Cost Effective Comfort Giving HumidifiersEven in winter, inside warm buildings, we need some amount of humidity to be at ease. During the cold season the humidity indoors can be very low. It results in dry skin and problems related to mucous membranes. It also makes one feel colder than what it really is. Low humidity also adversely tells on anything wooden inside the house - furniture of flooring. It also increases static electricity and one gets a spark upon touching metals. For this reason you need to make use of a humidifier in order to increase the comfort level. Humidity is the moisture in the atmosphere. When it rains we say that the humidity is high. The desert atmosphere has very little humidity. There is water vapour in air. The amount of water depends on the air temperature. Warmer air holds more water. Thus relative humidity refers to the relation between air temperature and the amount of water it can hold. If the air temperature is 25 degrees C and there is 22 grams of water then it is said that humidity is 100%. At this point water will not evaporate - the air is saturated. The cooling of our body depends on evaporation of moisture from the skin. The lower the humidity the easier it is for evaporation of moisture to make us feel cooler. A humidifier will control this factor of humidity. It costs less to humidify than to warm air. It is a money saving device. The ideal for indoors is 45 % humidity.. The typical humidifier is simple and self-regulatory. A vessel contains cold water that is dispensed into a container. A wick filter absorbs the water from the second container or the basin. A fan then blows air from the filter that has been moistened. The air that is passing through this filter evaporates some amount of water. When humidity is high the more difficult it is to evaporate. As humidity rises the water vapor from the humidifier decreases. Hence it is said to be regulating itself. Evaporative humidifiers are often linked to the heating and or the cooling system of the house. A metal screen is fixed in the channel coming from the air-conditioner or furnace. Water that is flowing from the pipes flow past the screens while air coming form the channels blow across these screens. En route moisture is picked up. There are many devices to increase humidity. Place a vessel of water on top of a stove or the radiator and voila - it works. Another way is to hang thick wet towels near the duct of a heater. Generally people opt for mechanical humidifiers. A vaporizer or steam humidifier boils water and releases the steam into the room. A medicated inhalant can be introduced in these models. The other models are impellers and electronic humidifiers. |
