Abstract:
An apparatus for managing at least one heat source unit for an air conditioner, comprising:means for analyzing cyclic operation condition of said heat source unit from operating data of said heat source unit, said cyclic operation condition having an operating cycle of operation, dilution and stop; means for averaging said cyclic operation condition for a predetermined period; means for storing said averaged data into a storage unit in time series; means for comparing said data stored in time series with analyzed data of current cyclic operation condition obtained by said analyzing means; means for detecting a variation, with time, in lowering of performance and/or degree of advance of abnormality in said heat source unit on and after start of use of said heat source unit, based on a comparison result produced by said comparing means; means for estimating degree of deterioration of said heat source unit on and after said start of use based on said variation with time; and means for determining maintenance time from a predetermined deterioration threshold value and said estimated degree of deterioration.
