ICE BEAR: How it Works
Discover the Power of Ice

Pairing its revolutionary Ice Bear energy storage module with a standard commercial air conditioner, Ice Energy delivers the industry's first hybrid cooling solution specifically developed to reduce air conditioning energy demand for small to mid-sized commercial businesses.

Using thermally efficient, off-peak power to produce and store energy for use the next day, Ice Energy’s Ice Bear delivers superior cooling using just a fraction of the peak energy of conventional systems.

Designed for easy deployment, and requiring no modification to existing ductwork or structure, the Ice Bear integrates seamlessly with the conventional rooftop and split-system air conditioners that cool nearly all light-commercial and residential buildings in this country. Each Ice Bear unit can be applied to a 3-5 ton system, or a single 5 ton stage of a 7.5-20 ton system, providing 30 ton hours of cooling at a load of up to 5 tons.

The Ice Bear hybrid air conditioning system stores cooling energy at night, when electricity generation is cleaner, less expensive and more abundant, by freezing water within an insulated storage tank to create and storing cooling capacity for the next day.
During nighttime energy storage mode, a condensing unit pumps refrigerant through a configuration of copper coils within the Ice Bear. The coils fall in temperature to below freezing.

The water that surrounds these coils also begins to freeze and turn to ice. Once it’s frozen, the condensing unit turns off, and the ice is stored until its cooling energy is needed.

As daytime temperatures rise and the building requires cooling, the energy-intensive compressor of the conventional air conditioning system remains off. Since the Ice Bear uses the cold temperature of the ice to condense the refrigerant, rather than a high-energy-consuming compressor, it needs only a small pump to circulate the refrigerant through the copper coils to a modified evaporator coil within the rooftop unit.

Ice is then refrozen each night and energy stored again when electricity generation is cleaner, more efficient and less expensive.

During off-peak hours, the conventional HVAC system operates as usual.

Together, this unique hybrid system surpasses the overall efficiency and performance of conventional equipment alone.
Daytime air conditioning energy demand – typically 40-50% of a building’s on peak electricity use – can be reduced by as much as 95% from the very first day the Ice Bear energy storage unit is deployed.
