An innovative solution to reduce HVAC energy consumption in classified areas A new HVAC control system intensifies efficiency in aseptic drug cleanrooms. Pharmaceutical companies face the challenge of reducing production costs without negatively affecting the quality of final products. HVAC systems are one of the main energy consumers in pharmaceutical facilities, especially in sterile production. Therefore, energy saving is especially significant in this field.

The Smart Cleanroom is an innovative flexible solution for cleanrooms that adjusts the supply air flow using a linear particle counter connected to the HVAC control system, reducing energy consumption and operating costs and providing excellent efficiency for the company. provides pharmaceuticals.

In the pharmaceutical industry, clean rooms are in high demand due to the role they play in creating a contamination-free environment for product research and development. Given that pharmaceutical processes are constantly evolving, the need for clean rooms that can meet the needs of It is very important that the variable matches. Our awareness of this at Total Clean Air has placed us in a unique position to offer cleanrooms that offer flexibility, optimal performance and security.

Smart Cleanroom henceforth (SmartCR) is a flexible solution for cleanroom control based on the idea of ​​reducing the power consumption of the HVAC system, reducing air changes in cleanrooms with disturbed ventilation, always working within the limits that guarantee the air quality classification. and follows the following.

Regulations contained in EU GMP and ISO 14644-1 standard. SmartCR uses data collected by particulate counters installed for indoor monitoring systems to act on the only parameter in cleanroom design that remains constant: the air flow rate in conventional ACH HVAC systems at the design stage. And then it is fixed. Particle counters are usually not permanently installed, therefore warranting renovations that increase room classification and are not controlled.

SmartCR is a special HVAC control system that adjusts the air flow rate to provide the optimal air flow required to ensure the room temperature, relative humidity, room differential pressure/air flow direction and particle number under control, meaning that Significant savings in HVAC consumption.
SmartCR was developed specifically for the high quality pharmaceutical industry. It is conceived with a conservative function to ensure the stability of the critical parameters of the controlled environment at all times.

 

Benefits of ACH optimization include:

Reduced capital costs: Less airflow results in smaller fans, which reduces both initial investment and manufacturing costs. A 20% reduction in ACH results in a nearly 50% reduction in fan size. However, the optimization of ACH requires a more sophisticated and efficient control system with the integration of an air particle counter monitoring system.
Reduced energy consumption: The energy saving opportunities are comparable to the potential reduction in fan size. According to the laws of fan inclination, the power of the fan is proportional to the cube of the rate of air change or air flow. A 30% reduction in air change rate results in a power reduction of approximately 66%.
Smart CleanRoom

How does Smart Cleanroom work?

SmartCR is an engineering solution for cleanroom environmental control, consisting of an automated HVAC system with the following elements: AHU equipped with an EC fan (for energy saving and better fan speed control);
  • Fan flow control
  • Room temperature and humidity control (temperature and relative humidity transmitters that control the cooling and heating valves in the AHU coils)
  • Air particle counter (hereinafter APC) for continuous counting and monitoring of airborne particles
  • Motorized dampers (variable air volume type) in the supply air network to keep the air flow constant in the rooms.
  • Motorized dampers in the return air grille to control room differential pressure.
Pressure transmitters to control the differential pressure of the room, the degree of cleanliness of the environment can be configured in the system:

SmartCR solution offers 2 operating modes:
Normal mode: constant supply air flow with ACH adjustment as per design.
ECO Mode: Variable supply current that is set by APC capture

SmartCR comes with a setup option to select the type of particle tuning by the control loop: at rest or in operation. During system start-up, the minimum air flow is set to achieve the correct classification of room cleanliness in "at rest" conditions. It is verified that environmental conditions are maintained within the specified limits for at least 12 hours.

The system is then challenged to restore room conditions outside of specification, establishing temperature and relative humidity. Finally, the stability of the differential pressures is tested at the previously set minimum airflow. When opening the doors, the pressure difference changes, it is possible to change the direction of the air flow and contamination can enter the clean room. Therefore, it is necessary to achieve a stable pressure under any conditions and maintain it. Any change in room or reference pressure causes the control system to respond and change the airflow to or from the controlled space. is an innovative flexible solution for cleanrooms that adjusts the supply air flow using a linear particle counter connected to the HVAC control system, reducing energy consumption and operating costs and providing excellent efficiency for the company. provides pharmaceuticals.
