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.
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.
