Scroll Refrigeration Compressors for Aerospace
Scroll Technology for Vapor-Compression Refrigeration
Air Squared has the experience and capability to support unique refrigeration applications with system-level design and custom scroll refrigeration compressors.
Vapor-compression refrigeration is a common refrigeration cycle used in numerous mobile applications, from automobile air conditioning to environmental control systems on board military airframes. A compressor is at the heart of vapor-compression refrigeration systems (VCRS), superheating saturated vapor from the evaporator and circulating it to the condenser, with lubricated scroll and reciprocating compressors being the two most commonly used.
With over thirty years of scroll design experience, the Thermal Systems Group at Air Squared is uniquely positioned to support VCRSs with a range of unique scroll solutions.
- Oil-free scroll refrigeration technology delivers efficient and high-pressure performance without lubrication. The technology is ideally suited for aerospace and space VCRSs where the zero-gravity or hypergravity environment makes oil circulation challenging.
- Using an Oldham ring or idler shaft arrangement, Air Squared can deliver custom lubricated scroll refrigeration compressors for mobile applications where size and weight are critical.
- With in-house testing capability specifically for refrigeration applications, Air Squared offers various system-level services, including design, prototyping, testing, and data collection.

Vapor-Compression Refrigeration
Experience Matters
Air Squared has developed scroll refrigeration compressors for ground, airborne, and space-bound vapor-compression refrigeration systems.

Following the development of an oil-free scroll refrigeration compressor that is capable of operating in zero-gravity, Air Squared has developed and flight-tested a Zero-Gravity Vapor-Compression Refrigerator (ZVCR) for space-bound food storage. The project is a collaboration between Air Squared, Purdue University, and Whirlpool Corporation.
