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 .
(1) OUTDOOR TEMP. 82 F.
(2) INDOOR WET BULB 67 F.
(3) AT INTERSECTION
(4) LIQUID PRESSURE @ 400 CFM IS 295 PSIG
(5) SUCTION PRESSURE @ 1050 CFM IS 141 PSIG
INTERCONNECTING LINES
ACTUAL:
GAS - 3/4" O.D.
LIQUID PRESSURE SHOULD BE +/- 10 PSI OF CHART
LIQUID - 3/8" O.D.
SUCTION PRESSURE SHOULD BE +/- 3 PSIG OF CHART
