摘要

The refrigerating circuit device (100) has a refrigerant circuit (110) with a compressor (111) for compressing refrigerant in high temperature and high pressure refrigerant, and for discharging the compressed refrigerant. The compressor discharges an adjustable output quantity. A controller (120) controls output quantity of the compressor. The controller reduces output quantity of compressor, if number of revolutions of the compressor is larger than a given number of revolutions, such that output quantity is smaller than maximum value, which is defined according to the number of revolutions.
