A Research of a Bidirectional Ventilation Device to Improve Indoor Environment

摘要

Under the condition of closed the interior door and window, the device displaced the indoor and outdoor air and recycled the energy of air exhaust. The paper takes consider as the separate air-conditioning office of the bidirectional heat pipe ventilation device and establishes the corresponding calculation model through the numerical simulation experimental research on typical winter climates, the device's ventilation rate has effect on the concentration of carbon dioxide. When the ventilation rate respectively is 40m~3/h. 60m~3/h. 80m~3/h, the concentration of carbon dioxide of breathing zone is 1102ppnK 868ppnu 789ppm. However, the concentration distribution of carbon dioxide of breathing zone is uniform when the minimum ventilation rate is 49.8m~3/h.
