Hello all.
Does anyone know where you can obtain superheat/subcool charts for some of the more popular brands of split systems?

Hello all.

Would a comparator not be of any help?
I don't know whether the 'modern' splits are provided with them; not like the old Carriers etc.
They assume, I think, that you have measured the pipework lengths and adjusted the charge accordingly.
Forgive my ignorance frank.What is a comparator?Quote:

(Definitely inverters.)
But I was just wondering what different manufacturers recommend on their non inverter a/c's for superheat subcool.
It resembles a slide rule and gives the saturated vapour temperatures against gauge pressures for different refrigerants.Quote:

Very similar to the pressure/temp readings from your service gauges.
Normally I use pressure temp chart.Quote:

Definetely not small enought to fit into your pocket:)
How many refrigerants does it cater for?
If you ask your refrigerant supplier nicely they should give you one, the one from bitzer is good
Normally 4 or 5 different gases. Really handy to have in the tool box :)Quote:

Hi Frank,
Danfoss used to make them.
Do they still do?
Chemi:)
Hi Chemi
Most of the ones we now use are provided by the refrigerant suppliers. Even picked up the latest R410a one at the NEC :D
We've now confirmed DEC are you still up for a meet? :)
A-Gas in Bristol do a good one: www.agas.com
