With increased instances of unusual weather, people are more engaged to use renewable energies. In that, we, Ikeda Technical Co., Ltd. has created a new geothermal energy AC system called “Geo-MAX”. Our system offers a very large air volume and efficient heat exchange ability by circulating water around φ800mm pipes buried at 2 meter deep. Because Geo-MAX gives one of the largest air volumes among other geothermal-source ACs, it is best used in large-size architectures where no other geothermal systems could not have been used, such as factories, gymnasiums, public facilities, housing complex, greenhouses and livestock shelters. For example, in summer, Geo-MAX helps prevent heat strokes at gymnasiums and factories and gives better air condition to public evacuation shelters. Furthermore, Geo-MAX is a cost-effective system and basically only requires “space” for installation. Thus, we believe Geo-MAX will lead a “Clean Energy Revolution” and change the way we use geothermal energy not only in Japan but in the entire world. We aim to further develop the system and combine it with other natural energies, and offer solutions for the energy problems.
