What is a Falling Film / Flooded Water-Cooled Chiller?
A Falling Film / Flooded Water-Cooled Chiller is a high-efficiency central cooling system designed for large-scale commercial, industrial, and process applications requiring stable, high-capacity chilled water. It utilizes a flooded evaporator design, where refrigerant fills the evaporator shell at a low level and continuously wets the tube surfaces. In falling-film configurations, refrigerant is evenly distributed over the tube bundle in a thin film, significantly enhancing heat transfer compared with traditional dry-expansion evaporators.
This design provides greater heat exchange efficiency, higher evaporation temperature, and reduced compressor power consumption. As a result, falling film and flooded chillers deliver exceptional performance in medium- to high-tonnage systems and achieve lower kW/ton values, making them one of the most efficient water-cooled chiller technologies.
Aurashu falling-film and flooded chillers are engineered with optimized heat-exchanger geometry, precise refrigerant distribution, high-efficiency screw or centrifugal compressors, and advanced control algorithms to maximize system performance. The flooded evaporator ensures more surface area is actively utilized, allowing the unit to run with lower lift and reduced energy consumption, especially under part-load conditions.
These chillers are widely used in large commercial complexes, industrial manufacturing, data centers, pharmaceuticals, electronics production, automotive plants, chemical processing, and other environments where long-term stable cooling and low operating cost are essential. They also support integration with free-cooling systems, thermal storage, heat recovery, and intelligent building automation.
Aurashu provides extensive project customization options, including capacity range, refrigerant selection, heat-exchanger configuration, corrosion-resistant materials, high-efficiency variable-speed compressors, and optimized system control strategies. With advanced safety protection, redundant monitoring, and professional engineering support, Aurashu ensures reliable long-term operation, high system stability, and reduced lifecycle cost for mission-critical cooling applications.
