nanoparticles

by Inderscience Publishers  (May 28, 2013)

The refrigerator exergy efficiency (EE) with nanoparticles in the working fluid was investigated experimentally. Mineral oil (MO) with TiO2 nanoparticles mixtures were used as the lubricant instead of Polyol ester (POE) oil in the R134a, R436A (R290/R600a–56/44–weight %) and R436B (R290/R600a–52/48–weight %) refrigerator. The results indicate that ...

Fast start-up of expanded granular sludge bed (EGSB) reactor using stored Anammox sludge

by IWA Publishing  (Apr. 10, 2014)

Stored Anammox sludge (SAS) was used in an expanded granular sludge bed (EGSB) reactor treating synthetic wastewater with the aim of evaluating its possible use as seed sludge. The SAS had been kept in a refrigerator (4 °C) without any feed. After 2 years, only 1–2% Anammox bacteria could survive in the SAS. However, it soon ...

Thermo-ecological performance optimisation of two stage irreversible refrigerators

by Inderscience Publishers  (Mar. 23, 2009)

The present study investigates the optimal performance of two stage refrigeration system based on thermo-ecological performance criterion. To maximise the ecological performance function, the working fluid temperatures are optimised. The optimal conditions such as cooling load, entropy generation rate and Coefficient of Performance (COP) are ...

Optimisation of an irreversible Carnot refrigerator working between two heat reservoirs

by Inderscience Publishers  (Dec. 2, 2009)

A model of finite-resources optimisation for irreversible refrigerators is presented in this paper. An irreversible Carnot refrigerator operating between two heat reservoirs is analysed. Several important optimum results, subject to different resource constraints have been obtained. The relations among these results are also discussed. The results ...
