Abstract

The invention provides a system and method for preventing an air source heat pump water heater from frosting by using solid dehumidification. In the method, a heat exchanger with a solid drying agent coating is used for preprocessing water in moist air, and therefore the water in the moist air is prevented from frosting on the surface of an evaporator. According to the system and method, the air of an inlet of the evaporator is dehumidified by means of the solid drying agent coating, so that the frosting problem of the heat pump water heater is resolved, and heating performance of the heat pump water heater is enhanced. When the water absorbed by solid adsorbing agents reaches a limitation, water in the solid adsorbing agents is desorbed by means of heat released by condensation of heat pump work media, at this time, circulation air with desorbed high-temperature moisture has heat exchange and congeals on the surface of the evaporator, the evaporator recycles the heat released in a condenser, and regeneration efficiency of a heat pump is improved.

Description

The system and method for solid dehumidifying prevention air source hot pump water heater frosting
Technical field
