Reasons Why IT Managers Should Consider In-Row Cooling for Data Centers

With latency-sensitive applications becoming widely distributed, IT companies increasingly rely on edge deployments and small and medium-sized data centres to crunch data closer to the end user. The coupling of InRow coolers and aisle containment provides greater precision cooling over old-fashioned data centre setups such as CRAC-based designs.

InRow cooler

In-row cooling technology is a type of air conditioning system commonly used for data centre cooling in which the cooling unit is placed between the server cabinets in a row to air to the server equipment more effectively. In-row cooling systems use a horizontal airflow pattern utilising hot aisle/cold aisle configurations and they potentially only need to occupy one-half rack of row space without any additional side clearance space.

In-row Data centre cooling solutions use a different architecture.  These units are positioned between the server cabinets and utilize a horizontal airflow pattern.  As a result, the cool air is aroused directly beside the servers creating heat. The cooling units pull the warm air exhaust air directory from the hot aisle, cool it, and then distribute it to the cold aisle.

This ensures that inlet temperatures become steady for precise operation. Coupling the air conditioning with the heat source generates an efficient direct return air path; this is called “close-coupled cooling,” which also reduces the fan energy required. In-row cooling also staves off the mixing of hot and cold air, thus improving efficiency.

1. Maintain predictable cooling architecture

In-row cooling is not affected by an increase in the racks’ power density. Which proves that in-row cooling is better suited for high power densities. Horizontal air flows are also less likely to recirculate throughout the physical space of the data centre, thus it allows for a greater concentration of cooling power.

2. Reduce footprint

Another key factor is that data centres often lack a raised floor to accommodate a vertical flow cooling approach. Because of their horizontal airflow design, in-row Data centre cooling systems don’t demand the overhead clearance needed for a conventional central air condenser. As these new data centres pursue a modular design approach, it only makes sense that the cooling system does too.

3. Lower energy costs

Leveraging in-row cooling units results in substantial energy cost savings and reduces the total cost of ownership compared to traditional perimeter-based cooling.

4. Continuous power availability

In-row cooling solutions open a new window and equip far greater resilience because the units work independently of one another and can easily be switched out in the event of failure by regular IT personnel.

The shift to the edge and small data centres demands a new cooling methodology. Right power’s in-row Data centre cooling system is designed for today’s small to midsize data centres, modular server rooms and edge-based locations. With advantages such as a compact and versatile footprint, enhanced cooling efficiency, inherent design resiliency and reduced energy costs, these in-row technology options are the perfect solution for this new modern era of data centre design.
