The Hanbell AC-1320 is a high-performance, dual-circuit screw chiller designed for applications where capacity, energy efficiency, and operational reliability are paramount. Its intelligent design provides both the power for large-scale cooling demands and the flexibility to operate efficiently under varying loads, making it a strategic choice for modern, cost-conscious facilities.
Technical Parameters
| Model | Power (kW) | Rotating speed (rpm) | Air Delivety (m3/min) | Shaft power (kW) | Specific power (kW/m3/min) | Dimension(mm) | Weight(kg) |
| AC-1320 | 132 | 3000 | 21.83 | 142.4 | 6.52 | 863*610*442 | 490 |
High-Efficiency Twin-Screw Compressor Unit:
Features Hanbell's semi-hermetic twin-screw compressor, optimized for large cooling capacities and high-pressure operation.
Engineered with precision-machined rotors and high-load-bearing components for durability under continuous heavy-duty operation.
Dual-Independent Refrigerant Circuit Design:
The AC-1320 model typically incorporates two independent screw compressor circuits within a single, compact chassis.
Each circuit operates autonomously with its own compressor, control system, and necessary components, providing built-in system redundancy and excellent turn-down capability.
Optimized High-Capacity Heat Exchangers:
Equipped with large, high-efficiency shell-and-tube evaporators and condensers.
Designed for maximum heat transfer efficiency and low refrigerant-side and water-side pressure drops, minimizing pumping and compression energy.
Advanced Centralized Control System:
Utilizes an industrial-grade programmable logic controller (PLC) with a graphical touch-screen interface for comprehensive system management.
Provides features such as adaptive capacity sequencing, detailed system diagnostics, fault logging, and extensive BMS (Building Management System) communication capabilities (e.g., Modbus, BACnet IP).
Enables remote monitoring and control for efficient facility management.
Integrated Energy-Saving Technologies:
Standard or optional variable frequency drives (VFD) on compressors allow for smooth, stepless capacity modulation from approximately 25% to 100%.
High-efficiency, electronically commutated (EC) fans on the condenser for optimal air-side performance and reduced power consumption.
Robust Industrial Construction:
Heavy-duty steel frame and industrial-grade components built for longevity and reliable 24/7 operation.
Comprehensive safety and protection controls, including high/low pressure switches, motor overload protection, freeze protection, anti-cycle timers, and phase monitoring.
Compliance with Modern Standards:
Designed to operate efficiently with environmentally responsible refrigerants such as R-134a or lower-GWP (Global Warming Potential) alternatives.
Superior Part-Load Efficiency and Operational Flexibility:
The dual-circuit design, combined with VFDs, allows the chiller to match cooling load variations with exceptional efficiency. One circuit can be shut down during low demand, while the other operates at its optimal efficiency point, resulting in outstanding IPLV (Integrated Part Load Value) performance.
Enhanced System Reliability and Redundancy:
The two independent refrigerant circuits provide critical redundancy. If one circuit requires maintenance or experiences a fault, the other can continue to provide significant cooling capacity (typically 50%), ensuring continuity of operation for critical processes and reducing downtime risk.
Precise and Stable Temperature Control:
Advanced microprocessor control and modulating capacity ensure tight control of leaving water temperature, which is essential for sensitive industrial processes and modern HVAC systems.
Lower Total Cost of Ownership (TCO):
High energy efficiency directly reduces electricity costs. The robust design and reduced cycling (thanks to capacity control) lower maintenance requirements and extend the equipment's lifespan, contributing to a favorable TCO over the lifetime of the chiller.
Simplified Central Plant Design:
Offers a large cooling capacity in a single packaged unit, simplifying piping, electrical connections, and plant room layout compared to deploying multiple smaller chillers.
Large Commercial and Institutional Complexes:
Central cooling plants for major airports, large hospital networks, university campuses, and sprawling shopping mall complexes.
Heavy Industrial Process Cooling:
Automotive manufacturing plants, large-scale plastic injection molding and extrusion facilities, chemical and petrochemical plants, food and beverage processing facilities.
District Energy Systems:
As a primary or secondary chiller within a district cooling plant serving multiple buildings or a mixed-use development.
Mission-Critical Environments:
Support cooling for large data center clusters, pharmaceutical manufacturing cleanrooms, and semiconductor fabrication plants.
Large Hospitality and Entertainment Venues:
High-rise hotels, convention centers, and sports stadiums/arenas.
