### Chiller vs VRF System: Cost Installation Maintenance

However, the operating cost of water-cooled chiller systems is lower due to higher energy efficiency. A water-cooled chiller system is about 10% more expensive than an air-cooled VRF system per refrigeration ton (RT). For a 1200 RT project, the water-cooled chiller system can be about MYR 600k more expensive than the air-cooled VRF system.

### Cooling Tower Tonnage - HVAC/R engineering - Eng-Tips

Mar 08, 2008 Most likely it's due to your chillers not working at full capacity. If the cooling tower is rated for say 78 wet bulb and the average wet bulb is around 75degrees or less then the cooling tower should be able to do better then 758 tons and handle the load you have. This from San Diego weather: High temperatures are almost invariably ...

### How do you calculate gpm in a chilled water system?

Mar 12, 2020 A water-chiller refrigeration ton is defined as: 1 Refrigeration Ton (RT) ... The result is the tons of capacity of the cooling tower. What is chiller in HVAC? A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. This liquid can then be circulated through a heat exchanger to cool ...

### Cooling tower - Upgrading Single 60 ton Chiller to double 40 Chillers

Nov 10, 2020 It is a split type of chiller, with the condenser outside and evaporator inside. The reason they are changing to two 40 ton is because they want redundancy and also the one 60 ton chiller cannot maintain water temperature in the summer. (they said they normally need 38deg water to maintain cooling and in the summer it gets up to 44deg).
