3 Features / Benefits Efficiency Reliability High part-load efficiency (Max. COP: 1.60) With HVAC solutions operating at less than full capacity the majority of the time, efficiency in part-load is essential. LG s absorption chiller achieves energy savings and increased part-load efficiency via an advanced absorbent pump featuring state-of-the-art inverter control. The optimized system also decreases capacity in accordance with the volume of absorbent in circulation. Fuel consumption ratio (%) COP Fuel consumpion (Standard H series) High performance purge system with strong vacuum hold structure Each heat exchanger piping connection has been simplified and strengthened in order to maintain an optimal vacuum state, thereby minimizing potential leakage points. Self-diagnosis / Maintenance-notice alarm The microprocessor also has a self-diagnosis function, capable of alerting system managers to any potential issue; preventing inefficient operation and averting inconvenient breakdown. Operational conditions - outlet maintains temperature at a steady 7 degrees Celsius inlet capacity (%) inlet (ºC ) 100% 75% 50% 25% 32ºC 30.75ºC 29.5ºC 28.25ºC (%) Automatic anti-crystallization safety operation Intelligent system prevents the crystallization of absorbent through a safety-control logic algorithm. LG s LiBr- solution function enables uninterrupted system monitoring, resulting in the following benefits: Absorbent Concentration control Low temperator Generator Condenser temperature Input-energy control Less than 30 Min. Process during Power failure Power failure Automatic dilution operation Automatic restart Operation cost savings Up to 27% savings on operational costs annually (in comparison with a conventional 320RT chiller - based on South Korean gas tariff standards). Reduced CO2 emissions CO2 emissions can be reduced by up to 44 tons annually (in comparison with a conventional 320RT chiller). The LiBr- solution s concentration level is maintained at an optimum level, thereby preventing crystallization. The chiller uses sensors to detect the status of absorbent and controls temperature distribution by adjusting combustion levels.

4 Features / Benefits Convenience Convenient maintenance Operational management function State-of-the-art controller A high quality 7-inch display and a variety of communication ports make system operation and maintenance far more convenient. 7-inch color LCD screen with high resolution (800 x 480) Operation scheduling function Real time trend display Automatic anti-crystallization Advanced algorithm for highly effective temperature and safety control Running acquisition Graphic display of operational Certified EMC Communication supported: RS485 (standard) and Ethernet (optional) Communication protocol supported: Modbus (standard), BACnet Direct control of pumps and cooling tower Language: English / Chinese / Korean Auto-printing function (optional) Installation flexibility and ease of transport. The three-section design and smaller size of the product enhances convenience. LG s absorption chiller offers better performance than parallel-flow models as it absorbs a smaller amount of liquid. User-friendly positioning of valves and instruments results in more convenient operation and maintenance. Various interface solutions The onboard microprocessor boasts an impressive memory, enabling the chiller to store 20-years worth of operational settings, 301 error reports, and temperature from the last 10.6 days. This wealth of accumulated information is employed by LG s Absorption Chiller to guarantee efficient performance. Using industrial standard protocol converters, the chiller can be interfaced with the BMS (Building Management System). The reomote monitoring and control of the chillers is possible via BACnet/Eternet, BACnet/IP, Modbus, Modem or RS485. TCP/IP RS485 Multi-Drop 7 Color LCD with high resolution Real time operation status Time schedule Serial to LAN Converter RS485 Converter Procontrol Converter Connecting to max 8 units Evaporator & absorber Low temperature generator High temperature generator The chillers can be managed up to 255 units when using communication of RS485 or TCP/IP LG HVAC Solution 7
