Claim 2:
3. A system for air-conditioning and hot-water supply configured to alternatively perform a cooling operation and a heating operation, comprising:
an outdoor unit having a compressor and an outdoor heat exchanger;
a plurality of indoor units each of which is connected to the outdoor unit and includes an indoor heat exchanger, each indoor unit being configured to control a room temperature;
a hot-water supply unit connected to the outdoor unit so as to be arranged in parallel to the plurality of indoor units and including a refrigerant-water heat exchanger; and
a controller configured to monitor an occurrence of a hot-water request for hot-water supply from the hot-water supply unit during the cooling operation performed at at least one of the plurality of indoor units, and then to stop the cooling operation performed at the at least one of the plurality of indoor units and to start the heating operation in accordance with the hot-water request;
wherein
the controller is further configured to monitor an occurrence of an indoor-unit request from any one of the plurality of indoor units; and
the controller is further configured to stop the heating operation and to resume said cooling operation where said indoor-unit request is an increase request for an increase of load of said cooling operation to reduce the room temperature, and
wherein
the controller is further configured to determine that the increase request has occurred where said request occurred during said indoor-unit heating operation is a request for an increase of amount of wind from an indoor unit which was in said cooling operation prior to the start of said heating operation, the indoor unit configured to blow the wind into a space where the indoor unit is provided.
