DETAILED DESCRIPTION

[0024] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] As a new energy-saving and environmentally friendly technology with great development and application potential for high-efficiency energy utilization, air energy heat pumps are of great practical value. Air energy heating and hot water systems are becoming increasingly popular, and more and more families have a full set of equipment. Exploring whether there are new energy sources that can replace air energy as a source of energy for heat pumps is a key development direction in the field of heat pump system technology. At present, solar photovoltaic power generation is one of the common new energy sources and can be considered as a source of energy for heat pumps. However, the surface temperature of photovoltaic panels is too high after being exposed to the sun, causing deformation and damage to the material, which directly affects the service life of the heat pump system.

[0026] In order to solve the above problems, this embodiment provides a solar energy and heat pump coupling system, which uses solar energy as the main source of heat absorbed by the heat pump, and can also reduce the surface temperature of the photovoltaic panel and extend the service life of the photovoltaic panel.

[0027] like Figure 1 As shown, the solar energy and heat pump coupling system specifically includes a compressor 1, a condenser 3 and a photovoltaic panel assembly 6. The compressor 1 is a mechanical device for increasing the pressure of gas or steam, and increases its pressure by reducing the volume of the gas. The compressor 1 has an exhaust port 11 and a return port 12. The pressurized gas of the compressor 1 is output from the exhaust port 11, and the return port 12 returns the gas after passing through the photovoltaic panel assembly 6 to the compressor 1 for compression.

[0028] The first valve body 2 includes a first valve port 21, a second valve port 22, a third valve port 23 and a fourth valve port 24; in the present embodiment, the first valve body 2 is a four-way valve; wherein the first valve port 21 is connected to the second valve port 22, the third valve port 23 is connected to the fourth valve port 24, the exhaust port 11 is connected to the first valve port 21 through a pipeline, the second valve port 22 is connected to the condenser 3, the third valve port 23 is connected to the return air port 12 through a pipeline, and the fourth valve port 24 is connected to the photovoltaic panel assembly 6.

[0029] The condenser 3 has a refrigerant inlet 31 and a refrigerant outlet 32. The refrigerant inlet 31 is connected to the second valve port 22. The compressed high-temperature and high-pressure refrigerant gas is introduced into the condenser 3 to release the heat of the compressed high-temperature and high-pressure refrigerant gas and condense it into a high-pressure liquid. The refrigerant outlet 32 ​​releases the high-pressure liquid after the temperature is released. During this period, the heat is released into the water to heat the water. The condenser 3 also has a water outlet 33 and a water return port 34. The water outlet 33 flows the heated water in the condenser 3 to the water tank for user use, or the water tank can be directly connected to the water return port 34 through a water pump, which is used to pump the water in the water tank into the condenser 3 through the water return port 34.

[0030] like Figure 1 As shown, the refrigerant outlet end 32 of the condenser 3 can be directly connected to the pipeline of the photovoltaic panel assembly 6. The photovoltaic panel assembly 6 includes a photovoltaic panel and a pipeline arranged on the back of the photovoltaic panel. The direction of the pipeline on the back of the photovoltaic panel can be designed according to actual conditions. The pipeline has a pipeline inlet end 61 and a pipeline outlet end 62. The refrigerant outlet end 32 of the condenser 3 can directly flow the refrigerant liquid after the release temperature into the pipeline on the back of the photovoltaic panel through the pipeline inlet end 61. The refrigerant liquid in the pipeline absorbs the surface temperature of the photovoltaic panel by heat exchange, reduces the surface temperature of the photovoltaic panel, and avoids the situation where the photovoltaic panel is deformed and damaged due to excessive surface temperature. The photovoltaic panel assembly 6 acts as an evaporator, absorbing the heat generated when sunlight irradiates the photovoltaic panel, converting the refrigerant in the liquid state into the refrigerant in the gaseous state. The refrigerant in the gaseous state is compressed into a high-temperature and high-pressure gas by the compressor 1 and then transported to the condenser 3. The condenser 3 converts the high-temperature and high-pressure gaseous refrigerant into a high-pressure liquid and releases the heat into the water. The heated water is provided to the user.

[0031] The refrigerant in the pipeline on the back of the photovoltaic panel absorbs the heat from the surface of the photovoltaic panel, causing the liquid refrigerant to evaporate into gas. The gaseous refrigerant flows through the pipeline outlet end 62 of the pipeline through the fourth valve port 24 and the third valve port 23 in sequence and flows back to the compressor 1 for pressurization processing.

[0032] In one embodiment, the system further comprises a liquid storage tank 4 and a throttling mechanism, such as Figure 2As shown, the refrigerant outlet end 32 can be connected to the pipeline of the photovoltaic panel assembly 6 after passing through the liquid storage tank 4 and the throttling mechanism.

[0033] The liquid storage tank 4 is arranged between the condenser 3 and the photovoltaic panel assembly 6, and is used to store the refrigerant liquid flowing out of the refrigerant outlet end 32; and a throttling mechanism is arranged between the liquid storage tank 4 and the photovoltaic panel assembly 6, and the throttling mechanism can be an electronic expansion valve 5, and the electronic expansion valve 5 has a fifth valve port 51 and a sixth valve port 52, the fifth valve port 51 is connected to the liquid storage outlet end of the liquid storage tank 4, and the sixth valve port 52 is connected to the pipeline inlet end 61 of the photovoltaic panel assembly 6. The electronic expansion valve 5 is used to adjust the refrigerant flow entering the photovoltaic panel assembly 6. The larger the refrigerant flow, the more obvious the cooling effect on the photovoltaic panel assembly 6; at the same time, the electronic expansion valve 5 can also convert the refrigerant in the system from a high-pressure liquid state to a low-pressure liquid state to enter the photovoltaic panel assembly 6, which plays a throttling role.

[0034] In order to realize automatic control, the system also includes a controller, which is electrically connected to the electronic expansion valve 5. The controller can control the switch state of the fifth valve port 51, the switch state of the sixth valve port 52, and the size of the refrigerant flow rate; in addition, the controller can also be electrically connected to the first valve body 2 to control the switch state of each valve port of the first valve body 2. When the controller controls each valve port of each valve body to be in an open state, the system pipelines are connected, so that the refrigerant flows between the compressor 1, the condenser 3, and the photovoltaic panel assembly 6 to form a heating circuit.

[0035] The controller can also be connected to the compressor 1 and the condenser 3 to control the working status of the compressor 1 and the condenser 3. At the same time, the controller can also be electrically connected to the photovoltaic panel assembly 6. The photovoltaic panel converts light energy into electrical energy to provide power to the controller to maintain normal operation of the controller.

[0036] This embodiment proposes a solar energy and heat pump coupling system, in which the photovoltaic panel assembly 6 can generate electricity and also serve as an evaporator to absorb the heat generated when sunlight shines on the photovoltaic panel. After passing through the compressor 1, the heat is transported to the condenser 3, and the condenser 3 releases the heat into the water, and the heated water is provided to the user. Therefore, the heat pump unit except the photovoltaic panel will have a smaller volume, reducing the floor space of the unit, and facilitating installation and maintenance. At the same time, the surface temperature of the photovoltaic panel can be reduced, and the deformation of the material of the photovoltaic panel due to the excessively high surface temperature can be avoided, which can affect the service life of the photovoltaic panel. It can also increase the power generation and effectively improve the power generation efficiency.
