Anti-condensation control method and device for air conditioner

Abstract

The invention provides an anti-condensation control method and device for an air conditioner. The control method comprises the steps that after it is detected that the air conditioner is in a refrigeration mode, the temperature and the relative humidity of the inner environment where an air conditioner indoor unit is located and the heat exchanger coiler temperature of the indoor unit are detected; the dew point temperature of the indoor environment where the indoor unit is located is calculated according to the indoor environment temperature and the indoor environment relative humidity; if the indoor environment temperature is larger than or equal to the indoor environment temperature preset threshold value, the indoor environment relative humidity is larger than or equal to the indoor environment relative humidity preset threshold value and the heat exchanger coil temperature of the indoor unit is smaller than the indoor environment dew point temperature, whether the first anti-condensation mode or the second anti-condensation mode of the air conditioner is started is determined according to the comparison result of the difference value of the heat exchanger coil temperature and the indoor environment dew point temperature of the indoor unit and the preset temperature difference value. By the adoption of the anti-condensation control method and device, the anti-condensation control accuracy of the air conditioner is improved, and the air conditioner is prevented from generating condensation.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to an anti-condensation control method and device for an air conditioner. Background technique [0002] When the air conditioner is running in cooling mode, if the air conditioner is in a high-temperature and high-humidity environment, the water vapor in the air is likely to condense on the air outlet of the indoor unit of the air conditioner or the air deflector to produce water droplets, resulting in water The beads drip or blow out from the air outlet, which damages the user's indoor environment and affects the user's experience. [0003] The existing method is generally to paste flannelette on the wind deflector or paste an electric heating sheet on the air outlet. The scheme of pasting flannelette on the wind deflector can alleviate the condensation phenomenon to a certain extent, but after long-term use, the flannelette will There will be a lot of dust on the surface,...

[0003] The existing method is generally to paste flannelette on the wind deflector or paste an electric heating sheet on the air outlet. The scheme of pasting flannelette on the wind deflector can alleviate the condensation phenomenon to a certain extent, but after long-term use, the flannelette will There will be a lot of dust on the surface, which will affect the overall appearance of the air conditioner

The electric heating solution can solve the condensation problem to a certain extent, but in the case of low air outlet temperature, it is necessary to increase the electric heating power, increase energy consumption and have certain safety hazards
