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).
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.
Features of Dual Coil Unit
High Reliability (Core Advantage)
Dual cooling source redundancy design
Avoids system downtime due to single point of failure.
Significant Energy Savings
Utilizes natural cooling sources, reducing compressor running time
Especially suitable for cold regions or areas with large diurnal temperature variations.
Precise Control
Temperature control accuracy: ±1℃
Humidity control accuracy: ±5%
High Level of Intelligence
Automatic switching of operating modes
Supports remote monitoring (BMS/Modbus)
