Note:
Please refer to the water flow volume in the above table strictly to design and install.
All the above data is measured base on the following working condition:
1. Cooling mode: water side fouling factor: 0.086m2·°C/kW, chilled water inlet/outlet: 12°C / 7°C, and outdoor ambient temp. of
35°C DB.
2. Heating mode: water side fouling factor: 0.086m2·°C/kW, warm water inlet/outlet: 40°C / 45°C, and outdoor ambient temp.
7°C DB/6°C WB.
