HOT GAS TEMPERATURE °C This value specifies the temperature of the gaseous refrigerant at the condenser inlet.
HIGH PRESSURE bar
LOW PRESSURE bar
EVAPORATOR TEMP. °C In the evaporator, the refrigerant is evaporated at low pressure. As this happens, heat is extracted from
the air flow.
CONDENSER TEMP. °C In the condenser, the refrigerant is liquefied at high pressure. This releases heat which is transferred to
the heating medium.
