Problems solved by technology

However, there is a need for dehumidification in a low-temperature and high-humidity environment. When the cooling mode is turned on in this environment, the evaporator is prone to frost and cause shutdowns and other failures
However, when the dehumidification mode is turned on in a low-temperature and high-humidity environment, the evaporation temperature is also low due to the low dew point temperature in the low-temperature environment, so it is easy to have anti-freezing protection of the evaporator, resulting in system oscillation, temperature field fluctuations, and dehumidification. not effectively

Abstract

The invention provides an air conditioner control method which comprises the steps of under a dehumidification mode, detecting the temperature of a heat exchange pipe of the air conditioner; judging whether the temperature is greater than a first preset threshold value; when the temperature is greater than the first preset threshold value, controlling the air conditioner to run under a normal dehumidification mode; when the temperature is smaller than the first preset threshold value, increasing the temperature of the heat exchange pipe by adjusting the running frequency of a compressor of the air conditioner and/or the rotating speed of an indoor fan so as to ensure that the air conditioner runs under the dehumidification mode efficiently and stably. The invention also provides an adaptive dehumidification control system and an air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioning and refrigeration, in particular to an air conditioner control method and system, and an air conditioner. Background technique [0002] Existing air conditioners all use the dehumidification function as a basic function. But in fact, the dehumidification function is basically marginalized, and the dehumidification function is basically included and replaced by the cooling function, so that the dehumidification function becomes a functional display. However, there is a need for dehumidification in a low-temperature and high-humidity environment. When the cooling mode is turned on in this environment, the evaporator is prone to frost and cause shutdowns and other failures. However, when the dehumidification mode is turned on in a low-temperature and high-humidity environment, the evaporation temperature is also low due to the low dew point temperature in the low-temperature environment, so...
