摘要： A heat source unit (3) for a refrigeration apparatus (1) includes a casing (50), a heat exchanger (60), and a propeller fan (70). The casing (50) has a back surface and one side surface each having an inlet (53), and a front surface having an outlet (52). A partition plate (51) defining an air passage (A) faces the one side surface of the casing (50). The heat exchanger (60) is provided along the inlet (53). A first distance S1 and a second distance S2 satisfies the relationship "6 ≤ S1/S2," where the first distance S1 is the shortest distance between an outer peripheral circle (V) of the propeller fan (70) and a second portion (62) of the heat exchanger (60), and the second distance S2 is the shortest distance between the outer peripheral circle (V) of the propeller fan (70) and the partition plate (51).

摘要： Provided is a propeller fan capable of improving performance. The propeller fan includes: a shaft portion that rotates about a center axial line; and a plurality of blades that have roots connected to an outer periphery of the shaft portion and extend in a radial direction, trailing edge side surface area increased regions (S2) and leading edge side surface area increased regions (S1) are included such that dimensions in an axial line direction parallel to the center axial line are larger on a side of tips than on a side of the roots in a case in which projection to a meridional plane including a blade center axial line is performed, and the trailing edge side surface area increased regions (S2) are larger than the leading edge side surface area increased regions (S1). A blade stagger angle with respect to a direction of the center axial line locally increases such that an amount of change from distribution that substantially linearly increases from the side of the roots toward the side of tips of the blades has a maximum value at a center position of a blade height with reference to the distribution.
