摘　　要：本文理论分析了住宅用新风换气机结霜的原因,计算得出避免换热器结霜的新风最低温度值;实验测定了该换气机的性能及其结霜与室内温湿度变化规律,并与理论计算值进行比较分析得出:考虑室内温度变化,将结霜点定在-5℃是比较经济合理的。This text has analysed the reason for forming the frost of the air renewal ventilator of new wind deeply, the new wind minimum temperature value of forming the frost of the heat exchanger has been calculated out through the theory. I should determine the air renewal ventilator＇s property and the rule that frost with the change of temperature and humidity indoor through the experiment, the result is analysed and compared with the theory calculating value, the conclusion is that the knot frost of the air renewal ventilator will be set up in-5 degrees Centigrade when we conside the indoor temperature changes.
