Abstract
A low-temperature storage of the invention has N refrigeration units that may be used for independently refrigerating N chambers, and a controller having N sets of temperature region setting means and corresponding N temperature settling means usable for N refrigeration chambers. Each of said temperature region setting means comprises a plurality of temperature control switches which may assume a combination of ON and/or OFF states for establishing a desired temperature region in an associated chamber. Furthermore, within respective temperature regions, desirable temperatures may be preset by associated temperature setting means. When the number chambers available is less than N, said controller may be used for controlling an arbitrary number of refrigeration chambers in a desired combination of modes by setting non-used set of said temperature setting means in prohibited mode.
