NORMAL SYSTEM PERFORMANCE SERVICE STALL HIGH HUMIDITY

Normal System Performance Service Stall High Humidity:

- High humidity conditions affect the system performance by increased heat load on the system. This extra heat load will increase the discharge pressure and the 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 the high humidity has on the Saturn air conditioning system. Use this chart to determine the normal system performance under high humidity conditions.
- As a general rule, normal system operating under high humidity conditions will produce an outlet temperature of at least 20°F below the ambient air temperature.
