Product Introduction:
Liebert® SDC3 Smart Dual‑Cycle Energy‑Saving Unit is an air‑conditioning unit that makes full use of outdoor free‑cooling resources to reduce energy consumption. It realizes conventional cooling and energy‑saving cooling within one single refrigeration system with a highly integrated design, and adopts environment‑friendly R410a refrigerant.
Apart from mechanical compression cooling mode and low‑temperature energy‑saving cooling mode, SDC3 is equipped with an additional mixed‑mode cooling function. Mixed cooling mode can be activated when the outdoor temperature ≤ 20℃. The variable‑frequency pump assists compressor operation to cut compressor power consumption, and improve the system’s cooling capacity and energy efficiency ratio.
