Provided is an air conditioner with which it is possible to prevent a decrease in heating performance by preventing drainage water, which has dripped down from an upper heat exchanger performing a defrost operation, from refreezing in a heat exchanger used in a heating operation. This air conditioner is equipped with: a heat-source-side heat exchanger (8), comprising multiple heat exchange units (17) which are arranged in parallel in the vertical direction and to which a refrigerant is supplied via mutually different paths; and a partial defrosting means that performs a defrosting operation on the other heat exchange units (17) when some of the heat exchange units (17) are used to perform heating. Water discharge mechanisms (37, 30f) that discharge the drainage water generated in the heat exchange units (17) are provided for each of the heat exchange units (17).
