    The sensible heat accumulation is an efficient and low-cost way of storing thermal energy for its direct or indirect reutilization in typical building processes as space heating and sanitary hot water generation. The authors are developing both numerical and experimental tools for the study and optimisation of this kind of systems, focusing on the analysis of a specific sensible heat accumulator based on a cylindrical tank with an internal coiled pipe. The numerical simulation has been performed using a high-level platform that links two codes to solve the system. The fluid inside the tank is solved with a CFD&HT (Computational Fluid Dynamics & Heat Transfer) software called TermoFluids and the fluid flow inside the pipe is solved considering a quasi-homogenous fully-implicit one-dimensional model, where the governing equations are discretized along the whole tube domain. The resolution of the pipe wall in a detailed way couples both fluid solvers. On the other hand, an experimental infrastructure has been developed for the analysis of the system, which has been instrumented to provide detailed information of its heat storage capacity and temperature map. Several temperature sensors are incorporated in the heat accumulator at different heights and radius inside the tank. For the internal flow, the mass flow rate is measured, as well as the inlet and outlet temperatures. Different internal flow rates and operational temperatures have been studied both numerically and experimentally. From the results obtained it can be said that the device shows interesting heat storage capacities, while the numerical platform shows promising comparison results against the experiments.

    The aim of the paper is to gain a better insight into heat and moisture transfer in refrigerator and to do fundamental study for water evaporation and condensation in refrigeration application. The governing transport equations (continuity, momentum, energy and concentration equations) in 3D Cartesian coordinates are firstly introduced. As the mixed convection is simulated in the paper, buoyancy forces caused by both temperature and concentration gradient are considered and are also included in momentum equation. Numerical results are carried out by using Termofluids code. The pressure-velocity linkage is solved by means of an explicit finite volume fractional step procedure. In order to validate the code, a humid air flowing in a horizontal 3D rectangular duct case is carried out and compared with the published numerical and experimental results. The contour of temperature and vapor density of air at a cross section is provided and analyzed. Finally, the heat and mass transfer process during the moist air flow through complicated geometry is simulated and temperature and humidity distributions are obtained.

    The objective of this work is to simulate vapour compression refrigeration systems through a modular approach by means of an object - oriented numerical tool called NEST. For this purpose, the global system is modeled as a collection of different elements which are linked between them. Each element represents a specific part of the system (e.g. heat exchanger, compressor, expansion device, tube, cavity, wall, etc.) and can be independently solved for given boundary conditions. The global resolution procedure is carried out by solving all the elements iteratively, transferring information between them, until a converged solution is reached. The system is easily modified by adding, subtracting or substituting any of its elements. This feature gives great flexibility to the model, not only because the configuration of the system can be clearly altered, but also because the numerical model of any element can be easily replaced allowing different levels of simulation. In this work the object - oriented methodology together with the elements description and their resolution procedures are presented. The model is validated against experimental data obtained from a refrigeration cycle working with isobutane. In addition to this, an illustrative case is presented in order to show the system capabilities.

    The aim of this work is to study the thermal behavior and fluid-dynamic systems, vapor compression refrigeration and its components (heat exchangers, expansion devices, compressors, connecting pipes, pumps and pressure vessels). Topics discussed throughout this thesis arise from the growing interest in refrigerants friendly environment as well as different types of cooling systems for vapor compression has motivated the research group of the CTTC (Centre for Heat Transfer Technology ) to carry out major research efforts as well as participate in several projects with national and European institutions. The information contained in this thesis represents a summary of work performed by the author in recent years but also includes many of the contributions made by other members of CTTC. This thesis has led to the publication of several articles in international conferences. The main achievement of this thesis was the development of a numerical tool based on several subroutines flexibility to study different cooling Systemas vapor compression. The entire digital infrastructure has been the result of attaching specific numerical resolutions of each element of the cycle with the overall resolution algorithm. The simulations have been oriented to the study of thermodynamic cycle as well as to study some relevant aspects of the elements. In addition to the numerical results has been carried out important experimental work in the CTTC facilities in order to validate numerical models. The author has been fully involved in the process of data acquisition and has collaborated in the development of the units. The thesis is structured into five chapters plus a final conclusions and future actions. The first chapter, the introduction puts the reader in regard to the problematic situation, the history of cooling and objectives. The second presents the mathematical formulation and numerical methodology used in the simulation of the different elements and all cooling systems. The third study presents the numerical code verification. The fourth focuses on the validation of models with experimental results. And finally the fifth presents a suite of parametric studies and analysis. The numerical simulation code implemented has proven to be a flexible tool as various aspects of the steam compression systems have been successfully simulated and studied. It has also proven a reliable and good level of accuracy as the numerical results have been simulated properly the various experimental data compared.

    The air-to-refrigerant evaporator placed in no-frost refrigerators is a critical component because of its simultaneous treatment of both cooler and freezer air streams, which implies a strong drying process on the cooler air flow, and the corresponding intense and non-uniform frost formation process. This paper presents a numerical model developed to analyse fin-and-tube heat exchangers in general and this kind of evaporators in particular. This is a distributed model which gives a very detailed picture of the nonuniform heat exchanger behaviour in terms of heat and mass transfer, considering local effects (frost formation, fin density, in-flow state, etc.). The mathematical formulation and the numerical methodology are presented, showing the model capabilities and level of analysis. Afterwards, illustrative computational results show the potential of the model as a design tool for this application. Validation studies are included in an accompanying paper.

    The aim of this paper is to show the authors proposal for steady state numerical simulation of Vapour-Compression Refrigerating Systems (dry expansion, liquid overfeed systems, ...). The developed tool allows using different levels of simulation for some elements (compressors, pipes, etc.) as well as the possibility of use different kind of expansion devices. A verification study for a steady state regime is presented analysing also influence of mesh density and of the numerical accuracy. A validation study for steady state regime is shown. Some computational results for steady state regime are also presented to provide an overview of the level of detail given by the model. A set of parametric studies is finally given to evaluate the influence of some boundary conditions (environmental temperature, secondary inlet temperatures, etc.).

    The aim of this work is to introduce a numerical approach to study the transient response of vapour compression refrigerating systems. The emphasis is put on small capacity systems working with R600a (power consumption lower than 1 kW). The proposed method consists in linking all the specific sub-models of the cycle main components (compressor, heat exchangers and expansion device) and transferring adequate information from one to each other until convergence is reached. The model allows to simulate both steadystate and transient conditions. In order to validate the numerical scheme, an experimental facility (specially designed to analyze domestic refrigerators) has been built and used to collect relevant measurements. The work is focused on a specific case considering domestic refrigerating conditions at both steady-state and transient conditions. The numerical steady-state conditions are compared against experimental data, while a detailed transient process is numerically studied.

    This article is devoted to the study of air curtains applied to reduce the refrigerated chambers heat gains. The proposed strategy is based on the numerical simulation of air curtains by means of computational fluid dynamics (CFD) using RANS modeling and their corresponding experimental validation. Further work on the reduction of the detailed numerical results into overall energetic parameters is also presented. Unsteady three-dimensional numerical parametric studies are carried out, simulating the process of refrigerated chamber sudden door opening. The numerical solutions are verified and the influence of the turbulence model used is also investigated. The studies are centered on the influence of air curtain location, the air suction combination, and both the air discharge velocity and the discharge angle.

    Small capacity, air-cooled NH3–H2O absorption systems are becoming more attractive in applications where the input energy can be obtained for free (e.g., solar energy, exhaust gases of engines, etc.), due to the increasing price of the primary energy. One of the main difficulties for a wider use of absorption machines is the necessary high initial investment. For this reason, the development of air-cooled systems could be an important achievement for low capacity applications. In this work, two types of air-cooled absorber have been modelled: (i) falling film flow; (ii) bubble flow. The two models have been validated with experimental data obtained from a developed testing device and published numerical results of other authors from another model. The agreement is acceptable for both cases. Finally, a parametric study has been done for air-conditioning and refrigeration in a mobile application taking advantage of the exhaust gases of the engine. In both cases, the performance of the bubble absorber has been higher.

    This paper is devoted to the presentation of a new model for fin-and-tube evaporators, focusing on the solid core simulation and its integration with a quasi-homogeneous two-phase flow model for the in-tube refrigerant flow. Special attention is dedicated to separated in-tube flow patterns (stratified, stratified-wavy), because of their importance in liquid overfeed evaporators and the impact on the solid core temperature distribution. The paper presents the solid core formulation and numerical method, the intube two-phase flow model, and describes the proposed integration algorithm between them. A selected single-tube case is analysed in full detail, showing the impact of stratified flow on the fin and tube temperature distributions. Additional studies are finally presented on fin-tube contact aspects as thermal contact resistance and partial contact.
