It is a further optimization and improvement of heat pump technology and has important significance for energy conservation and emission reduction. Background Art

[0002] With the rapid advancement of urbanization and in-depth structural adjustments, the carbon emissions generated by heating and its proportion of the total carbon emissions of the whole society have further increased. In order to improve the environment and reduce pollution, the country advocates the use of energy-saving products. In promoting clean heating in winter in northern my country, reducing coal-fired pollution, and improving air quality, air source heat pumps are a very effective alternative. Heat pumps are widely used because they can provide cooling in summer, heat in winter, and are easy to operate.

[0003] The common household heat pump heating systems on the market now have high initial investment costs and high operating and maintenance costs, making it difficult to achieve widespread popularization. In addition, due to the limitations of the installation environment, common heat pump systems are not suitable for use in rural areas with scattered households. However, there are few high-rise buildings in rural areas, and there are sufficient resources such as photovoltaics, and there is ample installation space. Traditional batteries have their advantages, but if the monomer is too large, there will be safety hazards.

[0004] The present invention proposes further improvements and innovations for the heat pump system. Both the indoor unit and the outdoor unit use direct radiation heat exchangers; the coating of the outdoor unit is modified to improve the ability to absorb solar energy and increase the utilization rate of energy; the defrost belt is powered by photovoltaic panels. The power unit is small in size and is safer to be placed outdoors. In extremely cold weather, it helps to increase the temperature of the outdoor evaporation plate and the heating temperature. The hot smoke generated during the use of household appliances such as rural indoor gas water heaters contains a large amount of waste heat, which is transferred to the evaporation plate through the flue to increase the temperature of the evaporation plate and fully utilize the heat. The system has only one moving part, a very simple structure, and low operating and maintenance costs, making it suitable for decentralized heating in rural areas.

[0005] In summary, in order to solve the above-mentioned problems in the implementation of air source heat pumps in rural areas, further improvements and innovations are needed on the outdoor evaporation plates and defrost belt applications of existing heat pumps. Summary of the invention

Finally, black paint and copper powder are mixed, and metal blocks are adhered to the surface to enhance the ability to absorb solar energy; the defrost belt is powered by a photovoltaic panel, which makes the power unit small in size and safer to place outdoors. In extremely cold weather, it helps to increase the temperature of the outdoor evaporation plate and the heating temperature; in addition, the system transfers the heat generated by indoor smoke-producing appliances to the outdoor evaporation plate through the flue, which helps to increase the temperature of the outdoor evaporation plate and realizes full utilization of heat. The system improves the utilization rate of solar energy, reduces safety hazards, makes full use of the waste heat in hot smoke, and realizes stable operation of the system through changes.

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0018] Embodiment 1:

[0019] like Figure 1 As shown, the present invention provides a direct radiation adaptive heat pump system, including a compressor 3, an outdoor evaporation plate 4, an indoor heat radiation plate 5 and a capillary tube 6.

[0020] The surface coating of the outdoor evaporation plate 4 is a black coating 13, and metal powder is mixed into the coating, and a metal block 14 is adhered to the surface, which is designed to be an uneven surface;

[0021] During normal heating in winter, only the compressor is turned on. After the refrigerant is compressed by the compressor 3 into a high-temperature and high-pressure gas refrigerant, it enters the indoor heat radiation plate 5 for condensation and heat release for heating. The condensed low-temperature and high-pressure refrigerant enters the capillary 6 for throttling into a low-temperature and low-pressure refrigerant, and then enters the outdoor evaporation plate 4 for heat absorption. The heat-absorbing high-temperature and low-pressure refrigerant returns to the compressor 3 for further compression.

[0022] Embodiment 2:

[0023] When defrosting is required, the outdoor evaporation plate 4 is first defrosted. At this time, the defrost belt 7 switch is turned on, the compressor is turned off, and the outdoor evaporation plate 4 stops running. There is a defrost belt 7 on the back of the evaporation plate. The defrost belt 7 uses a photovoltaic panel 10 to convert light energy into electrical energy through a photovoltaic inverter 11 to achieve a defrosting effect. After defrosting is completed, the defrost belt 7 is turned off. Then heating can be resumed.

[0024] Embodiment 3:

[0025] When the temperature in winter is below -15°C, the low-temperature heating mode is used, that is, the compressor is turned on, the heat pump system is started, and the defrost belt 7 is turned on to assist in increasing the temperature of the outdoor evaporation plate 4 in extremely cold weather, drive the heat pump system to operate, and increase the heating temperature.

[0026] Embodiment 4:

[0027] When the indoor smoke-generating appliance 16 is in use, hot smoke is generated during use. Under normal heating conditions, the residual heat in the hot smoke is transferred to the outdoor evaporation plate 4 through the flue 17, which helps to increase the temperature of the outdoor evaporation plate 7, helps the system to operate normally, and improves the heat exchange efficiency.
