Abstract (en)
[origin: US2020408459A1] An air-conditioning apparatus includes a heat exchanger, a fan, and a controller. The heat exchanger causes heat exchange to be performed between a medium that transfers heat, and air. The fan sends air to the heat exchanger. The controller determines whether clogging due to foreign matter has occurred in the heat exchanger, based on a command voltage varying in accordance with the rotation speed of a fan motor that drives the fan.
