Abstract

The invention discloses a control method of an air conditioner. The control method comprises the following steps: S1, starting the air conditioner and enabling the air conditioner to be in refrigeration operation; S2, detecting the outdoor environmental temperature T1; S3, when T1 is within a set value range, enabling the air conditioner to be in a low-temperature refrigeration mode; S4, regulating the operating frequency of a compressor according to a sub-region to which the T1 belongs, and exiting from the low-temperature refrigeration mode when detecting an exit condition. According to the control method of the air conditioner disclosed by the embodiment of the invention, the technical problems of indoor unit freezing, compressor liquid return and the like under a low-temperature environment are solved.

Description

Technical field [0001] The invention relates to the technical field of automatic control, and in particular to a control method of an air conditioner. Background technique [0002] In the inverter air conditioner control system in the related technology, the operation mode of the air conditioner is based on the set temperature and the current indoor ambient temperature as the data basis to adjust the compressor frequency. If the indoor ambient temperature is very different from the set temperature, the compressor will run at high frequency. If the indoor ambient temperature is very different from the set temperature, the compressor will run at low frequency. [0003] When the outdoor environment temperature is low, if there is still cooling demand in the room at this time, the air conditioner will be in a higher frequency state when operating according to the existing control mode, which is more likely to cause the indoor unit to freeze and the compressor to return. Liquid and oth...
