| Abstract |
In Korea, it is the law that an apartment building which consists of over 100 households must have a ventilation system installed, either natural or mechanical. The heat recovery ventilator (HRV) is great way to reduce energy consumption. In this research we confirmed that based on site’s construction plan and existing diffuser form, performed purpose CFD which simulates operation in temperatures below -5℃ to circumstances of installation of an HRV in an apartment. As a result of this research we found that when the diffuser’s aperture area was adjusted, the distribution of air temperature and residence time of air was more equally distributed and air temperature was higher, compared to when the diffuser has an identical aperture area. We also found that we are able to increase even more air temperature and air distribution of air temperature and residence time of air was even more equally distributed when run in parallel with a splitter damper. |
