摘要： A heat source system (3) supplies a heat medium to an AHU (2). The heat source system (3) comprises: a plurality of heat source units; and a system controller that controls, in accordance with a requested-capacity requested by the AHU, the number of the plurality of heat source units to run. If it is necessary to start a plurality of the heat source units in order to meet the requested-capacity requested by the AHU (2), the system controller causes the heat source units to start in stages, until the number of heat source units that were started reaches a necessary number of units determined on the basis of the requested capacity.

摘要： This fin comprises a plate-shaped substrate part (10) having a heat transfer tube passing part, which is a circular shape centered on a central axis C and through which a heat transfer tube passes, and a louver part at which a first slit is formed by a first louver (21). The louver part has a flat section (16), the first louver (21) that is provided on the downstream side of the flat section (16) and protrudes more in the Z-axis direction than the flat section (16), and a second louver (22) that is provided on the downstream side of the first louver (21). The second louver (22) has a linear part (22b) at which the shape of the cross-section thereof when cut in the XZ plane is linear, a second louver upstream part (22a) bending obliquely in the upstream direction from the upstream end of the linear part (22b) and extending linearly, and a second louver downstream part (22c) bending obliquely in the downstream direction from the downstream end of the linear part (22b) and extending linearly. The linear part (22b) is disposed so as to overlap with the heat transfer tube passing part when viewing the cross-section.
