中国多形态零售模式下 用于商用制冷高效环保解决方案 ——卡乐(CAREL)节能环保解决方案
This document discusses refrigeration solutions for China's evolving retail landscape. It begins by outlining trends in Chinese retail like the integration of online and offline commerce. It then discusses the development of refrigeration needs, including more efficient systems for higher-end stores and reliable solutions for lower-tier cities. The document introduces CAREL's direct current inverter water system as a flexible, efficient and environmentally-friendly option that reduces noise and installation complexity. It provides details on the system's components and control technologies that enable energy savings and reliability. Finally, the document outlines CAREL's CO2 transcritical solutions and their advantages over traditional systems in various climates through technologies like parallel compression and ejectors.
