Abstract (en)

[origin: EP2835596A1] An insufficient state of refrigerant gas is prevented and a fan of an indoor unit is allowed to perform an intermittent operation in a state in which a thermostat is turned off while preventing excessive heating. A control device (41) for controlling operation of a packaged air conditioning system (1), a plurality of indoor units (7) being connected to an outdoor unit (2) and a flow volume of refrigerant circulating through a refrigerant pipe being regulated depending on opening of an indoor electric expansion valve (72) in the packaged air conditioning system, controls, during a heating operation, the opening of the indoor electric expansion valve (72) in a period in which fan of each of the indoor units (7) is turned off to be larger than the opening in a period in which the fan of the indoor unit (7) is turned on, and to be equal to or smaller than the opening set for noise control if the fan of the indoor unit (7) performs an intermittent operation for repeating ON/OFF operations to stop for a predetermined time after rotating for a predetermined time at a time at which a thermostat is turned off.
