Spending a day out at the beach under the hot sun sounds fun, but when the heat makes your home uncomfortable, buying an evaporative cooler may be your best move. You should be mindful of the following before placing an order for a unit:
- Targeted environment: The type of evaporative air cooler you will buy will primarily is dependent on the environment you intend to use it in. For outdoor use, larger and more rugged air coolers are advisable. When it comes to indoor usage for large rooms or halls, larger sizes are the typical recommendation. For smaller rooms, the more portable units should be used. Evaporative air coolers should not be used in humid environments.
- The brand: There are numerous brands on the market. It is best to stick with the well-known brands that have years of proven excellence in designing evaporative cooler units.
- Design: The design of any cooling unit is always essential, as it greatly impacts the cooling efficiency. For example, units designed with oscillating louvers can distribute air evenly in different directions more than those without oscillating louvers. Also, units with digital and remote controls are easier to use than the older models with knobs.
- Power consumption: Evaporative air coolers are known generally for their lower power consumption than air conditioners. You should look out for cooling units that consume less power than others.
- Inverter adaptability: If there’s a power failure, it would be great to know that you can plug in your air cooler to an inverter and cool your home! It is best to get a unit that comes with a rechargeable battery, or that is fully ready to be used with an inverter.
- Water efficiency: An evaporative cooler works by cooling air using evaporated water; water is a necessity. Some cooling units have a higher water efficiency than others. You should find such units to buy as water conservation is important to our world today.
- Air capacity: Evaporative air coolers are rated according to the volume of air they can deliver. This rate is measured in Cubic meters per Minute (CPM). Most air coolers have a CPM range of between 2500 – 13000. Knowing the size of the place you intend to use the unit will help you to determine the number of units that you need to meet the CPM.
You can always ask a technician to help you make a choice based on these considerations.
