Description
Technical field
The present invention relates to VMC (Ventilation Mechanical Control System), particularly a kind of severe cold and cold district scale pig house VMC (Ventilation Mechanical Control System) in winter.
Background technology
Along with pig industry is intensive, the improving constantly of large-scale degree, health and air pleasant degree in pig house require also
Improve constantly.The especially scale pig house of severe cold and cold district, winter temperature decline can make the growth performance of pig reduce,
Affect economic benefit, need pig house is carried out heating and insulation.Meanwhile, in order to reduce winter heating energy consumption, closing is generally used
The way of door and window.Due to factors such as fecaluria accumulation, the fermentation of feedstuff pad grass, corrupt decomposition, mix substantial amounts of in airtight pig house can be made
The toxic and harmful such as ammonia, hydrogen sulfide.Pig can be caused to produce bronchitis, pneumonia etc. exhale when harmful gas concentration is too high
Inhale tract disease, cause heavy economic losses to Swine Production.Therefore, pig house must be fed new wind in the winter time, harmful to reduce
Gas concentration, in making pig house, be up to state standards air quality (with CO2 concentration for indicating) health level required.
At present, Chinese large-sized is raised pigs especially state-owned enterprise of enterprise, mostly uses in the construction operation of scale pig house
The supporting technology of the north america such as the U.S., Canada.The air vent mode of pig house building is: do not set fresh air pipeline in house, outside side
Air-introduced machine installed by wall, and new wind entrance is open cornice, uses wind pushing form under furred ceiling air port.This winter ventilation mode is brought
Problem be: (1) needs bigger building floor height to install furred ceiling, utilizes the space above cornice and furred ceiling to form new wind in winter
Air intake passage.Due to the difference of domestic and international price of steel product, furred ceiling is installed and makes the building cost of China's pig house dramatically increase.(2)
Owing to cornice is the most unlimited, the Insulation of roofing lost efficacy, and needs to be incubated furred ceiling, not only increases construction cost, also
Substantially reducing the seal of pig house, make heating energy consumption increase, operating cost improves.(3) for ease of construction, air port is on furred ceiling
It it is the most equidistantly distribution.Owing to blower fan is positioned at side wall, from each air port apart from different, cause each air outlet air quantity uneven,
Resh air requirement is relatively big at the blower fan, and resh air requirement is less in the middle part of pig house and at offside exterior wall.The distribution of this new wind is unfavorable for
Form temperature field in house stable, uniform, thus affect the growth performance of pig.
The new wind pattern in winter of existing furred ceiling+cornice air-supply reduces the seal of pig house, causes heating energy consumption to increase, fortune
Row expense strengthens；She Neixin wind skewness, and thus produce uneven temperature field, local temperature is too low；Arrange band to open wide
The summer that the furred ceiling of cornice is applicable to temperature district higher, south is heat insulation, is unfavorable for Winter protection, adds construction investment simultaneously.
Therefore, its improve and innovate imperative.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the purpose of the present invention is just to provide a kind of severe cold and cold
Area scale pig house VMC (Ventilation Mechanical Control System) in winter, can effectively solve pig house and ventilate and the problem of Winter protection.
The technical scheme that the present invention solves is that, including pig house, pig house is to be blocked up by along the two of the alternate layout of pig house long axis direction
Vertical wall, it is symmetricly set on the cross wall (also known as gable) at vertical wall two ends along pig house short-axis direction and is arranged on vertical wall, cross wall top
The hollow structure that roof (ceiling) is constituted, in pig house, top is provided with fresh air pipeline along pig house long axis direction, and fresh air pipeline is
The rectangular hollow structure of both ends open, the opening at two ends is located at the cross wall top of respective side as air inlet, two air inlet end-rack
And the perforation on cross wall and pig house be connected externally to lead to, have multiple wind pushing hole before and after fresh air pipeline on two sides, two block up
It is respectively arranged with blower fan on vertical wall.
Present configuration novelty is unique, and advantages of simple easily produces, low cost, increases the seal of pig house, reduces north pig
The winter heating heat consumption of house；Velocity field and the temperature field of stable and uniform is formed in pig house；Reduce cost, disappear with the less energy
Consumption and material consumption reach more preferable heating, heat insulation effect, are the innovations on pig house ventilation warming system.

When the present invention uses, opening blower fan 1, new wind enters in the body of fresh air pipeline from the two ends of fresh air pipeline, then from
Wind pushing hole enters inside pig house, compared with prior art, the invention have the advantages that
1. installing fresh air pipeline in pig house, airduct is arranged in indoor roof (ceiling) lower section, uses 25mm thickness PVC
Plate, light weight is inexpensive, it is easy to purchases, transport, and rectangular duct is prone to manufacture, assemble, it is not necessary to separately set furred ceiling, reduces building height and makes
Valency；
2. size and the spacing in airduct sidewall air supply hole obtains according to applicant's repetition test, thus wind needed for reaching pig house
Amount and wind speed, use centrosymmetry mode, reach the purpose of balanced ventilation；
3. airduct two ends are air inlet, and wind pushing hole is positioned at the position that airduct two sides are top, compared with air-supply under furred ceiling side,
Being possible not only to make the peripheral structure of pig house keep preferable seal, new wind in winter (outdoor cold wind) is under arriving pig house simultaneously
Can have with Indoor Thermal air before portion and preferably mix, it is to avoid cold wind directly blows to pig zone of action；
4. for preventing rain, snow from invading airduct, airduct base plate need to have certain gradient towards air inlet when installing, and in two
End air inlet is installed sparrow prevention net and is entered with protection against rodents, passeris montani saturati.
The present invention through repetition test, all obtain same or like as result, test to center, air outlet (wind in pig house
Fan) it is respectively provided with monitoring point at the inside 1m in upright position 0.5 meter of place on the ground and 0.5 meter, the inside 1m in air inlet upright position ground,
By the result of data that collects as shown in Figure 7,8, by result of the test it should be apparent that:
Under the conditions of identical building size, the pig house that initial temperature is identical, after 20-30 minute, temperature reaches stable, this
Bright air supply mode not only temperature in pig fowl behaviour area is higher 2-3 DEG C than furred ceiling air-supply, it is often more important that animal house diverse location energy
Enough obtaining more uniform temperature distribution, the present invention increases the seal of pig house, reduces the winter heating heat consumption of north pig house；Pig
Velocity field and the temperature field of stable and uniform is formed in house；Reduce cost, reach more preferable with less energy resource consumption and material consumption
Heating, heat insulation effect, easy to use, effective, have good Social and economic benef@.
