Ho Y Nam,
I'm not sure what you mean by the "two-channel method." But I am guessing that you are referring to the fact that forced-air heating systems have two separate duct systems: a supply system and a return system.
Briefly, here is how a forced-air heating system works. A furnace has a burner that heats air in a heat-exhanger. A fan distributes the hot air through a duct system. (That's the supply system. We call these ducts the "supply ducts.") And a return-air duct system pulls air from some of the rooms in the building and brings the air back to the furnace to be heated again.
I will attach some illustrations below.
