发帖数: 14763 | 1 You mean, for a wet basement, right? Because we can't install a sump pump
for a wet backyard.
Improving drainage is more desirable. Sump pump can remove the water in your
basement, but the hydrostatic pressure is still on your wall, along with
the humidity, it can does a number on your cement basement. |

Tape a small patch of film on the ground, and observe which side the water
is on. If it's on the upper side, then it's condensation, and try to reduce
the humidity (again, in most cases, there's not much you can do except
installing a dehumidifier.) |

发帖数: 15836 | 7 I set mine to stop at 60%. I feel quite comfortable with it and have no

is: if your basement humidity level is 70% or higher, it is better for you
to have one. |

Temp setting (on thermostat) will determine when ac compressor work and how
often they work, they help lower the temp and also take out humidity.
Compressor use a lot more electricity than the blower fan.
If your house is zoned, turning fan to on all the time will not help much
and could waste more electricity.
If you have a multi-story house with only one ac unit, leaving the fan on

发帖数: 55 | 12 The house we are interested now has a dehumidifier running in the basemen.
After yesterday pouring rain (~80F), we did not see any wetness but the
dehumidifier was showing 72% RH and seems like the owner set the target to
60% RH. and it has a pipe to drain the water to outside.
Is this humidity normal? I heard anything beyond 60% RH is getting into
dangerous zone of growing mold?
Thanks a lot! |

发帖数: 15836 | 14 Basement is usually colder than above ground, thus more condensed water and
higher humidity level than above ground. Also, it has more chance to have
leakage from outside environment from cracks etc. In addition, the
ventilation in the basement is usually not as good so the water in the air
can not be easily taken out. So it is more likely to have mold in the
basement before it affects the above ground building, and it is less likely
to be detected because usually people don't use basement as mu |

Surprisingly statistics from both NOAA , and Cityrating.com show that Los

Albany, New York. It is hard to believe because the air in L.A. does not
have that hot, sticky feeling that air in east coast cities has. Perhaps
this phenomenon is because the air in Los Angeles usually comes off the
ocean and is cool compared to air over land masses where the sun has had
time to warm it. Until I resear... 阅读全帖 |

HVAC (Heating, Ventilation, and Air Conditioning) refers to technology

subdiscipline of mechanical engineering, based on the principles of
thermodynamics, fluid mechanics, and heat transfer. Refrigeration is

Yes, or you can safely leave it burning. The pilot helps keep the moisture
