Title:
FREEZING APPARATUS
Document Type and Number:
Japanese Patent JP2006266653
Kind Code:
A
Abstract:
To prevent reduction of recovering power of an expander 12 and to control high pressure of a refrigerant circuit 10 with high accuracy even under an operating condition where sucked refrigerant of a compressor 11 becomes less dense, in a refrigeration device 1 where the expander 12 and the compressor 11 are mechanically connected.
A first bypass passage 20 is connected with a discharge side 18a of the compressor 11 and an inflow side 18b of the expander 12, and a first bypass flow rate adjusting mechanism 21 capable of adjusting a flow rate of the refrigerant, is mounted on the first bypass passage 20.
