Abstract

The invention discloses a new type of solar energy frost-free air source heat pump system, which includes a photothermal photoelectric system, a solution circulation system, and a heat pump system; the system uses a solution dehumidification system to realize the frost-free and efficient operation of the heat pump in winter, and uses the photothermal system to improve The heat source utilization rate of the solution regeneration uses the photoelectric system to solve the energy consumption problem of the load in the system. At the same time, the system can produce hot water in both winter and summer and can be used for indoor adjustment of the air conditioner terminal. This system solves the problem of frosting of the outdoor heat exchanger of the traditional air source heat pump in winter and the regeneration of the dehumidification solution, makes full use of solar energy, and embodies the concept of sustainable air conditioning.

Description

technical field [0001] The invention belongs to the field of solar energy and air source heat pumps, in particular to a novel solar energy frost-free air source heat pump system. Background technique [0002] At present, the traditional methods for frosting mainly include electric heating defrosting, hot gas bypass defrosting and reverse cycle defrosting. Although electric defrosting is a simple and operable method, its efficiency is not high. Reverse cycle defrosting requires four-way valve reversing, which reduces the indoor temperature and affects the comfort of the human body. Although hot gas bypass defrosting does not need to absorb indoor heat, it can provide a small amount of heat at the same time, avoiding the feeling of cold wind during defrosting, and the temperature of the water supply drops slowly, but if the defrosting time is too long, the indoor temperature will drop. In response to the above problems, a large number of scholars have studied the material of ...
