Two ways of ventilating the use of livestock wind turbines

There are two ways to use the ventilation of the windmill, which is the local exhaust ventilation and the full dilution ventilation. How does these two ventilation modes work? Today Xiaobian specifically for everyone to introduce.
1. Local exhaust ventilation: Where the pollutant concentration divergence, divergent state is characterized by low pneumatic state, or pollutants to dust, smoke and other substances, the need for livestock fans placed in the air pumping place, enhance the ventilation effect.
2. Fully dilute ventilation
A full dilution of the ventilation system requires several livestock fans continue to smoke outside the clean air, continuous dispersion of the factory dirty, so that the production process of air pollutants evaporation and accumulation, not to reach the risk level or safety level. Therefore, the control method of dilution ventilation is suitable for the general divergence of pasture air pollutants rather than concentrated in several original points of the occasion, but also for local divergence has been scattered to the air after the occasion.

The actual effect of evaporative cooler pad system in rabbit farm

Le 24 mai 2017, 14:59 dans Humeurs 0

I use the negative pressure wet curtain cooler for 3 years, the feeling is good. Here I am in accordance with the results of my use and rabbit breeding friends to share, I hope we can learn from, let our rabbit farming, more scientific and More effective.

Its principle is in a confined space using a larger power exhaust fan to the room to achieve a certain negative pressure, evaporative cooler pads is a very good permeability of the oil paper, above the sprinkler system, so that the wet paper covered with moisture, because the negative pressure The role of aspen evaporative cooler pads moisture will evaporate in the room endothermic, so as to achieve the effect of cooling

My use of the effect is such that the outdoor temperature of 41, and indoor humidity does not exceed 70, the maximum indoor temperature is 26 degrees, that is, my rabbit's temperature is generally not more than 26 degrees, many people will worry about the use of wet curtain So that the humidity of the rabbit is very large, the actual is the extra worry, as long as the outdoor humidity in the normal range, while the indoor do not use the wet curtain when not more than 65, the use of the process is not more than 75 humidity. When the afternoon outside the room temperature dropped to below 29 degrees, we can turn off the wet curtain water, fan run more than half an hour, it will drop the humidity, to the normal range.

Negative pressure wet curtain cooler installation is generally vertical, that is, the wet curtain installed in the longitudinal side, the other side of the installed fan, wet curtain and fan on the rabbit cage can be 20cm or so, the general height of the wet curtain is 1.4--1.8m, the fan diameter is generally 1.1-1.6m. 900 square meters of rabbit homes generally need to install four 1.1m diameter fan, BBB area of ??22-26 square, wet curtain thickness is 15cm, evaporative air cooler can achieve the appropriate cooling effect, if the rabbit room closed very well, indoor Outside the humidity is not very large case, it is best to achieve the effect of outdoor 42 degrees, indoor in the 23-24 degrees.

Many people worry about the power problem, which is not to worry about, the fan power is 4 1.5KW motor, relative to the air conditioning is insignificant, the effect is much better than air conditioning, because the rabbit is the freshest air, humidity is Very suitable. In such an environment, the normal breeding of rabbits is absolutely no problem, the effect of the appetite for the rabbit is almost negligible. But one thing to note is that in the wet curtain from the recent rabbit cage, relying on the side of the wet curtain with wood and other items to block the rabbit cage, so as not to wind too large, the rabbit cold sick. Rabbit wind speed generally do not exceed 0.3m per second, this is very important.

Livestock fan ventilation requirements

Le 8 mai 2017, 17:12 dans Humeurs 0

Animal husbandry fan in the life will be common to its shadow, its main function 
is ventilation, then in different occasions, animal husbandry, ventilation and 
ventilation of the time requirements of what?

1, the general environmental requirements of the number of livestock fans 
ventilation for about 28 hours each time;

2, in crowded places, ventilation time for about 35 hours each time;

3, there are heating equipment production workshop, livestock fan ventilation time 
for 45 hours each time;

4, livestock fan ventilation time in the high temperature and pollution of the 
workshop, for 55 hours each time;

5, in the more humid areas of the number of livestock ventilation ventilation to 
the appropriate increase, and vice versa to the corresponding reduction.
