Description

Modular Dual-cold Source Computer Room Precision Cooling Solution


Product Advantages
Dual cooling source configuration with one backup, manual/auto switching, stable and reliable system, high control accuracy.
High energy efficiency ratio (EER): Air-cooled units ≥3.0, water-cooled units ≥3.4, freezing water units ≥20. Custom products with higher EER available based on customer needs.
High sensible heat ratio design.
Modular units with universal internal parts, cost-saving for users.
Large cooling capacity with a small footprint, space-saving for equipment.
Easy transportation, disassembly, and assembly on site, solving size limitations.
Units can be installed closely or separately, addressing local overheating and space constraints.

Chilly Source Combination Methods
Modular Dual Cold Source Computer Room Precision Cooling Solution Large Capacity
The KMT.S unit of the Lingyun series has three different chilly source combination methods. Among them, KMA+KMU and KMW+KMU are both combinations of one fluorine system and one chilled water system, while KMU+KMU is a combination of two chilled water systems. Each chilly source system can operate independently without affecting each other, and can be manually or automatically switched, offering higher control accuracy.
In the air-cooled and water-cooled systems, the indoor fan drives air through the air-conditioning evaporator, transferring heat to the refrigerant. In the air-cooled system, the outdoor condenser removes heat through air, while in the water-cooled system, a plate heat exchanger or shell-and-tube heat exchanger removes heat through water.
The chilled water system is supplied with chilled water by the main unit, and the chilled water coil removes heat from the air.
