A Fundamental Study of Refrigerant-Line Transients: Part 2--Pressure Excursion Estimates and Initiation Mechanisms

Dangerous pressure excursion incidents have been associated with condensation-induced shock and vapor-propelled liquid slugging; however, some of the mechanisms responsible for initiating these hydraulic transients in industrial refrigerating systems are unclear. In a companion paper (part 1), an ex...

Summary:Dangerous pressure excursion incidents have been associated with condensation-induced shock and vapor-propelled liquid slugging; however, some of the mechanisms responsible for initiating these hydraulic transients in industrial refrigerating systems are unclear. In a companion paper (part 1), an exhaustive compendium of the relevant literature was presented. In this paper, specific shock initiation mechanisms are described, an analysis for estimating the pressure excursion of a shock is presented, and a method for avoiding one possible path to hydraulic shock in refrigerating systems is presented.
