> L L per ton of refrigeration, 20 lbs. of water = -2v4"gallons* This is a minImran amount of water wasted per ton of refrigeration. A greater amount of water wasted is the usual practice. of water is circulated per ton of refrigdration per mi for the simple reason that a maximum rise of 5° to 10° is the usual practice, but due to the fact that the only water wasted is by evaporation, approximately 85° of water as compared to the waste water system. Difference of opinion will be expressed by some manufacturers and salesmen of cooling tower and evaporative condenser recireulating systems with exaggerated claims up to as high as 95% to 98% of the water save. These claims are ridiculous, and the facts can only be proven by placing abater meter on the system. Explanation of what is meant by Continuous Drain of a recirculating system. All the minerals that were originally in the water remain after evaporation. To avoid excessive concentration of the minerals, dirt and solids from accumulating in the recirculating system and in the refrigeration condensers, it is necessary to maintain a Continuous waste drain off or wbleedB of the water recirculated in addition to that which is wasted L_ When a cooling tower or evaporative condenser is used and the water is recovered and recirculated, a much greater $antity drift and continuous drain, ikhe recirculating system will save Bg V ^ ,N ' by evapor vf ?
