Experimental Validation of Moisture Transfer at different Leakage Areas and Pressure Gradients
A detailed understanding of moisture with its specification that has dependency on several parameters i.e. relative humidity, outdoor enthalpy, climate zone, and functioning of a space is the driving force to decipher the performance of latent load. A thorough grasp of simulation and its respective back calculations to predict moisture transfer and latent load from different sources through building physics and formula derivation. A gap between the theoretical study of latent load and its applicability in terms of designing HVAC systems, wall assemblies and material selection whilst incorporating moisture transfer during simulation. With the method of substitution, to include moisture transfer through infiltration is still arbitrary, and only one aspect of the latent load is considered in a space i.e occupant latent load. The importance and impact of moisture in a space, where temperature is easily tackled with cooling advancement but dampness in a space is hard to resolve. A new criterion of pressure gradient is added to observe the change in moisture behavior in a space. The criteria would be a deciding factor in assuming the tightness of a building and the resultant infiltration rate assumption for simulation to determine latent load with accuracy.
