater (9) is used above with the advantage as a defrost when indicated freezing in the evaporator (7). As previously explained, the location meant that the heat pump (6) is used significantly more than in conventional plants, which contributes to better overall economy and smaller dimensions of the heater, etc.
    Figs. 4a and 4b show schematic bar graphs of energy requirements and energy consumption at low outdoor temperature of a standard air handling unit (2) according to current technology compared to an air handling unit (2) offered according to the patent application. Figure 4a shows that there are of course true energy needs regardless of which installation is involved and that the heat theater extraction (VAV) from the exhaust air (15) and Transfer to the supply air (18), through the heat exchanger (3), contribute greatly to meet the energy demand. This item (VAV) varies with the type of heat theater winner (3) and can amount to around 85% for a rotating heat theater winner. For a standard unit according to current technology - the left-hand pillar - the addition (TS) of external heat energy must fill the remaining energy needs beyond what has been recovered through the warning theater winner (3). In the right-hand bar - patent - it is stated that the addition (TS) of external energy, in this case electrical energy, constitutes a smaller part while the heat pump (6) provides the rest of the energy requirement (VP) by tiff & the external addition (TS), partly as driving energy to the heat pump (6) and as an extra supplement through the supplementary heater (9) if necessary to keep the warning pump (6) running at the low outdoor temperature.
    Figure 4b schematically studies the energy consumption of the air handling unit (2) according to current technology compared with technology according to patent application. The energy required to drive the rotor (VAV) of the rotating heat theater winner (3) is apparently law, which is why it justifies using this as much as possible with high heat theater gain. In a system according to current technology - standard - the heat pump (3) is switched off and the supplement (TS) stands for a high energy consumption and a high power output from the electric heating battery (10), which also must have larger dimensions and probably higher amperage on the main ring compared to the new way of supplying heat energy. The size of the main ring varies depending on the unit size and variant flora of electric heating batteries. With a solution according to the present invention, the addition (TS) of external energy constitutes the electricity that is used to power the heat pump and to heat with the supply air heater (9) to maintain the heat pump operation. It seems that energy consumption is reduced and the savings become stormy the colder it is and the longer period that otherwise a conventional plant would leave the heat pump standing still. Beyond this, as I said, there are the advantages regarding dimensions and main ring etc. 11 PARTS LIST 1 = air treatment device 2 = air treatment unit 3 = heat recovery 4 = first air flow 5 = second air flow 6 = heat pump 7 = precursor 8 = condenser 9 = additional heater 10 = electric heater 11 = electric heating coil 12 = electric heating film 16 = electric heating rod 16 = temperature heating 16 = temperature = exhaust air 17 = outdoor air 18 = supply air 19 = supply air fan 20 = exhaust air fan 21 = control equipment TS = supplement (external supply vame energy) VAV = heat theater extraction (recovered heat energy) VP = heat pump
