Document Type and Number:
Japanese Patent JP2013139903
Kind Code:
A
Abstract:
To continue operation without immediately stopping an expander even when a torque current of the expander exceeds a threshold value.
This refrigerating device includes an expander protective means 70 for reducing a pressure difference before and behind the expander 30 or a refrigerant flow rate of the expander 30 when an output current of a generator 32 reaches a predetermined threshold value. The expander protective means 70 is constituted of operations for squeezing a degassing valve 52 of a gas-liquid separator 51, increasing a rotating speed of the expander 30, increasing a fan rotating speed of a radiator 44, increasing opening of an expansion valve 29 and increasing opening of an injection expansion valve 81.
