In a CAV air-conditioning system in a building, 150 cfm of outdoor air is mixed with 1350 cfm of zone air at 75 F and then enters the cooling coil. The air leaves the coil at 50 F and 95% RH. he sensible load for the zone is 2.5 tons and the zone sensible heat ratio is 0.8. Determine (in tons) the total zone load, reheat energy, ventilation load, and coil load for the following two sets of ambient conditions. a. 85 F db and 60 F wb. b. 85 F db and 75 F wb. Draw some conclusions from your results.
