Temperature Control VAV Damper

1.Functions:
The data center is in constant flux. Load diversity between racks and variable server loads are the norm. Managing airflow into the data center space is key to achieving reliability. New demands to reduce energy consumption in the green data center require a fine balance to ensure proper air flow to each rack during peak IT hardware operation, while not cover-cooling partial load and idle states a diverse environment.
Fuhua's VAV damper electronically controlled variable air volume damper used in conjunction with power fan adjusts the amount of air to meet the specific needs of the rack it services. This flexibility can help effectively cool facilities implementing virtualization, cloud computing and idle server shutdown strategies with saving energy.
