Problems solved by technology

The fundamental condition for air-conditioning condensation is that the surface temperature of the indoor air-conditioning heat exchanger is lower than the dew point temperature of the indoor air. However, these anti-condensation control methods for air-conditioning do not fundamentally solve the problem, but only some control methods to delay air-conditioning condensation. Does not really realize the anti-condensation of the air conditioner

Abstract

The invention provides an anti-condensation air conditioner controlling method and device as well as an air conditioner. The anti-condensation air conditioner controlling method comprises the steps of measuring the temperature and the humidity of an indoor air return position and the surface temperature of an indoor heat exchanger after refrigeration operation of the air conditioner is detected; calculating the dew point temperature of indoor air according to the temperature and the humidity of the indoor air return position; calculating the temperature difference between the surface temperature of the indoor heat exchanger and the dew point temperature of the indoor air; and comparing the temperature difference with a preset temperature difference and controlling a normal operation throttling device and an anti-condensation throttling device of the air conditioner according to a comparison result. According to the method, the flow of a refrigerant entering the indoor heat exchanger side is controlled by controlling the anti-condensation throttling device of the air conditioner, so that the surface temperature of the indoor heat exchanger is controlled to be higher than the dew point temperature of the indoor air all along, and the anti-condensation purpose is achieved.

Description

technical field [0001] The invention relates to an air conditioner control technology, in particular to an anti-condensation air conditioner control method, an air conditioner control device and an air conditioner. Background technique [0002] The environment in which the air conditioner is used is getting worse and worse. In particular, the air conditioner is prone to condensation when cooling in a low-humidity environment. There are many reasons for condensation, such as evaporator bias, overcooling, etc. At present, there are many anti-condensation methods for air conditioners on the market, such as reducing the operating frequency of the system, adding electric heating devices, and pasting flannelettes. The fundamental condition for air-conditioning condensation is that the surface temperature of the indoor air-conditioning heat exchanger is lower than the dew point temperature of the indoor air. However, these anti-condensation control methods for air-conditioning do ...
