Holtop has been selected as the key HVAC system provider for the Weinan Sixth Hospital (Municipal Infectious Disease Hospital), a critical public health infrastructure project in Shaanxi Province, China. This contract, representing Holtop's 53rd major project in 2025, involves the supply and integration of 1,070 sets of specialized ventilation equipment. The project aims to establish a modern, safe, and energy-efficient environment for infectious disease treatment, significantly enhancing the region's public health response capabilities.
The core challenge was to design a ventilation system for a dedicated infectious disease facility that prioritizes utmost safety. The system must:
· Create and maintain strict, reliable pressure gradients between contaminated, semi-contaminated, and clean zones to prevent airborne pathogen cross-transmission.
· Ensure a scientific, unidirectional airflow path that actively removes contaminated air from sensitive areas.
· Guarantee continuous, fail-safe operation with high energy efficiency to manage long-term operational costs.
· Provide intelligent, centralized monitoring and control for rapid adaptation to different operational modes (e.g., regular vs. outbreak scenarios).
Holtop engineered a comprehensive Digitally-Controlled Smart Fresh Air System, forming the hospital's "respiratory lung" for safety and efficiency. The core solution comprises three integrated components:
· Digitally-Controlled Smart Fresh Air Handling Systems: Serve as the central air quality management hub.
· Power-Distributed Adaptive Ventilation Modules: Enable precise, zone-specific airflow and pressure control.
· High-Static-Pressure Intelligent Airflow Regulation Units: Ensure stable pressure differentials are maintained under all conditions.
· Automated Infection-Control Airflow: The system's intelligent control modules automatically regulate fan speed and damper positions to maintain precise pressure gradients. This creates a defined, controlled airflow path from clean to less clean areas, significantly minimizing the risk of cross-infection for healthcare workers and patients.
· High-Efficiency, Non-Contact Energy Recovery: A core thermodynamic heat recovery unit facilitates energy exchange between exhaust and fresh air streams without any physical contact or mixing. This technology captures up to 70-80% of thermal energy, drastically reducing the load on heating and cooling systems and leading to substantial energy savings.
· Resilient & Intelligent Operation: Built with robust components for 24/7 reliability, the system features full digital integration with the Building Management System (BMS). It offers real-time monitoring, fault diagnostics, and remote management capabilities, ensuring optimal performance and simplified maintenance.
The Weinan Sixth Hospital project exemplifies Holtop's expertise in delivering mission-critical HVAC solutions for the healthcare sector. By combining advanced pressure control, intelligent automation, and efficient heat recovery, Holtop provides a turnkey system that ensures a safer environment for medical staff and patients while promoting sustainable operation. This case serves as a strong reference for international clients developing hospitals, isolation units, laboratories, or any facility requiring the highest standards of indoor air safety and energy performance.
