Inverter air conditioner and NTC temperature sensor

The biggest difference between an inverter air conditioner and a fixed frequency air conditioner is the compressor. The fixed speed compressor is replaced by an inverter compressor, and an inverter control system is added, which has a built-in NTC temperature sensor. Its function is to detect the air in the air-conditioned room and control and adjust the air conditioner to work normally. In order to automatically adjust the temperature in the room, a temperature sensor must be installed in the air-conditioning system. The temperature can be precisely controlled.
The frequency conversion air conditioner is based on the difference between the set working temperature and the indoor temperature for frequency conversion speed regulation. The larger the difference, the higher the compressor working frequency. The indoor coil NTC temperature sensor plays the role of protection detection, refrigeration lack of fluorine detection, heating protection against cold wind blowing, and overheating protection detection in indoor coil cooling and subcooling. If the indoor coil temperature drops below +3℃ to prevent frosting and stop (subcooling) for heating, the outdoor coil NTC temperature sensor can detect the heating and defrosting temperature and the cooling and condensing temperature. Frequency conversion refrigeration reduces the frequency to prevent the coil from heating up.

The outer ring temperature NTC temperature sensor is used to control the speed of the outdoor fan and preheat the compressor in winter. The exhaust NTC temperature sensor reduces the frequency of the inverter compressor to avoid overheating of the external machine and detection of fluorine deficiency. The suction NTC temperature sensor has the function of controlling the flow of refrigerant, and has the function of stepping motor to control the throttle valve.
