<P>PROBLEM TO BE SOLVED: To attain miniaturization and simplification of an exhaust system in spite of having auxiliary heat exchangers in a one-can type composite heat source machine wherein a first combustion part 3-1 having a first burner 4-1 and a first main heat exchanger 5-1 thereon for hot water supply, and a second combustion part 3-2 having a second burner 4-2 and a second main heat exchanger 5-2 thereon for use other than hot water supply, are laterally juxtaposed in a state of being partitioned by a partition wall 2a in a single can 2, and latent heat recovery type first and second auxiliary heat exchangers 11-1, 11-2 are provided connected to the upstream side of the first and second main heat exchangers. <P>SOLUTION: The internal space of an exhaust hood 9 common to both combustion parts 3-1, 3-2 arranged on the can 2 is partitioned by a partition wall 9c into first and second exhaust spaces 10-1, 10-2 through which combustion exhaust of the first and second burners 4-1, 4-2 flows, and the first and second auxiliary heat exchangers 11-1, 11-2 composed of laterally meandering heat absorbing tubes 11a are arranged in the respective exhaust spaces. <P>COPYRIGHT: (C)2007,JPO&INPIT |
