Dual Coil Unit

As data centers move towards green and low-carbon development, Dual Coil Units are gradually becoming one of the important technical approaches to reduce PUE (Power Usage Effectiveness).

Common Cold Source Forms of Dual Coil Unit

  • 1. Compressor Refrigeration (Main Cold Source)

    Based on a vapor compression refrigeration cycle, suitable for high temperatures or when natural cold sources are insufficient.

  • 2. Natural Cooling (Auxiliary Cold Source)

    Common forms include:
    Cooling water (cooling tower/chilled water system)
    Outdoor low-temperature air (wind-side natural cooling)
    Plate heat exchangers or dry coolers

*Under low ambient temperature conditions, natural cold sources can be used to directly remove heat, significantly reducing energy consumption.

Operating Modes of Dual Coil Unit

Mechanical Cooling Mode

Compressor operates only. Suitable for summer or high-temperature environments.

Natural Cooling Mode

Compressor shuts off, utilizing only an external cooling source. Significant energy savings (30%–70%).

Hybrid Cooling Mode

Dual cooling sources work together. Enhances cooling capacity and optimizes energy efficiency.

Redundancy Backup Mode

In case of failure of either cooling source, the other system automatically takes over. Ensures continuous operation 24/7.
