CONDENSER
High temperature and high pressure gas state refrigerant discharged from the compressor is converted to a liquid state as it is cooled
down by the heat emission in the outdoor condenser unit, and sent to the evaporator.
COMPRESSOR
Low temperature and low pressure refrigerant is compressed and sent to the cycling system
EVAPORATOR
Liquid refrigerant sucked in through the capillary tubes cools down the room by absorbing the surrounding heat as it evaporates
(converting from liquid to gas). (Absorbing heat required for evaporation)
SERVICE VALVE

refrigerant injection, refrigerant purging, and indoor-outdoor unit connection.
ACCUMULATOR
Accumulator prevents the flow of liquid-state refrigerant into the compressor. (Liquid-state refrigerant flowing into the compressor
will overload the compressor.)
