Within the household air conditioning machine evaporator tube temperature sensors have what effect?
Against the cold wind protection and overload protection function. The cold wind protection mechanism: The overload protection mechanism:
Self heating type: protection against the cold wind in the condition of air conditioning heating, in order to prevent the indoor machine out of the cold wind blowing, after startup CPU begin to detect the temperature of the evaporator, when temperature is lower than 22 degrees Celsius, indoor fan motor doesn't work; When the temperature is greater than or equal to 22 degrees Celsius, indoor fan blow down a peg or two, when the tube temperature is greater than or equal to 40 degrees Celsius or compressor running after 2 min, indoor fan according to the set speed running. Heating run against the overload protection: when the CPU continuously 4 s detected tube evaporator temperature greater than or equal to 56 degrees Celsius, outdoor fan stop, when they tested the tube temperature less than or equal to 52 degrees Celsius, the indoor fan.
Hello! Within the machine environment temperature sensor: the main testing the temperature inside the room, the start-stop control air conditioning. Within the machine coil sensor: the main testing machine in the tube temperature and winter frost to prevent the cold wind, to the machine. (there are plenty of machine tube warms the frost) In the summer, writers in freeze protection!
