I am trying to re-route my household fresh air intake to run under the ground and enter near the basement floor in order to warm it up in the winter and cool it down in the summer. I live in Wisconsin. I presently bring fresh air into the house constantly and route it to my furnace cold air return. For underground routing, I am concerned about radon gas and water getting into the tubing. I am also concerned about contamination of the air from the tubing.
谢谢，

丹尼斯，
Your concerns are appropriate. Buried earth tubes have so many disadvantages that they are rarely installed these days -- and with good reason. Here is more information:Belgian Passivhaus is Rendered Uninhabitable by Bad Indoor Air。
Thank you Martin,
我阅读了这篇文章，至少部分地看到了该系统如何失败。
I was considering running a pair of 4" diameter CPVC pipes (rated for potable water and covered with a screened rain cap) vertically downward until 6 feet deep and then running them horizontally for 15 feet except pitching them downward and then taking a 90 degree turn into the basement wall a foot above the basement floor. The CPVC joints would be glued. I was going to add a drain fitting inside the basement to drain any condensation from the summer. I was also planning on dumping some bleach/water mixture down the pipes from outside once a year to make it uninhabitable for mold. This design is affordable. Still, I share your health concerns. Assuming that water/mold is prevented, I am not sure about the CPVC being safe for the air.

您可以通过地面运行一个线圈，并在进入返回管道之前使用它来预热空气。可能有点不那么危险，但更复杂。安装HRV可能会更便宜。目前的系统是否会让你感到不舒服？房子的通风率是否正确？我所看到的大多数房屋都有通风率套装高......
Thank you for the idea Jesse,
我现在看看你的意思;将一些流体从进气口循环到地面。进入的空气将热升起来接触线圈。实际上，我唯一不喜欢的是我需要使用能量来运行泵。

I measured the incoming air rate to be 75CFM, which is what I think is appropriate. The present system is working out fine. I am just trying to reduce the energy use.

I was considering an "earth tube" or a version thereof as well Dennis. From what I've found websearching the issue, its not such a good idea after all. From what Jesse suggests, it sounds like a form of geothermal? I am not that knowledgable on such systems, but an underground coil that is used to heat or cool air sounds like a form of geothermal, no? If you look into it and find anything worth while let me know. At a minimum sounds like you'd be running a pump and a fan.
嗨Dennis：UltimateAir制作一个附件，一个12英寸水到空气线圈模块，它连接到其收纳仪200dx erv。该模块可以连接到地面回水/流体管，冬季预热和除霜，并预先改装。夏天凉爽和脱湿，进入他们的ERV。检查出来：http://www.ultimateair.com/Portals/92089/docs/6825_Water-to-Air-Coil-Module-Installation.pdf例如，55F入口水可以将室外进入的空气预热至31F进入ERV，缓解ERV需要进入除霜模式。类似地，50F入口水可以将95F进入的95F进入67F-72F范围内的进入ERV（参见上面的链接中的表PP。5和6）。水模块的水提供冷凝水排水。应对水/流体泵（2.5或5GPm为典型）和地环的安装成本来称量节能。
WONDERFUL!
1995年在县机场,3200英尺的垂直boring with 3/4 U-Paired tubing delivered not less than 7 useable TOTAL cooling tons and 4% DEHUMIDIFICATION exchanging 80-deg office air with 52 degree boreholes x 240 ft depths + headers in 5ft trenches combined, borehole static water was ~ 40ft deep in a standard grouted GEOTHERMAL 98% RENEWABLE installation. the 1.1/2hp circulator was quite less costly allowing a barely comfortable work area during construction.

Please note any standard water in piping : Headers are for purging on occaision if your loops and headers are normally operating under 2.2ft per sec where almost all micro 'cling-ons' air bubbles clinging to smooth plastics, etc, are found that need then to be moved out of the piping at over 2.1-2.2 fps. Some 1/2" exchangers of piping coils have required over 2.2 fps.
Jon,
