Air-conditioning apparatus

摘要

An air-conditioning apparatus (100 (200)) capable of air-conditioning operation and provided with a drain pan (9) that collects condensed water (13) caused in a heat exchanger as drain water (12) includes: a drain pump (10) drains the drain water (12) collected in the drain pan (9); and a controller (60 (201)) controls the drain pump (10), compares a rotation speed (current value to be supplied) of the drain pump (10) with a preset reference value of rotation speed (V) (reference value of current (I)), and determines the presence or absence of a sign of drain failure of the drain pump (10) on the basis of the result of the comparison.
