Abstract (en)
A multi air-conditioner (100) for simultaneously cooling/heating room air and a method for controlling the same are disclosed. The multi air-conditioner for simultaneously cooling/heating room air includes: a high-pressure gas pipe (410), a low-pressure gas pipe (430), and a liquid line (420), which are connected between at least one outdoor unit (200) and a plurality of cooling/heating switching sets (300); a flow-regulating valve (260) mounted to a bypass pipe (250) connected between the high-pressure gas pipe (410) and the liquid pipe (420); and a controller (500) for increasing an opening degree of the flow-regulating valve, if a heating rate is not below a reference rate during a heating-biased operation and is equal to or less than a required cooling capacity of an indoor cooling unit during the heating-biased operation.
