Heat Vent Kits; Required Change In Room Airflow - Xerox DocuTech 6100 Install Manual

Heat vent kits

Required change in room airflow

DocuTech 61xx Installation Planning Guide
If heat output for the DocuTech without the heat vent kits was
assumed, use the heat output value with the vent kits and
recalculate the Heat Management Worksheets. The combination
of vent kits and reserved capacity may be all that is required to
yield an acceptable change in room temperature. If not, the
facility may have to be upgraded to provide adequate cooling
capacity.
NOTE: Heat vent kits are available for the DocuTech printer.
When using the heat output values with the vent kits, remember
that a minimum airflow of 200 CFMs is assumed. At the time of
installation of a heat vent kit, it is recommended that the site
HVAC engineer or contractor verify the minimum airflow.
Estimate how much additional room airflow would be required to
maintain the present room temperature, thus offsetting the
additional heat load.
The amount of additional airflow depends on the difference
between the incoming air temperature and the present room
temperature, as well as the amount of added heat load.
To estimate this airflow requirement, refer to figure ___ and the
steps outlined below. The figure shows the estimated additional
room airflow that is needed in order to maintain present room
temperature conditions.
1. Subtract the incoming air temperature (worksheet step 1)
from the present maximum room temperature (worksheet
step 2).
2. In the figure, select the appropriate heat load (worksheet step
4 or 6), and refer to the temperature difference curve that
corresponds to the result in the above step 1.
3. Refer to the required additional room airflow.
If the incoming air temperature is 55° F (13° C), the required
room airflow (in CFM) can be expressed in terms of tons of
air conditioning by dividing the number by 450.
