Cooling and refrigeration systems consume around 17% of the worldwide electricity. Enhancing the performance of these systems, using renewable energy resources and waste heat recovered from industrial processes, will lead to reduced fossil fuel consumption. Improvements of these systems using ecofriendly working fluids are of equal importance. Both options contribute to the minimization of the emissions of greenhouse gases and ozone depletion substances. In this paper, a detailed and comprehensive review of the innovative and improvement approaches of the thermo-mechanical refrigeration (TMR)

“…The fixed variables for both setups are the same as shown in Table 2. The working fluid R365mfc (Version, Company, City, State abbreviation if USA and Canada, Country) has already been used for high temperature heat pump applications [25,40] as well as in ORCs [41]. Due to these existing experiences in both systems this fluid has been selected.…”

Reversible Heat Pump–Organic Rankine Cycle Systems for the Storage of Renewable Electricity

et al. 2018

Storage of electricity from fluctuating renewable energy sources has become one of the predominant challenges in future energy systems. A novel system comprises the combination of a heat pump and an Organic Rankine Cycle (ORC) with a simple hot water storage tank. The heat pump upgrades low temperature heat with excess power. The upgraded heat can drive an Organic Rankine Process using the heat pump in reverse operation mode. This approach allows a comparably efficient storage of excess electricity. Waste heat sources usually do not qualify for electricity production even with ORC processes due to low temperatures. Upgrading the temperature of the waste heat by means of excess electricity makes the use of an ORC feasible in order to recover the electricity input. Thermodynamic cycle simulations with IPSEpro software outline that the process provides power-to-power efficiencies in a range of 50% for small-scale applications based on commercially available heat pump components. The isentropic efficiency of compressors/expanders plays a crucial role on the system performance. Applications of the proposed cycle in the megawatt range with more efficient turbines and dynamic compressors will therefore increase the power-to-power efficiency to above 70%.

“…Three different adsorption pairs for the topping cycle and three working fluids for the bottoming cycle were selected separately. Comparisons of their efficiencies showed that ORC had a great potential to reclaim low-grade heat energy [12]. Sadeghi et al, developed three configurations of ORC powered by a geothermal source, including the simple ORC, the parallel two-stage ORC and the series two-stage ORC.…”

Closed-Loop PI Control of an Organic Rankine Cycle for Engine Exhaust Heat Recovery

et al. 2020

View full text Add to dashboard Cite

The internal combustion engine (ICE) as a main power source for transportation needs to improve its efficiency and reduce emissions. The Organic Rankine Cycle (ORC) is a promising technique for exhaust heat recovery. However, vehicle engines normally operate under transient conditions with both the engine speed and torque varying in a large range, which creates obstacles to the application of ORC in vehicles. It is important to investigate the dynamic performance of an ORC when matching with an ICE. In this study, the dynamic performance of an ICE-ORC combined system is investigated based on a heavy-duty diesel engine and a 5 kW ORC with a single-screw expander. First, dynamic simulation models of the ICE and the ORC are built in the software GT-Power. Then, the working parameters of the ORC system are optimized over the entire operation scope of the ICE. A closed-loop proportional-integral (PI) control together with a feedforward control is designed to regulate the operation of the ORC during the transient driving conditions. The response time and overshoot of the PI control are estimated and compared with that of the feedforward control alone. The results based on the World Harmonized Transient Cycle (WHTC) indicate that the designed closed-loop PI control has a shorter response time and a better trace capacity during the dynamic processes. The average output power and thermal efficiency during the WHTC cycle are improved by 3.23% and 2.77%, respectively. Compared with the feedforward control alone, the designed PI control is more suitable for practical applications.
