摘      要：The effects of vents on thermal ventilation to save energy in the cold rolling workshop of Baosteel were *** to the scale modeling theory,a small chamber was *** details about construction of experiment on thermal ventilation and the preparation and arrangement of apparatus were discussed,and then the effects of vents on thermal ventilation were studied through experiments,which includes the temperature distribution,the volume of ventilation,the temperature difference between inlets and outlets,the neutral plane,and the effective thermal coefficient of thermal natural *** on this,the effects of natural ventilation based on varied area of inlets and outlets and those of vents on one side and on different sides were *** to the experiments,the area of inlet vents and outlet vents affect the temperature distribution in chamber,and their effects on ventilation volume are different,but the effects of vents in single side or different sides are the same under the condition that only thermal ventilation is considered.
