Refrigeration cycle is a process in which refrigerant absorbs heat from the indoor air and releases it outside to cool the indoor space.

• Refrigerant absorbs heat from indoor air in the evaporator coil

• The refrigerant is then compressed in the compressor to increase its temperature and pressure

• The hot refrigerant releases heat to the outside air in the condenser coil

• The refrigerant expands in the expansion valve, lowering its temperature and pressure, and the cycle repeats
