The temperature in device exit come judge refrigerate indoor air temperature whether be reduced to setting value, the air themperature inside refrigeration equipment
Compressor is shut down when being reduced to set temperature lower limit, until the air themperature inside refrigeration equipment rises to temperature controller setting
Compressor just turns back on work when temperature upper limit.Since there are the larger temperature difference with storing temperature for air themperature, so when compression
When machine is shut down, storing temperature is not reduced to set temperature, therefore storing heat quickly heats refrigeration equipment inner air,
Temperature is increased to compressor and turns back on work, directly results in the frequent start-stop of compressor.Cooling rate makes the section of refrigerator-freezer slowly
