A railway vehicle air-conditioning apparatus (100) is equipped with: an indoor heat exchanger (10) that evaporates a refrigerant; a cooperative device group (20) that forms, together with the indoor heat exchanger, a refrigeration cycle using the refrigerant by exchange of the refrigerant with the indoor heat exchanger; a waste heat recovery unit (80) that has a waste heat recovery part (81) that recovers waste heat from a waste heat source (WS) and a heat-release part (82) that releases, to an indoor heat exchanger, heat transmitted to the heat-release part, and that is switchable between (a) a heat-releasing state in which the waste heat recovered by the waste heat recovery part is transmitted to the heat-release part and released by the heat-release part, and (b) a heat-release-stopped state in which the waste heat recovered by the waste heat recovery part is less transmittable than when in the heat-releasing state; and a controller (90) to (i) control the waste heat recovery unit to be in a heat-release-stopped state when the refrigerant is being exchanged between the indoor heat exchanger and the cooperative device group, and (ii) control the waste heat recovery unit to be in a heat-releasing state when the exchange of the refrigerant is stopped.
