Wait !
Your profile says you're a HVACR engineer 🤔

It called a hit & run 🙄

 

[VTP99]

That's what you do when you turned the valve stem all the way out but still need more capacity 😃

 

[VTP99]

Why would the inlet pressure be reduced ?
If that was the case every walk-in cooler / freezer with multiple evaporators on the same liquid line would have capacity issues.

 

[VTP99]

I see what you're saying but that would be a interesting check valve.

Not if it's acting as a metering device.

Ehsx seems to be saying he doesn't think that's the case.

Personally, I believe that's what the crimp is - an orifice.

We don't know the I.D. of what appears to be a 3/16" line also they added a loop I'll assume to acquire a certain length.
That said, the line itself could be the metering device.

It would have been doubtful anyone would install a bypass like this yet here we are.
So suffice to say anything is possible 😉

Hi all,
Thank you very much for your replies.
Yeah, I'm from Asia country, so time zone might differ.
I've got the answer:
That bypass captube is to provide more capacity. Why not using higher capacity TXV: Lower capacity TXV provides more precise control. Those short capacity would be compensated with the bypass captube.

I'll revert back to the OP ☝🏻

 

[VTP99]

I think you just like to argue

The pot calling the kettle black 😆

Wait !
Is there a right vs wrong 🙄
What's your conclusion so we know what's right vs wrong 🤔

 

[VTP99]

Then there is the sanitary engineer ( janitor ) 😃
