Ice Bear 30 Hybrid Air Conditioner

Have you ever noticed in the rate section of your electric bill that you pay a significantly higher rate per kilowatt hour (kWh) during what the utility calls “peak hours”? If you are on a “Time-of-Use” rate the electric utility company charges you a premium per kWh consumed during hot summer days when everyone is using air conditioners and the demand for electricity is skyrocketing.

This peak hour usage accounts for a majority of most peoples annual electric costs, depending on how much you use your air conditioners. Typically air conditioners are the largest load on your electric service, therefore commercializing an efficient air conditioner is the holy grail of energy efficiency. I have wrote about the GreenCore PV Powered Air Conditioner and the AC Sun solar thermal air conditioners in the past, although the Ice Energy‘s Ice Bear 30 Hybrid Air Conditioner uses Ice, the same type that comes out of our refrigerators as a storage method for cool air.

The Ice Bear 30, is a piggy back unit that connects to most air conditioning systems and requires no modification to existing duct work or structure, Ice Bear hybrid A/C unit integrates seamlessly with the conventional 3-10 ton rooftop and split-system air conditioners that cool most light-commercial and residential buildings.


Now this is the “cool” part, quite literally. The Ice Bear 30 stores cooling energy at night, when electricity generation is cheaper per kWh, cleaner and more abundant, by freezing water within an insulated storage tank to create and storing cooling capacity for the next day.

During the day, the Ice Bear, using the energy stored the previous night to provide cooling by circulating chilled refrigerant from the tank to a modified evaporator coil within the conventional air conditioning system.

Ice Energy already has Ice Bear 30 units successfully installed, the company is manufacturing product and setting up their distribution network, which is great to hear because most companies in the “smart air conditioning” space do not yet have a product to offer to the public.

You maybe thinking, how is this post related to solar photovoltaic panels or solar energy in general. Well its always better to “Reduce then Produce” as a strategy to get the most out of your solar power system. Many times a solar power system will require too many panels to offset your total usage because your home or business is energy inefficient. Products such the Ice Bear 30 combined with a solar power array could be a very cost effective and reliable application of solar energy production and energy efficiency. What do you think?
