    W U 20 25 30 35 2 claims specified in the claim. Preferred embodiments of the invention are defined in the dependent claims.
    Brief Description of the Drawings Hereinafter, a preferred embodiment of the invention will be described with reference to the accompanying drawings, in which: Fig. 1 schematically shows a climate system for a space according to the present invention; Fig. 2 schematically shows the underlying idea of the present invention at an undesired temperature rise; Fig. 3 schematically shows the underlying idea of the present invention in the event of an undesired temperature drop; and Fig. 4 shows comparative bar graphs for cold weather and warm weather.
    Detailed Description of the Prior Art and a Preferred Embodiment of the Present Invention The climate system shown in Fig. 1 is a combination of prior art and technology according to the concept of the present invention, the space in which the climate is to be controlled being denoted by U.
    The air conditioning system shown in Fig. 1 comprises a supply line 1b, a heat exchanger 3b and a return line 5b.
    The supply line 1b extends into the heat exchanger 3b and the return line 5b extends away from the heat exchanger 3b.
    The supply line 1b and the return line 5b are connected to each other inside the heat exchanger 3b, the connection being able to be formed as a first transfer loop which can preferably be helical.
    The supply line lb is based on a central plant, e.g. a district heating plant, and the return line 5b ends in the central plant. In lines 1b and 5b an energy storage medium is transported, e.g. water, the temperature of the energy storage medium being determined by the central plant. The central plant thus delivers an energy storage medium in the supply line, this energy storage medium having a temperature which is normally determined by the central plant. The heat exchanger 3b is normally located in a local unit LE, e.g. an apartment building, to which the central plant supplies energy via the energy storage medium.
    From the heat exchanger 3b a supply line 7b extends which extends to a radiator 9b and from the radiator 9b an removal line 10b extends which extends back to the heat exchanger 3b. The supply line 7b and the removal line 10b are interconnected both inside the heat exchanger 3b and inside the radiator 9b so that the supply line 7b and the removal line 10b form a closed loop. Inside the heat exchanger 3b, the supply line 7b and the removal line 10b are interconnected by means of a second transfer loop (not shown) which may preferably be helical.
    A first control center 11b is arranged in the local unit LE, by means of which staff of the local unit LE can perform various control measures with regard to the energy supply to the space U.
    A motor valve 12b is mounted on the return line 5b for controlling the flow in the return line 5b, this control also influencing the flow in the supply line 1b since the supply line 1b and the return line 5b are interconnected. The control of the motor valve 12b takes place via the first control center 11b. A first outdoor temperature sensor 13b is connected to the first control center 11b. A supply temperature sensor 14b is mounted on the supply line 7b, between the heat exchanger 3b and the space U. The supply temperature sensor 14b is connected to the first control center 11b.
    A pump 15b is mounted on the supply line 7b, whereby the speed of this pump 15b can be varied, the variation of the speed taking place in dependence on pressure changes in the supply line 7b. These pressure changes are effected by a thermostat (not shown) arranged in connection with the radiator 9b, which regulates the flow area in the supply line 7b.
    What has been described above represents prior art.
    It can generally be said that the prior art constitutes a relatively "blunt" instrument for controlling the climate in the space U. Reference numerals referring to prior art end with "b" while reference numerals referring to that which refer to to the concept of the present invention ends with "a".
    According to the concept of the present invention, the air conditioning system according to Fig. 1 has an indoor temperature sensor 1a, a second outdoor temperature sensor 3a and a second control center 2a which preferably comprises a frequency converter FO.
    The indoor temperature sensor 1a and the second outdoor temperature sensor 3a are connected to the second control center 2a. The pump 15b is also connected to the second control center 2a, whereby the speed of the pump 15b can be controlled by means of the frequency converter FO included in the second control center 2a.
    The background reasoning for the present invention is as follows. Depending on the thermal dynamics properties of a space, a temperature change will take different lengths of time. A "heavy" frame entails longer time differences and thus greater heat storage capacity compared with a "light" frame.
    The heat losses depend on both the indoor and outdoor temperatures as well as the space's transmission and ventilation loss factors.
    In addition, the heat demand of the space is affected by the thermal dynamics properties.
    The idea of the present invention is to let both the sluggish dynamic heat properties and the more direct heat losses together regulate so that an even indoor temperature is obtained.
    Fig. 2 schematically shows a reasoning around power balance, this reasoning leading to a formula which indicates the flow change to be applied to the energy storage medium in the closed loop containing the supply line 7b and the removal line 10b, this flow change taking place by means of the pump 15b. Fig. 2 shows a case where an undesired increase in the temperature in the space takes place.
    In FIG.
    S2H. The first stack S1H symbolizes the power shown 2, a first stack S1H and a second stack are supplied to the space, a first part of the supplied NOW being constituted by the power supplied via a radiator 9b. . A second part of the added power heating system. In the above, the heating system consists of so-called free effect. It can e.g. consists of solar radiation through windows of the space, of the heat emitted by people staying in the space or of the heat emitted by a switched on computer or TV. This is only an exemplary enumeration.
    Some of the added free power, together with the added heating power, gives a desired indoor temperature. The second part of the free energy gives rise to a temperature excess, AtL. The effect removed from the space is symbolized by the bar S2H.
    It includes ventilation losses, ie. heat that is sucked out via the ventilation system, partly transmission losses, ie. heat flow through the space's climate shell, e.g. floors, walls, windows, ceilings, ie. the surfaces that define the space. In addition, heat effect is removed from the space by storing heat in the space of the space. According to the concept of the present invention, it is assumed that the applied power from the heating system / radiator 9b corresponds to the removed power caused by the ventilation and transmission. This abducted effect can be termed (ZUÄHICV) (timiimacani. 'Tu) f there! u is an average of the heat transfer coefficient for walls, ceilings, etc .; A is the enclosing area of the floor, etc.); n is specifically airflow window, (climate screen, Roof, walls window (number of air revolutions per hour, in a home says the minimum requirement that it should be 0.5 rpm, which means that all air is replaced after 2 hours); C is the air heat capacity; V is the volume of the building or room.
    When it comes to finding out tLknnæmu_for the current climate system, you can proceed in the following way. By studying the effect that the air conditioning system produces during different time periods of the year, the time period can be defined when the effect is at a constant and low level. In this case, it can be concluded that during this time period the air conditioning system only produces power for hot water and consequently ti¿LuEumL is equal to tu, ie. the current The current outdoor temperature tu is obtained from measurements of the same. the outdoor temperature during the current time period. At least for Sweden, this happens regularly all year round for a very large number of places.
    The stack S2H also comprises two parts which together are denoted Increase of transmission and ventilation losses due to increase of the indoor temperature from the free power in the space. transmission and ventilation depend on the difference In this context, it should be noted that both between the measured indoor temperature tißægi the space and the outdoor temperature. If the indoor temperature in the room is raised and the outdoor temperature is unchanged, the ventilation will increase and the transmission losses will also increase. This total increase can be called (ZuA + ncV) AtL where Atiär unwanted temperature increase in space.
    The stack S2H also comprises a part called Storage, this part corresponding to the power absorbed by the frame surrounding the space and stored as energy in the frame. According to the concept of the present invention, Gratis corresponds to the power supplement which partly gives an increase in the indoor temperature from tLklimatanL to tißeg and partly gives a storage of heat power in the body. Some part of Free gives an unwanted temperature rise in the room. The unwanted transmission and ventilation power dissipation can be written: (EuA + ndV) Ati.
    When looking at the rest of the bars S1H and S2H, the following power relationship is obtained: Rise system = (zuA fi ïc-V) (timlimatanlftu) - The added power from the heating system can also be written: qxk (tF-tR), where: q is the normal flow in the closed the loop containing the supply line 7b and the removal line 10b; W Ü 20 25 30 35 7 k is a constant which causes the power according to the given formula to be expressed in watts; tf is the temperature of the energy storage medium in the supply line 7b; and tR is the temperature of the energy storage medium in the removal line.
    According to the reasoning above, qqk (tF'1 -'- R) = (211A + I1CV) (trklimacaniftu) - To counteract the temperature rise Ati, the flow in the circulation circuit must be reduced by: Aq xk (tF-tg), which corresponds to the power reduction the undesired temperature rise Ati gives rise to through increasing ie. (2uA + ncV) AtL According to this reasoning: Aq x k (tf-tg) = (2uA + ncV) Ati.
    After formation of the ratio Aq / q and simplification, Aq / q = transmission and ventilation losses, Ati / (tLkh fl mæmL-tu) are obtained. This connection provides the following information. In the case of a temperature increase Ati registered by the indoor temperature sensor 1a, the change / decrease Aq / q of the flow to take place is calculated, given the formula: Aq / q = Ati / (tLklimatanL-tu). The change is effected in percentage terms, according to the above in practice by changing the speed of the pump 15b by means of the frequency converter FO of the second control center 2a.
    Fig. 3 also schematically shows a reasoning around power balance, temperature reduction. in this case an undesired one is illustrated. In Fig. 3 a first stack S1S and a second stack S2S are shown. The first stack S1S symbolizes the power supplied to the space, a first part of the supplied power being the power supplied via an I Fig. Of a radiator 9b. A second part of the added power heating system. In the above, the heating system consists of so-called free effect and is denoted in Fig. 3 by "Free". It can e.g. consists of solar radiation through windows of the space, of the heat emitted by people staying in the space or of the heat emitted by a switched on computer or TV. This is only an exemplary enumeration. Since there is a lowering of the temperature in the space, energy stored in the frame will be delivered as an effect to the space, this power delivered in Fig. 3 being denoted by "Emitted". 10 U 20 25 30 35 8 The emitted effect from Free and Delivered causes a certain temperature increase in the room, but not such a large temperature increase that the desired temperature in the room is achieved. The difference between the measured temperature in the room and the desired temperature in the room is called Ati and is thus a temperature drop.
    The effect removed from the space is symbolized by the bar S2S. heat that is extracted via the ventilation system. It includes ventilation losses, ie. partly transmission losses, ie. heat flow through the space's climate shell, roof, ie. defines the space. According to the concept of the present exv. floors, walls, windows, the surfaces of the invention it is assumed that the applied power from the heating system / radiator 9b corresponds to the removed power caused by the ventilation and transmission.
    The stack S2S also includes transmission and ventilation losses as a result of the temperature increase in the space from the free power and the power emitted from the body in the space. As pointed out above, this temperature increase in the space is not sufficient for the desired indoor temperature to be achieved.
    To counteract the unwanted temperature drop Ati, the flow in the circulation circuit must be increased by: Aq x k (tr-tk), which corresponds to the power reduction that the temperature drop Ati gives rise to through reduced transmission and ventilation losses and thus lower indoor temperature, ie. (2uA + ncV) Ati. According to this reasoning: Aq x k (tF-tR) = (2uA + ncV) Ati. After formation of the ratio Aq / q and simplification, Aq / q = Ati / (t-hklimtanL-tu) is obtained. This connection provides the following information. In the case of a temperature drop Ati registered by the indoor temperature sensor 1a, the change / increase Aq / q of the flow which is to take place, expressed as a percentage, is calculated according to the above formula: Aq / q = Ati / (ti, k1imatan1_-tu). The change is effected in practice by changing the speed of the pump 15b by means of the frequency converter FO of the second control center 2a.
    In this context it should be mentioned that the above formula does not work for the special case tLkhnmæmL = tu because in that case the denominator in the formula becomes equal to zero and the flow change Aq / q becomes infinitely large.
    W Ü 20 25 30 35 9 When studying the formula Aq / q = Ati / (tLkhnmzm -hg, 0.5 °, flow change Aq / q is realized when the difference between that for a certain value of Ati, e.g. a larger indoor temperature is obtained which the air conditioning system can deliver ti¿LmmumL and the actual outdoor temperature tu is small.
    This may seem strange but will be explained below with reference to Fig. 4.
    The upper bar graphs in Fig. 4 represent cold weather while the lower bar graphs in Fig. 4 represent warm weather. The two upper bar charts have S2K while the two lower bar charts have been designated SlV resp. S2V.
    In the two bar graphs for applied power SlK and ie. designated SlK resp.
    SlV, part of the bar graph s.k. free effect denoted by the left bar graphs in Fig. 4, forms an upper G. Part of this free effect is denoted by "Extra" and is the heating effect that gives a temperature increase Ati.
    The free effect has been assumed to be as great in cold weather as in warm weather.
    A comparative study of the left bar graphs S1K and S1V in Fig. 4 shows that the applied power U from the heating system is less in hot weather than in cold weather.
    SZK and S2V represent power losses / the abducted power in cold The right bar graphs in Fig. 4, ie. resp. warm weather. The bar graphs SZK and S2V denote the transmission and heat losses resulting from the extra free energy with (ZuA + ncV) Ati. These transmission and heat losses are assumed to be as large in cold as in hot weather. A comparative study of S2K and S2V suggests that (ZuA + ncV) (ti-tu) is generally less in hot transmission and ventilation losses as weather than in cold weather. Transmission and ventilation losses (EuA + ncV) Ati resulting from the extra free energy thus constitutes a larger part of the power losses in hot weather than in cold weather. In hot weather, a larger flow change Aq / q of the energy storage medium is thus required to compensate for the power losses from the extra free energy. This explains why Aq / q W 10 receives a larger value when ti¿LuwumL and the actual outdoor temperature are close to each other.
    Possible modifications of the invention The above-described embodiment of a climate system according to the present invention includes a loop in the form of a radiator 9b which connects the supply line 7b with the removal line 10b. Within the scope of the present invention, however, the loop can be designed in a number of different ways. limiting purpose it can be mentioned that the loop can be in the form of I exemplary and not underfloor heating, ie. the loop is located in the floor of the room.
