settle a discussion for me, at issue is the total r410a refrigerant capacity in
typical minisplit system, ie. mitsubishi, sanyo, fujitsu etc.
I claim a typical 1 ton or smaller system contains about 2 pounds of r410a
It depends on the btu /lb. within the system and how many pounds per minute
you cycle, which depends on the compressor displacement. Different
manufacture's might use different compressors for identical capacity's which
then may require different amounts. If it's a VFD type compressor, then it
may have a receiver, which may hold some excess refrigerant over and above
what a standard non-VFD might.
I'm not sure what you mean by typical - Mitsubishi, Sanyo Fujitsu, or
solues. [Ok - I added the last one.]
