Abstract

An air conditioner provides an indoor unit (20) whose internal parts are optimally designed in dimensions and arrangement to satisfy prescribed relationships in order to actualize a noticeable reduction in noise without unwanted enlargement of dimensions. With respect to the distances L1 and L2 ranging from the tangential fan (25) to the stabilizer (26) and casing (28) respectively, the indoor unit is designed to satisfy at least one ofthe three relationships L1 < L2, 1.0s</=L1</=1.3s, and 1.2s</=L2</= 2.0s. With respect to the distance L between the tangential fan and its proximate indoor heat exchanger (23a), the relationship of 2.5d</=L</=3.5d is established. With respect to the distances L1 and L2 ranging from the tangential fan to the adjoining indoor heat exchangers (23a, 23b) respectively, the relationship of 1.5L1</=L2</=3.5L1 is established. <IMAGE>
