Abstract
A complex fluid machine (100) comprises a compressor device (110) for a refrigerating cycle (20) and an expansion device (120) for Rankine cycle (30) to collect waste heat from an engine (10) and convert into a rotational force, wherein the compressor device (110) and the expansion device (120) are arranged in a fluid machine housing (111, 101c, 121), but those devices (110, 120) are operatively independent from each other. The compressor and expansion devices (110, 120) are formed as scroll type devices, and each of the fixed scroll wraps (112b, 122b) are formed at a common base plate (101) and extend in opposite directions.
Claims9
complex fluid machine comprising:
- a compressor device for a refrigerating cycle for compressing and pumping out working fluid upon receiving a driving force from an outside driving source;
- and
- an expansion device for a Rankine cycle for generating a driving force by expansion of working fluid in the Rankine cycle;
- wherein the compressor device and the expansion device are formed as scroll type devices and independently operated from each other,
- each of the compressor device and the expansion device has a non-orbiting scroll, and the compressor device and the expansion device share a common base plate,
- the non-orbiting scroll of the compressor device has a first non-orbiting scroll wrap formed at and extending in one direction from the common base plate,
- the non-orbiting scroll of the expansion device has a second non-orbiting scroll wrap formed at and extending in the opposite direction from the common base plate,
- the compressor device further has a first orbiting scroll wrap intermeshed with the first non-orbiting scroll wrap to form a first working chamber, and
- the expansion device further has a second orbiting scroll wrap intermeshed with the second non-orbiting scroll wrap to form a second working chamber.
