Document Type and Number:
Japanese Patent JP2009085189
Kind Code:
A
Abstract:

To provide refrigeration cycle equipment of a power recovery type capable of efficiently recovering expansion energy of a working fluid.

The displacement type expander of a power recovery type includes: an intake port for sucking a working fluid; a working chamber for expanding the working fluid sucked from the intake port by changing a volume of the working fluid; a discharge port for discharging the working fluid expanded in the working chamber; a flow rate varying mechanism for varying a flow rate of the working fluid passing through the working chamber; and an overexpansion preventing mechanism for preventing the working fluid from overexpanding in the working chamber.
