SKC Series Magnetic Bearing Refrigerant Pump Multi-Split Unit

The magnetic bearing refrigerant pump multi-split system is a highly energy-efficient medium- to large-capacity precision air conditioning system based on refrigerant pump multi-split technology. It is suitable for temperature control applications in data rooms with stringent PUE requirements, such as medium- and large-size data centers, Colo data centers, and Internet companies. The system incorporates oil-free magnetic bearing variable frequency technology, evaporative cooling technology, variable frequency refrigerant pump technology, and terminal multi-split technology, enabling it to operate continuously in the most energy-efficient mode. The system mainly consists of three parts: the outdoor main unit, condenser, and indoor unit. The main unit covers a cooling capacity range of 300kW to 600kW. Depending on local climate and hydrological conditions, it can be flexibly configured with either an evaporative condenser or an air-cooled condenser. The system can operate in three cooling modes: compressor mode, compressor-pump hybrid mode, and refrigerant pump free-cooling mode. Based on ambient conditions and load demand, it automatically adjusts the operating mode to make full use of natural cooling sources and improve the overall annual energy efficiency ratio. The main unit can be flexibly paired, either separately or simultaneously, with various terminal types, including room-based units, in-row units, rear-door units, and air walls. This allows the system to accommodate multiple application requirements and provide customers with an efficient and reliable temperature control solution.
