<P>PROBLEM TO BE SOLVED: To provide a double can type complex heat source machine provided with a first can body 2-1 and a second can body 2-2 and provided with a first auxiliary heat exchanger 11-1 of latent heat recovery type connected with the upstream side in the direction of water passing of a first main heat exchanger 4-1 provided in the first can body and a second auxiliary heat exchanger 11-2 of latent heat recovery type connected with the upstream side in the direction of water passing of a second main heat exchanger 4-2 provided in the second can body to reduce cost by using an exhaust case for both auxiliary heat exchangers in common and improve thermal efficiency by utilizing a space effectively. <P>SOLUTION: The single laterally long exhaust case 8 over both of the first can body 2-1 and the second can body 2-2 is arranged above the first and second can bodies, and the space in the exhaust case is partitioned into a first exhaust space 9-1 on one side in the horizontal direction and a second exhaust space 9-2 on the other side in the horizontal direction by a partitioning wall 8a. A plurality of heat absorbing meandering pipes 11a are stored in each exhaust space 9-1, 9-2 to constitute each of the first and second auxiliary heat exchangers 11-1, 11-2 by these heat absorbing pipes 11a. <P>COPYRIGHT: (C)2007,JPO&INPIT |
