Chilled Water & HVAC Unit Noise Abatement for Taiyuan Central Hospital

Project Overview

● Project Name: Central HVAC Unit Noise Abatement & Acoustic Control

● Location: Taiyuan, Shanxi Province, China

● Industry: Healthcare & Medical Architecture

● Products Applied: Acoustic Enclosure Barriers, Hybrid Impedance Silencers, Pipe Lagging

Project Background & Engineering Challenges

Central HVAC units at Taiyuan Central Hospital produced cumulative mechanical vibration and high-velocity airflow noise that drifted into adjacent ward quarters.

The primary engineering challenges were managing massive air volume requirements without impairing heat dissipation efficiency and carrying out heavy structural installation safely in a densely populated medical facility.

Engineering Noise Control Solution

● Acoustic Enclosure Barrier: Erected perimeter acoustic walls with sound-absorbing inner linings around the primary HVAC machinery.

● Hybrid Impedance Silencers: Fitted custom-engineered hybrid silencers on intake and discharge air vents to suppress wide-frequency airflow noise.

● Vibration Isolation & Piping Insulation: Installed heavy-duty elastomeric vibration isolation pads under equipment skids and wrapped high-pressure fluid lines with multi-layer acoustic lagging.

Key Results

● Ambient noise in inpatient wards dropped well below medical building acoustic exposure limits.

● Thermal heat exchange and system efficiency remained fully operational without overloading compressor lines.
