150 bed hospital HVAC design and engineering – Raipur
Specialized HVAC execution for healthcare facilities ensuring safety, hygiene, and precision control.
Introduction
Designing HVAC systems for healthcare facilities requires a highly specialized approach that goes far beyond conventional air-conditioning. A 150-bed hospital in Raipur represents a critical infrastructure project where indoor air quality, infection control, thermal comfort, and energy efficiency must all work seamlessly together. HVAC design in such facilities directly impacts patient recovery, staff productivity, and overall operational safety.
This 150-bed hospital project in Raipur focuses on delivering a robust, energy-efficient, and compliant HVAC system tailored to healthcare standards. The design integrates advanced air-conditioning technologies, precise airflow management, and smart control systems to ensure a safe and hygienic environment across all departments including ICUs, operation theatres, wards, and diagnostics.
Key Features of the Hospital
1. Zoning & Space Classification
Different hospital areas have different HVAC requirements. Critical zones like operation theatres, ICUs, and isolation rooms require stringent air quality and pressure control, while general wards and OPDs follow comfort-based conditioning.
2. Infection Control & Air Quality
Maintaining high indoor air quality is essential. HEPA filtration, controlled air changes per hour (ACH), and proper ventilation strategies are implemented to minimize airborne contamination and hospital-acquired infections.
3. Pressure Differentials
Positive and negative pressure rooms are designed to control airflow direction. Operation theatres are maintained at positive pressure to prevent contamination, while isolation rooms use negative pressure to contain infections.
4. Air Changes Per Hour (ACH)
Each space is designed with specific ACH requirements as per healthcare standards. Higher ACH is maintained in critical areas to ensure continuous dilution of contaminants.
5. Temperature & Humidity Control
Precise control of temperature and relative humidity is essential, especially in operation theatres and ICUs, to ensure patient safety and equipment performance.
