Foreign Media: Chinese Scientists Achieve Breakthrough in Ultra-High Temperature Heat Pump Technology, Possibly Using Sunlight to Melt Ores.
Over the past century, the upper limit for converting low-grade heat energy into high-temperature industrial energy was 200 degrees Celsius. Now, a Chinese research team has developed a revolutionary heat pump without moving parts, which is driven by a 145-degree Celsius heat source and outputs a temperature of 270 degrees Celsius.
This technology can use solar collectors or industrial waste gas to generate high-temperature heat energy, which can be used in fields such as ceramics, petrochemicals, and metallurgy. For example, it can enable solar farms to directly produce high temperatures required for smelting iron ore or refining aluminum, or chemical plants can recover their own waste heat for molecular cracking or synthesis. Nearly half of the world's final energy consumption is used for heating and cooling, with industry accounting for nearly half of that. This breakthrough is of great significance.
