The Technology
Shift & Save's Ice Bear® technology works with off-the-shelf commercial air conditioners to cool and save energy. Leveraging the thermodynamic advantages of operating during cooler nighttime temperatures, Ice Bear uses a highly efficient patented refrigeration system to make and store ice at night and then uses the stored ice to cool air conditioner refrigerant during the day. Able to shift 95 percent of the power needed for indoor cooling to off-peak hours, Ice Bear consumes equal or less electricity than a comparable conventional air conditioning system.
The Ice Bear 50 system has a capacity of 50 ton hours of cooling, including 45 latent + sensible and an additional 5 sensible only. The unit provides 7.5 tons of cooling capacity for 6 hours of continuous cooling. Typical configurations are:
- 7.5 ton for 6 hours
- 5 ton for 8 hours or more
- Offloading of 10 ton rooftop unit, where 10 ton unit is oversized due to high rooftop temperatures
- Offloading one stage of a 10, 15, or 20 ton, 2-stage rooftop unit
