Description

Inner ventilation system for livestock barn}

The present invention relates to a ventilation system, and more particularly to a barn internal ventilation system for driving a ventilation fan for internal circulation of the barn raising livestock, such as laying hens, broilers, ducks, cattle, pigs.

The house is equipped with a ventilation fan for supplying air to supply fresh outside air to the house, and an exhaust fan for discharging the contaminated air to the outside, and constitutes a house ventilation system. There are further small fan circulation fans.

The main purpose of using the air circulation fan is to create additional airflow inside the house.

In general, in the cold season, the use of the supply air ventilation fan and the exhaust ventilation fan connected to the outside of the house is minimized. At this time, there is not enough power to generate the air flow inside the house and the house air flow is stagnated. In addition, at this time, the relatively warm air is gathered up than the height of the livestock breeding due to buoyancy, and the actual temperature of the livestock breeding space is relatively low.

Therefore, by operating the above-described internal circulation ventilation fan to remove the separated layers of cold air and hot air in the livestock house, it is possible to efficiently use the heat energy in the upper part of the livestock house.

In addition, in the cold season, in order to lower the body temperature of the livestock, a high flow rate of air must be made. In this case, the airflow formed by operating the air circulation fan as well as the ventilation fan for the air supply and the exhaust fan connected to the outside of the barn is high temperature. It will play a big role in relieving the stress of livestock.

In addition, when operating the tunnel-type ventilation system in which the exhaust ventilation fan is concentrated in the longitudinal rear of the building for a high flow rate, if the length of the building is too long compared to the capacity of the exhaust ventilation fan, the longitudinal pressure gradient By this, sufficient ventilation performance may not be exerted. In this case, when the ventilation fan for the bet circulation is installed and operated at an intermediate point in the longitudinal direction, such a pressure gradient is eliminated, and a tunnel-type ventilation airflow can be smoothly formed inside the barn, By reducing the electrical energy can be used efficiently.

The ventilation fan for the internal circulation of the house is usually driven in a manner of repeating on-off according to a predetermined driving time schedule without continuously driving.

In addition, if the above-mentioned circulating ventilation fan is additionally used in a barn with a ventilation system including an air supply fan and an exhaust fan, the livestock farm is separate from the livestock raising. There is a problem that the burden on the electricity bill of the ventilation system increases.

Referring to FIG. 1, the house internal ventilation system 100 according to the present invention includes an exhaust fan 110 for exhaust, a wind power generator 120, a storage battery 130, and an internal air circulation controller 140.

At least one exhaust fan 110 for exhaust is installed in the livestock house.

The wind generator 120 is installed outside the barn at least one corresponding to the exhaust ventilation fan 110 one-to-one.

The wind generator 120 generates electrical energy by utilizing the exhaust flow of the exhaust ventilation fan 110 as a wind power source, as shown in Figure 2 in front of the exhaust ventilation fan 110 outside the barn. It is disposed at a position separated by a predetermined distance to utilize the exhaust flow of the exhaust ventilation fan 110 as a wind power source.

The wind generator 120 is a generator 122 and the generator for converting the rotational energy of the wing portion 121 and the wing portion 121 rotated by the exhaust flow of the exhaust fan for exhaust 110 to electrical energy. It is configured to include a tower 123 for receiving and fixing (122).

The wing portion 121 is preferably configured to include a plurality of (preferably three) wings 121_1 and a wing protection frame 121-2 for protecting the wings 121_1.

It is preferable to use a coreless generator that can be miniaturized as the generator 122.

At least one surface of the tower 123 of the wind power generator 120 forms a translucent surface or a transparent surface, and the internal LED lamp that is turned on by the electric energy generated by the generator 122 through the translucent surface or the transparent surface. The light of 123_1 may be emitted to the outside.

At least one internal LED lamp 123_1 of the tower 123 may be turned on only while the generator 122 is operated, or may be turned on by electric energy supplied from the battery 130. Lighting control may be controlled by the bet circulation controller 140.

When the internal LED light 123_1 of the tower 123 is turned on, the aesthetics around the barn can be improved at night, and in particular, the tower 123 may serve as a boundary light for mountain animals appearing around the barn at night.

As shown in FIG. 3, the wind generator 120 may be used in a state in which a plurality of wind generators 120 are connected by a fence.

As shown in FIG. 4, the wind generator 120 may be manufactured and used in a shape in which the wing parts 121 are arranged in two rows.

On the other hand, as shown in Figure 5, the exhaust flow of the exhaust ventilation fan 110 is supplied to the wind power generator 120 as a wind power source compared with the natural air flow (see (a) of Figure 5), The wind distribution state (refer FIG. 5 (b)) in which air flow is reduced in the central axis part of the exhaust fan 110 for exhaust is shown.

In view of the wind distribution state of the exhaust flow of the exhaust ventilation fan 110, the inventors conducted an experiment to determine the most suitable arrangement position for using the exhaust flow of the exhaust ventilation fan 110 as a wind power source. Was performed.

For reference, the graph shown in FIGS. 6 to 9 shows the wind generator 120 when the wind generator 120 is disposed at a position separated by a predetermined distance in front of the exhaust ventilation fan 110 outside the barn as shown in FIG. 2. Experimental results for determining the most suitable arrangement position to use the exhaust stream of the exhaust ventilation fan 110 as a wind source.

The exhaust ventilation fan 110 used for the experiment is a 50-inch exhaust ventilation fan mainly used in livestock farms. The size of the exhaust fan is about 137 cm x 137 cm, and the vertical length of the fan is 68.5 cm from the center of the fan. The fan was installed at a remote height.

The anemometer used in the experiment measured the exhaust flow at the point 0.5m to 10m away from the central axis of the exhaust ventilation fan 110 during the operation of the exhaust ventilation fan 110.

During the experiment, the exhaust stream of the exhaust ventilation fan 110 extends about 10 to 20 cm from the fan and is divided into a case in which there is no exhaust stream collecting duct which causes the exhaust streams to be collected in the center without being scattered to the side. The wind speed was measured.

During the experiment, the exhaust fan (1100 operating current of 60Hz, 50Hz, 40Hz was adjusted to adjust the wind speed.

FIG. 6 is a graph showing a wind speed distribution according to a flow rate measured by placing the anemometer on the same line as the central axis of the exhaust ventilation fan 110 when the exhaust ventilation fan 110 has no exhaust flow focusing duct.

Referring to FIG. 6, it can be seen that at 40 and 50 Hz, the maximum wind speed appears in a very small area with one point where the maximum wind speed appears. On the other hand, at 60Hz, the wind speed is high at a distance of 1 to 3m. The distance at which the maximum wind speed appears is formed at a point closer to the exhaust ventilation fan 110 as the flow rate of the exhaust ventilation fan 110 decreases, that is, the lower the required current, and conversely, the flow rate of the exhaust ventilation fan 110 increases. As the distance increased, the zone formed at the far point and the maximum wind speed increased. When the wind speed reached the maximum wind speed, thereafter, there was a linear decrease of the wind speed as a whole, and at a distance of more than 3m, the wind speed also slowed down. In the 3m point where the wind speed decreases and then gradually decreases, 60Hz is reduced to 2.52m / s and 50Hz is 3.16m / s, which is higher than 60Hz. At 40Hz, the wind speed tended to decrease to 1.12m / s.

7 is a graph showing a wind speed distribution according to the flow rate measured when the exhaust ventilation fan 110 has an exhaust flow focusing duct on the same line as the central axis of the exhaust ventilation fan 110.

Referring to FIG. 7, the section in which the maximum wind velocity occurs only at 40 Hz was shorter than in the case where there is no exhaust flow converging duct, as shown in the experimental result of FIG. 6. As in the case of the non-projecting structure, the wind effect was minimal at 2 m or more. In the test conditions of 50 and 60Hz, the wind was strong at the point of 1 ~ 2m, and when the wind was decreased, the wind speed decreased to 3m / s without the protrusion structure, while the wind speed decreased to about 3.7m / s. After falling, it began to slowly decrease. The maximum wind speed at 60Hz was 6.27m / s and the maximum wind speed at 50Hz was 5.44m / s at 2m away, and the maximum wind speed at 40Hz was 5.93m / s at 1m away. The maximum wind speed was the same as the case without the exhaust flow converging duct as shown in the experimental results of FIG. 6, but the maximum wind speed decreased at 60 and 50 Hz, but the maximum wind speed increased at 0.55 m / s at 40 Hz. there was.

FIG. 8 is a graph illustrating a wind speed distribution according to a flow rate measured by leaving an anemometer at a left side of 1 m from a central axis of an exhaust ventilation fan 110 when there is no exhaust flow converging duct in the exhaust ventilation fan 110.

Referring to FIG. 8, when the anemometers are installed in a line from the center of the exhaust ventilation fan 110 as shown in FIG. 6 and FIG. In other cases, different results were shown. It increased rapidly from 1m and showed maximum wind speed near 3 ~ 4m, and the wind speed tended to be slower than the result measured from the center line of the fan. It is thought that wind speed influences from 3 to 5m in general. The maximum wind speed was considerably reduced compared to the points on the center line of the fan, showing a maximum wind speed at 4 meters away. It was found that the flow rate of the exhaust ventilation fan 110 was slightly increased to 2.29 m / s at 60 Hz and 2.45 m / s at 50 Hz, but the maximum wind speed was 1.39 m / s at 40 Hz.

9 is a graph showing the wind speed distribution with the anemometer left 1m from the central axis of the exhaust ventilation fan 110 when the exhaust ventilation fan 110 has an exhaust flow focusing duct.

Referring to FIG. 9, it could be confirmed that the distance from which the wind gathers is generally far away due to the influence of the exhaust flow focusing duct. The maximum wind speed was 2.68m / s at 60Hz, 2.37m / s at 50Hz, and 1.76m / s at 40Hz at 4m. The maximum wind velocity at 60 Hz and 40 Hz tended to increase slightly compared to the absence of the exhaust flow concentrating duct, but there was no significant difference at 50 Hz. In addition, it can be seen that the wind tends to decrease more slowly after the maximum wind speed due to the influence of the exhaust flow focusing duct.

Based on the experimental results of FIGS. 6 to 9, in the present invention, the wind power generator 120 is exhausted in a width range of less than 1 m to the left and less than 1 m to the right from the central axis of the exhaust ventilation fan 110. It is preferable to be disposed in the front range of 1 to 3m from the central axis of the ventilation fan 110, so that the wind power generator 120 can utilize the exhaust flow of the exhaust ventilation fan 110 as a stable wind source. do.
