由清华大学和山东海阳富尔达有限公司共同开发的低温他热技术和节能冷暖机，日前通过有关部门挂定，并被认为达到国际先进水平。不须地下温泉，不须高温地热，将平常地下上镶贮藏的低温热源提取出来，经过转换后送入房间，冬天可以取暖，夏天可以制冷。在我国科学家的努力下， Developed by Tsinghua University and Shandong Haiyang Fulda Co., Ltd., the low-temperature heating technology and the energy-saving air-conditioner have recently been approved by relevant departments and are believed to have reached the international advanced level. Do not need underground hot springs, without high temperature geothermal, will be stored underground storage of low-temperature heat source extracted, after conversion into the room, the winter can be warm, the summer can be cooled. With the efforts of our country’s scientists,
