märgjahutid

Märgjahutid, also known as evaporative coolers or swamp coolers, are a type of air conditioning system that cools air through the evaporation of water. This process utilizes the principle that when water evaporates, it absorbs heat from its surroundings, thereby lowering the temperature of the air.

The basic operation of a märgjahuti involves a fan drawing warm outside air through a water-saturated absorbent material, often a porous pad made of wood fibers or cellulose. As the air passes through the wet pad, water evaporates from its surface, cooling the air. The cooled, humidified air is then blown into the space.

Märgjahutid are most effective in hot, dry climates where the relative humidity is low. In humid environments, their cooling capacity is significantly reduced because the air is already saturated with moisture, limiting the rate of evaporation. They are generally more energy-efficient and less expensive to purchase and operate than traditional refrigerant-based air conditioners.

The components of a typical märgjahuti include a fan, a pump to circulate water to the cooling pads, a water reservoir, and the cooling pads themselves. Maintenance typically involves cleaning or replacing the cooling pads and ensuring the water reservoir is kept filled and clean to prevent the growth of mold or bacteria. They are commonly used in residential, commercial, and industrial settings, particularly in regions with arid climates.
