Temperature Rise Heat Pump Only Method

Temperature Rise Heat Pump Only Method
The Temperature Rise Resistive Heat Method can be used to
determine the heating capacity of the heat pump system in
the heat pump "only" mode. The results obtained using this
method should agree within 10% of the data published in the
Specification Sheets for the combination of indoor and outdoor
section.
NOTE: When using the following procedure to determine the
system's capacity, make sure that the indoor section's backup
heat source is de-energized.
1. Use the same procedure described in the Temperature
Rise Resistive Heat Method to determine the system's
CFM and temperature rise across the indoor section.
2. Determine the BTU output of the system for the measured
Temperature Rise and system CFM by using the following
formula
