RUIDONG's low-maintenance water-cooled screw-type commercial central air conditioning/chiller units + heat pump units deliver cooling capacities ranging from 70 kW to 280 kW. They are suitable for medium to large commercial and industrial buildings such as office buildings, hotels, shopping malls, factories, and medical facilities. The system employs shell-and-tube evaporators and condensers + high-efficiency screw compressors, compatible with eco-friendly refrigerants R410A / R407C. It seamlessly switches between cooling and heating modes to deliver year-round comfortable temperature control.
High-Efficiency Cooling & Heating: Water as the cooling medium offers superior thermal conductivity compared to air-cooled systems, enabling faster and more stable cooling/heating performance.
Multi-Functionality — Integrated Heating/Cooling + Hot Water Supply: Not only meets air conditioning needs but also provides hot water through a series-connected system, delivering a comprehensive comfort solution for buildings.
Low Energy Consumption, Eco-Friendly: Utilizes water-cooled systems and high-efficiency screw compressors for reduced energy usage. Employs environmentally friendly refrigerants like R410A/R407C, aligning with green building trends.
Quiet Operation: Noise levels maintained at approximately 72 dB(A), suitable for noise-sensitive environments such as office buildings, hospitals, and hotels.
Reliable, Durable, Long Lifespan: The water-cooled system is less susceptible to airborne contaminants. Combined with premium compressors (e.g., Danfoss/Copeland) and shell-and-tube heat exchangers, it delivers superior stability and longevity compared to conventional air conditioning systems.
High-Quality Compressors + Comprehensive System Protection: Screw compressors feature liquid hammer resistance, while built-in oil heating prevents damage from oil-refrigerant separation. The system incorporates multiple safeguards including high/low pressure protection, freeze protection, reverse/missing phase protection, overcurrent, overheat, low water level, and missing phase detection.
Intelligent, Flexible Control: Supports microprocessor-based controllers for temperature setting, real-time monitoring, automatic start/stop, and remote communication (RS-232/RS-485). Automatically adjusts operation based on load conditions to enhance energy efficiency and stability.
High Environmental Adaptability & Flexible Installation: Operates with diverse water sources—groundwater or cooling tower water—suiting commercial, industrial, and residential projects.
Commercial complexes/shopping malls/large retail spaces—centralized chilled/heated water supply
Office buildings—stable, quiet climate control and hot water provision
Hotels/Hospitals/Clubs — Venues demanding high comfort, stability, and quiet operation
Industrial Plants/Workshops/Processing Facilities — Production environments with stringent cooling or temperature control requirements
Medical, Research, Data Centers — Fields requiring precise environmental temperature/humidity control and stability
