Numerical study of circular jet diffuser for task ventilation of under-floor air supply system in tropics | 2007 | English
Bases on the concept of task/ambient ventilation, fresh air can be decoupled from re-circulated air so as to improving ventilation effectiveness in breathing zone.
Modeling human exposure to particles in indoor environments using a drift-flux model | 2007 | English
This study developed a drift-flux model for particle movements in turbulent indoor airflows.
While the scientific literature is full of studies looking at the impact of climate change driven by human activity, there is very little research on the impact of climate change or urban heat island on building operation and performance across th
The daylight coefficient method has been introduced in computer simulation as an efficient approach to compute indoor daylight illuminances through building static fenestration systems.
Over the past 15 years, much scientific work has been published on the potential human impacts on climates.
According to the Czech legislative act the operative temperature is the evaluation criterion for thermal comfort in air-conditioned or heated spaces.
Plant optimization program (pop) and its application in rate model for a large district energy and combined heat and power system | 2007 | English
District energy systems provide commercial and residential space heating, air conditioning, domestic hot water, steam, and industrial process energy, as well as sometimes co-generating electricity in systems.
Computational approach for determining the directionality of light: directional-to-diffuse ratio | 2007 | English
The directionality of light is defined as the balance between the diffuse and directional components of light within an environment. It is an indicator about the spatial distribution of light flow onto an element or into a space.
The airflow network model in EnergyPlus provides the ability to simulate multizone wind-driven airflows. The model is also able to simulate the impacts of forced air distribution systems, including supply and return air leaks.
In the design of indoor winter sports facilities Computational Fluid Dynamics (CFD) simulations are used to calculate the velocity and temperature distribution throughout the space, in order to complement traditional mechanical design and increase
Utilizing high performance supercomputing facilities for interactive thermal comfort assessment | 2007 | English
We outline the current state of the development of a computational steering environment (CSE) for the interactive simulation and local assessment of indoor thermal comfort.
Dynamic simulation of blind control strategies for visual comfort and energy balance analysis | 2007 | English
The presented study describes a method for evaluating control strategies for shading devices.
Variable Refrigerant Volume(VRV) air-conditioning system is more liable to meet thermal environment problem than other systems such as split-type air-or window-type air-conditioner because its capacity of outdoor unit is much higher.
Pressure coefficients (CP) are fundamental to calculate ventilation rates in buildings by the airflow network models (AFN).
In this study, the characteristics of the movement of chemical compounds in the concealed spaces and indoor spaces in houses were investigated using building cut models and a simulation program Fresh2006. The equivalent leakage areas in the concea
An existing computer model for dynamic hygrothermal analysis of buildings has been extended with a multizone airflow model based on loop equations to account for the coupled thermal and airflow in natural and hybrid ventilated buildings. In water
A full-scale test room is used to investigate experimentally and numerically the velocity and temperature fields in the case of a mechanical ventilation.
