Consider the system shown below:

Given that on summer days, only the cooling coil of the air conditioning system

is operating, and the following conditions exist:

RA $,$t$=24\backslash$deg C DB

$1,2,3,$t$=12\mathrm{.}8\backslash$deg CDB$,\backslash$phi $=100\%$

OA t$=35\backslash$deg CDB$,$t$^(*)=25\mathrm{.}6\backslash$deg CWB

SA $,$t$=13\backslash$deg C DB

$10\%$ by mass outside air is required for ventilation

Space sensible heat gain, Q$\_($s$)^()=37\mathrm{.}8$kW

Space moisture gain, m$\_($s$)^()=7($g$)/($s$)$

Determine

am$\_($SA$)^()$
