Ice Kube Low-temperature Water-to-Water Heat Pumps

Ice Kube Systems specializes in water-to-water heat pumps used in low-temperature applications. Geothermal or ground-source heat pumps are designed to operate efficiently with source (ground) temperatures of approximately 30 deg. F (-1 deg. C). The lower the source temperatures, the less efficient the heat pumps.

Ice Kube Systems has maximized the efficiency of the water-to-water heat pumps in several ways:

• Increase the size of the evaporator and condenser
• Insulate the evaporator and condenser
• Maximize the efficiency of the evaporator
• Optimize the size of other system components
• Use refrigerant designed to operate at low temperatures
• Optimize system design

Ice Kube Systems Low-temperature Water-to-Water Heat Pumps rated in accordance with ARI/ISO 13256-2

These heat pumps are designed to operate at lower temperatures than typical geothermal or ground-source heat pumps. They are designed to operate efficiently at temperatures as low as 10 deg. F (-12 deg. C), and will operate effectively at temperatures as low as 0 deg. F (-18 deg. C)

The efficiency at low temperatures, combined with appropriate system design, makes these systems very effective at making ice in hockey and curling rinks. With good system design, the heat pumps will provide space heating and domestic hot water for the entire facility, and in many cases, to other nearby buildings.

Many large commercial buildings such as office buildings, schools, churches, and many manufacturing facilities that require process cooling can benefit from using thermal ice storage systems. The system can be designed to make ice in storage tanks at off-peak hours while heating the building with energy taken from the ice. This can effectively heat a building during the night while supplying capacity for the next day's air conditioning. This can almost double the coefficient of performance of the entire system, when viewed over a daily charge and discharge cycle.
