An evaporator inlet accumulator?

[Uni]

Has anyone seen a kind of muffler/accumulator just after the capillary and before the evaporator inlet?
What's the role of this device then?

Thanks for reading

Give us a clue, what is it on?

I 've seen similar things on milk vats, a Berkit liquid re-gen assembly, after TX vav. Cannot say Ive seen one fed with a capilary

Guys,

That one is on a 2.2kw heatpump.

It has two little mufflers at each evaporator inlet. The mufflers are fed by the capillaries and their outlets lead to the evap inlets. They're exactly like the discharge line muffler.

I wonder if they're used for regulating the refrigerant flowing into the evap.

Probably just filters unless they are the non-return valves, depends how big they are.

Heat pump = reversing flow.

Thanks, Brian

It's the like, and approx that size, too. Not longer than 2.5", less than 1" diameter.

It's makes me curious about its role in the system.

unless they are the non-return valves

Check-valve is normally regconized with a loop of another cappillary for bypassing which is not there.
