(1) data referred to the following conditions :
internal exchanger water = 12/7°C
external exchanger water = 30/35°C
(2) The total absorbed power is obtained adding the compressors absorbed power + the power absorbed by the auxiliary
circuit.
(3) data referred to the following conditions :
WATER TO INTERNAL EXCHANGER 40/45°C
External exchanger inlet water = 10°C
The water flow in the external exchanger is the same of the cooling operation.
(4) PHE = plates
(5) water connections both source side and utility side
