HVAC and Plumbing Expert Witness, Russ Keeler -- How Can Ice be Used to Create More Efficient Air Conditioning Systems While Building Smaller Chiller Plants?

Russ Keeler specializes in forensic investigations for HVAC and Plumbing cases, serving attorneys nationwide as a Plumbing and HVAC Expert Witness. Today's question, "How can you save space and money on Air Conditioning, using Ice Based Thermal Storage?"

by John Gaudio,

How can you use ice like a battery, for more efficient air conditioning?  Russ Keeler knows.

"Ice based thermal storage is an excellent means to reduce the size of an air conditioning cooling plant. This is achieved by providing undersized water chillers capable of producing chilled water at low temperature (22-24F).  The typical cooling load of a building shows that the peak design cooling is only required for a few hours in the afternoon.  Thermal storage acts as a “battery”, which creates ice during minimal load hours at night, then melts that ice during the peak daytime hours. 

Successful installations have reduced the size of the chiller plant by up to 40%, and saved a significant part of the electric demand cost, with no loss of comfort.  It's also a green solution, as nighttime electric production uses the most efficient part of the generating system.  Care must be taken in design; many systems have failed due to overly complex control systems."
