Thermal Storage Options for HVAC Systems

With the ever-increasing cost of electricity
and the high demand charges levied by utility companies,
thermal storage for cooling is rapidly becoming
a widely recognized method to lower cooling
costs. There are three maior types of thermal storage
systems:
• Ice Storage: This utilizes the latent heat of
fusion of ice for thermal storage. During off-peak
periods, the refrigeration system is used to
build ice. The ice is melted to produce chilled
water when cooling is required.
• Chilled Water Storage: Chilled water is generated
and stored during off-peak periods and used
for cooling during on-peak hours. Since this
method is based on the specific heat of water
rather than the latent heat of fusion of ice as
in ice storage, it requires about 4 times the
storage capacity of an equivalent ice storage
system.
• Salt Storage: This system utilizes eutectic
salts which freeze and melt around 47°F. Existing
chillers can be easily retrofitted for salt
storage or chilled water storage. For ice storage
systems, a direct refrigerant system or glycol
chillers are suitable.
This paper discusses the details of each system,
their advantages and disadvantages, and application.
