Abstract

A refrigeration storage has a function by which, when a refrigerating capacity obtained only by the operation of an inverter compressor (32A) in a first refrigeration circuit (31A) is insufficient, a constant speed compressor (32B) in an independently provided second refrigeration circuit (31B) can be additionally operated. The constant speed compressor (32B) can be activated, however, only when a speed increase instruction is issued continuously four times to the inverter compressor (32A) after the inverter compressor (32A) has reached the maximum number of revolutions. This avoids the constant speed compressor (32B) from being unnecessarily driven, for example, when temperature inside is abruptly changed.
