Q1. Explain Refrigeration cycle
Ans. 
Refrigeration cycle is a process in which a refrigerant absorbs heat from a low-temperature space and releases it in a high-temperature space.
• Refrigerant absorbs heat from the low-temperature space (evaporator)

• Refrigerant is compressed to increase its temperature and pressure

• High-temperature refrigerant releases heat in the condenser

• Refrigerant expands in the expansion valve to lower its temperature and pressure
