Experiments on the ventilation efficiency of turbine ventilators used for building and factory ventilation

Turbine ventilator is an equipment that uses natural wind force to exhaust airflow ; such ventilators are widely installed in Taiwan to enhance building and factories ventilation. In theory, the combination of turbine ventilator with natural ventilation improves the indoor air quality while it decreases the reliance on air-conditioning. So that allows a reduction of the energy consumption.A variety of tests on different types of ventilators was conducted. The results proved it is helpful to increase ventilation with the installation of ventilators.
