Thermocouple

Thermocouple is a device used to measure temperature. In a heat pump, it is used to measure the temperature of the refrigerant as it flows through the system. This information is used by the control system of the heat pump to regulate the operation of the compressor and other components of the system to ensure that the refrigerant is at the proper temperature for efficient heat transfer.

The HVAC thermocouple can also be used to detect problems in the system, such as a refrigerant leak or a malfunctioning compressor. 

A heat pump thermocouple includes a hot wire made of a high-conductivity material and a cold wire made of a low-conductivity material, which were joined at one end to form a junction where the temperature could be measured. For example, the thermocouple may be used to turn the heat pump on and off, or to adjust the flow of refrigerant through the system. It may also be used to monitor the temperature of the heat pump's compressor, which is an important component that helps to transfer heat from one location to another.
