Abstract

The invention discloses a method for controlling the constant air volume of an indoor unit of an air conditioner, comprising: obtaining the real-time power of a motor; value, the new power value excludes the inverter power and motor loss, and retains the power used to do work; at the motor speed corresponding to the corrected power value of the motor, calculate the difference between the corrected power value of the motor and the preset power standard value The power difference and the target speed required by the motor to reach the predetermined constant air volume and control the motor to run at the target speed. The invention also discloses a constant air volume control device of the indoor unit of the air conditioner and the indoor unit of the air conditioner. The present invention can calculate the speed needed to realize the constant air volume according to the influence of the wind resistance on the power, and the model formula to realize the constant air volume control of the indoor unit of the air conditioner. Heating effect.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a constant air volume control method and device for an air conditioner indoor unit and an air conditioner indoor unit with the device. Background technique [0002] Generally, when using an air conditioner for cooling or heating, what is most needed is the constant control of the air volume of the indoor unit. If the air volume is too small or not constant, it will cause the cooling and heating to fail, which will lead to the cooling and heating of the air conditioner. The thermal effect is poor. At present, the indoor units of air conditioners all use constant speed to control the air volume. Although in theory, the constant speed corresponds to the constant air volume, but in fact, the air conditioner will be affected by various factors during the use of the air conditioner. not constant. [0003] There are many factors that affect the air volume of the indoor unit, including:...
