Drying Laundry Indoors
Laundry may be dried indoors rather than outdoors for a variety of reasons including:
- inclement weather
- physical disability
- lack of space for a line
- reduce the damage to fabrics from sun's UV rays
- legal restrictions
- to raise the humidity level indoors, and lower the air temperature indoors
- convenience
- to preserve privacy
Several types of devices are available for indoor drying. A drying rack or clotheshorse can help save space in an apartment or clothes lines can be strung in the basement during the winter. Small loads can simply be draped over furniture or a shower curtain pole. The drying time indoors will typically be longer than outdoor drying because of the lack of direct solar radiation and the convective assistance of the wind.
The evaporation of the moisture from the clothes will cool the indoor air and increase the humidity level, which may or may not be desirable. In cold, dry weather, moderate increases in humidity make most people feel more comfortable. In warm weather, increased humidity makes most people feel even hotter. Increased humidity can also increase growth of fungi, which can cause health problems.
An average-sized wash load will convert approximately 3165 joule of ambient heat into latent heat that is stored in the evaporated water. To determine how much heat has been converted in drying a load of laundry, weigh the clothes when they are wet and then again after the clothes have dried. The difference is the weight of the water that was evaporated from them. Multiply that weight in kg by 2,257, which is the heat of vaporization per kilogram, to obtain the number of Kjoules that went into evaporating the water, or multiply by 0.6250 to get kilowatt-hours. (Note: If the moisture later condenses inside the house, the latent heat will be converted back into ambient heat which could increase the temperature of the air in the room slightly.) To obtain a good approximation of the effect this would have in a particular situation, the process can be traced on a psychrometric chart.

Famous quotes containing the words drying and/or laundry:
“Just as petals fall from drying garlands, which you can see aimlessly swimming in wine-bowls are we lovers, who now puff up our chests, but perhaps tomorrow the fateful day will shut us down.”
—Propertius Sextus (c. 50–16 B.C.)
“Education is a necessity, it helps to understand life. Like that compagnero in Cuba who talked about politics, back when they were on strike. He knew many things, that hijo de puta, and he unraveled the most confusing situations in a marvelous way. You could see each point in front of you on the line of his reasoning like rinsed laundry set up to dry; he explained things to you so clearly that you could grasp it like a good hunk of bread with your hand.”
—Jacques Roumain (1907–1945)
