Abstract
Provided is an air-conditioning apparatus having a low-outside-air-temperature cooling operation mode including: a refrigerant circuit; an outdoor fan; an outdoor air temperature sensor; an indoor heat exchanger intermediate temperature sensor; an indoor heat exchanger outlet temperature sensor; and a controller configured to, when a measured value from the outdoor air temperature sensor is equal to or less than a predetermined value, perform the low-outside-air-temperature cooling operation mode, wherein in the low-outside-air-temperature cooling operation mode, the controller is configured to reduce a rotation speed of the outdoor fan, and to, when a difference between a measured value from the indoor heat exchanger outlet temperature sensor and a measured value from the indoor heat exchanger intermediate temperature sensor is equal to or greater than a first threshold, increase an opening degree of the pressure reducing device.
