Note:
1. Working conditions for cooling: inlet air temperature - dry/wet bulb 27°C/19.5°C; temperature of inlet/outlet water - 5°C/15°C.
2. Working conditions for heating: inlet air temperature - dry bulb 21°C; inlet water temperature 60°C; water flow - equal to that for cooling
operation.
3. Rated air flow is measured under standard atmosphere using dry coils (dry bulb 20°C).
4. Sound pressure grade and sound level are measured in a semi-silent room as per GB/T 19232-2003.
5. H, M and L represent high, medium and low fan speed respectively.
6. Static pressure refers to outlet static pressure.
7. All performance parameters in the above table are measure with a power supply of 220V~/50Hz.
8. The right/left orientation of connection pipes are exchangeable on site (cooling/heating capacity needs to be multiplied by a correction factor
of 0.93 after exchange).
