Disclosed is a demand shifting thermal storage system employing a heat transfer/thermal energy storage vessel to produce and hold a phase change fluid using an air cooled/water cooled/ground coupled or evaporative condensing unit to generate the cold fluid with a separate and dependent circuit coupled to the indoor cooling load to remove heat from the HVAC or process cooling load using one or multiple indoor coils to absorb heat returning the heat to the thermal energy storage vessel to reject the space heat, cool the space and continue the cycle.
