A combined refrigeration and power cycle, which uses ammonia-water as the working fluid, is proposed by combining Rankine and vapour absorption cycles with an advantage of varying refrigeration capacity to power output ratio. The study investigates the usage of low temperature heat sources for the cycle operation. Results of parametric analysis are presented, which show the scope for optimizati...

Aberrant false-positive reactions in negative-controls during ELISA testing for Clostridium difficile indicated the potential for false-diagnoses. Experiments with 96-well products showed a maximum peak of false-positive immunoassay reactions with the provided negative-control reagents after 5 refrigeration-to-room temperature cycles (P < 0.001), decreasing thereafter with additional refrigerat...

VapCyc is a vapor compression refrigeration simulation tool which features charge management and component inter-changeability. In addition to the four basic cycle components, additional components, such as pipes, bypass valves and various auxiliary heat exchangers can be added to the system at run-time, rather than design time, making the simulation very user-friendly. The simulation is achiev...
