This article refers to troubleshooting refrigerant charge on 410a and R22 residential air conditioning systems. Although many of the principles will carry over to other types of refrigerants and drop-ins.

R-22 air conditioners use mineral oil and R-410A systems use synthetic oil. The synthetic oil is generally more soluble with R-410A than mineral oil is with R-22. This means the R-410A system operates more efficiently reducing wear and tear on the compressor.If it is using a piston or other fixed metering device, you must refer to the manufacturer's superheat requirements or a superheat chart like the one below. If it is a TXV-type metering device, the TXV will generally attempt to maintain between a 5 – 15 ° superheat on the suction line exiting the evaporator coil (10 ° +/- 5 ° ).Flowcheck Pistons,Flowcheck Pistons. Rheem Manufacturing ranks as the global leader in the manufacture of high-quality, sustainable, and innovative water heaters, tankless water heaters, air conditioners, furnaces, pool heaters, and HVAC systems for residential and commercial applications, and is a full member of AHRI, the Air-Conditioning, Heating, & Refrigeration Institute. R-410A. It is believed that the larger discrepancies in the energy balance for R-407C and R-410A are related to uncertainties of the refrigerant properties. The cooling and heating capacities reported in this paper were from the air side measurement data. Refrigerant temperatures were recorded using type T (copper-constantan)Freon™ 410A (R-410A), wt% 50 50 — Because Freon™ 407C and Freon™ 410A are mixtures of HFCs, they have zero ODP. Table 1 lists the chemical names and formulae of the components that make up Freon™ 407C and Freon™ 410A. Table 1. Components of Freon™ 407C: HFC-32/HFC-125/HFC-134a and Freon™ 410A: HFC-32/HFC-125R-410A. Like R407C, R-410A is a zeotropic mixture, and it's made by combining R-32 and R-125. In the case of R-410A, however, this difference between their two boiling points is fairly minimal, and the refrigerant is considered near-azeotropic. Azeotropes are mixtures with a constant boiling point, the proportions of which can't be changed ...*Piston size needed for system combination may not be pre-installed. See Table 1 for pre-installed size. **Necessary piston size varies for this tonnage. See Table 3. Table 3. R410a piston sizes for 2.5T outdoor capacity system.

I built one and it was fast, it was 4.057x 3.975. The W30 400 in 66 and 67 had 7 inch rods and all of the piston were 1.61 ch. They had forged internals a big cam, and .942 lifters, like a mushroom lifter. They were good for 7000 plus,amazing for the time.

The stickers applied to the TXV kits and orifice are color-coded (pink for R-410a and green for R-22) to assist with proper selection of the kit. DANGER: Be sure to release the nitrogen holding charge. Pressure may also be released through the service port if one is present. If no holding charge Example R-22 3 ton orifice is about .61 410A is .58 .. You need to drop about .03 to.04 . Your head pressure will be higher sub cooling wll come inot range and you will get cooling. Need to know tonnage and make of equipment to size new orifice. ... Take front off and check number on coil and I can cross piston number, Customer:The orifice will need to be changed. The question is whether the evaporator is rated for the 410 pressures. In the early days the R22 evaporators could not contain R410, but after 410 came out mfg’s started making heavier coils that could support 410 but R22 was cheaper and we had experience with it so we continued using it even though it was being phased out.
