Abstract

The invention discloses a method for controlling an electronic expansion valve of an indoor unit of an air conditioner. The method for controlling an electronic expansion valve of an indoor unit of an air conditioner includes the steps of: acquiring environmental parameters; calling a corresponding pre-stored operation rule table according to the environmental parameters; The operating parameters pre-stored in the pre-stored operation rule table are used to control the operation of the electronic expansion valve. The electronic expansion valve control method of the air conditioner indoor unit of the present invention can simplify the control mode of the electronic expansion valve.

Description

technical field [0001] The invention relates to the technical field of control methods for multi-connected air conditioner indoor units, in particular to an electronic expansion valve control method for air conditioner indoor units. Background technique [0002] The multi-connected air conditioner operates through one outdoor unit connected to multiple indoor units, and the multiple indoor units are independently adjusted and operated in multiple rooms. When the multi-split air conditioner is running, it is necessary to adjust the opening of the electronic expansion valve according to the indoor temperature changes of different rooms in real time. For example, when cooling is required, the opening of the electronic expansion valve should be increased; opening decreases. However, the conventional electronic expansion valve adjustment method needs to be controlled through complex calculations, and the opening is not easy to adjust, which can easily lead to excessive changes i...
