What is a Water-Cooled Screw Chiller?
A Water-Cooled Screw Chiller is a high-capacity central HVAC cooling system that uses water as the heat rejection medium and a screw compressor as its core compression component. It is widely applied in large-scale commercial, industrial, and infrastructure projects where high efficiency, stable operation, and long service life are required.
At Aurashu, water-cooled screw chillers are engineered as core cooling sources within complete chilled water systems, typically operating together with cooling towers, condenser water pumps, and chilled water circulation networks. Compared with air-cooled chillers, water-cooled screw chillers achieve superior energy efficiency by utilizing water’s higher heat transfer coefficient, especially under high ambient temperature or heavy-load conditions.
Working Principle
Aurashu water-cooled screw chillers operate on a vapor compression refrigeration cycle. The screw compressor compresses low-pressure refrigerant vapor into a high-pressure, high-temperature state. The refrigerant then enters a water-cooled condenser, where heat is transferred to condenser water and discharged through a cooling tower. After condensation, the refrigerant flows through an expansion device and evaporator, absorbing heat from the chilled water loop to provide cooling to air handling units, fan coil units, or process equipment.
Aurashu adopts high-efficiency twin-screw compressors, optimized refrigerant flow design, and precision control logic to ensure smooth capacity regulation and stable performance across wide load ranges.
