We assume that there is no heat dissipating instrument in the room
Total cooling load of the room is defined from the given below equation
=
+
+

where
= 10*100 W =1 KW
= 40*360 KJ/h= 4 KW
=15000KJ/h= 4.17 KW
= 1+4+4.17=9.17 KW
the number of air conditioner unit is =
=1.83
which is approximately 2 units
