Solar-assisted steam compression heat pump dehumidification air-conditioning system

Abstract

The invention discloses a solar-assisted steam compression heat pump dehumidification air-conditioning system, and relates to the field of compression heat pumps. The system comprises a solar heat collector, a heat collection circulating pump, a hot water circulating pump, a generator, a solution heat exchanger, an absorber, a condenser, a compressor, a fluorine path four-way valve, a solar reheater, an outdoor heat exchanger, a liquid storage device, a subcooler, an indoor heat exchanger, a fluorine path three-way valve, a dehumidification heat exchanger, a fan, an air duct and an air four-way valve, the fluorine path four-way valve can switch a refrigerating mode and a heating mode according to different seasons, and the air-conditioning system continuously outputs air meeting indoor temperature and humidity requirements through matched switching of the air four-way valve and the fluorine path three-way valve. Through the implementation of the air-conditioning system, the evaporation temperature for treating the wet load can be increased, the electric power consumption ratio of refrigeration of the air-conditioning system in summer can be increased through solar energy, and the heating energy efficiency can be better than that of an air source heat pump through air energy and solar energy at the same time in the heating mode in winter.

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 ...
