Air conditioner and its anti-condensation method

Abstract

The invention discloses an air conditioner and an anti-condensation method thereof; the anti-condensation method of the air conditioner comprises the following steps that when the air conditioner enters a refrigeration mode, a first temperature value is tested, worked out and output to a control module; when the first temperature value is less than the lower limit of a first preset temperature range, the refrigerant flow which enters an evaporator is reduced; when the first temperature value is more than the upper limit of the first preset temperature range, the refrigerant flow which enters the evaporator is increased; when the first temperature value is more than the lower limit of the first preset temperature range and less than the upper limit of the first preset temperature range, a second temperature value is tested and compared with a second preset value. According to the air conditioner and the anti-condensation method thereof, the refrigerant flow output by a throttling device is adjusted by testing the temperature of all monitoring points, so as to prevent the secondary condensation of air in the air duct of the indoor unit of the air conditioner and meanwhile prevent the frosting and icing of the evaporator, improve the refrigeration efficiency and meet the refrigeration requirements.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner and an anti-condensation method for the air conditioner. Background technique [0002] When the air conditioner enters the cooling mode, the indoor evaporator evaporates and absorbs heat, the outdoor condenser condenses and releases heat, and the indoor heat is transferred to the outdoor through the compressor to reduce the indoor ambient temperature. However, in the long-term operation in the cooling mode, the indoor unit will condense due to poor sealing of the air conditioner indoor unit, high indoor humidity, or high ambient temperature. Condensation forms water droplets that drip into the room, thereby causing damage to the indoor environment and affecting the quality of life of consumers. In the prior art, the generation of condensation is usually prevented by adding thermal insulation materials or controlling the air flow in and out of the indoor unit of...

AI Technical Summary

Problems solved by technology

However, during long-term operation in the cooling mode, the indoor unit will condense due to poor sealing of the air conditioner indoor unit, high indoor humidity, or high ambient temperature. Condensation forms water droplets that drip into the room, causing damage to the indoor environment and affecting the quality of life of consumers

In the prior art, the generation of condensation is usually prevented by adding thermal insulation materials or controlling the air flow in and out of the indoor unit of the air conditioner. The phenomenon did not play an inhibitory role; there is also a method of controlling the frequency of the compressor to prevent condensation, but this method reduces the frequency of the compressor, thereby greatly reducing the cooling capacity of the air conditioner
