Thermodynamic analysis of a hybrid absorption two-stage compression refrigeration system employing a flash tank with indirect subcooler

Armin Emamifar

Volume 12, Issue 2 , February 2023, , Pages 145-159


  In this research, the thermodynamic analysis of a two-stage absorption compression refrigeration system employing a flash tank with indirect subcooler is presented. The absorption cycle uses LiBr-water solution as the working fluid and prepares the high temperature medium for the bottoming cycle, which ...  Read More

Operational trends of a mini parabolic solar collector for agricultural purposes in a non-active solar environment

Moses EMETERE; Samuel Sanni; O Dauda; A Akinsiku; O Osunlola; A Adejumo

Volume 10, Issue 1 , September 2020, , Pages 201-210


  The mode of operation of mini parabolic solar panels made of germanium, mild steel and aluminium were investigated experimentally, as means of providing heated water on a farmland; the process was also modelled. Angular adjustments of the solar collectors from 70-90o were adopted in order to determine, ...  Read More

Design and construction of fruit solar drier for rural settlements

Moses EMETERE; Isaac Odun-ayo

Volume 9, Issue 2 , February 2020, , Pages 323-330


  This research focuses on the need for preserving fruits in rural areas to prevent waste. The solar drier is made of vital chambers i.e. the concentrator chamber (that harvests the solar irradiance), the transport pipe (that transports the heat generated by convection) and hanger chamber (where the fruits ...  Read More
