The Tun WAN Hall is a large hall for public events. During an event, the hall needs to be cooled effectively by using circulating chilled water at the Air Handling Unit (AHU). The AHU consists of a compact, crossflow, heat exchanger. As shown in Figure Q3B, the chilled water flows into the AHU at 1.5 kgs and 6C. Hot air from the hall (ambient air)
