Revolutionizing Poultry Barn Ventilation: A Comparative Study

Are your birds showing signs of stress around the 20-day mark? Is there a noticeable variation in the performance of your flocks? Are fuel costs spiraling out of control? If you find yourself nodding to any of these issues, it may be time to reconsider your barn’s ventilation setup.

Understanding Conventional Minimum Ventilation

To grasp the underlying issues, let’s first look at how conventional minimum ventilation operates.

In a typical scenario, cold outdoor air enters the barn through wall inlets, often at sub-zero temperatures. Ideally, the configuration of your ventilators and air inlets should create the correct negative pressure needed to achieve the following:

• Direct the cold air along the ceiling,
• Encourage it to mix with warmer air,
• Allow it to gently descend to bird level.

However, in actual barns, various factors can prevent this ideal scenario from happening.

When static pressure is low or inlets are improperly calibrated, the incoming cold air can disrupt the environment too abruptly, mixing with stale, humid air. This leads to condensation, resulting in water droplets falling near the inlets, which can create wet litter and uncomfortable drafts. The consequences of this include:

• Stressed poultry,
• Uneven distribution of birds in the barn,
• Increased susceptibility to health issues.

Furthermore, the warm air exiting the barn carries valuable heat—heat that you’ve already paid for with propane or natural gas.

Introducing Heat Recovery Ventilation

Heat recovery ventilation presents a straightforward yet effective solution. The concept revolves around a heat exchanger that efficiently utilizes the warm, stale air exiting the barn.

In this system, warm, stale air flows through the heat exchanger in one direction, while fresh, cold air enters from outside in the opposite direction. Importantly, these air streams do not mix, allowing heat to transfer without compromising air quality.

During cold months, this means that incoming fresh air can be warmed up before it reaches the birds. Instead of exposing them to frigid air at 0°F, they receive air at a much more comfortable temperature, potentially around 50°F.

The benefits are substantial:

• Birds experience less stress,
• The risk of disease decreases,
• Flock distribution becomes more uniform throughout the barn.

Moreover, by harnessing heat from the outgoing stale air, producers typically observe fuel savings ranging from 50% to 70%. This not only alleviates financial strain but also contributes to a healthier living environment for the poultry.
