Q1. What is refrigeration cycle? Commissioning stages of Data center?
Ans. 
The refrigeration cycle is a process that removes heat from a space and transfers it to the external environment.
• The refrigeration cycle consists of four main components: compressor, condenser, expansion valve, and evaporator.

• The compressor compresses the refrigerant gas, raising its temperature and pressure.

• The high-pressure refrigerant then flows to the condenser, where it releases heat to the surroundings and conden...read more
