Question about air conditoners

[sammysprinkler]

I am in school right now and my teacher said to ask a technician why is the gauges on the bottom of the unit and not on the top? If anyone could help me with the answer that would be great.

Are you talking about the gauge ports where the hoses
are attached?

None of the units I work on have "guages." I have to attach them.

Im confused.

So you have to bend over and add more wear and tear to your back. Give it 15 years and you'll understand.

I have seen a few units with installed gauges, and they are normally not at the bottom of the unit, but just at or below eye level. Ease of viewing.

Transducers are one of the greatest things thats happend to HVAC that and a good BMS. There is nothing better than sitting down a a computer and figureing out whats wrong with a system.

Most of the newer BMS/EMS systems that I deal with are overrated.

They got too complex too quickly and, now, are either impossible to work on without a laptop and an engineering degree, or they are totally unreliable.

Add to that the fact that the end user, in my case supermarket managers, are totally incapable of reading or operating them, and they create more headaches than they solve.

Now, a nice, user-friendly system that is fairly simple and totally reliable would be great, but they don't make that anymore.

Need to get back to the KISS principles and I will like BMS a WHOLE lot more.

The systems I work on are all operated by building engineers and most of them are the tracer summit, a few johnson controlls, and carrier. But most of the systems are controlled by trained "engineers" whitch makes it very convienient for me. I do agree with you on over complication often resulting in neucent alarms but when the control system is working properly it makes life easy for the service tech. and the people that know how to operate it.

[sammysprinkler]

yeah they are the gauge ports where the hoses
are attached. Sorry I wasn't near my homework and I was trying to remember it off the top of my head.

[amickracing]

More tubing down there than on the top?

[spotts]

so their not ugly.

[mustardman]

Good question but my best guess is so you don't get sprayed by refrigerant in the face if your schraeder sticks a bit.

[Storman]

We put ours at the bottom because the base pan is the most secure place to mount the service valves. Tech getting in there with a wrench will tend to overtightened. So having the service valves mounted to the base gives a stronger mounting platform. Some of the down falls to this is oil in the system will get trapped in the pipes and will get all over the place if you don't know what you are doing. Also the tubing cost of running pressure ports up to the top will get to expensive when you are building 1,000 units at a time.

[koldenhott]

Service valves and tubing at bottom of unit
allows dogs to step over the line sets...
...harder for them to crawl under top mounted
line sets

Actually, the discharge line enters the top of the condenser
(lets gravity work) so the subcooled liquid exits at the bottom...
...therefore, it is natural to exit the condenser cabinet at the
bottom.

And about those dogs, they love to lick the condensate off
the suction line, but while doing so, they chew the control
wire in two which will short out the transformer or blow the
control fuse. That is why it is a good idea to run the control
wire through flex conduit.

Yea, what were we talking about? What a woman!!





I've seen some Dayton's that had the ports about mid ways up on the front! I wuz impressed too (for a Dayton, AKA Grainger).
