Why does a desert cooler cool better on a hot

On a hot dry day, quantity of water vapours is low in atmosphere by which rate of evaporation is increased. Strong wind is flown by running cooler and due to atmospheric heat the rate of evaporation is increased. Therefore while running desert cooler the temperature of room gets cold.

Evaporative cooling is a natural and energy-efficient cooling process that uses the evaporation of water to lower the temperature of the surrounding air. It works on the principle that when water evaporates, it absorbs heat from the air, resulting in a cooling effect. In an evaporative cooling system, a fan draws warm outside air through moistened pads or media, where the water evaporates, cooling the air. This evaporation process requires heat, which is absorbed from the surrounding air molecules, resulting in a drop in temperature. Desert coolers are based on the simple principle that when dry air comes into contact with water, the water begins to evaporate. This evaporation process leads to the release of water vapor, which is then expelled outside the cooler through a fan, creating a cool and moist air stream. While the moisture content in the air increases, the temperature decreases, resulting in a refreshing cooling effect. The effectiveness of a desert cooler depends on the climate conditions, particularly the humidity levels. Evaporative cooling is a natural and energy-efficient process that uses water evaporation to cool the surrounding air.

Why does a desert cooler cool better on a hot

Byju's Answer. Question 1 Why does a desert cooler cool better on a hot dry day? Open in App. When a liquid evaporates, the particles of the liquid absorb energy from the surroundings to compensate for the loss of energy during evaporation. Since evaporation causes cooling, this makes the surroundings cool. In a desert cooler, the water inside it is made to evaporate. This leads to absorption of energy from the surroundings, thereby cooling the surroundings. Evaporation depends on the amount of water vapour present in air humidity. If the amount of water vapour present in air is less, then evaporation is more. On a hot dry day, the amount of water vapour present in air is less.
