Solar Air Conditioning Heat Pump with Minimized Dead Volume

摘要: A method and apparatus that reduces the dead volume in a heat engine or pump, such as duplex Stirling Vuilleumier cycle device, by nesting components of displacer regenerator nearly all working fluid is purged from interstices elements other spaces are not involved doing useful work at each portion cycle. Particularly, more scalable efficient for providing solar air conditioning refrigeration means heated cylinder alternately pressurizes depressurizes separate cooling directly transferring thermally induced pressure changes to optimized times cycle, under control numerically controlled actuation system can much lower rate than mechanically coupled harmonically phased systems.
