As traditional microstrip antenna has the disadvantage of narrow bandwidth, a kind of adaptive differential evolution algorithm based on dual population has been put forward, in combination with RWG-SWG hybrid basis function integral equation, to optimize and design a wideband antenna. In the algorithm, one population as a development and another population as a probe are used to increase the diversity...
The economic benefits of building cooling heating and power (BCHP) system are closely dependent upon its design and operation strategy. In this paper, a solar BCHP system which integrates solar facilities with traditional BCHP system is proposed to reduce the operation energy cost. The energy flow and operation strategy of the novel system are analyzed. Relative payback period (RPD) is employed to...
The technical, economical and environmental performances of combined cooling, heating and power (CCHP) system are closely dependent on its design and operation strategy. This paper analyzes the energy flow of CCHP system and deduces the primary energy consumption following the thermal demand of building. Three criteria, primary energy saving (PES), annual total cost saving (ATCS), and carbon dioxide...
