Electronic Expansion Valve - How it works ETS 5M HVAC

The video tutorial explains the components and operation of a refrigeration system, including the compressor, condenser, expansion valve, and evaporator. It details the refrigerant cycle, heat exchange process, and the role of each component. The tutorial also covers different types of expansion valves, focusing on the electronic expansion valve, its mechanism, and how it provides precise control of refrigerant flow using a stepper motor and sensors.

What are the consequences of having too much or too little refrigerant in the evaporator?

How does the stepper motor function in the electronic expansion valve?

Explain how the temperature sensor and pressure transducer work together in the system.

What is the significance of the superheat in a refrigeration system?
