A dual cycle water chiller or refrigerating system including both a compression-type (mechanical) refrigerator unit and an absorption-type refrigerator unit; further, having a condenser so configured and arranged as to power the absorption cycle substantially entirely from the heat rejected from the compression cycle. The compression and absorption units share a common hermetic housing. Moreover, the system in accordance with the invention involves a dual circuit evaporator whose elements contain the fluid to be cooled for both the compression and absorption units, these elements being so arranged that the fluid to be cooled is acted upon first by the absorption unit, and then by the compression unit, thus optimizing the operational characteristics of each cycle.
