On September 21, 2024, the 14th National Geothermal Conference was successfully concluded in Jinan, Shandong Province. The theme of this conference is "Exploring and Innovating, Joining Hands to Enter the New Era of Geothermal Energy", closely focusing on the national "dual carbon" strategic goals, aiming to build an integrated comprehensive platform of "government, industry, academia, research, finance and utilization", and promote the development of geothermal energy industry towards scale, efficiency and high quality.

Yantai Land Air Conditioning Industry Co., Ltd., as an important enterprise in the heat pump industry, actively participated in this grand event. At the conference venue, Land set up a professional booth to introduce in detail some of Land's application demonstration projects in the field of mid to deep geothermal+heat pump cascade extraction to industry leaders, experts, and peers in attendance. These projects mainly utilize efficient, energy-saving, and environmentally friendly high-temperature heat pump technology, using geothermal wells as the heat source, and through the "plate exchange+Land high-temperature centrifugal heat pump" mode, utilizing geothermal well water in a cascade manner until the lowest temperature is refilled. At the same time, the system water is heated to high temperature by plate exchange and centrifugal heat pump in series, effectively meeting the heating needs of multiple projects.
