This invention optimizes the settings of refrigeration components to achieve a power efficient state. First, the compressor is run at a level that achieves a desired temperature. Next, the invention searches for the most energy efficient settings (claimed as operation manipulation amounts) for the fans and indoor expansion valves. The search algorithm tries adjusting the settings of each component by a predetermined amount, adopting the setting that is the most energy efficient for the refrigeration cycle. The algorithm then increases or decreases the predetermined amount, as appropriate, and repeats the search. This allows the invention to quickly and accurately converge on the most energy efficient setting for each component.
