<p><P>PROBLEM TO BE SOLVED: To provide an air conditioning system having a plurality of heat source machines and capable of utilizing the control of the number of operated heat source machines in minimizing coefficient of evaluation to increase the efficiency related to saving of energy consumption. <P>SOLUTION: This air conditioning system controls the number of operated heat source machines to set the number of a plurality of operated heat source machines in accordance with load specified by the air conditioning conditions. A method for controlling the number of operated heat source machines comprises a process for obtaining the coefficient of evaluation by simulating the operation of current number of heat source machines by the current number of heat source machines, a process for determining the possibility or the impossibility of operation and obtaining the coefficient of evaluation by simulating each of the operation by the reduced number of heat source machines for reducing by the predetermined unit number of heat source machines more than the current number of heat source machines, and a process for increasing or decreasing the number of operated heat source machines by only the unit number of them on the condition that the coefficient of evaluation of the operation by the increased number of them or the coefficient of evaluation of the operation by the reduced number of them is smaller than the coefficient of evaluation of the operation by the current number of them and the operation by the increased number of them or the operation by the reduced number of them is determined to be possible in the preceding process. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
