    A solar collector comprises a pipeline, which is usually designed to contain a heat-carrying medium for heat transfer between the solar collector and a surrounding environment. The pipeline is positioned so that it can be aggravated by the sun's radiation. The solar collector comprises a chemical heat pump of the hermetically sealed unit tube type with a reactor part, an evaporator / condenser part and a passage between them. The area of the unit pipe, which contains the chemical heat pump reactor part, is located in heat-conducting contact with the first pipeline. In this way, the thermal chemical heat pump can be charged, when sunlight thickens the first pipeline, and thereby the area of the unit pipe with reactor part is also heated. The unit tube may be surrounded by a thermo-insulating part of the thermo-type, which comprises an evacuated space located between an outer wall and an inner wall. The inner wall may then, at its outwardly directed surface, comprise a radiation-receiving part, which is arranged for converting solar radiation into heat and which is in heat-conducting contact with the first area and the first pipeline.

    The range areas for such a thermal solar collector are lower than for previously known thermal solar collectors.
    The chemical heat pump is designed as a closed tube of the unit tube type, which can be relatively elongated. One half of the unit pipe or generally an area at a first end constitutes or contains the reactor part of the heat pump, also called an accumulator part, and the other half of the unit pipe or generally an area at a second end constitutes or contains the evaporator / condenser part of the heat pump. Each of the halves or ends of the unit tube may, if required, be mounted in its respective heat-insulating part, of which at least the heat-insulating part, which is arranged at the reactor part of the chemical heat pump, is light-transmissive. The heat-insulating parts can, for example, be of the thermo type and, for example, comprise an evacuated space.
    The first region of the unit tube containing the reactor part and the second region of the unit tube containing the evaporator / condenser part are also surrounded by respective heat exchangers or heat transfer parts for cooling or heating a heat-carrying medium such as water. At the first area of the unit tube, a sun-catching surface may also be present, which is part of a radiation-receiving part and is arranged to convert incoming solar radiation into heat. The sun-catching surface can be arranged, for example, in or on the heat-insulating part or on the heat-transferring part. At the second area of the unit tube, which constitutes or contains the evaporator / condenser part, there is no such trapping surface. Due to the lack of a sun-catching surface and due to the heat-insulating part surrounding the second area of the unit pipe, if such a part is provided, the heating of the second area may be less, in particular considerably less, than the heating of the first region, so that the second region will maintain a temperature which is lower than the temperature in the first region when the sun's radiation is incident on the solar collector. This also applies if the second power line is located in direct connection to the first area, such as at or inside the solar collector itself and, for example, is also hit by solar radiation. The second area may also or alternatively be in some suitable manner cut off from the sunlight.
    An efficient thermal solar collector that has increased functionality, such that it can also be used for the production of cooling from solar energy, can thereby be achieved.
    In addition, the chemical heat pump can work according to the hybrid principle and have a particularly efficient design.
    Thus, a chemical heat pump designed as a unit pipe may comprise, for example, a vacuum sealed pipe in such a way that an area at a first end of the unit pipe is used as an evaporator / condenser and an area at the other end of the unit pipe is used as a reactor and the area between the two pipe halves are used for steam transport. The process in the chemical heat pump 3 can take place according to the so-called hybrid process, see for example the above-mentioned published international patent applications WO 00/37864 and WO 2007 / 139476. The hybrid process comprises two phases, a charging phase and a discharge phase. In the charging phase, a salt which settles in the reactor part is dried, so that a ligand or a sorbate, eg water, is released from the salt and transported in the gas form over to the evaporator / condenser, where it / it is condensed. When most of the ligand previously bound in the salt has been transferred to the evaporator / condenser, the chemical heat pump is charged. In the discharge phase, the ligand moves in the opposite direction and binds again in the salt.
    The benefit of this process is that heat energy and cooling energy can be obtained as in other heat pumps.
    Furthermore, in the chemical heat pump a matrix can be used for carrying and retaining the salt, which is generally referred to as active substance, both in its solid state and in its fl liquid state or its solution phase, see the mentioned international patent application WO 2007/139476. such a matrix is typically an inert material such as alumina and it has pores which are permeable to the vapor phase of the ligand. The active substance is bound to the walls of the pores. The matrix may be of a material which generally comprises separate particles, and may be in the form of, for example, a powder or a compressed carrier material.
    The chemical heat pump can generally be designed so that it can easily be assembled with or included in a solar collector. The chemical heat pump can also be designed so that it can be produced in a coherent process and thus enable mass production and at the same time obtain a low production cost.
    A thermal solar collector with a built-in chemical heat pump can, at least in some cases with a suitable design, have one or more of the following advantages: - The solar radiation hits the reactor part of the chemical heat pump almost directly, so that an intermediate hydraulic energy transfer can be completely removed. associated heat exchanges. This avoids heat losses, which can amount to about 15 - 40% of all energy, which means that the thermal solar collector has a higher solar efficiency. With a higher solar efficiency of each solar collector, a solar collector system comprising solar collectors of the type described here can be dimensioned down compared to a solar collector system comprising traditional solar collectors in combination with an absorption protection pump. This of course reduces the cost of the solar panel system and reduces the end user's repayment period.
    - A higher temperature in the reactor part of the chemical heat pump can be obtained during irradiation, so that other salts can be used, which have a larger temperature difference, so-called AT, whereby the chemical heat pump can make useful (high exergy) heat energy from a relatively cold but free energy source or make useful cooling energy from a hot, free source, for example air of 35 ° C. This means that 4 costs for obtaining a so-called spring sink can be reduced.
    - The distributing hydraulic system for the protective medium can be made simpler and at lower costs.

    DETAILED DESCRIPTION A thermal solar collector comprises a chemical heat pump S of the unit tube type, see the above-mentioned international patent applications WO 2007 / lS9476 and WO 2009/070090, which are designed as a closed tube, which can be relatively elongated, ie have a ratio between diameter and length amounting to at least 1:10, more commonly perhaps at least 1:20, see Fig. 1. A first area Sa at one end of the pipe, with a length corresponding to, for example, about half or slightly less than the total pipe length, constitutes or contains the reactor part of the heat pump and a second area See at the other end of the pipe, also with a length corresponding to, for example, approximately half or slightly less than the total length of the pipe, forms or contains the heat pump's evaporator / condenser part. Chemical heat pumps with an internal structure other than that shown in the mentioned international patent applications can of course also be used as chemical heat pumps with a solid or surface-active substance or absorber.
    The unit tube S may thus comprise a first and a second area Sa, Se, which are connected to each other by an intermediate area Sc. These different areas of the unit pipe are thus pipe parts, each of which comprises an internal space. The inner space of the intermediate region Sc constitutes a channel for the passage of gas of a volatile liquid between the inner spaces in the first and the second region Sa, Se, ie between the reactor part of the chemical heat pump and the evaporator / condenser part. The pipe section in the intermediate area Sc can be narrower than the pipe sections at the ends of the unit pipe S. As shown in Fig. 1, the unit tube can have a substantially straight design, so that its different areas Sa, Se, Sc can have the same longitudinal axis. The different areas can be cylindrical as well as circular-cylindrical and they are then suitably also concentric, ie have the same axis of symmetry. Other designs are conceivable, however, and for example the first and the second area Sa, Se may have a substantially straight design while the intermediate area Sc is curved, see Fig. 2a. The first and the second area Sa, Se can then lie parallel next to or next to each other and the intermediate area Sc is then U-shaped, ie gives a change of direction of 180 ° for fl uid, which flows through the intermediate area Sc.
    The first and the second protective wire Sa, Se of the unit tube S may be unconnected by or be installed in separate heat-insulating part 5a, Se, which may consist of heat-insulating layers, heat-insulating shells or heat-insulating sheaths. The heat-insulating parts 5a, 5e prevent conduction of heat from and to the unit pipe S, ie they prevent the heat exchange of the unit pipe with the environment outside the heat-insulating parts, and they can be of the thermo type and for example comprise an evacuated space. At least the heat-insulating part 5a at the area of the unit tube S, which contains the reactor part, can be at least partially transmissive to light, i.e. it can transmit light, in particular sunlight. Such a heat-insulating part 5a can be constituted by a double-walled glass tube, the space between which the two walls, its inner wall and its outer wall, are closed and evacuated, i.e. essentially contain vacuum or gas of low pressure such as gas of very low pressure, see Fig. 3. Heat-insulating parts Sa, Se of this design can be used at both areas 3a, 3e of the unit pipe 3.
    Furthermore, at the first control area 3a of the unit tube 3, which contains the reactor part, a reactor 7 can be present, see Fig. 5a. Such a rectifier 7 has a light-reflecting surface, which reflects light, which enters in one or your predetermined directions, towards the first area of the unit tube and in particular towards a sun-catching surface at this area, see below. A unit tube 3 with associated heat-insulating parts Sa, Se and reactor 7 can then constitute a solar collector or a solar collector unit or a solar collector element 9. The reflector 7 can comprise a suitably bent metal plate 7 'and the same metal plate 7' can as shown comprise bent portions , which constitute reactors for adjacent solar collectors 9. A solar collector module 9 'may then comprise a number of solar collectors 9, which have reactors 7 formed of the same sheet metal.
    Several solar collector modules 9 'can be assembled according to energy requirements, see Fig. Sb. Thus, as shown for the case of straight unit tubes 3, the reactor plate 7 'in each module 9' may have portions 7 "which are suitable for occupying the other areas 3e of unit tubes included in another solder module. These portions may then be The profile of the reactor plate 7 'then comprises, when crossing the plate transversely, first, for example, a portion 7 for reflecting sunlight to the first region 3a of a unit tube, then a portion 7 "for receiving the second area 3e of another unit tube, then again a portion 7 for reacting sunlight towards the first area of a unit tube, etc.
    At the area 3a of the unit tube 3, which contains the reactor part, a radiation-receiving part can also be arranged with a sun-catching surface, which is designed to convert solar energy into heat. Such a sun-catching surface may be formed as a light-absorbing layer 11 of suitable light-absorbing material. The light absorbing layer may be applied to the outer surface of a heat exchanger or heat transfer part, see Fig. 3. Alternatively, such a layer may be applied to or included in the heat insulating part Sa. Thus, the layer may be applied to or on an inner surface of the heat-insulating part Sa, such as on the shoulder-facing inner surface of the inner glass wall of a double-walled thermoset tube, or such a layer may be the outer, off-axis surface of the inner glass wall. The radiation-receiving part in each case consists of portions of the heat-transmitting part, of the heat-insulating part or of the inner wall of the thermotube.
    The heat generated by the solar collector surface can, if required, be transferred to the reactor part of the unit tube 3 via a heat transfer part 13a, here also referred to as heat exchanger, for example designed as shown in Figs. 3 and 4. This heat transfer part 13a has three heat transfer parts. surfaces adjoining: A) the unit pipe 3, B) metal pipes 17, which are connected to a distribution system for heating and / or cooling, respectively C) the heat-insulating part 5a.
    Thus, in this case, each of the first and second areas 3a, 3e of the unit tube 3 is surrounded by a heat transfer part 13a, 13e for cooling or heating a heat-carrying medium such as water or vice versa for the first and second areas of the unit tube to be able to be cooled or heated by the heat-carrying medium, see Figs. 3 and 4. Such a heat-transferring part 13a, 13e can be designed as a bent metal plate 15, for example of aluminum or copper, which comprises an outer part 150 for contact with and abutment. against the inwardly facing surface of the friend insulating part 5a, 5e and an inner part 15i for contact with and abutment against the outer surface of the respective area 3a, 3e of the unit tube 3. The curved plate then has a longitudinal bend 15b or deflection of 180 ° , which means that its inner part l5i and outer part l5o can be segments of concentric cylinders, so that these parts are parallel to each other. At the bent part 15b, longitudinal metal pipes 17, in which the heat-carrying medium flows, can be placed and then the metal pipes can lie within the curved part to provide good heat-conducting contact between the metal plate 15 and the metal pipes 17.
    In the embodiment according to f1g. 4 shows an embodiment with a curved plate 15, which has two bends 15b of 180 °, which extend parallel to each other and which when the plate 15 is arranged around a unit tube 3 are relatively close to each other. To keep the two metal tubes 17 in place inside the bent portions 15b, hooks 23 can be used, which are arranged at a certain distance from each other in the longitudinal direction of the plate 15 and the tubes 17.
    The reactor part and evaporator / condenser part of the unit tube 3 can be constructed, for example, as shown in the above-mentioned international patent application WO 2007 / 139476. The matrix is then arranged in the form of a "mat": Matrix mat The matrix 31 is clamped between a heat conducting metal mesh 39 and the unit tube 3 inner wall, see f1g. 2d. The metal in the mesh 39 may be, for example, copper or stainless steel. The matrix thus lies as a matrix mat against the inner wall of a pipe part 3a, 3e included in the unit pipe 3 and comprises holes 40 designed for efficient steam transport within the matrix 31. A channel 35 is created along the axis of the pipe part, in which channel 35 steam or gas can pass. In addition, transport of steam or gas to and from the matrix can take place via the holes 40 in the matrix mat and through the metal mesh 39.
    Two other possible embodiments of the reactor part 3 and the evaporator / condenser part of the unit tube 3 will now be described, in which the absorbent material, ie the matrix material, is arranged in strip form along the inner wall surface of the respective part 3a, 3e of the unit tube. Between the axially directed surfaces of the strips there are free spaces for the passage of steam from and to the material and to or from a central continuous channel 35.
    Matrix between metal washers Each of the two areas 3a, 3e of the unit tube 3 is filled with center-hole matrix washers 31, which are interspersed with center-hole heat-conducting metal washers 33, 34, for example of copper or stainless steel, see Fig. 2b. A first center-hollow metal washer 33 is placed at the bottom of a closed pipe part 3a, 3e at one end, followed by a center-hollow matrix washer 31 placed thereon and a second center-hollow metal washer 34 placed thereon. The second metal washer 34 comprises holes 37 in addition to a center hole 36, see fi g. 2b. These three washers 33, 31, 34 form a unit.
    Between each such unit a spacer tube, not shown, is placed to separate the units from each other and to allow the passage of steam between the units. The center holes 36 of each unit form the central through-channel 35, which extends along the axis of the pipe section 3a, 3e and into which steam or gas can pass. Steam or gas can also pass through the additional holes 37 located in the second metal washer 34 in each unit.
    Matrix in screw form The matrix 31 is clamped between a heat-conducting metal mesh 38 and the inner wall of the unit tube 3, see fi g. 2c. The metal in the mesh 38 may be, for example, copper or stainless steel. The matrix 31 and the metal mesh 38 extend in the form of a screw or helix along the inner wall of a pipe part 3a, 3e included in the unit pipe 3, so that a channel 35 is created along the axis of the pipe part, in which channel 35 steam or gas can pass. In addition, the pitch in the screw or helix is adjusted so that gaps are formed between each pitch revolution, whereby the passage of steam is also allowed through the screw or helix. Steam or gas can also be transported to and from the matrix 31 through the metal mesh 38.
    The procedures for charging and discharging the chemical heat pump component are the same as for previously described chemical heat pumps according to the hybrid principle with matrix design.
    An example of the use of the solar collector will now be described.
    Solar-powered system for supplying heat and heat to a house The system consists of the present thermal solar collector 51 comprising a chemical heat pump 3 as above, the house's ordinary heating / cooling system 53, a heat sink and an ice storage in a tank 55, see fi g. 6. In addition, the system may comprise a system 57 for the distribution of tap water and a swimming pool 59.
    In addition to what a traditional solar collector can handle, the present thermal solar collector, including a chemical heat pump, can also supply heat around the clock and also cooling, see Figs. 7a - 7d.
    I fi g. 7a and 7b thus show the function of the system on a typical winter day, when the system delivers heat to the house during the day and during the night, respectively. During the day, the solar collector 51 receives energy 9 from sunlight and the chemical heat pump 3 is also charged by heating its reactor part more than its evaporator / condenser part. During charging, heat is formed in the evaporator / condenser part, and this heat is transferred via its heat exchanger and the heat-carrying medium to the house's heating system 53 and possibly also its system 57 for domestic hot water. When the solar radiation has ceased, the chemical heat pump 3 is discharged and then the reactor part is heated. Heat from the reactor part is transported by means of its heat exchanger and the heat-carrying medium to the house's heating system.
    I fi g. 7c and 7d show the function on a typical summer day, when the system delivers cooling to the house during the day and during the night, respectively. During the day, the solar collector 51 receives energy from sunlight and the chemical heat pump 3 is also charged by heating its reactor part more than its evaporator / condenser part. During charging, heat is formed in the evaporator / condenser part, and this heat can be transferred via its heat exchanger and the heat-carrying medium to the housing system 57 for domestic hot water. When the solar radiation has ceased, the chemical heat pump and then the reactor part are discharged, while the evaporator / condenser part becomes colder. Cooled heat-carrying medium from the evaporator / condenser part is led to the house's cooling system 53.
    Advantages of the thermal solar collector described here comprising a chemical heat pump compared to a separate solar collector and separate chemical heat pump may include one or fl era of the following: 1. No heat pump is needed indoors. 2. The system can distribute heat and cooling through air instead of liquid. This leads to lower system costs and fewer operational disruptions. 3. The entire capacity of the chemical heat pump is used, when in the middle of the day it is necessary to receive the peak power from the sun, ie. when storage is needed most. When cooling is produced at night, it is produced, when it is easiest during the coldest time of the day and then with the entire capacity of the chemical heat pump, which gives a better cooling COP and that in both charging and discharging a smaller system is needed . A combined solar collector and chemical heat pump reduces the consumption of expensive materials.
    . Heat losses are reduced to a minimum when the solar energy does not need to be transported in a pipe system. With small heat losses, the system can be operated with higher temperatures on the heat sink, which means: i) Expensive parts of the pipe system can be removed because you no longer need to pump the hot solar water. ii) The lowering can be integrated in the solar collector, so the need for installation of cooling fins and boreholes can be reduced. iii) Low cost of required electrical energy during operation due to lower pump demand. iv) The extremely small losses further enable the system to be operated at a higher temperature.
    V) Quality cooling with ice production in summer. vi) Quality heat where the condenser produces useful domestic hot water. Instead of using preheating of tap water as today, direct heating of tap water can be achieved, which simplifies the system. vii) Quality protection in winter where for the first time heat can be produced around the clock even if it is minus degrees outdoors. No other accumulation of heat is needed. 7. The system can be freely dimensioned according to the end user's needs, from one solar collector to one thousand solar collectors for the apartment, villa, hotel, office or industry. The system is completely modular and only one type of end product needs to be manufactured.
