hitting the crack pipe lol

To add more water and bleed out some glycol, take a water container with a fitting to the top, and connect a hose to the bleeder valve. Make sure there's no air in there. Have someone open the bottom until it starts refusing to drain out, and open the bleeder valve. That should drain water from the container at the top into the system while glycol/water mix comes out the bottom. Shut it off when you get close to emptying the container, then shut off downstairs No air entry into the system.

It’s very cool you seem to be able to work on everything. I hope to be at your level in my career

Been a programmer working with Facility Explorer for 12 years. It’s ruined me lol…anytime I walk into a building conditioned with more than a small split system I get curious and start looking for clues as to what control system they have. Most impressive is that a church actually spent money on controls lol…

having that ole type compression tank, you should not have any other auto vents on that system, except that they can be there for the first fill, refill, then valved off. You need to figure your air separation at the compression tank, and at that primary air separator / swirl tank, Dan Holeran, Pumping Away, tank isn't piped or pumped correctly

@HVACRSurvival

Жыл бұрын

Glycol's a lot like antifreeze in your car. Systems that have water coils whether it be for chillers or boilers can run glycol in it.

Do they have two heat emitters requiring variable fluid temps? Do not get why they have the mixing valves if the boilers can modulate. Are they intending for the cooling water temp control? Hard to judge a system at arms length

@HVACRSurvival

Жыл бұрын

I think the boilers are newer than the valves, I believe there are piping issues then add that to being over controlled

Why not leave the glycol in year round? Efficiency concerns with heat transfer?. Sounds like a waste of money to do this twice a year. Ahh… just heard you bring up efficiency in the video. What is the efficiency loss versus pure water.

@HVACRSurvival

Жыл бұрын

That's not what I was trying to explain. They "used" to only use water. Then drained the chiller every year. Now, it will NOT BE DRAINED because it has the glycol. I forget the eff loss, but the higher you go the more you lose.

I'm really confused on why they go form water to glycol for heat, and glycol to water for cooling? Keep it a constant glycol. There is a parameter in configuration to change the carrier to a glycol chiller. Maybe im missing something

@HVACRSurvival

Жыл бұрын

Yeah you're missing that they've always been water in the past, never had glycol in the past, ever, they wanted glycol now so we drained the water out we put glycol in we're not taking the glycol back out.

What is the acceptable over limit of concentration like if you have -5degrees target temp?

@HVACRSurvival

Жыл бұрын

You can go over protect the waters freeze protection and it will still transfer heat to or from the air coil but you start losing efficiency, I'm not sure without doing more research exactly how much you start losing.
