High Efficiency Falling Film Chiller and Heat Pump Unit | Energy Saving with Falling Film Evaporator
Lower refrigerant charge – More environmentally friendly and cost-effective.
Improved oil return – The falling film design minimizes oil retention, ensuring better compressor lubrication and reliability.
Compact footprint – Smaller evaporator size saves valuable machine room space.
Wide capacity range – Available from 100 kW to several MW, suitable for projects of all sizes.
Our Falling Film Chiller and Heat Pump Unit is a state-of-the-art water-cooled system that integrates advanced falling film evaporation technology. This design significantly improves heat transfer efficiency while reducing refrigerant charge, making it more reliable and energy-efficient than traditional flooded-type units.
At the core of this unit is the Falling Film Evaporator. Unlike flooded evaporators where refrigerant fully submerges the tube bundle, the falling film evaporator distributes refrigerant evenly over the outside of the tubes via a patented spray system. A thin liquid film forms on the tube surface, allowing for extremely efficient heat exchange. Any excess refrigerant collects at the bottom and is recirculated. This design reduces the refrigerant charge by up to 50% compared to a flooded evaporator, lowering both cost and environmental impact.
As a Water Cooled Heat Pump Unit, it provides both cooling and heating functions, making it ideal for applications that require simultaneous temperature control. It is widely used in large commercial buildings, hospitals, data centers, pharmaceutical cleanrooms, and industrial processes.
The High Efficiency Chiller Heat Pump achieves a COP (Coefficient of Performance) significantly higher than conventional chiller systems. With falling film technology, the unit operates with a lower temperature difference between refrigerant and water, enhancing overall system efficiency. Real-world tests show energy savings of 20–30% compared to standard flooded chillers.
Additional benefits of our Falling Film Chiller include:
