Abstract

The invention discloses an air conditioner control method. The method includes: when a received air conditioner control instruction is an energy-saving comfortable refrigeration instruction and a current indoor temperature is not lower than a set indoor environment temperature threshold, controlling a variable-frequency air conditioner to operate according to an original variable-frequency control mode of the variable-frequency air conditioner; otherwise, acquiring a compressor target frequency calculated according to an original variable-frequency control mode, and judging whether the compressor target frequency is smaller than a first set compressor frequency or not; if yes, controlling the compressor to operate by the first set compressor frequency, and controlling an outdoor fan to operate by a set rotating speed; if not, controlling the compressor and the outdoor fan to operate according to the original variable-frequency control mode; in the original variable-frequency control mode, executing room temperature PID control or dual PID control including coil temperature PID control on the compressor, wherein a coil target temperature adopted in coil temperature PID control is determined according to real-time indoor humidity. By application of the air conditioner control method, energy saving and refrigeration comfort of the air conditioner are improved.

Description

technical field

[0001] The invention belongs to the technical field of air conditioning, and in particular relates to a method for controlling an air conditioner. Background technique

[0002] In the hot summer, the indoor air can be cooled by using the inverter air conditioner to create a cool environment for users. However, inverter air conditioners consume a lot of power and often become the main power-consuming appliances in the home.

[0003] In order to solve the uncomfortable problem caused by cold air blown out by refrigeration, the control method of controlling the operating frequency of the compressor can be based on the coil temperature of the indoor heat exchanger as the control target. In the existing coil temperature control process, the target temperature of the coil adopts a fixed value, which is generally a fixed temperature value solidified in the storage of the air conditioner. In the actual use process, there is often a phenomenon: in the case of keepin...
