PROBLEM TO BE SOLVED: To provide an air conditioning system driving a heat pump type cooling device even when the outside temperature is very low, and heating. SOLUTION: The air conditioning system includes the heat pump type cooling device A and a circulation device B for heating. A first circulation path 1 of the heat pump type cooling device A has a gas-liquid separator 6 that is disposed between an expansion valve 5 and an evaporator 7, separates a refrigerant supplied from the expansion valve 5 through the first circulation path 1 into a refrigerant gas and a refrigerant liquid, and sends the refrigerant liquid to the evaporator 7 by the first circulation path 1, a bypass path 9 for refrigerant gas that bypasses the refrigerant gas separated by the gas-liquid separator 6 to return to the first circulation path 1, and a selector valve 8 that stops the refrigerant liquid separated by the gas-liquid separator 6 not to be supplied to the evaporator 7. In a warming-up mode, only the refrigerant gas is circulated in a refrigeration cycle. COPYRIGHT: (C)2009,JPO&INPIT
