Temperature Control VAV Damper

Description

ZTFLOOR underfloor temperature control VAV damper is used to Provide sufficient air to accommodate the peal energy demands of the rack.resulting in wasted bypass air and over-cooling during all less than peal conditions. The damper measures the incoming air temperatures at the face of the rack and adjusts the VAV damper to control the air flow and ensure thet the temperature at the face of the rack is never above the maximum allowable set point provided by the user.

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 Achiving 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 idel states a diverse environment.

Fuhua’s VAV damper electronically controlled variable air volime damper used in conjuction 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.

Air Flow System

Product Overview

Quite different from other air-supply racks, Fuhua oriented ventilation plate can Supply the wind directly to server cabinet by adjusting the angels of airflow, to Ensure the whole directions blowing rate, instead of blowing against the server.

Main performances

Easy-cooling cabinet with large capacity:
It has bigger opening area and larger airflow. What’s more, the guide vane can supply airflow through the server cabinet, covering 93% of the whole interspace. It means 93% airflow from the rack can get into the server cabinet to offer the best cooling service. For normal ventilating board, it can only supply 30-50% of them through into the cabinet. This improvement makes it possible for oriented ventilation plate to effectively provide more than 25KW’S refrigerating effects to every server cabinet.

Solid, artistic and duable:
1072kg rolling load, 1134kg designed load with the minimum safety factor of 2.0, the equipments can be moved on the airflow rack, without worrying about the rack strength. The attached insulating outer layer makes it nicer and most importantly, it’s anti-static.

Improve the financial performance of data center:
To a largest degree, oriented ventilation place can improve the financial performance of new build or existing data center and reduce the number of air-conditioning equipments in a room. In a room. In order to save energy, reconstruction project sets speed fan in standby mode or adjust the speed fan to run in the low and statuc pressure condition. As the same level, 93% of the air capture efficiency that makes the equipments overall cooling capacity greatly improved, however, 40% of the cooling facilities investment reduced.

No isolation by cold and hot channel clapboard is needed:
The cold and hot channel isolation is not only bad for fireproof, but also inconvenient to layout equipments. Different from the oriented ventilation plate will stay against the ensure its cooling effect, which will be much better than diaphragm isolation.

Brushed Grommet

These series have solved the air-condition optimization and the energy saving issues in computer rooms immediately after it was put into markets. What’s more, it reduces the waste of airflow in the data center, lessens the power fare and lengthens rhe instruments service time. It’s energy saving and beautiful to look at.

Characteristics

• It is firmly combined with the raised flooring.
• It’s 32-square-inch cabling covering can satisfy different cabling requirements, including 100 Ampere power connector.
• This product accords with the relative rules of NFPA in Section 75, part 5-4.4.
• Such products has no components easy to loose.
• According with relative EU ROHS rules on limits for harmful substance.

Scope of installation

It should be pre-installed at the designed cabling holes before installing the floors and cabling.

Benefits after installation

• Sealed cabling holes to blocks-up the blas flow.
• Improve the cooling efficiency of air conditioners.
• Increase the amount of instruments in the data center.
• Increase the pressure of plenum chamber under the floor, to ensure the cooling airflow can be sent further.
• Increase the air volume of from the air exhausting floor.
• Reduce the humidity and control the cost.
• The data center should be layoutted with hot channels with hot channels and cooling channels and cooling channels, and it goes with it.
• Reduce the cost for using more air conditioners.

In-floor Velocity Adjustor

ZT velocity adjustor is made by sandel fire fighting fabric and widely used in data center. This completely non-flammable cover ensures that the in-floor air velocity adjustor is completely sate to use in a supply plenum.

Velocity adjustor is designed to diffuse subfloor air and eliminate under floor air bypass. This simple scientific solution will balance subfloor pressure, which enables air supply at any place in the data center.
