“…As the combined cooling, heating and power system can improve the solar energy utilization ratio and match solar energy supply and energy use, it has attracted the increasing research interests. While most of the present studies referred to large scale plants [21], which were relatively mature technologies [22], a few researches focused on small-scale CCHP systems, for example the small-scale ORC expander [23], the solar micro-CCHP based on dual-ORC [24], the small-scale concentrated solar combined heat and power system [25], the domestic scale solar-powered ORC and vapour compression cycle coupled system [26]. Small-scale systems were considered a relatively more suitable solution for building applications [27].…”

This paper aims to present a comparative study into the cascade and series configurations of the organic Rankine cycle based small-scale solar combined cooling, heating and power system for civil application. The energy performance of the systems is studied by developing a thermodynamic model. The simulation model is validated using the literature results. Analyses of the research results indicated that the cascade system can achieve maximum value of the primary energy efficiency of 13.4% for cooling and power generation under solar collecting temperature of 115 °C in cooling mode. The cascade system has more cooling output and less electricity output in cooling mode compared with the series system. In heating mode, the single solar organic Rankine cycle (ORC) operation can achieve highest primary energy efficiency of 19.6% for heating and power generation under solar collecting temperature of 100 °C. Systems with R141b as ORC working fluid show better performance than those with R123 and R1233zd(E).

“…It is expected to increase the energy consumption in 44% from 2006 to 2030 (GONZALEZ, GRÁGEDA, AND USHAK, 2017). There are some environmental friendly alternatives to fossil fuels that are abundant, like solar energy, wind energy and biomass (BELLOS and TZIVANIDIS, 2018;FERTAHI et al 2018;ISLAM et al 2018). In some cases it can be used as an alternative to reduce the fossil fuel consumption and in other cases those natural resources could be the only choice for rural areas, for example (WaNG, GUAN and WU 2017).…”

projeto de extensão com decorrências no contexto contemporâneo de consumo. Para isso, foi realizada uma análise por meio das confluências entre a literatura e o arsenal documental do projeto para sua caracterização extensionistas. Observou-se, a partir da pesquisa, que o Clube de Trocas tem possibilitado a ressignificação do consumo e a mitigação de suas consequências, pautando assim a construção de uma nova epistemologia benéfica e solidária. Além disso, o mesmo tem se apresentado como um espaço potencial para a formação coletiva que propicia a experimentação e a vivência de outra dinâmica de consumo, direta, critica e socializadora.

“…environmentally friendly, and viable alternatives to conventional fossil fuels. 7 Although the application of solar energy is limited due to regional factors and intermittency, its utilization in the field of power generation and heating helps solve energy and environmental problems. Numerous theoretical and experimental studies for solar energy have been conducted because there is tremendous potential for solar energy to meet energy demands if the collection technology is readily mature.…”

Summary A novel heat pump and power generation integration system (HPPGIS) using solar energy as a low temperature heat source was presented in this study. This system could be operated in both an organic Rankine cycle power generation (ORC‐PG) mode and a reverse Carnot cycle heat pump (RCC‐HP) mode. Compared with a single heat pump and power generation system, this system improved the utilization efficiency of solar energy, thus showing potential for the generation of economic benefits. Contrastive analyses of different working fluids using ORC‐PG and RCC‐HP systems were conducted first, leading to the selection of R142b and R245fa as optimal fluids. Then, an experimental investigation of the system was carried out under different conditions. A heat pump and ORC system model was proposed and validated by comparing experimental and simulated values. The experimental results indicated that the HPPGIS had good feasibility and stability in both modes. In the ORC‐PG mode, HPPGIS had a power output of 1.29 kW and a thermal efficiency of 4.71% when the water inlet temperature of the evaporator was 90.03°C. In the RCC‐HP mode, HPPGIS had a COP of 3.16 and a heat capacity of 33.24 kW when the water outlet temperature of the condenser was 106.23°C.
