Industrial High Efficiency Forced-draught Air Cooled Exchanger / Air Cooler
What is an air cooler?
An air cooler, also known as an evaporative cooler or swamp cooler, is a device that cools air through the natural process of water evaporation. Unlike air conditioners (ACs), which use refrigerants and compressors, air coolers are energy-efficient, eco-friendly, and ideal for dry climates. They are widely used in residential, commercial, and industrial settings due to their cost-effectiveness and simplicity.
Yuhong Group is a professional enterprise specializing in the production of air coolers, heat exchangers and pressure vessels, if you have any demand please feel free to contact us.
Working Principle
Air coolers operate on evaporative cooling:
-Warm air is drawn into the cooler by a fan.
-The air passes through water-saturated cooling pads, where water evaporates, absorbing heat and lowering the air temperature.
-The cooled, humidified air is then circulated into the room.
-This process works best in low-humidity environments, as dry air enhances evaporation efficiency.
Key Components
Cooling Pads: Made of absorbent materials (e.g., cellulose or wood shavings) to hold water.
Water Reservoir: Stores water, often with a capacity of 10–50 liters.
Water Pump: Circulates water from the reservoir to wet the pads.
Fan: Draws air through the pads and distributes cooled air.
Control Panel: Adjusts fan speed, timer, and cooling modes.
Types of Air Coolers
Portable: Compact, movable units for homes or small spaces.
Window-Mounted: Fixed in windows for localized cooling.
Industrial: High-capacity units for factories, warehouses, or outdoor events.
Hybrid Models: Combine evaporative cooling with ice compartments for enhanced cooling.
Advantages
Energy Efficiency: Consumes 80% less energy than ACs (typically 100–200 watts).
Cost-Effective: Lower purchase and operational costs.
Eco-Friendly: Uses water, not harmful refrigerants.
Humidity Boost: Ideal for arid regions, improving indoor air comfort.
Ventilation: Works best in open spaces, allowing fresh air circulation.
Disadvantages
Climate Dependency: Less effective in high-humidity areas.
Water Use: Requires regular refilling and maintenance.
Maintenance Needs: Pads and reservoirs need cleaning to prevent mold or bacterial growth.
Limited Cooling Range: Cools areas by 10–15°F (5–8°C) in dry climates, less in humid regions.
Applications
Residential: Homes, apartments, and patios.
Commercial: Offices, shops, and outdoor events (markets, sports venues).
Industrial: Factories, workshops, and greenhouses.
Temporary Use: Construction sites or emergency cooling.
Comparison with Air Conditioners
Cooling Method: Air coolers use evaporation; ACs use refrigerants.
Energy Use: Air coolers consume far less electricity.
Humidity: Coolers add moisture; ACs dehumidify air.
Environment: Coolers are greener (no CFCs).
Space Suitability: Coolers excel in dry, open areas; ACs work in sealed, humid environments.
Maintenance Tips
Regular Cleaning: Replace/clean cooling pads monthly; disinfect tanks to prevent algae.
Water Management: Use clean water, drain when not in use, and descale if needed.
Inspect Components: Check pumps and fans for functionality.
Seasonal Storage: Dry the unit before long-term storage.
Conclusion
Air coolers offer a sustainable, economical cooling solution for dry climates, combining simplicity with effectiveness. While they have limitations in humid regions, their low energy use, environmental benefits, and versatility make them a preferred choice for many users. Proper maintenance ensures longevity and optimal performance.
