Form #: 630-104
The intent of this chapter is to discuss various methods used in the field for air measurement. It is not the intent of the chapter to explain duct design & layout.
Form #: 630-137
Stated in basic terms, the purpose of a VAV system is to provide cooling where and when it is necessary. This chapter covers the types of terminal units (boxes); the three categories of pressure associated with air handling, Fan Laws, reheat coils, besides a having a section on equations, definitions & abbreviations.
Form #: 630-138
Most of the control types discussed in this chapter have certain principal elements in common. The main topics covered are: control operation in terminals, velocity controller operation, fan terminal flow control and direct digital control.
Form #: 630-139
Today’s VAV terminals usually are equipped with some type of direct digital control (DDC) package. This chapter provides troubleshooting and calibration information for Kreuter and Honeywell pneumatics and the control packages described in this chapter are typical of existing VAV controls. This chapter also gives the basic guidelines to follow when troubleshooting.
Form #: 630-146
If system cleaning is deemed necessary, this chapter offers information to understand the cleaning practices that will ensure maintenance of an insulated duct system’s structural and functional integrity.
Form #: 630-148
It is the goal of this chapter to offer an overview of the general principles of duct system design and to call attention to some of the special considerations that need to be given to the process to ensure a satisfactory result.
Form #: 630-149
This chapter attempts to deal with the problem of designing an air distribution system for a particular structure whether it is a small, large or multistory structure, and also tries to help the designer to select the best system type for each application.
Form #: 630-150
The goal of this chapter is to take some of the mystery out of the equal friction method of duct sizing. This can be accomplished by using the procedures outlined in this chapter.
Form #: 630-18
This chapter is confined to the low velocity duct system. Some of the topics covered: the function of a duct system, factors which affect resistance to air flow, types of duct systems which can be employed, preliminary layout of the duct system, and type of direct fittings to be employed.
Form #: 630-19
This chapter covers insulation design and the 3 factors that are related to it. Insulation design for ducts in air conditioning and forced warm air heating systems is affected by three considerations: Heating Saving, Protection Against Condensation & Sound Control. Each of these three factors represents a separate and distinct design problem requiring separate methods of solution and should be considered on any duct insulation.
