A. Cooling Operation
The vapor refrigerants that compressed to high temperature & high pressure conditions in the
compressor, turn into liquid refrigerant of high temperature and high pressure passing through the
condenser, and then turn into the liquid refrigerants of low temperature and low pressure conditions by
passing through the capillary tubes. The liquid refrigerant of low temperature & low pressure absorbs
the surrounding heat while evaporating in the evaporator. Then, it is sucked in the compressor by
turning into saturated vapor.
B. Heating Operation
The electric heater inside of the hot water tank heats the supplied water. The temperature of hot
