摘要： A heat source device includes a heat medium channel through which a heat medium flows, a plurality of refrigerant circuits through which refrigerant circulates, and a plurality of heat-medium heat exchangers configured to cause heat exchange to be performed between the heat medium in the heat medium channel and the refrigerant in the refrigerant circuits. The plurality of heat-medium heat exchangers include a first heat-medium heat exchanger to which at least one of the refrigerant circuits is connected and a second heat-medium heat exchanger to which a greater number of the refrigerant circuits are connected than to the first heat-medium heat exchanger.

摘要： A chilling unit includes a machine room unit to accommodate a compressor and a heat exchanger, and a plurality of air heat exchangers placed on top of the machine room unit. The air heat exchangers include a pair of air heat exchangers including two air heat exchangers opposite to each other in a lateral direction. They are inclined such that respective upper end portions of the two air heat exchangers have a spacing between each other greater than a spacing between respective lower end portions of the two air heat exchangers. In the lateral direction, the machine room unit has a top width greater than a heat-exchanger bottom width, the top width is one between side walls in a top face portion of the machine room unit, the bottom width is defined as a width between outer side faces of the respective lower end portions of the two air heat exchangers.
