Cooling Air temperature Vs. Chilled Water Temperature
Cooling Air temperature Vs. Chilled Water Temperature
(OP)
In the project I am working on, the air needs to be cooled from 140 F to 50 Deg. F to serve the specific machine. The heat transfer is through an air-to-water cooling coil. The chilled water is available from a central chiller system and the supply temperature is 44 Deg. F. My question is: Is it feasible to cool the air to 50 Deg. F by only 44 deg. F chilled water? What is the minimum temperature difference between cold air leaving temperature and chilled water supply temperature, for the best performance of the coil?
Thanks in advance for any feedback.

With a 44 deg.F water temperature, it would be possible to achive approximatly 45 deg.F leaving air temperature, although the coil block would be about 9 rows deep!.
As billyg suggests, talk to a good coil manufacturer.
