Achieving solutions to environmental problems that we face today requires long-term potential actions for sustainable development. In this regard, renewable energy resources appear to be the one of the most efficient and effective solutions. So clean, domestic and renewable energy is commonly...

Palmitic acid (PA, 59.8°C) and lauric acid (LA, 42.6°C) are phase change materials (PCM) having quite high melting temperatures which can limit their use in low temperature solar applications such as solar space heating and greenhouse heating. However, their melting temperatures can be...

The purpose of this study is to evaluate the chemical exergy (eCH), the higher heating value (HHV) and the lower heating value (LHV) of liquid products obtained from catalytic fast pyrolysis of hazelnut cupulae. In this study, the first and the second law of fast pyrolysis products of a biomass...

Thermal performance and phase change stability of myristic acid as a latent heat energy storage material has been studied experimentally. In the experimental study, the thermal performance and heat transfer characteristics of the myristic acid were tested and compared with other studies given in...

The influence of expanded graphite (EG) and carbon fiber (CF) as heat diffusion promoters on thermal conductivity improvement of stearic acid (SA), as a phase change material (PCM), was evaluated. EG and CF in different mass fractions (2%, 4%, 7%, and 10%) were added to SA, and thermal...

Energy is an essential factor to achieve sustainable development. So, countries striving to this end are seeking to reassess their energy systems with a view towards planning energy programmes and strategies in line with sustainable development goals and objectives. As would be expected, the...

In order to investigate the performance of air-to-air heat pumps for residential heating in the Black Sea region of Turkey, an experimental set-up was constructed. An electrically driven air-to-air heat pump was used for heating a laboratory building with a floor of 75 m2. In this study, a...

Simulations have been made with SOLSIM (Howell, J. R. et al., Solar-Thermal Energy Systems. McGraw-Hill, New York, 1982) for solar and air-source heat-pump systems with energy storage in encapsulated phase-change material (PCM) packings. An experimental study was performed for a laboratory...
