Ductwork Sizing Services in Cambridge
Accurate ductwork sizing is critical to the efficiency, performance, and noise control of any ventilation and air conditioning system. At Delta M&E, we provide specialised ductwork design services that ensure your system delivers the required airflow while meeting stringent acoustic and energy efficiency standards.
Why Expert Duct Sizing is Essential
Improperly sized ductwork can lead to several costly and problematic issues:
Excessive Noise: High air velocity through undersized ducts generates irritating noise and vibration, impacting occupant comfort.
Energy Waste: Undersized ducts create high system pressure loss, forcing fans to work harder and consume significantly more energy.
Poor Airflow: Oversized or poorly routed ducts can lead to insufficient airflow at terminals, resulting in inadequate heating, cooling, or ventilation in key areas.
Space Clashes: Inaccurate sizing leads to coordination issues with other services (pipes, containment, structure) in ceiling voids.
Our Ductwork Design and Sizing Process
We utilise advanced engineering principles and software to optimise every aspect of your ductwork system:
Airflow Requirements: Determining the exact required airflow rates for each room and zone based on building use, occupancy, and regulatory requirements (e.g., fresh air rates, cooling/heating loads).
Calculation Methodology: Applying industry-standard methods, such as the Constant Pressure Drop or Static Regain methods, to balance cost, space constraints, and pressure loss.
Acoustic Control: Selecting optimal velocities and incorporating acoustic lining and silencers to meet specified Noise Rating (NR) or Room Criteria (RC) levels for occupant comfort.
3D Coordination & Routing: Integrating the ductwork design within our BIM models to guarantee clash-free routing and ensure efficient installation within confined spaces.
Optimisation: Specifying appropriate duct materials, insulation, and fire/smoke dampers, ensuring compliance and long-term durability.
Delta M&E designs ductwork systems that are acoustically sound, energy-efficient, and perfectly coordinated with all other building services.
