title: Preliminary study on energy saving performance of a transcritical CO2 heat pump for food processing industry.

description: In food processing, there are significant simultaneous demands of cooling (range: 0°C-15°C), warm water (range: 25°C-70°C) and hot water (range: 75°C-100°C) for washing, blanching, pasteurization, CIP (Cleaning-in-Place), and other processes. Most of the heated water is used only once rather than recycled. The water to be heated usually comes from environment and its temperature will vary as ambient temperature changes. In order to reduce energy consumption and greenhouse gases emission, a transcritical CO2 heat pump system is proposed that can supply not only cooling, but also warm water and hot water simultaneously to meet the thermal demands of food processing. Simulation results showed that the potential primary energy saving rate of the proposed CO2 heat pump is from 50% to 60% when inlet water temperature ranges from 5°C to 30°C during a year.

title: Demonstration of free cooling with CO2.

description: The use of CO2 as a pumped secondary volatile heat transfer medium is demonstrated for a server room application. The condenser of the primary refrigerating system using propane comprises an additional air cooled heat exchanger for condensing CO2 when the ambient temperature is sufficiently low. This free cooling arrangement reduces the compressor operation time to less than 30% of the year in the Danish climate. The performance has been measured and recorded by utilising the building management system and the refrigeration plant controller, and it is evaluated against the design conditions. Characteristics of the control system are analysed, and observations during the first years of operation are reported. Measurements confirm that that the free cooling system alone will maintain the design cooling capacity of 100 kW supplying air at 25°C to the server room, when the ambient temperature is 13°C or lower. The design pressure is 70 bar for the CO2 cycle and evaporation temperatures close to 20°C have been recorded at part load conditions.

title: Experimental characteristics of R744 ejectors for expansion work recovery in heat pumping installations.

description: R744 ejector geometries were investigated experimentally at the multifunctional test facility designed specifically for ejector mapping. Based on the recorded primary and secondary mass flow rates, individual operation curves were determined for a typical range of operating conditions in refrigeration units for supermarkets. It was concluded that the two independent variables influencing the motive nozzle mass flow rate are inlet pressure and inlet temperature, i.e., the nozzle mass capacity was independent of the backpressure. Significant influence of pressure lift on the ejector efficiency was registered for each specified combination of inlet conditions. The maximum recorded efficiency values, equal to 0.368 for vapour compression, outperformed significantly the results reported so far in the literature. The approximation functions for both the primary mass flow rate and entrainment ratio were provided.

title: 3D and transient numerical modeling of door opening and closing processes and its influence on thermal performance of cold rooms.

description: The need of rationalize energy consumption in agrifood industry has fasten the development of methodologies to improve the thermal and energy performances of cold rooms. This paper presents a 3D transient Computational Fluid Dynamics (CFD) modelling of a cold room to evaluate the air infiltration rate through sliding doors. A species transport model is used for modelling the tracer concentration decay technique. Numerical predictions indicate that air temperature difference between spaces affects the air infiltration. For this case study, the infiltration rate increases 0.012 m3 s-1 per K of air temperature difference. The knowledge about the evolution of air infiltration during door opening/closing times allows to draw some conclusions about its influence on the air conditions inside the cold room, as well as to suggest best practices and simple technical improvements that can minimize air infiltration, and consequently improve thermal performance and energy consumption rationalization.

title: Optimizing combined cryogenic and conventional freezing with respect to mass loss and energy criteria.

description: The objectives of this work were to evaluate the advantages brought by using cryogenic freezing in comparison to blast air freezing with respect to weight losses and freezing times during food freezing. A mathematical model was then developed to predict the freezing time and the weight loss of food during freezing in very low ambient temperature. The model, first validated with experimental results, was then used to study the combination of cryogenic freezing and conventional freezing on different products such as meat and bread. The influence of the time spent in a cryogenic freezer to the freezing time, the mass loss and the energy consumption was especially evaluated. Results have shown that the behaviour of the product strongly depends on its thermophysical properties and its geometry/size and that there seems to be a linear relationship between the time spent in the cryogenic freezer, the freezing time and the energy consumptions.

title: Field measurements of ground source heat pump systems installed in existing single family houses - Evaluation after several years of operation.

description: Twenty Swedish ground source heat pump systems in single-family houses have been monitored during two years by SP on behalf of the Swedish Energy Agency. The houses were built between 1940 and 1979 and the heat pumps were installed during 2001 – 2007. The total heat supplied to space and domestic hot water heating differs considerably between households. The first year was colder than the second year which was shown to have an impact on the SPF, the Seasonal Performance Factor. The results from the two years of measurement showed SPF values between 1.9 and 3.5 (average 2.7) for the first year and for the second year, the SPF ranged from 2.1-3.6 (average 2.9). The energy coverage ratio ranged from 93% to 100% during the second year. There was no obvious sign of a deteriorated performance of the heat pump systems after several years of operation.

title: Numerical studies on passive vapor compression cycle regulating elements.

description: The present work analyses the role of both the capillary tube and the low pressure accumulator on domestic refrigerators. The main goal is to provide a better insight on how the refrigerant flow is regulated by the capillary tube and how the accumulator stores and releases refrigerant according to the system needs. To this end, an in-house numerical simulation tool is used to reproduce a comprehensive experimental study on household vapor compression refrigerating cycles found in the technical literature. The detailed numerical predictions are used to carefully examine the thermal and fluid-dynamic behavior of the two elements mentioned above together with their effect over the whole system. The results show good qualitative agreement with the experimental data and contribute to have a deeper understanding on the passive regulatory mechanisms acting on such systems.

title: Natural refrigerant mixture alternatives retrofit eco efficiency comparative study case.

description: This paper has focused on the natural alternatives: ammonia, CO2 and mixtures with zero and low global warming potential (GWP). The theoretical study analyzed one stage refrigeration system that currently works with R 404A. To implement the International Legislation, in the future it is necessary to retrofit HFC refrigerant with an ecological refrigerant R717 or R744. The comparative study of these facilities followed the coefficient of performance of a plant and also the TEWI factor (Total Equivalent Warming Impact – in respect with EN 378-1). Energy efficiency is directly related to global warming and greenhouse gases emissions.

title: Simulation of an absorption refrigerator working with ionic liquids and natural refrigerants.

description: Electrically-driven vapour compression or thermally-driven ammonia water absorption refrigeration systems are the commonly used technology for cooling below 0°C. Ionic liquids (IL) are versatile absorbents since they extend the use of natural refrigerants other than ammonia in thermally driven absorption technology. Moreover, room temperature ionic liquids (RTIL) do not crystallize at ambient temperature even up to high ionic liquid mass fractions just like water in ammonia water chillers. In addition, they exibit a nearly zero vapour pressure allowing for regeneration without rectification. The present study is concerned with the simulation of a single stage absorption refrigerator which has been designed specifically for the use of Ethanol as the refrigerant and an ionic liquid as the absorbent. The main feature of this study is the fact that no empirical heat and mass transfer coefficients have been used. Instead analytical functions for the combined heat and mass transfer using the molecular transport properties such as the mass diffusivity and heat conductivity for instance are used for the simulation. The vapor liquid phase equilibrium data as well as the transport and thermodynamic properties of Ethanol as refrigerant and [EMIM][DEP] as absorbent are presented in the paper at hand. The thermal efficiency and the refrigeration capacity of the absorption refrigeration system for varying driving temperatures are presented and discussed. As a special feature the behavior of this absorption refrigerator with two different heat rejection temperature levels is shown in order to determine its suitability for a double effect system.

title: Application investigation on a pumped loop heat pipe heat exchanger unit for a small data center.

description: The pumped loop heat pipe heat exchanger unit for cooling consumes low power and has a high coefficient of performance (EER). For optimization applications at small data centers, this paper investigated the operating performance of the pumped loop heat pipe heat exchanger unit used in a small data center. The EER under different outdoor temperatures was analyzed, and the fitted operating characteristic curve showed that EER varied with outdoor temperature. An energy saving analysis was done with the fitting curve, and the total energy consumption was calculated at each temperature interval in Beijing. The results show that in transitional and winter season, when the outdoor temperature is below 15°C, the pumped loop heat pipe heat exchanger unit can be turned on to bear part or total thermal load and performs well in energy saving. Compared to the air conditioning and refrigeration system for cooling, the energy saving can reach at least 35.76%.

title: Modelling of in-tube binary mixtures condensation in annular-mist flow with entrainment and deposition.

description: Mixtures condensation is widely encountered in liquefaction of natural gas process, refrigeration systems and other chemical and power generation industries. The study of the two-phase condensation region is of importance for the design of condensers, especially those employing multicomponent mixtures. This work presents a one-dimensional, three-field model to simulate the annular-mist flow regime considering a liquid film, droplets and a gas core. Considering the mass transfer resistance and the droplets interchange, the mass and species equations for each phase, the momentum and energy equations are solved for the in-tube condensation process of binary mixtures. The model is validated by experimental data from the literature. The flow characteristics, the compositions and temperatures in each field are analysed. The effect of the droplet interchange on the heat transfer is also investigated.

title: Freezing under electrical and magnetic disturbances; a review.

description: Phase change in biological tissues may be affected by electrical and magnetic disturbances. This presentation proposes a review based on existing literature as well as some very recent results on freezing under static electric field (SEF), magnetic field (MF) and microwave conditions. Freezing under static electric field of water, aqueous solution and pork meat has been investigated by the authors, showing the ability of this process to refine ice crystals in frozen matrices. SEF permits to lower the supercooling and to trigger the phase change of water to ice. The use of radiofrequencies and microwaves has been used recently by researchers to promote refined ice crystallization in food systems. Even though the energy optimization of the process is still in debate, the benefit in terms of size of ice crystals has been evidenced.
