Advances in the reliability and tolerance to environmental conditions of data center equipment have led many large-scale data centers to take full advantage of the outdoor ambient conditions to provide cooling for the servers and other critical network equipment to lower the PUEs for these facilities.

In early 2020, buildings around the world transitioned from full occupancy to low occupancy in a matter of days.

Underground cooling towers and controls with graphics custom-designed to complement the facility engineers’ operational expectations? These are just two aspects of the Moscone Center’s expansion strategy to stand out and stand up to unusual demands.

Modern data centers are evaluated not just on reliability but also on the efficiency of the cooling plant that supports them, so the cost to cool data center space is a key issue that must be addressed during design and system selection.

One of the most important factors in the efficiency of any HVAC system is the selection and implementation of the proper control sequence of operations. 

Carrier has released its newly designed variable air volume (VAV) WeatherExpert™ 48/50LC 6- to 23-ton packaged rooftop units. The newly designed WeatherExpert VAV models, available from 23 tons down to 6 tons, use a dedicated i-Vu® controller that links communication between the system zone terminals and the unit to efficiently adjust the air flow and compressor stages that are required.
