Case Study
• Designing the heat exchanger with an optimal balance between heat transfer and pressure drop to minimize the total power consumption
• Keeping the size of the system within specified limits while reducing the total weight
• Selecting materials to last a minimum of 25 years in offshore environment
Solution Many months were spent on full-scale performance testing in Heatex ’ s test laboratory , proving that the system would provide adequate cooling power . In addition , more than ten different materials and coatings were tested to ensure sufficient corrosion resistance and durability ( 25 + years ). The cooling system consists of two units on each side of the nacelle . The outside air is pulled into the system via inlets and runs in a closed loop , ensuring the out-and inside air never mixes . The system was designed around Heatex ’ s modular cross flow heat exchangers for high heat transfer efficiency and low pressure drop . Fans were optimized accordingly to reduce total power consumption and weight . The framework was designed as an integrated part of the structure inside the nacelle , equipped with interfaces for transport , lifting , and service .
Results Verified Performance : 100 % verified cooling performance in full scale tests at Heatex ’ s own lab facilities . 700kW Cooling Capacity Cooling capacity in
Heatex team .
such a narrow space required highly efficient plate heat exchangers . Low Maintenance Costs : self-cleaning heat exchangers require minimal maintenance . High Cooling Capacity : heat exchangers , fans , and ducts were designed and tested as a complete system to avoid losses and secure high capacity . Moderate Power Consumption : fully adjustable power consumption was based on actual operating conditions and cooling needs . Solid Cooling Efficiency : plate heat exchanger technology contributes to increased heat transfer and overall efficiency .
