While selecting your personal air cooler, it is important to know which type will best suit your needs. Air coolers work best in low humid and hot areas. The Direct and Indirect Evaporative Cooling are the two basic types of air cooler designs. The air coolers are economic. catering both to your budget and need. They are noiseless and fill your room with cool, fresh air.



Your personal Air Cooler, also known as Swamp Cooler, is best suited to cool room temperatures in dry climates. They make use of either direct or indirect evaporative cooling techniques. The air cooler will work best in places where humidity is low and the air is hot, If you are in search of an air cooler, you may easily get confused due to the huge variety of products available in the market. Thus, it is essential to judge your requirements before you start searching for an air cooler.

Features Of Your Personal Air Cooler

The air cooler comprises a fan centered inside a box. It consists of a number of pads made of PVC or wood shavings that are present on the fan's suction side. Water is supplied to these pads with the aid of a small water pump. The pads are constructed in such a way that they break the water into smaller droplets. As the fan sucks in air, these water droplets cool the air that enters the box. Thus, your personal air cooler comprises a box, a fan, a pump, few pads and an air distributor to ensure that the cooled air is equally distributed in the room.

Air Cooler Designs

There are two basic designs for air coolers:

Direct Evaporative Cooling - Also referred to as open circuit, this design reduces air temperature by making use of latent heat during evaporation. Water is evaporated using the heat in the air without altering the energy in the air.

Indirect Evaporative Cooling - This closed circuit design is almost similar to the direct evaporative method in the sense that it also lowers room temperature by making use of latent heat. But the air that is cooled does not come in direct contact with the cooler.

In most cases, the air coolers make use of direct evaporative cooling.They are either mounted on top of the roof or placed along the exterior sides of the walls. It is necessary to make a vent in the walls or the roof to allow constant air movement. It is also necessary to allow air circulation through the system, failing which the cooling efficiency will fall due to air being saturated.

The Portable air coolers have a throw of around 10 feet. There are other portable air coolers with larger cooling capabilities, but in most cases they are noisy. The lightweight portable air coolers have smaller water holding capacity and can work at a stretch for around 15 hours.

Advantages Of Personal Air Cooler

The personal air coolers have a number of advantages over the other cooling mediums. If your budget is low, the air coolers are best since they are economic with low initial cost. Even the cost of operation is less than air conditioners. The constant intake of air ensures that your room is constantly filled with fresh air. Moreover, they are noiseless and ensure an unperturbed sleep.
