Step 1: Establish design conditions
 Indoor air temperature 25°C DB, 18°C WB; outdoor air temperature 33°C DB.
 Determine peak load of each room and system peak load. As shown in Table 1-6.1, the system peak load is 34kW.

 Indoor unit type for all rooms: Medium Static Pressure Duct (T2).
Step 2: Select indoor units
 In this example, a safety factor is not used (i.e. the safety factor is 1).
 Select indoor unit models using the medium static pressure duct cooling capacity table. Each indoor unit's corrected
capacity needs to be greater than or equal to the peak load of the relevant room. The selected indoor units are shown
in Table 1-6.3.
