Abstract
The invention discloses a solar energy-assisted vapor compression heat pump dehumidification air-conditioning system, which relates to the field of compression heat pumps, including a solar heat collector, a heat collection circulation pump, a hot water circulation pump, a generator, a solution heat exchanger, an absorber, and a condenser , compressor, fluorine circuit four-way valve, solar reheater, outdoor heat exchanger, liquid receiver, subcooler, indoor heat exchanger, fluorine circuit three-way valve, dehumidification heat exchanger, fan, air duct, air Four-way valve: The fluorine circuit four-way valve can switch between cooling and heating modes according to different seasons. Through the coordinated switching of the air four-way valve and the fluorine circuit three-way valve, the air conditioning system can continuously output air that meets the indoor temperature and humidity requirements. Through the implementation of the present invention, the evaporation temperature of the wet load can be increased, not only the energy consumption ratio of the air-conditioning system can be improved by using solar energy in summer, but also the energy efficiency of heating can be improved by using air energy and solar energy at the same time in the heating mode in winter for air source heat pumps.
Description
technical field [0001] The invention relates to the field of compression heat pumps, in particular to a solar-assisted vapor compression heat pump dehumidification and air conditioning system. Background technique [0002] In the prior art, the vapor compression air-conditioning system is widely used in the market because of its small size, convenient energy use, and cooling and heating functions; A large amount of consumption will cause fluctuations in the power grid, making an urgent need for energy-saving improvements in vapor compression air-conditioning systems. [0003] The vapor compression air-conditioning system adopts a conventional coupling treatment method for heat and humidity loads. The evaporation temperature must be lower than the dew point temperature to achieve the effect of condensation and dehumidification to effectively handle the humidity load, which limits the performance improvement of the air conditioning system; for areas with abundant solar energy ...
