Abstract

PURPOSE: To solve the coolant shortage in a coolant circuit in operation to avoid the lowering in capacity, and maintain a normal operation by determining the valve travel according to the load of an operating indoor unit, and changing the valve travel of the indoor unit at a stop of the heating operation to a higher level than that once determined for every specified time. CONSTITUTION: A motorized expansion valve 8b of an indoor unit 7'b which has been detected as 'stop' by a detecting means 15 whether a unit is in operation or not 15 of each indoor unit is determined as 'full-close' by a valve-travel determining means 20 to be controlled to 'full close' by a valve-travel controller 21b, and a motorized expansion valve 8a of an indoor unit 7'a which has been detected as 'in-operation' is controlled to have a predetermined valve-travel by the valve-travel determining means 20 based on load and frequency to be controlled by a valve-travel controller 21a. At this time, for the motorized expansion valve 8b of the stopped indoor unit 7'b, stop time is integrated by a cold/worm-detecting means 16, the detecting means 15, and a timer 23, the valve-travel thereof is corrected to a greater valve-travel, by a valve-travel correcting means 24 for every predetermined time to be controlled by a valve- travel control means 22b.
