Relative humidity summer vs winter
WebDec 21, 2024 · If it's 40F/69%RH in the attic and the outside air is 35F/85% RH the out door air is more humid than the attic air. Active ventilation under those conditions would bump the indoor RH to 70% @ 40F. An RH of 69% @ 40F isn't a mold hazard, but at 90F it is. WebHumidity is a measurement of the amount of water vapour in the air. Find out more about the different types of humidity. Atmospheric humidity is a measure of water held in the air as a gas. Water can be solid (ice), liquid (water) or a gas (vapour). The vapour component makes up about 99% of all water held in the atmosphere.

WebIf the temperature is 25 degrees C and a cubic meter of air contains 22 grams of water, then the relative humidity is 100 percent. If it contains 11 grams of water, the relative humidity is 50 percent. If it contains zero grams of water, relative humidity is zero percent. The relative humidity plays a large role in determining our comfort level. WebHumidity: Average Relative Humidity. Relative humidity (RH) is the amount of moisture in the air as a percentage of the amount the air can actually hold. Warmer air can hold more moisture than cooler air, which means that for a given amount of atmospheric moisture, RH will be lower if air is warm than it would be if the air is cool. This can be ...
