Purpose and Scope

The purpose of this chapter is to present the basic features of air-handling processes and equipment. The aim is to provide a link between the basic theories of air-handling processes, presented in Chapter 4, and the actual equipment covered in the Systems and Equipment book. 

This chapter deals with the basic air-handling processes filtration of particles and gaseous substances from the supply and recirculated air, air heating and cooling, heat-recovery processes, and humidification and dehumidification. It also describes fans and ductwork. 

This chapter deals with the essential factors in the selection of systems and equipment during the design stage principles of controls, noise-reduction systems, and problems such as erosion, corrosion, maintenance and equipment cleaning, etc. 

Safety issues are not covered here. These are dealt with in Systems and Equipment book, and some fundamental issues will be taken up in the second edition of the Fundamentals book. The following aspects should be taken into account in system design fan safety AHU fire protection issues safety measures in mines, tunnels, underground car parks, etc. transportation of chemical and explosives. 

The basic topic of this chapter is theoretical aspects of air handling units, ductwork design, and the optimization of building energy systems.

However, a November 15-23, 1999, preapproval FDA inspection of BioPort s manufacturing renovations, which was more focused in scope and purpose than the 1998 surveillance inspections, resulted in BioPort receiving a FDA form 483 report with observations and possible deviations in some of the following areas validation, failure... 

The level of detail of the uncertainty analysis should be based on a tiered approach and consistent with the overall scope and purpose of the exposure and risk assessment. 

Scenario uncertainty Uncertainty in specifying the exposure scenario that is consistent with the scope and purpose of the assessment. 

The definition of the scope and purpose of each exposure assessment provides the specifications for building the exposure scenario, which represents the real-life situation that is to be assessed and provides the boundary limits of the assessment. As pointed out... 

The scope and purpose of the exposure assessment inform the formulation of one or more scenarios for which exposures are to be estimated. The exposure estimation approach should be capable of faithfully representing the key structural assumptions of the scenario, such as exposed population, agents to be considered, spatial and temporal scope, microenvironments and so on (see section 3.2.1 for a complete list). If the modelling approach omits any of the relevant elements, then the estimates could be biased. If the modelling approach includes irrelevant, unnecessary or superfluous elements, then, at best, the model is likely to be more cumbersome to deal with than it needs to be, or, at worst, biases may be introduced. 

With minor exceptions, the samples handled in a radiochemical laboratory are eventually measured with radiation detection instruments. The types of counting equipment in the counting room depend primarily on the scope and purpose of the radioanalytical chemistry laboratory mission. Common detectors of this type are listed in Table 2.1.

These other meetings did not aim at the same broad scope and purpose as envisioned for our GRC on Computational Chemistry. 

In goal definition, the scope and purpose of the LCA is defined. The functional unit and system boundaries are also established. The functional unit is the reference point to which environmental impacts are attributed. The choice of functional unit depends on the application of the LCA. For a process it could be a tonne of product or feedstock, or a tonne of impurity removed. For a commodity product the functional unit could be a tonne of product, but for specialty chemicals and most consumer products performance properties are more important and the choice can become complex. For example, performance of a paint would be related to its surface coverage and durability hence a possible functional unit for the paint might be the quantity required to cover a square meter of surface over a time span of 20 years.

In general, personal data are prohibited from being shared without consent, and typically collection of personal data must be legitimately explained as to its scope and purposes. Here is an example list of well-known and oft-cited privacy laws around the world ... 

There are many other approaches to the modeling of skin permeability data (permeabihty coefficients and others). It is beyond the scope and purpose of this chapter to review fully these approaches refer to the recent articles by Geinoz et al. (2004), Moss et al. (2002), and Vecchia and Bunge (2003a) for further details. Although in no way a comprehensive review, the following discussion is of notable other approaches used to model skin permeability. 

A brief description of the function of the platform process should be included. The description should uniquely identify the scope and purpose of the particular platform. 

As mentioned already in the previous chapter, time does not play a role in the formulation of equilibrium conditions. The mass and energy balances and the maximum conversion rate that can be achieved when the system is in thermal equilibrium are therefore not sufficient to define the dimensions of the best suited coal gasification equipment, which will here be termed the gas generator. A knowledge of how the gasification reactions proceed with time is therefore indispensable. To measure and, wherever possible, calculate this dependence on time is the object of reaction kinetics. Dealing with details of kinetic laws would go beyond the scope and purpose of this book and the reader should turn to the relevant literature [1.4]. 

Safety committees Is the scope and purpose of a group of individuals in the company that review and support safety procedures and ensure that safety is incorporated into daily activities and integrated across the enterprise. They support the safety representatives. Safety committees can be ad hoc, temporary, or permanent, depending on the need and purpose. 

Since a sufficient statement of the connections would go beyond the scope and purpose of these details, only the qualitative statement to be met here is that the use of highly viscous operating liquids increases the power dissipation loss. In case of doubt, an interpretation by the manufacturer is required.
