Commercial Applications • Ice Bears 30’s are combined with packaged HVAC • The Ice coils are inserted into the packaged HVAC units • 1 Ice Bear can support multiple packaged units • Paired with 3 to 20 Ton Package Units
Residential Applications • Ice Bears 10 & 20’s completely replace AC compressors • Ice Bears provides 24/7 cooling and energy storage • Significant dehumidifier – reduces potential mold issues • Apply to ductless mini-splits or traditional ducted systems • 2.5 to 5 Ton AC compressor replacement
Ice Bear Thermal Energy Storage Applications!

Hawaiian Market Observations and feedback from HECO !• Transporting fossil fuel to HI islands to generate electricity is expensive and
is a significant carbon emitter • High cost of electricity and carbon reduction interests drove rapid adoption
of Solar PV and Wind generation resources • Renewables have created new challenges for HECO, the “Duck Curve” • Trade winds and hotter weather patterns have increased air conditioning
needs • Air conditioning is a standard home appliance and humidity control system • Electric battery operating characteristics and costs are not aligned with
residential air conditioning energy usage and heavy duty cycles • Interconnecting thousands of residential batteries creates challenges

Solar PV + Thermal Energy Storage !NetZero operation experience since 2012!
• HI school classroom Solar/Storage application example
• Charge Ice Batteries using off peak energy or use Solar PV to make Ice.
• Federal Investment Tax Credits for Ice Bear when Ice is made with Solar PV
