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...

In this paper solar assisted heating and absorption cooling system and domestic hot water needs for a hotel having fifty rooms in Antalya have been investigated. First of all, solar radiation and meteorological data for Antalya and heating and cooling loads of the hotel building are given. For the heating cycle, active systems using liquid as the working fluid; and for the cooling cycle, solar-...

Combined cooling, heating, and power (CCHP) systems enable the simultaneous supply of electricity, thus meeting major energy needs humans in a single device. Conventional CCHP consist combination prime mover, cooling system, each them operating with thermodynamically suitable working fluid. Recently, novel cycles, based on use fluid for whole operation, have been proposed. Since choice represen...

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...

Gas turbines play an important role in supplying power for the country especially in peak electricity load. The main disadvantages are the turbines, they produce large changes are a result of climate change. However, in times of peak electricity grid and at the same time warm months, can produce gas turbines under the effect of ambient temperature, the amount of reduced considerably. The method...
