Problems solved by technology

The above research results also show that the solar heat pump system has good environmental protection and energy saving effects and development potential. Most of the previous research on PV / T used water or air as the heat transfer medium. Due to the high temperature of water or air, the cooling effect It is not ideal, and the photoelectric conversion efficiency of the battery has been difficult to reach a high level; in addition, the vapor compression heat pump system must have an external power supply during operation, which limits its scope of use to a certain extent.
[0003] Among the existing solar heat pump patents, such as solar heat pump air conditioning system and solar + air source heat pump air conditioning system 02117298.6, solar heat pump cooling and heating air conditioner 02219389.8, and solar heat pump cooling and heating system 02239555.5 generally only use the long-wave part of solar energy, and fail to realize solar energy. Comprehensive utilization of photoelectricity and light and heat

Embodiment Construction

[0016]As shown in Figure 1, the present invention consists of a compressor 1, a water-cooled condenser 2, an air-cooled condenser 3, a throttling element 4, a PV / T evaporator 5, an air-cooled evaporator 6, and a photovoltaic control system 7. The device 2 and the air-cooled condenser 3 are connected in parallel, which are respectively used as heat exchangers for making domestic hot water or room heating. The PV / T evaporator 5 and the air-cooled evaporator 6 are connected in parallel. When the solar radiation is insufficient or there is no When the sun radiates, it absorbs heat from the air as a supplement to the PV / T evaporator 5; the output of the PV / T evaporator 5 is connected to the photovoltaic control system 7, and the PV / T evaporator 5 converts part of the received solar energy directly into Part of the electric energy is absorbed by the refrigerant in the form of heat, and part of it is lost in the air. After the refrigerant at the outlet of the PV / T evaporator 5 absorbs...

Abstract

A photovoltaic solar energy heat pump is prepared as converting partial received solar radiation to be electric energy directly by PV / T evaporator and absorbing another partial solar radiation by refrigerant working media in heat energy mode, making refrigeration working media at outlet of PV / T evaporator to be overheat state after it is absorbed with heat energy, sending it into compressor to raise its pressure and temperature and sending it to condenser for releasing heat then sending it to throttle element for changing it to be two-phase mixture with low pressure and low temperature and finally entering PV / T evaporator again.

Description

technical field [0001] The invention relates to a photovoltaic solar energy heat pump multifunctional integrated system (PV / T SolarAssisted Heat Pump, PV / T-SAHP), which belongs to the field of solar energy utilization. Background technique [0002] The use of solar heat pumps can reduce the proportion of conventional energy used in building energy consumption, and has extremely far-reaching significance for seeking solutions to the two major social problems of energy and the environment.
