![]() ![]() Aspen pads are made of wood shavings and synthetic fibre. Both have their advantages and disadvantages. Cooling pads are generally made of aspen or cellulose material. Thicker the cooling pad, the better the cooling. They absorb water and allow air to flow through them to cool it. Cooling PadsĬooling pads have a direct impact on the cooling of an air cooler. This feature is especially important for desert air coolers that are used in large rooms. You can also look for an air cooler with automatic louver movement, which ensures the flow of cool air in all directions. Most air coolers sport a three-speed regulator at the least. This lets you control the airflow, thereby controlling the temperature in the room. While buying an air cooler, you should also look for models that have multiple speed settings. Blowers on the other hand, can create high pressure airflow at high volumes, which is why they are used in smaller models. ![]() Fans can create airflow with low pressure but in large volumes they are usually used in big air coolers. The airflow of an air cooler also depends on whether it uses a blower or a fan. Then the CFM required would be 1,500 (300 sq ft x 10 ft/2). For example, if your room is 300 sq feet in size, with the ceiling at a height of 10 feet. You can calculate the required CFM by dividing the cubic feet of your room by two. You can choose the right size for the air cooler by calculating the CFM required for your room. The CFM denotes the amount of air cycled into your room each minute. Airflow of an air cooler is also measured in terms of CFM (cubic feet per minute). Just like an air conditioner, it’s important to buy an air cooler that fits the size of your room. Personal air coolers have tanks of 20 to 30 litre capacities while desert air coolers capacities range from 31 to 50 litres. Both desert and personal air coolers come with a wide range of water tanks sizes. A larger room would also require an air cooler with a larger tank. You need to select an air cooler that has a water tank that’s the right size for your everyday use. Larger the water tank, the longer the air cooler will run. It’s important to have air coolers that have large water tanks. In this method, water is converted into water vapour, which reduces the temperature of the air blown by the fan or blower. Water tank capacityĪir coolers make use of an evaporative cooling method. Once you have decided on the type of cooler you would want, you need to decide a model which best suits your needs. They have smaller water tanks but are capable of providing cooling for hours. They are known to consume less energy and are also quieter than desert air coolers. They are specifically meant to be used in small or specific areas of the room. Personal air coolers are more preferable for places that face humid weather conditions. Desert air coolers are more preferable if you want to use them outdoors, for example, on your terrace or backyard. They use large water tanks and have huge fans that can deliver cool air to the farthest corners of the room. They are usually larger than personal air coolers and are designed for cooling large rooms. Desert air coolersĭesert air coolers are mostly used in dry climate regions. They are both used in different climatic conditions. The two most popular types of air coolers are desert air coolers and personal air coolers. The evaporation of water in these cooling pads brings down the temperature of the air, which is then blown out by the fan. Air coolers make use of a simple air moving system that pulls fresh air from the outside and drives it through the wet cooling pads. They have a simple air cooling process which is no less effective than modern refrigerated air-conditioning technologies. How do they work?Īir coolers use a slightly evolved technique of evaporative cooling. In this article, we take a brief look at all the important features one should consider while buying an air cooler. There are plenty of options in the market and many more features to consider. Picking the right air cooler though can be a little confusing. They are popular because they are economical to use and are environmental friendly. Air coolers are one of the best cooling solutions for places that face dry summers. ![]()
