Drying system, air conditioner and working mode switching method

Abstract

The present invention proposes a drying system, an air conditioner and a working mode switching method, wherein the drying system includes: an outdoor heat exchanger, a first indoor heat exchanger, a second indoor heat exchanger and a compressor ;Three-way solenoid valve, the three-way solenoid valve has three ports of the first end, the second end and the third end, wherein, the first end is connected to the compressor through the four-way valve, and the second end is connected to the outdoor heat exchanger, The third end is connected to the first indoor heat exchanger; the controller, connected to the three-way solenoid valve, is used to switch between the three ports according to the received mode adjustment command, so as to adjust the working mode of the air conditioner, wherein , The working modes include preheating mode, temperature control mode and drying and dehumidification mode. Through the above technical solution, it replaces the solution of air preheating by electric heating in the related art, saves energy consumption, realizes the automatic control of heat pump drying, and can greatly save energy and reduce emission.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a drying system, an air conditioner and a working mode switching method. Background technique [0002] At present, the general air-conditioning drying system uses electric heating to preheat the air. This method of preheating consumes a lot of energy, which is inconsistent with the current concept of energy saving and emission reduction. Therefore, in general, in order to achieve energy saving and emission reduction, the drying system is used to preheat the air. [0003] However, the general drying system cannot automatically control the temperature of air preheating, let alone automatically dry and dehumidify the air. [0004] Therefore, how to save energy and automatically control heat pump drying has become an urgent problem to be solved. Contents of the invention [0005] Based on the above problems, the present invention proposes a new technical solution...
