■ CONDENSER
High temperature and high pressure gas state coolant discharged from the compressor is converted to a liquid state as it is cooled
down by the heat emissi
on in the outdoor condenser unit, and sen t to the evaporator.
■ COMPRESSOR
Low temperature and low pressure coolant is compressed and sent to the cycling system
■ EVAPORATOR
Liqui
d coolant 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
You can open the valve by turning the need valve counterclockwise using hex wrench, and it is used for vac
uum, gas purging, coolant
injection, coolant purging, and indoor-outdoor unit connection.
■ ACCUMULATOR
Accumulator prevents the flow of liquid-state coolant into the
compressor. (Liquid-state coolant flowing int o the compressor will
overload the compressor.)
