Vapor compression refrigeration

Vapor compression refrigeration

Vapor compression refrigeration is a widely used cooling technology that uses the principle of thermodynamics to provide cooling. It works by circulating a refrigerant in a closed loop through a series of components, which include a compressor, condenser, expansion valve, and evaporator.

The compressor is the heart of the system and is responsible for compressing the refrigerant gas and raising its temperature. This hot, high-pressure gas then flows through the condenser, which is a heat exchanger that cools the gas and condenses it into a liquid.

The high-pressure liquid refrigerant then flows through the expansion valve, which reduces the pressure of the refrigerant and allows it to expand rapidly. This expansion causes the refrigerant to evaporate and absorb heat from the surrounding environment, cooling the area around the evaporator.

The low-pressure, low-temperature gas refrigerant then flows back to the compressor, and the process repeats itself.

Vapor compression refrigeration is widely used in refrigeration and air conditioning systems for residential, commercial, and industrial applications. It is efficient, cost-effective, and provides consistent cooling performance.

Example : Chiller, Split AC, Package AC, Tower AC, Ductable Split AC

 FAQ

Ques 1 - What are the 4 stages of vapor-compression refrigeration cycle?

Ans- It involves four main stages, which are as follows:

        Compression

        Condensation

        Expansion

        Evaporation

Ques 2 - What is the use of vapour compression?

Ans - Vapor compression cooling systems can be used for refrigeration and dehumidification.

Ques 3 - What is the temperature of chiller?

Ans. – Generally in HVAC Application, chillers receive water at 12°C (entering temperature), and cool it to 7°C (leaving temperature).
