LoginA simulation model is developed that allows to investigate the infection risk for Legionella Pneumophila in the design phase of a DHW system and to test the effectiveness of disinfection techniques on an infected system.
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.
The major goal of this study is to demonstrate the feasibility of the dynamic modeling and simulation of both conventional and direct exchange geothermal heat pump applications particularly with regard to performance evaluations.
Building performance simulation has been utilised for the investigation of thermal comfort and airflow within a naturally ventilated, self-sufficient house in a bushfire prone area.
The exponential increase of the cooling demand in buildings obliges to find alternatives to the high electricity consumption with air conditioning systems. This work investigates a new cooling system based on evaporation.
In some areas of high air condition adoption there is potential for night purge natural ventilation to reduce the number of hours that the air condition system is operated, leading to a reduction in energy usage and associated carbon dioxide emiss
This research aims to define a modelling approach to simulate District Cooling Systems (DCS). A model of the network has been developed using the equation-based object-oriented language Modelica.
Thermal performance of Earth Air Tunnel Heat Exchanger (EATHE) under transient operating conditions depends upon the shape of thermal influence zone within the soil domain around the buried pipe.
This paper presents a simulation-based study of a decentralized, „low-exergy‟ (or LowEx) space cooling system for a commercial office currently under construction in Singapore.
Among passive strategies to reduce energy consumption in buildings, we focus on natural ventilation, which can bring an important decrease in temperature during summer depending on climate.
This paper deals with a numerical and experimental study of the thermal performances of an Earth-to-Air Heat Exchanger (EAHX) connected to a country house in Marrakech (31°37' N latitude and 8°2' W longitude).
Contamination distributions were calculated and evaluated by contamination area ratio at respiration height for actual smoking rooms. As a result, 1) Dust contamination area ratio is about 20 % for required ventilation volume by Guidelines.
Nowadays building simulation tools have been proven to be very effective in the planning process of building projects to find optimal solutions for the buiding design.
The paper presents a laboratory investigation about cork-cement mixtures designed for building applications. Samples are prepared by mixing cork aggregates, sand, cement and water.
Automated Calibration of Air Handling Unit Models using A Modified Preisach’S Model | 2015 | English
This paper presents a new approach to calibrate air handling unit models. This approach studies every heat exchanger component separately based on the inverse problem framework, the Preisach model of hysteresis and machine learning techniques.
In Europe, the increasingly restricting environmental regulations push the residential building sector to replace pollutant fossil fuel boilers with more environmentally friendly technologies.
Most controllers in Heating, Ventilation and Airconditioning (HVAC) applications remain the Proportional-Integral (PI) type.
This paper introduces a longitudinal study monitoring occupants’ window opening behaviour in a mixed-mode office building in Beijing, China, when natural ventilation is specifically used for controlling the building’s indoor thermal environment.
This paper investigates how advanced HVAC systems and predictive control can influence the interaction between a house and the grid. The case study corresponds to a house in Toronto, Ontario, Canada, analysed during the heating season.
The integration of two technologies - the Airconditioning Duct System and Optical Mirror Duct System - into a new energy-saving system “Integrated Optical Air Duct System” (IOAD) significantly reduces the lighting energy, which accounts for roughl
The increasing number of highly insulated and air tight buildings leads to the concern of indoor environment overheating. This research studies the possibility of applying natural ventilation as a way to avoid high temperatures indoors.
