TO CHECK COOLING PERFORMANCE, SELECT THE PROPER INDOOR CFM, ALLOW PRESSURES TO STABILIZE. MEASURE INDOOR WET BULB
TEMPERATURE, OUTDOOR TEMPERATURE, DISCHARGE AND SUCTION PRESSURES. ON THE PLOTS LOCATE OUTDOOR TEMPERATURE (1);
LOCATE INDOOR WET BULB (2); FIND INTERSECTION OF OD TEMP. & ID W.B. (3); READ DISCHARGE OR SUCTION PRESSURE IN LEFT
COLUMN (4).
EXAMPLE: (1) OUTDOOR TEMP. 82 F.
(2) INDOOR WET BULB 67 F.
(3) AT INTERSECTION ACTUAL:
(4) DISCHARGE PRESSURE @ 1250 CFM IS 316 PSIG. DISCHARGE PRESSURE SHOULD BE +/- 10 PSI OF CHART
(5) SUCTION PRESSURE @ 1250 CFM IS 142 PSIG. SUCTION PRESSURE SHOULD BE +/- 3 PSIG OF CHART
