The energy transition, originating in the limitation of fossil resources and greenhouse gas
(GHG) emission reduction, is the basis of many studies on renewable energies in different …

Diffusion-absorption refrigeration (DAR) is a cooling technology that uses a three-
component working fluid and a thermally-activated bubble-pump for fluid circulation. DAR …

The fact that diffusion absorption refrigeration (DAR) systems can also work with low power
plants has increased the interest in these cooling systems again. The DAR systems are …

Poor startability under cold-start conditions is a long-term obstacle of the compression
ignition engine and adjustment of the injection pressure is an effective way to improve the …

A novel air-cooling bubble absorption/compression hybrid refrigeration experimental set-up
of 3 kW was designed and assembled, using R124-DMAC as working fluids. The described …

Nowadays, refrigeration performance enhancement with the minimisation of emission gases
is challenging. Several Researchers are used eco-friendly working fluids and waste heat …

Diffusion absorption refrigeration (DAR) is a small-scale cooling technology that can be
driven purely by thermal energy without the need for electrical or mechanical inputs. In this …

A single-effect absorption refrigeration system that uses LiBr-water solution and engine
exhaust gas is investigated. The generator is a spiral fin-and-tube heat exchanger, while the …

In this study, a hybrid absorption chiller was proposed as a part of the energy supply facility
for a building with a rooftop greenhouse. Using the exhaust gas and the cooling water from …

Diffusion absorption refrigeration (DAR) is a promising cycle with regard to renewable
energy utilization, as the cycle can operate using only a thermal energy input. This study …
