Abstract
An apparatus for managing operation of refrigerating machines controls defrosting of evaporators of refrigeration cycles. Each of the refrigeration cycles uses a compressor, a condenser, a decompressor, and the evaporator, and is formed for a corresponding one of cooling/heating devices installed in a single store. The apparatus obtains a total estimated power consumption in a case of a pull-down operation using power consumptions necessary for the pull-down operation performed for the cooling/heating devices after defrosting is performed and using a power consumption of the store that includes at least the power consumptions of the refrigeration cycles and that is estimated for each of predetermined time periods. The apparatus changes defrosting start times or defrosting end times of the cooling/heating devices so that the total estimated power consumption does not exceed an upper limit value of a power consumption set in advance by the store.
