A miniaturized air handler assembly provides an air handler that resides completely on a drain pan, and comprises multiple panels. At least two panels join at the edges to form an enclosed chamber with central region. Two of the opposing panels are apertured to enable passage of air. Multiple coils carrying cooling fluid are disposed in a parallel relationship, and on the inner side, of the coil panels. A blower forces high velocity air through one or more opposing coil panels, and across the coils to cool the air. All of the condensate that inherently forms on the coils falls into the drain pan. From the coils, cooled air flows to central region of air handler. A fan at the top of the air handler draws the cooled air from an outlet opening that forms in a top panel for dispersing through a duct or plenum.

An outdoor unit for an air-conditioning apparatus according to the present disclosure includes a heat exchanger comprised of an upper heat exchanger and a lower heat exchanger that are arranged in an up-down direction, an accumulator configured to store refrigerant, a casing, an inside of which is partitioned by a partition plate into an air-sending chamber accommodating the heat exchanger and a machine chamber accommodating the accumulator, and a fixing component configured to be fixed to the heat exchanger and the accumulator so that the accumulator is fixed to the heat exchanger, wherein the fixing component is fixed to both of the upper heat exchanger and the lower heat exchanger.

A heat exchanger placed in front of an air blower is appropriately supported by a cabinet. In an indoor unit, the heat exchanger is placed only in front of a rotation center of an air-blowing fan. The cabinet includes: an upper left protrusion and an upper right protrusion protruding forward from an upper portion of the cabinet; and a lower left protrusion and a lower right protrusion protruding forward from a lower portion of the cabinet, so that the protrusions support the heat exchanger.

An air conditioner is disclosed. The disclosed air conditioner can comprise: a housing having an inflow port and a discharge port; a partition disposed inside the housing so as to divide the inside of the housing into a first space at the inflow port side and a second space at the discharge port side, and having at least one opening for allowing the first space and the second space to communicate; at least one blower unit disposed in the first space, and including a duct, which passes through the opening so as to protrude toward the second space and discharges the air of the first space to the second space; and a heat exchanger disposed in the second space.
