It is a schematic diagram which shows the flow of the warm air at the time of heating in the same embodiment. It is a schematic diagram which shows the flow of the cool air at the time of air_conditioning | cooling in the same embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic diagram of a heating / cooling system 1 (air conditioner) showing an embodiment of the present invention. The heating / cooling system 1 of the present embodiment is used for heating / cooling a room A and a bathroom B on the first floor of a two-story house.

  The heating / cooling system 1 includes an outdoor unit 2, an indoor unit 3, an outlet 4 for the bathroom B, an outlet 5 for the living room A, and a remote controller (not shown). These are well known.

  The indoor unit 3 is disposed on the back side of the ceiling 20 of the hallway C between the living room A and the bathroom B. The indoor unit 3 is connected to the outdoor unit 2 by a refrigerant pipe 6. The indoor unit 3 may be arranged on the ceiling or storage space of a room near the living room A.

  The remote controller is used for the user to control the operation of the indoor unit 3. Specifically, it is possible to change the blowing direction of warm air and cold air, adjust the temperature, and the like by operating the remote controller.

  The bathroom outlet 4 is used to blow hot air or cold air into the bathroom B. The outlet 4 is provided in the upper part of the wall surface of the bathroom B, and is connected to the indoor unit 3 through the duct 7.

  The air outlet 5 for the living room A is used for blowing hot air or cold air into the living room A. There are a plurality of outlets 5, and each outlet 5 is connected to the indoor unit 3 via a duct 8 disposed on the back side of the ceiling 10. Note that the duct 8 may be connected to each outlet 5 and the indoor unit 3, or may be connected to each outlet 5 by branching one end of one duct.

  The plurality of outlets 5 are provided in a distributed manner on the ceiling 10 of the living room A. The number of outlets 5 is set according to the floor area of the room A. The position of the outlet 5 is preferably set so that warm air and cold air do not hit the furniture and the human body. In the present embodiment, as shown in FIG. 2, the outlet 5 is set at the diagonal position of the ceiling 10. A plurality of outlets may be provided in a distributed manner at a position close to the ceiling 10, for example, above the wall surface 11 of the living room A. Further, the number of outlets may be one.

  Next, a heating method and a cooling method of the living room A by the heating / cooling system 1 of the present embodiment will be described.

(heating)
As shown in FIG. 2, the heating / cooling system 1 blows warm air Wa from the outlet 5 into the room A. Specifically, the hot air Wa is blown out to reach the floor 12. Thereby, the warm air Wa strikes the floor 12 and diffuses horizontally, and the entire floor 12 is warmed.

(Air conditioning)
As shown in FIG. 3, the heating / cooling system 1 blows out the cold air Wb from the outlet 5 into the room A. Specifically, the cold air Wb is blown out so as to flow along the ceiling 10. As a result, the cold air Wb diffuses horizontally in the vicinity of the ceiling 10 and then falls naturally, and the entire room A is cooled.

  Thus, in the heating / cooling system of the present embodiment, the outlet 5 is provided in the ceiling 10 of the living room A or in the vicinity thereof so that the hot air can be blown out so as to reach the floor 12 during heating. Therefore, the entire floor 12 can be heated without using expensive members as in the floor heating system. In addition, it is possible to perform cooling that cannot be realized by the floor heating system. Therefore, the heating / cooling system 1 of this Embodiment can implement | achieve favorable comfort at the time of heating / cooling, suppressing construction cost. Further, during cooling, the entire interior of the room A is cooled by allowing the cold air Wb to flow out so as to flow along the ceiling 10, so that the cooling efficiency in the room A can be increased.

In addition, it is preferable to set the wind speed of the warm air Wa larger than the wind speed of the cool air Wb. For example, assuming that the standard floor area is 22.6 m ² (equivalent to 14 tatami mats) and the ceiling height is 2.5 m, the temperature of the warm air is 3 m / s to transmit heat to the floor 12 during heating. As mentioned above, Preferably, it sets to around 4 m / s and sets the wind speed of cold wind to 2 m / s or less.

  As shown in FIG. 1, the warm air Wa blown into the room A flows into the hallway C through an undercut (not shown) of the door of the room A. The indoor unit 3 sucks the warm air Wa flowing in the hallway C and blows it out into the living room A again. Although not shown, the same applies to the case of the cold air Wb.

  Thus, the warm air Wa (cold air Wb) used for heating / cooling the living room A circulates in the order of the living room A → the corridor C → the back of the ceiling 20 of the corridor C → the back of the ceiling 10 of the living room A. Therefore, it is possible to simultaneously heat and cool a place (corridor C) that is not a living room. Therefore, the heating / cooling system 1 of this Embodiment can implement | achieve higher comfort.

  Further, by sucking the warm air Wa (cold air Wb) from the corridor C, there is no shortcut with the warm air Wa (cold air Wb) blown into the room A. Therefore, heating / cooling can be performed efficiently and energy saving can be improved. Further, since the temperature in the living room A is not uneven, higher comfort can be realized.

  In addition, when the bathroom B is heated and cooled as shown in FIG. 1, the warm air Wa (cold air Wb) is blown out into the bathroom B from the outlet 4 for the bathroom B. The hot air Wa (cold air Wb) blown into the bathroom B flows into the corridor C through the undercut (not shown) of the door of the bathroom B, and the indoor unit 3 sucks the hot air Wa (cold air Wb). Blow out again into bathroom B.

  In this way, the warm air Wa and the cool air Wb used for heating and cooling the bathroom B circulate in the order from the bathroom B → the corridor C → the back side of the ceiling 20 of the corridor C. Therefore, also in this case, it is possible to simultaneously heat and cool a place (corridor C) that is not bathroom B. Therefore, the heating / cooling system 1 of this Embodiment can implement | achieve higher comfort.

  Moreover, in the heating / cooling system 1 of this Embodiment, since the user can change the blowing direction of the warm air Wa or the cold air Wb by operating the remote controller, the warm air Wa or the cool air Wb is blown according to the user's preference. The direction can be adjusted, and higher comfort can be realized.

  As mentioned above, although embodiment concerning this invention was illustrated, this embodiment does not limit the content of this invention. Various modifications can be made without departing from the scope of the claims of the present invention.

  For example, in the heating / cooling system 1 according to the present embodiment, the present invention is applied to a room on the first floor. Even in that case, an effect similar to the effect described in the present embodiment can be obtained.

  As described above, the heating / cooling system of the present invention can achieve good comfort during heating / cooling while suppressing the construction cost. Therefore, the heating / cooling system of the present invention can be fully utilized in the technical field of heating / cooling systems.
