The light energy conversion device 11 is a solar energy device, such as a solar collector. The heat energy conversion device 101 is a multifunctional device based on absorption refrigeration and heating technology, which can provide refrigeration, heating and hot water at the same time, such as an absorption cooling and heating all-in-one machine.

[0036] Central heating is the main form of heating in northern China, and a large number of pipelines have been laid in cities. However, with the rapid development of urbanization, the heat transmission capacity of the heating network is insufficient, and the expansion of the heating network involves large investments and difficult construction.

[0037] In an embodiment of the present invention, a medium circulation network 30 and / or a light energy conversion device 11 are used to drive a heat energy conversion device 101 to operate. In the heating season, the heat energy conversion device 101 is used to heat a heat exchange medium in the medium circulation network 30 to increase the heat transfer capacity. Alternatively, in the cooling season, the heat energy conversion device 101 is used to cool a heat exchange medium in the medium circulation network 30 to increase the cooling capacity. The heat energy conversion device 101 can be used to heat water supplied by an external water supply device to provide heated water to users.

[0038] The thermal energy conversion device 101 is connected to the light energy conversion device 11.

[0044] Among them, the thermal energy conversion component is connected to the photoelectric conversion device 11, the photoelectric conversion device 11 collects solar energy, uses solar energy to heat the heat exchange medium, and supplies the heated heat exchange medium to the thermal energy conversion component. The thermal energy conversion component uses the thermal energy of the heat exchange medium to drive the entire thermal energy conversion device 101 to work, that is, to drive the refrigeration component and the heating component to work. The refrigeration component cools the heat exchange medium, and the heating component generates heat to heat water or heat exchange medium.

[0045] In the above scheme, the heat exchange medium is heated or cooled, the water is heated, and the clean energy solar energy is fully utilized through the cooperation of the refrigeration components, the heating components and the heat energy conversion components, which improves the utilization rate and reduces the cost of use.

[0048] Among them, in the heating season, the generator 1011 is connected in series with the evaporator 1012 to construct a heat energy conversion component, and the absorber 1014 is connected in series with the condenser 1013 to construct a heating component; in the cooling season, the generator 1011 is constructed as a heat energy conversion component, the evaporator 1012 is constructed as a cooling component, and the absorber 1014 is connected in series with the condenser 1013 to construct a heating component.

[0049] In the above scheme, through the cooperation of the generator 1011, the evaporator 1012, the absorber 1014 and the condenser 1013, the function of the thermal energy conversion device 101 is fully exerted, and each part works in full coordination to provide a variety of cooperation modes, thereby adapting to a variety of needs and improving applicability.

[0050] Specifically, in the heating season, the generator 1011 and the evaporator 1012 are connected in series to fully utilize the thermal energy to drive the absorber 1014 and the condenser 1013 to work, and the absorber 1014 and the condenser 1013 are connected in series to heat the heat exchange medium; in the cooling season, the generator 1011 fully utilizes the thermal energy to drive the evaporator 1012, the absorber 1014 and the condenser 1013 to work, the evaporator 1012 is connected to the medium circulation pipeline 30 to cool the heat exchange medium, and the absorber 1014 and the condenser 1013 heat the water supplied by the external water supply device.

[0053] Among them, the heat source 1 can be a heating boiler or other heating device, and the heat exchange medium circulates in the first water supply pipe 31 and the first return water pipe 32. The heat exchange medium exchanges heat with the heat source 1 at the position of the first heat exchanger 2, and the temperature of the heat exchange medium increases. The heat exchange medium circulates in the second water supply pipe 33 and the second return water pipe 34, and at the position of the second heat exchanger 5, the heat exchange media in the two cycles exchange heat.

[0054] In the above scheme, by setting the first heat exchanger 2 and the second heat exchanger 5, the first water supply pipe 31, the first return pipe 32, the second water supply pipe 33 and the second return pipe 34 cooperate with each other, and multiple pipe networks are formed, which facilitates operation, improves safety, and facilitates operation.

[0055] Specifically, there may be more heat exchangers, such as a third heat exchanger 25, a fourth heat exchanger, etc., with similar effects, which will not be described in detail here.
