Systems and methods in accordance with embodiments of the invention implement air conditioning systems that are operable to establish/maintain a desired temperature for a target space and simultaneously establish/maintain a temperature lower than the desired temperature for the target space for an included cold thermal energy storage unit. In one embodiment, an air conditioning system includes: a condensing unit; a liquid pressurizer and distributor ensemble; a cold thermal energy storage unit; a target space; and a suction gas/equalizer; where the listed components are operatively connected by piping such that vapor compression cycles can be simultaneously implemented that result in the cooling of the cold thermal energy storage unit and the target space; and the air conditioning system is configured such that the simultaneous implementation of vapor compression cycles results in cooling the cold thermal energy storage unit to a greater extent relative to the target space.

A system for conditioning air circulated from an interior of a building includes a refrigerant path, an air-cooled condenser in the refrigerant path, a water-cooled condenser in the refrigerant path that transfers heat from refrigerant in the refrigerant path to the building water, an evaporator in the refrigerant path, and a control system. The control system moves the system between operation of the air-cooled condenser and the water-cooled condenser based upon predetermined system conditions.
