The four types of gas furnace airflow patterns are _______, ______, _____, and______.
Four types of furnace airflow patterns.
Explanation of Solution
Gas furnaces have heat producing devices and its distribution system. The heat producing devices are burners, manifold and controls, venting system and heat exchanger. Distribution system contains blower that moves the air throughout the ductwork assembly. There are four types of airflow patterns which are given below:
UPFLOW
It is a vertical type of furnace with headroom. Cool air passes at the bottom or the sides of the bottom of the furnace. It releases hot air out the top of the furnace.
LOW BOY
It is also vertical type of furnace of approximately 4 ft with low headroom. Air intake and output are both at the top of the furnace.
DOWNFLOW
It is a type of counterflow furnace. The ductwork is in the concrete slab. Inlet of air is at top and output is at bottom.
HORIZONTAL
It is positioned on its side. Air inlet is at one end and output is at another end.
MULTIPOISE OR MULTIPOSITIONAL
It can be installed at any positioned. The flow can be downflow, up-flow, horizontal, etc.
