LoginDesign of air conditioning systems for efficient and effective part-load operation poses a considerable challenge, but one which is frequently not appreciated by the designer tied to traditional design practices.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
Access to the publications is free of charge.
A method for evaluating solar rights and shading requirements in an urban environment is presented. The method is embedded in a CAD tool developed and adapted for this purpose.
An integrated simulation system for the building services design and facilities management purposes is being developed by Olof Granlund Oy.
The purpose of this study is to develop the technique that mixing energy loss is predicted at the time of the air conditioning system design by the simulation.
Simulation of cleaning is a new area in building simulations. To make rational cleaning is it important to know how difficult it is to clean rooms. I define a Cleaning Index (CI) as the cleaning area divided by the floor area.
This paper introduces a method to simulate the day-light performance of buildings using geostational me- teorological satellite images.
In order to explain the effect of ventilation systems and airtight performance of houses in detached houses, the investigation was made on a simulation program which calculates the ventilation rates and indoor air quality.
The research on provision of computational support for building performance analysis has traditionally concentrated on the building design phase. However, computational modeling can also effectively apply to the building operation phase.
It is important to apply the natural light effectively for the low energy consuming daylighting design.
Based on K- two equation turbulence model, we used PHOENICS 1.4 and numerically simulated air distribution and contamination field under different conditions in a vector- flow clean room.
Study into optimized control for air-conditioning system with floor thermal storage | 1999 | English
Air-conditioning systems with floor thermal storage can be used for cutting peak load and utilizing nighttime electric power.
In order to make proper radiative meshes with considering thermal distribution on solid surfaces, we inves- tigated the adaptive mesh generation method and per- formed parametric survey for a threshold which con- trols subdivision of mesh.
When some faults take place in a thermal storage HVAC system, changing pattern of the temperature profiles of the thermal storage tank is useful to infer where some faults exist.
This paper presents a mathematical model yielding a simplified representation of the thermal behaviors of ivy-covered walls. The model is integrated with a CFD program to implement simulation.
The use of split-type air-conditioners in new apartment buildings becomes popular in Hong Kong. One requirement for their effective use is satisfactory heat rejection at the outdoor condensing units.
An evaluation method for life cycle energy (LCE) and CO2 (LCCO2) of houses by the system dynamics (SD), a method for understanding how all the objects in a system interact with one another, was presented.
Building dynamic simulation has been available to building design engineers for some time.
The numerical model for the analysis of the combined convective-conductive heat transfer in the building components has been developed.
Nowadays architects commonly use the ‘coupled space concept’. Examples are mezzanines, half-open office spaces and exhibition rooms.
The paper outlines a two-year research program where Radiance was used in the conversion of Empress Place, a national monument in Singapore, into an Asian Civilisation Museum.
