South Korea's Samsung Electronics and the US Department of Energy's Oak Ridge National Laboratory have begun testing a cold-climate vapor-compression heat pump technology that Samsung says can maintain stable heating performance at temperatures below minus 30 C. The Cold Climate Vapor Compression Space Heating and Multi-functional Equipment research project will assess vapor-compression technology that uses refrigerant phase changes to absorb and release heat. In the system, the refrigerant absorbs heat from the outdoor environment before being compressed into a high-temperature, high-pressure ...Den vollständigen Artikel lesen ...
