Polargy offers an enhanced airflow solution portfolio that starts with Containment and integrates Monitoring and Control to achieve the optimal airflow balance and efficiency. These two together can dramatically and safely improve cooling energy efficiency.

The Case for Integrating Containment with Monitoring & Control

Save More

Only with dynamic control of cooling air can the amount of efficiency gains possible with a physical containment system be maximized. Though airflow containment enables a reduction in cooling, that reduction is limited by the lack of ability to closely and dynamically match demand and supply. Dynamic control can provide a significant increase in total system efficiency over cold aisle containment alone.

Balance Becomes More Important

Cooling demand is never static; it varies as servers ramp up and down and as equipment is installed and removed. The effects of variance in demand are amplified with cold aisle containment, as each aisle needs individual balancing of supply and demand.

Increased Visibility Needed

In order to control dynamically, temperature monitoring at the rack level is needed throughout the floor. This richer level of visibility also serves to reduce the risk associated with operating the environment at higher set points and closer to capacity thresholds.

Polargy’s Approach

Polargy will provide a customized solution that actively manages airflow in an efficient manner based on the site’s existing cooling architecture and the type of airflow containment. The scope of the solution is focused on monitoring inlet temperatures, dynamically controlling the CRAC units, controlling active floor fan panels if they are needed, and providing a web-based interface to give data center operators a visual display of the floor temperatures and cooling system. The real-time temperature data from the monitoring is used to control the cooling resources to dynamically match supply to demand. The use of floor fan panels gives a localized supply adjustment that deals with variance in demand so that overall supply doesn’t have to increase to address demand variance within the contained aisles.

We use a combination of standard protocols and communication interfaces that are provided with data center equipment, along with hardwired and wireless sensors for legacy equipment. One key benefit of this approach is that it is not a proprietary software/hardware package so there are no software licenses involved.
