R-134a is not a viable solution for small unitary air conditioners. HFC refrigeration systems must always have a drier with 3 Angstrom Molecular Sieves. The temperature/pressure characteristics are different for each type of refrigerant. Secop has been a pioneer and early adopter of hydrocarbons as refrigerants and believes the most efficient and economical friendly substances for use in cooling appliances are isobutane (R600a) and propane (R290). R600a and R290 are hydrocarbons. In conclusion, I feel the R600 has the top hand here with R 290 following and deeply feeling they should phase out the R134a … Two properties are critical: the ozone depleting potential (ODP) and the global warming potential (GWP).

R134a, R227ea, R245fa, R600a, Pentanes: Compatible lubricants: Environmental Impact. The … R-134a had the benefit of not containing Chlorine so with its usage there would be no danger to the Ozone layer. R-600 goes to have a lot of advantage in making the R-134 less valuable. Greasy substances and other long-chained, high molecular substances not dissolved must not be present.Manufacturing processes which require a lubricant can be done with Polyester oil approved for the compressors.Procedures for mounting, evacuation and charging must be carried out in such a way that contamination with chlorine refrigerants is avoided. Son utilisation n'endommage pas la couche d'ozone et permet de travailler à des pressions plus basses que le reste du HFC. Secop compressors for the flammable refrigerants R600a and R290 are equipped with a yellow warning label as shown. Instead of pasting a large table of information here I will instead direct you to our specific R-600a refrigerant temperature page. Refrigerator. As long as the compressor was working well, it could be drained, filled with R134a-compatible oil, and reused. (To cover potential risk originated from the use of flammable refrigerants). The different compressor brands contain different amounts of oil, so when converting to another brand it may be advisable to correct the amount of refrigerant. The refrigerant charge must be made with the compressor running, the refrigerator without load, and with the door closed. Instead of … The significant downside of HFC refrigerants is their high global warming potential since they belong to the category of greenhouse gases. This has a boiling point of -26.20C which bears reasonable comparison with the boiling point of R-12 (-29.80C). Systems with an expansion valve must be charged with refrigerant until there are no bubbles in the sight glass, which should be placed as close to the expansion valve as possible.

The HFO (hydrofluoroolefin) R1234yf can be used as drop-in for replacing R134a in the short-term for most of the applications. It does not seem to be compatible … This can be found by clic… The other new alternative to R134A is HFO-1234YF, which has similar properties to R134A but meets the new European global warming standards. Il en est de même pour le 134, qu’il ne faut pas confondre avec le R134a. R600a and R290 are heavier than air and the concentration will always be highest at the floor. Compared with CFCs, HCFCs and hydrofluorocarbons (HFCs), HCs offer zero Ozone Deple-tion Potential (ODP) and extremely low Global Warming Potential (GWP) and, in regard to their performance, they offer in general: high efficiency, reduced charge sizes, and a range of other benefits such as mineral oil compatibility. R600a (Iso-Butane) is a hydrocarbon that is becoming increasingly popular due to its low Global Warming Potential (GWP). R600a is suitable for new R600a systems. Other alternatives / replacements: R290, R1270, R134a: Compatible … Refrigerant R600a is mainly used with mineral compressor oils, so material compatibility is al-most identical to R12 in terms of oil. one can use a R134a compressor instead of R600a compressor with the same cycle but one should not use a R134a compressor with R600a refrigerant.

Conversions from refrigerants R12 or R134a to R600a is not permitted, as the refrigerators are not approved for operation with flammable refrigerants, and the electrical safety has not been tested according to existing standards either. Before this amendment, the United States and the EU had introduced regulations to define the phase down and replacement of these HFCs on a federal level. Charge of refrigerant can be made by weight or volume. If the charging amount is unknown, charging must be done gradually until the temperature distribution above the evaporator is correct. Use the ‘, A-Gas product cylinders are fitted with a, Store cylinders in a cool, dry, well ventilated area, out of direct sunlight, R600a (Iso-Butane) is fitted with a left handed DIN 477-1 valve, A-Gas operates a returnable cylinder fleet, empty cylinders are to be returned to an A-Gas wholesale partner, The 420g can is a non-returnable cylinder and does not need to be returned to an A-Gas Wholesale partner.
