This paper focuses on the climate change challenge faced by Central & Eastern European countries both those inside the European Union and those outside it. They have enormous energy intensity and associated greenhouse gas (GHG) emissions, mainly from energy production, which is oil, and worse,...

Present work is focused on building a TRNSYS simulation model of solar water heating (SWH) system using heat pipe evacuated tubes, hybridized with conventional fuel (i.e., natural gas) backup to provide uninterrupted thermal energy supply. An experimental facility was developed to validate the...

As mirrors used in concentrating solar systems influence the thermal efficiency of the systems collectors to a large extent, the reflectance of mirrors plays a critical role in the thermal efficiency of parabolic trough solar collectors. The studies already done by scientists in terms of how to...

A prototype north wall insulated greenhouse dryer has been fabricated and tested in no-load conditions under natural convection mode. Experimentation has been conducted in two different cases. Case-I is when solar collector placed inside the dryer and Case-II is North wall insulated greenhouse...
