Korea has 4 distinct seasons, so heat recovery ventilators help to save energy. In the summer, indoor and outdoor temperature differences are relatively less than winter's. This is not a problem for the summer season and the change in temperature or location and installation of the heat recovery ventilation device. But, in winter, the temperature difference between indoors and outdoors is large. Thus, much moisture found in indoor air is released to the outdoors through ventilators. This condensation causes freezing problems that need to be considered. In this study, the effect on the moisture ventilator is analyzed by using two constant temperature humidity chambers that can be operated in winter for either indoor or outdoor environments. |
