Description

technical field [0001] The invention relates to an air conditioner in the technical field of refrigeration, in particular to a heat pump air conditioner with adjustable humidity. Background technique [0002] The rotary dehumidification / humidification technology using low-grade heat sources conforms to the general trend of the current coordinated development of energy and environment. The dehumidification of the solid rotor can use the condensed waste heat to drive the drying rotor to remove the latent heat load in the air conditioner, and the electric-driven vapor compression refrigeration system can remove the sensible heat load in the air, which can greatly improve the efficiency of the electric air conditioner, and can play a role in the tense trend of power supply. Mitigation. In addition, the dehumidification of the rotary wheel reduces the use of chlorofluorocarbon refrigerants, and there is no CFCS problem and no greenhouse effect. It is an environmentally friendly ...
