    摘要: A refrigeration cycle apparatus achieves efficient operation by constantly recovering power in a wide operating range. The refrigeration cycle apparatus regulates a pressure of a high pressure side by changing either one or both of an opening degree of the intermediate-pressure bypass valve and an opening degree of the pre-expansion valve on the basis of a density ratio that is obtained from an inflow refrigerant density of the expander and an inflow refrigerant density of the sub-compressor in an actual operating state and a design volume ratio that has been expected at the time of design and that is obtained from a stroke volume of the sub-compressor, a stroke volume of the expander, and a ratio of a flow rate of the refrigerant flowing to the sub-compressor.

    摘要: Disclosed is a positive displacement expander equipped with an expansion mechanism in which power is generated using fluid energy produced while a high-pressure fluid, supplied to a plurality of expansion chambers partitioned by an orbiting scroll or a rolling piston, is being expanded and decompressed. The expander includes a communicating pipe that allows each of the expansion chambers to communicate with an expander discharge side and an opening and closing device disposed on the communicating pipe. When supply of the high-pressure fluid is stopped, the opening and closing device is opened by the time when high and low pressures between each of the expansion chambers and the expander discharge side are equalized, thus stopping the orbiting scroll or the rolling piston at a predetermined position so that an expander obtains sufficient driving force when resuming.
