<P>PROBLEM TO BE SOLVED: To provide a multi-room type air conditioner which improves temperature adjustment accuracy of room air by enhancing detection accuracy of a sucked air temperature while preventing shortage of a refrigerant and suppressing overheat. <P>SOLUTION: The multi-room type air conditioner adopts an operation method in which a small amount of the refrigerant is made to flow in an indoor unit of which a thermostat is turned off or which is stopped to prevent the shortage of the refrigerant when the indoor unit, of which a thermostat is turned off or which is stopped, and the indoor unit, of which a thermostat is turned on, are mixed in heating operation of a plurality of indoor units connected to a same outdoor unit. When the indoor unit of which the thermostat is turned off, and the indoor unit of which the thermostat is turned on are mixed during heating operation of the plurality of indoor units, a blower is operated in wind speed patterns structured of two or more wind speeds including a wind speed higher than a minimum wind speed which can be selected manually and a wind speed lower than the minimum wind speed which can be selected manually when a temperature of the heat exchanger of the indoor unit, of which the thermostat is turned off, is higher than a first predetermined temperature (T1). <P>COPYRIGHT: (C)2012,JPO&INPIT |
