HVAC Considerations For the TX9000 and TX9200
HVAC Considerations For the TX9200
Planning the cooling for a TX9200 TelePresence room is important to ensure the room remains
comfortable for people in it and to protect the equipment by maintaining normal operating temperatures.
Caution
HVAC considerations should be given from the initial phase of choosing a room. Installing new cooling
(or heating) systems can be time-consuming.
The table summarizes the specific BTU output of a TX9200 when deployed as recommended and under
typical operating conditions. Please provide this information to your building HVAC engineer.
The qualifier
typically
assumes:
•
The system is not used constantly 24 hours a day, seven days a week, every week.
•
Deployment follows Cisco recommendations.
•
The room is located within a building interior.
•
The room has proper air circulation.
•
The room’s walls are painted with colors that are based on the TX9000 and TX9200 color palette.
For more information, refer to the
Cisco TelePresence Wall Color Guide

.
•
The target room temperature expected is 72-76 degrees F.
•
From these guidelines and for typical usage, a diversity factor of 25 percent is assumed which lowers
cooling requirements.
Note
Conditions not consistent with the above may require additional cooling. Consult with your HVAC
engineer to define building envelope and unique requirements. Additional equipment such as data
displays, document cameras, etc., require additional cooling.
