<p><P>PROBLEM TO BE SOLVED: To prevent degradation of coefficient of performance (COP) of an air conditioner 10 by minimizing power consumption of a compressor 21 to obtain necessary heat exchanging performance in each indoor heat exchanger 27, in the air conditioner 10 comprising a refrigerant circuit 20 having the plurality of indoor heat exchangers 27. <P>SOLUTION: A controller 1 for controlling an operation of this air conditioner 10 is provided with a calculating means 4b for calculating an optimum value of a refrigerant outlet supercooling degree from each supercooling degree calculated with each control function determined by each indoor heat exchanger 27 to maximize the coefficient of performance, and a changing means 5 for changing a set temperature Tcm to make a representative value determined on the basis of a target supercooling degree SCs of each condenser 27 close to the optimum value. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
