Summary

Thermal storage reduces peak demands on air conditioning systems. Experience narrows the choice to single tank stratified water storage or ice storage. The preferred ice system makes ice on coils supplied by low temperature glycol. Melting is by circulating the same glycol through the coils and to the air cooling system. If ice is left unused, it is made up on the next cycle efficiently on the pipe wall, rather than on the outside ice surface. Other systems and the design of effective water storage are discussed. Economy is dependent on power costs and demand limits, but generally storage is economical. Ice enables lower air temperature to be used with larger differentials. This decreases air volume, duct sizes, and fan power. It also lowers room humidity. D.W.H.
