Project Overview

Heapy performed a cooling system evaluation and report detailing the recommended modifications to the Verizon Wireless East Syracuse MSC. This facility evaluation included one network equipment room where HVAC performance and air flows were measured. The power being consumed on BDFBs, LDFBs, and other power centers were recorded at the same time. This allowed recommendations of changes to be presented based on this data for CRAC operation and air flow distribution throughout the space.

The assessment included:
Metering temperatures and air flows from individual air devices and racks measured over the course of time
Building Automation System (BAS) trending is utilized to evaluate equipment staging and operation over time.
Local power readings from local breakers including power being produced in the DC plant.
Room layout and rack layout is overlaid on a drawing with duct airflows and power distribution across the switch room. This allows all personnel to see where hot spots or air flow anomalies are located within the space.
Proper airflow recommendations for the current load is then provided often resulting in fewer CRACs operating than before with air flowing to the most power dense locations.
Recommendation of HVAC system upgrades to control cold
Wrote new sequence of controls for BAS and CRAC units for more efficient operation
Follow-up is then performed to see if recommendations were implemented correctly after the mechanical and controls contractor have made adjustments and installations.
Hired 3rd party air balance contractor and provided oversight during the final air balance to ensure correct adjustments were made.
Additional observations made to enhance space for future use
Worked with Verizon Network engineers on future planning for size and location of network equipment
