LG Electronics is showcasing the full scale of its HVAC (Heating, Ventilation, and Air Conditioning) technology at LG Science Park, a vast research and development complex covering approximately 1.83 million square feet, roughly the size of 25 soccer fields.
At the heart of the facility’s climate control system is a fully integrated HVAC solution developed by LG Electronics and its wholly owned subsidiary, ACE Cooling & Air Conditioning. From chillers and air handling units to building-wide automation, the system highlights LG’s ability to deliver high-efficiency, low-carbon, and AI-powered environmental control for large-scale facilities.
Located on Basement Level 3 of Building W5, the main mechanical room houses a total of eight chillers across three types: turbo, absorption, and screw. Each type is strategically used to maximize operational stability and energy efficiency.
The turbo chillers, equipped with high-performance dual-stage compressors, are designed for large commercial and industrial spaces. Each unit delivers cooling performance equivalent to approximately 400 stand-type air conditioners for 640-square-foot areas. These chillers use environmentally friendly R-134a refrigerant and boast an industry-leading COP (Coefficient of Performance) of 6.25. They are also certified by the Air-Conditioning, Heating & Refrigeration Institute (AHRI) and Electrical Testing Laboratories (ETL) in the United States.
On the opposite side of the room are three large absorption chillers, each measuring approximately 22.3 feet in length, 14.8 feet in width, and 13.1 feet in height—comparable in size to an orca whale. These chillers use waste heat or medium-temperature hot water, often sourced from district heating systems. They are highly energy-efficient, consuming less electricity and achieving a COP of 0.7, and are recognized as certified high-efficiency equipment.
Also installed are screw chillers, which utilize twin rotary compressors to cool water. Compared to competing models, LG’s screw chillers reduce unit weight by up to 29% and footprint by up to 36%, offering exceptional space efficiency. They also support nighttime ice storage using off-peak electricity, helping reduce daytime power usage and operating costs.
The chilled water is circulated throughout the facility via Air Handling Units (AHUs), which regulate air temperature, humidity, circulation, and filtration. This cooled air is then precisely adjusted by Air Terminal Units (ATUs), which tailor airflow and temperature to the specific needs of different areas, such as meeting rooms, laboratories, and shared spaces—minimizing energy waste through automated controls.
All AHUs and ATUs were developed by ACE Cooling & Air Conditioning, which specializes in the design and production of air system equipment. These systems are fully integrated with LG’s central Building Management System (BMS).
The entire HVAC network is managed through LG BECON Cloud, an AI-powered smart building platform. It provides real-time monitoring, automated energy optimization, and predictive maintenance capabilities that improve system reliability and reduce energy consumption.
An LG Electronics spokesperson commented, “LG Science Park serves as a live demonstration of our HVAC technology and intelligent building solutions. Our integrated systems deliver outstanding efficiency, sustainability, and user comfort, setting a new benchmark for smart building climate control.”
