Guangzhou is located in the subtropical monsoon climate zone, with high temperatures and humidity throughout the year, especially in summer. The high temperature and humidity environment pose a challenge to both humans and animals. The dairy farm's milk production center is located in the outskirts of Guangzhou and is responsible for providing fresh milk to the surrounding residents. The health status of cows is directly related to milk production and quality, and the comfort of the breeding environment is one of the key factors affecting the health of cows. Research has shown that cows can increase milk production by more than 10% under suitable temperature and ventilation conditions. Therefore, improving the breeding environment is not only a need to increase production capacity, but also a responsibility to ensure that citizens can drink high-quality and fresh milk.

The building structure of the milk production center is relatively transparent, but due to the lack of effective ventilation and cooling facilities, the interior is hot and humid during the high temperature period in summer, and cows are prone to heat stress reactions, which affect feeding and milk production. To address this challenge, the design team of Ruifeng Environmental Protection Refrigeration conducted in-depth on-site research, taking into account various factors such as the climate characteristics of Guangzhou, the special needs of the aquaculture industry, and equipment investment costs. Finally, a flexible, economical, and efficient ventilation and cooling solution was proposed, which combines multiple mobile centrifugal air coolers with mobile industrial grade large fans.

The rationality of this design concept is reflected in the following aspects:

1. Flexible response to changes in breeding scale: There is uncertainty in the quantity of dairy farming, and traditional fixed installation equipment is difficult to adapt to this dynamic change. Mobile models do not require fixed installation and can be flexibly arranged according to actual needs, truly achieving "ready to use, ready to move" and greatly improving equipment utilization.

2. Adapting to the local cooling needs of open environments: The milk production center has a relatively open structure and is not suitable for fully enclosed air conditioning systems. Centrifugal air coolers utilize the principle of "water evaporation cooling" to absorb heat from the air through water evaporation, effectively reducing local environmental temperatures by 3-5 ℃; Industrial grade large fans generate strong "natural wind" through large-diameter blades (over 1 meter), accelerating air flow and taking away surface heat, achieving a dual effect of ventilation and cooling.

3. The principle of physics brings a natural and comfortable experience: the combination of air coolers and fans simulates the synergistic effect of wind and moisture in nature, which not only has a significant cooling effect, but also brings fresh and natural air flow. This' natural wind 'helps reduce the occurrence of respiratory diseases in cows, improve their overall health level, and thus ensure stable milk production and quality.

4. Reducing construction costs and later maintenance difficulties: Mobile devices do not require civil engineering installation, saving the construction costs of a large number of supporting facilities such as pipelines and brackets required for traditional ventilation systems. The equipment itself has low operating costs and simple maintenance, greatly saving the operating expenses of the breeding farm.

After the implementation of the project, the air circulation inside the milk production center has significantly improved, the comfort level of the cows has greatly increased, their feed intake has increased, their emotions have stabilized, and their milk production has increased by about 15% compared to before. The head of the breeding farm stated that the equipment operates quietly and stably, almost without affecting the daily routine of the cows, and the effect exceeds expectations.

Although this is a mobile fan layout solution provided for the milk production center of a dairy farm, the design ideas and technical capabilities behind it are also applicable to various special spaces and usage scenarios such as warehousing and logistics, temporary exhibitions, industrial plants, sports venues, etc. Ruifeng Environmental Protection Refrigeration has the ability to comprehensively select and design solutions for different industries and environments, always adhering to customer needs as the guide, balancing effectiveness and cost, and providing customers with the most practical ventilation and cooling solutions.
