Supersonic Ejector (SE) is a thermally-driven fluidic compressor that replaces the electro-mechanical compressor in Reverse-Rankine refrigeration/heat pump cycles. These widely used thermal cycles account for billions of kWh of electric energy and produce hundreds of millions of metric tons of...

Air-conditioning and heat pumping performance of R32/R152a mixture is measured in the composition range of 20–50% R32 with an interval of 10% for the comparison with HCFC22 in a water source heat pump bench tester. Tests are carried out under the same capacity in the bench tester equipped with...

This paper studies the long-term distribution of energy-efficiency outcomes in the German residential sector. To uncover the underlying energy efficiency of buildings, we estimate the causal response of building-level heat energy demand to variability in heating degree days. We examine...

Sanitation is required for biogas plants handling slaughterhouse and food waste according to EU legislation. The standard method is pasteurization at 70 °C for 60 min, but integrated thermophilic sanitation (ITS), requiring 52 °C for 10 h in the digester, has been approved by the Swedish...

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...
