Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel structure building such as a mid-rise factory or school, and more particularly to a building integrated cooling and heating system in which the steel structure of the building is integrally provided with a cooling and heating function.

[0002]

2. Description of the Related Art As described in, for example, Japanese Patent Application Laid-Open No. 63-201237, in order to improve the fire resistance of a steel frame building, a steel frame structure is constructed by using steel pipe columns or steel pipe beams. A method of filling water into the hollow portion of a steel pipe column or steel pipe beam is known. When some of the columns and beams are exposed to the flame due to a fire in this building, the water temperature in the steel pipes rises, and convection occurs in the pipe line where many steel pipes are continuous. Therefore, the part that received the heat of the flame will be cooled by the water in the pipeline,
It is possible to effectively prevent the structure from being locally overheated. In this structure, when the water in the locally heated steel pipe evaporates, its vapor pressure is appropriately released, and
It is also known to add a mechanism for filling the shortage of water from the tank into the pipeline to enhance the water-cooled fireproof function.

[0003]

The water-cooled steel pipe structure described above can greatly enhance the fire resistance of a steel structure building. However, in order to implement this water-cooled refractory structure, there is a problem that the construction cost is considerably increased as compared with a general steel structure building. In order to manufacture a pipeline system that does not leak water by connecting steel pipe columns or steel pipe beams to each other, it requires a large amount of construction cost and a long construction period. In addition, a water tank mechanism for constantly filling water in the pipeline and a safety valve mechanism for appropriately releasing the steam generated in the pipeline are added to detect water leakage in the pipeline promptly. A maintenance and inspection system is also required.

[0004] In this way, while the equipment investment greatly increases, the equipment functions effectively in an abnormal situation such as a fire. Therefore, even if the effect of improving the fire resistance is known, it is the fact that this type of water-cooled fire resistant structure is not widely used in consideration of the cost.

An object of the present invention is to effectively utilize the water-cooled refractory structure of filling a pipe system connecting steel pipe columns and steel pipe beams of a steel structure building with water, and to provide a basic cooling and heating of the building on a regular basis. To make it useful.

[0006]

The building integrated cooling and heating system in a steel structure building according to the present invention is a steel structure building using a steel pipe column or a steel pipe beam, in which the pipelines of the steel pipe column and the steel pipe beam are communicated with each other. A pump mechanism for forming a water circuit so that water can be filled and circulated in the pipeline and pumping the water to the water circuit for circulation, and a cooling mechanism for cooling the water circulating in the water circuit. And a heating mechanism for heating the water circulating through the water circuit, which is attached to the building to allow the cooling mechanism and the heating mechanism to properly function as necessary.

[0007]

In the hot summer, for example, the cooling mechanism is operated to cool the circulating water while circulating the water by the pump mechanism to the water circuit formed by the steel tube columns and the steel tube beams which are in communication with each other. The heat from the outside to the building due to strong solar radiation and the heat generated in the factory in the building are absorbed by the water in the water circuit, and for example, the heat is transferred to the cooling mechanism installed on the roof and released to the outside. It This is the basic cooling of the building. Further, in the cold winter season, the circulating water in the water circuit is heated by the heating mechanism to heat the steel pipe columns and steel pipe beams from the inside, thereby providing basic heating of the building. Furthermore, since the water circuit is always filled with water, it naturally functions effectively as the above-mentioned water-cooled fireproof structure, and effectively protects the structure of the building when a fire occurs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a schematic structure of a building integrated cooling and heating system according to an embodiment of the present invention. In a steel structure building using steel pipe columns and steel pipe beams, steel pipe columns 1 and steel pipe beams 2
The pipes are connected to each other to form a water circuit W so that water can be filled and circulated in the pipes. As the steel pipe forming the water circuit W, not only a round steel pipe but also a square steel pipe such as a box type may be used. The steel pipe column 1 and the steel pipe beam 2 are connected so as to prevent water leakage. Not all columns and beams of the building are necessarily components of the water circuit W.

The building of the embodiment shown in FIG. 1 is a four-story building. A pump 3, a heater 4 and a cooling tower 5 are arranged on the roof of the building, and these are connected to a water circuit W via valves 6a and 6b. ing. As the heater 4, a heat pump driven by midnight power is suitable.

When the valve 6a is opened and the valve 6b is closed, the discharge side of the pump 3 is connected to the lower part of the water circuit W via the pipe 7, and the upper part of the water circuit W is connected to the heater 4 via the pipe 8 The discharge side of 4 is pump 3 via valve 6a
Connected to the inhalation side of. When the pump 3 is operated, the water filled in the water circuit W circulates through the heater 4 as indicated by the arrow. In this case, the water heated by the heater 4 is circulated and supplied to the water circuit. Therefore, the steel pipe columns 1 and the steel pipe beams 2 forming the water circuit W are warmed from the inside,
This is the basic heating of the entire building.

With the valve 6a closed and the valve 6b open,
Discharge side of pump 3 → lower part of water circuit W via pipe 7 → upper pipe 9 of water circuit W to cooling tower 5 → water from the discharge side of cooling tower 5 through valve 6b to the suction side of pump 3 Flows, the water inside the water circuit W absorbs heat from inside and outside the building, and the heat is transferred to the cooling tower 5 and released to the outside.
This is the basic cooling of the entire building.

EFFECTS OF THE INVENTION The above water-cooled refractory structure of filling water into a pipeline system connecting steel pipe columns and steel pipe beams of a steel structure building requires a considerable cost. I used it to do basic heating and cooling of the building. Therefore, a large capital investment is not utilized only when an abnormal situation such as a fire occurs, but this structural system can be used daily for the basic cooling and heating of the entire building, and it exerts a great effect. This heating and cooling system can significantly reduce the load on the heating and cooling equipment for each room in the building. In particular, it is effective as a basic cooling when a large amount of heat is generated in the factory in the building. In this way, since it is an additional facility with extremely high cost performance, it is also very effective in spreading this type of water-cooled fireproof structure.
