A floor-standing air-conditioning apparatus comprising: a lower air inlet having an air inlet opening configured to allow air to flow into a body from a lower portion of the body on a side of a front face (1 a) of the body; an air outlet having an air outlet opening configured to allow air in the body to flow out of the body and rise; a heat exchanger that is provided in the body and configured to condition air; a crossflow fan that is provided in the body and configured to produce a flow of air in which the air that has flowed into the body passes through the heat exchanger and is guided to the air outlet; a drain pan that is provided below the heat exchanger in a height direction of the body and configured to receive water generated by dew condensation; a lower diffuser provided in a lower portion of the air outlet in the body so as not to be oriented toward the air outlet; and a front air inlet provided in a front panel configured to cover the front face of the body and provided between the lower air inlet and the air outlet, the front air inlet including an opening configured to allow air to flow into the body, wherein the crossflow fan is provided on a side of rear face with respect to a center of the body in a depth direction, the heat exchanger includes a front heat exchanger provided on the side of the front face and a rear heat exchanger provided on the side of rear face, the pair of which form a V shape with their lower ends being in contact with or in proximity to each other, and are arranged so that the crossflow fan is positioned between the front heat exchanger and the rear heat exchanger, the apparatus is configured such that the air having flown therein from the lower air inlet is split into a front air passage provided on a front side with respect to a drain-pan front side wall (11 b) of the drain pan and forming a passage of air flowing into the front heat exchanger, and a rear air passage provided on a rear side with respect to a drain-pan rear side wall of the drain pan and forming a passage of air flowing into the rear heat exchanger in the body, a shortest distance between the drain-pan front side wall and a front air passage wall surface of the body is larger than a shortest distance between the drain-pan rear side wall (11 c) and a rear air passage wall surface of the body, and the opening of the front air inlet is positioned in the height direction of the body to fall within a range between an upper end and a lower end of a circle defining a perimeter of the crossflow fan, characterized in that the crossflow fan is provided at a position below the air outlet in the height direction of the body and in that the lower diffuser has a recess at an end on a downstream side in a direction in which the air flows. a lower air inlet having an air inlet opening configured to allow air to flow into a body from a lower portion of the body on a side of a front face (1 a) of the body;
