发帖数: 405 | 4 firelog 你指的是那种starter吗？那玩意一次用一点就行了，不用整根的烧。木头要
交错摆，下面垫点报纸。要把报纸揉皱了，别放一沓子。然后扔几块starter。damper
半开比较好：不至于热量都从烟囱跑了，或者燃烧不完全。如果门底下有vent要打开，
这样空气可以进去，不至于产生太多CO。有火的时候最好旁边有人，别让它着着就去睡
觉了。前面如果是地毯的话铺个防火的垫子,好像叫hearth mat，防止火星溅出来烧坏
地毯。烧完了的木头多过些天才能清理，否则容易死灰复燃。我听说有人过了3，4天清
理，掏出来的灰还是把垃圾桶点着了。这个比较夸张，不过小心些好。 |

1. The fireplace should not take air from the indoors, that is, it should
have an in-take airway from outdoors.
2. Glass doors to keep exhaust from escaping the fireplace and room air from
sucking into the fireplace.
3. The right damper size to control the airflow.
4. Better aerodynamic in flue to prevent sucking in cold air.
The newer one might have more
1. Grate heaters.
2. Reflectors.
3. Catalytic features. |

发帖数: 4125 | 12 You can get a powerful inline fans and tie it into existing your bathroom
exhaust pipe, put in 2 dampers, so you can control it to suck from either
kitchen or bath or both. Not the best or most powerful, but you do not have
to make any new holes. |

windows, doors, walls, etc.
If you live in more harsh climate, house will be build "tight", you will
need some kind of air exchange system, otherwise you will die from lack of
oxygen. My house have a system that is capable of exchange all its air
between 6 to 30 times per day. (it is variable based on indoor air quality,
there is a sensor in every room and send the info to control and it will

发帖数: 215 | 15 We had same issue the other day. I turned on the furnace for a couple of
minutes and the sound was gone. It seems that the noise is from the pressure

in my case. I live in New England area. |

发帖数: 4125 | 19 No.
Dual zone can be just 1 compressor, but have 2 thermostat that can control
the damper in the duct work to decide how much air to deliver to each zone.
Newer high efficient system can have 2 compressor for even just 1 zone house. |

central air conditioner,只有一个空调机，但楼上楼下各一个温度测试调节器，可以

问镇上inspector或者黄页上的pro能不能改成户外进气 不过要这样改的话 这个
utility room就得算unconditioned 和其它conditioned space之间要加insulation..

那个算是个damper吧 furnace排废气时 就自动掀开了 往里面进气来稀释高温废气
降温 不排时 就自动掉下来盖上 |

发帖数: 14763 | 34 Technically speaking, you should let all the exhaust out through the chimney
, as you don't want CO, soot, and other stuff in the exhaust. If you have a
glass front, keep it shut and use the damper to control the burning rate.
The heat you can take from the fireplace is only the radiation and that
absorbed by the hearth, which releases the heat to the room in a slow way
even long after the fire is gone. Yes, the heat in the hot exhaust is lost,
that's why the fireplace is considered an inefficie... 阅读全帖 |

或者厨房remodel的时候必须使用有管道通到外面的抽油烟机。如果你所在地方有这个
code的话完全可以和HOA讨论。HOA是不能要求你违反code的，也就是说HOA必须同意你
打洞的。
我最近研究了一下标准，好像不是你说的这样。标准说：如果使用抽油烟机，要么是直
排，要么是排到室外。没有说一定要使用有管道通到外面的抽油烟机。也没说一定要有
抽油烟机。
看本地code:

2、冬天把楼上的空调口调小，把楼下的空调口调大。夏天正好相反。为什么呢？因为
热空气往高处走，冷空气往底处走
3、在utility room房间，furnace周围看一下，某些空调管（铁皮的ductwork）上可能
会有一个扳手，用来控制管内的damper，可以从源头上调节往楼上和楼下的送风量
4、把某些不常用区域的空调口可以考虑关起来，或者封起来。亚马逊有软磁的东东可
以直接吸上去

如果是空调口在墙上担心磁性不够容易脱落的话，这个是强磁的
