Trane 4TTA3030AD000A - Pressure Curves for 4 TTA3060 AD; Cooling with Capillary Tubes; Cooling with Thermal Expansion Valve

PRESSURE CURVES FOR 4TTA3060AD
GAF2A0A60
Cooling with Thermal Expansion Valve
LIQUID PRESSURE (PSIG)
OUTDOOR TEMPERATURE (Degree F)
SUCTION PRESSURE (PSIG)
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. 95 F.
(2) INDOOR WET BULB 63 F.
(3) AT INTERSECTION ACTUAL:
(4) LIQUID PRESSURE @ 1750 CFM IS 134 PSIG LIQUID PRESSURE SHOULD BE +/- 10 PSI OF CHART
(5) SUCTION PRESSURE @ 1750 CFM IS 404 PSIG
SUCTION PRESSURE SHOULD BE +/- 3 PSIG OF CHART
INTERCONNECTING LINES
GAS - 7/8" O.D.
LIQUID - 3/8" O.D.
