An assessment of solar-powered organic Rankine cycle systems for combined heating and power in UK domestic applications

Abstract: h i g h l i g h t sA domestic-scale combined solar heat and power (CSHP) system is simulated in the UK climate. The CSHP system comprises a solar collector array, an ORC engine and a hot-water cylinder. An exergy analysis, parametric study and annual performance assessment are performed. An average electrical power of 89 W plus an 86% hot water coverage are demonstrated. A total system cost as low as £2700 and a levelised cost electricity of 44 p/kW h are reported. a b s t r a c t Performance calculations are … Show more

“…The 2013 capacity of this country to use solar water heating technologies accounted for 3.3% of the global market, and since then it has had the largest number of new installations throughout the European Union. While in Europe considerable progress has been recently made in the development of organic Rankine cycle (ORC) systems for small-scale power generation from solar energy, in Romania the level of installation of simple solar water heating systems is the lowest in Europe [41,42]. Table 1 shows that Romania ranks 7th in terms of the number of inhabitants out of the 31 countries listed.…”

“…In this case, it was shown previously (Perers 1997;Schnieders 1997;Chow 2003;Fischer et al 2004;Dumont, Quoilin, and Lemort 2014;Freeman, Hellgardt, and Markides 2015) that the dynamics of the reversible unit can be neglected because of its small inertia compared to other sub-systems.…”

“…Small-scale SORC system studies [22,23] show that R245fa (1,1,1,3,3-pentafluoropropane) refrigerant has good performance in low and medium heat source temperatures; therefore, R245fa refrigerant was selected as the working fluid. For stable and continuous system operation, the pressure ratio of three was applied (the adopted pressure ratio is relatively low compared to other small-scale SORC studies [22][23][24][25]). The remaining thermal energy in the thermal storage after sunset was used for additional power generation.…”
