Abstract (en)
[origin: JP2020034266A] To drive, before a refrigeration cycle is switched between a state in which a specific storage room is cooled and a state in which it is not cooled, components which constitute the refrigeration cycle according to the current state.SOLUTION: A refrigeration cycle control device comprises: an acquisition unit which acquires load variation of a storage room of a refrigerator having a refrigeration cycle incorporated; a decision unit which decides a drive value for driving components constituting the refrigeration cycle according to the load variation; and a drive unit which drives the components based upon the drive value. The acquisition unit constantly monitors the load variation with time in a period in which the refrigeration cycle is switched between a state in which a specific storage room is cooled and a state in which it is not cooled.SELECTED DRAWING: Figure 1
