Energy savings of a house with solar heating, earth cooling and air circulation

Zhang, Qingyuan; Ishihara, Osamu; Hayashi, Tetsuo - In: Renewable Energy 5 (1994) 5, pp. 1135-1137

A new type of residence with solar heating, earth cooling and air circulation(the SEA House) has been proposed by the authors. In winter, the house is heated by solar energy. Thermal insulation, heat storage and air circulation are used to maintain the room temperature at a comfortable level and...

A study on a passively heated single-zone building using a thermal storage wall

Khalifa, Abdul-Jabbar N. - In: Renewable Energy 14 (1998) 1, pp. 29-34

The thermal performance of a passively heated zone is predicted by calculating the transient temperature variation of each node in the system using a finite-difference model. The sensitivity of the zone air temperature to the change in some of the zone features is examined. Some of these...

Numerical simulation of the limiting efficiency of the graded bandgap solar cell

Rafat, N.H.; Abdel Haleem, A.M.; Habib, S.E.-D. - In: Renewable Energy 32 (2007) 1, pp. 21-34

The limiting efficiency of the compositionally graded bandgap solar cell is calculated using a 1-D numerical simulator. Our simulator calculates the limiting efficiency by solving the coupled semiconductor equations, namely, Poisson's equation, the current continuity equations, together with the...
