Title:
REFRIGERATION SYSTEM AND CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/051635
Kind Code:
A1
Abstract:
A refrigeration system (20) comprises: a power generator (26); a power generation engine (24); a refrigerator (22); a power conversion device (28); an output control unit (100b); and a characteristic estimation unit (100c) that estimates a refrigerator characteristic of the refrigerator according to the outside air temperature and the temperature of a space to be cooled. The refrigeration system includes an output calculation unit (100d) that calculates, as a target drive output, a drive output at which the energy efficiency of the overall system is optimal on the basis of the refrigerator characteristic estimated by the characteristic estimation unit, an engine characteristic of the power generation engine, and a power generator characteristic of the power generator. The output control unit is configured to control the drive output so as to approach the target drive output calculated by the output calculation unit.
