<p><P>PROBLEM TO BE SOLVED: To provide an air conditioner having improved operating efficiency while allowing the operation of a capability variable compressor in the way of elongating its life as much as possible. <P>SOLUTION: The air conditioner comprises a master outdoor unit 1a having the capability variable compressors 11, 12 and slave outdoor units 1a, 1c having capability variable or constant compressors. While air conditioning loads are assigned to the compressors 13, 14, 15, 16 of the master outdoor unit 1a and the slave outdoor units 1b, 1c in sequence, the assigned compressors are operated with maximum capabilities. When the total operating capability of each compressor exceeds the air conditioning load, the exceeding component is subtracted from the operating capabilities of the capability variable compressors 11, 12 of the master outdoor unit 1a. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
