In the sweltering summer, everyone is naturally feeling the heat, running all sorts of cooling appliances—electric fans, blowers, and some even waving hand fans. And then there’s one appliance that’s easy to turn on and delivers a wonderfully cool breeze. Air conditioners can bring coolness in the sweltering summer and warmth in the chilly winter. But which components inside an air conditioner are responsible for sensing temperature? Below, we’ll introduce the temperature-sensing components found in air conditioners. - Temperature sensor used in household air conditioners
The weather in Guangdong is hot. When the indoor temperature fails to reach the user‑set target, the compressor starts up; once the indoor temperature reaches the set point, the compressor shuts off. Air conditioner indoor units typically have 2. A certain model of temperature sensor—one type uses… Temperature sensor with epoxy encapsulation head , and there is another type—a temperature sensor with a metal sheath that is pot‑sealed at the sensing tip. These two models have distinct applications, Temperature sensor with epoxy encapsulation head The primary function of the indoor unit of an air conditioner is to sense the room temperature and adjust its operation accordingly.
If one of the sensors becomes damaged during use, we will be unable to determine its resistance; in this case, you can compare it to the resistance value of the other sensor. Under normal ambient conditions, the resistance values of these two sensors are as follows: 10K Around Ω; if the resistance is higher or lower than this value, it indicates that the sensor may be damaged. In such cases, simply replacing the sensor will suffice. Temperature sensor with a metal-sheathed encapsulated head Its primary function is to monitor the evaporator of the indoor unit. When the air conditioner malfunctions, or when the evaporator experiences excessively high or low temperatures during cooling, it triggers a protective shutdown. In cooling mode, if the evaporator temperature drops too low or frost forms on its surface, the system will also enter a protective state. The temperature sensor embedded in the metal‑encapsulated terminal serves as a key criterion for determining whether defrosting should be initiated during cooling. Under normal operating conditions, the resistance values of the two sensors on the same unit should be identical.
That concludes the introduction to the temperature sensors used in household air conditioners.
