Coleman帐篷内部冷凝是装备问题吗

Raining inside my tent - gear issue or skill issue?

摘要

楼主每年秋季飞营一两次，今年在密歇根湖Fox Island露营。去年购入Coleman Carlsbad 6人darkroom帐篷带门廊，虽防风雨防虫，但即便开窗也持续在帐内冷凝水，睡垫和睡袋都被打湿。当时气温白天70多华氏度、夜间40多至50多华氏度，湿度不高但夜间低于露点。楼主问是装备问题还是使用问题，并求帐篷推荐，还提到可能换用Crua Duo Maxx。

所以我每年会飞出去露营一两次，通常是在秋天，去一个长周末。今年是在 Fox Island，位于 Lake Michigan 中 Beaver Island 以南约 20 miles 处。去年我买了一个 Coleman Carlsbad 6 person darkroom tent with porch，虽然它作为一顶耐候帐篷还不错，也不会让虫子进来，但它不断在帐篷内凝结水汽，即使把所有窗户都打开也一样。天气最高在华氏70度出头，最低在40多度到50度出头，不算特别潮湿，但低温降到了露点以下。我的问题是，是我的装备不行，还是有什么办法能缓解我醒来时发现帐篷、气垫床和睡袋变成临时集水器的情况？有帐篷推荐吗？我可能还有一个 Crua Duo Maxx 可以换着用，如果它更好的话。

So I fly camp once or twice a year, usually in the fall for a long weekend. This year it was on Fox Island, about 20 miles south of Beaver Island in Lake Michigan. Last year I procured a Coleman Carlsbad 6 person darkroom tent with porch, and while it's fine in the sense of being a weather-durable tent and not letting bugs in, it condensed water into the tent constantly, even with all the windows open. Weather was high in the low 70s, lows in the mid-40s to lower 50s, not overly humid, but the lows got below the dewpoint. My question is, is my gear bad, or is there something I can do to mitigate waking up to my tent, air mattress, and sleeping bag becoming an impromptu water collector? Any recommendations for a tent? I also might have a Crua Duo Maxx I could switch to if it's a better option.

评论区观点评论区主要认为冷凝更可能是选址问题而非装备问题，尤其草地和靠近水域容易导致湿气；建议把帐篷移到树下、铺不外露的地布、拉紧所有防风绳并增加通风，也有人推荐用电池风扇。发帖人表示下次会尝试移到树林下。

你露营的地方离水有多近？一般来说，有些帐篷选址非常容易导致冷凝。靠近水边、在草地上，或者靠近沼泽区域，都会带来大量湿气。

How close to water do you camp? There are generally tent placements that are highly prone to causing condensation. Close to water, on grassy meadows, or near swampy areas are all going to yield a lot of moisture.

这次大概在水面上方100ft，距离水边700 feet以内。整个岛只有一英里宽，所以其实没有“别在水边露营”这个选项。

This was about 100ft above and within 700 feet of water. The whole island is a mile wide, so there really isn't a "don't camp near water" option.

高出100ft其实相当不错了。问题更多是像“高出5 feet、距离10 feet”那种。地形本身呢——比如草地、地面本身是否潮湿、附近有没有潮湿区域？

100ft above is actually pretty good. Problems are more like "5 feet above, 10 feet away". What about the terrain itself - e.g. grass, the ground itself being damp, nearby moist areas?

草地，大概200x3000ft，被桦树/松树林包围。没有可见的低洼/潮湿区域或水源。

Grass field, roughly 200x3000ft, surrounded by a birch/pine forest. No visible low-lying/damp areas or sources of water.

草地很可能就是原因，夜间草地蒸腾出的水分多得惊人。可以考虑把帐篷移到桦树/松树下面。那会减少从下方来的湿气，也会减少上方的温差（因为树木提供了一定程度的保暖）。

Grass field is likely to be it, night time prespiration from grass is surprisingly significant. Consider moving the tent under the birches / pines. That will reduce moisture coming from below you, and also reduce contrast from above (as trees provide some degree of warmth).

下次我会试试。我通常会把帐篷扎在飞机旁边，因为以前的营地没有靠近树林的选项，但这次本来是可以的。谢谢！

I'll give that a try for next time. I usually camp by the plane because there wasn't an option to camp near the woods at previous sites, but that would have been viable this time. Thanks!

希望有用！我特别知道要避免草地扎营，尽管它们看起来很方便舒适。否则选址就会变得很奇怪。我在徒步进入的偏远野外环境里通常用单层帐篷。我见过帐篷*最干*的一次是……在一个小湖旁边、悬崖顶上，当时正下着大雨。关键主要是那个小湖的位置导致雾气从不聚集（它只会从悬崖滚落到大约50 feet外的山谷里），地面没有蒸腾（只有一堆岩石和石楠），而且下雨带来了有风的天气，这也让表面温度稳定得多。最湿的……一直都是在草地上。

Hopefully it works! I specifically know to avoid grassy setups despite their apparent coziness. Otherwise site selection gets weird. I typically use a single-wall tent in hike-in backcountry environments. The *driest* I have seen my tent was ... next a tarn, on top of a bluff, during a significant rainstorm. The key was largely that the tarn position resulted in fog never collecting (it would just roll off the bluff into the valley about 50 feet away), no perspiration from the ground (just a bunch of rocks and heather), and the rain brought windy conditions which also kept the temperatures a lot more consistent on surfaces. The wettest ... has always been on grass.

在帐篷下面铺地布，但不要伸出来到可能积水的地方，这有助于应对冷凝。多一层来隔开地下水。确保每一根防风绳都完全打好地钉，防止雨罩或帐篷各层互相接触，这会影响通风和冷凝。如果我知道会下雨或潮湿，我会尽量把帐篷扎在两棵树之间，并在上面搭一块天幕：https://www.westcoastpaddler.com/community/attachments/e1ffae80-7e38-4a64-99f4-35cb2dcd2380-jpeg.7592/ 这样你可以增加通风。最后，一个电池供电的风扇可以帮助应对帐篷内部的露点和冷凝。一个 Ryobi、Dewalt 或某种工具风扇可以用普通工具电池整夜运行。

Ground sheet under the tent, but not sticking out such that it could possibly collect water helps with condensation. Extra layer against the ground water. Make sure every single guyline is fully staked out, to prevent rain fly or tent layers from contacting each other which affects ventillation and condensation. If I know it's going to rain or be damp, I would try to get my tent between 2 trees and put a tarp over it: https://www.westcoastpaddler.com/community/attachments/e1ffae80-7e38-4a64-99f4-35cb2dcd2380-jpeg.7592/ This way you can increase ventilation. Lastly a battery powered fan can help with dew point and condensation from inside the tent. A Ryobi, Dewalt or some tool fan can run all night on a common tool battery.
