fast charging on low side

[Nrmika]

Hi I am just curious where you guys feel is the best place to put the orificed flare fitting that flashes the refrigerant from a liquid to a vapour when you are using a zeotrope nd want to charge by vapour as apposed to feathering in liquid on the low side?

On the bottle.

I still don't know if that little gizmo is any faster than just making it flash through the manifold. I had one until I did something stupid and used it to purge one of those seal-rite hoses in a pinch and sent the orifice flying. I hate those hoses.

I suppose putting it on the manifold where the low side hose connects would also be a great spot.

[Nrmika]

Yeah that's what I thought too. I didn't know the orifice came out so I will try to avoid turning it into a projectile weapon....

I know they are not expensive, but save the money. You accomplish the same thing by just opening you manifold slightly.

[Nrmika]

Already got it so I might as well use it and try to compare using it with not. I want to see which is faster.

Using your gauges is faster. I had an imperial kwik-charge that I use to use but found the manifold was just easier.

I put a sight glass on the center port. Allows you to see the gas/liquid and adjust valve to charge direct from cylinder.

Is this still effective with zeotropes? With two different evap points couldn't you end up with to much of one and not enough of the other refrigerant?

[timjimbob]

That's why you don't charge as a gas.

After it leaves the jug as a liquid it doesnt really matter

[Nrmika]

I guess so any difference in volume of refrigerant entering thy system would be fairly small

[ar_hvac_man]

I reckon the only fractionization would be in the hose downstream of where your flashing. Very slight

[Nrmika]

Good point hvac man
