Heating and Cooling VRF system

The video tutorial explains the operation of a reversing valve in HVAC systems, detailing how it functions in both heating and cooling modes. It describes the flow of refrigerant through various components, such as expansion and check valves, and highlights the properties of refrigerants like R410A. The tutorial also covers how the compressor increases the temperature and pressure of the refrigerant to make thermal energy usable. The video concludes with a summary of the key points discussed.

What happens to the refrigerant when it cools down after absorbing heat?

How does the compressor affect the temperature and pressure of the refrigerant?
