Publisher's Synopsis
The main factor that influences the quality of the indoor environment is the thermal climate which is determined by air temperature, relative humidty and air movement. A controlled and regulated indoor environment is necessary for human comfort and health, for living plants and pets, and for furniture and equipment. It is crucial, therefore, that effective environmental designs are achieved.;An important variable for thermal comfort and the well-being of humans is the level of moisture in the air. Air that is too dry can cause respiratory problems, skin and hair dryness and eye irritation. Too high levels of humidity can also cause respiratory ailments, thermal discomfort and condensation. Aside from human considerations, humidity levels affect wooden furniture, paintings, fabrics, paper and mould growth. Hence, the control and maintenance of relative humidity in buildings, factories and warehouses is essential for thermal comfort and health, various processes (industrial, chemical, food and electronics) and the protection of the built environment.;Appropriate humidity levels within buildings may be achieved by either active or passive means. The route chosen is dependent upon whether there is air conditioning in the building, the process undertaken within the building, the degree of control required and the prevailing climatic conditions.;This application guide identifies the factors relevant to humidification for a broad range of humidification applications, and sets out a procedure for the selection of humidifiers. In addition, other salient topics, such as health hazards are also covered in some detail, together with good practice guides.
