Thermal Ice Storage Systems

Using ice to provide cooling has been common for hundreds of years. The ice man was a common site on many city streets even as late as the 1940’s. “Modern theatres in the late 1800’s that advertised air conditioned comfort used ice blocks cut from northern lakes the previous winter.

Both ice on coil and ice ball type thermal storage tanks provide off peak cooling and load shedding application possibilities. Ice is built in tanks during off-peak of low load periods and used to provide part of all of the chilled water during on-peak power or peak load periods.

Ice Kube Systems manufacturers water-to-water heat pumps designed to operate efficiently at temperatures as low as 10°F (-12°C). The heat pumps produce chilled water to build ice in the tanks while making warm fluid that can heat the building, preheat domestic water, provide radiant heat for snow melt, use your imagination.

Many commercial buildings, even in Canadian winters, require cooling during the afternoon solar, equipment and personnel heat loads. During these time periods heat can be taken from the ice storage tanks at night while building ice and heat the building. The ice that is built the previous night is then used for air conditioning the next day. This simultaneous use of the heat pump nearly doubles its operating efficiency. This also minimizes mechanical equipment run time during the higher electrical rates if time of day billing is available in your area.

Thermal ice storage can also be used for peak load shaving. A prime example is a church or other facility that has a large daily or weekly imbalance in cooling loads. Mechanical equipment can be installed to handle the base load of the facility and the thermal ice storage can be used to shave off the peak load. This will allow the mechanical equipment, electrical service, ground loop, circulation pumps and ancillary equipment to be downsized with less mechanical equipment installed saving capital costs.
