1. An air conditioning system comprising:

  • a condensing unit;

    a liquid pressurizer and distributor ensemble;

    a cold thermal energy storage unit;

    at least one target space; and

    a suction gas equalizer and distributor ensemble comprising at least one cold thermal energy storage unit in fluid communication with the cold thermal energy storage unit, and at least one target space expansion valve in fluid communication with the at least one target space;

    wherein;

    the condensing unit, the liquid pressurizer and distributor ensemble, the cold thermal energy storage unit, the target space, and the suction gas equalizer and distributor ensemble are operatively connected by piping such that in at least one operational configuration vapor compression cycles are simultaneously implemented that result in cooling of the cold thermal energy storage unit and the target space;

    the air conditioning system is configured such that in the at least one operational configuration where the vapor compression cycles are simultaneously implemented that result in cooling of the cold thermal energy storage unit and the target space, the cold thermal energy storage is cooled to a temperature lower than that of the target space; and

    the suction gas equalizer and distributor ensemble is configured to direct flows of a working fluid having different pressures from the cold thermal energy storage unit and the at least one target space and equalize the at least one target space to a common suction gas pressure.
