長さ1/2の熱交換器とCO₂排出量半減可能な制御を搭載した「ライニング地中熱冷暖房システム」

In warm regions, the high setup costs hinder the widespread installation of geothermal energy systems. To overcome this obstacle, we have developed the Geothermal air conditioning system using LBHE. It delivers 50% energy savings compared to air-cooled heat pumps and reduces installation expenses by 30% compared to traditional geothermal systems, even in warm climates. This paper examines its two main components: the Lining Borehole ground Heat Exchanger and the unified heat balance control.
