Expansion noise - capillary tube into evaporator

[desA]

Be sure to change the drier orientation, too.

I've been mulling this one over for some time, having installed this orientation in another test heat-pump. I have to say that it gave me some very, very odd results, that were not overly simple to explain away, other than the vertical drier orientation. I am now not too convinced of its effectiveness, I have to say. Sporlan advocate this, but I've not seen it in other literature (probably is there, & I've missed it).

Care has to be taken in some instances, I expect, with the drier position relative to the condenser discharge & type. It can present issues within the condenser itself in terms of liquid-clearing.

For a vertical heat-pump, the clearing issue should not affect the condenser as it already has to push the liquid upwards a fair amount.

I remember Chef's concern regarding the possibility of this filter-drier accumulating too much refrigerant & that this could create a problem under critical charge conditions. Perhaps we could discuss this further?
