Product Overview

Ice Energy uses a standard 5 ton air conditioner condensing unit to make ice during the evening off-peak hours. Stored ice energy provides cooling during the day when the energy consuming compressor is turned off and replaced with a small 100 watt pump.  The pump moves warm refrigerant through copper coils in the ice energy storage module.  The cooled refrigerant then moves through standard evaporator coils to produce air conditioning. 

Ice Energy is invisible to the user because it acts and feels like an ordinary air conditioner.  The system doesn’t require an expensive engineering or feasibility study and even uses existing thermostats and ducting.  Ice Energy products can operate with existing evaporators and air handlers as well as the new mini-split fan coils.

The unit has two modes of operation known as load shifting and load leveling.  In the load shifting mode, stored ice energy provides 95-100% of the daytime cooling capacity reducing typical peak energy consumption from 5,000 to less than 100 watts.  In the load leveling mode, the ice and condenser work together in a unique two step cooling process.  Daytime peak demand is leveled by up to 70% and overall efficiency improves by up to 30% based on the cooling demand.

Ice Energy products pay for themselves with utility savings due to the dramatic reduction in peak demand and an overall improvement in energy efficiency.  Additional utility savings may also include improved load factor and reduced time of use energy pricing schedules.
