Key Features of the Water-Cooled Screw Chiller
1. Semi-Hermetic Screw Compressor
Our chiller uses a semi-hermetic screw compressor supplied by leading brands like Zhejiang and Han Zhong. This compressor provides:
- Stable and Low-Vibration Operation: Ensures consistent performance and reliability.
- Low Noise: Reduces overall sound output, contributing to a quieter environment.
- High Efficiency: Achieves over 20% energy savings compared to traditional scroll compressors.
The screw compressor’s design includes a stepless capacity control, which adjusts the cooling capacity between 25% to 100%, allowing precise energy management and stable operation.
2. Shell and Tube Evaporator
Equipped with a shell and tube evaporator, the chiller maximizes heat exchange efficiency. The key elements include:
- High-Efficiency Copper Tubes: Seamless copper tubes with internal thread fins increase the surface area for refrigerant interaction, effectively doubling the heat transfer rate.
- Optimized Water Flow: A 2mm thick baffle plate enhances water movement, creating a brine solution for stable, low-temperature operation.
- Insulated Shell: Maintains consistent temperatures and minimizes energy loss.
3. Shell and Tube Condenser with Embossed Copper Tubes
Our water-cooled screw chiller’s condenser uses a high-efficiency design:
- Outer Thread Embossing: Embossed copper tubes increase the heat exchange surface area, improving thermal conductivity and heat transfer speed.
- Enhanced Heat Exchange: Allows the refrigerant to efficiently transfer heat to the water, promoting quick and consistent cooling.
4. Advanced Control and Automation
Integrated with RS485 communication, this chiller seamlessly connects to data management systems for real-time monitoring and automated control. This feature enables remote operation, making it suitable for complex, interconnected industrial settings.
5. Energy Efficiency and Variable Frequency Drive (VFD)
Our chiller is equipped with ABB VFD technology, enabling precise control of cooling capacity and reducing power consumption:
- Variable Frequency Drive (VFD): Adjusts capacity from 1% to 100%, meeting fluctuating cooling demands.
- Soft Start Feature: Reduces the initial startup current, minimizing electrical impact and enhancing unit longevity.
- Built-in DC Reactor: Lowers harmonic interference, ensuring stable operation across a range of conditions.
- Integrated Part Load Value (IPLV): Achieves a high IPLV of approximately 10, ensuring energy savings exceeding 30%.
