The cover is covered on the shell and the water storage tank, the cover is provided with a spray port communicated with the mist channel and a water inlet communicated with the water storage tank, the mist and the volatilizing essential oil float through the mist channel and the spray port to humidify air.

A method of maintaining a desired level of an aerosolized compound within a space to be treated with the compound, the method including providing a diffusion device with the compound in liquid form and a control system for operating the device. The control system includes a sensor in fluid communication with the air within the space to be treated configured to sense the concentration of the compound aerosolized within the space. The diffusion device is operated to diffuse the compound into the space. The concentration of the compound within the space to be treated is sensed with the sensor and operation of the diffusion device is altered based on the concentration of the compound sensed to achieve a desired concentration of compound within the space. The sensing and operation altering steps are repeated periodically to maintain the desired concentration of the compound within the space.

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.

An air conditioner is provided that may include a main body having an air inlet and an air outlet defined therein; a filter received in the main body to filter air suctioned into the main body; a heat exchanger configured to perform a heat exchange between a refrigerant and the air suctioned into the main body; and an ultraviolet (UV) sterilization module configured to sterilize the air suctioned into the main body. The UV sterilization module may include a porous main body in a mesh form, and a plurality of UV lamps. The porous main body may include a bent portion to allow the porous main body to conform to a shape of the heat exchanger.
