摘　　要：作者在实验台上模拟实际运行条件,用标准条缝模拟新风保温阀,对新风保温阀冷风渗入量的影响因素进行了实验研究,分析了条缝宽度与条缝两侧压差对冷风渗入量的影响,指出对于高建筑无法避免的热压在新风保温阀两侧的压差中占主导地位,而提高新风保温阀的密闭性。The author has simulated the work conditions in lab and simulated the fresh air insulating valve with standard slot, then studied the influence factors of cold air infiltration though the slot of fresh air insulating valve by test, analyzed the influences of the width of the slot and the pressure difference between two sides of the slot on the volume of cold air infiltration, pointed out the thermal pressure between two sides of the fresh air insulating valve, which can not be avoid for high building, is the leading factor and it is the key for the solution of fresh air heater frozen to damage to rise the air tightness of fresh air insulating valve so that avoid cold air filtrating of treat the cold air by proper means.
