Refrigerant charge

[danod]

would like to know how much liquid r134 a receiver would hold that is 24inches od by 19feet long at 80% capacity, need to know in lbs or kilograms, thanks in advance.

Inside radius2*Π*h*80%

24X2.54=60 cm 19X30=270 cm
60/2=30
30X30X3.14=2826 cm2
2826X270 = 763020 cm3 =763.020 litter
763.020 X%80 = 610 litter

19 feet long i hope you aint got a 12 kilo bottle cause it aint going to do much? 19 inches may be?

[danod]

this receiver is 24 inches outside diameter by 19 feet long, 2 tags stating charge. 1 says 3500lbs and the other tag says 3500kg

Dear danod
could write how you calculate that .

Have you tried contacting the manufacturer?

The vessel will not hold 3500 lbs of R134 Dead Empty to 100% full....At 100 Deg Liquid Temp and a "true" 18" OD it would hold less than 2200 lbs at 0.375" wall thickness....if the length of it is a piece of 18" Std Weight Pipe that would be its thickness.

If this is a through type receiver with big condensers you will need to know the sealing charge for the receiver which could be almost anything but should be considerably less than 300 lbs. If you have head pressure control and little variation in terms of low side volume and content (ie pump down requirement) then a big air cooled condenser with head pressure controls as regulators and check valves defines much of the remaining charge requirement.

But considering for a moment that tag: I would defer to the manufacturer, or a much more involved analysis of the system's charge requirement...But if you are thinking that receiver is going to hold the low side charge on a nominal "complete pump down" I would be concerned about either number.

Scratch that last: Fumble fingered the original data input.

The 24" Diameter, 19-foot overall length vessel, at dead empty to 85% of max content, will take 3370 lbs of 100 deg F liquid...
But the rest of the post above sustains, whether or not it suits your circuit is a considerably more involved topic. And 3500 Kg is a long way from the max swing for this receiver.
