    摘要: A hot water supply system includes a hot water supply apparatus, a plurality of supply paths, and an estimation unit. The hot water supply apparatus includes a heating apparatus configured to heat water, a tank configured to store the water heated by the heating apparatus, and a water circuit configured to circulate the water in the tank. Each supply path is coupled to a corresponding one of a plurality of hot water supply targets and is configured to supply the water from the tank. The estimation unit is configured to predict a total amount of hot water supply demand, based on time-series data of a first index that indicates an amount of heat of water used in each of the plurality of hot water supply targets.

    摘要: A ventilation device to be installed outdoors, includes: a casing; a heat exchanger accommodated in the casing and configured to perform heat exchange between outdoor air flowing indoors and indoor air flowing outdoors; an electric component unit including a control board and accommodated in the casing; and a fastener fixing, to the casing, an electric wire connected to the electric component unit. The heat exchanger is extractable sideward from the casing. The electric component unit is disposed above a projection region of the heat exchanger extracted from the casing. The casing includes a lead-out port disposed below the projection region and through which the electric wire is led out of the casing. The fastener is disposed between the electric component unit and the lead-out port. The electric wire fixed by the fastener is routed around the projection region.

    摘要: An air conditioner includes: a heat exchanger that exchanges heat between air sent to an air conditioning target space and a flammable refrigerant; a fan that generates an air flow in the heat exchanger; one of a heater that heats the air sent to the air conditioning target space, or an electric apparatus that is capable of causing electric discharge; a casing that has an arrangement space in which the heat exchanger, the fan, and the heater or the electric apparatus is disposed, and an opening that communicates the arrangement space with outdoors; and an opening and closing part that opens and closes the opening. The opening and closing part: closes the opening in response to the fan being driven, and opens the opening in response to the fan being stopped.
