Computer Evaluation of Results by Room Thermal Stability Testing
2017
The paper deals with the use of computer tools for assessing of the thermal stability of buildings. It describes the procedure developed for determining of a time constant for cooling down of the room and a coefficient α whose values are related to the building’s thermal-accumulation properties. The developed methodological procedure is based on processing of the data obtained by measuring in the real building object, computer simulations in COMSOL Multiphysics software and subsequent processing of the output data in MAPLE and MATLAB software with regard to compliance with valid European and Czech technical standards used in building industry and Architecture. The studied model of the room showed the dependence of the time constant and the coefficient α on thickness and specific heat capacity of the thermal insulation of the external wall under the selected winter conditions. The studied example also proved correlation between the coefficient α and the time constant of the room.
Parameterization of module for testing of thermal stability in the room
2014
The paper deals with testing of the thermal stabilization of buildings by using COMSOL Multiphysics software. It describes the possibilities to parameterize the module for simulation the temperature distribution in a room heated by two heat sources. A parameterized model allows you to change the requirements of the geometric dimensions of all elements of the module and their spatial distribution, as well as a choice of physical properties and pasting real measured data needed to assess the distribution of temperature in the room depending on the ambient temperature and the heat input of the considered sources. Parameterization enables to insert all necessary data into COMSOL Multiphysics by using external txt files, which can be up to this end through a helper application in Microsoft Excel. Linking program COMSOL Multiphysics with applications created in Microsoft Excel allows comfortable loading parameters to external users via a web interface without knowledge of the work environ...
Indoor Air Temperature Distribution an Alternative Approach to Building Simulation
Revista de Engenharia Térmica, 2003
The current paper presents a model to predict indoor air temperature distribution. The approach is based on the energy conservation equation which is written for a certain number of finite volumes within the flow domain. The magnitude of the flow is estimated from a scale analysis of the momentum conservation equation. Discretized two or three-dimensional domains provide a set of algebraic equations. The resulting set of non-linear equations is iteratively solved using the line-by-line Thomas Algorithm. As long as the only equation to be solved is the conservation of energy and its coefficients are not strongly dependent on the temperature field, the solution is considerably fast. Therefore, the application of such model to a whole building system is quite reasonable. Two case studies involving buoyancy driven flows were carried out and comparisons with CFD solutions were performed. The results are quite promising for cases involving relatively strong couplings between heat and airf...
Dynamics of Air and Wall Temperatures in Multiroom Buildings
Volume 10: Emerging Technologies and Topics; Public Policy, 2012
Temperatures have been recorded every five minutes in a number of rooms in a student dormitory. The experimental data are presented as an example of room temperature dynamics in a large multi-room building. Statistical analyses of the data have been carried out to provide auto-correlations of individual room temperatures, its power spectral density, histogram, and the cross-correlations between the temperatures in neighboring rooms. A fairly complicated behavior is observed. A parallel, simplified mathematical model is set up for air and wall temperatures in multiple rooms to explain the temperature dynamics. Each room has an independent heater that switches on and off at certain lower and upper limits, respectively. The governing equations are based on energy balances with heat exchanges occurring between the air in a room and the walls surrounding it, and with the exterior. The instants at which heaters switch on or off are determined by the temperatures, leading thus to a non-linear set of equations. The governing equations are non-dimensionalized to provide the significant non-dimensional groups of the system: there are two which characterize the problem. Limiting solutions for large and small values of these groups provide physical explanation for the effect of the walls. Numerical solutions of this set of first-order ordinary differential equations are easily obtained, and examples of this are shown. The results show that there are still other physical effects to be considered before theory and experiments can be reasonably compared.

Buildings Thermal Simulation Using Thermal Networks Method
This study focuses on a mathematical model applied to a room, which may be part of a building in Baghdad at a typical hot day on 30 August. The model elements were analyzed by an electric circuit analogy of the thermal networks. The parameters of the room thermal simulation model have been tracked through hourly calculation of the heat balance. Sets of simulation equations were obtained, using a fully implicit scheme, and implemented in a sophisticated MATLAB program. The study was conducted by varying the wall thickness, thermal capacity, ..etc. the output was revealed as an indoor, inside surface, outside surface temperature as well as heat flux through the wall. The walls and the roof of the room model were exposed to the outdoor. the room is assumed to be without furniture, people or any supplementary heat. As a result, important conclusions have been drawn indicating the influence of thermal mass of wall and roof, thermal insulation, suspending ceiling, outer surface color, windows and their shading devices on indoor thermal behavior.
DOMUS 2.0: A WHOLE-BUILDING HYGROTHERMAL SIMULATION PROGRAM
Recent advances in mathematical models, computer processors and OOP compilers have been motivating the development of the Domus program for wholebuilding hygrothermal simulation. The Domus program for simulation of multi-zone buildings has been developed in c++ language under C++ Builder environment, which is a fast and precise easy-to-use compiler. The program is available on the PC platform under Windows 9x and NT operating systems. The user interface consists of a series of windows in which the user can enter the relevant input data and review the results. The user can move between other applications when the Domus simulations are running and several Domus projects can be open and running at the same time due to the independence of the graphical interface and the thermal simulation engine. Domus projects with all their input information and results may be saved and reopened. The Domus former version allows the calculation of building thermal and energy performance, neglecting moisture effects. In this Domus version, the interface has been considerably improved so that simulations can be performed in a very-easy way. Additionally, the Umidus program features have been inserted into the Domus code, allowing it to take moisture effects into account. In Conclusion, Domus interface is presented and a hygrothermal simulation of a 3-storey building in discussed.
Analytical and inter-program validation of a building thermal model
Energy and Buildings, 1987
Results from the analytical and interprogram validation of a building thermal model (CBS-MASS) are presented. Within the analytical validation, the analytical solutions of the steady-state and the transient heat transfer through the exterior walls of an intermediate floor room are compared with the predictions of the computer program. The analysis of the transient process concerns the response of the room air temperature and the inside surface temperature of walls subjected to step-function change of outdoor conditions. Good agreement between the analytical solutions and the simulation results indicates that the basic heat transfer processes are well simulated by the computer program. The inter-program validation deals with the comparison between the estimations of the space thermal loads in one office space provided by the CBS-MASS program against the predictions of two well-known programs used in the thermal analysis of buildings: BLAST and TARP. The results show good agreement between the predictions of these programs. Hence, the analytical and interprogram validation indicates that the CBS-MASS program provides good estimation of the thermal behavior of buildings. 0378-7788/87/$3.50
Space heating and ventilation 3D-simulation for an office room
2020
In order to study thermal conditions and air flows in a 4 m x 5 m x 3.5 m (height) size office room, 3D FEM simulation model was created. The room is enclosed by walls, floor and ceiling which thermal characteristics are specified by typical heat transfer coefficients and specific heat capacities. Space heating is generated by an electric heater which control is based on on/off-controller and a temperature sensor. Air ventilation is based on constant air flow which volumetric speed is set by the requirements of the national building code. Non-uniformity of room temperature and air conditioning cause discomfort of occupants and loose of energy efficiency. Multiphysics simulation combining thermal and CFD simulations may reveal possible thermal imbalance and undesirable air flows in the room.Peer reviewe
