A multi-mode high efficiency air conditioning system for storing energy and for utilizing the stored energy is provided. The air conditioning system includes these four elements which define the entire system: a condensing unit, a dual-mode indoor cooling coil assembly, a refrigerant and air management assembly and an energy storage assembly. These four elements act in concert to perform the functions of the four principal modes of operation which are ice building, ice transfer, stage 1 cooling and stage 2 cooling. The ice building and ice transfer modes typically take place during electrical off-peak periods. The stage 1 and stage 2 cooling modes typically take place during electrical on-peak periods. When connected to an indoor air fan, the air conditioning unit provides cooling at an energy efficiency ratio (EER) of 12 or better over a 24 hour period during a 95 degree Fahrenheit day.
