How An Evaporative Air Cooler Or Swamp Cooler Works

A portable evaporative air cooler, or swamp cooler, is a great alternative for inexpensive cooling. These are both less expensive to purchase and less expensive to run than only a portable air conditioner. Also, small cooler the mechanism is much less complex than an air conditioner, so it should take less maintenance and upkeep.

An evaporative air cooler operates on the principle of an endothermic reaction. An endothermic reaction is a process that absorbs energy in the form of heat. The evaporative air cooler passes air via the wet media (wick). As the air passes through the water in the wick evaporates and the reaction causes heat in the air to be absorbed.

This isn’t always so an easy task to understand, but the process is one that we experience every time we sweat. On a hot day, sweat evaporates off from your skin causing the same endothermic reaction as an evaporative air cooler does. Another example is having to leave a swimming pool on a breezy and hot day. Even though the temperature may be over one hundred degrees, the water rapidly evaporating off from your body could make you feel cool or cold. An authentic air conditioner uses a liquid like Freon to absorb heat. It then places heat outside the area being cooled through ventilation. An evaporative air cooler instead cools the air by using the endothermic reaction described.

Evaporative air refridgerators are better suited for dry climates. More water can be evaporated in dry air than in humid air, making these much more effective when moisture content is low. Also, unlike when using an authentic air conditioner, the area being cooled should not be sealed up. The area should be ventilated so the humid air produced by the cooler can be overly enthusiastic and replaced by drier air.

Since a swamp cooler needs water, an acceptable water casual size is highly recommended. The rate at which an evaporative air cooler needs water is around half a liter an hour depending on the moisture content level, so a six to ten liter casual is recommended. An evaporative air cooler should have an setting up of at least 500 cubic meters hourly. Brands, such as the SPT evaporative air cooler cooler may offer other features this ionizer or ice back packs. These additional features add some cost, but prices for a portable evaporative air cooler is always under what an equivalent portable air conditioner. Plus, they are cheaper to run and maintain.
