The Best R22 Refrigerant Alternatives

Since enforcement of R22 phasing out started in 2010 the cost has risen exponentially as every year cruised by. In the year 2015 the cost bounced much higher because of harder import and creation limitations set up by the Federal Government. At the point when the year 2020 hits, which it is rapidly drawing closer, R-22 refrigerant will never again be permitted to be foreign or made here in the United States. In the event that you think the cost is awful now at six-hundred dollars for a thirty-pound barrel simply hold up until the year 2020.

With the value hopping up this way and the shortage of R-22 in the commercial center property holders and entrepreneurs are left with an extreme choice when their ventilation system starts to leak refrigerant.

In under a year time it will be unlawful to top up frameworks with virgin R22 (regardless of whether obtained before the end of 2009), which additionally implies that supplies of R22 likewise can’t be utilized to keep gear running past the end of this current year. Just recouped R22 will be allowed available to be purchased and use after this date.

What do you do, at that point, to supplant R22 in such a short timeframe outline? The size of the issue is minimal shy of overwhelming with a huge number of frameworks right now working on R22. This remarkable refrigerant remains the most broadly utilized gas in the acr business today, with over an expected 100,000 tons being used in Europe.

Amid the progress far from CFCs to HFCs, retrofitting straightforwardly from a CFC (eg R502) to a HFC (eg R404A) was observed to be both expensive and as a rule actually inadmissible.

The oil in the framework should have been supplanted by synthetic ointment, which sometimes was not found to be practical, and there were numerous instances of a damage on the seals.

This is the motivation behind why within time refrigerants were acquainted with supplant CFCs without the necessity to change the oil or change any of the equipment. These transitional substances contained no less than one HCFC segment in the mix which encouraged oil return and empowered plant and gear to be time terminated.


Any substitution for R22 must be non ozone draining which overpowers this kind of compound.

HFCs, for example, R407C, are not solvent in mineral and alkyl benzene oils and new engineered oils have been formulated. These new greases get dampness quickly which can cause extreme issues if not appropriately controlled and are significantly more costly than the customary oils.

Having learnt from the encounters with supplanting CFCs and the issues caused with retrofitting specifically to HFCs, Refrigerant Solutions (RSL) began take a shot at substitutes for R22 which could be utilized with the current ointment in the framework, give a comparative execution to R22 and ,obviously, have a zero ODP.

In finding the best counterpart for R22, RSL, in view of its learning of existing R22 applications, chose condenser weight, vitality productivity and compressor volumetric limit as the major thermo-physical outline criteria.

Ahead of schedule in the improvement it was perceived that these criteria could sensibly be coordinated with those of R22 utilizing conceivably adequate mixes, however that no single mix or liquid could be defined to reflect the execution of R22 over the scope of uses at both medium to high and low temperatures where R22 is usually found.

After impressive research work, RSL chose to create three items as a match to R22 in its fundamental applications. Read more blogs on our website .


RS-44 (R424A)

RS-44 is an immediate drop-in substitution for R22 in air conditioning applications in frameworks with a fine and in addition an extension gadget. There is no compelling reason to change the grease since, as with all the RS arrangement of refrigerants, RS-44 is good with mineral, alkyl benzene and POE oils. RS-44 has been assigned an ASHRAE number of R424A with an A1 order.

A testing program demonstrated that, contrasted with R22, RS-44 had a higher COP, bring down head weights, bring down release temperatures and pressuress, a comparable execution and great oil come back with a wide range of oils including both customary and the new engineered lubricants.The bring down release temperatures experienced with utilizing RS-44 gives critical working advantages.

Trials with RS-44 have demonstrated vitality savings from 10 to 20% contrasted with R22 when RS-44 is retrofitted into a similar framework while accomplishing comparable limit.

RS-45 (R434A)

RS-45 is a potential choice for OEMs and can likewise be utilized to supplant R22 over the scope of utilizations and temperatures including air conditioning and low temperature refrigeration.

RS-45 is a limit coordinate for R22 yet ought not be utilized as a part of frameworks with a hairlike. RS-45 replaces R22 at both higher temperatures and lower temperature applications where a development gadget is available.

RS-45 is a close azeotropic mix with a coast of 1.5°C, 33% that of R407C, which encourages its utilization over a wide temperature go and gives huge advantages on account of overflowed frameworks. RS-45 has a COP which matches R22, comparative release pressure to R22, indistinguishable pressure proportion, is non combustible (ASHRAE security arrangement of A1) and an extensively bring down release temperature than R22 which gives noteworthy working advantages including a much lower danger of oil degradation.

RS-52 (R428A)

RS-52 is like R507 in its execution with high limit at low temperatures. RS-52 has been outlined as a substitution for R502 and the interval ozone exhausting mixes (eg R402A, R403B, R408A and R411B), but on the other hand is a magnificent trade for R22 at low temperatures where the framework is intended to withstand R502 weights.

The high limit of RS-52 at low temperatures is a conspicuous element of this new refrigerant. RS-52 has a temperature skim of under 1°C, and is likewise reasonable for use in overwhelmed frameworks. Know more here
