Normal System Performance - Service Stall High Humidity

Normal System Performance Service Stall High Humidity:

^ High humidity conditions affect system performance by increased heat load on system. This extra heat load will increase discharge pressure and outlet temperature. High humidity is defined as a relative humidity higher than 70 percent at 21°C (70°F), 60 percent at 27°C (80°F), 50 percent at 32°C (90°F), and 40 percent at 38°C (100°F).
^ This chart illustrates the effect high humidity has on the Saturn air conditioning system. Use this chart to determine normal system performance under high humidity conditions.
^ As a general rule normal systems operating under high humidity conditions will produce an outlet temperature of at least 20°F below ambient air temperature.
