Design study of configurations on system COP for a combined ORC (organic Rankine cycle) and VCC (vapor compression cycle)

Thermodynamic analysis of a combined organic Rankine cycle and vapor compression cycle system activated with low temperature heat sources using low GWP fluids

“…Compared to other thermally activated cooling technologies, a vapor compression cycle (VCC) powered by an organic Rankine cycle (ORC) has the advantage of making use of the heat source throughout the year [13] to provide either cooling or electricity when cooling is not required [14], increasing the annual operating hours of the system and improving the economical profitability. Combined ORCeVCC systems in previous publications have used various working fluids: chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs) [15,16].…”

Performance analysis of a novel system combining a dual loop organic Rankine cycle (ORC) with a gasoline engine

“…Teng et al studied a supercritical organic Rankine cycle system for recovery of waste heat from heavy-duty diesel engines [8]. The performance of a novel, thermally activated system combining an ORC with a vapor compression cycle for vehicular engine waste-heat recovery was studied by Little and Garimella [9], Wang et al [10], and Wang et al [11]. Guo et al investigated the performance of a novel cogeneration system that consisted of a low temperature, geothermallypowered ORC subsystem, an intermediate heat exchanger subsystem, and a heat pump subsystem [12,13].…”

Thermal analysis of a Phase Change Material for a Solar Organic Rankine Cycle

“…This low-temperature heat can be obtained from various sources, like a gas turbine or an internal combustion engine [1][2][3][4][5][6][7]. ORCs can also be coupled with environmentally friendly renewable energy sources (RES), such as solar.…”
