What does high temperature protection at the top of compressor mean?
The overheating protection of air conditioning compressor is because the air compressor pump in the working conditions will encounter many inevitable adverse state imposed protection measures.Overheating protection of air conditioning compressor has the following possibilities:1, the external fan speed is too low, mostly by the external fan start, capacitor capacity decline caused;2, the machine condenser is too dirty, generally appear in the double temperature machine "single temperature machine or not commonly used heating for air conditioning and heating in the winter, the frost, frost can play the function of automatic cleaning, after cleaning can be excluded);3, the system is seriously lack of refrigerant, resulting in the compressor coil can not be cooled, add refrigerant can;4, installation location, environmental temperature is too high;5, compressor performance is poor (including compressor, oil shortage and other mechanical faults);6, system congestion;7 、 the power voltage is too low.
The top of the compressor is equipped with a temperature sensor. When the temperature is too high (over 110 degrees), the compressor will be stopped by the feedback of the resistance change of the sensor to the circuit board.
The main protection of the compressor, the compressor in high temperature or large current power supply is disconnected from the compressor.
