Abstract

PURPOSE: To make possible an optimum air conditioning operation at all times irrespective of the number of operation rooms by a method wherein two-way valves connected to the input and output sides of a heat exchanger in non-operational indoor device are constituted to be opened and closed controllably in accordance with the operational condition of a refrigerating cycle.
CONSTITUTION: When a controller 8 receives a signal, which indicates the shortage of refrigerant, from a temperature sensor 7, a two-way valve of one of other indoor devices, for example, a two-way valve 52c of an indoor device 52 is opened by a predetermined period of time and is controlled so as to lower an outlet temperature by the supply of the refrigerant. When the short state of the refrigerant still continues under this condition, the two-way valve 52c is opened again by a predetermined period of time in the same manner and is controlled so as to repeat this method several times at regular intervals until the outlet temperature is lowered down to a detected temperature or below. On the contrary, when the outlet temperature is too low and it is indicated that the refrigerant is in an excessive state, a two-way valve 52b on the inlet side of a heat exchanger 52a is brought into an open state by a predetermined period of time to accumulate the excessive refrigerant into the indoor device 52 so that the outlet temperature is increased to secure the optimum operation of an air conditioner.
