Unformatted text preview: Experimental Setup and Procedure The experiment uses a Hilton air handler running an R-12 coolant loop. The assembly consists of a centrifugal fan with speed control, steam injector, a pre-heater, a cooler and dehumidifier with condensate drain, a reheater, and the orifice plate used to calculate air speed. Sensors used include # K-type thermocouples and a thermocouple reader (uncertainty +/-1 *C), a handheld humidity and temperature reader (uncertainty +/- 2%), an inclined manometer, a rotameter used to measure refrigerant flow rate, a stopwatch and graduated cylinder. Figure X. Experimental Procedure Setup The experimental setup (Fig. X) shows the air conditioning unit and all critical locations. Air flows from (1) into the centrifugal fan, past steam injection, through the pre-heater, past (2) through the condenser to (3) through the re-heater and (4) and then through the orifice plate. Dry bulb temperature and relative humidity are measured at points 1, 2, 3, 4 using the hand-held...
