title: Cascade cycle high-temperature heat pump: modelling and validation.

description: The paper is devoted to the modelling and validation of a cascade cycle high-temperature heat pump installed in a single-family dwelling in Belgium. The heat pump can operate in three different modes: bottom cycle only, bottom cycle in parallel with cascade cycle and cascade cycle only, depending on the outdoor air temperature. The heat pump is equipped with detailed monitoring sensors in order to measure the real performance of the system. A stationary model of each heat pump mode has been developed in the Matlab ® environment. The field measurements are used to derive values for the parameters of each model. Firstly, we present the model of the heat pump. Secondly, we compare the results of the model with the measurements, which exhibits fair agreement. Thirdly, we present the results of the model, used to estimate the performance of the heat pump in function of the outdoor air and outlet water temperatures.

title: Flow boiling heat transfer of R1234yf on a microparticle coated copper surface.

description: This paper presents some preliminary experimental measurements collected during flow boiling heat transfer of low-GWP refrigerant R1234yf on a microparticle coated surface obtained via cold spray, a simple and non-expensive technique. The specific surface engineering was obtained by depositing a 100 µm thick pure copper coating on a smooth copper plate 200 mm long and 10 mm wide. The coating was deposited via High Pressure Cold Spray (HPCS) starting from a feedstock of pure copper particles with average size of 20 μm. The experimental measurements, carried out at the department of Industrial Engineering of the University of Padova, refer to a heat flux equal to 50 kW m-2, at a constant saturation temperature of 30°C; the refrigerant mass velocity was varied between 30 and 200 kg m-2 s-1, while the vapour quality varied from 0.2 to 0.95.

title: Ice slurry production system with absorption type vacuum freezing principle.

description: Unique ice slurry production method, which uses absorption type vacuum freezing principle, was proposed. In this study, we constructed the prototype apparatus and realize ice slurry production. In the evaporator of the apparatus, ethanol solution was placed as a refrigerant. Keeping the pressure in the evaporator low, ice slurry was formed in the ethanol solution, since the solution was cooled by the vacuum evaporation. Using this method, continuous ice slurry production can be realized. Since ice forms on the vapor-liquid interface in this method, ice adhesion on the cooling solid surface can be prevented, which inhibits the continuous production. Additionally, we installed the ice storage tank on the apparatus to avoid accumulation of ice in the evaporator, because it is important for the stable operation to keep the IPF (Ice packing factor) of ice slurry in the evaporator adequate level.

title: Performance modeling and monitoring of a high-temperature air-to-water heat pump with three different heating systems.

description: This paper deals with the performance monitoring and modelling of a capacity-controlled high-temperature air-to-water heat pump with injection cycle installed in a low-insulated house in Belgium. It is used for space heating and domestic hot water production. The monitoring consists of measuring in detail the performance of the system. The interest is in the fact that the heating system has been changed twice since the beginning of the monitoring so that we have results with radiators, convector heaters and a heating floor. Besides, a model of the heat pump and each heating system has been developed in the TRNSYS environment. The heat pump is defined statically by a table with manufacturer data values while dynamic thermal models of the house and of the heating system are used. Firstly, we present the monitoring results of the heat pump in space heating mode and in domestic hot water production mode. Secondly, we present the results of the model with each of the three heating systems. Finally, we compare the measurements with the results coming from the model.

title: Lithium bromide/R718 hybrid sorption & compression cycle.

description: The authors present a hybrid chiller concept with 20 kW chilled water capacity at temperature level of 10°C for very low driving heat temperatures below 65°C under European climate. The development comprises a thermally driven absorption chiller with working pair water/aqueous lithium bromide solution, including an electrically operated ultra-high speed turbo compressor at up to 90 000 rpm as capacity booster and backup. This concept is developed in order to broaden the operational capability of sorption chillers and heat pumps in combination with low exergy heat sources e.g. district heating, CHP-units and industrial waste heat. Starting from a description of the state of the art, the general system concepts and results of a steady-state thermodynamic simulation of the sorption & compression process in different configurations are described.

title: Evaluation of cycle performance of R448A and R449A as R404A replacements in supermarket refrigeration systems.

description: According to the requirements of the European regulation on fluorinated greenhouse gases, refrigeration equipment that contain high Global Warming Potential (GWP) refrigerants that have GWP equal or greater than 2500, with some exceptions, will be prohibited from placing on the European market from 1st January 2020. Moreover, the use of such fluorinated greenhouse gases to service or maintain refrigeration equipment with a charge size of 40 ton of CO2 equivalent or more will be prohibited as well. The greatest impact of the Regulation in the nearest time will be therefore on users of R404A refrigerant, which is the most popular refrigerant for supermarket refrigeration systems. Equipment users and manufacturers are therefore looking for the alternative refrigerants to replace R404A in new and existing equipment. R448A and R449A are potential R404A replacements. Both are non-toxic and non-flammable refrigerant blends that closely match the properties of R404A and have GWPs significantly lower than R404A. Cycle performance of a supermarket refrigeration system, operated with R448A, R449A and R404A is modelled in this study.

title: Ethyl and isopropyl alcohol blends as alternative secondary fluids.

description: Methyl and ethyl alcohol based secondary fluids are commonly used in different indirect refrigeration systems due to relatively good thermophysical properties. Methyl alcohol is considered toxic and not permitted for use as secondary fluid in most of Europe. Ethyl alcohol based secondary fluids are commonly used in Sweden due to their low toxicity and good properties. Commercially available ethyl alcohol based fluids contain up to 10 wt-% denaturing agents in form of propyl alcohol (2-propanol, isopropanol) and n-butyl alcohol (n-butanol). Results show that presence of propyl alcohol in the ethyl alcohol based secondary fluid improves its thermophysical properties such as specific heat capacity, thermal conductivity and dynamic viscosity when added in small concentration. The aim of this paper is to investigate the thermophysical properties of various ethyl and isopropyl alcohol blends in order to find the most optimal blend as well as to evaluate if this blend could become a competitive alternative secondary fluid.

title: Integration of a latent heat storage in VRF systems for heating and cooling with enhanced flexibility and efficiency.

description: In commercial and large office buildings, depending on external loads and different internal loads, heating and cooling phases may occur alternately in the course of the day or even simultaneously. In particular at the occurrence of simultaneous heating and cooling demand VRF (Variable refrigerant flow) systems are favorable compared to separate systems for cooling and heating. However, usually there is only a small overlap of heating and cooling periods. To further increase the heat recovery potential a thermal storage is required. With regard to the characteristics of compression heat pumps, a latent storage avoids the unfavorable temperature rise. For the integration of a latent heat storage in a refrigerant cycle of a VRF system, there are several possible configurations, aiming at different functions and different temperature levels of heat utilization. By using a dynamic model of the VRF system, the energy savings potential and target values for dimensioning and design of the latent heat storage are derived.

title: The role of heat pumps in the smart energy systems.

description: Heat pumps are needed in the future energy system to save primary energy, increase the share of renewable energy and thus to reduce climate impact. This is manifested in most recent future scenarios for low carbon energy systems that acknowledge the importance of efficient and reliable heat pump system. The role of heat pumps will change and broaden as the energy system becomes smarter. Information and smart controls in heat pumps coupled to storage possibilities will stabilize the electric energy system when the amount of flowing energy sources such as wind and solar energy increases. A stronger focus on resource efficiency and reduction of primary energy will put pressure on required seasonal performance factors for heat pump system. Increased system efficiency and high energy coverage are thus important challenges for heat pump system design. Hybrid systems where heat pumps are coupled to solar thermal energy and solar PV systems are likely to emerge on the market.

title: Thermal comfort and productivity for the future HVAC.

description: Office environment is important for office workers because it effects their satisfaction and also productivity. Recently, workers’ satisfaction is a focus of attention for office environment easy assessment. On the other hand, the International Energy Agency published latest World Energy Outlook 2013. The global demand for energy will keep rising. Jumping by one-third by 2035. Especially Asia region. Non-OECD Asian countries have more impact on economy and energy until 2035. Low-carbon energy sources will be able to meet around 40 percent of that growth. In Japan the Great East Japan Earthquake on March 11, 2011 caused enormous damage to infrastructure and lead to a 15% peak-power reduction in and around Tokyo. The purpose of HVAC is to maintain high indoor environmental quality (IEQ) and workers’ productivity. We conducted continuous field and questionnaire surveys in power-saving office buildings in the summers of 2011–2013. The results indicate that the thermal environment and indoor air quality recovered to pre-quake levels after 2012; whereas, considering the lighting environment, desk level illuminance was greatly decreased from 750 lux (pre-quake) to around 500 lux (post-quake). Nearly all of the workers are satisfied with IEQ today, but this differed with the workers’ gender, age, awareness of saving electricity, and work satisfaction. In particular, differences in workers’ awareness had a profound effect on their satisfaction with IEQ. This indicates that workers who were supportive of saving electricity experienced and reported greater satisfaction with IEQ. This conclusion will provide clue to the way of the operation and environmental control in the offices in Japan, also in the many countries which unexperienced such the great earthquake. Based on reported data future HVAC is described.

title: Flow boiling of R32 inside a brazed plate heat exchanger.

description: This paper presents recent measurements of heat transfer coefficient obtained during flow boiling of R32 inside a brazed plate heat exchanger (BPHE). Although R32 is known as a very interesting refrigerant for its thermodynamic and thermophysical properties, to the best of the authors’ knowledge, no flow boiling data are published in the open literature for this refrigerant working in brazed plate heat exchangers. The present experimental data are measured at the Department of Industrial Engineering at University of Padova. The experimental data are measured in order to investigate the effect of refrigerant heat flux, mass velocity, inlet vapor quality and superheating at the outlet. The saturation temperature is kept constant at around 5°C, which can be considered an interesting temperature level for evaporating temperature in liquid coolers. In the present paper data are also analyzed to assess available correlations for flow boiling inside BPHEs, in order to provide some guidelines on the predicting methods that should be used for evaporators using R32.

title: Heat and mass transfer to air in a cross flow heat exchanger with surface deluge cooling.

description: Cross flow heat exchangers, when applied to cool data center rooms, use external air (process air) to cool the air stream coming from the data center room (primary air). However, an air-air heat exchanger is not enough to cope with extreme high heat loads in critical conditions (high external temperature). Therefore, water can be sprayed in the process air to increase the heat dissipation capability (wet mode). Water evaporates, and the heat flow rate is transferred to the process air as sensible and latent heat. This paper proposes an analytical approach to predict the behavior of a cross flow heat exchanger in wet mode. The theoretical results are then compared to experimental tests carried out on a real machine in wet mode conditions. Comparisons are given in terms of calculated versus experimental heat flow rate and evaporated water mass flow rate, showing a good match between theoretical and experimental values.

title: A study of ice-slurry production process in scraped-surface type generator.

description: Despite of the widespread use of scraped-surface ice-slurry generators, there is no clear understanding of the processes occurring in them. There are not enough publications to create a reliable and universal methodology of designing such apparatus. At the same time, there is a problem of improving of the efficiency of the generator in order to increase its competitiveness. In this article, we analyses the model of formation of ice-slurry in scraped-surface generators, based on experimental studies of heat transfer processes in the generator, and formulate design methodology of generators which based on research work. Design solutions for the enhancement of heat transfer in the generator were developed and their influence on the efficiency of the ice-slurry production were studied.
