Abstract: The growing demand for air conditioning, particularly in hot and humid climates has caused a significant increase in demand for energy resources. A promising solar technology with potential to ...

Abstract: A parametric study is performed for a relatively large size helium cryocooler which utilizes a ringless piston. The results are presented in a dimensionless form and may be useful for other ...

Abstract: This paper describes the results of a search for an optimum profile that will maximize the dynamic stability of gas lubricated ringless pistons. Previous work indicated that the common cylindrical ...

Abstract: A mathematical model is developed for analyzing the dynamics of gas lubricated ringless pistons. It takes into account the effects of piston-cylinder geometry, dynamic properties of piston and ...

Abstract: In earlier work, a novel open absorption cycle was proposed, capable of producing both cooling and dehumidification for air conditioning, utilizing low-grade heat. The system, referred to as DER ...
