Just before drinking, a tab is pulled so that the desiccant comes into contact with the liquid and dissolves. As it does so, it absorbs an amount of heat energy called the latent heat of fusion. 霧化機 related process, sublimation cooling, differs from evaporative cooling in that a phase transition from solid to vapor, rather than liquid to vapor, occurs.

Air cooler

Air coolers are eco-friendly –Air coolers use water for cooling and do not use any refrigerant such as CFC for cooling as is the case in air conditioners. To use the air cooler power consumption calculator to calculate the power consumption of your air cooler and interpret the results properly you should understand the following terms. Power consumption of a 200 watts air cooler running for 5 hours in a day is 1 kWh of electricity per day and 30 kWh of electricity per month. The T120 provides powerful cooling and discreet style in an easy-to-install CPU air cooler.

Passive direct evaporative cooling can occur anywhere that the evaporatively cooled water can cool a space without the assist of a fan. This can be achieved through use of fountains or more architectural designs such as the evaporative downdraft cooling tower, also called a “passive cooling tower”. The passive cooling tower design allows outside air to flow in through the top of a tower that is constructed within or next to the building.

Core function of evaporative cooler

While the concept of evaporating cooling has been around for a long time, the root of Air conditioning dates back to the second century China. During this time is when an inventor known as Ding Huane designed a rotary fan that was manually powered. The concept of air cooling was also used by Benjamin Franklin, an American inventor and statesman, to conduct several experiments involving evaporation and alcohol while trying to attain freezing temperatures. However, the first modern air conditioner was designed by Willis Haviland Carrier in 1902. Mass production of evaporative coolers began around the year 1939. Most designs take advantage of the fact that water has one of the highest known enthalpy of vaporization values of any common substance.

Before the advent of modern refrigeration, evaporative cooling was used for millennia, for instance in qanats, windcatchers, and mashrabiyas. A porous earthenware vessel would cool water by evaporation through its walls; frescoes from about 2500 BCE show slaves fanning jars of water to cool rooms. Alternatively, a bowl filled with milk or butter could be placed in another bowl filled with water, all being covered with a wet cloth resting in the water, to keep the milk or butter as fresh as possible . NasGas is a Pro-Pakistani home appliances’ manufacturer that has been in the market since 1952. They manufacture some of the best room air coolers, washing machines, dryers, geysers, and much more.
