Description

Detailed Description of the Invention (Industrial Field of Application) A hot-water animal breeding shed used for raising livestock such as chickens, pigs, and cows, or other warm-blooded animals, especially
An improvement on the one disclosed in Publication No. 34374! 1'?
do.

PRIOR ART A conventional breeding shed of the type described above is substantially defined by two walls, a ceiling and a floor! It has 5111 rooms. The ceiling or side walls close to the ceiling are equipped with ventilation openings, and the side walls close to the floor are equipped with air exhaust [
The air exhaust port is equipped with an air exhaust means such as a fan, which exhausts air from the inside of the room to the outside to create a negative pressure in the room, and uses the negative pressure to draw fresh outside air through the ventilation opening. They are introduced indoors to ventilate the room and make the indoor environment uniform.

In the case of the above-mentioned breeding shed, the air flowing into the room from the ventilation openings provided in the ceiling or side walls moves diagonally within the Y, so it is affected by the interference of gravity caused by the temperature difference in the indoor air, and the air flows into the room. It is very difficult to create a uniform air environment indoors because the uniform movement of air is disturbed and the fresh air introduced from the outside and the indoor air are not sufficiently mixed. Particularly when the amount of air introduced into the room is small, air stagnation occurs in the center of the room. When the indoor air environment becomes uneven in this manner, there is a problem in that the breeding and production activities of animals to be kept indoors are inhibited, and productivity is eventually reduced.

Therefore, the present inventor developed a breeding shed as described in Japanese Patent Publication No. 34374/1983 in order to prevent uneven flow and stagnation of air indoors and create a substantially uniform air environment. .

The breeding shed described in Japanese Patent Publication No. 63-34374 consists of at least 61 m+i, substantially a closed chamber, a plurality of ventilation openings provided in the ceiling spaced apart from each other along the longitudinal direction of the chamber, and a gap between at least one of the two side walls and the ventilation opening; 2. An animal living area defined within the room;
A lower air exhaust stage is provided for discharging air from the chamber to the outside to create a negative pressure in the chamber, and introducing outside air into the chamber through the ventilation [+] from the outside using the negative pressure. shall be.

I like this! When one Li unit is used, the air exhaust means is activated to exhaust air from the room to the outside, thereby creating a negative pressure in the room. Normally, the air temperature inside the hut is always in a lower relationship than the outside air temperature, so the negative If allows relatively low-temperature fresh outside air to flow into the Y through the ventilation openings in the ceiling and by the action of a small force. Introduced vertically downward,! i! ] Flows further downward toward the floor, passing by the side of the living area.

Fresh outside air flowing in direction F towards the floor is deflected by the floor, flows towards the side walls and is deflected upward by the side walls. On the other hand, since the animals housed in the animal living area placed between the vertical line passing through the ventilation opening and at least one side wall are mixed breeds, an updraft is generated in the animal living area. Therefore, the airflow deflected toward the ground by the side wall cooperates with the upward airflow to form a vortex, and thus fresh air from outside flows through the room without locally stagnation.

In addition, there is a ventilation system for poultry houses that is disclosed in Japanese Patent Publication No. 62-9816 and that has recently attracted attention. The left and right cages are arranged symmetrically side by side with a gap, and above the gap, the air Suita 1] is directed downward.
This air outlet 1'' is communicated with an air chamber installed in the attic, and outside air is forcibly supplied into this air chamber by the air outlet Jfill, and the outside air is blown out from the air outlet to the left and right cages. There is a system in which a feed gutter is extended with a gap between the feeders and is tilted forward to provide an air volume of 8I, and the air guide roots are used to guide the feeder laterally.

Zarani, poultry farming 1 disclosed in Jikai 11f162-46143 publication! ! The installed air conditioning system has an air conditioning air outlet installed in the ceiling at an intermediate position where a large number of poultry cage units are placed. , there is one that can be supplied almost evenly from the upper cage to the lower cage.

(Problems to be Solved by the Invention) However, when outside air is introduced into the room by negative pressure, as in the case of the N-stand hut described in Japanese Patent Publication No. 63-34374, when there is a large temperature difference between the inside and outside, Due to the temperature difference between indoor and outdoor air, the flow of outdoor air downward increases, making it difficult to keep the indoor temperature at an ideal temperature for hidden animals.

Also, Japanese Patent Publication No. 62-9816 and Japanese Patent Application Laid-open No. 62-9816
In what was disclosed in Publication No. 46143,! ll
Although an air outlet is provided on the ceiling of one side of the Tagawa cage unit gap or intermediate position, the air is discharged to the outside from an exhaust hole in the wall. Since the effects on animals and the upper air currents generated in animal living areas are not taken into consideration, there is a problem with smooth ventilation indoors.

In addition, the Special Public Interest Publications Act of 1983, which can deal with some of these problems,
In the mixed-breed animal breeding shed described in Publication No. 34374, ventilation is provided at an appropriate temperature under normal climate conditions;
Under summer climate conditions, the ventilation openings for ventilation into the animal living area were located in the center of the room, so there was insufficient ventilation from the side walls, and the temperature inside the room tended to rise. For this reason, more expenses than necessary were required for opening and closing the supply/exhaust means or the ventilation gap.

SUMMARY OF THE INVENTION In order to improve the above-mentioned warm-blooded animal breeding shed, the present invention aims to provide an animal breeding shed in which the direction of ventilation can be changed as necessary to ensure sufficient ventilation in the living area of the room. It is something to do.

(Means for solving the problems) In order to achieve the above object, the animal breeding shed of the present invention has the following features:
I4 The two side walls facing each other and the ceiling,
at least one elongated, substantially rectangular chamber defined by a floor; a plurality of ventilation IMOs provided in the ceiling of said chamber spaced apart from each other along the longitudinal direction of the central portion thereof; , an opening, and a plurality of ventilation openings provided along the longitudinal direction of the chamber in a ceiling portion or side wall F section spaced apart from the one ventilation opening, and the other ventilation opening for allowing ventilation along the side wall; In the vicinity of the ceiling, floor and side walls and between each of the ventilation zones, the warm-blooded animal living area except for the lower area of It is characterized by including a supply/exhaust means for supplying/exhausting air to the mixed-breed animal living area through the ventilation 1fil [TI and the air inlet/outlet 1].

Further, in the above-mentioned mixed-breed animal breeding shed, a shield is provided between the warm-blooded animal living area, the ceiling 1+A3, and the floor to adjust the air flow in this space.

(Function) Under normal climate conditions where the temperature difference between indoors and outdoors is small, the other ventilation opening numbered in the ceiling near the side wall is
When ventilation from the room to the outside begins at the air inlet/outlet using the air supply/exhaust means, the room becomes under negative pressure, and the air temperature inside the nursery room is usually higher than the outside air temperature. Therefore, due to the negative pressure, relatively low-temperature fresh outside air is introduced vertically into the room by the action of gravity through one ventilation opening in the central part of the ceiling, and flows along the mixed-breed animal living area. The water flows towards the floor, while the - part also flows into the mixed animal habitat area. The fresh outside air that reaches the floor is deflected and flows toward the side walls.
It is deflected upward by the side wall to form one ridge. The airflow deflected by the sidewalls is then A vortex is formed in cooperation with the upper air current, and the air is discharged to the outside from the exhaust air 1 through the air supply/exhaust means, allowing ventilation to occur indoors without local stagnation.

In summer climate conditions, -10,000 ventilation surfaces [1
is closed, and the other ventilation surface 1-, which is provided on the ceiling part or upper part of the side wall that is remote from this ventilation opening, is opened, and the indoor air is passed through the air inlet and outlet by the supply and exhaust means to the outside through the exhaust outlet. When the air is discharged and the room becomes under negative pressure,
Fresh outside air is introduced from the other ventilation surface [1,
Similar to the normal situation described above, air flows downwards along the side walls and into the animal habitat. The air flowing downward flows into the animal living area, and when it reaches the floor, it is deflected and flows into the ventilation opening), and the air flows into the animal living area into the animal living area with the generated updraft and the air flowing into the air supply and exhaust means. In cooperation with the airflow from the floor which is deflected as if it were being deflected, a vortex is formed, and fresh outside air flows through the room as in normal conditions, allowing smooth ventilation near the side walls where ventilation is relatively poor. Provides adequate ventilation.

In addition, if a shield is installed between the animal living area and the ceiling to adjust the air flow, it is possible to There is often a sudden flow of water, which can reduce the flow into the animal area and allow more flow along the floor, but the flow is blocked by the shield, so it is difficult to pass through the animal area. The atmosphere to do so will be increased. If an mII body is installed between the ceiling and the ceiling, the flow of air near the floor will be completely blocked, and a large amount of air will not flow near the ceiling, where air flow is easier than in animal living areas. Therefore, uniform flow to the animal living area is possible.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Although not shown in the figure, the longitudinal direction of the building 1 - the end wall 53
Adjacent to it are utility and storage rooms separated from totals 7 and 8 by opaque curtains or walls. The end of the side wall 5 adjacent to the longitudinal end wall of the building 1 is spaced inwardly from the other end wall of the building 1. At both ends of the side wall 5, the two chambers 7 and 8 are connected to each other for ventilation.

As shown in Figures 2 and 4, each chamber 7.8
A rectangular frame 16 forming an air inlet/outlet 60 is provided in a portion of the ceiling 6 corresponding to the raised portion 3' of the roof 3, and this air inlet/outlet 1]60 is located on the longitudinal central axis of each chamber 7.8. It is ranked d. Inside this rectangular frame 16, an air exhaust means, that is, a fan 15 is installed.

Furthermore, as shown in FIG. 8, air exhaust E156 extending in the longitudinal direction of the building 1 may be provided in the ceiling 6 on both sides of the ventilation opening 26.

This air exhaust 1" 56 is a gutter-shaped thing with a cross section "", which is provided so as to open and cover the chamber 7.8 side, and the air in the air exhaust 1" 56 communicates with the inside of the rectangular frame 16. It is connected to the rectangular frame 16 as shown in FIG. The starting parts 3' are distributed substantially evenly in the longitudinal direction of the building 1. In the illustrated embodiment, the center-to-center distance between adjacent ridges 3' is approximately 18.9
m (62 feet), and the distance between the extreme end ridge 3' and the adjacent end of the chamber 7, 8 containing the cage 9 is approximately half of the above-mentioned center-to-center distance. Each ridge 3' is approximately 3.7 m (12 ft) long; each ridge 3'
One end of is approximately 1.5 m (5 neuets) higher than the other end. The raised part 3' is the attic 23 (Fig. 4)
The exhaust space 19 is sealed off against the building 1 and forms an exhaust space 19 which communicates with the outside of the building 1 only through a large window or exhaust opening 20 on one side of the building 1. Cage 9, central passage 10. Ventilation openings 26 and air exhaust [1
56 is arranged symmetrically with respect to a vertical plane passing through the longitudinal center line of the chamber 7.

In addition, as shown in Figures 2 to 4, one ventilation gap l]
Apart from 26, another ventilation opening 58 is provided in the ceiling 6 above the side walls 2 and 5, extending in the longitudinal direction of the building 1, between the ventilation openings 1'' 26 and 5) and sliding doors 59 in 4 ways. rM is adjusted as necessary, taking into account the above.

And, between the ceiling 6 and the animal living area t451.52 and between the floor 11 and the animal living area 51.52, opening 1 dampers 70.71J3 and 80, 81, which are 'a#1 bodies, are respectively installed. They may be provided to block and regulate the air flowing between them.

In the 1q section of each rectangular frame 16, 1lffi insulating doors 17 and 18 are pivotally provided. These doors17.

Sealed against 9. When the fan 15 is activated,
Doors 17 and 18 were blown. As can be seen from FIG. 5, in the case of the fan 15 farther from the exhaust lit day 20, the opening of the door 17 is caused by the cord connected between the cold end of the door 17 and the ridge 3'. 17'. Inside the frame 16 of the fan 15 adjacent to the exhaust fan 120 is an inclined deflection plate 18'.
is fixed and doubles to prevent air blown out by another fan 15 from interfering with the opening operation of the door 18. This deflection plate 18' limits the opening of the door 18, so that in the case of this door 18 -1-
Codes like C 17' are not allowed.

As shown in FIG. 2, one or more fans 15 may be in operation through exhaust openings 20, which may interfere with blackout programs that require darkness during periods of time. To minimize the light incident on chambers 7 and 8, conventional light-trapping panels 21, such as those available from Acta Engineering and Manufacturing, Inc., Oklahoma Mass. Fuji, are used. is used. Such a panel 21 has closely spaced upright blinds 22 of serpentine cross-section, the blinds 22
It is designed to effectively limit the incidence of light without unduly restricting the passage of air between the holes.

As best shown in FIG. 4, an attic 23 above a horizontal ceiling 6 is located on one side of the building 1, between ridges 3' forming an internal exhaust space 19. It communicates with the exterior of the building 1 through a continuous inlet air space 24 formed between the two parallel exterior walls. The outermost wall portion, that is, the r end of the deflection plate 25 is separated from the ground and is connected to the roof 3.
It extends upward towards. In a typical embodiment, the artificial air space 24 is approximately 61α (2 feet) wide and the attic 23 has an average height of 611 (2 feet).

As mentioned above, the ceiling 6 of each room 7.8 has one narrow ventilation space 1] 26 extending in the longitudinal direction, which connects the roof 11 and the room 2.
3) along the elongated ceiling 6. They are spaced apart at irregular intervals. The effective opening degree of each ventilation opening 26 is adjusted by sliding a sliding door 27, and as shown in FIGS. It rests on a supported inwardly projecting lip 28. In a typical installation, the ventilation gap 1126 is approximately 33 ctx wide.
(13 inches) and approximately 122 cm (48 inches) in length and spaced approximately 1220 (48 inches) from each other, i.e., spaced as closely as possible, with sliding door 27 fully open. Between adjacent ventilation spaces "12
It is designed not to interfere with 6.

As best shown in FIGS. 3 and 6, one continuous cable 29 is connected near the ceiling 6 to one chamber 7.
extending longitudinally through the building 1 and attached to each sliding door 27 of one of the rooms 7 and then the building 1.
around a pulley 30 provided on the other longitudinal end wall of the chamber 8 and back through the other chamber 8, where the cable 29 is fixed to the respective sliding door 27 of the other chamber 8. At one end wall 53 in the longitudinal direction of the building 1, the cable 29 goes around another boot 931 and extends along the sub-ket 32 which is driven by the motor 33. This motor 33 is operated to slide all the sliding doors 27 at the same time to increase or decrease the effective opening of all the ventilation doors 26 by a certain amount.

For outside temperatures between approximately -23.3°C (-10°) and 26.7°C (80°C below), the operation of the motor 33 that positions the fan 15 and the sliding door 27 at tNJtltl is 8. The suitable temperature for laying eggs for housed egg-laying hens is from about 21.1°C (70”r) to about 26°C. Each fan 15 has a temperature sensor shown schematically at 34 in FIG. When a temperature exceeding a predetermined temperature is detected, the fan 15 corresponding to the temperature sensor 34 is activated, and when a temperature slightly lower than a predetermined temperature is detected, the fan 15 is stopped. In the exemplary embodiment, such a lagoon sensor 34 is operated by a fan 15 as required to maintain the temperature within chambers 7 and 8 at 26.7±0.22°C (80±0.4°C). 1 for each fan
5 is operated separately and independently from the other fans 15. If the sensing device or one or more fans 15 malfunction and a critical temperature is reached, a temperature sensor 35 located centrally in each chamber 7.8 will activate the fans 15. . For egg-laying hens, all fans 1
The emergency temperature to activate 5 is 35°C (below 95°C).

1'l1M of the sliding door 27 is a desired negative pressure, preferably an external pressure, in relation to the operation and non-operation of the fan 15.
A negative pressure of 0.01 to 0.03 inches of water is maintained in chambers 7 and 8.

One way to accomplish this is to use a differential pressure sensor 36, shown schematically in FIG. It is designed to measure the pressure difference between 23 and 23.

The differential pressure sensor 36 controls the motor 33 to open and close the sliding door 27 to maintain the pressure within a desired range. In a representative embodiment, “77
and the pressure in the attic 23 is about 0.2
54 views to 0.762 (0.01 inch 7” I to 0
503 inches), motor 33 is not activated and sliding door 27 is held in its current position. The pressure difference is approximately 0.254 mJR (0.0
1 inch of water column, the motor 33 is activated (begins to close the sliding door 27; 33 is actuated to begin opening the sliding door 27. In the illustrated embodiment, the ends of chambers 7 and 8 are connected in phase for ventilation, so that all the slides The door 27 is moved by the same amount at lljl.In the case of a chamber 7.8 with a length greater than about 137 yyv (450 feet), even if multiple chambers 7.8 have a common attic section 1v23. ,1]

7 and must be operated separately and independently so that each chamber is substantially hermetically sealed. In this case, it is necessary to provide each chamber with a separate differential balancer 36.

The air flow pattern when the sliding door 27 is fully or partially opened is shown by the arrow in the chamber 7 at J3 in FIGS. 3 and 4.

Under normal climatic conditions, the other ventilation opening 58 is closed by a sliding door 59. attic 23
The advantage of keeping the pressure in chambers 7 and 8 lower than the pressure of The jet of air travels substantially straight downwards until it is deflected towards the opposite animal habitat fljia51.
and 52. The jet of air passes under the lowest stage S9 which is spaced upwardly from the floor 11 by a distance of at least about 1 foot.

If the number of tiers is large, the distance between the lowest tier and the floor 11 is increased. The air flow connects the lowest step to the side wall 2.
and 5, then flow upwardly along walls 2 and 5 of S9, before flowing over cage 9 and through bulge 9. On the other hand, since the chickens housed in the animal housing areas W4 51 and 52 are warm-blooded, an upper air current is generated within the animal housing areas 11 and 52.

Therefore, the air flowing upwards along the side walls 2 and 5 forms a vortex in cooperation with its updraft, thus creating a vortex in the chambers 7 and 8.
The fresh outside air injected into the inside is thoroughly mixed with the air inside all 7 and 8 in a turbulent flow state.

The generally circular air flow configuration along the side walls 2 and 5 causes the faeces collected on the top 9' and the floor 11 to dry quickly. Another advantage of the preferred airflow configuration is that as a result of the sharply deflected fresh air jet 11 at the central passage 10, most of the dust and electrostatic particles are not suspended in the air and are It is to be accumulated on the passageway 10.

One of the more important design considerations is that one fan 15
This is how much the sliding door 27 is heard when the driver is driving. Dimensions of one ventilation opening 26,
In particular, the width of the ventilation opening 26 and the extent to which the sliding door 27 is opened is sufficient to allow the fresh air to flow in the desired jet into the chambers 7 and 8 and that the jet flows substantially towards the central passage 10. There must be. It has a width several times smaller than its length and no greater than about half the minimum spacing between opposing steps. By providing a plurality of narrow ventilation openings 26, each separate and spaced apart, the sliding door can be narrowed compared to, for example, if a larger number of such ventilation openings 17Ilrl were provided so that the sliding door could only be slightly heard. The door 27 is sufficiently audible to ensure the desired circular airflow configuration. If the sliding door is opened only slightly by providing multiple ventilations on the same day, the jet will combine with the air in chambers 7 and 8 before reaching the central passage 10, causing the air in chambers 7 and 8 to It was dissipated at the detention center. For a given size and spacing of one ventilation opening 26, the pressure differential range can be 51 knots to obtain the desired airflow configuration. room 7 and 8) f root room 23
If the pressure difference between them is too small, the jets will be dispersed to reach the central passage 10, whereas if the pressure difference is too large, an undesirable uneven cooling will occur in the chambers 7 and 8. I end up.

The raised inlet air space 24 directs air into the roof 13 section 1423 from a position close to the ground, ensuring that the coldest possible air is supplied into the rooms 7 and 8; In the northern hemisphere, the building 1 is preferably oriented so that the human air space 24 is placed on the dark north side. A good upright artificial air space 24 has a sliding door 27
limits the amount of light incident on chambers 7 and 8 when the light is on. The public air space 24 and the exhaust openings 20 are located on both sides of the building 1 to minimize the circulation of ventilated stale indoor air back into the artificial air space 24.

For egg-laying hens, the quantity of fans 15 should be such that when all fans 15 are operating the air circulation ffi is at least 0.142 TrL3 (5 cubic feet) per bird per minute. selected to ensure adequate cooling during warm weather. When trying to maintain an ideal indoor temperature, the temperature should be approximately -23.3℃ (-
For outside temperatures below 10°C, some supplementary heating may be required, and if the outside temperature continues to exceed approximately 29.4°C (85°C), some additional heating may be required. Supplemental cooling can be provided by placing an evaporative cooling pad 40 below the deflection plate 25 in the fresh outside air, as shown in FIG. can.

Further, when the above-mentioned slight cooling cannot be assisted, for example in summer weather conditions, one ventilation opening 26 is completely closed by the sliding door 27, and the other ventilation amount D58 is closed by the sliding door 59. The opening and closing are adjusted as in normal climatic conditions. In such a state-C, the air in the chamber 7.8 is exhausted from the exhaust opening 20 through the air inlet/outlet [160] by the operation of the noan 15.

Due to this. When chamber 7.8 is under negative pressure, a jet of air flows through the side walls 2 and 5 from the other ventilation volume 58, as indicated by the arrow in chamber 8 in FIGS. 3 and 4. Flows between zones 51 and 52, floor 1
1, the animal quarters [51 and 52 and floor 11] are forced to flow towards the central passage 10, passing over cages 9 and 90, Animal habitat 1
It flows upward through the Chuo Road '1 IS10 section between i+t51 and 52. Then, the upward airflow generated in the animal living areas 1451 and 52 flows along the floor 11 and forms a vortex in cooperation with the air flowing up the central passageway 10.
Through the other ventilation opening 58, fresh salmon air is injected into the rooms 7 and 8, and is thoroughly mixed with the indoor air in a turbulent state. In such a ventilation condition, one ventilation opening 26
Compared to the ventilation state according to
When located in the 5th and l+jl- rows, ventilation is performed more internally, and it is possible to sufficiently cope with the weather conditions of the u season.

If there is a large temperature difference between the other ventilation fil [TI 58 and the platform where air is injected from the outside air, the air may flow down the 1 m between the side walls 2 and 5 and the animal habitat areas 51 and 52 at once. Therefore, animal habitation areas 51 and 52
Dampers 70.71 and 80.81, which are opening/closing bodies installed between the roof Pr6113 and the floor 11, are operated to close the above-mentioned problems as shown in FIGS. 3 and 4. For example, even if outside air suddenly flows, the dampers 70 and 80 will cut off the
Animal habitat! 451 and 52 and no longer flows into the central passage 10. And animal residence (-18 area 5
Since the flow between 1 and 52 and the floor 11 is suppressed, the amount of air flowing between the ceiling 6 and the ceiling 6 increases, but this is blocked by the dampers 71J3 and 81.
Sufficient air flow to animal living areas 51 and 52 is provided. Of course, by adjusting the opening and closing of each damper according to the conditions of the chambers 7 and 8, more suitable ventilation adjustment can be made.

A breeding pen for warm-blooded animals according to an embodiment of the invention is suitable for automatic control by an input pin 37 as schematically illustrated in FIG. Separate temperature sensors 34 in each fan 15 are connected to a computer 37 which monitors the humidity in the area near each fan 15. Historically, the monitor 37 monitors the pressure difference and adjusts the sliding door 27 motor 3 accordingly.
3 and also by means of an auxiliary temperature sensor 35 mounted in the center of each chamber 7.8 (monitoring the temperature emergency situation. In addition to the main power supply 38,
In case of an accident with the main power supply 38, an emergency line 39 should be provided for emergency use. If this is not done, given the high density of the animals being reared, there is a risk that the power supply will be cut off for a fairly short period of time, resulting in considerable damage. The computer 37 is capable of controlling the lighting of the building 1 as well as all other automatic devices.

Tests to determine the required position of the sliding door 27 depending on the desired pressure difference between the actual control system and the υ control system can be carried out using an alternative υ control system instead of the actual control system. . The computer 37 is capable of monitoring the zero position of the sliding door 27, as schematically illustrated at 41 in FIG. Motor 33 can be programmed to operate. For example, testing of an embodiment generally corresponding to that illustrated has shown that sliding door 27 is approximately 20 inches wide when one fan 15 is operated.
The fan 15 opens by a progressively larger but substantially constant distance as the fan 15 is activated.
It has been certified.

The control of the sliding door 27 is controlled by the other ventilation opening 58.
Sliding door 59 of 1711 I! 11 can be similarly performed.

Although preferred embodiments of the present invention have been described above, the present invention should not be limited to these embodiments, and various modifications and modifications can be made. For example, although v7 and 8 have been explained as having two chambers, there may be one or three or more chambers, and in the case of one chamber, the central side wall 5 is not necessary; If more than two chambers are provided, the number of central side walls 5 may be increased.

Also, I explained that it was actually purchased secretly, but below the central @ wall 5, a! An opening 1'' portion may be provided above the upper end of =9.

Alternatively, the air outlet may be placed on the ceiling of the center side wall and shared as the empty air cane openings on both sides.

In addition, the ventilation gaps 1'' 26 on the side of each room 7.8 are spaced apart from each other along the longitudinal center line of the ceiling 6.
However, they do not necessarily have to be spaced apart from each other along the longitudinal central axis, but may be arranged along the longitudinal direction of the chamber 7. I'm glad I got it.

Further, although other ventilation openings were provided in the ceiling in the above embodiment, they may be provided in the upper part of each side wall, including the ceiling platform, along the space between the side wall and the animal living area. A hood may be provided to allow air to flow.

Further, the other ventilation opening may be provided with auxiliary means such as an air blower in case the air is insufficiently injected into the room.

In addition, although the above air inlet/outlet has only been described as "air ratio 1" when the indoor pressure is negative, it may of course be used as an air inlet to bring the indoor pressure into a positive pressure state.
Each ventilation opening then functions as an air outlet 1.

(Effects) In the breeding shed for warm-blooded newborns according to the present invention, one ventilation b"ill is provided in the center of the ceiling in the longitudinal direction, and the animal is housed between the vertical line passing through the ventilation opening and the side wall. Because the area is located in the animal habitat area, the relatively low temperature fresh outside air introduced vertically downward into the room by the action of gravity through the ventilation opening does not directly flow into the animal habitat area. Flows down to the floor through the side of the RF.
I, the incoming air is deflected by the floor and flows towards the side wall, by which it is further deflected -C and flows upward.

On the other hand, since the animals housed in the animal living area W4 are of mixed breed, an updraft is generated in the animal living area, and the air deflected by the side wall and flowing in the F direction cooperates with the upper arm and air current. It works to form a vortex, which is combined with the indoor air.

In this way, the outside air introduced into the room flows through the room without being locally stagnated, creating a similar air environment in the room. Under the weather conditions of season q, since the other ventilation opening is provided longitudinally near the side wall of the ceiling, the negative ventilation fftl C+ is closed and the air enters the room from the other ventilation opening. Since the air is injected, ventilation is performed smoothly, and the ventilation is more sufficient than when air is injected from the ventilation opening on the negative side.

Also, if the air is injected along the side wall from the other ventilation opening, a sudden flow of air may occur, but the shield blocks the ventilation between the animal living area and the floor and ceiling. Or, since it can be adjusted, sufficient ventilation can be provided to the animal living area.

Since it is a breeding shed for warm-blooded animals as described above, the growth of indoor animals is promoted under any weather conditions, productivity can be increased, and it is economically advantageous to have a 1q.
The stone has an excellent effect of being washed away.
