Figure 8. Space thermal profile with a conventional System.

 

    Knowing the amount of time to cool the space and the unit(s) FLA, the kW/hr for the conventional system on design day was 48.60.  The supply fan esp. was assumed at 1.5” w.c. to account for the 4-way diffuser. The energy analysis is shown in Table 2.
