Question

A water chiller operates with a 4.4C (40 F) evaporator temperature, return water temperature of 10 C (50F) and a 7.2C (45F) supply water temperature. The water flow rate is measured at 682.5 L/min (150 imp. gal./min). what is the cooling capacity?

A. 87 000 W / 300 000Btu/h

B.109 875 W / 375 000 Btu/h

C. 131 850 W / 450 000 Btu/h

D.153 825 W / 525 000 Btuh/h

Answer 1

evapora for To = 7.2°C * 4.4's mm ماده7 IQ = 68205 l/min cooling water in # water out T2 = 110375 kg lo. kw codling capacity = mc(ri-tad 11.3750 4:2 (10-7-2) e k = 133133 W The neqaest ans) 1131850 W
