Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to increase the indoor office space, reduce the building floor height, and significantly reduce the air conditioning machine room, and at the same time reduce the heat generated in the indoor perimeter zone and interior zone during cooling and heating operations The present invention relates to an air conditioner for buildings, which is characterized by being able to easily and economically handle loads and effectively condition indoor air.

Conventionally, the central system and the individual unit system are widely known as air conditioning systems for general buildings. However, with the central system, it is usually necessary to install a relatively long duct from the air-conditioning machine room installed in one part of the building to the air-conditioned room, which requires a large amount of transport power and requires a large amount of transport power. heat loss is large. In addition, in a unit system in which small air conditioners such as fan coil units are installed in a distributed manner, there is a perimeter zone, which is the part of the wall that is close to the glass windows and external walls that form the boundary between the outdoors and the indoors, and an interior zone, which is the part that is far from the wall. Due to the difference in heat load characteristics between Mixed losses occur.
Another method is to install a small air conditioner on the waist wall of the outer wall and blow air directly. Although this method is economical, it cannot adequately deal with the difference in heat load characteristics between the perimeter zone and the interior zone when the depth of the room is large, and in addition, the airflow does not reach the depths of the room. The disadvantage is that it cannot be expected to reach a sufficient level, and the indoor thermal environment is unfavorable.

The applicant of the present invention has previously improved the shortcomings of these known air conditioning systems, and has aimed to reduce costs by simplifying the system while maintaining a good indoor environment, and has also improved the transport power. In order to save energy, the window load is handled by airflow along the indoor window surface, and return air and outside air are cooled by air conditioners installed in the ceiling near the window.
We announced an "air conditioning system that utilizes the space above the window," which was configured to heat the air and then return it to the room.
No. 208060).

However, this "air conditioner" eliminates the drawback that the air conditioner, which consists of a fan coil unit or heat pump unit, is all housed in the space under the ceiling, so the space under the ceiling needs to be raised, resulting in a higher floor height. I couldn't do it.

Therefore, the present invention makes it possible to reduce the required floor height as much as possible by arranging the indoor unit part and the outdoor unit part of the air conditioner, one in the ceiling and the other in the curtain wall. This is what I did. More specifically, the present invention provides for integrally installing an outdoor unit section of an air conditioner and an indoor air distribution device section for window load treatment within a curtain wall, and also installing an indoor unit section of the air conditioner. An air conditioner that is integrally installed in a transverse space so as to be connected to a ceiling ventilation panel to form the indoor ceiling surface, and thus has the function of cooling, heating, and ventilation as a whole, and at the same time has the function of blocking heat from outside air. The purpose is to provide the following.

A specific example will be described below.

In Figure 1, CL is the ceiling surface, FL is the floor surface,
An indoor office space 10 is located between CL and FL. The space 10 is isolated from the outside by a curtain wall 12. The curtain wall 12 is
a window portion 18 made of glass 14 and brand 16;
The waist wall portion 20 below the window portion 18 and the window portion 18
and a window upper wall portion 22 located above the window.

A blower 24 is housed in the waist wall 20, and ventilation openings 26 and 28 are provided in the lower part of the waist wall 20 on the indoor side and on the window side, respectively. It forms an air circulation device section, which functions as a blower unit.

A ventilation passage 3 is provided between the window 18 and the blind 16 and the glass 14, which are each attached by a known method.
0 is formed, and the waist wall portion 20 is connected to the ventilation path 30.
The ventilation openings 28 are in communication with each other.

On the other hand, the window upper wall portion 22 is preferably divided into two upper and lower chambers by an inclined partition plate 32. A compressor 36 is housed in the lower chamber 34, and the chamber 34
4 has a ventilation opening 37 leading from the ventilation path 30.
is provided. Furthermore, this lower chamber 34 has an opening 40 leading to a ceiling air duct 38 provided in the ceiling of the indoor office space 10. On the other hand, in the upper chamber 42, a blower 44 and a heat exchange coil 46 of the outdoor unit are arranged. In addition, an outside air intake opening 48 and an exhaust opening 50 are provided in the lower part of the blower 44 and the upper part of the heat exchange coil 46 in the upper chamber 42, respectively, at locations facing the outdoors.
This upper chamber 42 functions as an outdoor unit.

As shown in FIG. 3, a part of the partition plate 32 that divides the window upper wall 22 into an upper chamber 42 and a lower chamber 34 (the left end in the figure) is cut out, and the upper and lower chambers 42 are connected to each other through the partition plate 32. , 34 are formed to communicate with each other. Further, another part of the partition plate 32 (the right end in the figure) is cut out so that part of the outside air taken in from the outside air intake opening 48 can directly flow into the opening 40. An inflow hole 54 is formed as shown in FIG.

A transverse space 56 is provided between the ceiling air duct 38 and the opening 40 of the lower chamber 34. this space 5
A blower 58 and a heat exchange coil 60 for the indoor unit are housed in the indoor unit 6.

This transverse space 56 is open at the left and right ends in the figure, and most of the airflow from the lower chamber 34 deflected by the partition plate 32 is sent to the indoor space 10 via the ceiling air duct 38 after being subjected to temperature and humidity processing. It functions as an indoor unit. This ceiling air duct 38
and the transverse space 56 near the window constitute a ceiling ventilation panel.

It will be understood that in the present invention, if the outer and inner wall surfaces of the blower unit 20 and the window upper wall 22 are made of a heat insulating material, the cooling/heating/ventilation function can be increased.

When the device of the present invention is used as a cooling device, a switch (not shown) for operating the upper chamber or outdoor unit 42 and the transverse space or indoor unit 56 is operated to turn on the heat exchange coil 46 in the outdoor unit 42. The compressor 36 is controlled so that the condenser and heat exchange coil 60 in the indoor unit 56 function as an evaporator. When the blowers 24, 44, and 58 are driven, air in the indoor space 10 is sucked in through the ventilation opening 26 of the blower unit 20 as indicated by an arrow 62. Indoor air sucked into the ventilation unit 20 enters the ventilation path 30 of the window portion 18 from the ventilation opening 28 above it as shown by the arrow 64, and as a result of processing the window surface load in the ventilation path 30, the temperature rises. The air enters the lower chamber 34 of the window upper wall 22 through the ventilation opening 37 as shown by the arrow 66. Lower chamber 34
Most of the high-temperature air that entered the room rises as shown by arrow 68 (FIG. 3), contacts the partition plate 32, and is guided into the indoor unit 56 as shown by arrow 70 as indoor circulating air. be done. Indoor unit 5
The air that has become high temperature inside 6 undergoes heat exchange to become low temperature, and is sent to the ceiling ventilation duct 38 as shown by arrow 72. After that, it is guided to the back of the room through the duct 38, and then is sent as shown by arrow 74. It is then returned to the room through an opening such as a slit. In this way, cooling of the indoor space 10 is achieved.

Indoor air contaminated with cigarette smoke etc. is stored in the lower chamber 3.
4, a part of it flows into the upper chamber 42 through the communication hole 52 as shown by arrow 76, and is discharged outside from the exhaust opening 50 as shown by arrow 78 (FIG. 3). On the other hand, fresh outside air is introduced into the outdoor unit 42 from the outside air intake 48 as indicated by arrow 80.
Most of the fresh air is directed upward as shown by the arrow 82 by the partition plate 32 and returned to the outside air through the heat exchange coil 46 as heat radiation air, but a portion of the fresh outside air is exchanged with the exhaust air from the room. The inflow hole 54 can be opened as shown by the arrow 84 without being interfered with by the partition plate 32.
The water is replenished into the indoor unit 56 via. In this way, ventilation of the room is achieved at the same time.

On the other hand, when the device of the present invention is used as a heating device, the heat exchange coil 46 of the outdoor unit 42 is adjusted so as to function as an evaporator, and the heat exchange coil 60 of the indoor unit 56 is adjusted so as to function as a condenser. As a result, heating of the room and ventilation of the room air can be achieved at the same time through air circulation similar to the case described above. Of course, in this case, most of the outside air 82 taken in from the outside air intake opening 48 acts as heat-absorbing air.

In this way, the present invention forms the outdoor unit and the indoor unit separately, places only the indoor unit in the ceiling, places the outdoor unit in the upper wall of the window, and places the indoor air distribution device part in the lower part of the window surface. It was placed inside the waist wall. This releases (suctions) the inside of the outdoor unit.
The hot air can be circulated, and the air blown out from the indoor air circulation system, that is, the blower unit, rises along the window surface and is sucked into the upper wall of the window, whereupon most of it is returned to the indoor unit as circulating air. A portion is discharged outdoors through the outdoor unit. Further, circulating air and some fresh outside air flow into the indoor unit to cool (heat) the air, and these two units constitute a heat pump. Furthermore, the outer inner wall surfaces of the window upper wall portion and waist wall portion and the window surface have a heat insulating function. Therefore, the present invention can achieve air conditioning, heating, and ventilation functions in an energy-saving manner, and can improve the efficiency of construction work by producing and installing an air conditioner integrally with a curtain wall or ceiling panel. In this way, the present invention solves the problem of the reduction of indoor office space due to the floor-mounted unit type air conditioner installed near the exterior wall occupying the wall, and the problem of increased floor height due to the ceiling-mounted unit type air conditioner occupying the inside of the ceiling. For example, the air for window load treatment shown in Japanese Patent Publication No. 58-10653 is sucked into the ceiling through an opening provided in the ceiling close to the top of the window, causing high temperatures in the ceiling duct in the summer. This is a solution that all at once solves the problem of negative thermal effects on the room caused by low-temperature flow in winter.
