Abstract

See full text

An outdoor unit of an air-conditioning apparatus includes: a refrigerant circuit in which a compressor and an outdoor-side heat exchanger are connected by a refrigerant pipe; an outdoor-side fan that sends air to the outdoor-side heat exchanger; and a controller including an inverter circuit configured to drive the compressor. The controller includes: a first heat generating component; a second heat generating component that generates a smaller amount of heat than the first heat generating component; a temperature detection circuit provided in the first heat generating component to detect a temperature thereof; a temperature acquisition module that acquires the temperature detected by the temperature detection circuit; and an estimate calculation module that calculates a temperature estimate of the second heat generating component based on the temperature acquired by the temperature acquisition module, and calculates an estimate of a life of the second heat generating component based on the temperature estimate.
