Ice cream cabinets are one example of a light commercial unit that has widely adopted the use of natural refrigerants such as R-290 (propane) and R-600a
(iso-butane), spurred by Unilever's decision in 2000 to implement a non-HFC purchasing policy by 2005.
Optimized for use with eco-friendly hydrocarbon refrigerants R-290 (propane) and R-600a
(isobutane), the TC compressor delivers an efficiency up to 6.1 EER (1.78 COP).
) has dominated the European refrigerator/freezer sector for the past decade and is being used even in Japan and Korea, while propane (R-290) and propylene (R-1270) are used for heat-pumping applications in Europe (IEAHPC 2002).
ICOR Hot Shot R-414B, a blend of R-22, R-142B, R-124 and R-600A
, is claimed to be 10% more efficient than R-12 and 30% more efficient than R-134A, while being completely compatible with systems using either of those refrigerants.
Refrigerators now are almost all built with compressors using R-134a (about two-thirds of the market) or R-600a
, aka isobutane, which is almost universal in Europe and accounts for about one-third of the global market.
(2000) for mixtures of R-290 with R-600 and R-600A
are overpredicted, especially with the Del Col et al.
Three synthetic polyolester (POE) oils of different viscosity grades (approximately 5, 7, and 10 cSt at 40[degrees]C, respectively) were combined with refrigerants R-134a and R-600a
. In absorption of R-134a in lubricant oil, the liquid refrigerant is heavier than the oil, and the liquid flow field is a result of natural mass convection.
Moreover, they aren't toxic or flammable, like ammonia, nor do they pollute the atmosphere like ammonia ("induced effect") and R-600a
(Isobutane, which reacts with other chemicals to produce smog, and is also flammable).

The AE2 supports traditional HFC refrigerants--R-134a and R-404A--and is also optimized for hydrocarbon refrigerants--R-290 (propane) and R-600a
Those compressors are suitable for many standard hydrocarbons such as R-290 (propane), R-600a
(isobutane) and R-1270 (propylene).
