Title:
REFRIGERATING DEVICE
Document Type and Number:
Japanese Patent JP2013139904
Kind Code:
A
Abstract:
To continue operation of an expander even if a refrigerant circulating quantity reduces, in a refrigerating device having a refrigerant circuit connected with the expander for collecting expansion power of a refrigerant.
This refrigerating device includes a refrigerant density adjusting means for reducing density of an inflow refrigerant to the expander 30 when the refrigerant circulating quantity of the refrigerant circuit 10 reduces to a processing flow rate in a minimum rotating speed of the expander 30. The refrigerant density adjusting means is constituted of operations for reducing opening of a flow regulating valve 81, increasing a rotating speed of a radiator fan, and reducing opening of pressure reducing valves 2b, 3b and 4b.
