| Dear trnsys-user, Am trying to simulate an adsorption refrigerator system using CPC collector. My collector receiver/adsorber is made of two pipe arranged concentrically(with common centre) with zeolite 4A packed in between the concentric pipe (the innermost is perforated) and it receives direct solar radiation.This type of CPC collector is not in the trnsys library. Pls advice me on how to simulate such design. Thanks Omisanya Nua ABU Zaria |
