Q1. Working Principle of Air Conditioning System, Refrigeration and Air Conditioning.
Ans. 
Air conditioning and refrigeration systems work on the principle of heat transfer and phase change of refrigerant.
• Air conditioning system cools and dehumidifies air in a room or building.

• Refrigeration system removes heat from a space and transfers it to the outside environment.

• Both systems use a refrigerant to absorb and release heat through phase change.

• Air conditioning system uses a compressor, evaporator, condenser,...read more

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

Q1. Working Principle of Air Conditioning System.
Ans. 
Air conditioning systems work by removing heat from indoor air and transferring it outside, cooling the air in the process.
• Air conditioning systems use refrigerant to absorb and release heat, allowing for the transfer of heat from inside to outside.

• The refrigerant circulates through a closed loop system of coils, compressors, and fans to cool and dehumidify the air.

• The cooled air is then distributed throughout the buil...read more

Q2. Describe Vapour Compression Refrigeration System.
Ans. 
Vapour Compression Refrigeration System is a common method used for cooling in various applications.
• Consists of four main components: compressor, condenser, expansion valve, and evaporator

• Refrigerant circulates through the system, changing from liquid to vapor and back to liquid

• Compressor increases the pressure and temperature of the refrigerant vapor

• Condenser removes heat from the refrigerant vapor, causing it to cond...read more
