The new Zero ODP Drop-in Replacement compatible with all lubricants
HCFC 22 is a controlled substance under the Montreal Protocol and European Regulation and will be phased out on a global basis with all other HCFCs. HCFC 22 is already banned in Europe in most new equipment and is subject to a rapidly tightening cutback schedule. It is, therefore, now time to consider the options for replacing HCFC 22 which will become restricted in availability as these cutbacks come into effect.
RS-44 provides a low cost and easy solution to replacing HCFC 22 by avoiding a costly and technically unsatisfactory retrofit situation. By definition, any replacement for HCFC 22 must have no ozone depleting ability so that, in contrast to replacing CFCs (e.g. R12, R502) where there were 'interim' blends available (largely containing HCFC 22) enabling the existing lubricant in the system to be used, this is not an option when seeking to replace HCFC 22. R424A has a zero Ozone Depletion Potential, a similar performance to HCFC 22 and can be used with all types of lubricants.
Comparison with HCFC 22
Higher Coefficient of Performance
Lower discharge temperature
Zero Ozone Depletion Potential
Non-flammable
Lower discharge pressure
Similar capacity
Compatible with existing oils
No hardware changes needed
The lower head pressure obtained when using R424A provides significant operational benefits, while the higher
Coefficient of Performance reduces energy costs and has a beneficial effect on the Total Equivalent Warming Impact (TEWI)
of the whole system. The significantly lower discharge temperatures and pressures of R424A improve the reliability and
extend the life of the compressor, and reduce the problem of oil decomposition.
ASHRAE Number
RS-44 has been designated an Ashrae number of R424A with a classification of A1, which is low toxicity and non
flammable.
Once again, we are having our Indoor/Outdoor Counter Day on Thursday, July 10th, 10am - 2pm. 14 vendors showing off their power tools, energy efficient equipment, and the most recent technology to benefit the Homeowner and Contractor. Also, a must visit, Energy Star and HFH tents! Please take the time to visit us - Bernie will grill his gourmet hotdogs and serve YaunCo Chili! Fun, Food, Technology, Raffles, Broadway ShowTix!!
Geothermal
Save the date; Tuesday, July 22nd, 8:30am-10am - Bob Karas will get you turned onto Geothermal. Bernie Kistner follows 10:30am-12pm with Pipe Fusion. $20pp at the Liberty YaunCo training room. Register early with peggy@yaunco.com.
Solar Power
July 15th we are hosting ANOTHER solar seminar that was unadvertised - the class was already filled from the waiting list from prior classes. Let me know if you want to be in on the next SOLAR SEMINAR. When I get 15+ then I can get my tech trainer to give a date. peggy@yaunco.com It's a great investment of your time for $40, 8am-4pm!
