(1) data referred to the following conditions :
internal exchanger water = 23/18°C
external exchanger air intake 35°C
(2) Total input is obtained from compressor input
+ fan input
(3) EER calculated as the relationship between
cooling capacity and total absorbed power.
(4) data referred to the following conditions :
water to internal exchanger 30/35°C
External air temperature : 7°C D.B./6.0°C W.B.
(5) COP calculated as the relationship between
heating capacity and total absorbed power.
(6) The indicated COPvalues were calculated
in compliance with the provisions of standard
EN 14511:2004.
(7) SCROLL = scroll compressor
(8) PHE = plates
(9) AX = axial-flow fan
