Abstract

The invention relates to a heat pump air conditioner with adjustable humidity, belonging to the technical filed of refrigeration. The heat pump air conditioner comprises a compression heat pump system and a rotating wheel dehumidifying system, which are connected with each other. The rotating wheel dehumidifying system comprises a belt or gear, a dehumidifying rotating wheel, a heater, a heat regenerator, an outdoor blower, a motor, and an indoor blower, wherein the motor is connected with the dehumidifying rotating wheel via the belt or gear, the dehumidifying rotating wheel is respectively connected with the heater and heat regenerator in fresh air region via air pipes, the heat regenerator is connected with an indoor heat exchanger at fresh air side with an air pipe, the indoor heat exchanger is connected with the indoor blower, an outdoor heat exchanger subzone is connected with the heater via an air pipe, and the other side of the outdoor heat exchanger subzone is connected with an outdoor heat exchanger of the compression heat pump system via an air pipe. The invention can effectively utilize condensation of air conditioner to remove heat, and is an environmentally-friendly and energy-saving refrigeration unit with the advantages of simple structure, automatic operation, and no environmental pollution.

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 ...
