This paper presents a method for a more accurate calculation of air exchange in the mechanical ventilation of industrial halls with uniformly distributed heat load. The method has been developed on the basis of finding the relation between the
Ventilation studies using small-scale water models have, especially in Norway gained new and important knowledge in industrial ventilation the last 15 years. The outcome has been twofold. First of all it has resulted inimportant experience
Several papers discussing ventilation efficiency, effective industrial ventilation, the positioning of ventilation inlets and outlets, displacement ventilation and other applications of the concept of ventilation efficiency.
Discusses problems of condensation in cavity roofs of industrial buildings, including ventilation air as a moisture source. Lists points to watch when foam filling the cavity.
A handbook of constuction techniques for achieving a low air change rate and good insulation in steel buildings. Insulating materials and how to avoid cold bridges are discussed. Air leakage, moisture problems and comfort questions are also considered. Examples are presented of a small industrial building andof a tennis hall.
Energy efficient steel buildings with better thermal insulation to reduce transmission losses are now being built in Sweden. Examples of structural design are given to minimise the influence of thermal bridges. A method for the calculation of such heat losses is presented. Principles for airtightness to reduce air leakage of buildings are discussed, special details and material requirements are given.
Computer programs INFILS and ACFES2/R have been developed for the analysis of industrial buildings' heating loads and energy consumption relating to air infiltration. The heat demand computation results for typical hall structures are presented. It is shown that on windy days with low outside temperatures, total heat losses rose to 180% of basic heat losses. The necessity of developing proper methods for designing, building and testing elements of industrial buildings is emphasized.
Industrial buildings, particularly those containing nuclear and process plant, often require high standards of ventilation in order to cope with unusual features of the operations or process which take place within the buildings.
Discusses strategy for dealing with indoor air pollution in office and similar buildings, including verification of the mechanical ventilation system, measurement of building pressure, problems due to stack effect, presence of moisture. Suggests that the causes and cures of indoor pollution are diverse and surprisingly simple. Mechanical ventilation systems should be less complex, have dynamic stability and correct uncontrolled excessive moisture.
Addresses air leakage of warehouses and light industrial buildings including the significance of infiltration/exfiltration, air leakage sites, and measurement techniques. Concludes that 1, only limited leakage data are available for components of this building category 2, no model has been developed specifically for use in warehousing and light industrial buildings. However, one of the existing models for residential buildings could possibly be adapted.
