Frequently Asked Questions

Failing CFDS

My data center project has a falling external CFD. Can Peak+ help address it?

Yes. This is a common use-case for Peak+ systems. Failing external CFDs from heat island and microclimate dynamics from hot air recirculation in dense chiller yards and hot exhaust air from nearby generators is increasingly a significant problem for data centers.

Our adiabatic pre-cooling systems have proven to be an effective approach to solving failing CFDS by enabling air-cooled chillers to operate at their design temperatures.

Making the Most of Your Megawatts

How can a Peak+ system help generate more revenue from the fixed power available at a data center?

Peak+ systems can meaningfully reduce a facilities' Peak PUE (PPUE), which typically occurs during the hottest times of the year. By precisely pre-cooling the condenser entering air temperature of air-cooled equipment, Peak+ reduces the power demand of that equipment, which frees up power to instead be used for incremental critical IT load. Since critical IT load power is the key determinant of a data center's potential revenue, precisely and reliably reducing PPUE can enable significant incremental revenue opportunities.

Peak-Shaving Use Cases

How can a Peak+ system reduce peak power demand? What are some of the benefits of peak-shaving?

Peak-shaving (reducing a facility’s peak total power demand) by using adiabatic precooling to reduce the power required by the compressors of air-cooled chillers is a common and compelling use-case of our systems. Peak facility power demand is driven by high ambient temperatures -- those hot days and weeks in the summer when the compressors on air conditioners and industrial chillers must work very hard to compress refrigerant so that heat can be rejected from the units' condenser coils. The higher the ambient air temperature reaching the condenser coils of an air-cooled chiller, the greater the power needed for the compressor, and the greater the strain on the power grid. It is common to see projects with projected condenser entering air temperatures above the cooling equipment’s design temperatures, which can cause significant derate of unit performance and capacity, and in some cases could result in chiller shutdown from excessive head pressures.

By pre-cooling the condenser entering air temperature with a Peak+ adiabatic precooling system, the air-cooled chiller’s compressor workload is reduced, which means power needed for cooling is reduced, which frees up power for  other uses at the facility (such for incremental critical IT load at a data center).

Peak-shaving via Peak+ adiabatic cooling is a way to turn a previously unmanageable variable -- condenser entering air temperature -- into a manageable parameter. But precise control is essential.

In cases where a facility owner using Peak+ prefers to save on CAPEX rather than use the freed-up peak-shaved power for other uses, then the owner is able to pursue reduced CAPEX investment scenarios for the facility's primary and backup power infrastructure.

Addressing Derate of Performance of OEM Chiller Equipment

How does a Peak+ system help address derated performance of heat rejection and cooling equipment?

Cooling equipment performance derate can be a significant issue for design engineers, chiller OEMs, and project owners, especially for chiller yards with hot air recirculation that exceeds equipment design temperatures.

As condenser entering air temperature increases, chiller performance (such as kwh required per ton of cooling) and cooling capacity (tons) can degrade, especially when ambient temperatures exceed a chiller's design temperature.

Peak+ systems pre-cool and suppress the condenser entering air temperature, enabling the chiller equipment to perform as designed and avoid derated chiller performance.
