Let's talk to you today Temperature sensor The type and function of.
1. Indoor temperature sensor
It is installed in the air inlet of the evaporator in the air conditioner room and supported by plastic parts. It can be used to detect whether the indoor temperature reaches the set value. Its functions are as follows.
① It is used for automatic control of indoor ambient temperature during heating or cooling.
② When heating, it is used to control the operation of auxiliary electric heater.
2. Indoor evaporator pipeline temperature sensor.
It is installed in the indoor evaporator pipeline. The outside is packed with metal tube, and she is in direct contact with the pipeline, so the measured temperature is close to the evaporation of the refrigeration system. Its functions are as follows.
① Process control during cooling in summer. (prevent insufficient refrigerant in the system or frosting of indoor evaporator)
② It is used for cold wind control during heating in winter.
③ Used to control the speed of indoor fan motor.
④ Cooperating with single chip microcomputer to realize fault self diagnosis.
⑤ It is used for defrosting of outdoor unit during heating.
3. Outdoor ambient temperature sensor.
It is installed on the radiator of outdoor unit. It is supported by plastic parts and used to detect the outdoor ambient temperature. Its main functions are as follows.
① When cooling or heating, it is used to control the speed of outdoor fan motor.
② It is used for automatic protection of control system when outdoor temperature is too low or too high.
4. Outdoor condenser pipeline temperature sensor.
It is installed on the radiator of outdoor unit and packaged with metal tube to detect the temperature of outdoor pipeline. Its main functions are as follows.
① It is used for defrosting outdoor unit during heating.
② When refrigeration or heating, it is used for overheat protection or anti freezing protection.
