Abstract The problems of energy shortage and ecological destruction are becoming increasingly serious. As a comprehensive utilization system, cogeneration system has gradually become research hotspot. In order to improve the basic frequency stability reduce operation cost, this paper presents multi-energy coordinated control method for CHP micro-grid. Firstly, topology CCHP is analyzed. On basi...

Cold climate air-to-air heat pumps (CCHP) offer a strong potential for energy use reductions in Canadian homes. Proper selection of the unit is critical order to take advantage improved efficiency and increased capacity at low ambient temperatures ability modulate meet wide range heating loads. A new performance rating procedure (CSA EXP07) was developed better represent seasonal CCHP systems v...

Significant research efforts are directed towards finding new ways to reduce the cost, increase efficiency, and decrease environmental impact of power-generation systems. The poly-generation concept is a promising strategy that enables development sustainable power system. Over past few years, Proton Exchange Membrane Fuel Cell-based Poly-Generation Systems (PEMFC-PGSs) have received accelerate...

In this paper, using parabolic mirrors, a solar field was designed, which was related to a storage tank for a residential complex in the city of Tafresh located in the center of Iran. The design was performed for the existing oils: VP1, THERMINOL 66, THERMINOL 59. Finally, considering an organic cycle with R123 as working fluid and assuming a minimum length required for oil flow rate to reach a...
