Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

The solar photovoltaic and absorption refrigerating unit-based heating device comprises an absorption refrigerating unit 1 and a heat collector 2.

The absorption refrigeration unit 1 comprises a generator 3, a condenser 4, an evaporator 5 and an absorber 6, as is conventional in the art.

There are two types of absorption refrigeration units, namely ammonia-water absorption type and lithium bromide-water absorption type, and correspondingly, the generator 3 is filled with an ammonia-water mixture or a lithium bromide-water mixture, namely a mixture of an absorbent and a refrigerant, wherein the refrigerant has a low boiling point relative to the absorbent.

The generator 3 is heated by a heat source 20 (waste heat ). The low boiling refrigerant liquid in the generator 3 evaporates and the high boiling absorbent liquid remains in the generator 3.

The refrigerant vapor enters the condenser 4 and is condensed into a refrigerant liquid by the cooling medium. Heat is released during condensation.

After the refrigerant liquid is introduced into the evaporator 5 by the throttling of the first throttle valve 15, the pressure is reduced and the refrigerant liquid is evaporated. In the evaporator 5, the refrigerant exchanges heat with the user side B through the heat exchanger 14 to supply cooling energy to the user side B, and the refrigerant absorbs heat to become refrigerant vapor.

The refrigerant vapor enters the absorber 6. The second throttle valve 16 is opened, the absorbent at the high mixing point in the generator 3 flows to the absorber 6, and through the throttling action of the second throttle valve 16, when the absorbent enters the absorber 6, the pressure is reduced and the absorbent is evaporated into gas, and the absorbent gas is mixed with the refrigerant gas, releases heat and forms mixed liquid.

The absorbent and refrigerant mixture liquid is pumped into the generator 3 by the action of the solution pump 17.

The absorption refrigeration unit 1 of the present example also includes a heat exchanger 13. The solution flowing from the generator 3 to the absorber 6 exchanges heat with the solution flowing from the absorber 6 to the generator 3 in the heat exchanger 13, thereby improving energy utilization.

Therefore, the absorption refrigerating unit can provide cold for the user side B.

The heat collector 2 comprises a heat collecting plate 8 and a heat collecting pipe 7, the heat collecting pipe 7 is fixed on the heat collecting plate 8, and in this example, the heat collecting pipe 7 is fixed on the heat collecting plate 8 by welding. The heat collecting plate 8 is disposed at the back of the photovoltaic panel 19 for cooling the photovoltaic panel 19, thereby ensuring the photoelectric conversion efficiency of the photovoltaic panel 19. The cooling water in the heat collecting tube 7 is heated, the temperature of the photovoltaic panel 19 is lowered, and both the heat collecting plate 8 and the heat collecting tube 7 have a heat conducting function. The photovoltaic panel 19 can provide electrical energy to the customer premises C.

The heat collecting pipe 7 is provided with a first water storage tank 9, and cooling water is stored in the first water storage tank 9 and used for supplying cooling water to the heat collecting pipe 7. The cooling water is introduced from a water inlet 10 provided on the first storage tank 9 and can be discharged from a water outlet 11 provided on the first storage tank 9.

The heat collecting tube 7 also extends far, and the heat collecting tube 7 extends into the absorber 6 and the condenser 4, thereby exchanging heat with the absorber 6 and the condenser 4. As described above, the absorber 6 and the condenser 4 both release heat, so that the cooling water in the heat collecting pipe 7 disposed therein is further heated.

In order to provide the heat exchange efficiency of the heat collecting pipe 7 with the absorber 6 and the condenser 4, the heat collecting pipe 7 extends in a zigzag mode in the absorber 6 and the condenser 4, so that the length of the heat collecting pipe 7 in the absorber 6 and the condenser 4 is prolonged, and the heat exchange efficiency is improved.

In this example, the heat collecting tube 7 extends into both the absorber 6 and the condenser 4, and utilizes the heat released from the absorber 6 and the condenser 4 to a large extent. In other ways, the heat collecting pipe 7 can extend only into the absorber 6 or only into the condenser 4.

The heat collecting pipe 7 forms a closed loop circulation pipeline, so that the cooling water in the heat collecting pipe 7 is circularly heated, and the temperature to which the cooling water is heated is easily controlled. Of course, in other embodiments, the heat collecting tube 7 may not be arranged in a closed loop, for example, in an open loop, and has an inlet and an outlet, and the cooling water flows through the heat collecting tube 7 only once after entering from the inlet, i.e., flows out from the outlet.

The heat collecting pipe 7 is provided with a water pump 18 for providing power for the circulation of cooling water.

The first water storage tank 9 is provided with a temperature measuring part 22, and the temperature measuring part 22 can be a mechanical thermometer or an electronic thermometer and is used for detecting the temperature of cooling water so as to discharge hot water from the water outlet 11 when a certain water temperature is reached. For example, in this example, when the water temperature in the first water tank 9 is set to 45 °, hot water is discharged from the water outlet 11, and the hot water can be temporarily stored in the second water tank 12 connected to the water outlet 11, and the user terminal a can be supplied with hot water when necessary. A valve 21 is arranged between the water outlet 11 and the second water storage tank 12 so as to control water outlet.

In this example, the water outlet 11 is provided on the first water storage tank 9, which is for facilitating the rapid discharge of hot water. In other embodiments, the water outlet 11 may also be disposed at other positions of the heat collecting tube 7.

In summary, the heating device based on the solar photovoltaic and absorption refrigerating unit of the present embodiment can not only cool the temperature of the photovoltaic panel 19 through the heat collecting tube 7 loaded with cooling water to improve the photoelectric conversion efficiency of the photovoltaic panel 19, but also provide hot water to the user terminal a. Moreover, the photovoltaic panel 19 can be used for providing electric energy for the user terminal C, and the absorption refrigeration unit 1 can be used for providing refrigeration capacity for the user terminal B, so that multiple benefits are achieved.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
