Closed-cycle air refrigeration technology
Air cycle refrigeration Air cycle refrigeration systems use air as their refrigerant, compressing it and expanding it to create heating and cooling capacity. Air cycle is not a new technology. Air cycle or cold air machines were available from companies such as J& E Hall (see picture) in the early 1900s.The system, called Closed Cycle Air Refrigeration (CCAR), was born of a joint R& D project undertaken by Air Products and Toromont Process Systems (Houston, TX). CCAR technology is expected to be a welcomed new source of lowtemperature refrigeration to end markets including the food processing, closed-cycle air refrigeration technology

THE basic technology of refrigeration has not changed much since the 19th century. Refrigerators (and their cousins, air conditioners) work by compressing a fluid and then allowing it to expand.
Lowtemperature technology: Closedcycle air refrigeration. Air Conditioning, Heating& Refrigeration News; , Vol. 205 Issue 10, p11. Reports that Air Products and Chemicals Inc. has introduced a breakthrough technology known as the closedcycle air refrigeration.
Low Temperature Mechanical Refrigeration. Air Products' CCAR (Closed Cycle Air Refrigeration) low temperature mechanical refrigeration system is a new technology that uses high pressure air to produce refrigeration at temperatures ranging from 50C (60F) to 100C (150F).
Refrigeration has had a large impact on industry, lifestyle, agriculture, and settlement patterns. The idea of preserving food dates back to at least the ancient Roman and Chinese empires. However, mechanical refrigeration technology has rapidly evolved in the last century, from ice harvesting to temperature
refrigeration systems can provide ultracold temperatures, but at four times the cost of mechanical refrigeration. CCAR technology is a costeffective alternative for the 70F to 150F niche market, where it is able to deliver ultracold refrigeration at half the cost of cryogens. ClosedCycle Air Refrigeration Technology
Ultimately, Air Products expects the technology, called CCAR (ClosedCycle Air Refrigeration) to be attractive to food and pharmaceutical processors, and in process applications where either rapid chilling or lowtemperature refrigeration is desirable.
I am curious as to whether the engineers are familier with ClosedCycle Air Refrigeration Technology: and if so do you think that it would be a better choice then R 290(propane) I for one don't care much for the possible devestation of an explosion even if the system is located outdoors.
