i service a SS water chiller and all summer long they have be saying that the water temps have been a bit higher than normal. i figured it was due to the extreme heat in the midwest
today i looked things over and noticed that there is no control for the hot gas solinoid it just on all the time. there is a bypass regulator on this machine. so its not so bad but i thought thats kind of a waste of btu's
getting to my question, can i control this solinoid with a pressure switch? or was it designed to bleed HG into the evap for a reason...
when bypass is not needed the hot gas in the line may condense and then i have a water hammer effect on the line...?
