Latent load

latent load

[′lāt·ənt ‚lōd]
(mechanical engineering)
Cooling required to remove unwanted moisture from an air-conditioned space.

Latent load

Cooling load that results when moisture in the air changes from a vapor to a liquid through condensation. A latent load puts additional demand on cooling systems in hot, humid climates.

We have to consider different inputs because of humidity; if you put people in the room the latent load will be much higher and the savings are much less.
On the other hand, when the outdoor air humidity ratio is much lower than the desired return air humidity ratio, the cooling coil operates at completely dry conditions and does not handle any latent load.
An energy-efficient home must also manage a different latent load profile compared to conventional construction because of reduced natural infiltration, added ASHRAE Standard 62.
That is because smaller heating and cooling units can be used if they don't have to perform the double duty of removing the latent load.
Since radiant cooling alone cannot remove latent load and pollutants, such as volatile organic compounds, it should be supplemented with ventilation.
Note that for fan systems, during occupied hours, Q is the coil load, including the sensible and latent load of conditioning the ventilation air with credit for any air-side economizer capacity at prevailing return-air and outdoor-air conditions.
This motivates the introduction of the hybrid air conditioner where the latent load is handled by the desiccant wheel and the sensible load is handled by the vapor compression cycle (VCC).
The DOAS is responsible for bringing outside air into the building and also takes care of the latent load from the outside air.
Under some conditions, either the sensible or the latent load will dominate the control strategy and, in particular, the use of the outdoor air in free-cooling or the load reduction by interzonal airflow.
Cooling equipment that can efficiently meet latent load independent of sensible load will realize the energy savings potential of improved building designs.
5 = the cooling load contribution of the product to the latent load of the case
Cooling equipment that can efficiently meet latent load independently of sensible loads can in practice realize the potential energy savings from improved building envelopes and equipment.
