title: Non-flammable, lower GWP alternatives to R-404A.

description: In an effort to comply with the worldwide regulations to reduce the environmental impact of refrigerants, there is large industrial movement to develop next generation refrigerants. In particular, alternatives to R-404A are gaining large interest, due to its wide usage in commercial refrigeration and relatively high GWP, among the HFCs currently in use. To this end, a lower GWP, non-flammable refrigerant ARM-32b has been developed as a replacement to R-404A. In this work, a drop-in test of ARM-32b was performed, and the capacity, performance, discharge temperature, and flow rate are presented along with the R-404A baseline. System results showed a potential for improved energy efficiency, while exhibiting similar capacity.

title: Geophysical survey of land off Foxlydiate Lane, Webheath, Redditch, Worcestershire (OASIS ID: wardella2-241312)

description: Between September 2015 and January 2016 Wardell Armstrong Archaeology (WAA) undertook a geophysical survey of land off Foxlydiate Lane, Webheath, Redditch, Worcestershire. The survey was undertaken for Hayford Developments Limited, to provide information to support a planning application for a mixed-use development at the site.  An historic environment assessment of the site has been undertaken by Wardell Armstrong, which will be presented in a separate report. The Worcestershire Historic Environment Record records the presence of Hawthorn Pit Quarry on the east side of the proposed development area, and several distinct areas of ridge and furrow cultivation. Possible settlement earthworks are also recorded on the west side of the site and a holloway is recorded east of Lanehouse Farm.   The objective of the geophysical survey was therefore to determine the presence/absence, nature and extent of potential archaeological features within the study area, and the presence/absence of any known modern features within the survey area, which may affect the results.   Geomagnetic survey was undertaken over the majority of the study area on a field by field basis, which comprised arable and pasture land at the time of the survey. A majority of the geophysical anomalies detected at the site are believed to be agricultural in origin, including further evidence for former ridge and furrow cultivation, and a number of former field boundaries and quarry pits/ponds, many of which are depicted on historic maps of the site. No other probable archaeological features were detected.

title: Raw data obtained to evaluate the effect of injection numerical aperture on the photonic lantern throughput

description: The transmission of light through the photonic lantern was investigated by injecting light of different numerical apertures (NAs). Light at 550nm was collimated and projected through an adjustable iris. The light was then focussed using a plano-convex lens (Thorlabs LA1951-A, f = 25.4mm) onto the multimode port of the lantern, which was attached to a 20 m length of multicore fibre. The NA of the injected light was controlled by adjusting the size of the iris. The total throughput, the magnitude of which includes contributions from the multicore fibre propagation loss, input coupling loss and Fresnel reflections at the input and output of the device, was calculated from the power before the photonic lantern (Power in) and the power after the multicore fibre (Power out). The average propagation loss in the fibre was evaluated to be approximately 0.1 dB / m, while the Fresnel reflection was 0.18 dB / facet. This file contains the raw data obtained during these measurements, in terms of both Power in and Power out, as a function of iris diameter.

title: Design sensitivity analysis of a direct evaporator for low-temperature waste heat recovery ORCs using various flow boiling heat transfer correlations.

description: The study evaluates 14 flow boiling heat transfer correlations in an annular-finned horizontal round tube direct evaporator design problem for a low-temperature waste heat recovery Organic Rankine cycle (ORC) case. The direct evaporation is realized through an industrial flue gas having a volumetric flow of 10000 Nm³/h, with inlet and outlet temperatures of 232°C, which is representative for typical waste heat recovery operations for annealing furnaces, drying, baking, exhaust gas internal combustion engine. An iterative evaporator design is performed, where each of the considered flow boiling correlations are separately used for finding the in-tube convective heat transfer coefficients. The error margins of the tube length, overall heat transfer coefficient, transferred heat, cost, fan power and pressure drops are assessed. The considered working fluid is R245fa and the deduced optimal evaporation temperature (OET) is 120°C. The corresponding total transferred heat in the evaporator is approximately 300 kW in all calculations.

title: Heat transfer at supercritical state for organic Rankine applications.

description: In the last years, a lot of attention has been paid for developing technologies for low grade heat recovery. This work focuses on the possibilities to increase the performance of the Organic Rankine Cycle, by utilizing low grade heat source within a temperature range of 90°C - 200°C. One way to improve the performance is a proper selection and design of the components. On the other hand, a way of enhancing the overall cycle efficiency is introduced with supercritical heat transfer in the heat exchanger. The advantage is a better thermal match between the heat source and the working fluid temperature profiles in the heat exchanger. Because, correlations available from literature were used for designing of this component safety factor was also implemented to reduce the uncertainty level. In this work, results from measurement campaigns for a heat exchanger obtained at supercritical state are presented. It can be concluded that improving the design of the heat exchanger leads to better cycle efficiency and reducing the cost of an ORC installation.

title: Effect of installation faults on the performance of a split air conditioner.

description: The study analyzed the effect of common installation faults on the cooling performance of a residential, split air conditioner installed in a single-family, slab-on-grade house. We considered five climatic regions in the United States from hot/humid to cold. Through seasonal simulations of the house/air conditioner system, the study found that duct leakage, refrigerant undercharge, undersized refrigerant expansion valve, low indoor airflow, and air conditioner oversizing with non-oversized ductwork have the most potential for causing significant performance degradation and increased seasonal energy consumption. Seasonal energy use can significantly increase even more when the homeowner lowers the thermostat setting to remove excessive indoor humidity caused by certain installation faults.

title: Test rig for experimental evaluation of spray evaporation heat transfer coefficients.

description: Heat transfer coefficient (HTC) knowledge is crucial to design heat exchangers which meet the heat loads required. HTCs of typical heat transfer processes have been widely studied and are well known and correlated, but the spray evaporation HTC database for refrigeration purposes is limited and values differ between works. In order to contribute to this database, we have redesigned a test rig previously used to obtain condensation and pool boiling HTCs and included a refrigerant distribution system with spray nozzles. We have defined a calculation method to determine the fraction of refrigerant flow rate reaching the studied tubes. The test rig has been successfully validated and an experimental methodology and data reduction process have been developed for the determination of spray evaporation HTCs from the experimental data. A set of tests has been carried out and the results obtained are shown and discussed.

title: An experimental investigation of the optimum geometry of two nozzle counter flow vortex tube.

description: An experimental study of two nozzle Ranque-Hilsch vortex tube are carried out with air as the working medium. Performance of the vortex tube is measured by varying the operating and geometric parameters such as L/D ratio, cold mass fraction, operating pressure and cold end orifice diameter and number of nozzles. Three Cold end orifices diameters 3 mm, 4 mm and 5 mm are tested with three L/D ratios vortex tubes 12.5, 13.5 and 17.5. Inlet pressure is varied from 2 bar to 8 bar with the increment of 1 bar. It was found that for 4 mm cold end orifices diameter brings maximum cold end temperature drop of 25°C. It is observed that cold end temperature drop in case of double nozzle is better than that of with single nozzle. Maximum temperature drop is obtained with cold mass fraction in the range of 0.45 to 0.55 for the cases, single nozzle and double nozzles. Vortex tube with L/D ratio 17.5 performs better than other two chosen L/D ratios.

title: A R-32 transcritical heat pump for high temperature industrial applications.

description: Previous exergy optimization studies have shown transcritical heat pumps (HPs) are especially adapted to recover low-grade heat for high temperature targets. A 30 kW transcritical HP using the R32 as working fluid has been developed in order to validate the high energy performance predicted by a thermodynamic model. In this paper, the performances of an optimized HP prototype targeting a drying plant where ambient air is already preheated from 20°C to 60°C is presented. The target temperature of the process is 120°C and the effluents are available at 50°C. The real COP observed of the HP is close to 3.7 with an exergy efficiency of 63%. De précédentes études d’optimisation exergétiques montrent que les pompes à chaleur (PAC) transcritiques sont particulièrement adaptées pour valoriser la chaleur à basse température et répondre à un besoin à haute température. Une PAC transcritique fonctionnant au R32 de 30 kW chaud a été conçue dans le but de valider sa haute performance énergétique. Les dimensions de la machine ont été calculés afin de répondre aux conditions opératoires typiques d’une usine de séchage où l’air ambiant est préchauffé à 60°C, la température cible à atteindre est 120°C et les effluents sont disponibles à 50°C. Le COP observé est proche de 3,7 et le rendement exergétique vaut 63 %.

title: Comparative analysis of the performance of an offset-strip fin heat exchanger as evaporator in a refrigeration system with R22 and R417A.

description: Offset Strip Fins are often employed to build plate and fins heat exchangers used as condensers and evaporators in refrigeration systems, but the information available regarding them is not too extensive. Therefore, an experimental analysis of a refrigeration system which uses this kind of heat exchanger as evaporator was performed by using R417A and R22 as refrigerants. The heat transfer rate and the overall heat transfer coefficient in the heat exchanger were evaluated as a function of working conditions of the refrigeration system. Moreover, the heat transfer coefficient in the refrigerant side was obtained from the experimental overall heat transfer coefficient and the convection heat transfer coefficient in the secondary fluid side, which was previously determined in a set of tests performed by pumping water through both heat exchanger sides and applying a modification of the original Wilson plot technique.

title: Ice slurry as secondary coolant in air coolers. Mathematical model and validation.

description: A model for quasi-steady-state simulation of finned tube air coolers with single-phase secondary coolants has been modified in order to permit the study of ice slurry as secondary coolant, which is being nowadays proposed for applications such as supermarkets, cold storages, or air conditioning. The modifications have been implemented in a computer program, which has been validated against experimental data obtained in our laboratory by pumping ice slurry from an ethylene glycol solution through a standard fancoil. Once it was validated, the mathematical model appears as a useful tool to analyse thermal and hydraulic behaviour of this kind of systems, which can help to improve the design of these systems and optimize the operation conditions. In the paper, the mathematical model is described, the validation process is explained in detail and finally, some preliminary results are also reported and commented.

title: Ejector refrigeration systems for waste heat recovery applications: effects of condensation on performance.

description: As worldwide electricity demand increases and stresses electricity grids to the point of collapse, energy-saving devices have assumed increasing importance. Waste heat recovery systems are currently being considered for applications in air conditioning and refrigeration, like the ejector-based chiller considered here. The key ejector component is a steady-state device with no moving parts, obviating the need for lubricating oils, maintenance, or expensive repairs. An ejector-based chiller is constructed and experiments are conducted to demonstrate cooling over a range of conditions with a miniaturized ejector. It has been hypothesized that the occurrence of condensation at some operational conditions can be used to passively enhance momentum transfer and reduce losses within the ejector. This study experimentally determines the effect of flow condensation on ejector performance and, with analytical treatments of the expected degree of condensation within the ejector itself, uses this information to provide guidance on achieving maximum ejector efficiency and system COP.

title: Survival of Saccharomyces cerevisiae in refrigerated fresh orange juice treated with cinnamon leaf essential oil and thermo-sonication.

description: The survival of Saccharomyces cerevisiae in refrigerated fresh orange juice processed by combined use of thermo-sonication and cinnamon leaf essential oil (CLEO) was evaluated. The concentration of CLEO accepted by consumers in orange juice was determined by sensory analysis as 20 ppm. The resistance of S. cerevisiae cells to the action of ultrasound (24 KHz; 33.31 W mL-1; 30 minutes) at 50°C in orange juice with CLEO was analyzed. The survival of S. cerevisiae in the fresh orange juice untreated (control) and treated with thermo-sonication, or thermo-sonication plus 20 ppm CLEO and kept under refrigeration (5°C) for 28 days was studied. The best result was obtained with thermo-sonication and 20 ppm CLEO treatment. This treatment produced a reduction from an initial population of 5.18 log of S. cerevisiae in fresh orange juice to 2.60 ± 0.26 log after 30 min of sonication at 50°C. The best result of inhibition obtained during refrigeration was achieved with orange juice treated with 30 min of sonication at 50°C and 20 ppm CLEO because the treated juice kept under refrigeration at 5°C for 28 days diminished the S. cerevisiae population 1.33 ± 0.17 log.

title: Condensation heat transfer characteristics of low-GWP refrigerants in horizontal smooth mini tube.

description: R1234ze, R290, R161 and R41, which regarded as refrigerants with low GWP (Global Warming Potential). Condensation of these working fluids in a horizontal smooth round tube with inner diameter of 2 mm was investigated experimentally and compared with that of R134a and R32. The condensation temperature was set as 35 °C and 40 °C. The mass flux was set from 100 kg·(m-2·s-1) to 500 kg·(m-2·s-1). HTCs (heat transfer coefficients) of R1234ze, R290, R161 and R41,are from 1-13 kW·(m-2·K-1). The condensation HTC goes up as the saturation temperature decreases and the mass flux goes up. Under the same working condition, the HTC of R161 is the highest and that of R1234ze is the lowest. The change of pressure along the tube is tested and the trend that the pressure-drop changes with the saturation temperature and the mass flux. The predicted values calculated by 7 models including Koyama model are compared with 725 experimental values. It shows that different models fit for different refrigerants, while the Koyama et al’s model is prevealing over other models.
