Example 2: The following data apply to an air-conditioning system RSH=11.6 kW RLH=11.6 Kw In side condition 25°C & RH=50% & outside condition 35°C DBT & 27.8°C WBT Return air from the room is mixed with the outside air before entering the cooling coil a ratio 4:1 Return air from the room is mixed with the air leaving the cooling coil at a ratio 1:4, cooling coil by pass factor =0.1. The air may be reheated if necessary before suppling the condition, assume tdp=10°C. find 1- Supply air condition to the room 2- Refrigeration load (Colling coil load) 3- Total refrigeration capacity d- The quantity of fresh air supplied
