LG expands heat pump research in various climate zones
LG Electronics announced significant progress in the development of next-generation heat pumps thanks to the work of its Global Heat Pump Consortium. The company is expanding research in various climate zones: from cold and humid regions to areas with extreme heat. The goal is to create energy-efficient heating solutions that work stably under any conditions.
What is known
In response to strengthening environmental requirements, particularly in Europe, where there is a gradual abandonment of gas boilers, LG has strengthened cooperation with scientific institutions worldwide. In 2023, the company created the CAHR Consortium for Advanced Heat Pump Research based at the Universities of Anchorage and Fairbanks in Alaska. Today, the consortium includes 12 universities from five countries.
At the AHR Expo 2025, LG presented joint research with American partners. They prove that the upgraded design of the external heat exchanger improves pump efficiency at low temperatures. These developments formed the basis for the new LG heat pump for cold climates, which received the AHR Innovation Award in the "Sustainability" category.
The European ECAHR Consortium, created in 2024, conducted field tests of the LG heat pump based on R32 refrigerant in Norway. The results showed a 60–80% reduction in energy consumption and carbon emissions compared to electric heaters.
Field studies are ongoing in the USA, China, Norway, Saudi Arabia, and other countries. They cover various types of devices, including Multi V and residential air conditioners. For example, detecting ice accumulation at the bottom of the outdoor unit in extreme frosts led to design changes that improve operational stability in cold weather.
LG also announced the creation of a testing center for tropical climates in Saudi Arabia in cooperation with universities from Korea and the Middle East. As LG ES President James Lee noted, the company continues to strive to create efficient and environmentally friendly solutions for consumers worldwide.
