Chilled water system vs air conditioning

WebFor a 1200 RT project, the water-cooled chiller system can be about MYR 600k more expensive than the air-cooled VRF system. As for the operating cost, an air-cooled VRF system is about 15% more expensive than a water-cooled chiller system per RT per year. So, the owner of a 1200 RT building needs to pay additionally about MYR 275k every … WebThe most “traditional” HVAC system selected for large buildings is a chilled water system. With this design a chiller cools water that is delivered to the individual building units to cool the air in the space. This requires pumps, insulated supply piping, and insulated return piping to connect the chiller to the individual units.
