District cooling - Load profile

Specific air conditioning requirements for these installations

» Distric cooling relates to very large installations with high power requirements
» They are subject to relatively high air conditioning needs all the time
» Requirements, more or less permanent overnight (cinemas, restaurants, hotels, hospitals etc. …) can reach more than 40% of nominal load profile.
» The air conditioning demand is the highest during the on-peak hours


Benefits yielded by Cryogel cold storage technologies for such installations

An important minimum load in requested all day long :
» Chillers capacity can be reduced
» Smaller electrical installation
» Lower operating costs due to a reduction in peak utility usage, maintenance and more efficient use of chillers
» Less space required for cooling towers and chillers
» Chillers can be stopped during on-peak hours


How does it apply to your own installation

Base assumptions:
» The minimum cooling capacity represents 40 % of the maximum capacity
» On-Peak hours are from 6.00 pm till 9.00 pm
» Cooling needs are only covered by Cryogel Ice Spray System during peak hours
