Argo FCW01 - Working Conditions

Fan Coil Unit Wall Mounted Type
1.3 Working Conditions
(1) The entering water temperature for cooling is suggested to be no less than 5
℃
,otherwise it woule lead
to condensate; the entering water temperature for heating is suggested to be not higher than 60
℃
,
otherwise it would lead to corrosion of copper tubes or abnormal noise.
(2) The suggested working environment temperature for cooling ranges 16
～
40
℃
and ranges 10
～
30
℃
for heating. Beside, the relative humidity is or less than 80%.
(3) This product is a kind of comfort air conditioning, and is not allowed to be installed where there are
corrosive, explosive and inammable substances or smog; otherwise it would lead to operation failure,
shortened service life, ve hazard or even severe injuries. Special air conditions are required for where
mentioned above.
(4) The A-weighted sound pressure level is below 70dB.
(5) The temperature exchange efciency and enthalpy exchange efciency are tested under these testing
conditions as below:
y
Cooling capacity: air 27°C DB , 19°C WB, water temperature intake 7°C, outlet 12°C.
y
Heating capacity: air 20°C DB , For the tow-row coils applicable to EU, the entering/leaving water
temperature is 45°C and 40°C; and for the four-row coils, the entering/leaving water temperature is
65°C/55°C.
y
Freeze-up : air 27°C DB, 24°C WB , water temperature 6°C intake , 10°C outlet .
y
Sound power level according to ISO 5151. Sound pressure level are calculated at the below of air-
outlet 1m and 1m distance. The noise are tested before leaving factory.
