Table PD-8— 60 Ton — CGAF-C60
Table PD-7— 50 Ton — CGAF-C50
Notes:
1. Data based on 0.0001 fouling factor at sea level.
2. Interpolation between points is permissible.
3. Extrapolation beyond points is not permissible.
4. EER - Energy Efficiency Ratio (Btu/watt-hour). Power inputs include compressors, water temperatures below 40°F.
5. Ratings based on evaporator drop of 10°F
condenser fans and control power
6. Rated in accordance with ARI Standard 550/590-98.
7. Minimum recommended ethylene glycol percentage used for leaving water temperatures below 40°F.
8. Use the following equation to calculate COP values at other than ARI conditions, COP = EER x .2928.
