Ice making heat pumps by ice kube
Ice Kube's water-to-water heat pump was designed for low temperature applications while providing hot water for radiant heating applications. It operates at temperatures low enough to provide refrigeration for artificial hockey and curling ice surfaces. Ice Kube's low temperature heat pumps can operate efficiently at water temperatures of 10°F (-12°C) while providing water hot enough to be used as radiant infloor heating.
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
• Maximize the efficiency of the evaporator
• Optimize the size of other system components
• Use refrigerant designed to operate at all temperatures
• Optimize system design
Ice Kube Thermal Ice Storage
Depending on the system application, commercial or refrigeration,the heat pump can be used for thermal ice storage applications. It will operate efficiently at temperatures required to charge the thermal ice storage tank.
Thermal ice storage has a couple main benefits: load shifting to take advantage of off peak power rates, and peak load shaving in facilities with unbalanced cooling loads. The system design can achieve one or both of the energy saving measures mentioned. A properly designed system can make ice in ice storage tanks at off-peak hours while heating the building with the energy taken from the ice. These simultaneous applications can almost double the combined coefficient of performance of the heat pump.
