Thermostat dehumidification control method of air conditioner

Abstract

The invention discloses a thermostat dehumidification control method of an air conditioner. The air conditioner comprises a compressor, a condenser, an electronic expansion valve, an evaporator, a four-way reversing valve, an outdoor fan, an indoor fan, an indoor temperature sensor, an indoor humidity sensor and an outdoor temperature sensor; and the evaporator is divided into a heating section and a dehumidifying section by a dehumidifying electromagnetic valve. The dehumidifying operating mode of the air conditioner is divided into a cold room dehumidification control mode and a thermostat dehumidification control mode according to the difference between the temperature detected by the indoor temperature sensor and the temperature set by a remote controller. When the air conditioner is in the thermostat dehumidification control mode, the thermostat dehumidification control mode is further subdivided into three control areas according to the relative humidity detected by the indoor temperature sensor, thus the purposes of reducing the indoor temperature and keeping the temperature constant are achieved by controlling the frequency of the compressor, the rotation speed of the outdoor fan and various valves, and a conformable indoor environment is provided for the user.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a constant temperature dehumidification control method for an air conditioner which keeps the indoor ambient temperature constant and makes the indoor air reach a comfortable humidity during the dehumidification period. Background technique [0002] The dehumidification function of the existing air conditioner is basically the same as the principle of the ordinary cooling mode. It obtains the dehumidification capacity through the operation of the indoor fan in the breeze. When the room temperature is low, it will bring discomfort to the user. [0003] In order to achieve the purpose of dehumidification without cooling, some existing air conditioners adopt the control mode of turning on the electric heating to compensate the cooling capacity during dehumidification, and can adjust the opening or closing of the auxiliary electric heating in time according to the change of ...

AI Technical Summary

Problems solved by technology

[0004] Although the existing dehumidification control method will not increase the production cost, but because the electric efficiency of the auxiliary electric heating is very low, the energy efficiency ratio of the air conditioner is low and the energy consumption is high, and this method will cause the indoor environment temperature to fluctuate greatly. Can not achieve the real constant temperature dehumidification effect
