Method for controlling air conditioner

Abstract

The invention discloses a method for controlling an air conditioner. The method comprises the steps that when a received air-conditioner control instruction is a refrigeration energy-saving comfortable instruction and the current indoor temperature is not lower than an indoor environment temperature threshold value, the variable frequency air conditioner is controlled to run according to the original variable frequency control manner of the variable frequency air conditioner; or else, the target frequency of a compressor worked out according to the original variable frequency control manner is obtained, and whether the target frequency of the compressor is smaller than the first set frequency of the compressor or not is judged; if yes, the compressor is controlled to run at the first set frequency of the compressor, and an outdoor fan is controlled to run at the set rotating speed; and if not, the compressor and the outdoor fan are controlled to run according to the original variable frequency control manner. In the original variable frequency control manner, room temperature PID control or fuzzy control is performed on the compressor. By the application of the method for controlling the air conditioner, the energy-saving performance 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 reduce the power consumption of the inverter air conditioner, there is a control method for the inverter air conditioner in the prior art. By detecting the outdoor ambient temperature, a preset compressor operating frequency corresponding to the outdoor ambient temperature is selected from several preset operating frequencies of the compressors. Control the inverter air conditioner with the preset compressor operating frequency. The lower the outdoor ambient temperature, the lower the corresponding preset compressor f...

Problems solved by technology

However, cold air will enter the human body from the respiratory tract, and after a long time of blowing, there will still be cold symptoms such as dry mouth and nose, sore throat, etc., which cannot fundamentally solve the problem of uncomfortable cooling
