title: Numerical investigation of the transcritical CO2 heat pump system employing different expansion devices.

description: It is well known that the high irreversibility in the throttling process degrades the performance of the transcritical CO2 heat pump system that employs expansion valve. To tackle this problem, different expansion devices have been proposed and investigated including expansion turbines and two-phase ejectors. A numerical analysis has been conducted in this study to compare the performance of these expansion devices. A numerical model has been developed using MATLAB and the thermophysical properties are provided by a database REFPROP. The working parameters and correlations were taken from verified experimental and theoretical studies in literatures. In the present study, the results show that the two phase ejector has a better coefficient of performances (COP). The cycle with an ejector can achieve a COPh about 5% and 15 % higher than that of the cycles with a turbine and a valve as expansion device, respectively. The findings showed that the advantages of the ejector cycle include the reduction
of irreversibility and the energy recovery in the throttling process of the transcritical CO2 heat pump system.

title: Experimental measurements and computational predictions of the gas flow field in refrigerant oil separator.

description: Oil separators are essential components in a refrigeration system to ensure optimum performance of heat exchangers and overall plant efficiency. A key factor in being able to determine the performance of an oil separator is to understand the gas flow field within the unit which leads to droplet separation. This study utilises experimental data using Laser Doppler Anemometry (LDA) in a Perspex replica of a helical oil separator to validate a single phase computational model using Fluent 6.3.26. Four turbulence models were assessed against the experimental data which demonstrated that those based on the eddy-viscosity hypothesis fail to accurately predict the Precessing Vortex Core (PVC) which was visualised experimentally. The use of more complex turbulence approaches such as the Reynolds Stress Model (RSM) and Large Eddy Simulation (LES) produced results which were in reasonable agreement with the results obtained experimentally.

title: Performance of the refrigeration system with capillary injection in evaporator.

description: It is interesting to improve the performance efficiency of the refrigeration system by the utilization of the high pressure refrigerant. Based on the field synergy theory, a new type of refrigeration system was provided, in which the high pressure refrigerant was injected into the evaporator coil from the hole opened on the capillary inserted in the evaporator coil. The change law of the synergy angle between the flow and heat flow along the hole diameter and the capillary diameter was analyzed theoretically. And the visual experiments were carried out. The theoretical results show that the synergy angle is reduced with the decrease of the hole diameter and the capillary diameter, but the effect of capillary diameter is also reduced with the decreasing of the capillary diameter. The experimental results show that compared with the conventional refrigeration system, the refrigerant mass charge is reduced more than 70%, COP is improved by 9% and the time to reach the stable state is reduced by 70%.

title: Alternative alcohol blends as secondary fluids for ground source heat pumps.

description: The most common secondary fluid used for the borehole heat exchangers in Sweden is an aqueous solution of ethyl alcohol (EA) due to its relatively good thermophysical properties and low toxicity. Commercially available ethyl alcohol based fluids in Sweden contain up to 10 wt-% denaturing agents in form of propyl alcohol (PA) and n-butyl alcohol (BA). The aim of this paper was to investigate the performance of the existing ethyl alcohol blend containing two denaturing agents and alternative alcohol blends in terms of the pressure drop and heat transfer in the BHE and comparison with ethyl alcohol based secondary fluid. Experimental results showed that the presence of these denaturing agents improves thermophysical properties such as specific heat capacity, thermal conductivity and dynamic viscosity when added in small concentration. EA18 + PA1.6 +BA0.4 and EA18.4 + PA1.6 present the best characteristics in terms of the heat transfer and pressure drop. Both blends are giving higher heat transfer coefficient by 9.4 % (EA18 + PA1.6 + BA0.4) and 8.11 % (EA18.4 + PA1.6) than pure EA20. Both blends are giving as well lower pressure drop than EA20 by up to 2.7 % (EA18 + PA1.6 + BA0.4) and 3 % (EA18.4 + PA1.6). EA18 + PA1.6 + BA0.4 gives 1.4 % higher heat transfer coefficient and EA18.4 + PA1.6 gives lower pressure drop by up to 0.4 % when these two blends are compared.

title: Ethyl alcohol based secondary fluid: effect of corrosion inhibitors on thermophysical properties.

description: Currently available commercial ethyl alcohol (EA) based secondary fluids in Sweden and other Nordic countries contain up to 10 wt-% denaturing agents (in concentrate alcohol) in form of propyl alcohol and n-butyl alcohol but no corrosion inhibitors. These studies were initiated due to a growing need for providing any protection against corrosion and extending the lifetime of the system. A literature search has been made to find the compatible corrosion inhibitors that can effectively protect the system. Afterwards, measurements have been performed to investigate the effect of these corrosion inhibitors on the thermophysical properties of the base fluid. Results showed that the different corrosion inhibitors can affect the thermophysical properties even when added in small concentrations. The presences of corrosion inhibitor had a positive effect and decrease the freezing point. Additionally, the presence of corrosion inhibitor in 30 wt-% ethyl alcohol samples had no significant effect on the dynamic viscosity and only EA25 + 0.01 SG (sodium gluconate) sample showed lower dynamic viscosity value by up to 10 %. The corrosion inhibitors had negative effect on the thermal conductivity in the full temperature range. EA25 and EA30 samples containing sodium gluconate, benzotriazole and sodium molybdate had higher specific heat capacity than the pure solutions. This study showed that both benzotriazole and 2mercaptobenzothiazole seem to be the most promising corrosion inhibitor for ethyl alcohol based secondary fluids.

title: Experimental results of a high efficient booster prototype system for sanitary hot water production using propane as refrigerant.

description: CO2 heat pumps has been used for sanitary hot water production due to its good performance working with high water temperature glides. Traditionally, it has been considered that these kind of systems are able to work in these conditions with a higher efficiency because they can match refrigerant temperature profile in the gas cooler to the water temperature in a better way than subcritical systems. This paper presents the experimental results obtained from a new heat pump booster prototype for sanitary hot water production up to 60ºC using propane as refrigerant and working in subcritical conditions. The system configuration is able to overcome the high water temperature glide (10ºC to 60ºC) using a system configuration in which the condenser is able to work at high subcooling without increasing significantly the condensing temperature. The obtained results present a high COP (5.4 in nominal conditions) which is quite competitive with most of the systems available in the market for these application.

title: Air-driven cooling device for high tech electronics.

description: Our paper presents a cooling device that can produce a stream of cooling air at temperatures down to -50°C. Three different air-driven cooling device prototypes have been developed for cooling of siliconbased charged particle detectors and electronics. The devices are able to provide a range of cooling temperatures at moderate or low heat fluxes to be removed (up to hundreds of watts). Our new AIRCOOLERs use the principle of Vortex tube cooling. A wide range of temperatures down to -50°C is achieved with a nominal standard air pressure of 0.8 to 0.9 MPa which is in the range of the supply lines in the most laboratories and industrial facilities. Their simple box-like design, equipped with Vortex tubes and heat exchangers, has no moving parts and requires only a pressurized dry air supply to provide the cooling effect. It is ideally suited for applications in laboratories and also for applications with a problematic ambient environment, such as strong magnetic fields or high radiation levels.

title: Spray Drift data from Flat fan and air Induction nozzles in IRSTEA Wind tunnel

description: These data correspond to sedimented deposition in IRSTEA wind tunnel for different types of nozzles (Flat Fan Albuz AXI and Air induction Albuz CVI 02 - 2.5 bar) at different heights (40 - 60 - 80 cm) and different wind speeds (2-4-7.5 m/s) Wind tunnel has a cross section of 2 x 3 x 9m (h x w x l) and sedimented droplets are collected on a distribution test bench (acc. ISO 5682) with grooves of 5cm width, 10 cm depth and 3m length. Deposition is weighted after a certain volume (Max capacity of filling tubes 500ml) or a certain time (ex 30 min). Each column gives the deposition value (expressed in relative flowrate) according to the settings inidicated on the first rows. The last row corresponds to the addition of deposition and provides the recovery rate on the distribution test bench. Sprayed liquid is water. 4 nozzles spaced 50 cm are set on a boom at the defined height and pressure. Input flowrate and pressure are controlled along the experiment. Wind speed is controlled with a 2D US anemometer, air temperature and humidity are controlled with ad hoc sensors and with the help of heating/cooling system.

title: Evaluation of natural working fluids for the development of high temperature heat pumps.

description: For a sustainable future in energy, the use of natural fluids in heat pump systems can provide an efficient solution to combat the ozone depletion and the global warming effects of synthetic working fluids. These natural fluids, though environmentally friendly, must be able to operate at high temperature in heat pumps in an efficient and cost effective way to be viable for the industry heat demand. High temperature heat pumps with heat source and heat sink temperatures ranging from 40 oC to 200 oC have unique challenges with natural working fluids. This paper evaluates the performance and use of natural working fluids for high temperature heat pumps. The analysis is based on simple thermodynamic cycles. A simulation tool coupled with a thermodynamic properties database is used to evaluate the operating limitations of the natural fluids. Natural fluids such as ammonia, hydrocarbon and hydrocarbon mixtures are considered. The hydrocarbon mixtures, benefitting from both adjusted thermodynamic properties and a higher evaporating temperature due to better fit to heat source temperature, shows greatest potential for the development of high temperature heat pumps. The mixtures R290+R600 and R600+R601 were able to expand the working limits of their pure fluids while improving COP by up to 13.5 %.

title: Project NxtHPG: next generation of heat pumps working with natural fluids. First assessment of the project results.

description: NxtHPG project ‘Next Generation of Heat Pumps working with natural fluids’ is a Research and Development project partially funded by the European Union under the frame of the Seventh Programme for research, technological development and demonstration of EU, under grant agreement No [307169]. NxtHPG project targets the development of a new series of safe, reliable, high efficiency heat pumps working with natural refrigerants (namely: Hydrocarbons and CO2) up to 60 kW of heating capacity, in several applications where the take-off of this technology could be reasonably short if the performance of the unit is good and the cost is reasonable. The project involves a large group of OEMs of both components and heat pumps who are providing their best technology to reach the project objectives. The objectives, structure and first results of the project were previously presented at Gustav Lorentzen 2014. During the first year of the project, five heat pump prototypes were designed, modelled and constructed: 3 prototypes working with propane and 2 prototypes working with CO2. After the construction of the prototypes, a first experimental campaign was carried out by the research groups involved at the different labs located in Stockholm, Spain and Italy. This paper presents an initial assessment of results of the project with a critical review of the objectives.

title: HESML V1R2 Java software library of ontology-based semantic similarity measures and information content models

description: HESML V1R2 is the second release of the Half-Edge Semantic Measures Library (HESML) [1], which is a new, scalable and efficient Java software library of ontology-based semantic similarity measures and Information Content (IC) models based on WordNet. HESML V1R2 implements most ontology-based semantic similarity measures and Information Content (IC) models based on WordNet reported in the literature. In addition, it provides a XML-based input file format in order to specify the execution of reproducible experiments on WordNet-based similarity, even with no software coding. The V1R2 release significantly improves the performance of HESML V1R1. HESML is introduced and detailed in a companion reproducibility paper [1] of the methods and experiments introduced in [2,3,4]. The main features of HEMSL are as follows: (1) it is based on an efficient and linearly scalable representation for taxonomies called PosetHERep introduced in [1], (2) its performance exhibits a linear scalability as regards the size of the taxonomy, and (3) it does not use any caching strategy of vertex sets. HESML V1R2 is freely distributed for any non-commercial purpose under a CC By-NC-SA-4.0 license, subject to the citing of the main HESML paper [1] as attribution requirement. On other hand, the commercial use of the similarity measures introduced in [2], as well as part of the intrinsic IC models introduced in [3] and [4], is protected by a patent application [5]. In addition, any user of HESML must fulfill other licensing terms described in [1] related to other resources distributed with the library, such as WordNet and a dataset of corpus-based IC models, among others.

title: Performance evaluation of a large capacity air-water heat pump using propane as refrigerant.

description: Heat pump applications working with hydrocarbons as refrigerant have been under significant development along with the gradual phasing-out of conventional HFC systems. In this study, a large capacity air-water heat pump prototype using propane as refrigerant is tested to evaluate its heating performance under different operating conditions. The experimental set-up is briefly explained. The results of the experimental investigations of the heat pump prototype are presented in terms of the COP1, heating capacity and the compressor efficiency. At the design point, the experimental COP1 and heating capacity are 3.43 and 36.59 kW respectively. Experimental results for all test conditions are compared to simulation results generated from the model, which is created by the software IMST-ART. The model is validated through comparisons of those parameters since a good agreement between simulated and experimental data have been found. The maximum discrepancies of COP1 and heating capacity are around 5% and 10% respectively.

title: Supermarket application. Effects of sub-cooling on real R744 based transcritical plants in warm and hot climate. Data analysis.

description: Several techniques are under development worldwide to expand the convenient use of Carbon Dioxide (R744) in region with high external temperature. This paper analyses the effect of a sub-cooling device in real R744 trans-critical plants for supermarket application. A sub-cooling device is a system able to assist a gas cooler to cool a stream of trans-critical R744 before its expansion in the high pressure valve. The aim of the study is to understand how much the presence of a sub-cooler device helps the efficient use of R744 for refrigeration in commercial application in the hot and warm temperature region. The use of the sub-cooler reduces the discharging temperature and pressure peaks, as well as the power peaks and the overall energy consumption. This paper analyses a collection of data coming from different stores equipped with sub-cooling in order to compare them with stores without the sub-cooling device. Stores with different sub-cooling techniques have been analyzed such as mechanical, groundwater and integration with A/C.

title: Influence of refrigerant choice on performance of air-source heat pumps.

description: Air is the cheapest and most readily available source of heat for heat pumps. This paper shows that air is often neglected as a heat source because of perceptions that air-source heat pumps are less efficient than other types of heat pumps. Calculations are presented to show that in an appropriate location with an appropriate refrigerant, the air-source heat pump can produce SEERs in excess of three. Refrigerants considered include ammonia (R717), Isobutane (R600a), R134a and R410A. It is shown that the most appropriate locations for air-source heat pumps are temperate places at high latitudes where the heating season is long and air temperatures rarely fall below 0°C. The United Kingdom is such a location. A design of air source heat pump capable of operating at very low temperature differences in the evaporator is described.
