What are the installation requirements?
A water-cooled centrifugal chiller requires careful planning and professional installation to ensure long-term performance, safety, and energy efficiency. For Aurashu water-cooled centrifugal chillers, installation requirements are defined around structural conditions, mechanical connections, electrical systems, control integration, and commissioning procedures. These guidelines help guarantee stable high-capacity cooling operation for large commercial and industrial HVAC systems.

1. Equipment Room Space & Layout
The chiller must be installed in a dedicated mechanical room with sufficient space for airflow, pipe routing, electrical panels, and future maintenance. Aurashu recommends designing around full front, rear, and side service clearance to allow access for compressor inspection, tube brushing, heat-exchanger maintenance, and control calibration. The room layout should accommodate chilled water pumps, condenser water pumps, cooling towers, valves, filters, and electrical cabinets.

2. Structural & Foundation Requirements
Because centrifugal chillers are heavy machines, a reinforced concrete foundation with vibration-absorbing pads or spring isolators is required. The floor must support static and dynamic loads and remain level to ensure proper alignment. For multi-story buildings, vibration transmission and noise control should be evaluated during early design.

3. Condenser Water System Requirements
A stable and properly sized condenser water system is essential for efficient operation. This includes cooling towers, condenser pumps, water strainers, balancing valves, measuring points, and bypass lines. Aurashu chillers are optimized for standard condenser water temperatures (e.g., 30–35°C), but the system must deliver adequate flow, pressure, and water quality to maintain heat-exchange performance. Proper pipe sizing and routing reduce friction loss and enhance overall efficiency.

4. Chilled Water System Requirements
Chilled water piping must be insulated, pressure-rated, and installed with proper support. The system requires pumps, air vents, expansion tanks, buffer tanks (if needed), and safety valves. Flow stability is crucial because centrifugal chillers depend on minimum water volume and constant flow to avoid surge. Aurashu units can integrate variable-primary-flow (VPF) control, but minimum flow limits must be respected.

5. Electrical Power & Protection
Centrifugal chillers use large motors, often medium-voltage, so installation requires appropriate power supply, overload protection, grounding, and dedicated breakers. Voltage stability is essential for reliable operation. Aurashu’s intelligent control system supports soft-start or VFD-start depending on configuration, but wiring must meet local electrical codes.

6. Control & BMS Integration
Chillers must interface with building management systems (BMS) via MODBUS, BACnet, or other protocols. Controls should monitor temperatures, pressures, flow, alarms, pumps, and cooling tower fans. Aurashu systems can be integrated for centralized monitoring, predictive maintenance, and energy optimization.

7. Water Treatment System
High-quality water treatment equipment is required to prevent scale, corrosion, and biological growth. Poor water quality reduces efficiency and shortens equipment life. A professional water treatment plan is necessary from installation through operation.

8. Ventilation & Drainage
Mechanical rooms must have proper ventilation to dissipate motor heat and maintain ambient temperature levels. Floor drains and sloped flooring support safe and easy condensate and service water removal.

9. Safety & Compliance
Installation must meet local safety codes involving pressure vessels, lifting and handling, electrical isolation, and emergency stop devices. Aurashu provides safety documentation and commissioning support to ensure compliance.

10. Factory Commissioning & Performance Testing
Final steps include vacuuming and charging refrigerant if required, verifying pump operation, testing sensors, balancing water flow, and ensuring stable operation under different load conditions. Aurashu technical specialists can assist with on-site commissioning to guarantee optimal performance and energy efficiency.
