HEAT SOURCE CONTROLLING METHOD AND HEAT SOURCE CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce operation cost and unify accumulated operation time for each of heat source devices. SOLUTION: An accumulated operation time of each of cold water devices (a heat source device) is calculated (a step 102). A running cost of each of cold water devices is calculated (a step 103). It is checked whether or not there is a cold water device in which a difference Δt in respect to a maximum accumulated operating time exceeds a predetermined time T (Δt>T) and if the cold water device with Δt>T is present, a priority order is applied in sequence of running cost to the cold water device with Δt>Tf (a step 105). Then, it is checked whether or not the cold water device with Δt<=T (a step 106) and a priority order is applied in a next sequence in an order of an operation cost (a step 107). A control over the number of operation of the cold water devices is performed in accordance with the applied priority order.
