Air inlets, key factor in well-being and productivity

In modern swine production ventilation plays a vital role. The effective management of the ventilation may allow to maintain the pig’s health and productivity along with an optimal environment for the animals and farm workers. For the production results and animal wellbeing to happen the fresh air entries have significant impact. It´s the inlets that have the responsibility to make a proper air distribution to all the animals in a room.   

Importance of Inlets in Swine Production

Swine farming projects necessitate meticulous planning, where every component, including inlets, holds significance. Opting for inlets backed by reliable data empowers farmers to make informed decisions tailored to the specific needs of their projects. With detailed information at their disposal, farmers can accurately select and install inlets that contribute to the overall success and efficiency of their facilities.

Understanding Different Types of Inlets

There are 3 main types of air Inlets in the market: wall inlets, ceiling inlets and fresh air chimneys.  Each category has its own characteristics and aspects to be considered.

Wall inlets: Are strategically positioned along the sidewalls of swine facilities to facilitate controlled airflow to the building or from a corridor to the rooms. By allowing fresh air to enter the building while minimizing drafts, wall inlets contribute to maintaining a comfortable environment conducive to the well-being of the animals. The calculation of wall inlets and where to place each unit demands a precise calculation.  The usual selection should consider the desired total air flow, the air throw range and the placing of the equipment to allow even distribution of airflow during all ventilation levels (minimal till maximal) at specific working pressure. Is also important to consider accessories that impact on the equipment and its use.

Ceiling inlets:  Bring air from above the room, using  air from the attic ( pre heated ), to allow even distribution on the air entry to bigger bars or directing air into certain areas. Positioned at the highest point of the facility, attic inlets promote efficient air exchange while minimizing energy consumption.

Chimney Inlets:  Have an important role in swine production. Chimney inlets allow enhanced ventilation efficiency, particularly in larger swine facilities or allowing a specific air flow into compartments and rooms, as well as regions with specific climate considerations. Strategically positioned chimney inlets ensure optimal air distribution and moisture control.

Airflow Dynamics Resulting from Inlets

The airflow resulting from properly functioning inlets is characterized by uniform distribution, minimal drafts, and efficient moisture and temperature control Properly positioned inlets create a balanced airflow pattern, ensuring consistent air quality throughout the facility and mitigating the risk of respiratory issues and heat stress.

Each inlet has its own design and characteristics. Selectin inlets that have a known air flow at each pressure drop, according to the openings, is a differential that allows to properly control the system, since the interaction of the pressure and airflow are extremely important on the inlets.

External factors should be considered as for example wind drafts, if light control is necessary, type of insulation (due to extremes temperature) and construction characteristics. 

Adjusted spacing from inlet to inlet, from barriers and proper installation and construction characteristic are crucial for a good result with the inlets.

Investment

The total cost of the air inlets are calculates with the accessories and necessary equipment’s (as actuators, pulleys, cables ) and the overall cost is a small portion on the investments on the clime control system. Nevertheless, is an important part since it is used constantly. Choosing a solution in air inlets that are capable of creating a good environment with low pressure drop that allow a correct minimum ventilation allow the farmers to reduce cost on heating, electricity for fans .  Managing the system properly result in the reduction of the costs, not just in the environment , it allow also reduction os costs with the animals due to better health and profitability on their performance. 

Summary

In conclusion, inlets play a pivotal role in swine production by regulating airflow, temperature, and moisture levels within facilities. The proper selection, installation, and utilization of inlets are essential for optimizing ventilation efficiency and promoting pig health and productivity. Understanding the different types of inlets and their respective advantages, as well as the airflow dynamics resulting from their operation, is critical for swine producers to make informed decisions and achieve optimal outcomes in their operations. By prioritizing the importance of inlets and adopting best practices in equipment selection and usage, swine producers can enhance ventilation efficiency, minimize production losses, and ultimately optimize their operations for sustained success.
