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 when compared to a portable hvac. Also, the mechanism is much small cooler less complex than an hvac, so it will require 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 by way of a 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 may not be so simple to understand, but the process is one that we experience every time we sweat. On a hot day, sweat evaporates away from your skin causing the same endothermic reaction as an evaporative air cooler does. Another example is leaving a swimming pool on a breezy and hot day. Even though the temperature may be over one hundred degrees, the water rapidly evaporating away from your body will make you feel cold or cold. An old-fashioned hvac uses a liquid like Freon to absorb the warmth. It then dumps the warmth not in the area being cooled through air flow. An evaporative air cooler instead cools the air along with endothermic reaction described.

Evaporative air coolers are better suited for dry climates. More water can be evaporated in dry air than in humid air, making these much more effective when humidness is low. Also, unlike when using an old-fashioned hvac, the area being cooled should not be sealed up. The area should be ventilated so the humid air produced by the cooler can be carried away and replaced by drier air.

Since a swamp cooler takes in water, a sufficient water fish tank size should be considered. The rate at which an evaporative air cooler takes in water is around half a liter an hour depending on the humidness level, so a six to ten liter fish tank is recommended. An evaporative air cooler should have an fresh air of at least 500 cubic meters per hour. Brands, such as the SPT evaporative air cooler cooler may offer other features this kind of ionizer or ice delivers. These additional features exercise . cost, but prices for a portable evaporative air cooler is always below an equivalent portable hvac. Plus, they are cheaper to run as well as.
