Explain the vapour compression refrigeration cycle?

Question

Accepted Answer

The vapour compression refrigeration cycle is a thermodynamic process used in refrigeration systems to remove heat from a low-temperature space and transfer it to a high-temperature space.

The cycle consists of four main components: compressor, condenser, expansion valve, and evaporator.
The refrigerant enters the compressor as a low-pressure vapor and is compressed to a high-pressure vapor.
The high-pressure vapor then enters the condenser where it releases heat and condenses into a high-pressure liquid.
The liquid refrigerant passes through the expansion valve, which reduces its pressure and temperature.
The low-pressure liquid refrigerant then enters the evaporator where it absorbs heat from the low-temperature space and evaporates into a low-pressure vapor.
The vapor is then returned to the compressor to start the cycle again.
Example: A household refrigerator uses the vapour compression refrigeration cycle to keep the inside cool by removing heat from the food and expelling it outside.

Accepted Answer

the refrigerant changes state, heat is absorbed and expelled by the system, lowering the temperature of the conditioned space.
