LoginThis paper discusses a methodology to support the performance assessment of ventilationsystems of operating rooms (ORs), with a further focus on the application of numericalsimulation tools in this design assessment.
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 principles behind a new design of isolation room are set out. The process ofvalidating the design is described using a range of physical modelling techniques.
This text contains attainments from indoor climate and air conditioning equipment monitoringin clean rooms in the public health service. The editor is designer of HVAC systems inthe modern hospital near Brno in the Czech Republic.
This paper presents design considerations of ventilation and indoor environmental quality(IEQ) for a control center. Raised access floors are extensively used to provide flexibilitiesfor control cables and wires required by a control center.
Three dimensional simulation of flow and material dispersion processes inside the enclosuresof machine tools opens up perspectives of assessment not by far achievable experimentally.Visualisations of these processes in terms of velocity and direct
The subject of this paper is the numerical simulation of the capture of contaminants with a local exhaust system. The objective is to evaluate the influence of multi-slotted hoods on the capture efficiency and its impact on indoor air quality.
Cfd-calculations were performed to test whether it is possible to separate a non-smoking zone from a smoking zone using an air curtain. The cfd-calculations resulted in the following conclusions: 1. A larger exhaust flow is best. 2.
The design of buildings for animal keeping and the dimensioning of ventilation equipment forsuch buildings require knowledge about heat, moisture and CO2 production of the animals.
A research project has been carried out to develop new methods and technical solutions torefurbish ventilation and air-conditioning systems of office and commercial buildings builtduring 1970`and 1980`.
The relationship between construction activities and an increased risk of microbial contamination and degradation of air quality in new building construction and renovation projects was studied.
The objectives of this study are to reproduce in the laboratory different levels of cleanliness innon-porous ducts of HVAC systems, to compare a new method for sampling surface dust inducts with those methods cited in the literature, to compare th
The published REHVA guidebook provides comprehensive uptodateinformation aboutdesign features, criteria for cleanliness, inspection and cleaning instructions of ventilationsystems.
Man made mineral fibers (MMMFs) that can cause irritation in upper respiratory tract, eyesand skin, can be emitted to indoor air from the HVAC system.
The sources of man-made mineral fibres (MMMFs) settled on furniture surfaces and in supply air were determined in an office building. The impact of renovation on indoor air and the perception of air quality by the occupants were studied.
Since the study by P.O Fanger (1988) [1] we know that the Heating Ventilating and AirConditioning (HVAC) system could be responsible for a large amount of indoor air pollutionand Sick Build Syndrome (SBS).
Cleaning ventilation system ductwork has been a topic of controversy for several years. Guidance documents are available for duct cleaning, but uniformity in application of remediation and cleaning methods is inconsistent in many cases.
The effectiveness of UV radiation lamps in order to reduce fungal contamination of HEPA filters, to extend filter efficacy and to reduce maintenance costs, is experimentally studied by means of a dedicated air conditioning unit.
Entrance of snow into the HVACsystemsis common problem in the arcticandsubarcticclimates and may cause moistening or wetting of filters and outdoor air chambers whichpromotes microbe growth.
This paper describes a methodology for improving individual thermal comfort in an officebuilding without increasing energy consumption.
Thermal comfort studies and standards show that room temperatures should be higher in thewarmer season than in the colder season. An interview survey with a sample size of 3,094people was performed in Finland.
