Zusammenfassung:	PROBLEM TO BE SOLVED: To provide the motor of a closed liquid refrigerant pump for an ice thermal storage type air conditioning system. SOLUTION: The pump part 11 of the closed liquid refrigerant pump 1 and the motor part 12 thereof are separated from each other by pressure, and also a returning piping 6 returned from an interior heat exchanger 8 to an ice thermal storage tank 2 is connected to the motor part 12 so that the whole evaporated refrigerant gas is passed through the motor 12, thus the exothermic action of the motor is absorbed and the efficiency and reliability thereof can be secured. A sufficient amount of refrigerant gas is supplied so that abnormal heating can be prevented, and liquid refrigerant may not be brought into contact with a motor winding so that there is no fear of a current leakage.
