Readily available in schedule 80 PVC socket weld. Just use a rubber gasket to mate with a brass flange.

How and why would that be done?

Is there an actual 'someone' behind it or is it all completely machine-generated?

How do you differentiate between real-person posting and bot-posting?

PHM...

What does "BOT" mean in this context ?

Thanks for keeping us current. Please keep it up. Some lesser people just disappear and leave us hanging.

Racing Dan would be The go-to - but from your artist's concept pics I would expect all...

It's in the outdoor unit.

Might be well interesting to do the operating cost / performance comparisons using the AC w/ reheat as versus using a AC as stand-alone and dehumidification as stand-alone systems.

Roll a fatter joint next time through.

Rather than treat the symptoms - you can treat the actual problem by installing a white solar reflective metal roof with high reflectivity and high emissivity qualities.

Just keep the heat out of...

After a while I don't care if I get paid. It's not the money - it's the futile banging my head on the wall. At some point - what's the point?

That's funny - I woke with Toots & The Maytals in my head. Even though I like Winehouse's version of Monkey Man better. Especially live. <g>

How did you know?

How DARE you?

Are the chiller and condenser pumps running?

Is the machine at 33º ?

Or is the recovery unit stopping at 33º ?

If all the answers are yes; no danger.

Even getting into the high 20's F....

I have stuff from 12 years ago.

Cooling only, yes? Not a heat pump?

I'm not familiar with that furnace but I would be very curious about furnace airflow. Because the coil's drain pan will obscure about 5" of furnace discharge...

An electronic air cleaner will remove smoke and provide a much cleaner indoor environment.

Why is the desired space temperature 72º F. in an office environment? Especially at a 40% RH ??? <g>

As I recall; this proposed system is to be two 4 ton units outdoors with multiple heads indoors.

They could be staged so that the system which is higher in the building runs most of the time -...

What sorts of information does a Nest thermostat monitor / collect ?

Take it easy here - you didn't always know everything. <g>

Plus; you know I have to make my quota before they fire me. Work with me a little.

Stop with them negative waves Moriarity. <g>

Five posts now - best to apply for Pro Membership.

And then we can advise you in more technically useful terms.

Charge liquid into the highside until the LP switch makes. Then charge into the lowside in the standard way.

It was my desperate attempt to rely on short attention spans to spare me both the initial shame of having made an error of such magnitude, and also from the quiet disapproval which will no doubt...

Well; let's talk about that pesky application process -

Sometimes people apply for Pro Membership in various deficient ways. Some respond to subsequent assistance and guidance - however; some...

Yes I can.

I'll look into it and let you know.

This isn't 1990 - it's 2024 for goodness sake. Clearly you need a new one.

I was thinking about this as if it were my house and I think would add electric heat to every room and install a thermostat on each one. Baseboard or radiant wall panels. Set the one's in unused...

If the elements are operating along with the condensing unit in heating mode - won't the head pressure be excessive?

"don't have the space" -

If they can't fit more height or width - could they fit in more depth?

A 300 series stainless steel tube and fin coil will require at least 50% greater area to do...

Maybe the resistance heat elements are in the return - or between the blower and the indoor refrigerant coil? FHP puts them right in the outlet neck of the blower assembly.

Can't they just fill the entire space under the duct and between the 2 by 4's with foam?

Right now it's a 5 ton condensing unit on the roof right above the AH with a 2 ton (nominal) compressor in it. 2 ton air handler. Pumps about 22,000 measured BTU's. On a 96º day the house loses...

I have a good deal of success with controlling the indoor blower speed on PSC motors with a speed controller. I was just setting one up this afternoon. I set it for a 35º suction temperature to...

I have several times come across some newish but cheap unknown-name equipment that a customer has bought - which containing obsolete parts; compressors, condenser fan motors, controls.

"Mass before air" - so this is a chiller system doing the cooling?

If so; how is the latent element being addressed?

Floors? Walls? Panels?

How is the dewpoint going to be avoided?

Does anyone within the sound of me typing listen to books, or other things, "on tape". <g>

And if so; what do you recommend?

Someone, who apparently suspects that I lounge around and do...

Over five years since you joined here. First post today. Have you been reading this forum in silence all that time or just happened to think to come back and post today because of the new chillers?...

I'm not missing the point of my question:

You: " . . . . pull a vacuum on the system"

Me: "How are you going to pull an effective vacuum with a leak in the system?"

So; to my logic: "old...

Yes; I do.

I would install actual high efficiency equipment, and operate it at actual high efficiency conditions, for the sensible loading.

And apply independent systems for humidity...

As stated it seems to be completely divorced from any discernible reality.

What is the Manual J result based on specifically? Can you post a copy of it?

How are you going to pull a a vacuum effectively until you repair the refrigerant leak?

The more I think about this the more the premise puzzles me.

How much heat can we possibly be talking about? Maybe 3-4K BTU's max?
How many watts will this CPU arrangement of yours be using at...

Especially after a burnout and using POE oil - I would do it at least once more.

If you put an access tee between the LL drier and the TXV you can measure the pressure drop across the new drier...

Not if you match the air flow CFM to the condensing units tons. Set it at 350-400 per and see it pour out water.



I agree, but AFAIK, the AHRI capacities are slanted toward sensible heat. When...

Good point! <g>

But what about the WHY and the HOW parts ?

Can you post just a close-up showing only the 'twisted tube' part of the system? I promise I won't steal your design. And anyway; I am sure I could build one just from your descriptions and the...

Thanks. I did not know that.

But knowing it doesn't change my answer.

Either the evaporator coil is working properly or it's not: correct cap tube, adequately small SSH, etc. The...

Do your contracted service people take notes of the prior-to and after-completed work? I would like to see the suction pressure and the suction superheat at the compressor recorded at about every...

Heat transfer pastes are stable to Well past 125º F. <g>

How about something like a shrink wrap around the outside of the coils? To force them into firm contact with the pressure vessel?

Oh sorry - right now I think you have a heat exchange problem. But answer the latest questions and maybe that will change my opinion. The thing that I don't think you have is a refrigerant-type...
