What is the function of the air conditioning temperature sensor?
The air conditioner temperature sensor is the commander of the air conditioner's work instructions. It can monitor the temperature changes of the internal components of the air conditioner. When the air conditioner reaches the user set temperature, it will control the compressor to stop running. There are multiple temperature sensors inside the air conditioner, of which the most basic three are the indoor temperature sensor, the outdoor temperature sensor, and the compressor temperature sensor. Depending on the location, the function of the air conditioner temperature sensor is different.
Indoor temperature sensor
Its location is at the air outlet of the indoor switch. Its main function is to measure the indoor ambient temperature during the heating or cooling process of the air conditioner, keep the compressor running for a reasonable time, and control the compression when the cooling or heating temperature is reached. When the air conditioner is turned on in the automatic mode, monitor the working condition of the compressor; monitor the operating speed of the indoor fan of the air conditioner.
Indoor coil temperature sensor
Its location is in the housing of the indoor heat exchanger. Its main function is to avoid excessive cooling or heating of the machine during the cooling or heating process of the air conditioner; real-time monitoring of the operating speed of the indoor fan; outdoor heating during the heating process in a cold environment Defrost to ensure normal operation of the air conditioner.
Outdoor temperature sensor
Its location is on the outdoor switch. Its main function is to monitor the outdoor ambient temperature during the heating or cooling process of the air conditioner, and at the same time, to control the operating speed of the outdoor fan.
outdoor coil temperature sensor
It is located in the outer shell of the heat exchanger. Its main function is to ensure that the outdoor exchanger will not overheat during the heating process of the air conditioner. At the same time, it will not be too cold and freeze during the cooling process of the air conditioner. During defrosting operation, monitor the switch temperature within a reasonable range.
Compressor temperature sensor
Its location is on the compressor volleyball pipe. Its main function is to monitor the temperature of the exhaust pipe to determine the opening degree of the expansion valve, thereby controlling the compressor operating rate and ensuring that the temperature of the exhaust pipe will not be too high.
The temperature sensor settings of each air conditioner are different, so the actual cooling and heating effects of the air conditioner are also different. Brand air conditioners usually set 25 degrees as the horizontal line, and the air conditioner temperature sensor works in the positive and negative range of 25 degrees. As the temperature becomes higher, its resistance decreases, and as the temperature becomes lower, it increases.
It can be seen that the air conditioner temperature sensor is an important work center of the air conditioner. It is the observation of the automatic control system of the air conditioner and transmits the machine information to the controller. Because of its high working frequency, many air conditioner failure problems are caused by the air conditioner temperature sensor of. The maintenance personnel can identify and repair the air conditioner temperature sensor through the machine, which can improve the maintenance efficiency.
