Due to the nature of subdivision of the cooling loads in the building, it was decided to provide two VRF systems for the ground floor and first and second floors respectively. Thus, the selection criterion of two separate systems has been based on the two cooling demands: 93 kWh and 88 kWh (35 kWh + 53 kWh).

The Fujitsu Airstage V-2 outdoor condenser units were considered suitable as they can deliver first-class energy efficiency and reliability. Figure 13 shows the technical data of two condenser units provided by Fujitsu.
