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

Re: superheat/subcool charts.
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.Brian - Newton Abbot, Devon, UK

But I was just wondering what different manufacturers recommend on their non inverter a/c's for superheat subcool.

Forgive my ignorance frank.What is a comparator?
Very similar to the pressure/temp readings from your service gauges.

Re: superheat/subcool charts.
If you ask your refrigerant supplier nicely they should give you one, the one from bitzer is good

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
We've now confirmed DEC are you still up for a meet?
