To resolve indoor air pollution such as CO2 concentration problems that threaten the health of the occupants as well as to minimize the ventilation load that occupies a large portion of the cooling and heating loads, recently, the air-conditioning industry of cooling buildings including general houses has attracted much interest in Energy Recovery Ventilators (ERV). The commercially available ERV shows relatively good performance in general outdoor conditions, but condensation occurs inside the device from a humid climate in summer or a low temperature in winter, causing problems such as mold and rust. In this paper, the actual condensation occurrence ratio of South Korea was derived according to the latent effectiveness, and the outdoor conditions in which such condensation occurred were analyzed. As a result of summer simulation, the condensation occurrence ratio of Seoul/Busan was approximately 4.9%/12.9% at 0% latent effectiveness, and 0.7%/3.0% at 10%. In Seoul and Busan, condensation rarely occurs when the latent effectiveness is more than 20%. As a result of the winter simulation, the condensation occurrence rate of Seoul/Busan is approximately 84.9%/51.6% at the latent effectiveness of 0%. In the case of Seoul, as the latent effectiveness increases, the condensation occurrence rate slowly decreases, and then rapidly decreases from 30%. Condensation rarely occurs at 80% or more. In the case of Busan, it decreases linearly, and condensation rarely occurs at 70% or more. |
