Do Evaporative Coolers Work for Cooling Livestock Shelters?

Choosing the Right Evaporative Cooler

When selecting an evaporative cooler for a livestock shelter, consider the size of the space, the number of animals, and the ambient temperature. A general rule of thumb is to choose a cooler that can provide 10-20 square feet of cooled space per ton of cooling capacity. For example, a 1,000 square foot shelter would require a 50-100 ton cooler. Additionally, choose a cooler with a high efficiency rating (e.g., 80-90% or higher) to minimize power consumption and ensure effective cooling.

Designing an Evaporative Cooling System

To ensure effective cooling, design the system to maximize airflow and minimize heat gain. This can be achieved by installing the cooler in a well-ventilated area, using a sufficient number of fans to circulate air, and providing adequate shading to reduce direct sunlight. A good rule of thumb is to install the cooler 2-3 feet off the ground and 1-2 feet away from any obstructions. This will allow for optimal airflow and prevent hot air from being trapped.

Maintenance and Upkeep

To maintain optimal performance, regularly inspect and clean the evaporative cooler’s pads, fans, and condenser coils. Check the pH level of the water and replace the pads as needed (typically every 1-3 years). Also, ensure proper drainage and ventilation to prevent water accumulation and bacterial growth. By following these guidelines, evaporative coolers can provide efficient and effective cooling for livestock shelters in dry climates, reducing the risk of heat stress and improving animal health and comfort.
