Title:
METHOD FOR CONTROLLING AIR-CONDITIONER AIR COOLING UNIT AND AIR-CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2018/223758
Kind Code:
A1
Abstract:
Disclosed are a method for controlling an air-conditioner air cooling unit and an air-conditioner. The air-cooling unit comprises a fan and a compressor connected to the fan. The control method comprises the following steps: when the air-cooling unit is operating, detecting an air intake pressure and expelled air pressure of the compressor (S1); calculating a pressure difference between the expelled air pressure and the air intake pressure of the compressor; and according to the expelled air pressure and the pressure difference, regulating the rotational speed of the fan in real time (S2). Regulating the rotational speed of the fan by determining changes in pressure difference can prevent return oil of the unit being poor when the pressure difference is too small, and consumption being too high and unit failure when the pressure difference is too large, meaning that the compressor is working optimally throughout, improving stability and reliability of unit operation.
