Abstract

The invention discloses an air conditioning system based on coupling of an air source heat pump and a composite solar heat collector. The system comprises a solar heat exchanger, an electric air conditioner compressor, an air conditioner pipeline, an in-vehicle evaporator, an in-vehicle condenser, an outdoor heat exchanger, a four-way reversing valve, a first electronic expansion valve, a second electronic expansion valve, a third electronic expansion valve, a first solenoid valve, a second solenoid valve, a third solenoid valve, a fourth solenoid valve, a liquid storage drying tank, an air blower, a gas-liquid separator, a PTC heater and a condensate fan. According to the air conditioning system, the solar heat exchanger is additionally arranged, the Fresnel condensation heat collector is used for collecting direct solar radiation and scattered energy and forming high-energy-density light beams, and the compound paraboloid condensation heat collector is used for tracking solar rays and gathering energy. When the air conditioner is used in a low-temperature environment, effective collection of energy can be achieved by adding the solar heat exchanger. And the defects of non-uniform heat distribution in the air, less energy and great influence of environmental temperature and territory are effectively overcome.

Description

Technical field: [0001] The invention relates to an air-conditioning system based on the coupling of an air-source heat pump and a composite solar heat collector and a working method thereof, belonging to the technical field of automobile air-conditioning and the technical field of solar heat utilization. Background technique: [0002] Air source heat pump air conditioning system is widely used in household air conditioning, shopping malls and industrial heating, and the technology is mature. In the new energy vehicle industry, especially the electric vehicle industry, the heat pump air-conditioning system is favored by the majority of automobile manufacturers for its advantages of low energy consumption, safe use, and high heating COP. [0003] The working principle of air source heat pump air-conditioning system heating is as follows: the low-temperature and low-pressure gaseous refrigerant is compressed by the compressor, and then the high-temperature and high-pressure ga...
