Problems solved by technology

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.

Abstract

The invention provides a drying system, an air conditioner and a work mode switch method. The drying system comprises an outdoor heat exchanger, a first indoor heat exchanger, a second indoor heat exchanger, a compressor, a three-way electromagnetic valve and a controller. The three-way electromagnetic valve is provided with three ports at the first end, second end and third end, wherein the first end is connected to the compressor through a four-way valve, the second end is connected to the outdoor heat exchanger, and the third end is connected to the first indoor heat exchanger. The controller is connected to the three-way electromagnetic valve and used for switching the three ports according to a received mode adjustment instruction to adjust the work modes of the air conditioner, and the work modes include a pre-heating mode, a temperature-control mode and a drying and dehumidification mode. The technical scheme replaces the scheme in the correlation technique that air is pre-heated in an electric heating mode, so that energy consumption is reduced, automatic control over drying of a heat pump is realized, energy is saved greatly, and emission is reduced greatly.

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...
