The thermowells are usually used in conjunction with various types of temperature sensing elements, such as thermocouples, RTDs, etc. The principle of operation is based on the good thermal conductivity of copper. The working principle is based on the good thermal conductivity of copper, when the ambient temperature changes, the heat will be quickly passed through the copper casing to the internal temperature sensing element. The temperature sensing element will change its own physical properties according to the temperature change, for example, thermocouple will produce thermal potential, resistance value of RTD will change. These changes in physical characteristics will be converted into corresponding electrical signals, through the connection of the measuring instrument or control system, you can accurately measure the value of the ambient temperature.

• 1. Refrigerators and freezers

  Domestic refrigerators: The thermowell is usually installed in the freezer and refrigerator compartments of a refrigerator to monitor the temperature inside the box. In the freezer compartment, it ensures that the temperature is maintained in the right range, e.g. 2 - 8℃. When more food is put in or the temperature rises due to frequent opening of the door, the thermowell will signal the temperature change to the temperature control system of the refrigerator, which will activate the compressor accordingly to carry out refrigeration until the temperature returns to the set range. In the freezer compartment, the temperature sensing sleeve can ensure that the temperature is maintained at about -18℃, preventing the food from thawing and deteriorating.

• 2. Air conditioning system
  Wall-mounted air conditioners: The temperature-sensing casing is mainly used to accurately sense the indoor temperature in wall-mounted air conditioners. It is usually installed near the evaporator of the indoor unit to monitor the evaporator surface temperature or indoor return air temperature in real time. When the indoor temperature reaches the set temperature, for example, the user set to 26 ℃, the temperature sensing sleeve will be the temperature signal feedback to the air conditioning control system, the control system according to this signal to decide whether to stop the compressor or adjust the compressor operating frequency. In this way, the indoor temperature can be precisely controlled to avoid the indoor temperature being too low or too high, providing a comfortable indoor environment.
