Abstract: An induced air discharging unit includes: a jet flow generator configured to discharge supply air fed from outside, the jet flow generator discharging the supply air as a jet flow of air; an air inducer configured to allow air of an air-conditioning target space to be induced by an inducing effect of the jet flow of air discharged from the jet flow generator; an air mixer configured to discharge mixed air of the jet flow of air from the jet flow generator and the air induced by the air inducer to the air-conditioning target space, and radiate heat of the mixed air to the air-conditioning target space; and an air purifier configured to produce a purifying substance that purifies a purification target substance by chemical reaction, and blow out the purifying substance to the air-conditioning target space.

Abstract: An air-conditioning system includes an air conditioner, a heat source device, and a controller. In a case where an indoor temperature is a setting value, the controller performs a first adjustment operation including: transmitting a switching signal to the heat source device to instruct the heat source device to switch a setting water temperature to a first setting water temperature; and adjusting a temperature difference of heat-exchange water to a target water temperature difference. In a case where the indoor temperature is not the setting value, the controller performs a second adjustment operation including: transmitting a switching signal to the heat source device to instruct the heat source device to switch the setting water temperature to a second setting water temperature; and adjusting an air supply temperature of air-conditioning air to a setting air supply temperature.

Abstract: In an induction emission air conditioning apparatus installed in a ceiling, it is provided within a casing with a heat exchanger through which a feed air introduced from an outdoor side passes, a fan passing the feed air through the air conditioning heat exchanger, and a heating and cooling unit 1 for blowing a mixed air obtained by inducing and suctioning the air in the room inside by using the feed air passing through the heat exchanger so as to mix with the feed air, into the room inside in a laminar manner, and emitting the heat of the mixed air to the room inside, integrally.
