TECHNICAL FIELD

[0001] The present application relates to the field of building, in particular to a kind of building automation ventilation regulating system. BACKGROUND

[0002] Under the background of rapid development of city, more and more cities face the problem of land resource shortage and rising land cost, which restricts the development of city industry. Therefore, high-rise composite large space factory building emerges as the times require. Unlike traditional factory building, this new type of industrial building form not only has the spatial characteristics of large space factory and high-rise building, but also has high requirements for safety and indoor ventilation. In recent years, with the development of information technology and the leap of sensor technology, intelligent ventilation optimization control has entered the public's field of vision. For high-rise composite large space factory building, indoor thermal comfort can be maximized and energy consumption can be reduced through optimization and control.

[0003] In actual engineering practice, the following problems exist:

[0004] I. The high-rise factory building in the prior art generally has a top central ventilation system. However, the top ventilation structure, such as ventilation grille and filter screen, needs to be cleaned, which is not easy to clean.

[0005] II. The factory building in the prior art has a safety protection measure of fire sprinkler, which melts when the temperature of the hot melting element rises, drives the mechanism to realize sprinkling. However, the factory space is large, and the temperature rises slowly unlike a private room. There is a situation of slow sensing feedback and delayed sprinkling.

[0006] III. The fire safety sprinkler device in the prior art, such as CN105736783A, has a hot melting function, but the fixing performance is poor and cannot provide long-term sufficient stability.

[0007] IV. In the case of similar temperature changes, the falling or breaking of parts caused by temperature changes is not expected in the fire safety sprinkler device in the prior art, such as CN105736783A and CN105498145A.

[0008] V. In the fire safety sprinkler device in the prior art, the sprinkling needs to be closed to stop water by the total valve after the danger is eliminated, and then the replacement or maintenance of the sprinkling module is completed. However, the total valve controls a large range of water use, which causes a large range of sudden water stop and causes inconvenience to production and life.

[0009] VI. The curtain wall ventilation system in the prior art cannot realize intelligentization and cannot control wind force specifically, such as cannot control wind force according to environmental changes and fire changes. SUMMARY

[0010] In order to overcome the above problems, the present application proposes a solution to simultaneously solve the above problems.

[0013] The support column is provided with the main beam, the main beam is connected with the lower cross beam and the upper cross beam, and the upper cross beam and the lower cross beam are arranged in parallel; the upper cross beam is provided with the cold air pipeline, and the cold air in the cold air pipeline is delivered to the factory building through the upper cross beam; the lower cross beam is provided with the valve, and the lower cross beam comprises an upper wall and a lower wall.

[0014] The valve is provided with a water inlet connector, an upper water outlet connector and a lower water outlet connector. The driving member is arranged above the upper wall and connected with a driving shaft below the driving member. The driving shaft extends into the lower cross beam through the upper wall. The valve plug is connected with the driving shaft at the lower end of the driving shaft. The valve body is arranged in the lower cross beam. The driving member can drive the valve plug to rotate through the driving shaft. The valve plug is provided with a water inlet hole, a middle cavity, an upper water outlet hole, a lower water outlet hole and a channel. The valve body is provided with an inlet, an upper outlet, a lower outlet and a vertical hole. The lower water outlet hole is embedded with the blocking component. The lower water outlet hole is provided with the channel below. The channel is provided with a hot melt element. The hot melt element comprises an upper hot melt part and a lower hot melt part. The hot melt element supports the blocking component. The valve body is provided with a vertical hole below. The vertical hole is in communication with an opening arranged on the lower wall.

[0015] In the upper water passing state, the valve plug is rotated to make the water pass through the water inlet connector, the inlet, the water inlet hole, the middle cavity, the upper water outlet hole, the upper outlet and the upper water outlet connector in sequence. In the standby state, the valve plug is rotated to make the lower water outlet hole align with the lower outlet. The channel covers the vertical hole. The lower surface area of the lower hot melt part is greater than the sectional area of the vertical hole. The area of the opening is greater than the sectional area of the vertical hole.

[0016] Preferably, the water inlet hole extends along the circumference of the valve plug.

[0017] Preferably, the lower cross beam is provided with a pipeline support.

[0020] Preferably, in the standby state, the upper water outlet hole is not aligned with the upper outlet.

[0024] Preferably, the lower water outlet connector is connected with a lower pipeline. A shower head is arranged below the lower pipeline and extends through the lower wall.

[0025] The present application has the following advantages:

[0026] I. The first point raised in the background art is to set the cross beam in the building as an upper cross beam and a lower cross beam, both of which are hollow and arranged in parallel. The upper cross beam is provided with a refrigeration and ventilation path, and the lower cross beam is provided with a water supply path. The ventilation module in the upper cross beam blows air downward, which can be blocked by the lower cross beam, thereby preventing the cold air from blowing directly downward. The upward spraying module can clean the grille and filter screen of the ventilation module, and the downward spraying module can play the role of fire sprinkler.

[0027] II. The second point raised in the background art is that the water outlet pipe in the lower cross beam is provided with two upper and lower water outlet pipes. The upper water outlet pipe is connected to the upward spray head, and the lower water outlet pipe is connected to the downward spray head. The valve controls the flow switching or closing of the two water outlet pipes. When the danger in the factory building is small and the temperature does not rise rapidly, the valve can be manually or automatically operated to connect the upper water outlet pipe for spraying. When the danger in the factory building is large and the staff has no time or need to operate the valve, the valve melts after the temperature in the factory building rises rapidly, causing the lower water outlet pipe to be connected for automatic spraying, thereby achieving both manual and automatic spraying.

[0028] Or in the case of hot melt element melting, if the fire cannot be effectively controlled, the targeted spray water control system needs to be started. The indoor fire environment distribution is obtained by using air temperature monitoring elements combined with indoor wind speed and direction monitoring elements, and the fire development condition is predicted by CFD simulation. Based on the fire in different areas of the room, the water flow of the dot matrix distributed automatic spray head is controlled. The key areas of the fire point and the super high temperature area are sprayed in excess, the key areas of the fire development direction are sprayed, and the preventive spraying of the downwind high-risk area is carried out.

[0029] III. The third point raised in the background art is that the hot melt element is fixed below the valve plug and is provided with an upper part and a lower part. The size of the lower part is larger than the size of the hot air through hole in the valve body, so that it will not fall off and is easy to support. The hot melt element is supported by the blocking part above, thereby providing better stability. The opening area of the lower wall of the lower cross beam is larger than the area of the hot air through hole in the valve body, so that the hot air can be more fully contacted.

[0030] IV. The fourth point raised in the background art is that an opening is provided on the lower wall of the lower cross beam, and a blocking part is provided in the opening. The blocking part is mesh-shaped, so that the hot melt element can fall through the valve body and the opening after melting, and the solid blocking element will be blocked by the mesh and will not fall off, thereby maintaining the integrity of the blocking element for recycling.

[0031] Five, the fifth point raised in the background art, the valve can not only control the flow between the upper and lower water pipes switch, but also has a full closed position, when the crisis is removed, the valve is switched to the full closed position, which can cut off the water; it can be closed to repair the total valve at night or other reasonable time period after preparation, without immediate, temporary closing of the total valve to cause production and life loss.

[0032] Six, the sixth point raised in the background art, in normal times, the indoor wind environment is controlled by the intelligent curtain wall ventilation system, which can be selected to be used with the curtain wall and horizontal array cold air system, and the opening window position and the cold air outlet and the air volume can be selected to be intelligently controlled based on cfd simulation and optimization analysis, so that the indoor wind heat environment can be reached with the lowest energy consumption. When the fire occurs in the room, the contradiction between the oxygen for breathing, the oxygen for combustion and the toxic smoke diffusion can be balanced by the intelligent control of the opening window.
