The present invention provides a cooling system with supplemental thermal storage. The cooling system comprises a compressor (12), an evaporative condenser (20), a thermal storage unit (40), and an evaporator (80). During normal outdoor temperatures when building cooling is desired, the compressor (12) output is connected to the evaporative condenser (20) which in turn is connected to the evaporator coil (86). During periods of time when the building is not occupied, the evaporator coil (86) is removed from the cooling circuit and the working fluid passing through coils (46) in the thermal storage unit (40) acts to freeze liquid (50) surrounding the coils (46) within the thermal storage unit tank (52). During unusually warm outdoor temperatures, when additional building cooling is required, the compressor (12) output is connected to the evaporative condenser (20) which in turn is connected to the thermal storage unit (40) which output is in turn connected to the evaporative coil (86). During such operation, additionally chilled working fluid is provided to the evaporator coil (86) due to the working fluid passing through the coils (46) of the thermal storage unit (40) and thereby being further chilled due to the frozen liquid (50) surrounding the coils (46) in the thermal storage unit (40). |
