Match the parts of an electronically controlled expansion valve to their functions.
1. Remotely controlled valve
2. Thermistor
3. Transformer
* Placed in the refrigerant stream near the evaporator outlet to respond quickly to temperature changes
* Transmits a voltage change to an electronic controller
* Adjusts opening in metering devices
Answer (2)
The matched functions of electronically controlled expansion valves include the remotely controlled valve adjusting the opening in metering devices, the thermistor responding to temperature changes, and the transformer transmitting voltage changes to the electronic controller. These elements work together to optimize refrigerant flow in HVAC systems. Understanding these functions helps in designing efficient thermal management systems. ;
