One billion air-conditioners are in operation worldwide. There will be three billion in 2050. This workshop summarizes and discusses new approaches of comfort cooling with focus on breakthrough improvements for vapor compression technology, exemplifying a path to reducing the size of the residential outdoor unit by a factor of two and its weight by a factor of three while increasing energy efficiency. During keynote lectures on Wednesday afternoon, we lay out the overall concepts, followed by detailed material on Thursday. Presentations focus on novel compressor technologies, heat exchanger designs and system integration approaches that all point towards how radically smaller, better, lighter, and more efficient vapor compression air-conditioning technology is within reach.  The workshop concludes Friday lunchtime after a brainstorming session to define remaining research needs and panel discussion.
