| Quantity: | |
Key Features:
Compact Design: Integrated with fans, condensers, compressors, and evaporators, air-cooled chillers are self-contained units, requiring minimal installation space.
Energy Efficiency: Advanced scroll or screw compressors, paired with optimized airflow systems, ensure reliable performance with reduced energy consumption.
Low Maintenance: Eliminates the need for cooling towers, water pumps, and piping, lowering operational and maintenance costs.
Versatile Applications: Widely used in industrial processes, HVAC systems, commercial buildings, data centers, medical facilities, and food/beverage production.
Environmentally Friendly: Modern models utilize eco-friendly refrigerants (e.g., R407C R134a) compliant with international regulations (e.g., EU F-Gas Directive).
Operation Principle:
The refrigerant absorbs heat from the process water in the evaporator, converting it into gas. The compressor then pressurizes the gas, raising its temperature. In the air-cooled condenser, fans blow ambient air over the coils, releasing heat and condensing the refrigerant back into liquid. The cycle repeats to maintain consistent cooling output.
Advantages Over Water-Cooled Systems:
No water consumption or wastewater disposal concerns.
Ideal for arid regions or indoor installations.
Simplified installation and scalability for setups.
Technical Specifications:
Cooling capacity: 10 kW to 2,000 kW (customizable).
Temperature control range: Typically -10°C to 30°C, depending on design.
Weather-resistant construction for outdoor operation in harsh climates.
Air-cooled chillers are a robust solution for industries prioritizing sustainability, operational simplicity, and adaptability to diverse environmental conditions.
