It is generally accepted that water cooled chillers consume less energy than air cooled units for the same capacity. But is that all, that need to be considered while selecting a system?
Air is (still) free, it is not charged! But water? Even if one is willing to pay for it, can the required quantity be continuously assured? That too in summer, when air conditioning is essentially required? Water of the same quality through out the year? Are clients willing to invest on water treatment plants? Can they be easily maintained or, will they ever be maintained at all? What happens if the parameters are not maintained? Does any one, really understand the effect of fouling factor etc in the long run, as a result of the above factors?
I WISH OUR COMMUNITY CONSIDERS ALL THESE WHILE RECOMMENDING AGAINST OR A FOR ANY SYSTEM!
