The article undertook an analysis to the characteristic that system of canal of air conditioning wind uses in the center of family expenses above all, be in charge of to two kinds of commonly used wind next -- canal of wind of galvanization iron sheet and compound wind canal undertook technology and economy are compared, the compound wind canal that points out with wind of aluminum foil of phenolic aldehyde bubble the canal is a delegate has clear advantage. Finally, manage type housekeeping money according to multinomial wind the actual installation experience of project of central air conditioning, summed up a few family expenses the item that wind of central air conditioning should notice in tubal construction.
