Livestock farm environmental control is based on the growth needs of animals, to provide comfortable temperature and ventilation for animals, while discharging harmful air in the house (such as ammonia, carbon dioxide, hydrogen sulfide and other common harmful gases in pig houses), moisture, dust, there are often viruses in the air that are at greater risk of disease in livestock farms, which is often the focus of farm environmental control. By ensuring the uniformity of temperature and ventilation, effectively reducing the impact of cold stress or heat stress caused by uneven temperature and ventilation or large temperature changes on animals, improving the welfare and health level of animal groups, ensuring the highest digestibility and utilization rate of feed, thereby improving the growth rate of animal groups and improving production efficiency. Farm ventilation and cooling ventilation is a very necessary task and an important part of the work to control the farm environment. The lack of ventilation of the farm is not simply to regulate the temperature and relative humidity of the farm, but also to improve the air quality in the farm, control the occurrence of diseases and other aspects of the important role, the reasonable layout of the farm construction is quite important. All affect the growth and development of animals!

Requirements analysis

Due to the importance of ventilation to animal growth, a series of effective measures should be taken in the animal breeding process to improve the effect of ventilation. First of all, to create a good ventilation environment, the farm should install good ventilation facilities and equipment, which is conducive to ventilation. Adopt an appropriate ventilation mode according to the actual situation. The ventilation modes commonly used in the production of farms mainly include natural ventilation, forced ventilation and cooling water curtains of negative pressure fans, water-cooled environmental protection air conditioning and forced ventilation of negative pressure fans. Natural ventilation is usually available when the farm area is small, the feeding density is low, the day age of the animals is small, and the ventilation method is commonly used in the season when the temperature is low; Forced ventilation is suitable for farms with large areas, higher feeding areas, and larger daily age of animals; The combination of spray nebulizers, cooling water curtains or water-cooled environmentally friendly air conditioners and forced ventilation of negative pressure fans is the main way to cool down in summer. In the ventilation must be carried out according to the actual situation of the field, in order to achieve the best ventilation effect. Continuous ventilation - cooling is mainly used for summer cooling ventilation, according to the different environment of each farm, combined with the actual situation of the farm site, you can choose to use negative pressure fan + cooling wet curtain negative pressure ventilation cooling system or negative pressure fan + water-cooled environmental protection air conditioning positive pressure supply air ventilation cooling system or negative pressure fan + spray atomizer system equipment.

Solution 1: Negative pressure fan + cooling wet curtain negative pressure ventilation and cooling system solution, the main equipment includes negative pressure fan, evaporation cooling wet curtain, water circulation system, artificial intelligence environmental control system, etc.

Solution Description:

Negative pressure fan, evaporative cooling environmental protection air conditioning unit cooling principle: negative pressure fan + cooling wet curtain negative pressure ventilation cooling system scheme is suitable for the farm relatively good sealing of the need for overall ventilation and cooling places, mainly through the negative pressure fan will be the farm in the hot air, harmful air (such as ammonia, carbon dioxide, hydrogen sulfide and other common harmful gases in the farm), moisture, dust forced out of the outdoor, in the case of negative pressure fan exhaust, Indoor negative pressure state, forcing outdoor air through the wet curtain, because the water vapor pressure on the surface of the wet curtain is greater than the pressure of unsaturated air water vapor, so the water on the surface of the wet curtain is evaporated, absorbing a large amount of sensible heat, resulting in a decrease in the temperature of the dry bulbs of the air entering the farm, thereby creating a cool and comfortable ventilation environment.

Solution two: evaporation cooling water cooling environmental protection air conditioning positive pressure supply air ventilation cooling scheme, the main equipment includes negative pressure fan, evaporation cooling water cooling environmental protection air conditioning, water circulation system, artificial intelligence environmental control system, etc.
