Here we will learn the R422D Pressure Temperature Chart. R422D refrigerant is a low-toxic, non-ozone-depleting hydrofluorocarbon (HFC) used as a replacement of R22. It supported conventional and new lubricants, like mineral alkylbenzene (AB) and Polyester oils, mostly system retrofitting to R422D not needing to change the lubricant. This multiple-operation refrigerant operates in existing medium and low-temperature direct expansion refrigeration uses, such as commercial markets. It is also good for static DX air conditioning systems, like DX water chillers.

R422D Features and Benefits
- There are many advantages of R422D.
- It is less cost retrofits as compared to R404A, R507, and R407C.
- it has a thirty percent lower GWP as compared to R-404A and R-507.
- About 8 percent improved cooling featues and up to 14 percent efficiency than R22 for low temperature. it has low cooling about five percent capacity and efficiency than R22 for medium temperature conditions, with 6 centigrade cooling.
- ASHRAE safety classification A1. Its maintenance is easy when the retrofit is finished, the system can be topped off with MO29.
What is 422D refrigerant used for?
The 422D is a non-ozone-depleting HFC-based refrigerant used as a replacement of HCFC22 for low and medium temperatue systems. Genertron 22D is a mixture refrigerant best for expansion evaporators, it is not used in systems that uses employ flooded evaporators.
Can you replace R22 with 422D?
422D is replacement of R22 in AC system. In many uses receiver R22 replaces critical seals, recharges the system with 422D, and performs normal checks.
What is the difference between R22 and R422D?
The densities of liquids are the same for R22 and R422D, with the vapor density being higher for R422D thatn for R22. Both liquid heat capacity and vapor heat capacity values is 15 to 25% higher for R422D and the difference increases with pressure increases.
Is R422D banned?
There is no restriction on the use of these systems, other thatn the prohibition on the use of virgin refrigerant after 1 January 2020.
Can you mix R22 and R422D?
Do not mix refrigerants in a refrigeration system or recovery cylinder. The refrigerant mixing makes a non-reclaimable mixture that increases the cost of disposal fees.
Is R422D compatible with mineral oil?
The hydrocarbon component in R422D promotes oil return in a system having mineral oil. Though HFC refrigerants do not mix with oils, the hydrocarbon component thins oils and keeps moving about loop.
What is the difference between R422D and MO99?
R22D has a capacity eight percent lower than R22 like MO99. The mass flow rate of R422D is 30 percent higher thatn R22, an extra 20 percent higher than MO99.Expansion devices undersized and changed with using R-422D
Advantages R422D
- It is an approved R22 replacement drop-in refrigerant through carrier commercial.
- It operates in the R22 system without needing an oil change to costly synthetic oil.
- It has the advantage of low energy use.
- its capacity is about R22.
- it has low discharge pressure and temperature while reducing compressor workload.
- R422d refrigerant can be mixed with R22 without system operation issues.
- It has to work in all types of systems with all types of compressors for ten years.
- R422D refrigerant is made in Texas, the UK, and China.
