mystery connection ICP Heat Pump? See Pictures please.

[mdman]

Can anybody tell me what this mystery connection is on this ICP Heat Pump?

TIA,

I think that it's purpose is to equlize pressures in the off cycle so the compressor doesn't have to hard start.


I'm just guessing.

[mdman]

anybody know definitively what this is? It's killing me.

I've never seen anything like that, maybe it is supposed to be a bypass and they screwed up at the factory and connected it to the wrong place

[mark beiser]

It looks like it has a check valve in the fitting going into the vapor line.

I have no idea what that could be for...

[hvacprodmgr]

OK, I hope I am saying this right (but I probably am not)
Remember this is a heat pump, which means in the heating mode, this is our TXV, then feeding the distributor. So it kind of acts like a desuperheating TXV and just redistributes the flow to keep pressures equalized.

Yes, you are correct. All of the ICP TXV's are bi-flow with a built in check.

It does appear that it may have been replaced. What model and serial is this thing ?

Hope this helps..........

Now I'm going to have to go buy one of these, just to cut it open.

What model is it?

[mdman]

Yeah, it's bugging the crap out of me too. Nothing from the group yet but guesses.

Could not see your pics on the post.
I would need a M# S#.
ICP had a 14 seer unit with an equalization tube for the heating cycle.
It did not work well. You need to contact ICP if you are a contractor for more info. The unit was produced for one year only.
