Description

[0001] Pre-Ventilation Air Inlet [0002]

The present invention relates to a ventilating apparatus, and more particularly, to a ventilating apparatus for preheating an outside air to ventilate air inside a housing, such as a cattle, a pig, and the like.

Most of the domestic market houses use sound pressure ventilation systems. The sound pressure ventilation system consists of an exhaust fan and an air inlet. At this time, the exhaust fan discharges the contaminated air inside the housing to the outside of the housing, and the inlet of the air inlet introduces the fresh air outside the housing to the inside of the housing with the air pressure lower than that of the outside by the exhaust fan.

Since the temperature outside the house is lower than the lower limit of the livestock, the ventilation is minimized in order to keep the temperature inside the house at the proper temperature.

However, when the cold air outside the house is directly introduced into the house without a separate preheating space inside the house during the minimum ventilation, various problems may occur.

First, the cold air outside the house has a higher density than the warm air inside the house. Therefore, when it is not mixed with the warm air, it flows down to the bottom of the house and causes cold stress .

In addition, if the ventilation is excessively restricted to an adequate ventilation amount in order to minimize the cold stress of the livestock for the above reason, the relative humidity inside the house and the concentration of the harmful gas may become too high, resulting in various negative results.

Therefore, there is a housing designed to pass through a separate preheating space in which an electric heater is arranged to preheat the outside cold air just before the cold air outside the house is introduced into the house, There is also provided a technique of instantaneously heating the space that is introduced into the interior.

However, in the case of the former, only the recently built part of the house is built, so it is practically impossible for the house without additional warm-up space in the design to provide additional warm-up space.

In addition, in the latter case, a very large amount of electrical energy is required to instantaneously heat the air flowing into the housing, and electrical accidents caused by the condensation phenomenon caused by the temperature difference between the inside and outside of the house in winter And it is a tendency not to be used in the field.

In addition, there has been developed a housing heat recovery device that builds separate facilities outside the housing to increase the temperature of the air flowing into the housing using heat energy in the air discharged outside the house, but the initial facility investment and maintenance expenses are required There are not many farmers who use it because of economic problems.

Therefore, it is necessary to develop a mouthpiece to prevent the cold stress of livestock which is economical, safe, and efficient in keeping the internal environment of the house pleasantly in the house using the sound pressure ventilation during winter.

Referring to FIGS. 1 to 7, the axial inlet air preheating ventilator 100 of the present invention is installed in a plurality of ventilation holes formed in the side wall 11 of the housing 10, as shown in FIG. 1, Lt; / RTI >

Specifically, the axial inlet air preheating ventilator 100 includes a duct 110, a first diverging member 120, a first damper 130, a second damper 140, a second diverging member 150, 3 damper 160, opening and closing member 170, and hood 180.

The duct 110 is formed in a shape in which the top and bottom openings are rotated by 90 degrees and communicates with the inner space of the barn 10 through vent holes formed in the side wall 11 of the barn 10, To the interior of the housing 10.

In the present embodiment, for convenience of explanation, the duct 110 is shown as a square tubular shape, but the shape is not limited thereto.

An inflow inlet 114 is formed on the lower surface of the duct 110 so that the inflow of the inside of the enclosure 10 can be introduced into the first outside air inlet 111 to be described later.

Here, a plurality of the air inlet ports 114 may be provided.

In addition, the duct 110 includes a regulating member 115 that regulates the area of the air inlet 114.

The duct 110 provides a mixing space 116 inside the first outside air inlet 111 for mixing the outside air and the inside air of the inside of the house.

Therefore, in the mixing space 116, the outside air and the inside air are mixed and the outside air can be made into a proper temperature and supplied to the inside of the poultry house 10, thereby preventing cold stress of the livestock in winter.

Since the amount of inflow of the inside of the housing 10 flowing into the inside of the duct 110 can be adjusted by adjusting the area of the inside air inlet 114 using the adjusting member 115, It is possible to maximize the amount of the incoming air and increase the mixing ratio with the cool outside air to make the temperature close to the middle temperature or the middle temperature and to flow into the inside of the housing 10.

The first separating member 120 is provided in the duct 110 to form a first outside air inlet 111 and a second outside air inlet 112 through which the outside air flows into the housing 10.

The first damper 130 is disposed inside the first outside air inlet 111 and adjusts the amount of outside air introduced into the housing 10 when the first damper 130 is opened and closed according to the change in the amount of ventilation.

The second damper 140 is disposed inside the second outside air inlet 112 and adjusts the amount of outside air introduced into the housing 10 when the second damper 140 is opened and closed according to the change in the amount of ventilation.

The second dividing member 150 is disposed above the first dividing member 120 and forms a third outside air inlet 113 through which the outside air flows into the housing 10, Is arranged inside the third outside air inlet (113), and adjusts the amount of outside air introduced into the housing (10) while being opened and closed according to the change of the ventilation amount.

The opening and closing member 170 is coupled to each of the first damper 130, the second damper 140 and the third damper 160 so that the first damper 130, the second damper 140, (160).

The opening and closing member 170 may be provided in a spring shape as shown in FIG. 3, or may be provided in a shape of a bow as shown in FIG.

One end of the spring-shaped opening and closing member 170 is coupled to the duct 110 and the other end is coupled to the dampers 130, 140 and 160 to control the opening and closing of the dampers 130, 140 and 160.

When the damper 130 is opened so that the atmospheric pressure inside the housing 10 becomes lower than the external air pressure and the outside air flows into the duct 110 through the duct 110, the opening and closing member 170 relaxes as shown in FIG. 6, When completed, it shrinks and returns the damper 130 to its original position.

Therefore, the opening and closing of the dampers 130, 140, and 160 can be controlled according to the pressure difference between the inside and outside of the housing according to the elastic force of the spring-shaped opening and closing member 170 and the weight of the opening and closing member 190.

For example, by using the spring-like opening-closing member 170 having a high elasticity or the opening-closing member 190 having a heavy weight, the opening / closing member 190 can be set to be opened and closed by a high pressure difference between the inside and the outside. When the opening and closing member 170 or the weight-closing member 190 having a light weight is used, the opening and closing member 190 can be set to be opened and closed by a low pressure difference between the inside and the outside.

The hood 180 is detachably disposed on one side of the duct 110 disposed outside the housing 10 and minimizes adverse influences of the introduced outside air.

Although the axial inlet air preheating ventilator 100 includes the opening and closing member 170 in the present embodiment, the first damper 130, the second damper 140, And the third damper 160 may be manually opened and closed.

For example, in a high temperature such as summer, the dampers 130, 140, and 160 are all removed by the administrator of the house 10 to maximize ventilation.

In addition, the first damper 130 and the second damper 140, except for the third damper 160, are removed from the middle temperature period, such as spring or autumn,

Only the first damper 130 is removed at a low temperature such as in winter so that the ventilation can be minimized.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. It will be possible.
