BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor air conditioning system, and more particularly to an air conditioning system capable of effectively performing cooling and heating air conditioning of the entire room by effectively utilizing a ceiling portion.

[0002]

2. Description of the Related Art As a conventional indoor air conditioning system of this type, a fan coil air conditioning system shown in FIG. 3 and a duct air conditioning system shown in FIG. 4 have been generally implemented.
That is, the fan coil air conditioner system shown in FIG. 3 is a system in which the air conditioner indoor unit 1 is installed on the floor 3 of the room 2 and cold and warm air is blown from the air conditioner indoor unit 1 into the room 2. The duct air-conditioning system shown in FIG. 4 is a system in which the duct 4 is passed through the attic space, and cool and warm air is blown downward from the duct 4 toward the interior of the room 2.

[0003]

However, in both the fan coil air conditioner system and the duct air conditioner system described above, the cooling radiant heat 5 from the ceiling surface cannot be cut as shown in FIGS. There was a problem of poor sex. Further, in both of the above methods, since the ceiling is high with a slope, warm air during heating stays in the ceiling portion, resulting in poor heating efficiency and energy saving. Further, since the air conditioner indoor unit 1 and the air outlet of the duct 4 are partial, it is difficult to make the room temperature of the entire room 2 uniform.

The air-conditioning system according to the present invention is a technique developed in view of the above-mentioned conventional problems, and in particular, by forming a double structure on the sloping ceiling surface, the intermediate layer serves as a planar duct to cool and warm air. It is intended to provide an air-conditioning system capable of passing cooling / heating air evenly throughout the room below to perform comfortable cooling / heating and to significantly enhance cooling / heating efficiency.

[0005]

The air-conditioning system according to the present invention is a technique that has fundamentally improved the above-mentioned conventional problems, and its gist is an air-conditioning system for heating and cooling the attic and the sloping ceiling space. A second duct is provided at a predetermined interval in the slope ceiling to form a double structure, thereby forming a planar duct in the ceiling by the slope ceiling and the second slope, and The air conditioning system is characterized in that the air outlets of the planar ducts are widened in the lower part of both sides of the room.

[0006]

As described above, the air conditioning system according to the present invention has the double structure in which the second sloped ceiling is provided at a predetermined interval in the sloped ceiling so as to have a double structure. It is possible to configure a planar duct that allows cold and warm air to pass therethrough. Therefore, the air outlets of the planar ducts formed between the sloped ceiling surface and the second sloped ceiling can inevitably be provided widely in both lower parts on both sides of the room. The cold and warm air from the heat exchange air can be brought under the ridge with a ceiling ceiling and run over the entire length of the ridge, and can be connected to the above-mentioned planar duct.

[0007] In addition, during cooling, the radiant heat is cut by cooling with cold air, and the radiant cooling and the convection cooling can be performed by blowing out cool air from the planar duct, thereby improving the sensible feeling. . Also, during heating,
By blowing warm air widely downward from the lower parts on both sides of the room, it is possible to achieve energy-saving heating with a coil together with radiant heating on the ceiling surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The air conditioning system according to the present invention will be described with reference to the drawings. FIG. 1 is a simplified cross-sectional explanatory view showing the essential parts of the configuration of the air conditioning system of the present invention, and FIG. 2 is a simplified external view of the essential parts of FIG. . In FIG. 1 and FIG. 2, reference numeral 11 denotes a sloped ceiling surface, and a second sloped ceiling 12 is provided inside the sloped ceiling surface 11 at a predetermined parallel interval, whereby the ceiling portion is provided. Has a double structure.

The sloped ceiling surface 11 and the second sloped ceiling 12 form a wide sheet-like duct 13 in the ceiling portion, and the outlets 14 of the sheet-like duct 13 are widened to the lower portions on both sides of the room 15. It is provided and configured. Reference numeral 16 in the drawing denotes an air conditioner outdoor unit, an air conditioner such as a boiler, and the like.
The heat exchanger 17 connected to is arranged in the planar duct 13. Reference numeral 18 is an example in which a blower fan is installed in the planar duct 13. Further, it is a method in which a heat exchanger is placed on the outdoor unit side and the air conditioner side, and air is blown to the planar duct 13 by a duct.

In the air conditioning system according to the present invention, as described above, the ceiling portion has a double structure and the planar duct 13 is provided, and the air outlets 14 of the planar duct 13 are widely provided in the lower portions on both sides of the room 15. Therefore, these wide outlets 14
The cooler and warmer air can be blown out broadly downward on both sides of the room 15, whereby convection is generated in the entire room 15 and mild and efficient cooling and heating can be performed.
When cooling in the summer, since the ceiling surface is cooled by the cool air passing through the planar duct 13, it is possible to cut radiant heat.

Further, by blowing out cool air from the air outlet 14 of the planar duct 13 to the lower sides of the room 15, both radiation cooling and convection cooling can be performed, and the sensation can be improved. At the time of heating in winter, by blowing warm air to the lower sides of the room 15, it is possible to effectively perform mild and energy-saving indoor heating together with radiant heating of the ceiling surface.

Since the air-conditioning system of the present invention has the above-mentioned structure, it enables high-temperature cooling and low-temperature heating to the extent that the condensation problem of the planar duct 13 can be prevented. It can be configured by using a wood-based material or a material such as gypsum board, which can reduce the equipment cost. Also, it is possible to attach a cloth to the ceiling surface.

[0013]

Since the air conditioning system according to the present invention has the above-mentioned structure and operation, it is possible to widely blow the cool and warm air downward from both sides of the room through the planar duct, thereby causing convection to the entire room. It is possible to generate and mix cold and warm air in the room well to provide mild cold and warm air. In addition, it is possible to prevent the cold and warm air from concentrating on the floor or ceiling of the room, which makes it possible to maintain a uniform temperature throughout the room and to implement efficient energy-saving cooling and heating. In addition, when cooling in the summer, cooling radiant heat from the ceiling surface can be cut off, which makes it possible to carry out cooling with an extremely high sensation. Furthermore, the air-conditioning system of the present invention can be easily constructed by using commonly used wood-based materials or gypsum board-based materials,
It has a feature that the equipment cost can be reduced.
