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 just a portable hvac small room cooler. Also, the mechanism is much less complex than an hvac, 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 through 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 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 cool or cold. An authentic hvac uses a liquid like Freon to absorb the warmth. It then places 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 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 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 overly enthusiastic and replaced by drier air.

Since a swamp cooler needs water, an acceptable water water tank 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 water tank 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 kind of ionizer or ice bags. These additional features exercise . cost, but prices for a portable evaporative air cooler is always below what an equivalent portable hvac. Plus, they are cheaper to run as well as.
