<p><P>PROBLEM TO BE SOLVED: To suppress a variation of the operation of mutual outdoor units by the control of rotation speeds of outdoor fans. <P>SOLUTION: The air-conditioning system is equipped with a plurality of outdoor units (3a, 3b, 3c) having compressors (12a, 12b, 12c), outdoor heat exchangers (13a, 13b, 13c) and outdoor fans (16a, 16b, 16c), and connected in parallel with one another, and indoor units (2a, 2b, 2c) having indoor heat exchangers (8a, 8b, 8c). A high pressure side pressure sensor (21a) detects the high pressure (Ph) of a refrigerant of the outdoor unit (3a). The rotation speeds of the outdoor fans (16a, 16b, 16c) are concurrently accelerated and decelerated by a high pressure control means (32) so that the high pressure (Ph) detected by the high pressure side pressure sensor (21a) reaches a target high pressure value (Pta). <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
