Abstract: The subject invention pertains to a method and apparatus for an orientation independent compressor. The subject compressor can be part of a vapor compression cycle system, and can use one or more of a variety of working fluids, including, but not limited to, refrigerants such as r-134a, r-22, CO2, and NH3. Embodiments of the compressor can utilize positive displacement apparatus to compress the vapor. In a specific embodiment, the compressor can incorporate an oil-lubricated rotary lobed type positive displacement compressor. In a further specific embodiment, the working fluid vapor can be a refrigerant, such as r-134a, incorporating entrained oil, such as miscible lubricating oils. An example of such a miscible lubricating oil that can be used is polyester (POE) oil.

Abstract: The subject invention pertains to a method and apparatus for heating exchanging. In various embodiments, the application of coating, plating, soldering, and brazing technologies can be used to create high performance heat exchangers. Specific embodiments of the subject heat exchanger can be lightweight and resistant or impervious to oxidation and/or corrosion. Specific embodiments of the subject heat exchanger can be highly manufacturable. Embodiments of the subject invention are directed to a heat exchanger that includes primarily, but not necessarily entirely, components or assemblies that are made from aluminum and/or aluminum alloys, and are coated or plated with a more oxidation and/or corrosion resistant metal. The coated or plated aluminum components or assemblies can be specifically resistant to corrosion or oxidation in the presence of water or water based solutions and mixtures.
