Can Off Peak Cooling be applied to facilities with a night time cooling load?
Many of our projects have nighttime cooling. A rule of thumb to start with says that if the cooling load is less than 20% of the daytime peak a system can be designed to cool the nighttime load with the ice making system. If that nighttime load is greater than 20% a more effective design may be to install a separate chiller. Many systems have two or more chillers. A large system for a skyscraper might have a very efficient non-glycol chiller for base and nighttime loading. A separate ice system can generate off peak cooling and/or enhance the daytime cooling.
