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.

The radiant panels and DOAS work together by "decoupling the space sensible load and utilizing the DOAS ventilation approach to address the outside air latent load," the researchers explain.
The coil bypass air-handling unit addresses this problem by taking only a portion of the air across the coil, all of the outdoor air that is likely to require dehumidification, and a portion of the recirculated air determined either by the sensible or the latent load within the space.
The mixed air passing the cooling coil handles the space latent load and the mixed air bypassing the cooling coil maintains the required minimum airflow set point.
From the investigations and simulation method, the application of PCM in the building as passive materials will greatly reduce the use of operation energy, increase the latent load and reduce the annual C[O.
The DOAS is responsible for bringing outside air into the building and also takes care of the latent load from the outside air.
This reduced the latent load on AC system and cut the humidity that had previously caused musty smell.
Cooling the air controls both latent load and sensible heat gain.
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.
In Boulder's temperate, dry climate, there was little latent load to support biofouling on the test coils, and the results showed a correspondingly low impact of coil UVGI.
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.
