Project Background and Challenges

This project is located in the production workshop of a professional mold factory in Wenzhou, Zhejiang. Wenzhou is located on the southeast coast of China, with a subtropical maritime monsoon climate. The summer is hot and humid, known as the "furnace", and the hot and humid weather lasts for a long time.

This mold factory mainly serves the locally developed manufacturing industries such as footwear, eyewear, luggage, and lighters in Wenzhou, and develops customized production molds for them. The processing workshop is located in an old-fashioned concrete structure factory building that is relatively old. This type of old factory building generally has the characteristics of high floor height, thin walls, and poor air tightness of doors and windows, which makes it easy for external humid air to enter and difficult to effectively dissipate internal heat.

With the increasing demand for precision in mold processing, high temperature environments not only seriously affect the comfort and work efficiency of operators, but also lead to thermal deformation of machine tools and increased measurement errors of workpieces, directly affecting the accuracy and yield of mold production. Therefore, without carrying out large-scale renovation of old factories, seeking an efficient, flexible, and economical ventilation and cooling solution has become an urgent problem that the enterprise needs to solve.

Ruifeng Plan: Flexible Response, Precise Cooling

In response to the multi variety and small batch mold processing characteristics of the workshop, as well as the limitations of the factory structure, the design team of Ruifeng Environmental Protection Refrigeration abandoned the traditional fixed central air conditioning or large exhaust system after in-depth on-site investigation and innovatively proposed a comprehensive layout plan of "mobile centrifugal air cooler+mobile industrial grade large fan".

The core design concept is as follows:

1. To cope with the flexible layout of "non fixed workstations": Due to the wide variety of molds processed and the heavy weight of raw materials, the workshop adopts a "multi workbench" layout mode. Workers need to work between different workstations, resulting in a high degree of uncertainty in the workstations. The value of mobile devices is highlighted at this moment: they do not require the installation of pipelines or wiring, and can be flexibly pushed to any area that needs cooling according to changes in production tasks, achieving the ultimate flexibility of "equipment follows people, wind follows workstations".

2. Equipment selection for adapting to "open spaces": In response to the poor sealing of old factory buildings and their unsuitability for overall enclosed space cooling, the plan selected a combination of local cooling equipment:

1) Mobile centrifugal air cooler (environmentally friendly air conditioner): Using the natural physical principle of "water evaporation absorbs heat", the hot air is filtered and cooled by a moist water curtain, and then transformed into fresh and clean cold air and sent into the work area. Compared to traditional air conditioning, it can effectively reduce temperature locally in large spaces (usually by 4-10 ℃), while introducing a large amount of fresh air to solve the stuffiness of enclosed workshops.

2) Mobile industrial grade permanent magnet infinitely variable speed large fan: With blades over 1 meter in diameter, aerodynamic design creates a large three-dimensional natural wind field through gentle breeze blowing. This type of wind can promote the evaporation of sweat from the human body, take away body heat, and make employees feel the coolness of "natural wind". Its permanent magnet stepless speed regulation technology ensures silent, energy-saving, and wind speed free operation under different requirements.

The effectiveness and value of the plan

After the implementation of the project, the working environment in the workshop has made a qualitative leap:

1. Significant improvement in physical comfort: The strong 'natural wind' covers the entire work area, effectively dispelling the stuffiness caused by equipment operation and high temperature weather. Employees are no longer restless due to high temperatures, and their work focus is significantly improved.

2. Production quality is guaranteed: the improvement of workshop temperature and air circulation helps reduce thermal deformation caused by temperature differences during precision machining, indirectly improving the machining accuracy and product consistency of the mold.

3. Zero installation, plug and play: No installation work is required after the device arrives, plug and play. For idle workstations, the equipment can be removed at any time without affecting the material flow and equipment layout in the workshop.

4. Extremely low operating costs: using physical cooling instead of compressor cooling, with extremely low power consumption (only about 1/8 of traditional air conditioning). This low investment, high return approach provides strong support for the business philosophy of "saving money is making money".

Regarding Ruifeng

The successful renovation of the machining workshop in the mold factory once again proves that Ruifeng Environmental Protection Refrigeration has the professional ability to select comprehensive equipment and design solutions when dealing with special spaces (such as old factories, irregular buildings) and special usage scenarios (such as unstable workstations and the need for local cooling). Whether it's mold processing, mechanical manufacturing, or other open or semi open spaces with high temperatures, stuffiness, and odor challenges, we can tailor the most economical and effective ventilation and cooling solutions for you, helping enterprises create a healthy, comfortable, and efficient production environment.
