Abstract:
1. A cooling system comprising: at least one facility cooling unit, the at least one facility coolant unit comprising a heat dissipation coolant loop, wherein facility thermal energy is extracted by the at least one facility cooling unit and expelled to coolant of the heat dissipation coolant loop; a cooling tower in fluid communication with the heat dissipation coolant loop, the cooling tower comprising a liquid-to-air heat exchanger for expelling thermal energy from coolant of the heat dissipation coolant loop to the surrounding environment; at least one thermal capacitor unit controllably in fluid communication with coolant of the heat dissipation coolant loop to facilitate efficient thermal energy transfer from the coolant of the heat dissipation coolant loop to the surrounding environment with variation in ambient temperature about the cooling tower, the at least one thermal capacitor unit comprising at least one actively controlled thermal capacitor unit controllably in fluid communication with the coolant of the heat dissipation coolant loop to either pass coolant of the heat dissipation loop through the at least one actively controlled thermal capacitor unit or to bypass the at least one actively controlled thermal capacitor unit, and wherein the at least one actively controlled thermal capacitor unit comprises at least one cold coolant storage unit and at least one hot coolant storage unit, the at least one cold coolant storage unit being controllably in fluid communication with the heat dissipation coolant loop between a coolant outlet of the cooling tower and a coolant inlet of the at least one facility cooling unit, and the at least one hot coolant storage unit being controllably in fluid communication with the heat dissipation coolant loop between a coolant outlet of the at least one facility cooling unit and a coolant inlet of the cooling tower.
