Background

At present, a compressor is a core component of a household air conditioner. It is a driven fluid machine for lifting low-pressure gas into high-pressure gas, and is a heart of refrigerating system. The refrigerating cycle is powered by sucking low-temperature and low-pressure refrigerant gas from the air suction pipe, driving the piston to compress the refrigerant gas through the operation of the motor, and discharging high-temperature and high-pressure refrigerant gas to the exhaust pipe. The compressor has three terminals, which are respectively labeled with C, S, R three letters, wherein C is a common end of a winding and is usually connected with a live wire for supplying power to the compressor, S is a tap of a starting winding and is generally connected with one end of a capacitor of the compressor independently, R represents a tap of an operating winding and is generally connected with one end of the capacitor together with a zero line for supplying power. If the compressor is wired incorrectly, the compressor is easily damaged, and other electrical components can be damaged. Therefore, in the process of wiring the compressor, the correctness of each wiring needs to be carefully and carefully confirmed by referring to specifications, and the method is a great test for people with less experience.
