NOTES:
1. The heat rejection capacity is the capacity of the fluid cooler. The fluid cooler can mitigate a major proportion of heat load.
2. Air flow is set at 2500 CFM for the 3 ton / 3500 CFM for the 5 ton.
3. Approach Temperature is defined as the temperature difference between leaving water temparature and entering air temperature of the fluid cooler.
4. The entering load water temperature of the system will drop if the fluid cooler can reject more than the system heat-of-rejection capacity.
