The best replacement for R-22 Freon is usually R-407c. It has a very low loss in capacity (0 – 5 percent ) relative to R-22 and is less expensive than many other R-22 replacement refrigerants. If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R22.

Is 2 pounds of Freon a lot?

As for how much Freon is in each unit that could be lost due to damage, the general rule of thumb is 2 1/2 pounds of refrigerant per tonne of cooling. The tonnage of an AC unit determines its size and the amount of space it can cool, with larger tonnage units providing greater cooling abilities.

How do you calculate refrigerant quantity?

Divide the quantity of refrigerant that the heat pump moves by the time it takes to move it. If it pumps 3.6 kilogrammes of refrigerant in 10 seconds: 3.6 / 10 = 0.36 kilogrammes per second. Divide the answer to step 1 by the answer to step 2: 51.2 / 0.36 = 142.2 kilojoules per kilogram.
