In the present study, a thermodynamic model is proposed to analyze and assess the performance, through energy and exergy, of a cascade active magnetic regenerative (AMR) refrigerator operation a regenerative Brayton cycle. This cascade refrigeration system works with Gd x Tb 1–x alloys as magnetic materials where the composition of the alloy varies for different stages. In this model, the heat transfer fluid considered is a water– glycol mixture (50% by weight). The refrigeration capacity, total power consumption, coefficients of performance (COP), exergy efficiency and exergy destruction rate of a cascade AMR refrigeration (AMRR) system are determined. To understand the system performance more comprehensively, a parametric study is performed to investigate the effects of several important design parameters on COP and exergy efficiency of the system.

Abstract:
In the mechanical cutting process, the replacement of traditional cutting solution with cold air can avoid the pollution of environment. In order to high efficient the refrigerating device and flexible adjust the temperature of cold air, it is necessary to use cascade refrigeration system to supply cool quantity for the compressed air. The introduction of a two-component non-azeotropic mixing refrigerant into the cryogenic part of the cascade system, can effectively solve the problems of the system working at too high pressure and the volume expanding of refrigerant in case of the cascade refrigeration sets closed down. However, the filling ratio of mixing refrigerants impact on the relationships among the closing down pressure, refrigerating output and refrigerating efficiency. On the basis of computing and experiment, the optimal mixing ratio of refrigerant R22/R13 and a low temperature of -60° were obtained in this study. A cold air injecting device possessing high efficiency in energy saving has also been designed and manufactured. The cold air, generated from this cascade system and employed in a cutting process, takes good comprehensive effects on machining and cutting.

Abstract:
Cascade cooling systems containing different cooling methods (e.g., air cooling, water cooling, refrigerating) are used to satisfy the cooling process of hot streams with large temperature spans. An effective cooling system can significantly save energy and costs. In a cascade cooling system, the heat load distribution between different cooling methods has great impacts on the capital cost and operation cost of the system, but the relative optimization method is not well established. In this work, a cascade cooling system containing waste heat recovery, air cooling, water cooling, absorption refrigeration, and compression refrigeration is proposed. The objective is to find the optimal heat load distribution between different cooling methods with the minimum total annual cost. Aspen Plus and MATLAB were combined to solve the established mathematical optimization model, and the genetic algorithm (GA) in MATLAB was adopted to solve the model. A case study in a polysilicon enterprise was used to illustrate the feasibility and economy of the cascade cooling system. Compared to the base case, which only includes air cooling, water cooling, and compression refrigeration, the cascade cooling system can reduce the total annual cost by USD 931,025·y−1 and save 7,800,820 kWh of electricity per year. It also can recover 3139 kW of low-grade waste heat, and generate and replace a cooling capacity of 2404 kW.

Abstract:
NH3/CO2 cascade refrigeration system is recognized one of the most promising technologies in low-temperature application. In this paper, a NH3/CO2 cascade refrigeration system with subcooling in low-temperature circuit driven by recovery expansion work has been proposed. The aim of this study is to investigate the proposed cascade refrigeration system compared with conventional cascade refrigeration system. Mathematical models based on energy conservation and exergy balance are established. The selection of different refrigerants in auxiliary subcooling system is discussed. The effects of operating parameters such as the condensation temperature of the low-temperature circuit, evaporation temperature, and expander efficiency on system performance are evaluated. The results show that the coefficient of performance and exergy efficiency of the proposed system are about 7.56% and 7.98% higher than that of conventional cascade refrigeration system. The discharge temperature of NH3 compressor can be significantly reduced by 18.33%. The isentropic efficiency of the expander has a large impact on the system performance.

Abstract:
The investigations focus on load shifting, load clipping and energy efficiency through control strategies. Load shifting is achieved by increasing the amount of work done in the Eskom non-peak period. This then results in a decrease in the Eskom peak time work load. The mine refrigeration system is modelled and verified with the data. A simulation is made from the model and the simulation is used to develop the new control strategy and new operational parameters. Predicted results are verified to be within production operational constraints. A case study was carried out to prove the effectiveness of the newly developed control strategy and operational parameters. Firstly the cascade mine surface refrigeration system is automated to allow remote viewing and control of the system from a central point. The control strategy is tested through implementation on automated mine refrigeration systems. The real-time energy management system (REMS) is set up and the communication with the SCADA is tested through observing dam level temperatures and stopping and starting refrigeration machines. The decisions the controllers make are monitored until the system is fully automated. The results of the new control system on the flows, temperatures, dam levels, thermal energy and electrical energy are validated and verified. An assessment of the case study proved that DSM can be done on cascade mine refrigeration systems. A 4.2 MW load shift was predicted and research found an over performance of 0.3 MW. It is clear from the results that utilising the thermal storage in cascade mine surface refrigeration systems, will allow DSM load shifting. In general, this dissertation proved DSM can be done on refrigeration systems and it is recommended that further studies be done on underground mine refrigeration systems.

Abstract:
Nowadays traditional (direct expansion) supermarket refrigeration systems are mostly employed in supermarket establishments for refrigerating food products and beverages in the store. However, the installations of long piping system, fittings and joints in traditional systems are causing substantial refrigerant losses. The refrigerant losses in turn bring about cost and high environmental damage in terms of ozone layer depletion and global warming potential. Additionally, defrosting of air-coils is one of the most energy consuming processes in supermarket refrigeration systems due to susceptibility of the air-coils to moisture. Hence, the frost forming on air-coils as a result of moisture transfer should be removed to keep display cabinets under the required temperature. Various studies, though limited in scope, have been conducted both numerically and experimentally by several researchers in order to provide efficient and environmentally friendly supermarket refrigeration technologies. Empirical and mathematical expressions have also been continuously developed to quantify frost characteristics on flat plates and round tubes thereby determining the appropriate defrost periods. Cascade and secondary coolant refrigeration systems are the potential candidates to replace traditional ones due to the fact that the former can work on natural refrigerants and the latter essentially eliminates long connecting lines and environmentally damaging refrigerants. Development of empirical correlations for frost characteristics on real heat exchangers could also provide accurate prediction of defrost periods thereby eliminating unnecessary waste of energy and deterioration of food products. The current study, therefore, presents (a) mathematical expressions for carbon dioxide-ammonia (R744-R717) cascade refrigeration system; (b) mathematical expressions for frost property and air pressure drop; and (c) a numerical model for medium-temperature secondary coolant system incorporating the new frost property correlations. The thermodynamic analysis of the cascade refrigeration system is useful for the supermarket refrigeration industry to optimize the design and operating parameters of the system. The development of the frost property correlations from experiments on a lab-scale flat-finned-tube heat exchanger is also useful for the supermarket refrigeration industry for better prediction and control of defrost periods and duration for medium temperature air-coils. The medium-temperature secondary coolant model adopted the most appropriate heat transfer, mass transfer and pressure drop correlations obtained from the open literature. The system components such as air-coil, plate heat exchangers, distribution lines, coolant pump and compressor were modeled independently. Each component model was validated and linked to form a complete overall medium-temperature secondary coolant refrigeration system model. The experimental results showed that COP of the Monopropylene glycol/water based medium temperature secondary coolant refrigeration system could be 1.33, whereas the simulated results on a typical supermarket showed that COP of the system could be as high as 1.75. The fundamental difference between the existing secondary coolant models and the current one is that frost characteristics have been incorporated in the air-coil model. In addition to this, complete independent models have been developed for plate heat exchangers based on their respective applications. Hence, the main advantage of the current medium-temperature secondary coolant refrigeration system model is that defrost periods and time span required to defrost frosted air-coils can be accurately determined to achieve energy savings and prevent product deterioration in the display cabinets. The plate heat exchanger models can also enable one to reasonably determine pressure drops thereby leading to an appropriate coolant pump selection. Finally, a step-by-step exercise of the application of the secondary coolant model, which has been included in this project, can be used to completely design, select, evaluate and install such systems or retrofit the existing traditional direct expansion refrigeration systems in supermarkets.

The Cryogenic systems use cascade system, thus reducing the compression ratio. As the volume of the compressors in two stages is decreased, the wasted work is reduced relatively, so that the energy can be saved, and the system operating temperature can be reached easily. Therefore, this study used the cascade refrigeration system available on the market for hardware design, control strategy and refrigerant collocation, in order to meet the appropriate operating conditions of this system design. Due to the faults of the original system compressor and control circuit, the compressor with similar discharge capacity was used instead, and the board circuit was replaced by traditional circuit. The hot section refrigerant A+B and cold section refrigerant A+B were filled in, so that the cascade system could meet the required temperature and stability. After the refrigeration system was completed. The chamber temperature was cooled to setting value, and then tested the performance of the system under the stable and maintained chamber temperature. The load was increased at the chamber temperature of -60℃, -70℃, -80℃ and -80℃ for testing. Afterwards, the temperature and pressure data in two hours stable operation were taken and the pressure-enthalpy chart was drawn to calculate the performance of refrigeration system. The results showed that the performance of cascade system in operation at -60℃ was 2.31, the performance at -70℃ was 1.07, the performance at -80℃ was 0.84 and the performance with additional load at -80℃ was 1.78, however, considering the time required in the process of cooling to -80℃ the cascade system performance was 0.33.

Low-temperature storage refrigeration system is vital for much industry range. The traditional single-stage vapor compressor system is not suitable for low-temperature system; therefore, it should be used through cascade refrigeration system. For many years, as a result of environmental protection issue related global warning and depletion of ozone layer caused by the use of synthetic refrigerants (CFC’s, HCFC’s and HFC’s), the return to the use of harmless natural substances is a must to alternative refrigerants in refrigeration systems. Ammonia (R717) and Hydrocarbon refrigerant have excellent thermodynamic and thermo-physical properties; they can be used in a wide range of refrigeration system. In this paper, a cascade refrigeration system with Ammonia (R717) and Hydrocarbon refrigerant (HC) as working fluids in the low and high temperature stages, respectively, has been analysed and compared with R22 and R134a of traditional refrigerant.

This paper examines how the common refrigerant R-134a and the non-azeotropic refrigerant R-404A perform in a binary refrigeration with the addition of a refrigerant precooler and a desuperheater and the changes in the system with the added refrigerants before and after subcooling through experiments and comparison. Inferences are made on the viability of installing a ‘refrigerant precooler’ in the refrigerant system through theoretical analysis of changes in the coefficient of performance (COP) of the system in the subcooled and superheated states. The purpose is to understand how the binary refrigeration system performs in terms of actual operation and system performance in the different models designed for this study and examine the possibility to optimize the ‘refrigerant precooler and desuperheater combination’ developed in this study based on the data obtained. Analysis of the data obtained from this experiment reveals that the addition of a heat receiver at the outlet of the compressor in a refrigerated vehicle can effectively control the degree of subcooling of the drainage pipe in the condenser at below 38℃ and the addition of a refrigerant precooler improves problems such as unstable refrigerant temperature rise in the refrigerated vehicle after evaporator pump-down and shutdown, thereby increasing the refrigeration speed. An analysis that compares the model in which both additional components are synchronized with the basic model shows that with the power consumption of the binary refrigeration system as the baseline, adding only the desuperheater, only the precooler, and the desuperheater and precooler combination achieves energy efficiency of 24%, 54.3% and 57.8%, respectively. Therefore, the addition of the desuperheater and precooler combination to the binary refrigeration system can effectively improve overall performance and reduce carbon emissions.

The objective of this research is to design a auto-cascade refrigeration system with zeotropic refrigerant mixtures R-32/R-134a（30/70 wt％）, which might reach a low temperature —40℃. This system utilizes only one single compressor with a phase separator in order to shift the concentration contents of the refrigerant mixtures .The vapor phase flows through a cascade heat exchanger and exchanges latent heat with the low temperature liquid phase after expansion. Then, the mixture rich with higher boiling component flows into the evaporator to create the low temperature cooling, and merges with the mixture rich with lower boiling component, which leads finally back to the compressor and thus completes a cycle. This system have two advantages. First, utilization of the temperature glide of zeotropic refrigerant mixtures can reduce heat transfer irreversibility in the heat exchangers. Secondly, the phase separator shifts the concentration percentages of the components by the temperature difference of the boiling points. Thus, this system can raise the cooling capacity and can reduce the power consumption. Test results for a R-32/R-134a (30/70 wt %) cascade loop, compared with a baseline loop, indicates the increase of only 6％ in the power consumption and degradation of 10％ in the COP. In conclusion, this system can raise the evaporating pressure, can reduce the pressure ratio with one single compressor, and can achieve the designed low temperature.

Abstract:
The paper analyzes electric energy consumption of three different refrigeration installations: cascade refrigeration system with R134a in the high temperature circuit and CO2 in the low temperature circuit, single stage refrigeration system operating with R404A and two-stage transcritical CO2 system. The indirect impact of the refrigeration system on global warming through electric energy consumption was examined. Thermodynamic cycles of these installations have been described and models have been developed to analyze the electric energy consumption required to drive the compressor as the largest consumer, for the cooling capacity of the evaporator 5,7 kW at evaporation temperature -30 °C for meteorological 2017, in the city of Belgrade. As a basis for comparative analysis, the existing cascade refrigeration system, which is located in the Laboratory for Thermal Science at the Faculty of Mechanical Engineering in Belgrade, was selected.

Abstract:
Hydrocarbon based energy sources such as coal, oil and natural gas have been diminishing in an increasing speed. Instead of finding alternative energy sources, we have to use the available sources more effectively. By means of the irreversibility analysis, we can determine the factors or conditions that cause the inefficiencies in any energy system. In this study, irreversibility analysis of a compression cascade refrigeration cycle that consists of a high and low temperature cycles is presented. In the high temperature cycle, the refrigerants from different classes, namely R12 (CFC), R22 (HCFC), R134a (HFC) and R404a (Azeotropic) are selected as working fluids. In the low temperature cycle, R13 is only used as a working fluid. Irreversibility analysis of refrigerant pairs, namely R12-R13, R22-R13, R134a-R13, and R404a-R13 are carried out in a compression cascade refrigeration cycle by a computer code developed. The effects of evaporator temperature, condenser temperature, and the temperature difference between the saturation temperatures of the lower and higher temperature cycles in the heat exchanger (ΔT) and the polytropic efficiency on irreversibility of the system are investigated. The irreversibility of the cascade refrigeration cycle decreases as the evaporator temperature and polytropic efficiency increase for all of the refrigerant couples considered while the irreversibility increases with the increasing values of the condenser temperature and ΔT. In the whole ranges of evaporator temperature (−65°C / −45°C), condenser temperature (30–50°C), ΔT (2–16K) and polytropic efficiency (%50/%100), the refrigerant pair R12-R13 has the lowest values of irreversibilities while the pair R404a-R13 has the highest ones. At the lower condenser temperature (<30°C) and higher polytropic efficiencies (85%–95%), the refrigerant couples except for R404a-R13 have approximately the same values of irreversibility.
