Testing condition:
For 60Hz :
The FCU designed for installation indoor. The environmental temperature is from 5°C to 43°C, water
working temperature is from 7°C to 60°C.
The temperature exchange efficiency and enthalpy exchange efficiency are tested under these testing
conditions as below:
1). Cooling capacity: air 27°C DB, 19.5°C WB, water temperature: intake 7°C, outlet12°C.
2).Heating capacity: air 21°C DB, Water temperature intake 60°C, the water-flow volume is same as
Cooling capacity .
3).Freeze-up : air 27°C DB, 24°C WB, water temperature intake 6°C, outlet 9°C.
4).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.
For 50 Hz :
The FCU designed for installation indoor. The environmental temperature is from 5°C to 43°C, water
working temperature is from 7°C to 60°C.
