Heat Pump Gauge Use.

I know what you are talking about now RoBoTeq, you've pretty much described what me and everybody else I've worked with and went to school with calls an accumulator. In fact the the description you gave reads almost like the description for an accumulator for a heat pump out of my old textbook. It never called it a charge compensator.

Not even close. Completely different device.

Guess I got myself mixed up.But at least I learned something...

I stand corrected gentlemen

[clifpaul]

My apoligies for the lousy picture posting btw.

That's a better pic than anything I've found so far.

[clifpaul]

Thanks. I learned something myself since I didn't know there was a difference.

Here is a pretty good pic showing the difference between a compensator and an accumulator.


Don't know why pic did not show but here is the link. http://www.cwis.net/~mallie/CompensatorSS.bmp

Good conversation guys. Learned a couple things.

Last used in the 90's. Back when Robo had big hair and tall shoes!

LOL! What makes you think RoBo doesn't still have big hair? Well, maybe not as big, but it still covers all of my head. And the only tall shoes I ever wore were boots.

As for charge compensators, they are still out there.

Don't forget its still just a refrigeration system.

Exactly !!

It makes my skin crawl, when someone claims that you can't "properly" charge a heat pump system in the winter....

If you can't charge a heat pump in the winter, how do you charge a wine display in a liquor store at any point in the year?

That's the difference between guys with "knowledge" and guys with "understanding"...

[John Markl]

X@. I've seen accumulators, but I've never seen or heard of a charge compensator til now.

Paul, next time you look at an old Rheem heat pump indoor coil, you might notice a "chunk of copper" about 1-3/8 inches in diameter along the side of the coil. That is one type of compensator. Newer units have them in the outside unit. Often on Rheems, they are blue in color.

Like this John? Its on the indoor coil of the old Rheem heat pump at my house.

Ok. I was wondering what that was. And now I know. I couldn't find any info on it in the service or the install manual for the unit. I knew it couldn't be the txv because you have to pull the coil out to get to it.

That was one of Rheem's dumber ideas for charge compensation. It took so long for the refrigerant to collect in the compensator that the system would go out on high head.

I believe that was the RCQB model.

I believe that was the RCQB model.

You would be correct sir

a great read, picked up some good info, this is very usefull >(Hot gas, 110F + OAT = Discharge temp)....can I ask what does SC&SH stand for?

That would be the superheat and subcooling temps
