[0007]

[Function] The airframe 1 is installed at a predetermined location in the room, and the return air or the outside air through the duct passes through the suction port 2 and the suction side passage A
In driving the fan motor 4 in such a state that flows into the inside, the air flows into the outlet side passage B, and at the same time, the heat exchange coil 3 exchanges cold and warm heat to an appropriate temperature, and the cold and warm air is blown into the upper part of the body 1. It is fed into each room through the duct from the air outlet 6 which can be opened. Simultaneously with the above, by operating the dampers c to f of the outdoor air processing side unit, a part of the heat amount of the return air from the room is effectively used by the action of the total heat exchanger 12 without discarding the entire amount of the return air from the room. It can be done. That is, when the indoor air processing unit is driven, the return air from the room is opened by opening c and f and opening d.
After passing through, the air is sent to the indoor air processing unit together with the fresh outside air, and the air is sent from the air outlet 6 into each room. Also c and f
And all the polluted air that is returned to the air by the open circuit of d is released to the outdoors, but during that time, the air that also serves as the outside air passes through the total heat exchanger 12 and is released, so that the amount of heat in the air is entirely reduced. Heat recovery is performed in the heat exchanger 12. Further, at the same time as the above-mentioned operation, it is possible to directly send the return air that is reduced by opening and closing the bypass dampers e and f to the indoor air processing unit. It is possible to request air conditioner management that can respond to multiple purposes.

According to the second aspect of the present invention, the wind direction switching dampers a and b provided at the upper and lower positions in the front air passage of the heat exchange coil 3 are opened and closed, that is, at the upper portion. By opening the damper a and closing the lower damper b, only cold air is discharged from the upper outlet 6a, and conversely to the above, by closing the upper damper a and opening the lower damper b, only warm air is discharged. It is possible to easily obtain optimum head cold and foot heat effects as an indoor environment, such as being able to blow out from the lower outlet 6b, and by opening and closing the upper and lower dampers a and b at the same time. Therefore, the optimum temperature distribution can be easily obtained.

Each fan blower opening is provided in the outlet side passage B on the adjacent side. Although the description of the structure of the fan motor 4 is omitted, the fan motor 4 has a built-in electric motor integrally with the conventional blower, and is extremely miniaturized. In the blow-out side passage B, a heat exchange coil 3 having a thin vertical shape or an appropriate shape is obliquely arranged in a horizontal slanting manner in the center of the inside so that the width of the blower passage is vertically shortened to have a short width. The heat exchange coil 3 is a cold / hot water coil for cold water and hot water, and the heat exchange for both cold / heat switching can be arbitrarily changed by operating the valve 14. Reference numeral 15 in the figure denotes a drain pan and a humidifier 16.

The detailed description of the operation of these operations is as described in the section of the operation. Further, the dampers a and b are short-circuited with the damper motor 17 so that the damper motor 17 can be alternately opened and closed and opened and closed at the same time. It is going to send the cold and warm air of the above into the room from the arbitrary upper and lower outlets 6. Further, according to the present invention, the upper and lower wind direction switching dampers a and b are connected to a temperature sensor or the like which is installed in advance inside the room to automatically open and close the chamber. Not only is it possible to send the specified warm and cool air up and down in any direction in the room, but it is also possible to incorporate a mechanism such as a computer to adjust the water flow to the coil, control opening and closing, and change the hot and cold passages. Needless to say, it can be used more reliably and conveniently by automatically managing the operation.

As described above, according to the present invention, the inside of the machine body is divided by the partition plate into both the blowing passages of the suction side passage A and the blowing side passage B, and several fan motors are provided in the suction side passage A. Are arranged in series in the vertical axis direction, and a vertical total heat exchanger is air-treated adjacent to an indoor air treatment unit in which a heat exchange coil is obliquely arranged in the outlet side passage B with respect to the horizontal direction. It is possible to reduce the installation area drastically by forming an air conditioner with an extremely thin overall structure because it is integrally configured with an outside air treatment type that can be installed in the side air passage. It has a remarkable effect. Particularly, in the present invention, since the heat exchange coils are obliquely arranged as described above, not only the thin formation but also the airflow discharged in the direction of rotation of the blower flows very smoothly due to the oblique formation. Since the air is in contact with the entire surface, it is extremely good in terms of thermal efficiency, and it is possible to effectively use the amount of heat that was conventionally discarded by installing a total heat exchanger. Let's say so.

Further, according to the second aspect of the present invention, since the wind direction switching dampers a and b are provided at the upper and lower portions of the outlet passage B respectively, the vertical switching adjustment operation of the dampers is performed. Cooling and warming air can be easily supplied in accordance with various indoor conditions, and an optimal effective temperature distribution for the indoor environment as, for example, head cold foot heat can be easily obtained.

Further, by integrally connecting the upper and lower muffling chambers to the blowout side passage B as in claim 3, there is an effect that a very quiet air conditioning expansion can be obtained at the same time.
