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.

These equations assume that all of the moisture indicated by the latent load ends up on the coil.
The proposed method consists of an airside system handling the latent load with the thermally activated building system controlling the sensible load.
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.
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.sub.2] emissions.
This will be done by combining a liquid desiccant cycle (which deals with the latent load) with a traditional vapour compression cycle (which faces the sensible load).
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.
In the process air side, the room air that includes the sensible and latent loads moves to the DW to remove the latent load.
In the moisture conservation equation (Equation 6), w is the moisture concentration, [[??].sub.gen] represents the mass flow rate of the humidity generated in the space, and [[??].sub.HVAC] represents the mass rate removed by the AC system resulting from the latent load.
This kind of air system takes away moisture-generating latent load." Removing moisture from the air and reducing the humidity level avoids condensation.
Conventional HVAC systems are designed to control both room temperature (the "sensible load.") and humidity (the "latent load") while providing sufficient fresh air to dilute pollutants generated by building occupants and equipment.
