Abstract
Novel vapor compression evaporative cooling systems which use water as a refrigerant are provided, as are methods for using same. Also provided are novel compressors, compressor components, and means for removing noncondensibles useful in such cooling systems.
Claims30
A low-friction positive displacement compressor comprising at least two compressing components, wherein said compressing components comprise:
- an inner gerotor, an outer gerotor and a housing;
- an orbiting scroll, a stationary scroll and a housing;
- a housing and a piston;
- a housing, a rotor and a sliding vane;
- a housing, a rotor and a flap;
- or an inner drum, an outer drum and a swinging vane, and wherein there is a gap between at least two of said compressing components.
A low-friction positive displacement compressor comprising a gerotor compressor, wherein said gerotor compressor comprises an inner gerotor and an outer gerotor, said inner gerotor disposed within said outer gerotor, each gerotor comprising a plurality of teeth, and wherein said inner gerotor has one less tooth than said outer gerotor, thereby creating a void volume between said inner gerotor and said outer gerotor, and wherein there is a gap between said inner gerotor and outer gerotor.
A low-friction positive displacement compressor comprising:
- an outer drum having an axis;
- an inner drum rotatably disposed in said outer drum;
- a plurality of vanes, each vane having a first end and a second end opposite said first end, said vanes pivotally attached to said inner drum at said first end and having a vane tip at said second end, said vane tips being propelled radially outward during rotation of the inner drum;
- a connecting rod coupled to each said vane tip, said rods maintaining a gap between said vane tips and said outer drum;
- and
- coupling means for causing said connecting rods to rotate about the axis of the outer drum.
