PROBLEM TO BE SOLVED: To provide a method for operating an air conditioning system and an air conditioner which can contribute to the realization of an ideal temperature environment without deteriorating the features of one inlet and two outlet type indoor machine. SOLUTION: An air conditioner comprises an indoor machine which is used and disposed in the vicinity of a floor surface and includes an air inlet port 4, an upper air outlet port 6, a lower air outlet port 11, an upper heat exchanger 17, an upper fan 15, a lower heat exchanger 18 and a lower fan 16. The air conditioner is provided with an auxiliary throttle mechanism 19 through which the upper heat exchanger 17 is connected in series to the lower heat exchanger 18 so as to supply a refrigerant in a path from the upper heat exchanger 17 to the lower heat exchanger 18 during a cooling operation, supply a refrigerant in a path from the lower heat exchanger 18 to the upper heat exchanger 17 during a heating operation and a control means 32 for controlling either the auxiliary throttle mechanism 19 or a main throttle mechanism 26 so as to supply from the upper air outlet port 6 air at the temperature lower than that of air supplied from the lower air outlet port 11 at least during the cooling operation and heating operation. |
