Modular Air Handling Units for Cleanrooms

In cleanroom projects, modular air handling units (AHUs) are essential. They maintain high indoor air quality in critical spaces. Built with different air treatment sections, modular AHUs provide precise control. Moreover, they can be customized to meet specific cleanroom needs. This article explores key selection parameters and application points. With the right AHU, you’ll achieve efficient and energy-saving air management.

Key Selection Parameters for Modular AHUs

To choose the right modular AHU, you must consider various parameters. These include total supply air volume and fresh air ratio. Additionally, cooling and humidification capacity are essential factors. Each parameter plays a role in air quality and system efficiency.

  • Total Supply Air Volume: First, this core parameter ensures even air distribution. It must cover all areas evenly. To calculate total supply air volume, consider the room size. Cleanliness levels are also critical for accuracy.
  • Fresh Air Ratio: Furthermore, a higher fresh air ratio increases the system load. Cooling, heating, and humidity loads all rise as fresh air ratio increases. Therefore, determining the correct fresh air ratio prevents load calculation errors. This step is essential to avoid performance issues.

In summary, choosing the correct parameters impacts air quality directly. It also determines the system’s energy use and operational efficiency. Accurate modular AHU parameter selection is a key step in controlled cleanroom environments.

Precise Control of Air Changes for Cleanliness

In cleanrooms, air changes per hour (ACH) is critical for air cleanliness. According to GMP standards, recommended ACH vary by cleanliness level.

  • Class B (ISO 5): 45–60 air changes per hour
  • Class C (ISO 6–7): 25–30 air changes per hour
  • Class D (ISO 8–9): 15–20 air changes per hour

These standards help ensure cleanroom air quality. Consequently, modular AHUs can perform at peak levels in various controlled environments.

Case Study: Modular AHUs in Real Cleanroom Settings

For example, in a cell lab project, the cleanroom’s needs were carefully considered. Its cleanliness level and room size determined the required air volume. Ultimately, the design resulted in a supply air volume of 9,180 m³/h, with a fresh air ratio of 17%. Through this thoughtful design, the system met cleanliness needs and saved energy. This case shows that scientific planning can significantly improve AHU system performance.

Energy Savings and Environmental Benefits

With growing environmental demands, energy-saving and eco-friendly features are crucial. Modular AHUs excel in energy efficiency. By optimizing fresh air ratios and supply air, energy use is reduced. Moreover, using high-efficiency filters cuts operational costs. Additionally, smart control systems help lower carbon emissions, aligning with modern sustainability goals.

Summary

In conclusion, selecting the right modular air handling unit is essential for air quality. It also ensures comfort in cleanroom environments. Proper supply air calculations are critical, and fresh air ratios and energy-efficient design are equally important. Each detail has a direct impact on the AHU’s performance.

Choose modular air handling units to revitalize your cleanroom. This decision creates a cleaner and healthier workspace for your business. Through scientific selection and precise design, modular AHUs offer an efficient and energy-saving solution. As a result, environmental control becomes easier and more reliable.

Frequently Asked Questions (FAQ)

  • How do I calculate the supply air volume for modular AHUs?
    First, multiply the required airflow by 1.1–1.2 to offset leakage and pressure loss.
  • How should I determine the appropriate fresh air ratio?
    Consider exhaust needs first. Typically, fresh air ratios of 10%–30% are sufficient for most cleanroom needs.
  • What are effective ways to optimize energy savings in AHU systems?
    To begin with, optimizing supply air volume and fresh air ratio is effective. Using high-efficiency filters and heat recovery technology also saves energy.
