Cleanroom HVAC Essential Considerations Before Purchase
Standard HVAC systems manage humidity, temperature, and air pressure, while also offering filtration and control over airflow speed and direction within a space. Cleanroom HVAC systems, however, operate with higher air exchange rates and employ high-efficiency particulate (HEPA) filters to maintain a sterile environment. This stringent air filtration is crucial for industries such as medical, pharmaceuticals, and research and development laboratories. Choosing the right cleanroom HVAC system depends on several factors influencing system size and design.
Understanding Total Heat Load
Calculating the total heat load of the room is essential as it determines how much heat the cleanroom HVAC system needs to remove. This includes all devices drawing power within the space. To ensure adequate system sizing, factors such as square footage, number of occupants, types of lighting, and presence of windows affecting light and heat ingress should be considered.
Air Source: Internal vs. External
Knowing where the HVAC system draws air from is critical for effective cleanroom cooling. The source can be external or internal to the facility, and its condition must meet acceptable standards before pressurization. Understanding the air change rate—how frequently external filtered air replaces current cleanroom air—is vital. Systems may either recirculate filtered air or operate as single-pass systems that exhaust air outside the cleanroom.
Exhaust Considerations
Consideration of exhaust is often overlooked but crucial. Understanding the amount of air exhausted from the cleanroom and any leaks is vital for selecting an appropriately sized HVAC system. Exhausted air needs to be replaced with conditioned air, which consumes more energy compared to recirculated air within the cleanroom.
Temperature, Humidity, and Dew Point Ranges
Knowing the cleanroom's temperature, relative humidity, and dew point ranges throughout the year is crucial for HVAC system design. These parameters can vary significantly across seasons and impact system performance. Identifying maximum humidity levels at both high and low temperatures each season helps in selecting the right HVAC system type and size.
