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 inflammable substances or smog; otherwise it would lead to operation failure,
shortened service life, five 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 efficiency and enthalpy exchange efficiency 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.
