Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an air cooling system for office buildings that can cope with the increase in air conditioning load associated with office buildings becoming more OA and intelligent.

[Conventional technology]

With office automation (OA) attracting attention these days, there is an increasing demand for intelligent buildings and their parts that can accommodate office automation. OA equipment itself becomes a heat source, so
When OA equipment is centrally located, it becomes necessary to install additional air conditioning equipment to cope with the increased air conditioning load.

Normally, when blowing air from one air conditioner to several rooms, if the load fluctuations in each room do not change at the same ratio,
This will cause deviations in temperature and humidity in each room. For example, if each room has a different orientation, large deviations in room temperature will occur due to the influence of solar radiation. Zoning is performed to eliminate such deviations, and one form of zoning is adopted in office buildings, where each direction is divided into a pen meter zone (outer area) and an interior zone (inside). Conventionally, in this type of system, the increase in air conditioning load has been handled by using a variable air volume device for interior air conditioning.

[Problem that the invention attempts to solve]

However, when dealing with variable air volume devices for interior air conditioning as described above, there is a problem that the number of variable air volume devices increases when considering booth partitions and support for small-lot tenants, and it is not possible to provide sufficient support due to the initial cost. be. Also, actually
The increased air conditioning load due to the centralized installation of OA equipment requires the installation of additional air conditioning equipment and the necessary wiring and piping, resulting in large-scale remodeling work. Therefore, future
Dealing with the increase in air conditioning load due to the addition of OA equipment has become a major design point.

The present invention is based on the above consideration, and
The object of the present invention is to provide an air cooling system for an office building that can easily and inexpensively accommodate an increase in air conditioning capacity.

[Means for solving problems]

Therefore, the office building air cooling system of this invention is
A slit is installed in the outside wall to introduce outside air, and a chamber and an air-cooling heat pump unit are installed in the ceiling. Outside air is brought in through the slit, and the chamber reduces the wind speed to prevent rainwater from entering, and air is blown into the room for air conditioning. It is characterized by having been configured.

[Effect]

In the air cooling system for office buildings of this invention, outside air is introduced from the chamber in the ceiling to the air-cooled heat pump unit through slits in the exterior wall, so the chamber can reduce the wind speed and prevent rainwater from entering, thereby reducing the air conditioning load. It becomes easier to deal with. Furthermore, by providing the chamber, the duct can be smoothly connected between the slit and the air-cooled heat pump unit.

〔Example〕

Examples will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view of the building showing one embodiment of the air cooling system for an office building according to the present invention, and FIG. 2 is a front view of FIG. 1. In the figure, 1 is a slit, 2,
3 and 6 are outer walls, 4 and 5 are glass windows, 7 is a chamber, 8 is an air-cooled heat pump unit, 9 and 10 are air outlets, and 11 is a ceiling.

In Figure 1, one floor of the office is covered with, for example, an aluminum curtain wall (anodized).
and glass windows 4, 5 made of, for example, heat-reflecting glass.
In the air cooling system for an office building according to the present invention, slits 1 for air supply and exhaust are provided in the outer wall 3 located above the office ceiling. Then, outside air is introduced from here, passed through the chamber 7, and sent to the ceiling-concealed air-cooled heat pump unit 8, and the air cooled here is blown into the office from the air outlets 9 and 10, thereby supplying air to the perimeter zone. air conditioning.

By doing this, it is possible to smoothly accommodate future increases in air conditioning load and air conditioning of small rooms due to the addition of air-cooled heat pump units in the ceiling or the addition of air outlets in the ceiling. The chamber 7 reduces the wind speed of the outside air introduced through the slit 1 of the outer wall 3 and prevents rainwater from entering.
This makes the duct connection between the

The second figure shows the front view of the office shown in Figure 1.
It is a diagram. Assuming that four slits 1 are provided in one span as in the example shown in Figure 2, two of these sections will initially be used for air conditioning, and the remaining two sections will be used for expansion to improve air conditioning in the future. Increased load and small room air conditioning can be handled smoothly.

Note that the present invention can be modified in various ways and is not limited to the above embodiments.

[Effect of idea]

As is clear from the above description, according to the present invention, since the air-cooled heat pump unit is of the ceiling concealed type, it is possible to easily cope with increased loads not only in the perimeter zone but also in the interior zone.
Additionally, if it becomes necessary to handle increased air conditioning loads in the future, it is only necessary to install additional air-cooled heat pump units individually, so the interior air conditioning ducts are not affected and the capacity of the air conditioner can be reduced. Therefore, tenant construction becomes easy and the initial cost of the air conditioner can be reduced. Furthermore, since perimeter air conditioning costs can be calculated for each tenant, air conditioning can be handled smoothly during overtime.
