Abstract

Provided is an air conditioner with which the occurrence of condensation when cooling a controller can be eliminated by a refrigerant pipe. Even if condensation or frost formation occurs, malfunctioning of the controller, damage to electronic components due to drain liquid can be prevented. The refrigerant pipe is placed in close contact with the controller. In an air conditioner (1) provided with a refrigeration cycle (11) and a controller (12) that is cooled during cooling operation by being in contact with a refrigerant pipe (10A) in which low-pressure two-phase refrigerant flows, a condensation-prevention control portion (24) is provided which, when a condition for condensation to occur on the refrigerant pipe (10A) is detected, the condensation is prevented by any one of rotational-speed control of an indoor fan (7), rotational-speed control of an outdoor fan (4), degree-of-opening control of an electronic expansion valve (6), and rotational-speed control of a compressor (2).
