Chiller System HVAC

From cooling source equipment to terminal distribution, the system encompasses chillers, cooling towers, pumps, plate heat exchangers, pressurization and make-up units, water treatment systems, piping and valves, and intelligent group control - all uniformly designed and selected to ensure compatibility across all system components, avoiding efficiency losses and operational risks caused by mismatched equipment. All core equipment is factory-prefabricated and pre-commissioned, requiring only positioning, piping, and utility connections on-site for immediate operation.

The chiller is the core equipment of the cooling source system, and the compressor type directly affects system efficiency, stability, and application range. The system offers the following compressor types for project selection:

• Scroll Compressor: Compact structure, smooth operation, low noise - suitable for small to medium cooling capacity requirements (typically 10~200RT per unit), ideal for general industrial plants and comfort air conditioning applications
• Screw Compressor: Smooth operation, excellent part-load efficiency, low failure rate - suitable for medium cooling capacity requirements (typically 50~500RT per unit), the most widely used compressor type in industrial applications
• Centrifugal Compressor: Large single-unit capacity, high full-load efficiency, compact footprint - suitable for large cooling capacity requirements (typically 200~3000RT per unit), ideal for centralized cooling in large industrial parks
• Magnetic Bearing Centrifugal Compressor: Utilizes magnetic bearing technology, oil-free operation, zero friction loss, exceptional part-load efficiency - suitable for large projects with stringent efficiency requirements (typically 100~1500RT per unit), with COP可达6.0~7.0+, delivering significant total lifecycle cost advantages

Supports air-cooled, water-cooled, or dual-cool source configurations, flexibly selectable based on project-specific water resource availability, climate conditions, and reliability requirements:

• Air-Cooled: Utilizes air-cooled chillers, simple system with no cooling towers or water treatment systems required - suitable for water-scarce regions or industrial sites where cooling tower installation is not feasible
• Water-Cooled: Utilizes water-cooled chillers + cooling towers, delivering optimal overall efficiency (COP 5.0~6.0+) - suitable for industrial projects with abundant water resources pursuing ultimate energy efficiency
• Dual Cool Source: Combines air-cooled and water-cooled systems with two independent cooling sources providing mutual backup - ensures year-round uninterrupted cooling for mission-critical industrial facilities

Full-chain energy optimization from cooling source to distribution, featuring high-efficiency compressors and heat exchangers, equipped with electronic expansion valves and EC fans for system-level on-demand cooling. Optional free cooling modules maximize utilization of outdoor natural cooling sources during transition seasons and winter, significantly reducing compressor energy consumption. Overall system efficiency outperforms single-equipment optimization, substantially reducing annual electricity costs for industrial plant cooling systems.
