Abstract
An operation method and an operation apparatus for multi-system refrigerators, and a refrigerating apparatus. When gas compressed by a single compressor is supplied to a plurality of refrigerators through valves provided for the individual refrigerators, the opening/closing frequencies of the individual valves are slightly shifted to one another. As a result, with a simple constitution, the performances of the individual refrigerators are balanced without observing valve timings.
