Question

Correct sequence of vaper compression refrigerator

Answer 1

Answer:

The vapour refrigerator cycle involves four components as a sequence are compressor, condenser, expansion and evaporater.

Answer 2

Answer:

The Correct sequence of Vapour Compression Refrigerator is

Compressor- Condenser- expansion valve – evaporator.

Explanation:

• It starts with the compressor when electricity is supplied to the compressor, it compresses the refrigerant to higher pressure and higher temperature.
• Then that high-pressure high-temperature refrigerant in the vapor phase is condensed into the liquid phase at constant pressure. Then this liquid refrigerant is throttled in the throttling valve and it reduces the temperature and pressure of the refrigerant.
• This low-pressure low temperature liquid refrigerant is passed through the evaporator where it absorbs heat from the surroundings and refrigerant changes phase to vapor. The surroundings get cooled.

So the sequence is,

• 1–2: Isentropic compression of vapor refrigerant to high-pressure high-temperature vapor.

• 2–3: Isobaric heat rejection to the surroundings to condense the refrigerant.
• 3–4: Isenthalpic expansion at throttling valve to reduce pressure and temperature of the refrigerant.
• 4–1: Isobaric heat absorption from the surroundings in the evaporator and liquid to vapor phase change of refrigerant.
