<p>Provided are: an air conditioning system configured so that the air conditioning ability thereof can be controlled appropriately by preventing the cavitation of the refrigerant pump; and a method for operating the air conditioning system. The present invention is characterized in comprising: an evaporator for evaporating a refrigerant by exchanging heat with indoor air to be air conditioned; a condenser for liquefying the refrigerant gas formed in the evaporator; a refrigerant pump for delivering the refrigerant liquid formed in the condenser to the evaporator; a refrigerant liquid tank disposed between the condenser and the refrigerant pump and temporarily storing the refrigerant liquid formed in the condenser; first cold water piping for supplying cold water, which is generated by a heat source machine, to the condenser; second cold water piping for supplying the cold water, which is generated by the heat source machine, to the refrigerant liquid tank; a tank liquid temperature sensor for measuring the temperature of the refrigerant liquid within the refrigerant liquid tank; and a control unit for supplying cold water, which is required to condense the refrigerant, to the condenser and supplying cold water to the refrigerant liquid tank so that the temperature of the refrigerant liquid within the refrigerant liquid tank is lower than the temperature of evaporation calculated from the suction pressure of the refrigerant pump.</p> |
