“…Bu et al [7] uses both the cycles with same working third and R123 was regarded as good refrigerant for their system. Wang et al [8] used free piston expender compressor to join ORC and VCC system for easy mechanical design and to stop transmission loss. And this system achieved cooling temperature of 0 o C with thermal energy as low as 60 o C. Nan Zhang et al [9] investigated theoretically solar powered ORC-VCC cooling system working between temperature range -5 o C and 50 o C, and found suitable working fluid for their system is R600.…”

Cooling sector is highly dominated by conventional vapour compression system which have negative effect on environment. The solar rankine cooling system which runs on renewable energy and with environmental working fluids. Solar rankine system consists of two cycles, one is power cycle and another is cooling cycle. Power cycle is either solar rankine cycle or organic rankine cycle(ORC) and cooling cycle is vapour cooling cycle(VCC). To optimize the system there are some modification discussed in this paper. Solar heat source are widely available, so solar energy as a heat source for generator is an good option. This paper covers the basic rankine cooling system and modification in rankine cooling system to enhance the performance of system. But this cooling system still needed lots of work and research to make it as an alternative to conventional cooling system.

“…Additionally, with emphasis on environment, R1234yf was indicated optimal from a thermo-economic approach by Yang et al [7]. Experimental results with efficiencies approaching 80% with scroll expander by Wang et al [8], 70% with screw expander by Zhang et al [9] and 65% with piston expander by Seher et al [10] have been presented. Furthermore, the trucking sector is integrating prototypes to address issues relating to durability, packaging and controls [11].…”

Abstract. Waste heat to power conversion using Organic Rankine Cycles (ORC) is expected to play an important role in CO2 reductions from diesel engines. Firstly, a review of automotive ORCs is presented focusing on the pure working fluids, thermal architectures and expanders. The discussion includes, but is not limited to: R245fa, ethanol and water as fluids; series, parallel and cascade as architectures; dry saturated, superheated and supercritical as expansion conditions; and scroll, radial turbine and piston as expansion machines. Secondly, research direction in versatile expander and holistic architecture (NOx + CO2) are proposed. Benefits of using the proposed unconventional approaches are quantified using Ricardo Wave and Aspen HYSYS for diesel engine and ORC modelling. Results indicate that, the implementation of versatile piston expander tolerant to two-phase and using cyclopentane can potentially increase the highway drive cycle power by 8%. Furthermore, holistic architecture offering complete utilisation of charge air and exhaust recirculation heat increased the performance noticeably to 5% of engine power at the design point condition.

“…Though various studies on the scroll-based ORC system have been carried out through modelling and experimental investigations, there are few researches on the system operating characteristics. Wang et al [15] carried out ORC system experimental test and found the isentropic efficiency of scroll expander is in the range of 70% to 84%. Harada [16] found an isentropic efficiency is over 70% for a 1kW e scroll expander using R134a and R245a as working fluids.…”

AbstractAn experimental investigation is performed for an organic Rankine cycle system with different electrical resistive loads. The test rig is set up with a small scroll expander-generator unit, a boiler and a magnetically coupled pump. R134a is used as the working fluid in the system. The experimental results reveal that the resistive load coupled to the scroll expandergenerator unit affects the expander performance and power output characteristics. It is found that an optimum pressure ratio exists for the maximum power output. The optimal pressure ratio of the expander decreases markedly as the resistive load gets higher. The optimum pressure ratio of the scroll expander is 3.6 at a rotation speed of 3450 r/min for a resistive load of 18.6 Ω. The maximum electrical power output is 564.5W and corresponding isentropic and volumetric efficiencies are 78% and 83% respectively.
