Abstract (en)
[origin: EP2835595A1] An indoor fan of an indoor unit in a thermo-OFF state is operated intermittently while reducing a necessary amount of refrigerant and suppressing an increase in receiver capacity. Provided is a control unit (41) for controlling operation of a packaged air conditioning system (1) in which a plurality of indoor units (7) are connected to an outdoor unit (2). During a heating operation, if an indoor fan (73) of each of the indoor units (7A, 7B) 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, the control unit (41) forms a plurality of groups of the indoor units for matching timings for the intermittent operation of the respective indoor units, shifts the timing for the intermittent operation for each group, and controls assignment of the indoor units (7A, 7B) to the groups so that total model capacities of the indoor units (7A, 7B) that are included in the respective groups and are in a thermo-OFF state become approximately equal to each other.
