Typical challenges in the laboratory environment.

The challenges most commonly faced in ventilation for laboratory environments involve the safety of the personnel, energy-efficiency, flexibility for changing the design ‘on the fly’, thermal comfort, suitable operation conditions, and reliability of the complete delivery.

Halton’s Vita Lab solutions control the fume cupboards’ and bio-safety cabinets’ airflow in line with demand and manage the supply airflow or pressure control for the laboratory room.

Laboratory hood ventilation response time
Importance of fast response time The time in which stable control velocity is reached after the hood opening has a significant effect on the exposure •Once the response time exceeds 3 seconds (equals 1s in X-axis) the exposure risk increases significantly •After 5 seconds from the sash movement, the maximum concentrations at the hood opening may reach the exhaust concentration

Laboratory design
Laboratory room airflow control with static pressure controller Halton VLZ. The Halton VLZ keeps static pressure in the main duct and it also measure the total exhaust airflow. The room controller Halton VLR communicates with Halton VLZ via RS-485 bus.

Halton Vita Room – Control Functions

Room controller  (VLR_M_RC) receives continuously updated actual total airflow rate of static pressure controller (VLZ)  via RS-485 field bus.

Room controller calculates the supply airflow rate setpoint so that the desired pressurisation or airflow balance is maintained  in the space; either negative, positive or neutral pressure.

Supply airflow rate is maintained at its setpoint by controlling the supply airflow damper (VLR_M_FG) using PID-principle and airflow measurement (VLR_M_FE) as feedback.
