* Nominal Eurovent conditions:
-
evaporator entering/leaving water temperature = 12°C/7°C, condenser entering/leaving water temperature = 30°C/35°C
-
evaporator and condenser fouling factor = 0.000044 m
2
K/W
-
condensing temperature dew point 45°C
-
fluid temperature = condensing temperature at dew point - refrigerant glide - 5 K subcooling
-
Net cooling capacity = gross cooling capacity minus the capacity corresponding to the evaporator pressure drop (flow x drop/0.3)
