Thermodynamic, Exergetic and Thermoeconomic Analyses of Double-Effect LiBr–Water Absorption Refrigeration Systems with a 5 kW High Temperature PEMFC as Heat Source for Data Center Applications

Thermodynamic, exergetic and thermoeconomic analyses were performed on two types of double-effect LiBr–water absorption refrigeration systems (ARS) for use with a 5-kW high-temperature proton exchange membrane fuel cell (HT-PEMFC) as a heat source. Proper temperatures of the high-pressure generator, combined generator and condenser, condenser, absorber and evaporator were determined to meet the requirements of constant cooling demands for data center operations. The heat balance of the combined unit of generator and condenser in the industrial double-effect LiBr-water ARS is important for determining the flow rate of the primary vapor refrigerant from the high-pressure generator. The industrial double-effect ARS system, whose analysis has not been studied analytically, outperformed the series double-effect system and provided 6.5 kW of cooling capacity with a coefficient of performance of 0.99. The unit cost of chilled water estimated by the modified productive structure analysis (MOPSA) method is approximately 7.18 USD/GJ (=0.026 US$/kWh). Effective exergetic efficiency of HT-PEMFC with the industrial ARS increases to 57.6% from 47.0%.

Thermodynamic analysis and optimization of variable effect absorption refrigeration system using multi-island genetic algorithm

Low efficiency is one of the major concerns associated with absorption refrigeration cycle (ARC). The performance of ARC is affected by internal parameters such as the solution distribution ratio and the generator outlet solution concentration, especially to the absorption-generation heat exchange (AGX) LiBr–water variable-effect ARC. Therefore, the performance of the AGX variable-effect ARC was optimized and analyzed. AGX variable-effect ARC thermodynamic model has been implemented in Engineering Equation Solver (EES). Operation parameters including temperatures of all the units of ARC, solution distribution ratio, and generator outlet solution concentration had been optimized. The effects of the solution distribution ratio and generator outlet solution concentration on constraint conditions, coefficient of performance (COP), exergy efficiency (ηex), and operating range had also been analyzed. Multi-island genetic algorithm (MIGA) was used to optimize the solution distribution ratio and generator outlet solution concentration. The results showed that the optimal COP for the AGX cycle was from 0.885 to 1.249 for THG from 95 °C to 140 °C. The optimized COP was increased by 10.65% on average and 45.49% on maximum, compared with the COP obtained at the same temperature. The MIGA optimization method had proven to be an effective and robust tool that could be utilized to the optimization of AGX variable-effect ARC.

Comparison of experimental performance of absorption refrigeration cycle using NH3/LiNO3+H2O working fluids with different water component proportions

Regarding the working fluids of absorption refrigeration systems, compared with the binary ammonia/water or ammonia/salt solution, the ternary ammonia/lithium nitrate+water solution has some advantages including small viscosities, good heat-transfer efficiency and low crystallization risk. In this paper, four kinds of NH3/LiNO3+H2O solutions with different water component proportions are selected as working fluids, which is No.1(9.6%) < No.2(18.6%) < No.3(27.6%) < No.4(36.9%), and the experimental performance evaluation was conducted on a prototype of absorption refrigeration system driven by exhaust heat. First, experimental tests were carried out with varying operating conditions to evaluate their influences on performance parameters; the detailed experimental parameters operating with No.2 and No.4 working fluids are presented, and the reasons of the experimental results are explained. Then, the experimental results of four ternary working fluids and binary working fluid were compared and analyzed to evaluate the influences of water mass fraction. Compared with NH3/LiNO3, the cooling capacities of No.1, No.2, No.3, No.4 increased by 10.6%, 17.8%, 24.8%, 26.4%, respectively; the logarithmic mean temperature difference of the solution heat exchanger decreased by 1.2 K, 2.0 K, 2.6 K, 3.9 K, respectively. The comparison results indicate that, for the working fluid with larger water mass fraction, it has better heat and mass transfer characteristics, the system can produce larger cooling capacities and has lower required driven temperatures of heat sources, but the overall coefficients of performance hardly changed with the water mass fraction. The experiments and comparison results provide significant references in practical applications for the selection of working fluids of the absorption refrigeration systems.

Numerical investigation on thermal performance of absorption refrigeration system using MWCNT nanoparticle-enhanced 1-hexyl-3-methylimidazolium cation-based ionic liquids

• Specific heat of HMIM cation based four different ionic liquids were investigated experimentally. • Increase concentration in the MWCNT nanoparticle enhanced ionic liquid improves the COP of the ARS. • The largest COP is presented by 1 wt% MWCNT [HMIM][Pf 6 ] NEIL, followed by 1 wt% MWCNT [HMIM][Tf 2 N] NEILs. In this investigation, the thermal performance of single-stage absorption refrigeration systems (ARSs) utilizing different MWCNT nanoparticle-enhanced 1-hexyl-3-methylimidazolium (HMIM) cation-based ionic liquids with R1234yf refrigerant were analyzed. The specific heats of the various MWCNT nanoparticle-enhanced [HMIM] cation-based ionic liquids were obtained experimentally at a temperature and a concentration of 303–383 K and 0–1 wt%, respectively, and were subsequently used for modeling the solubility and absorption refrigeration cycle. As a result, the maximum specific heats of all considered ionic liquids were examined at the highest temperature of 383 K. The solubility order of R1234yf refrigerant from highest to lowest was [HMIM][Bf 4 ], [HMIM][Pf 6 ], [HMIM][TfO], and [HMIM][Tf 2 N] RTILs. In addition, the maximum COPs of the ARSs were achieved at the temperature and concentration of 363 K and 1 wt%, respectively, which were 0.205, 0.242, 0.286, and 0.259 for the [HMIM][Bf 4 ], [HMIM][TfO], [HMIM][Pf 6 ], and [HMIM][Tf 2 N] MWCNT NEILs, respectively. By applying the proposed system could be simplified at high-temperature applications and prevent undesirable side effects of conventional working pairs such as metal incompatibility, toxicity, and chemical instability.

HEAT AND MASS TRANSFER CONSIDERATIONS IN THE DESIGN OF A COILED ABSORBER FOR AMMONIA-WATER REFRIGERATION SYSTEM

The performance of the absorber significantly affect the overall efficiency of any absorption refrigeration system. One of the major reasons for the poor design of the absorber for ammonia-water refrigeration systems is the neglect of mass transfer resistances in the vapour or liquid phase in favour of only heat transfer considerations. Heat removal is critical to the absorption process, however, the ammonia gas is constantly absorbed by the liquid ammonia-water solution. This means that two-phase mass and heat transfer operations take place during the absorption process. Therefore, this implies that, for any proper absorber design, both heat and mass transfer considerations are paramount. Accurate absorber design is further predicated on accurate properties correlations. The correlations required for the absorber design include liquid and vapour enthalpies, saturated vapour pressure, specific heat capacity of water and ammonia vapour, liquid solution dynamic viscosity, liquid solution density, surface tension, liquid solution thermal conductivity, liquid-liquid diffusivity and vapour-liquid diffusivity. Procedures for calculating these parameters have been presented in this paper and their accuracy with previous studies compared. Results showed relatively low percentage deviations and so can be applied for the design and simulation of the absorber. Designs of the absorber for various cooling capacities have been carried in this paper. The variation of ammonia vapour temperatures, liquid ammonia-water solution temperatures, cooling water temperatures, and flow rates of ammonia-water solution and ammonia vapour across the absorber is investigated for the four cooling capacities. For refrigeration systems with cooling capacities of 1 kW, 2 kW, 3 kW and 4 kW, the calculated lengths for a water-cooled coiled absorber are 4.484 m, 8.1467 m, 12.50459 m and 14.78329 m respectively. The calculated overall heat transfer coefficients for the absorption process for the four cooling capacities (1 kW, 2 kW, 3 kW and 4 kW) were 0.4427, 0.4376, 0.4208 and 0.4309 kWm-2K-1 while the mass transfer coefficients were 3.721 x10-9, 4.206 x10-9, 4.556 x10-9and 4.856 x10-9 m2s-1 respectively. Concurrent flow is considered in this study, but the procedure can also be applied to countercurrent flow. KEYWORDS: Absorption Refrigeration, Ammonia Water Heat and Mass Transfer, Design

A variety of vaccines of Covid 19 have been developed by different drug makers. Each vaccine brand requires different storage temperature ranged from 2-8°C, which then requires a cold storage box. In Indonesia, vaccine transportation and storage become big challenges to ensure the vaccines in good condition before use. This research focused to find out the possibility of using geothermal energy from Lahendong geothermal power plant unit 5 in Tompaso, North Sulawesi, for 5 liters-cold storage for Covid-19 vaccine using ammonia-water absorptive refrigeration and to identify the possible temperatures for storage of vaccine. Based on the absorption refrigeration system calculation, the current study found that the average evaporator temperature is 3°C, with cooling load of 1.03 kW and COP of 0.43. This cooling load requires a brine of 59.98 kg/s from the Lahendong geothermal power plant.

Mini cold storage using the parabolic solar trough: An appropriate technology for perishable agricultural product

Limited storage of perishable agricultural products is a common problem for small-scale farmers. Therefore, our approach for this problem is to develop a low operating cost mini cold storage using solar energy. The integration of solar thermal energy with vapor absorption refrigeration systems was studied. In vapor absorption systems, heat energy is taken as the source of input energy and the performance characteristics depend on heat energy supplied and pump work used. The novelty of our project is that it uses a parabolic solar heat collector to run a vapor absorption refrigeration system using heat energy extracted from solar energy. In this cyclic process, the refrigerating effect is produced. By utilizing this mini cold storage system, tomatoes can be stored for four weeks whereas, with room temperature storage, it only lasts one week. This appropriate technology promises small-scale farmers to keep their perishable agricultural products for several weeks without additional storage costs.

Analysis of a newly developed locomotive engine employing sustainable fuel blends with hydrogen

Transportation emissions from fossil fuels and low efficiency engines significantly contribute to global warming. One way to mitigate this is to develop more efficient engines and use sustainable fuels. This paper presents a novel hybrid locomotive engine to replace the EMD 16-710G3 engine used for Canada’s rail transportation. It consists of a gas turbine instead of an internal combustion engine, solid oxide fuel cell with steam reformer and water gas shift reactor, and thermoelectric generator and absorption refrigeration system for energy recovery, and onboard hydrogen production using aluminum electrolysis cell and proton exchange membrane fuel cell. The used fuels are methanol, hydrogen, methane, ethanol, and dimethyl ether rather than diesel fuel. This integrated system is investigated thermodynamically to evaluate the energy performance. The system performance is increased from 40% to 48% and 50% of energy and exergetic efficiencies, while the total power is increased from 3383 kW to 7211 kW using a methane and hydrogen blended fuel. Also, the engine has an efficiency above 60% using a dimethyl ether and hydrogen blend. Using alternative fuels helps reduce CO2 emissions by 50% for the methane and hydrogen blend and more than 70% for the other blends, such as ethanol and dimethyl ether blended with hydrogen. The proposed engine can potentially be applied to improve the overall system performance and reduce the environmental impact.

Simulation of an improved solar absorption refrigeration system with phase change materials

Aiming at the problems of low solar energy utilization rate, poor intermittent, low stability and poor energy saving effect in traditional solar absorption refrigeration system, a lithium bromide-water absorption refrigeration system driven by solar in Tai’an was taken as the research object. An improved solar absorption refrigeration system with phase change was presented. In typical day and whole refrigeration period, the traditional solar absorption refrigeration system with and without phase change were simulated by TRNSYS transient simulation software. Their collector efficiency, unit cooling capacity and COP were comparatively analyzed. The results showed that the collector efficiency of the improved solar absorption refrigeration system with phase change was 4.2% higher than that of the traditional solar absorption refrigeration system without phase change. The unit cooling capacity was 2.8% lower than that of the traditional system, which store the excess cooling capacity with the help of PCMs. The average COP of traditional absorption system and improved solar absorption refrigeration system were 0.737 and 0.679, respectively. This manuscript provides a theoretical basis for the development of solar phase change heat storage absorption refrigeration system.

An innovative integrated CCHP system with water scrubbing‐based biogas upgrading unit and molten carbonate fuel cell

AbstractThe main purpose of this study is to develop an integrated structure of simultaneous generation of electricity and refrigeration as the main product and hot water as a by‐product. This proposed structure consists of a water scrubbing biogas upgrading process, molten carbonate fuel cell (MCFC) unit, gas/steam power (GSP) cycle, and absorption refrigeration (AR) system. In this regard, 10.71 kg/s untreated biogas enters the integrated system and 158,351 kW net power is produced. Wasted heat of the structure is utilized to generate cooling of 253.9 kW at a temperature of 243.6 K by applying the AR system and the rest of the heat is used to generate 8.391 kg/s hot water as the system byproducts. The process integration between the different parts has led to an increase in the thermal efficiency of the whole system so that the electrical and overall efficiencies are 78.68% and 79.86%, respectively. The investigation of the exergy study demonstrates that the exergy destruction of the entire structure is 71,859 kW, of which the turbine/compressor/pump section with 24,700 kW (with a share of 34.37% of the total) and MCFC/reformer section with 22,285 kW (with a share of 31.01% of the total) have the most irreversibility. The exergy efficiency of the hybrid structure is 71.06%. Through a parametric study, the present integrated system in various conditions is assessed. One of the results of main outcomes is the increase of overall efficiency up to 83.39% due to the reduction of inlet biogas methane mole content up to 50%. Rising the methane in inlet biogas, although leading to more production of system products, reduces the efficiencies of various parts of the system, including the MCFC unit and GSP cycle, as well as integrated system total efficiency.

Development of a geothermal plant combined with absorption and Rankine cycles for trigeneration

ABSTRACT A thermodynamic modeling through energy and exergy approaches is performed on a newly developed system for hot water, cooling and electricity production. The geothermal power plant supplies thermal energy to the Rankine cycle to produce hot water and green electricity. The absorption refrigeration system is integrated with the geothermal plant for hot water and cooling. Various parametric studies are conducted to present the exergetic and energetic losses of each subcomponent. The results of the parametric studies indicate that the maximum useful output power of the turbine is obtained as 5991 kW at a geothermal injection temperature of 460 K. Moreover, the highest heat cooling rate of the evaporator is 4397 kW obtained at the inlet mass flowrate to the pump of 30 kg/s. The highest energetic and exergetic coefficient of performance values at inlet temperature to pump of 30°C are 0.584 and 0.287, respectively. Furthermore, the maximum energy and exergy coefficient of performance values at −5°C of the outlet temperature of the evaporator are found to be 0.58 and 0.231, respectively.

Enhancing Benefits by Rectification in the Absorption Refrigeration Systems

The main objective of this article aims to enhance a single stage absorption refrigeration machine, using the ammonia-water pair as working fluid, and this from the improvement of its exergetic performances by means of a vapor rectification system. The rectifier makes it possible to emit a vapor enriched in pure fluid (ammonia) with a high flow rate; this one is thus transformed into condensate after condensation; as it also allows evacuating a liquid (water) in the form of reflux. Moreover, in order to show the role of the rectifier and to highlight its impact on the operation of the proposed installation, the methodology adopted in this work aims to develop a thermodynamic model of numerical simulation using the FORTRAN language according to two approaches. An energetic analysis approach which aims to assess, in a first time, the performance of the studied refrigeration installation. However, the exergetic approach tries to calculate the exergy efficiency, and thus to evaluate the losses of exergies of the refrigeration installation in a second time. Therefore, the obtained results showed a clear improvement in the exergetic efficiency, accompanied against by an optimization of the losses of exergies which are due to the irreversibility of the studied thermodynamic system. The novelty brought by the present study encourages the engineers and manufacturers to realize the future absorption refrigeration machines integrating rectifier systems.

A novel carbon dioxide capture system for a cement plant based on waste heat utilization

A novel carbon dioxide capture system that combines cooling, heating and power (CCHP) based on a cement plant has been developed and evaluated. The proposed integration is realized by recovering the waste heat of cement flue gas to produce electricity for decarburization or sale. The novel system can reduce the expensive external energy consumption for decarbonization by fully utilizing the heat itself. The heat loss of the CO2 capture process is utilized to supply heat directly or provide cooling by an NH3-H2O absorption refrigeration system. An appropriate decarbonization rate (18.89 %) is determined when the income just as much as possible compensates for the cost of decarbonization. The coupled system is assessed from thermodynamic and economic perspectives to exhibit its feasibility. Under the heating mode, 5.52 MW energy is recovered from the decarbonization heat loss. Meanwhile, a total system efficiency of 10.28 % and a total exergy efficiency of 8.18 % can be achieved. Both metrics are superior to the cooling mode, in which 3.66 MW energy is taken into the absorption refrigeration system for suppling 0.82 MW of cooling. Finally, the annual income achieves 3287.07 k$ while the COA as low as 46.31 $/t CO2 under this decarbonization rate.

Exergy and thermoeconomic analyses of the diffusion absorption refrigeration system with various nanoparticles and their different ratios as work fluid

The fact that diffusion absorption refrigeration (DAR) systems can also work with low power plants has increased the interest in these cooling systems again. The DAR systems are mostly analyzed using energy analysis. Although, energy analysis is not adequate itself, so exergy analysis is required. In this study, the effects of nanofluid use on the DAR system performance are investigated by performing exergy and thermoeconomic analyses. Some nanoparticles like MgOAl2O3, ZnOAl2O3 and TiO2 in various weight ratios are used in the DAR system. In experiments with different nanoparticles, the effect of utilizing hybrid nanoparticles on enhancing system performance is also evaluated. The highest exergy destruction rate occurs in the solution heat exchanger, although the lowest exergy destruction rate happens in the condenser. The highest exergy efficiency with 0.798 is found in the base fluid (25% NH3–H2O). Besides, it is clearly observed that exergy efficiency decreased in the DAR systems using nanofluids. Moreover, the economic analysis of the DAR system is added to the study in order to evaluate the relationship between the exergy destruction rate and initial investment costs. It is found that the DAR system with ZnOAl2O3 (2 wt%) is preferable compared to other DAR systems.

A new correlation for performance prediction of small and large capacity single-effect vapor absorption refrigeration systems

Vapor absorption refrigeration (VAR) enables cleaner cooling by exploiting waste or renewable heat, hence avoiding the use of fossil-based electricity employed by conventional chillers. A new correlation is developed for the prediction of the coefficient of performance (COP) of single-effect VAR systems under different operating conditions, considering 27 different working fluids and 1,568 literature data points. The developed correlation incorporates for the first-time fluid parameters such as the boiling points of absorbents and refrigerants, the latent heat of vaporization of refrigerants, and the specific heat of absorbents together with the generator, condenser, absorber and evaporator temperatures. It is further applied for the first time in both small- and large-scale VAR systems, with the former validated based on results from literature and the latter based on ASPEN Plus simulation data, derived from rigorous VAR system models. The small-scale, literature results reveal that the developed COP model is applicable for all data sets with a mean absolute percentage error (MAPE) of 12.25%, for 93.78% of the data that appear within a ± 30% error range. The developed model is also applied to the simulation of large-scale VAR cycles that use ammonia-water (NH3-water) and water-lithium bromide (water-LiBr) for different cooling loads (100 TR, 1000 TR, and 10,000 TR), to evaluate its suitability for high-capacity systems. The maximum MAPE among the model-predicted and ASPEN Plus-generated data is 13.51% for the 100 TR water-LiBr system, with all data found within a ± 30% error band. The developed model can be applied to predict the COP of numerous fluids for single effect VAR cycles, paving the way for the investigation of VAR application in large scale, district cooling systems.

Simulation, energy and exergy analysis of compressed air energy storage integrated with organic Rankine cycle and single effect absorption refrigeration for trigeneration application

Compressed air energy storage (CAES) is increasingly investigated as a viable technology for balancing electricity supply and demand. The main purpose of CAES is to overcome the intermittent problem when renewable energy is introduced. However, the round-trip efficiency (RTE) of the CAES system commercially developed is still low (around 54 %) and requires further improvement. This study proposed a novel combined cooling, heating and power (CCHP) system, which improves the RTE in two ways: (i) organic Rankine cycle (ORC), which recovers the waste heat and produces extra power; (ii) single effect absorption refrigeration, which delivers cooling capacity with further recovery of waste heat from the flue gas. Steady-state process simulation of the CAES system, ORC and single effect absorption refrigeration system was developed in Aspen Plus® software. The proposed system was evaluated through process, energy, and exergy analysis. The effect of various working parameters on the performance of the CCHP system was also analysed. The results indicated that under design condition, the proposed CCHP system can produce about 206 MW electrical energy, 28 MW heating and 0.2 MW cooling capacity. The RTE of the proposed system (at 66.35%) showed an improvement of 12.35% when compared with the CAES system commercially deployed. The overall exergy efficiency is about 51% and the total exergy destruction of the components of the system is 477 MW. The combustion chamber is responsible for more than half of the exergy destruction.

Multivariate inverse artificial neural network to analyze and improve the mass transfer of ammonia in a Plate Heat Exchanger-Type Absorber with NH3/H2O for solar cooling applications

This work presents a numerical approach to compute optimal operating conditions that maximize the absorption flux into a heat exchanger designed for absorption refrigeration systems. Experimental data were obtained from a test circuit that operates in bubble absorption mode with an inner vapor distributor into a Plate Heat Exchanger-type (PHE-type) and interacts with ammonia vapor, NH3-H2O refrigerant, and cooling water. An artificial neural network (ANN) was trained to correlate the thermal properties of the solution and absorption flux in function of easily measurable parameters (concentrations, mass flows, and pressures of saturated and diluted solutions, flow and temperature of the ammonium vapor, environment temperature, and solution temperature). According to results, ANN is adequate to correlate the operational parameters and the transport phenomena inside the heat exchanger with a precision &gt; 99%. ANN also quantitatively identified the ammonium vapor flow (43.1%), dilute solution flow (18.1%), and dilute solution concentration (13.1%) as the variables most importantly in influencing absorption flux optimization. Subsequently, a multivariable inverse artificial neural network was applied to improve the mass transfer into the PHE-type.It was identified that simultaneous optimization of the ammonia and dilute concentration flow rates improves the absorption flow performance by up to 96.3% under a worst-case scenario (ammonia flow rate&lt;1.4 kg/min) and even 7.04% when even when operating near the amino vapor flow limit (ammonia flow rate&gt;2.0 kg/min). Finally, it was confirmed that incorporating the diluted solution concentration into the optimization contributes to improving the performance of the absorption process 1%. Results obtained are relevant in the search to produce more competitive absorption cooling systems, demonstrating the feasibility of improving the performance of heat exchangers without structural modifications. The proposed methodology represents an interesting option to be implemented to improve performance in solar cooling systems.

Performance analysis of a novel compression-assisted absorption power and refrigeration system with selected 1,1-difluoroethane/ionic liquid

Low global warming potential hydrofluorocarbon (HFC)-ionic liquid (IL) mixtures are a promising type of environmentally friendly binary working pair that can overcome the drawbacks of traditional mixtures. To compensate for the high-grade power consumption of its applicable compression-assisted absorption refrigeration systems, a novel combined absorption system with a compression booster for the cogeneration of power and refrigeration (CAPRC) is proposed via this study. The system operates efficiently by utilizing low-grade heat sources in a cascaded manner. It was studied using energy, exergy, and economic analyses with verified models. 1,1-difluoroethane/1-hexyl-3-methylimidazolium bis(triflfluoromethylsulfonyl)imide was first pre-selected from potential working pairs due to its superior thermodynamic properties and highest performances in absorption systems. The performances of the CAPRC under typical space-cooling conditions were then analyzed theoretically for various operating modes and control parameters. Noted in cold mode, CAPRC could produce a constant cooling load by enhancing the utilization of heat sources through the adjustment of compression ratio and expansion ratio, indicating its outstanding adaptability to time-variable low-grade heat sources. The CAPRC could also generate 80.91% more net power than the reference system and offered 12.87% and 10.68% higher effective energy and exergy efficiencies, respectively, under optimized base-case control parameters in dual-output mode. A subsequent sensitivity analysis was conducted to assess its power and cooling production and effective efficiencies under various external conditions. The shortest payback period was finally estimated to be 6.43 years, which is 19.28% less than the reference system, further demonstrating the cost-effectiveness of the proposed system.
