Mist can be ejected to the entire bathroom 101.

  Moreover, the control valve unit 3C that controls the ejection of mist is provided as a single unit, and the cost of the mist generator 3 can be reduced by branching the piping and connecting a plurality of nozzle units.

<Modification of the air conditioning system of the present embodiment>
In the bathroom air-conditioning system 1A described above, one main bathroom air-conditioner 2A and one sub-bathroom air-conditioner 2B are installed, but a plurality of units are installed depending on conditions such as the floor area and ceiling height of the bathroom 101. Also good.

  Moreover, while installing the main bathroom air conditioner 2A above the washing place 101b, the sub bathroom air conditioner 2B may be installed above the bathtub 101a.

  Furthermore, the sub-bathroom air conditioner 2B is not diverted from a general bathroom heating ventilation dryer, but can be replaced by other heating equipment, for example, different types of heating equipment such as a panel heater and a bathroom floor heater. It is also possible to link with.

  On the other hand, the auxiliary bathroom air conditioner 2B may be provided with a ventilation function or an electric louver so as to have the same function as the main bathroom air conditioner 2A.

  Further, a control valve unit may be provided for each nozzle unit of the mist installed corresponding to each air conditioner so that the position where the mist is ejected can be switched.

  Furthermore, a human sensor is provided to detect the location of the bather or the like in the bathroom 101, and the operation of the electric louver is controlled so that the wind and mist hit the person in a spot manner, or the wind and mist do not hit the person. You may control to.
