If nonconditioned out of doors air is unintentionally drawn throughout a surface area which is chilled sufficiently by air-conditioned indoor air, condensation will arise. Inside the cooling period, that is certainly almost certainly to happen when an exhaust lover or the return facet of the air handler lowers indoor air strain in rooms or depressurizes wall or ceiling cavities (Brennan et al., 2002).
