The method of judging the quality of the PTC starter: PTC starter can be measured by the resistance file R ×1 ohm of the multimeter, and the M and S holes should have a resistance of more than ten to twenty ohms, if the resistance value is found to be too large or infinite, it means that it has failed.
Compressor: A driven fluid machine that lifts low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. It inhales low temperature and low pressure refrigerant gas from the suction pipe, drives the piston to compress it through the motor operation, and discharges high temperature and high pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle, so as to realize the refrigeration cycle of compression →condensation (exothermic) → expansion → evaporation (endothermic).
PTC. Initiator has the following characteristics
The resistance value at normal room temperature is very small, and when a certain temperature value is reached, the resistance value will increase sharply thousands of times, this temperature is called the critical temperature also known as the Curie point or critical point). The critical point can be adapted to meet different temperature requirements by adjusting the raw material formulation according to different uses. The critical temperature of PTC components used in refrigerator compressors is generally 50 °C ~ 60 °C.
