(MCHX: unit with microchannel coils; CuAl: unit with copper/aluminium tube/fin coils)
(1) Outside air temperature 30°C; inlet/outlet temperature of ethylene glycol 30% 15/10°C
(2) Outside air temperature 5°C; inlet/outlet temperature of ethylene glycol 30% 15/x°C
(5) Sound power level obtained from measurements carried out in accordance with standard ISO 3744. Reference conditions: External air tempera-
ture 30°C; evaporator inlet-outlet water temperature 15/10°C.
(6) Sound pressure level measured at a distance of 10 metres from the unit in free field, with directivity factor Q=2. Reference conditions: External
air temperature 30°C; evaporator inlet-outlet water temperature 15/10°C. These values are to be considered approximate and non-binding.
(7) Volume of water contained in the unit when it is working in free cooling mode. If present, the volume contained in the tank should also be consid-
ered.
