In the hot summer, high temperatures are the most troublesome problem for every large-scale quail farmer. With tens of thousands of quails living densely in the cages, once the temperature exceeds 30℃, the quails will experience a decrease in feed intake, a sharp drop in egg production rate, heat stress and even a large number of deaths, causing huge economic losses to the farmers. Traditional natural ventilation and ordinary exhaust fans have long been unable to cope. How to create a cool, comfortable and clean growth environment for the quails? Nantong Yueneng Energy Saving Purification Equipment Co., Ltd. (hereinafter referred to as "Nantong Yueneng") has provided a professional solution - a customized ventilation and cooling system solution of "negative pressure fan (exhaust fan) + evaporative cooling pad".
Although quails are small in size, their body surface has a relatively large area for heat dissipation, and they are extremely sensitive to environmental temperature. Research shows that the most suitable temperature for laying hens during the laying period is 25℃ to 30℃. When the room temperature is lower than 20℃, the egg production rate will decrease by 10%, and if it is lower than 10℃, it will decrease by 60% or even lead to a shutdown. During the hot summer season, in large-scale breeding farms, a single cage building often houses 10,000 to 20,000 or even tens of thousands of quails. Relying solely on natural ventilation is far from sufficient to meet the cooling needs. What is even more notable is that, simply high temperature is not terrifying. What is truly fatal is the combined effect of "high temperature and high humidity" - in hot and humid weather, the oxygen content in the cage is low, the air pressure is low, and bacteria multiply rapidly, resulting in problems such as decreased egg production, heat death, and frequent diseases in quails.

In response to the pain points of large-scale quail farms, the technical team of Nantong Yueneng Company went deep into the farming field. Considering the structural characteristics of the quail houses, they customized a "vertical ventilation cooling scheme using exhaust fans and evaporative cooling pads". This scheme fully utilizes the principle of negative pressure ventilation. Through scientific layout, it achieves efficient cooling and ventilation throughout the entire house.
Exhaust fan: Yuenengbrand high-efficiency sliding exhaust fan, with a 304 stainless steel frame for rust and corrosion prevention; equipped with a unique centrifugal opening mechanism to ensure the minimum running resistance when the louvers are fully open, and to prevent wind, rain and dust when closed; equipped with a national standard full-copper wire motor, durable and powerful, capable of efficiently extracting heat and odors from the house.
Evaporative cooling pad: Yueneng evaporative cooling pad is manufactured using an advanced automated production line, with uniform waves, high structural strength, strong water absorption capacity, and long service life. Tested by the laboratory of China Agricultural University, its evaporation cooling efficiency is over 80%, free of harmful substances that can cause allergies, green, safe and energy-saving.
Installation layout: Install the Yueneng evaporative cooling pad on one end of the wall of the quail house, and the exhaust fan on the other end. When the fan is activated, a negative pressure is generated inside the house, forcing the outdoor hot air to flow over the moist evaporative cooling pad surface - the moisture evaporates and absorbs a large amount of heat, causing the air passing through the evaporative cooling pad to significantly decrease in temperature, forming a continuous and stable cooling current that continuously enters the house, and then the fan forcibly expels the house's exhaust gas and residual heat, forming a continuous and stable cooling cycle. The entire system can lower the house temperature by 5℃ to 15℃, creating a comfortable and cool growth environment for the quails.

The core advantage of Yueneng's "exhaust fan + evaporative cooling pad" system lies in its adoption of a purely physical evaporation cooling principle. It does not require a compressor or consume chemical refrigerants such as Freon, making it a truly environmentally friendly cooling method. Its working principle is simple and efficient: The water circulation system evenly distributes water on the surface of the evaporative cooling pad, forming a continuous water film; the fan sucks in air, creating a negative pressure difference, driving outdoor air to pass through the evaporative cooling pad at a certain wind speed; when the air flows through the moist porous evaporative cooling pad, water molecules change from liquid to gas, absorbing a large amount of latent heat, significantly reducing the temperature of the air itself - the drier the air, the more obvious the cooling effect. Compared with traditional mechanical air conditioners, the investment cost of Yueneng's evaporative cooling pad fan is only 5% to 30% of that of mechanical air conditioners, and the operating energy consumption is about one-eighth of that of traditional central air conditioning, significantly reducing the electricity burden of the livestock farm.
As a technology-based enterprise that has been deeply engaged in the field of ventilation and cooling for nearly two decades, Nantong Yueneng Energy Saving possesses significant advantages in terms of technical strength and service quality.

This solution has been successfully implemented in multiple large-scale quail farms. The actual operation data shows that in the hot summer weather with an outdoor temperature of over 35℃, the temperature inside the quail houses equipped with Yueneng's "exhaust fans + evaporative cooling pads" system is always maintained at around 28-30℃, the humidity remains within an appropriate range, the quail's feed intake returns to normal levels, the egg production rate significantly increases, and the phenomenon of death caused by heat stress is basically eliminated. Farmers' feedback indicates that after the system was put into operation, not only did the mental state of the quails improve significantly, but the odor such as ammonia in the cages was also greatly reduced, and the overall breeding efficiency was comprehensively enhanced.
In today's era where large-scale quail farming is moving towards refinement and intelligence, scientific environmental control technology has become the core guarantee for the farming efficiency. Nantong Yueneng Energy Saving Purification Equipment Co., Ltd., leveraging its nearly two-decade industry experience, leading technical strength and considerate service system, has specially designed " exhaust fan + evaporative cooling pad " ventilation and cooling solution for quail farms, ensuring that every quail can enjoy a peaceful summer and helping farmers increase production and efficiency.
