As a modern large-scale breeding base, Chen'an Pig Farm faces significant challenges from high temperature and humidity during summer, which adversely affect swine health. To create a comfortable and healthy breeding environment, Nantong Yueneng Energy Saving Purification Equipment Co., Ltd. leveraged its professional expertise and patented products to design a customized high-efficiency ventilation and cooling system for the farm. The system integrates FRP corrosion-resistant negative pressure fans (livestock exhaust fans), internal circulation evaporative cooling pad walls, and high-efficiency sidewall ventilation windows. Through scientific airflow organization and energy-saving technologies, it enables precise environmental control within the pig houses, thereby enhancing breeding efficiency.

Technical Features:
The housing is constructed from corrosion-resistant FRP material, offering resistance to acid and alkali corrosion, making it suitable for high-humidity and high-ammonia environments in breeding farms, thereby extending equipment service life.
The fan blades are made of cast aluminum, aerodynamically optimized with scientifically calibrated angles and curvature to achieve high airflow volume and low energy consumption, ensuring efficient air exchange.
Converging-Duct Design: The innovative converging-duct structure features a streamlined airflow passage that reduces wind resistance and enhances air collection efficiency. This design increases airflow volume by 10% compared to conventional fans, extending ventilation coverage and exhaust capacity.
Structural Advantages: The integrated molding of the fan frame and blades ensures structural stability, while facilitating easy installation and maintenance across various application scenarios.
Components: Comprises high-efficiency evaporative cooling pads, aluminum alloy frames, PVC elevated base water tanks, and a water circulation system.
High-Efficiency Evaporative Cooling Pads: Featuring a honeycomb porous structure with 7mm wave height and 45° staggered opposing, these pads form a dense water film surface to ensure optimal air-water contact. They exhibit high water absorbency, mold resistance, and corrosion resistance. The 15cm thickness of the cooling pad wall enhances cooling performance.
Frame: The base tank (water reservoir) is made of corrosion-resistant PVC with an elevated design for increased water storage capacity. Other frame components are constructed from aluminum alloy, suitable for high-temperature, high-humidity, and corrosive environments in breeding farms.
Water Circulation System: Includes submersible pumps, spray pipelines, and an intelligent water level control system. A float valve automatically regulates water levels to ensure consistent and uniform wetting of the cooling pads, minimizing water waste.
Working Principle: Operation of the exhaust fans creates negative pressure, drawing outdoor air through the evaporative cooling pads where water evaporation absorbs heat, thereby cooling and humidifying the air. Combined with the sealed pig house structure, this facilitates internal air circulation, rapidly expelling polluted air and maintaining fresh indoor conditions.

Functional Design: Constructed from ABS material, these ventilation windows are corrosion-resistant and anti-aging. Equipped with automatic flap or adjustment mechanisms, they utilize the pressure difference between indoor and outdoor environments to automatically open or close the louvers, enabling airflow regulation and temperature control.
Automatic Sensing Operation: When negative pressure increases indoors (e.g., during fan operation), the louvers automatically open outward; they close when pressure normalizes, requiring no manual intervention.
Air Guidance and Cooling: The louver structure directs airflow to prevent direct drafts on the animals, while synergizing with systems like evaporative cooling pads for effective temperature reduction.
Durability and Maintenance: Made from engineering-grade ABS plastic, these windows resist aging and corrosion, suit high-humidity and high-ammonia conditions, and are easy to clean.

High-Efficiency Cooling: The evaporative cooling pad wall achieves over 80% cooling efficiency. Combined with the high airflow delivery of FRP exhaust fans, it reduces indoor temperatures by 5–12°C in summer, delivering significant cooling effects.
Corrosion Resistance and Longevity: The system employs corrosion-resistant materials throughout, adapting to harsh farm environments and extending equipment lifespan by over 30%.
Environmental Sustainability: The evaporative cooling pad wall utilizes a recirculating water system, reducing water consumption.
Customized Adaptation: Equipment placement and quantity are flexibly designed based on pig house scale, layout, and climatic conditions to ensure optimal ventilation and cooling performance.
The ventilation and cooling system provided by Nantong Yueneng has established an optimal breeding environment for Chen'an Pig Farm. It effectively mitigates heat stress risks in swine, improves feed conversion rates and growth performance, and reduces the likelihood of disease transmission. This initiative supports the farm in achieving green, efficient, and sustainable operations.
