Problems solved by technology

The utilization rate of solar energy in photovoltaic power generation cannot reach 100%. A large part of the solar energy is converted into heat energy. This part of the heat will be generated by the solar panel. If this part of the heat is not taken away in time, the solar panel will generate temperature rise. The photoelectric conversion efficiency of solar panels will decrease with the increase of temperature.

Abstract

The invention provides a heat pump system and a control method thereof. The heat pump system comprises a compressor, a first throttling device, a first evaporator, a second throttling device, a detection device, a first control device and a photovoltaic power generation device. The photovoltaic power generation device comprises a second evaporator and a solar cell panel. The first end of the second evaporator is connected with the second throttling device. The second end of the second evaporator is connected with an air return port of the compressor. The solar cell panel is connected with the second evaporator. The second evaporator is used for cooling the solar cell panel. According to the heat pump system, electric quantity generated by the solar cell panel can be directly provided for the heat pump system, energy conservation and environment protection are achieved, the solar cell panel is cooled through a lower-temperature refrigerant, and air return temperature and pressure of the refrigerant are detected through the detection device, and the first control device controls the first throttling device and the second throttling device to be opened or closed according to the air return pressure and temperature.

Description

technical field [0001] The invention relates to the field of heat pump systems, in particular to a heat pump system and a control method for the heat pump system. Background technique [0002] At present, with the energy crisis and environmental protection issues, more and more attention has been paid to energy conservation. With the development of people's experience in modern society, people's requirements for quality of life are also getting higher and higher. [0003] Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. The key component of this technology is a solar panel. The utilization rate of solar energy in photovoltaic power generation cannot reach 100%, and a large part of the solar energy is converted into heat energy. This part of the heat will be heated by the solar panels. If this part of the heat is not taken away in time, the solar panels will ...
