OUTDOOR TEMPERATURE (Degree F)
OUTDOOR TEMPERATURE (Degree F)
COOLING PERFORMANCE CAN BE CHECKED WHEN THE OUTDOOR TEMP IS ABOVE 65 DEG F.
TO CHECK COOLING PERFORMANCE, SELECT THE PROPER INDOOR CFM, ALLOW PRESSURES TO STABILIZE. MEASURE INDOOR WET BULB
TEMPERATURE, OUTDOOR TEMPERATURE, LIQUID 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 LIQUID (4) OR SUCTION (5) PRESSURE IN LEFT COLUMN .
EXAMPLE: (1) OUTDOOR TEMP. 82 F.
(2) INDOOR WET BULB 67 F.
(3) AT INTERSECTION ACTUAL:
(4) LIQUID PRESSURE @ 600 CFM IS 313 PSIG LIQUID PRESSURE SHOULD BE +/- 10 PSI OF CHART
(5) SUCTION PRESSURE @ 600 CFM IS 140 PSIG SUCTION PRESSURE SHOULD BE +/- 3 PSIG OF CHART
