HEAT SOURCE DEVICE, HEAT EXCHANGE METHOD AND HEAT EXCHANGER

摘要

PROBLEM TO BE SOLVED: To stabilize hot water supply characteristics and simplify a circuit for heating medium circulation.SOLUTION: A heat source device includes: a heat source (4); a first circulation passage (8-1) for circulating a heating medium (M); a second circulation passage (8-2) for circulating bathtub water (BW); a first heat exchanger (6-1) having a heating medium heat exchange section (6-11) for exchanging heat between the heat source and the heating medium and a bathtub water heat exchange section (6-12) for exchanging heat between the heat source and the bathtub water; and a second heat exchanger (6-2) for exchanging heat between the heating medium heated by the heating medium heat exchange section (6-11) and supplied water to deliver hot water.SELECTED DRAWING: Figure 1
