Calculate The Change In Heat Load; Calculate The Change In Room Temperature - Xerox DocuTech 6100 Install Manual

Calculate the change in heat load

4. Heat output from the system in run mode in BTU per hr.
NOTE: Identify the appropriate heat output for the system from the table
Heat dissipation for the DocuTech printers and devices.
5. Heat output, in run mode, of the system that is to be removed.
NOTE: The table Copier heat output lists the heat output for a number of
copiers. If no system is being removed, enter zero (0) and proceed to step 8,
using the BTU per hr from step 4.
6. Calculate the change in heat load to the room. Subtract the system heat
output in step 5 from the heat output in step 4.
NOTE: If this number is less than 2000 BTU per hr, no additional heat
management actions should be required. If this number is 2000 BTU per hr or
more, proceed to step 7.

Calculate the change in room temperature

7a. Take the change in heat load from step 6 and refer to the figure
"Room temperature change" to determine the change in room
temperature when the DocuTech is substituted for a currently
operating system. If the value from step 6 exceeds 16,000 BTU per
hr, refer to the figure "Room temperature change (system replaced)".
The figures are used to locate the appropriate change in room BTU
per hr. Refer to the appropriate room airflow rate. Then, review the
change that can be expected.
7b. Take the maximum room temperature in step 2 and add the
change in room temperature from 7a. Compare the result with the
maximum acceptable room temperature from step 3.
NOTE: If this temperature change causes the room temperature to
exceed the maximum acceptable room temperature, refer to the heat
management alternatives.
DocuTech 61xx Installation Planning Guide
Use the following table to calculate the change in heat load to
the room. Proceed to the next section to calculate the resulting
change in room temperature.
Table 4-9. Calculating the heat load
Use the following table to calculate the change in room
temperature.
• Use step 7 if the DocuTech is replacing a currently operating
system.
• Use step 8 if the DocuTech is a new addition to the room.
