View Full Version : water cooled condenser question.
04-30-2005, 09:23 AM
I have Trane water cooled packaged units. I wanted to know if there was a chart of what my high and low side pressures should be in relation to my inlet and outlet condenser water temperature. My boss is telling me there is such a chart,I dont think there is. I know theres PT charts for refrigerants. There is also a quick formula for finding out what your high and low pressures should be utilizing the entering water temperature.Any help would be appreciated. Thanks.

think of the water as air. condenser water should be around 80 degrees supply and should maintain a 110 degree condensing temp, which is around 210 lbs. also head pressures above 225 degrees tend to foul the condenser faster. suction pressure will depend on evaporator being dx or chill water, if its dx and i am assuming this then suction pressure will be about the same as a standard dx system. subcooling should be around 10 degrees if theres less add freon if theres more remove some. superheat should be anywhere from 10 to 20 degrees and im assuming you have a txv.
