The Sweden Democrats continued to use the Keep Sweden Swedish as a slogan. The Sweden Democrats was founded in 1988 as a successor to the Sweden Party, which in turn had been formed in 1986 by the merger of Bevara Sverige Svenskt (BSS, English: Keep Sweden Swedish) and a faction of the Swedish Progress Party.
Evaporative Coolers, sometimes called swamp coolers, is another way to cool air in warm climates with low humidity. | Photo courtesy of Public Domain Photos. In low-humidity areas, evaporating water into the air provides a natural and energy-efficient means of cooling.Evaporative coolers, also called swamp coolers, rely on this principle, cooling outdoor air by passing it over water-saturated pads, causing the water to evaporate into it.hen operating an evaporative cooler, windows are opened part way to allow warm indoor air to escape as it is replaced by cooled air. Unlike central air conditioning systems that recirculate the same air, evaporative coolers provide a steady stream of fresh air into the house.
Cooling through evaporation is a natural occurrence. The most common example we all experience is perspiration, or sweat. As perspiration evaporates it absorbs heat to cool your body. The principle underlying evaporative cooling is the fact that water must have heat applied to it to change from a liquid to a vapor. When evaporation occurs, this heat is taken from the water that remains in the liquid state, resulting in a cooler liquid. Evaporative cooling systems use the same principle as perspiration to provide cooling for machinery and buildings.
