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 under normal working condition: water flow 0.172 m
3
/(h•kW), outlet water temperature of chilled water is
7℃,air inlet temperature of condenser is 35℃;
2. heating mode under normal working condition: water flow 0.172 m
3
/(h•kW), outlet water temperature of chilled water is
45℃,air inlet temperature of condenser is DB/WB 7/6℃.
