Abstract

The utility model discloses a resource-saving type natural ventilation power distribution room, wherein the wall bodies of the power distribution room along the east-west direction are of a double-layer structure respectively. Each double-layer wall body comprises an outer wall, an inner wall and a hollow ventilation layer, wherein the upper part of the outer wall and the lower part of the inner wall are respectively provided with a ventilation shutter. The lower parts of the north-south wall bodies of the power distribution room are respectively provided with a plurality of ventilation shutters, and the upper parts of the north-south wall bodies are respectively provided with a fixed window. The roof of the power distribution room is provided with a lighting and air-discharge skylight. According to the technical scheme of the utility model, based on the hollow ventilation principle, the indoor hot air is enabled to flow into the hollow ventilation layer through the ventilation shutters at the lower part of the inner wall. Under the air-draft effect of the hollow ventilation layer, the hot air is quickly discharged out of the power distribution room through the ventilation shutters at the upper part of the outer wall. Meanwhile, based on the principle of the stack effect, the dirty hot air is discharged from indoors through the lighting and air-discharge skylight at the roof of the power distribution room. The outdoor fresh cold air is inhaled into the power distribution room through the ventilation shutters at the lower parts of the north-south wall bodies of the power distribution room.

Description

A resource-saving naturally ventilated power distribution room

technical field

The utility model relates to a resource-saving naturally ventilated power distribution room.

Background technique

The power distribution room is the power supply and control center of various places such as residential areas, factories, and shopping malls. It is generally equipped with transformers, high-voltage, low-voltage and other equipment, all of which are composed of electronic components. Because the equipment generates current and emits heat during use, the temperature of the power distribution room is much higher than the outdoor temperature, especially in summer, the temperature inside the power room is higher. This brings uncertainty to electronic components: on the one hand, there are hidden dangers to the safe operation of the equipment in the electric room, and on the other hand, it also brings inconvenience to the operators on duty. Under the current circumstances, the general distribution network adopts the method of installing an air-conditioning system to cool down, but this method has two defects: one is that it needs to consume electric energy and waste energy; the other is that pollutants may be emitted due to the use of refrigerants, Not environmentally friendly.

Utility model content

In order to overcome the above-mentioned deficiencies in the prior art, the purpose of this utility model is to provide a resource-saving naturally ventilated power distribution room, which adopts effective natural ventilation measures to meet the ventilation and lighting requirements of the power distribution room.

The technical scheme adopted in the utility model is:

A resource-saving naturally ventilated power distribution room, the east and west walls of the power distribution room are double-layer walls, and the double-layer walls include an outer wall, an inner wall, and a hollow ventilation layer with a thickness of 150 mm , wherein the upper part of the outer wall and the lower part of the inner wall are respectively equipped with ventilation shutters; the south and north walls of the power distribution room are respectively equipped with a number of ventilation shutters at the lower part of the wall and fixed windows are installed at the upper part of the wall, wherein the fixed The height of the window from the indoor ground is not less than 2900 mm; the south or north wall is equipped with fire doors, and the roof of the power distribution house is equipped with daylighting and exhaust skylights.

Further, the maximum opening angle of the ventilation louvers is 45 degrees.

Still further, the ventilation shutters are temperature-controlled electric flat ventilation shutters.

Further, the outer wall of the power distribution room is provided with water sprinkling with a width of not less than 600 mm.

Further, stainless steel pipe permeable fences are also installed around the power distribution room.

The beneficial effects of the utility model are: a resource-saving naturally ventilated power distribution room adopted by the utility model, the east and west walls are hollow double-layer walls, and the hot air in the room is The ventilation louvers at the lower part of the inner wall enter the hollow air exchange layer to form a thermal pressure difference. Through the wind-drawing effect of the central control air exchange layer, hot air is quickly discharged from the upper ventilation louvers on the outer wall to the outside. At the same time, using the principle of "chimney effect", the dirty hot air is discharged from the room through the lighting and ventilation skylight on the roof of the power distribution room, while the fresh cold outdoor air is drawn from the south and north of the power distribution room to the ventilation louvers at the lower part of the wall. inhale. The utility model adopts a variety of ventilation measures to achieve the best natural ventilation effect, reduce the cooling cost of the power distribution room, and achieve the purpose of saving resources. In addition, the utility model also takes into account the lighting requirements of the power distribution room, and fixed windows are installed on the upper parts of the south and north walls.

Detailed ways

Referring to Figures 1 to 5, a resource-saving naturally ventilated power distribution room of the present invention, the east and west walls of the power distribution room are double-layer walls 1, and the double-layer walls 1 include external walls , an inner wall and a hollow ventilation layer with a thickness of 150 mm, wherein the upper part of the outer wall and the lower part of the inner wall are respectively equipped with ventilation shutters 2 . The utility model utilizes the principle of hollow ventilation. The hot air in the room enters the hollow ventilation layer from the ventilation louvers 2 at the lower part of the inner wall, and the hot air rises to form a thermal pressure difference. It is quickly discharged to the outside through the ventilation shutters 2 on the upper part of the outer wall.

In the utility model, a number of convective ventilation louvers 2 are installed on the lower part of the south and north walls of the power distribution room, and a daylighting and exhaust skylight 5 is installed on the roof of the power distribution room. Using the principle of "chimney effect", through the distribution room The daylighting and ventilation skylights 5 on the roof of the roof discharge dirty hot air from the room, while the fresh cold outdoor air is sucked in from the south and north of the power distribution room to the ventilation louvers 2 at the lower part of the wall, forming a bottom-up air flow, Continuous circulation takes away hot air from the room.
