The present invention provides a cooling system with supplemental thermal storage. The cooling system comprises a compressor, an evaporative condenser, a thermal storage unit, and an evaporator. During normal outdoor temperatures when building cooling is desired, the compressor output is connected to the evaporative condenser which in turn is connected to the evaporator coil. During periods of time when the building is not occupied, the evaporator coil is removed from the cooling circuit and the working fluid passing through coils in the thermal storage unit acts to freeze liquid surrounding the coils within the thermal storage unit tank. During unusually warm outdoor temperatures, when additional building cooling is required, the compressor output is connected to the evaporative condenser which in turn is connected to the thermal storage unit which output is in turn connected to the evaporative coil. During such operation, additionally chilled working fluid is provided to the evaporator coil due to the working fluid passing through the coils of the thermal storage unit and thereby being further chilled due to the frozen liquid surrounding the coils in the thermal storage unit.

A method of cooling air comprising the steps of passing a working fluid through a compressor means, then passing the working fluid through a condenser means, then passing the working fluid through a receiver means, then operating in one of three modes, wherein the first mode includes the further steps of passing the working fluid as a liquid from the receiver means through an expansion device to form a gas-liquid two-phase mixture of the working fluid, and then passing the two-phase mixture through an evaporator means to cool air passing through the evaporator means and change the working fluid into a gas and then passing the working fluid back to the compressor means, wherein the second mode includes the further steps of passing the working fluid as a liquid from the receiver means through an expansion device and then into tubing passing through thermal storage means to freeze a phase change material therein and change the working fluid to gas and then passing the working fluid back to the compressor means, and wherein the third mode includes the further steps of passing the working fluid as a liquid from the receiver means through the tubing in a thermal storage means having a frozen phase change material therein to further chill the working fluid liquid in the coil by melting said phase change material, passing the working fluid liquid through an evaporator means to cool air passing through the evaporator means and change the working fluid into a gas and then passing the working fluid gas back to the compressor means.
