Air conditioner, refrigeration control method and storage medium for air conditioner

Abstract

The invention discloses an air conditioner, a refrigeration control method and a storage medium of the air conditioner. The refrigeration control method of the air conditioner obtains the first indoor pipeline temperature of the evaporator when the air conditioner is in a low-temperature refrigeration mode, And calculate the first temperature difference between the preset anti-freezing temperature threshold and the first indoor pipeline temperature; according to the first temperature difference, control the operation of a corresponding number of fans in the fan unit. When the present invention refrigerates under low temperature conditions, based on the temperature difference between the first indoor pipeline temperature of the evaporator and the anti-freezing temperature threshold, the operation of the corresponding number of fans in the fan unit is controlled correspondingly. For example, when the cooling capacity is large, Reduce the number of fans running in the fan group. It avoids the high and low frequency switching operation of the compressor and the frequent start and stop of the fan, increases the service life of the compressor and fan of the air conditioner, reduces the working noise of the air conditioner, and improves the user experience.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner, a refrigeration control method for the air conditioner, and a computer-readable storage medium. Background technique [0002] In a low-temperature environment, the general air-conditioning system’s cooling capacity cannot reach the nominal value, nor can it meet the demand for high-capacity output at low temperatures. At present, in order to achieve the nominal value, the air conditioner controls the high-frequency operation of the compressor at low temperature or controls the frequent start and stop of the external fan, thereby increasing the pressure ratio and thus improving the cooling capacity. When the heat exchange area of ​​the internal unit is small, this solution is likely to cause the anti-freezing program to start, causing the compressor to frequently switch between high and low frequencies, which affects the service life of the com...
