S & H系列涡旋压缩机,带IDV技术

为压缩机带来稳定性和系统可靠性的新高度:

• 中间排气阀:减少启动时机械部件的负荷，在较高的冷凝和蒸发温度下提供更安全的操作，有助于更好的液体管理
• 推力轴承和聚合物轴承表面涂层:提高压缩机在低润滑条件下的稳定性(启动时)
• 油气分离管  : 并联配置下，在部分负载时保持安全油位
• 成放电温度保护*:防止在操作外壳外操作
• 集成止回阀*:减少压缩机关闭后制冷剂从高压侧向低压侧的迁移
• 改进的气路(气流通道)和密封下轴承:提高淹没启动能力和整体压缩机对液塞的稳定性。在DSH 090至DSH 184上附加反向排气阀，防止在相位连接错误的情况下发生反向旋转损坏。在大型平台(DSH 240 ~ 485)上，由电子板进行监控。

15-120TR per Circuit

Today, almost 90% of all commercial scroll air conditioning systems use manifold compressors.

Compressors in manifold configurations offer:

• Flexibility in staging
• High part-load efficiency 
• Improved uptime 
• Low applied costs 
• Lower sound levels

Mastering the manifold designs over the years, Danfoss addresses the complex challenges that our customers face in extending their system capacities when using multiple scroll compressors. 

Our safe compressor operations with static and dynamic manifold piping design offers best in class performance under both full-load and part-load conditions. Each of the Danfoss large compressors is equipped with an oil equalization connector and oil sight glass rendering it ready for use in single, tandem or trio configuration with no additional cost. 

The Danfoss manifold configurations offer a wider capacity modulation. Our even and uneven manifold configurations up to 120TR in one circuit offer wide staged capacity modulation. For example, a system with six manifold compressors in two circuits offers capacity modulation from 17% to 100%. This enables higher part-load efficiency compared to screw technology in a system of equivalent capacity. Danfoss IDV technology, implemented in the 7.5-40 ton range of the fixed-speed Danfoss Scrolls DSH and Danfoss inverter Scrolls, further enhances energy efficiency under part-load conditions.

Mechanically, the sound level is also significantly lower than alternative compression technologies in larger capacities.
