Vapour compression refrigeration, T-s diagram

Question

Accepted Answer

Vapour compression refrigeration is a process used to cool a space or substance by removing heat through the use of a refrigerant.

Vapour compression refrigeration uses a compressor, condenser, expansion valve, and evaporator to remove heat from a space or substance.
The refrigerant is compressed, which increases its temperature and pressure, and then condensed, which releases heat.
The refrigerant then passes through an expansion valve, which reduces its pressure and temperature, causing it to evaporate and absorb heat from the space or substance being cooled.
The refrigerant then returns to the compressor to repeat the cycle.
Examples of vapour compression refrigeration systems include air conditioning units, refrigerators, and heat pumps.
