This air conditioning unit is specifically designed and developed for mobile communication base stations, taking into full consideration the special requirements of base stations under various complex conditions. The product quality is controlled according to strict industrial standards, and it is meticulously designed and manufactured for 10-15 years of 365 days × 24 hours of continuous operation. The air conditioner can operate normally in environments ranging from -30°C to 45°C, ensuring the safe, reliable, and stable operation of base station equipment. Applicable scope: mobile base stations, small computer rooms, microwave and ground stations, laboratories, testing rooms, telecommunications, cultural relics, precious archives, banks, and securities. Technical parameters: Refrigeration system: Single system; Cooling capacity: 7.3–19.8; Heating capacity (kW): 6, 9; Humidification capacity (kg/h): 4.59; Airflow (m3/h): 1850–4850; Air supply method: Top supply with front return (can be equipped with air cap) or bottom supply with top return; Dimensions (L × W × H) mm: 600 × 580 × 1700; 750 × 680 × 1870. Structural features: Efficient refrigeration system design: Utilizes highly efficient and reliable flexible scroll compressors, making system operation safer and more reliable. The product is designed for a long lifespan of 8,760 hours per year, with each unit undergoing strict factory inspections. Strong grid adaptability: Ultra-wide input voltage design, with phase loss and phase sequence protection functions, and automatic restart upon power restoration. Uses external rotor backward-curved blade centrifugal fans, which achieve up to 30% energy savings compared to standard fans. Smooth airflow through vibration-damping supports reduces noise levels, facilitates maintenance, and enhances lifespan and safety. Excellent human-machine interface: Full Chinese LCD backlit display with an easy-to-operate user-friendly interface, allowing users to easily access the unit's function menu and record the operating time of major components. Stored operating parameters and alarm records are retained even during power outages. Advanced intelligent control: Performs intelligent logical judgments based on set and displayed temperature and humidity parameters to determine the operating status. This technology reduces unnecessary energy consumption, improves the overall system's operational stability, and enhances temperature and humidity control precision. Network management function: Equipped with a standard RS485 interface, providing standard communication protocols and flexible master/standby switching functionality, enabling units to take turns on duty. Convenient remote program control provides reliable assurance for accurately judging equipment operating status. The advanced CO-WORK master-slave internal networking system allows multiple master-slave modules to be connected via a single cable to form a local network without requiring additional hardware. Easy transportation, installation, and maintenance: The unit is designed with full consideration for the simplest possible site transportation and installation. Compact dimensions allow the unit to pass through standard doors or elevators. Installation does not require heavy welding equipment, and the refrigerant pipelines and water connection pipes do not require on-site welding.
