1. A refrigerant-based thermal energy storage and cooling system comprising:

  • a first refrigerant loop containing a refrigerant comprising;

    a first condensing unit comprising a first compressor and a first condenser;

    a first expansion device connected downstream of said first condensing unit; and

    ,a thermal energy storage unit comprising a primary heat exchanger connected between said first expansion device and said first condensing unit that acts as a first evaporator and is located within a tank filled with a fluid, said primary heat exchanger that facilitates heat transfer from said first refrigerant from said first condenser to cool said fluid within said tank;

    a second refrigerant loop containing additional said refrigerant comprising a load heat exchanger connected to said thermal energy storage unit that transfers cooling from said thermal energy storage unit to said load heat exchanger to a heat load;

    a third refrigerant loop containing additional said refrigerant comprising;

    a second condensing unit comprising a second compressor and a second condenser; and

    ,a second expansion device connected downstream of said second condensing unit, and said load heat exchanger connected between said second expansion device and said second condensing unit that transfers cooling capacity of said second condensing unit to said load heat exchanger to a heat load.
