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...

This paper demonstrates the application of exergy to gain a better understanding of coal properties, especially chemical exergy and specific chemical exergy. In this study, a BASIC computer program was used to calculation of the chemical exergies of the coal-based fuels. Calculations showed that...
