   I can choose between 30pint/day, 50pint/day and 70 pint/day units from the same manufacturer, all are energy star rated

   骑自行车的罚款有些罚款 - 当它闲置时，蒸发器从寒冷到室温，因此，在除湿才能重新开始之前，已经花费了能量将其恢复原状。如果您将更高效率的大型单元与低效率小型单元进行比较，我仍然选择大型单元，但是鉴于所有单元的评分相同，我希望最小的一个能量会稍低，因为它会少循环。

   也许很小的一个优点是，如果它不足以保持湿度在所需的位置，那么您将有动力找到水分的水分（气泄漏或水分从混凝土中流出）并减少来源。如果您的两者都足够低，那么即使是小的除湿器也很少运行，也应该能够保持低湿度。

   @ Charlie
   You make some very good points, the crawlspace is responsible for most of the air leakage and humidity entering the house (realized from the energy audit blower door and noticing humidity tracks outdoor humidity/temperature in a predictable manner).
   But after crawling in there and getting very dirty i can't find actual gaps the air comes through though the floor above does get ice cold in winter confirming it is the crawlspace, and the rest of the basement is brick walls and concrete floor, which are not appreciably damaged but do suffer from mild efflorescence.
   我打算坚持使用大型除湿机，但我更喜欢较小的除湿器，我现在可以重新考虑，但是我负担不起工程师来确定我是否可以挖掘并挖掘爬网空间，而且它太不均匀了用于塑料，挖出不足以轻松访问。
   According to the EPA at 700 sq/ft (2/3 basement, 1/3 crawlspace) should need 23 pints at full load, however i cannot be sure my house fits their models
   我打算明天去，所以我需要决定

   鉴于所有水分的来源都是无意的，因此很难估计它们有多大。EPA尺寸桌子只是一个粗略的指南。

   Since the efficiency penalty for a larger size is small, and the uncertainty in the size needed is large, I'm now thinking I'd opt for at least the 50 pint model.

   That was my conclusion as well, i bought the 70 pint on sale a few weeks ago, it was out of stock, so they are supposed to call me when it comes in, the 30 pint is on sale this week for 10% less then the 70 pint, i could easily get either one, if i had an old dehumidifier and had numbers to work with i could say if the 30 pint would suffice because i would prefer it if it does.
   具有讽刺意味的是，50品脱是最昂贵的选择！
   在这一点上，最好的选择似乎是保持70品脱:(

   For anyone who comes across this thread looking for advice, learn from my mistake, there is an energy penalty to over sizing the dehumidifier, i bought the 70 pint (choice between 30 and 70) and after 7kW it has taken out about 4L of water, even though its rated at 1.85L/kW.
   基本上，这似乎取决于这一点，风扇在低处使用了77W，高度在81W上使用，因此大多数能量似乎都用于风扇（在较小的单元上可能会少瓦数），并且只有在当时才有评级。压缩机的湿度差异很大。因此，一个较小的单元可能使用较小的风扇，并且在更高的占空比上运行，这两者都会提高效率

   感谢您的报告，对不起，我们没有设法避免您不幸的选择。你可以退还吗？

   并非所有的除湿器都会在压缩机循环循环时保持风扇。可能很难确定我们从在线目录页面上的框中的框，但是有些人甚至可以切换风扇是否持续。

   Even without the constant-on fan issue, you can't expect to get the rated L/kWh in practice, because it depends on the humidity and temperature you are operating in. They are rated at 80 F, 80% humidity (if I remember right), which is an unrealistic choice--if it's that hot, you'd want to be air conditioning instead, and presumably you want to get the humidity lower than 80% in steady-state.

   风扇功耗听起来像一个典型的low-efficiency single-phase induction motor--way more energy use than it should have and using almost the same power on low as on high. An ECM fan motor might use 40 W on high and 10 W on low for the same airflow. Too bad the energy star threshold is set low enough that it doesn't force that upgrade.

   我可以退还它，但是现在销售已经消失了，对于较小的单位来说，它的价格将近100美元:(
