Re: Measurement of flow rate
If you know displacement of compressor and discharge (or suction) pressure, you could calculate flow from refrigerant properties (density at certain pressure).
Also, you could use coolpack software for such calculations.

Hi Lioyd,
If you wish the Mass flow rate of your refrigerant you could simply divide your capacity (kw) by your Refrigeration Effect. This might be a little easier than working out your displacement and dividing by the specific volume described earlier by Nike 123. it would depend of course if you are happy with your Mollier charts.

Re: Measurement of flow rate
Moideen, hi actually it should be recorded on a phychometric chart, not as I had written above. I am doing many things at the moment with mollier charts and can confuse even myself at times.
