Best Evaporative Air Coolers Buying Guide
Evaporative air coolers, also known as swamp coolers, are an energy-efficient way to cool your home using the natural process of evaporation. Unlike traditional air conditioners that use refrigerants, evaporative coolers rely only on water and air to produce a cooling effect.
As hot air passes through the saturated cooler pads, the water evaporates and absorbs heat from the air, causing it to cool. The cooled air is then blown into your home, providing relief from heat and lowering the temperature. Evaporative coolers are best suited for dry, arid climates where humidity levels are low.
Factors to Consider When Buying an Evaporative Air Cooler
Type of Evaporative Cooler
There are two main types of evaporative coolers:
Portable evaporative coolers: These are usually small, wheeled units that can be moved from room to room. They are best for spot cooling and supplemental cooling.
Whole-house evaporative coolers are designed to be permanently installed on the roof or wall and connected to ductwork to distribute cool air throughout the home. This type provides whole-home cooling.
Cooler Size
Properly sizing your evaporative cooler is crucial for it to work effectively. An undersized unit will not provide adequate cooling, while an oversized one wastes energy. The general rule is to get a cooler that provides 15-20 air changes per hour for the room or home’s square footage. Consult the manufacturer’s sizing guidelines.
Water Source
Evaporative coolers require a constant water supply. Options include:
- Connecting to your home’s plumbing line
- Using a water line kit with an external tank
- Manually fill with a hose as needed
If using a tank, calculate the water consumption and choose one that meets your needs without frequent refilling.
Airflow
Higher airflow equals greater cooling capacity. Measure the room’s cubic feet and look for CFM (cubic feet per minute) ratings to match the space. Variable speed settings allow adjusting the airflow as needed.
Cooling Pads
The corrugated cooling pads are key to evaporative cooling. Look for pads made of cellulose or aspen for effectiveness and durability. The pad’s saturation level impacts cooling, so look for units with effective water distribution.
Filtration System
A good filtration system removes dust, pollen, and impurities from the air for cleaner, healthier air circulation. Activated carbon and antimicrobial filters are recommended to filter smaller particles.
Energy Efficiency
Evaporative coolers consume much less energy than traditional AC units. Look for Energy Star-rated models for the highest efficiency. Programmable timers help save energy by running when needed.
Added Features
Added convenience features include electronic controls, remote operation, casters for portability, automatic water fill, pump protection, and a thermostat.
Conclusion
When selecting an evaporative cooler, carefully evaluate the type, size, water source, airflow, cooling pads, filtration system, energy efficiency, and features to choose the model that best suits your climate, cooling needs, and budget. Proper sizing, efficiency, and well-functioning parts will ensure optimal cooling at a low cost. With a quality evaporative cooler, you can beat the heat without the heavy energy burden of traditional air conditioners.
Frequently Asked Question
How do evaporative air coolers work?
Evaporative air coolers work by drawing warm air through water-saturated pads. As the air passes through these pads, the water evaporates, which cools the air. The cooled air is then circulated into the room, providing relief from heat.
Are evaporative air coolers suitable for all climates?
Evaporative air coolers work best in hot and dry climates where humidity levels are low. In humid climates, the effectiveness of evaporative cooling diminishes as the air already holds moisture, limiting the evaporation process. However, they can still provide some cooling in moderately humid conditions.
How much water do evaporative air coolers consume?
The water consumption of evaporative air coolers varies depending on factors such as the size of the unit, the climate, and the frequency of use. On average, smaller units can consume around 2-3 gallons of water per hour, while larger units may use up to 10 gallons or more. It’s essential to monitor water levels and refill as needed to ensure continuous operation.
Are evaporative air coolers energy-efficient?
Compared to traditional air conditioners, evaporative air coolers are generally more energy-efficient. They consume less electricity because they do not require compressors or refrigerants to operate. However, the energy efficiency also depends on factors such as the size of the cooler, the climate, and the desired cooling level.
Can evaporative air coolers be used indoors?
Evaporative air coolers can be used indoors, but proper ventilation is essential to ensure effective cooling and prevent humidity buildup. They work best in open or partially open spaces where there is adequate airflow. Additionally, regular maintenance, such as cleaning the pads and ensuring proper water drainage, is crucial to prevent mold or bacterial growth indoors.
