| Outline of Final Research Achievements |
A “heat recovery hybrid ventilation system” is the combination of passive stack ventilation and mechanical push-pull ventilation. Two heat storage boxes are connected to the natural EA stack and the underfloor natural OA duct. The alternation is done periodically in a way of that the outdoor air is drawn through one of 2 boxes contains heat storage material and the indoor air is exhausted through the other box. After the heat in the exhaust air is stored in the box connected to the stack in time of the natural ventilation, the stored heat is recovered by the supply air in a time of the mechanical backward ventilation. The heat capacity of the heat storage box and the control algorithm are decided by the experimental study and the model simulation. The measurement results in the test house show that the heat recovery efficiency is about 60%.
