Method for controlling variable frequency air conditioner

Abstract

The invention discloses a method for controlling a variable frequency air conditioner . The method comprises the following steps: an air conditioner is turned on to operate under a refrigeration mode; after the operation time of a compressor of the air conditioner reaches set operation time, the present indoor temperature detected by an indoor temperature sensor is obtained as the first indoor temperature; the difference value between the first indoor temperature and set compensation temperature serves as the second indoor temperature; the temperature difference between the second indoor temperature and the present indoor target temperature is calculated to obtain the indoor temperature difference; the room temperature PID operation is performed according to the indoor temperature difference to obtain the first target frequency; the second indoor temperature is compared with set comfortable temperature; and the room temperature PID control or the dual PID control is performed according to the comparison result. The indoor temperature adjusting comfort of the air conditioner and the low-power-consumption energy conservation of the air conditioner are taken into consideration, and the problem of uncomfortable refrigeration due to blowing out of cold wind by a traditional variable frequency air conditioner is solved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a method for controlling an inverter air conditioner. Background technique [0002] In the hot summer, many people cannot do without the air conditioner all day and all night. However, blowing air conditioners for a long time has many harms to the human body, and it is easy to get air conditioner diseases. [0003] Although the existing inverter air conditioner can control the operating frequency of the compressor, its control basis is only the indoor temperature and the set indoor target temperature, and will not change the air outlet temperature of the air conditioner. And in order to reach fast refrigeration, the outlet air temperature of existing air conditioner will be far lower than setting temperature, and the air outlet air temperature of air conditioner is low, and the wind that blows out is cold wind. When the cold wind blows on the human body, it...
