Hey everyone!

Are there any recommentations about variable speed drive pumps in condenser or evaporater circle?

Once we installt a NH3 chillerpackage with an vsd evaporater pump. The speed regulation depands on the temperature difference between evaporater glycol in- and outlet. This system runs perfect without any troubles and is high efficency espacially in part loud times.

Has anyone experiences with vsd pumps and would it also be possible in dx systems?

Have a good time!
