The electrical system of the freezer

Refrigerators use electricity as the main energy source, rely on electric motors to drive compressors or refrigeration diodes, and are generally equipped with relay protectors and thermostats.

Refrigerator motors using compressors are classified into resistance split-phase starting type, capacitor starting type and capacitor starting capacitor operation type according to different starting methods. The motor of the hermetic compressor is installed inside the refrigeration system. It is in contact with refrigerant and refrigerating oil for a long time, and bears pressure and high temperature. Therefore, it must be resistant to refrigerant and refrigerating oil, stable electrical performance, high temperature resistance, vibration and shock resistance , There are requirements for large starting torque and keeping clean and moisture-free.
