广义上的传热流体，以及水和蒸汽，包括：制冷剂、有机流体、熔盐、液态金属和热气体。早在1973 年夏季，首批有机热载体传热设备已在工业领域成功应用。此后，该技术持续稳步发展，新的法规和规范相继出台，应用领域也不断拓展。尤其值得一提的是，能够在几乎无加压的条件下传递并精细控制高达400°C 的温度，正是采用有机流体的传热技术的一大优势。根据水的饱和蒸汽压数据，在370°C 时，饱和蒸汽的绝对压力约为 21.04 MPa（约 210.4 bar）

Heat transfer fluids in a broader sense, as well as water and steam, include refrigerants, organic fluids, molten salts, liquid metals, and hot gases. As early as the summer of 1973, the first heat transfer equipment using organic heat transfer fluids had been successfully applied in industry. Since then, the technology has continued to develop steadily, with new regulations and standards being introduced, and application fields expanding continuously. In particular, the ability to transfer and finely control temperatures up to 400°C with virtually no pressurization is precisely one of the major advantages of heat transfer technology using organic fluids. According to the saturation vapor pressure data of water, at 370°C, the absolute pressure of saturated steam is approximately 21.04 MPa (about 210.4 bar).
