    • A ceiling embedded type or ceiling suspension type air conditioner employing a cross−fin type heat exchanger in which the effective length of the heat exchanger is increased without increasing the casing size of an indoor unit. The indoor unit (1) comprises a casing (11) for holding the components of the indoor unit (1) and having an air inlet (20) and an air outlet (21), a centrifugal fan (17) disposed in the casing (11) and blowing out air sucked from the air inlet (20) sideways, and a cross−fin type heat exchanger (27) disposed to surround the centrifugal fan (17) in order to exchange heat with air blown out from the centrifugal fan (17). The heat exchanger (27) has a plurality of recesses (28) formed to approach the outer circumferential part of the centrifugal fan (17), and a plurality of protrusions (29) formed to recede from the outer circumferential part of the centrifugal fan (17).
    • 一种使用交叉翅片式热交换器的天花板嵌入型或天花板悬挂式空调器,其中,在不增加室内机的外壳尺寸的情况下,增加热交换器的有效长度。 室内机1包括用于保持室内单元1的部件并具有空气入口20和空气出口21的壳体11,设置在壳体内的离心风扇17, 11),并且从空气入口(20)侧面吸出的空气吹出,并且设置成围绕离心式风扇(17)设置的交叉翅片式热交换器(27),以便与从离心式风扇吹出的空气进行热交换 17)。 热交换器(27)具有形成为与离心式风扇(17)的外周部接近的多个凹部(28),并且形成为从离心式风扇的外周部分后退的多个突起(29) 17)。
