Abstract (en)
[origin: EP3508795A1] An air-conditioning apparatus (101) includes a refrigerant circuit (102), a pipe temperature sensor (111), an indoor air blower (113), an air-conditioning load sensor device (125), and a controller (130). The pipe temperature sensor (111) senses a condensing temperature (CT). The indoor air blower (113) regulates a volume of air sent to an indoor heat exchanger (115). The air-conditioning load sensor device (125) senses air-conditioning load. The controller (130) has a first mode and a second mode different from the first mode as operation modes, and controls a volume of air sent by the indoor air blower (113). In the second mode, the controller (130) has the indoor air blower (113) operate such that a volume of air is varied between a first volume of air and a second volume of air larger than the first volume of air with variation in condensing temperature. When air-conditioning load sensed by the air-conditioning load sensor device (125) becomes lower than a first threshold value in the first mode, the controller (130) changes the first mode to the second mode.
