R22 407c conversion

The objective of this study is to present test results and to develop a dimensionless correlation on the basis of experimental data to predict the mass flow rate of R22 and its alternative refrigerant R407c through an electronic expansion valve (EEV). The mass flow rate was measured at a series of condensing temperatures, evaporating temperatures and degrees of subcooling at the EEV inlet with ...

The perfect refrigerant reading depends on several factors, like atmospheric pressure and temperature. I like to see an average range of 58-85 PSI on the low side and 120-300 PSI on the high side. These indicate that the unit is running okay and should be cooling properly. TL;DR: R22 is almost phased out and even banned.Performance. Refrigerant.

Daikin R-407H is a new generation replacement for R-404A type systems and the best in class retrofit for R-22. It is built on the proven chemistry of R-32, R-125 and R134a to provide a pressure and temperature match to R-404A and R-507 with a lower GWP, equivalent capacity and better efficiency. It is perfect for refrigeration applications such ...Compressor capacity will be comparable to R-22 in medium temperature applications. R-407C should be used only in systems that currently use R-22. It should not be mixed with R-22 or any other refrigerant. The capacity of the existing R-22 thermal expansion valve (TEV) will be approximately the same when using. R-407C.Best Capacity and Eficiency Match to R-22 in A/C Applications. Genetron® 407C is a non-ozone-depleting HFC-based refrigerant for replacement of HCFC-22 in residential and light commercial air conditioning systems. It has a capacity comparable to HCFC-22, making it easier to use in existing equipment designs.

In the conversion equations below, H (ref) and S (ref) are the saturated liquid enthalpy and entropy at -40 °C. For Freon™ 407C, H (ref) = 146.6 kJ/kg and S (ref) =Aug 27, 2023 · Conclusion. The comparison of R22, R410A, and R407C refrigerants underscores the industry’s commitment to balancing cooling performance with environmental responsibility. While R22 has been phased out due to its environmental impact, R410A and R407C represent energy-efficient and lower-GWP alternatives that …R-438A is approved for R-22 retrofit on medium and low temperature parallel rack applications using Copeland Discus compressors.
