Temperature sensor refers to a sensor that can feel the temperature and convert it into an available output signal.The temperature sensor is the core part of the temperature measuring instrument, with a wide variety of varieties.The air conditioner temperature sensor is a temperature sensor for air conditioners.
Air conditioner temperature sensor location
The air conditioner is composed of indoor hanging or cabinet and outdoor console.Indoor machine back to the air.
The role of air conditioner temperature sensor
The location of indoor temperature sensor is at the air outlet of indoor switches. Its main function is to measure the indoor environment temperature during the process of air conditioning heating or refrigeration, maintain a reasonable time for the operation of the compressor, and when the refrigeration or heating temperature is reached or heating temperatureControl the compressor stop; during the automatic mode of the air conditioner, monitor the work of the compressor; monitor the operating speed of the air -conditioning indoor fan.The temperature sensing of the indoor ducts is located in the shell of the indoor heat switch. Its main function is to avoid the cooling or heating of the machine during the cooling or heating process of the air conditioner; the operating rate of the indoor fan in real time;During the heat, outdoor frosting to ensure the normal operation of the air conditioner.The outdoor temperature sensor is located on the outdoor switch. Its main function is to monitor the outdoor ambient temperature during the heating or refrigeration process of air conditioning. At the same time, control the operating rate of outdoor fan.The location of the outdoor duct temperature sensor is located in the outdoor hot switch shell. Its main function is to ensure that the air conditioner will not be overheated during the heating process. At the same time, during the cooling process of the air conditioner, it will not freeze and freeze.When the weather, when the air conditioner is frost, the temperature of the switch is in a reasonable range.The position of the compressor temperature sensor is on the volleyball pipe of the compressor. Its main function is to monitor the temperature of the exhaust pipe, so as to determine the expansion valve opening level, thereby controlling the operating ratehigh.
Air conditioner temperature sensor resistance value
Common air -conditioning brand temperature sensor resistance values. Generally, manufacturers determine how large the resistance of the temperature sensor is based on the parameters of the micro -computer control motherboard of the air conditioner indoor machine, such as Haier, room temperature of 23K, tube temperature 10K, and 50K when the exhaust pipe temperature is 80 degrees at 80 degrees.The normal temperature is 400 ~ 600K. When the resistance value increases with the temperature, the temperature decreases, and the room temperature sensor of the LG3681HT is 5K, the tube temperature sensor is 10K, Gree 7053s room temperature sensor is 5K, the tube temperature sensor is 10K to 10KThe outdoor tube temperature sensor is 10k, the sensors of Kelong 35N2F are 20K, the sensors of the new air conditioner are 10K, and the sensors of Changhong now have 10K.
Air conditioning temperature sensor principle
According to temperature changes, the resistance of the sensor also changes. Although the computer board does not know the temperature, it knows the resistance value.
How much is the air conditioner temperature sensor
The air conditioner temperature sensor is now around 188.
