C. DUCT WORK/AIR CONDITIONING/SUPPLY/RETURN AIRFLOW AND AIR
TEMPERATURE:
If the furnace is used in connection with summer air conditioning (cooling), the furnace should
be installed parallel with or on the upstream side of the evaporator coil to avoid condensation in
the furnace heat exchanger. If the cooling unit is installed with a parallel flow arrangement,
dampers or other means used to control flow of air should be provided to prevent chilled air from
entering the furnace. If such a damper is manually operated, it must be equipped with a means to
prevent operation of either unit, unless the damper is in the full heat or cool position.
The supply/return airflow shall be set to obtain an air temperature rise, across the furnace, in the
range of 55º to 85ºF. Since the flow resistance of each duct system is slightly different, the
airflow (fan speed) may have to be changed in the field to achieve a satisfactory temperature rise.
One way to measure the temperature rise across the furnace is to insert temperature measuring
devices (e.g. thermometers) into the return air duct and into the supply air duct about 12 inches
from the furnace. After the furnace has been firing continually for over 20 minutes, read the
temperature difference between the two (2) thermometers. The temperature difference should
not exceed 85ºF, nor be less than 55ºF. A temperature rise of 70ºF is considered to be optimum
for comfort.
The duct system should again follow the current design standard of Air Conditioning Contractors
of America (ACCA) or ASHRAE Fundamentals volume. The most common location for the A-
shaped coil (A style) is shown in Fig. 1.
