`
`The present invention relates to an air conditioning system.
`
`Description of the Related Art
`
`An air conditioner is an apparatus for drawing indoor air into its main body to cool, heat,
`
`filter, or dehumidify the air and then discharge the air to the indoor space.
`
`Generally, there are two kinds of air conditioning system in the prior arts. Fig. 1 and Fig.
`
`2 are respectively schematic Views of these two kinds of air conditioning system.
`
`Fig. 1 shows a kind of air conditioning system in the prior arts. As shown in Fig. 1,
`
`small-size air conditioners 1, 2, 3 are respectively mounted in a sitting room 20, two bed rooms
`
`10 and have powers respectively corresponding to the areas of the sitting room 20 and the two
`
`bed rooms 10. Because there are air conditioners 2, 3 mounted in the bed rooms 10 and when
`
`the air conditioners 2, 3 are operated, they will generate noises and interfere with a user when
`
`the user takes a rest in the bed rooms 10. In addition, for each of the air conditioners 1,2, and 3,
`
`it needs to mount an indoor machine and an outdoor machine, which not only occupies outdoor
`
`space, but also has a high mounting cost and large man-hours. Also, the total energy
`
`consumption of the air conditionersl, 2, and 3 is high.
`
`Fig. ZShows another kind of air conditioning system in the prior arts. As shown in Fig. 2,
`
`a large-size air conditioner 4 is mounted in a sitting room 20 and has a power corresponding to
`
`the total area of the sitting room 20 and two bed rooms 10, and air exiting parts 5 are
`
`respectively mounted in the sitting room 20 and the two bed rooms 10. The large-size air
`
`conditioner 4 and the air exiting parts 5 are connected through ducts 6. The air in the sitting
`
`room 20 is sucked by the large-size air conditioner 4 and then discharged to the rooms from the
`1
`
`

`

`F1 140396
`
`air exiting parts 5 in the sitting room 20 and the two bed rooms 10 through the ducts 6. With the
`
`air conditioning system of Fig. 2, the large—size air conditioner 4 mounted in the sitting room 20
`
`must have a larger power and thus its power consumption is high.

`
`DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE IVENTION
`
`Exemplary embodiments of the present disclosure will be described hereinafter in detail-
`
`with reference to the attached drawings, wherein the like reference numerals refer to the like
`
`10
`
`elements. The present disclosure may, however, be embodied in many different forms and
`
`should not be construed as being limited to the embodiment set forth herein; rather, these
`
`embodiments are provided so that the present disclosure will be thorough and complete, and
`
`will fully convey the concept of the disclosure to those skilled in the art.
`

`
`First Embodiment
`
`Fig. 3 is a schematic View of an air conditioning system according to a first embodiment of
`
`the present invention. A dwelling house is taken as an example of the first embodiment. The
`
`dwelling house has a main room such as a sitting room, a sub-room such as a bed room, a
`
`reading room or a kitchen or other room. For the sake of description, Fig. 3 shows two bed
`
`rooms. However, the number of the bed rooms is not limited. There may be one or more bed
`rooms.
`
`As shown in Fig. 3, a sitting room 110 is provided with an air conditioner 140 and air
`
`ventilating devices 150; two bed rooms 120 each communicates with the sitting room 110 by
`
`the respective air ventilating devices 150 mounted in the sitting room 110. The air ventilating
`
`devices 150 discharge the air in the sitting room 110 to the bed rooms 120 communicated with
`
`the sitting room 110.
`
`With the above configuration, the air having been conditioned by the air conditioner 140 in
`
`the sitting room 110, such as cold air after cooling, is not discharged to the sitting room 110 and
`
`the respective bed rooms 120 through the ducts as in the prior arts, but is directly discharged
`
`only to the sitting room 110. Therefore, the air conditioner 140 in the sitting room 110 can have
`
`a power simply corresponding to the area of the sitting room 110. The cold air, after discharged
`
`to the sitting room 110, is sucked by the air ventilating device 150 in the sitting room 110 and is
`
`then discharged to the bed rooms 120. As a result, the cold air enters the bed rooms 120. In this
`
`way, even there is no air conditioner 140 in the bed rooms 120, cooling effect can be obtained
`
`in the bed rooms 120. Therefore, the space and the working hours for mounting the air
`
`conditioners 140 can be saved, the electricity power consumption can be reduced and the
`3
`
`20
`
`25
`
`3O
`
`35
`
`

`

`Fl 1 40396
`
`energy can be saved.
`
`The ventilating device 150 may be‘a ceiling-embedded ventilating fan mounted between
`
`the ceiling and the top of the room. Each of the bed room 120 is provided with an air exiting
`
`part 160. The ceiling—embedded ventilating fans are respectively connected to the air exiting
`
`parts 160 in the bed rooms 120 through ducts 170.
`
`With the above configuration, under the effect of the air conditioner 140, the cold air, after
`
`discharged to the sitting room 110, is sucked by the ceiling-embedded ventilating fans
`
`in the
`
`sitting room 110, and then flows to the respective air exiting parts 160 in the bed rooms 120
`
`through the ducts 170 and is discharged to the bed rooms 120. Because there is no fan motor in
`
`the air exiting parts 160 in the bed rooms 120, there will be no noise generated by the running
`
`of the fan motor, the users in the bed rooms 120 can be provided with a quiet environment.
`
`> In the embodiment, the‘number of the air ventilating devices 150 is the same as the number
`
`of the bed rooms 120. That is, there is a one—to-one correspondence relation between the air
`
`ventilating devices 150 and the bed rooms 120. However, it is possible to use a one-to—many
`
`correspondence relation between the air ventilating devices 150 and the bed rooms 120. That is,
`
`one air ventilating device 150 communicates with a plurality of bed rooms 120. The air
`
`ventilating device 150 may be provided with a plurality of air outlets, and each air outlet
`
`corresponds to a bed room 120. Alternatively, the air ventilating device 150 may be provided
`
`with only one air outlet, and the one air outlet communicates with the plurality of bed rooms
`
`120 through a Y—shaped three—way duct.
`
`Second Embodiment
`
`Fig. 4 is a schematic view of an air conditioning system according to a second embodiment
`
`of the present invention. In the second embodiment, a dwelling house is taken as an example as
`
`in the first embodiment. A main room may be a sitting room, and a sub-room may be a bed
`
`room, a reading room or a kitchen or other room. For the sake of description, Fig. 4 shows two
`
`bed rooms. However, the number of the bed rooms is not limited. There may be one or more
`
`bed rooms.
`
`The second embodiment differs from thefirst embodiment in that the air ventilating device
`
`150 is provided with a control part 210 therein, and the sitting room 110 or thebed room 120 is
`
`provided with a remote controller 220 which is disposed at a position on the wall of the sitting
`
`room 110 or thebed room 120 reachable by a hand of a user and which communicates with the
`
`control part 210 for setting a temperature or an air flow amount. The bed room 120 is provided
`
`with a temperature sensor 230 communicating with the control part 210.
`
`Further, although the control part 210 and the remote controller 220 are shown to
`
`communicate with each other by a wireless connection, a wire connection therebetween is also
`4
`
`10
`
`15
`
`20
`
`25
`
`30
`
`35
`
`

`

`F1140396
`
`possible. Although the temperature sensor 230 and the control part 210 are shown to
`
`communicate with each other by a wireless connection, a wire connection therebetween is also
`
`possible.
`
`With the above configuration, the air flow amount from the air exiting part 160, which has
`
`been conditioned by the air conditioner 140 in the sitting room 110, can be adjusted by the
`
`remote controller 220. Specifically, for example, buttons (not shown) of the remote controller
`
`220 representing high, intermediate and low air flow amounts on can be pressed, and then the
`
`remote controller 220 transmits a signal and the control part 210 receives the signal to
`
`determine the air flow amount of the air ventilating device 150.
`
`Thus, With the above configuration, the air flow amount blowing toward the bed room 120
`
`can be easily set and the temperature in the bed room 120 can also be easily adjusted at hand.
`
`Third Embodiment
`
`Fig. 5 is a sectional View of an air conditioning system according to a third embodiment of
`
`the present invention.
`The third embodiment differs from the first embodiment in that‘an air exiting part 310 and
`
`an air ventilating device 320 are disposed at a lower portion of a side wall 340 of a bed room
`
`330.
`
`With the above configuration, the air 380 (shown by dashed line) after conditioned by the
`
`air conditioner (not shown) in a sitting room 350 is sucked by the air ventilating device 320 and
`
`then is discharged toward the bed room 330 from the air exiting part 310 disposed at the lower
`portion of the bed room 330 through a duct 360 connected with the air exiting part 310.
`
`Further, the ventilating device 320 or the air exiting part 310 may be mounted at a position
`
`10
`
`15
`
`20
`
`where a person may stand. In this way, it will be easy to mount the ventilating device 320 or the
`air exiting part 310 in the bed room 330.
`
`25
`
`Further, when the air blowing off from the air conditioner in the Sitting room 350 is heated
`
`air, since the heated air will rise up, and the heated air is blown off at the lower portion of the
`
`bed room 330, there will be a homogeneous heating effect in the whole bed room 330.
`
`Further, when the remote controller 220 is used to set a desired temperature, a signal is
`
`transmitted from the remote controller 220 to the control part 210. The temperatUre sensor 230
`
`detects the temperature in the bed room330, and then the temperature set by the remote
`
`controller 220 is compared with the temperature detected by the temperature sensor 230, if the
`
`temperature difference is large, a large amount of air is blown off; if the temperature difference
`
`is small, a less amount of air is blown off.
`
`Therefore, with the above configuration, the air flow amount in the bed room 330 can be
`
`easily set, and the air flow amount in the bed room 330 can be easily adjusted at hand.

`
`30
`
`35
`
`

`

`FIl40396
`
`Further, the air ventilating device 320 may use a well—known fan and a motor such as a DC
`
`motor. With the DC motor, when the air amount needs to be controlled to a certain amount, a
`
`rotary speed of the DC motor can be finely adjusted.
`
`Further, the air ventilating device 320 or the air exiting part 310 may be provided with an
`
`electrostatic atomizer (not shown) so that negative ions in water can be blown toward the bed
`
`room 330 and produce a deodorizing effect.
`
`10
`
`15
`
`20
`
`25
`
`In all the above embodiments, the air conditioner may be replaced with an air ventilating
`
`device for sucking fresh outdoor air. In these cases, the concept of the present invention can
`
`also apply. That is, a main room is provided with an air ventilating apparatus communicating
`
`with the outdoor for sucking outdoor fresh air into the main room and an air ventilating device
`
`communicating with a sub—room for discharging fresh air in the main room to an air exiting part
`
`in the sub-room. As compared with a case in which each sub—room is provided with an air
`
`ventilating device communicating with the outdoor, according to the concept of the present
`
`invention, it does not need to perforate a hole in a wall of the bed room adjacent to the outdoor.
`
`Therefore, the rain or the like in the outdoor can be prevented from entering the sub—room.
`
`Further, because there is no fan motor provided at the air exiting part in the sub—room, no
`
`running noise will be generated. The user in the sub-room can have a quiet environment for rest.
`
`Of course, both an air conditioner and an air ventilating apparatus communicating with the
`
`outdoor can be provided in the main room, and the air in the main room can be transmitted to
`
`the sub—room by an air ventilating device communicating with the sub—room. In this way, both
`
`the air having been conditioned by. the air conditioner and the fresh air from the outdoor can be
`
`transmitted to the sub—room as desired by a user, and it is not necessary to provide an air
`
`ventilating device in the sub—room.
`
`As mentioned above, a sitting room is just an example of a main room. It is possible that a
`
`machine room (a room where machinery equipments are installed) or a bed room serves as a
`
`main room according to actual environment in use. If a main room is a machine room, all the
`other rooms of the dweller can have a low noise. On the other hand, considering that a room
`
`where a dweller is often present needs to be air-conditioned much, a bed room can also be used
`
`30
`
`as a main room.
`
`Although several exemplary embodiments have been shown and described, it would be
`
`appreciated by those skilled in the art that various changes or modifications may be made in
`
`these embodiments without departing from the principles and spirit of the disclosure, the scope
`
`35
`
`of which is defined in the claims and their equivalents.
`
`
