Q2. Describe Vapour Compression Refrigeration System.
Ans. 
Vapour Compression Refrigeration System is a common refrigeration system used in air conditioning and refrigeration applications.
• It works by compressing refrigerant vapor to increase its temperature and pressure.

• The high-pressure vapor then condenses into a liquid, releasing heat.

• The liquid refrigerant then passes through an expansion valve, where it evaporates and cools the surrounding area.

• The low-pressure vapor is t...read more
