Abstract

An air conditioning system for appropriately controlling the air conditioning capacity by preventing occurrence of cavitation of a refrigerant pump and a method of operating the system are provided. It includes an evaporator for vaporizing a refrigerant by exchanging heat with air in a room to be air-conditioned, a condenser for liquefying a refrigerant gas vaporized by the evaporator, a refrigerant pump for feeding a refrigerant liquid liquefied by the condenser to the evaporator, a refrigerant liquid tank disposed between the condenser and the refrigerant pump to temporarily store the refrigerant liquid liquefied by the condenser, first cold water piping for supplying cold water generated from a heat source machine to the condenser, second cold water piping for supplying the cold water generated from the heat source machine to the refrigerant liquid tank, a refrigerant liquid temperature sensor for measuring a temperature of the refrigerant liquid in the refrigerant liquid tank and a control unit for controlling to supply the cold water desired for condensation of the refrigerant gas to the condenser.
