Abstract 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.

夏热冬冷地区供暖房间冷风渗透影响因素
对夏热冬冷地区住宅房间供暖时的室外冷风渗透量及影响因素开展实测研究. 采用示踪气体法,在实验房间中测试不同供暖方式及室内外温差情况下,房间换气次数的变化规律. 测试结果表明,在相同的门窗密闭情况下,当供暖房间室内、外温差达到6~8 °C时,换气量比无供暖时增加35%~40%;在相同的室内、外温差下,采用对流送风方式时的房间换气次数略大于采用地板辐射供暖时的换气次数;在该地区设计住宅供暖系统时,应考虑采用不同的供暖方式对室内、外温差引起的渗风量增加的影响.
