摘要：
The flow rate of air infiltration and corresponding influencing factors were measured and analyzed. The air exchange rates with different heating methods and temperature difference between the indoor and outdoor air were tested in the experiment room by using the tracer gas method. The test results show that the air exchange rate in heating room increases by 35%-40% compared with that without heating when the temperature difference between the room and the outside reaches 6-8 °C under the same conditions of the airtightness of doors and windows. As to the influence of the heating methods on the air exchange rate, it is slightly larger when the room is heated by supplying hot air than that in the room with radiant floor heating methods. The increase in the air infiltration caused by space heating should be considered when designing the residential heating system in this region. © 2019, Zhejiang University Press. All right reserved.
