- Q1. Define one cycle of refrigeration with thermodynamic processes?
- Ans.
Refrigeration cycle involves four thermodynamic processes: compression, condensation, expansion, and evaporation.
The refrigerant is compressed by a compressor, increasing its temperature and pressure.
The high-pressure refrigerant then flows through a condenser, where it releases heat and condenses into a liquid.
The liquid refrigerant then passes through an expansion valve, where it undergoes a pressure drop and becomes...
- Q2. Explain the functions of parts of the Air Conditioner.
- Ans.
The functions of parts of an Air Conditioner include cooling, dehumidifying, filtering, and circulating air.
Compressor: compresses and circulates refrigerant to cool the air
Condenser: releases heat from the refrigerant to the outside air
Evaporator: absorbs heat from the air and cools it down
Expansion valve: regulates the flow of refrigerant into the evaporator
Fan: circulates the air over the evaporator and condenser co...

Air conditioning system uses a compressor, evaporator, condenser,...
- 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...
