HEATING VENTILATING AIR CONDITIONING GUIDE 1941 Standard9 in the formulation of its ratings and has compiled a tentative standard of heating effect allowances for various enclosure heights to be included in the ratings by its members.

HEATING VENTILATINC AIR CONDITIONING GUIDE 1941 heating systems consists of a motor-driven centrifugal pump with receiver and automatic float control.

HEATINC VENTILATING AIR CONDITIONING CUIDE 1941 Determine Cooling Load on Air Washer Heat removed, outside air = 470 (ho -- hi) -- 470 (38.46 -- 24.4) = 6600 Btu per min Heat removed, return air => 1010 (ft, -- fti) = 1010 (31.51 -- 24.4) = 7180 Btu per min Total Refrigerating effect = 13,780 -s- 200 = 68.9 tons. 13,780 Btu per min Determine Reheating Required H = Wcp (t, - t,) = 1480 X 0.24 (68 - 57) = 3910 Btu per minute = 234,600 Btu per hour.

HEATING VENTILATING AIR CONDITIONING CUIDE 1942 Table 2.

HEATINC VENTILATING AIR CONDITIONING CUJDE 1942 tion, together with the reduced heat losses up the chimney by reason of decreased gas velocity, results in fuel economy, with consequent lower costs of plant operation.

HEATINC VENTILATING AIR CONDITIONING GUIDE 1942 gas passages must not be so small as to cause excessive resistance to the flow of gases where natural draft is employed.

HEATING VENTILATING AIR CONDITIONING CUIDE 1942 by precooling the brine in the solution cooler to a predetermined tem perature, which is usually below that of the air, by city, well or chilled water.
