Low-temperature refrigeration control method and device, storage medium and air conditioner

Abstract

The invention provides a low-temperature refrigeration control method and device, a storage medium and an air conditioner, and the low-temperature refrigeration control method comprises the following steps that S1, when the air conditioner is in a refrigeration mode, the outdoor environment temperature T < outer ring >, the indoor environment temperature T < inner ring > and the set temperature T < set > are obtained; S2, if it is detected that T <outer ring> is smaller than or equal to A and T -T < set > is larger than or equal to B, S3 is executed, otherwise, operation is conducted according to a conventional refrigeration mode, and A and B are preset empirical parameters; and S3, the system enters into a low-temperature refrigeration powerful mode to operate, and the high-frequency upper limit of a compressor is recovered. According to the low-temperature refrigeration control method, the low-temperature refrigeration effect is guaranteed, meanwhile, the dehumidification capacity is high, condensation is prevented, and the use experience of a user is greatly improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a low-temperature refrigeration control method, device, storage medium and air conditioner. Background technique [0002] An air conditioner, namely an air conditioner, is a common household appliance, which usually has the functions of heating and cooling. [0003] At present, when the temperature of conventional air conditioners is lower than 30°C, the upper limit frequency generally decreases significantly (90Hz→60Hz), and the performance is greatly attenuated. However, in fact, many indoor activities such as restaurants and KTVs have poor cooling effects when the outdoor ambient temperature is low. The existing low-temperature cooling function is more about compensating the set temperature to keep the air conditioner cooling. More performance degradation. [0004] Due to insufficient cooling capacity to meet the demand, the user feels poor. Contents of the invent...
