Sensible heat factor for indoor units

[Mech engineer]

Dear all,
If i have an indoor unit with capacity of 5 kW. And sensible capacity of 3 kW.
But the room capacity it served is 5 kW total,4.5 kW sensible capacity.
Can the unit achieve the sensible capacity of the room?

No, indoor unit must satisfy the sensible heat load first, then check the latent load later.

The previous poster is probably right, BUT if conditions are dry enough to avoid latent cooling you will get more than 3kW sensible cooling, probably not 4.5 kW though.

Do your diligence and check the actual performance at your design conditions by having the manufacturer do an actual selection rather than just looking at catalog values.
Base your selection on both internal conditions (dry bulb temperature and dewpoint/RH) and outdoor conditions (if this is a DX unit as I suspect).
