Technical Field

[0001] This utility model relates to the field of building heating, specifically to a ground source heat pump energy-saving heat exchange device. Background Technology

[0002] Ground source heat pump heat exchange equipment is widely used in building heating, cooling and hot water supply. Its core is to achieve energy transfer and utilization by exchanging heat with underground or specific heat exchange medium. It is a commonly used heat exchange device in the field of energy conservation and environmental protection.

[0003] Existing heat exchange equipment suffers from limited contact between heat exchange components and water, and lacks structural designs to enhance heat transfer, resulting in low heat transfer efficiency and poor heat exchange performance. Furthermore, insufficient coordination among components in existing equipment leads to an unsmooth heat exchange cycle, causing significant energy loss and hindering energy-efficient operation. Additionally, the equipment's operation and subsequent maintenance are cumbersome, causing inconvenience in practical applications. Utility Model Content
