veloped by the absorption of 1 lb. of NH3 to changethe concentration from xi = 0.20 to xi = 0.28 (mean concentration x = % (0.20 4- 0.28) = 0.24) is: 887 - 350 X 0.24 - 400 X 0.242 = 780 B.t.u. To lower the temperature of (G — 1) or 9 lb. of weak liquor in the weak liquor cooler, if used, from 140°… … 728 POWER PLANTS AND REFRIGERATION Evaporating Coils. The heat taken into the system by the evaporating coils is He — Hs — qc,in which Hs is the total heat for t0 = 10°, the temperature maintained in evaporating coils, and qcthe heat of the liquid at condenser temperature tc =» 95°.
