title: Experimental investigation on flow boiling pressure drop of R600a in multiport minichannel tube.

description: An experimental study on boiling of refrigerant R600a in a multiport flat aluminium tube with 7 parallel mini channels with rectangular section and hydraulic diameter of 1.47 mm is presented. The effect of heat flux and mass velocity on frictional pressure drop was investigated for a constant saturation temperature and pressure. The ranges of these parameters are 50 to 200 kg/m²s and 5 to 27 kW/m², respectively for the mass velocity and heat flux, and the saturation temperature of 20°C. It was possible to observe the significant influence of mass velocity in pressure drop. The effect of acceleration component is also analysed. The refrigerant flow pattern is a very important parameter which influences the pressure drop. The images of flow patterns for different conditions were registered and the flow patterns observed were mainly slug, intermittent and annular. Isolate bubble and plug patterns were observed in specific conditions, as high mass velocity and low heat flux, for low vapor quality.

title: Potential of integrating the air-bearing heat exchanger into a refrigerator condenser.

description: In this paper, an air-bearing heat exchanger was applied to the condenser in a residential refrigerator, and its performance was investigated compared with conventional condensing unit. The air-bearing heat exchanger which was developed at Sandia National Laboratories estimated to have an enhanced air-side convection heat transfer and potential to increase the condenser performance. In the study, a prototype air-bearing condenser was designed and fabricated. Experiments on energy consumption according to DOE standard were conducted. The experimental results showed that the performance of the air-bearing condenser can match that of the conventional condensing unit, while its volume can be 60% lower.

title: Modified atmosphere packaging to extend shelf life of ready to eat fresh cut tomatoes.

description: The quality of ready to eat fresh tomato packaged with different mixtures of gases in the headspace was evaluated during 12 days at 4°C. Samples of tomato slices were packaged in polypropylene trays with 5 different mixtures of gases for MAP in a pilot plant. Microbiological analyses were performed in agreement with specific standard methods for aerobic count, enterobacteria, moulds and yeasts. Sensory assessment of samples was performed after 6 and 10 days. The samples packaged with 90%N2- 5%CO2-5%O2 were preferred by the panelists after 10 days of storage. The microbial counts also upholds the sensory test results because samples under the best accepted MAP showed the lowest concentration of enterobacteriaceae, moulds and yeasts during the experiment. In conclusion, the fresh cut tomato ready-to-eat is better preserved if the process is performed under MAP. According with our findings the best mixture of gases to be used was 90%N2- 5%CO2-5%O2.

title: Investigation of the steady-state temperature field characteristics inside a thermal cycling test chamber of turbulent mixed convection.

description: The steady state temperature field in a thermal cycling test chamber, where both the forced convection and natural convection contribute to the flow and heat transfer, is investigated by combined numerical and experimental method. A simplified algorithm has been developed for the wall boundary condition to deal with the complex wall compositions and the k-ε model is used for turbulence, which is validated by performing full scale experiments in a real system. The results show the steady temperature increases from top to bottom at the vertical centerline of the chamber and increases from bottom to top near the walls, due to the buoyancy force induced secondary flow. For the existing thermal cycling test chamber, the effects of the inlet flow rate and inlet temperature on the average temperature and the temperature uniformity are examined in the range of parameters 2.2 × 103 ≤ Re ≤ 4.3 × 106, 2.3 × 1013 ≤ Gram ≤ 3.6 × 1014 and Pr = 0.71.

title: Experimental study on performance of economized vapor injection heat pump system using refrigerant R32.

description: The refrigerant R32 is considered as a potential alternative refrigerant of R410A because of its low GWP and the basic thermodynamic parameters. It can effectively improve the heating efficiency and reduce the discharge temperature of the compressor to use the economized vapor injection (EVI) refrigeration system. In this paper, the performance of the EVI heat pump system using refrigerant R32 is investigated experimentally under the conditions of the evaporating temperature ranged from -2°C to -15°C. The experimental results indicate that the injection ratio, heat capacity and power consumption of the EVI heat pump system increase with the injection pressure. The max injection ratio of the EVI heat pump system is about 33% under the evaporating temperature of -15°C. For the EVI heat pump system, the system COP achieves the maximum value as the evaporating temperature is about -6°C, and the optimum injection pressure ranges from 1.50MPa to 1.54MPa. The discharge temperature of the EVI heat pump system drops by 11°C under the evaporating temperature of -15°C. As the evaporating temperature is below -6°C, the COP of the EVI heat pump system is higher than that of the traditional single stage heat pump.

title: Performance indicators for energy efficient supermarket buildings.

description: Performance indicators are needed to transform available measurement data into knowledge on the energy efficiency of a supermarket building. Such indicators are e.g. the supermarket size, the opening hours, the outdoor climate and applied energy saving options. When the energy use is related in to the supermarket size, opening hours, and other performance indicators, it should be possible to appreciate the energy use of the supermarket: is it relatively high, normal, or relatively efficient. IEA HPC Annex 44 “performance indicators for energy efficient supermarket buildings” searches for performance indicators that will allow to evaluate energy efficiency of existing single supermarkets, supermarkets within one chain, supermarkets across different chains and even supermarkets in different regions or countries. Based on new data from the Netherlands, this paper investigates the relation between sales area, opening hours and yearly energy consumption, and discusses other aspects that are needed to understand observed data.

title: Effects of weak magnetic fields on frosting process on surface of copper tube.

description: In order to find out how frost grows on surface of copper tube under different magnetic field intensity, frosting process on surface of copper tube under a week static magnetic field was investigated. The magnetic field was generated by a pair of Helmholtz coils and evenly distributed. The coils were connected to an adjustable direct current electric source. Frost pictures were taken and analysed. Results showed magnetic fields had complex and changeable effect on frost height and frost crystal morphology during the whole frost process. Under different magnetic field intensity, thinner, denser and longer frost crystals formed promotes frost growth, while sturdier, sparser and shorter frost crystals restrained frost growth. Research results could provide a reference for controlling frost by applying magnetic fields.

title: Preparation and thermophysical properties of MWCNTS/Paraffin composite phase change material.

description: To improve thermal energy storage performance of paraffin, multi-walled carbon nanotubes (MWCNTs) /paraffin composite phase change materials were prepared by using paraffin wax(PW) as matrix and as MWCNTs additives. The effects of different dispersant types and concentration ratios on dispersion performance of MWCNTs in PW were studied, and the effects of respective concentration ratiosof dispersant and MWCNTs on thermal energy storage performance of MWCNTs/paraffin composite phase change materials were also studied. The results showed thatSDBS hadbetterdispersionperformancethan otherdispersants; when SDBSand MWCNTs mass ratio was 2:1, the best dispersion of MWCNTs was achieved; when the mass ratio of SDBS and MWCNTswas 2:1 andthe mass fraction of MWCNTs was 0.6wt%, compared with pure paraffin, the fluctuation of phase transition temperature was less than 3.0%, the phase change enthalpy was reduced about 4.8%, the thermal conductivity was 0.251W/(m﹒K), increased by 16.6%.

title: A measurement of velocity fields in a floor heating room for validation of CFD.

description: The data of the measurement result has been accumulated by using full-scale floor heating model aiming at the improvement of the predictive validation of CFD in the natural convection field. Data is not yet maintained for the wind velocity distribution though detailed temperature distribution was grasped by the study in the past. Then, a detailed measurement of the velocity of the wind in full-scale floor heating model was done in this study. The current of air properties in the model were grasped from the measurement result. Next, the CFD analysis that considered the measurement result was done for the model. When the measurement value was compared with an analytical value, the tendency to which both temperature distribution and the wind velocity distribution were roughly corresponding was seen.

title: Comparison between measurement and wind tunnel experiment intended for apartment house.

description: In this study, it is a purpose to clarify the effect of natural ventilation in apartment house. First of all, we measured the amount of ventilation in the existing apartment house. To confirm the influence on the amount of ventilation by level, we were measured in five levels. In addition, to examine the influence that opening space of the interior door gives to the amount of ventilation, interior door used the louver door. As a result of measurement, it was confirmed that the amount of ventilation is different depending on level and interior door opening space. In the second, to measure the wind pressure coefficient, we carried out wind tunnel experiment used the reproduction model. Results of comparison of measurement and the wind tunnel experiment, it found that the two tendencies are the same.

title: Parkes observations for project P282 semester 2008APRS

description: From 1989 to 2005, we have discovered a total of 23 millisecond pulsars in 47 Tucanae and obtained coherent timing solutions for 19 of those. This dataset has already allowed studies of stellar evolution and cluster dynamics and the first detection of the interstellar medium in a globular cluster. The remaining scientific objectives of this project can now be accomplished with less intensive, long-term timing: we want to keep track of the rotational phase of these pulsars and increase the number and precision of measured proper motions. The full analysis of all the previous data is still ongoing: we have recently found a new pulsar (47TucZ), confirmed and determined the orbit of a previously know object (47TucX), and determined the timing solutions of three others (the binary pulsar with the shortest orbital period, 47TucR, another eclipsing binary pulsar, 47TucW, and a newly dicovered binary, 47TucY). This has allowed the identification of these three pulsars in X-rays using Chandra and the identification of the companion of 47TucY in optical HST data.

title: Performance investigations on 10W/60 K high-capacity, light-weight single-stage pulse tube cryocoolers for space applications.

description: The paper presents performance investigations on high-capacity, light-weight 60 K single-stage SPTCs to provide appropriate low-vibration cooling for next-generation very-large-scale long wavelength infrared focus plane arrays. Both coaxial and in-line arrangements are tried to adapt to different payloads and interfaces. The application background and cooler designs are described in detail, and the performance characteristics of the two arrangements are presented and compared systematically. The relative Carnot efficiencies of 10.57% and 10.69% at 60 K have been achieved for coaxial and in-line arrangements, respectively, with the typical cooling capacity of 10 W achieved for each. Reject temperature adaptability from 290 K to 310 K, typically 10.5 W/10 K and 8.6 W/10 K, respectively, are satisfactory for both arrangements. Each arrangement has a light overall mass below 12 kg, and the largest temperature fluctuations at 60 K of both arrangements in 6 hours are below the required 0.1 K.

title: Use of zeotropic blends in flooded refrigeration loops: consequences and limits.

description: In response to phasing out of HCFCs and to phasing down of HFCs with high GWP, the chemistry industry proposes a large panel of low GWP blends of HFC or HFC-HFOs. These blends are tailored in order to ensure a best compromise between themophysical properties, technical properties and safety properties. This results in the proposition of a large list of blends, each of them having its own specific components and composition. One of the common characteristics of these tailored blends is their zeotropic behaviour. This particularity tends to prevent their utilization in industrial refrigeration where liquid vapour separators (MP, LP) are often used. But in regard to the number of candidates to replace pure HCFC (mainly R22) or high GWP HFC blends (mainly R507A and R404A), the problem of the use of zeotropic blends in these applications is to be addressed. In this context, the present paper proposes to study the behaviour of zeotropic blends in flooded refrigeration loops. This behaviour is assessed by using Refprop software V8. The difference between calculation made with taking into account the fractionation of the fluid and the calculation made without taking this fractionation into account will be highlighted. A single stage flooded system is investigated. The impact of the temperature glide on the performances of this system will be assessed with fluids proposed for R22 replacement (for instance RS 45). Fluids with higher glide will also be assessed (for instance, R407F) as well as the effect of the evaporating temperature on the phenomenon.

title: Novel reduced GWP refrigerant compositions for stationary air conditioning.

description: The current fluids most widely used for small and mid-sized air conditioning systems globally are R-410A and R-22. While these fluids have many positive attributes for cooling, they are the subject of valid criticisms regarding their high direct global warming potential (GWP) and, in the case of R-22, ozone depletion potential (ODP). In the interest of improved environmental sustainability, a new class of refrigerant molecule has been developed, the hydrofluoroolefin, or HFO. While the very low direct GWP values of these molecules are attractive, none of the HFOs by themselves are fully satisfactory for use in conventional R-22 or R-410A type stationary air conditioning system designs, with concerns about capacity and flammability. Blended HFO based refrigerant candidates have been developed to provide better overall safety and performance, while retaining significant environmental sustainability properties versus the legacy refrigerants. Although no single candidate has yet been developed that meets every proposed requirement for a refrigerant fluid, this paper discusses three candidate fluids that have been developed to most nearly meet the most often cited sets of environmental, physical and performance properties for air conditioning. The candidates include DR-5A (R-454B pending) a 2L flammable gas that gives capacity performance near that of R-410A, a nonflammable composition for use to replace R-22 in high ambient temperature environments, DR-93 and a 2L flammable replacement for R-22 with a direct GWP of less than 150, DR-3. The trade-offs that exist between volumetric capacity, efficiency (COP), temperature glide, GWP value, and flammability have been explored and assessed. We report on the performance of the new compositions in both thermodynamic refrigeration cycle models at standard AC and high ambient temperature operating conditions, and in actual operating systems. These new compositions should provide useful options to help maintain the quality of life and health benefits from air conditioning and refrigeration, but in an energy efficient and environmentally sustainable manner.

title: Development of the CO2 refrigerated showcase.

description: We developed a refrigerated showcase using CO2 as a refrigerant, instead of R404A.The high-efficiency inverter compressor used in the heat pump water heater “EcoCute” was applied for improving the system performance. Two cooling fans could supply the required air flow in a duct blocked by the compressor in order to improve the performance of the air curtain. In addition, reduction of pipe pitches and number of pipes at the windward of the evaporator were done to get uniform frost formation. As a result, the energy consumption decreases by 42% compared to the conventional system (R404A refrigerant, GWP=3940).

title: Numerical study on the leakage characteristics of a scroll compressor.

description: Scroll compressors have been used for various types of systems due to its advantages such as small size, simple structure, and high reliability. However, the refrigerant leakage in the scroll leads to a negative effect on the overall performance of a scroll compressor. In this study, a numerical simulation on a variable speed scroll compressor is carried out. The model contains heat/mass transfer and geometrical analysis for the characteristics of the refrigerant leakage. The model is validated by comparing the results with the experimental data for an R-410A heat pump. The mass flow rate and compressor power obtained from the simulation are within ± 6% and ± 4%, respectively, of the experimental data. The characteristics of the refrigerant leakage were analyzed theoretically and the variation of volumetric efficiency was also discussed in various operating conditions.

title: Comparison of heat exchange rates between straight and slinky horizontal ground heat exchanger.

description: Horizontal ground heat exchanger (HGHE) operation in ground source heat pump systems is prone to unstable thermal performance due to temporal weathers and seasonal variations. Therefore, the design of such installation is important to ensure the optimum efficiency during its operation. In this work, the numerical modelling of HGHE operation in different configurations was modelled to predict the outlet temperature and heat exchange rate. The effect of pipe materials of different thermal properties on heat exchange rate of HGHE operation was also studied. The analysis includes comparison of heat exchange rates between straight and slinky configuration. Although the heat exchange per pipe length for slinky configuration is lower, the heat exchange per trench length outperforms the straight configuration due to the greater surface area provided. Copper pipe shows a significant increase in thermal performance in HGHE operation attributed by superior thermal properties compared to the commonly used polyethylene pipe.

description: In the selection task, participants had to select the region of interest (a specified vessel segment) as explained in the "Experiment_description.pdf" file. They were asked to manipulate (i.e., translate, rotate and scale) a 3D box widget, initially positioned such that the region of interest covered all vessel structures displayed on the screen. Three 3D model files ("level1.vtk", "level2.vtk" and "level.3 vtk") were used to define three complexity levels of the selection task: Level 1 (simple) — one vessel; Level 2 (average) — two closely located vessels; Level 3 (complex) — three vessels, where two vessels are located close to each other. This project was funded by the University of Amsterdam and NWO.
