Abstract:
Provided is an efficient heat exchanger. In a heat-source heat exchanger (50), a plurality of refrigerant flowpaths (P) that extend in the vertical direction are disposed in the left-right direction which intersects the vertical direction, and a plurality of the refrigerant flowpaths are disposed in a front-rear direction which intersects the vertical direction and the left-right direction. The heat-source heat exchanger comprises a plurality of heat transfer tubes (60) that form the refrigerant flowpaths (P).
