A brief introduction to the design of purification HVAC

2025/5/23

In recent years, with the development of the biomedicine and electronic semiconductor industries in China, an increasing number of graduates majoring in HVAC have turned to jobs related to purification HVAC design or construction. This article will briefly introduce the main work contents of the purification HVAC design for everyone, hoping to be helpful to you.
Firstly, purification HVAC design is a key technology to ensure that environmental parameters such as air quality, temperature and humidity in a specific space meet specific requirements. In fields such as medicine, electronics and biotechnology, this kind of design is particularly important because it is directly related to the quality of the product, the stability of the production process and the health of the operators.
Under normal circumstances, a purification HVAC system mainly includes three aspects: air purification, temperature and humidity control, and air flow organization. Air purification is achieved through a multi-stage filtration system, including primary, medium and high-efficiency filters, which can effectively remove dust particles, microorganisms and other pollutants in the air. Temperature and humidity control ensures that the indoor environment fluctuates within the set temperature and humidity range through processing methods such as heating, humidification, and cooling, to meet the requirements of production processes or human comfort. Air flow organization is achieved through reasonable design of supply air, return air and exhaust air to ensure uniform distribution and effective circulation of indoor air, avoiding adverse air flow phenomena such as vortices and dead corners.

In the design of purification HVAC, special attention should be paid to the flexibility and stability of the system. As different production areas may have different requirements for purification levels, the system should have the ability of zonal control and be capable of adjusting parameters such as supply air volume, temperature and humidity according to actual needs. Meanwhile, the system should also have a high degree of stability to ensure that environmental parameters remain stable and are not disturbed by the outside world during long-term operation.

In addition, energy conservation and environmental protection are also important considerations in the design of purification HVAC. By adopting highly efficient and energy-saving equipment and advanced control technologies, the energy consumption and operating costs of the system can be reduced. For instance, by using variable frequency fans, intelligent control systems, etc., the operating status of the equipment can be adjusted according to the actual load, avoiding unnecessary energy waste. At the same time, in terms of material selection, priority should also be given to environmentally friendly, non-toxic and easily recyclable materials to minimize the impact on the environment.

In actual design, customized design is also needed based on specific usage scenarios and requirements. For instance, in an electronics factory, as the products have strict requirements for molecular-level pollutants in the air, it is necessary to add special treatment equipment such as chemical filters to the system. In hospital operating rooms, it is necessary to ensure that the airflow in the surgical area flows in one direction to avoid the risk of cross-infection.

With the advancement of technology and the enhancement of environmental awareness, future purification HVAC design will pay more attention to the development trends of energy conservation, environmental protection and intelligence, creating a more comfortable, healthy and efficient production and living environment for human society.
