The 422d freon is the colder one. R22 is believed to cause a combustion hazard during a pressurized leak test with air.
The terms in row 22 are 22Cr where r = 0, 1, 2, ..., 22. 22Cr = 22!/[r!*(22-r)!] where r! = r*(r-1)*...*3*2*1 and 0! = 1
22/7*D (or) 22/7*R*R
R-22 has HCFC (hydrocloroflorocarbons) R-410A has HFC (hydroflorocarbons)
"Freon" is DuPont's trademark for its CFC refrigerant products. R-22 is one of those refrigerants, so R-22 and Freon-22 are the same refrigerant.

the two factors r they are colder then the others
yes
R-22 refrigerant is depleting ozone. It is because it is a CFC.
R-22 is still available, because of this there is no need for a drop in. So there is none.
R-22 is a colorless gas that is used as a propellant and refrigerant. The technical name for this gas is chlorodifluoromethane.

It is 22 + R
