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.

Refrigeration system has a long history, and vacuum freeze-drying is a technology used for drying, color protection, fresh keeping, or nutrition preservation of food, biologics, biomaterials, or micro/nano materials, So Freeze-drying systems to be used for some time. But most operating temperature to the systems are -50℃, besides, old machines have only one cold trap chamber, if we want to remove the ice on cold trap, we will shutdown the machines, then Production process will be delayed. This thesis is focused on improving the cascade vacuum Freeze-drying Development, and this operating temperature can reach to -80℃,it is more favorable for specific high-tech products process and will not have a negative impact on production time. In experiments, freeze-drying system had a best evaporative temperature.

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. Further to research and analysis the relation of COP and mass flow ratio versus operating and design parameters of 6 group’s refrigerant in order to get optimization of parameter and analysed refrigerant in cascade low-temperature refrigeration system.

The cascade refrigeration systems are widely applied in Taiwan, for use in air conditioning, refrigeration and food processing, pharmaceuticals, chemicals, machinery, etc. More attention recently, So this thesis refrigeration components easily available in the market to buy the dual refrigeration system developed for conducted to explore various expansion valve of the refrigerant flow. The system of high and low temperature circulation system individually in four A, B, C and D expansion valve testing, in order to best binary refrigerating system expansion valve and the coefficient of performance. Results in a high temperature due to the circulatory system A, B, C the expansion valve of the refrigerant flow rate is too small, resulting in low temperature startup cycle, temperature cycle system can,t be stabilized at the intercooler below -30 ℃, the system also due to temperature cycling and A the flow of refrigerant expansion valve B is too small, the evaporator can,t reach -80 ℃, and start C expansion valve of the evaporator inlet temperature difference is too large, said it could not achieve a good cooling effect, this thesis high binary refrigeration system, hypothermic circulatory system are available starting D expansion valve coefficient of 0.45 for the best performance.

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.
