Select and prepare an installation site Heat vent kits 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. Required change in room 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.
