Air conditioner control method and device, air conditioner and computer readable storage medium

Abstract

The invention provides an air conditioner control method and device, an air conditioner and a computer readable storage medium. The method comprises the steps that a temperature of an indoor air cavity and relative humidity of the indoor air cavity of the air conditioner in an air mixing mode are obtained; a target condensation temperature corresponding to the relative humidity of the indoor air cavity is determined; and if the temperature of the indoor air cavity is smaller than the target condensation temperature, a compressor is controlled to operate at a reduced frequency and / or a fan of the air conditioner is controlled to operate at an higher speed, so that the temperature of the indoor air cavity is increased. According to the method, corresponding target condensation temperatures can be accurately determined according to the relative humidity of the different indoor air cavities, then the obtained temperature of the indoor air cavities is compared with the obtained target condensation temperature corresponding to the relative humidity, the operation frequency of the compressor and / or the rotating speed of the fan are / is accurately controlled according to the comparison result, then the temperature of the indoor air cavity is larger than the condensation temperature, so that generation of condensate water in the indoor air cavity is avoided or reduced, and meanwhile it can be guaranteed that the fresh air volume and the refrigeration effect are not affected.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner control method and device, an air conditioner, and a computer-readable storage medium. Background technique [0002] When the air conditioner is in the mixed air mode, when the high-temperature fresh air passing through the air energy heat exchanger is mixed with the low-temperature internal circulating air passing through the heat exchanger, a large amount of condensed water will be generated in the mixed air chamber, and part of the condensed water may be blown to the Outside, another part may flow out to the room or the ceiling through the gap of the air conditioner, which will cause inconvenience to the user's life.

Problems solved by technology

[0002] When the air conditioner is in the mixed air mode, when the high-temperature fresh air passing through the air energy heat exchanger is mixed with the low-temperature internal circulating air passing through the heat exchanger, a large amount of condensed water will be generated in the mixed air chamber, and part of the condensed water may be blown to the Outside, another part may flow out to the room or the ceiling through the gap of the air conditioner, which will cause inconvenience to the user's life

[0003] In order to reduce the generation of condensed water, a related technology uses sealing foam or structural fasteners to perform thermal insulation and sealing to isolate or reduce the contact between fresh air and cold air. However, this method increases material costs and processing costs, and It will lead to an increase in the assembly process and failure rate, which in turn will increase the after-sales cost and maintenance difficulty

[0004] In another related technology, the temperature of the air in the air mixing chamber is controlled by limiting the frequency of the compressor or the speed of the fan, so that the air temperature is higher than a set dew point temperature. However, this method is adopted by reducing The cooling capacity of the air conditioner is used to reduce the generation of condensed water, and this method is not based on the current humidity, which makes the entire control process prone to the problem of overshooting or insufficient control volume, and the control accuracy is low
