FIG. 3 , it is preferred that thespray nozzles discharge opening 58 of the respective indoor units C in accordance with implementation conditions, so that the steam is discharged along with air. - Also, opening/closing
valves spray nozzles - The
steam pipe 85 is provided with a flow rate control valve 95 to adjust the amount of steam to be injected via thespray nozzles - Hereinafter, the operation of the cooling/heating air conditioner with a humidifying function according to the present invention having the above configuration will be described.
- As shown in
FIG. 2 , when the cooling/heating air conditioner is operated in main cooling mode, two indoor units C are operated in cooling mode and the other indoor unit C3 is operated in heating mode. - In this case, the
indoor heat exchangers indoor heat exchangers condensed water sumps condensed water pipe 67, to be gathered in thesteam tank 65. Admittedly, when the condensed water is unable to naturally flow due to a height difference, thepump 68 is driven, so that the condensed water is stored in thesteam tank 65. - After a sufficient amount of the condensed water is gathered in the
steam tank 65, thesteam generating device 80 using theultrasonic vibrator 81 is operated to generate steam. Subsequently, the generated steam is supplied into a room, in which the heating-side indoor unit C3 is mounted, by way of thesteam pipe 85, thereby acting to humidify the room. - In this case, the opening/
closing valves - On the other hand, when the cooling/heating air conditioner is operated in full heating mode, i.e. when all the rooms are to be heated, all the
indoor heat exchangers outdoor heat exchanger 2 serves as an evaporator. Accordingly, the steam can be generated, in the same manner as stated above, by use of the condensed water produced by theoutdoor heat exchanger 2. Then, the steam is supplied into the rooms in which the heating-side indoor units C1, C2, and C3 are mounted, to humidify the rooms. - Meanwhile, when an insufficient amount of condensed water is supplied into the
steam tank 65, water is supplied from an external station to thesteam tank 65 by use of the externalwater supply device 70, to generate steam. Specifically, if thewater level sensor 74 provided in thesteam tank 65 generates a signal informing that the water level is below a predetermined value, the opening/closingvalve 73 is opened, so that the water stored in thewater storage tank 72 is supplied into thesteam tank 65, to be used for the generation of steam. - As is apparent from the above description, the present invention provides a cooling/heating air conditioner with a humidifying function, which is designed to generate steam by use of condensed water produced during cooling/heating operations and to supply the steam into a desired room in which a heating operation is carried out. Consequently, the present invention has the effect of realizing more pleasant air conditioning environment in a heated room that may be easily dried, and of achieving effective utilization of the condensed water.
- Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
