Gauges on A/C Equipment
With the spot light clearly on refrigerant loss these days
Is it not about time A/C Manufacturers started fitting gauges on all their units as standard ?

Re: Gauges on A/C Equipment
hitatchi and mitsi units now have tranducers on so when u interogate the remote controller you can read pressures without gauges

Re: Gauges on A/C Equipment
yep,i had a trane chiller and it had gauges fittied to it and every time it leaked the capillarys had rubbed through,so fitting gauges isnt always a good idea,transducers are less prone to leakage and are cheaper,but in an ideal world your only gonna fit ur gauges to a system when u suspect problems

Re: Gauges on A/C Equipment
Hi
interesting comments, fixed gauges are another potential leak. Transducers are a good idea, but then every manufacturer will bump the price and have specific connections and techo stuff to connect with either a laptop or similar. Another truck load of fittings or similar.

Re: Gauges on A/C Equipment
Hi Magoo
can see what you both say about gauges is right, would be more than happy with transducers + digital readout
Its just me set in my ways - so used to full rucksack on me back, me dinner one hand and the other free for doors/cat ladders etc that its a nuisance when I have to carry gauges

Re: Gauges on A/C Equipment
It does get annoying, carrying all the gear you need when I do maintenance and I have to drag all my gear across a city I have a single gauge with a quick coupler attached fits in my pocket no need for the manifold and lines, have a comparator on my phone should I need one,

Re: Gauges on A/C Equipment
Or eliminate gauge ports altogether and learn to troubleshoot without gauges.

Re: Gauges on A/C Equipment
To my mind the reason we use gauges is to find out the saturation temperatures.
We can get a good idea of SST and SCT by return bend temps.
Another method is to use a small cardboard disk. Poke a small hole in the center, hold it against the fins in the center of the coil and insert a thermometer through the center hole.
I'm thinking the manufacturers could devise and identify a measuring spot on their particular systems where the temp closely matches saturation (perhaps install a thermometer well?).

Re: Gauges on A/C Equipment
The U bends at the ends of the coils.

Re: Gauges on A/C Equipment
Hi Chiller man.
as per Gary's idea and extend that to make up a transducer[ several ] that connects to say your multimeter, similar to a amp clamp, years ago I had several gauges fitted with schrader connects, packed better in tool bag than a manifold.
