The ASHRAE Handbook is published in a series of four volumes, one of which is revised each year, ensuring that no volume is older than four years.
The Handbook can be purchased at the ASHRAE Bookstore by clicking on this link.
The handbook is one of the most important communication vehicles between the Society and its members. The present challenge is to make certain that the chapter covers all the of the basic fan design and application theory is terms that are clear to most people. Some future challenges include a smooth transition toward the use of an electronic Handbook with the possibility of an interactive presentation.
This TC is responsible for the following chapter in the HVAC Systems & Equipment Volume
A fan is a device that uses a power-driven rotating impeller to move air. The impeller does work on the air, imparting to it both static and kinetic energy, which vary in proportion, depending on the fan type.
Comment on the Handbook: ASHRAE welcomes your comments on the Handbook or a specific Handbook chapter. To submit a comment about any aspect or part of the Handbook series, you can use the Handbook Comment Form.
Review a Handbook Chapter: To provide your feedback about a specific Handbook chapter, you can answer the brief survey questions on the Handbook Chapter Review Form.
Technical committees develop and sponsor technical sessions at the winter and annual conferences. Information about their future technical program is discussed at each TC meeting and at the TC’s Program Subcommittee meeting.
The following is a sample of past TC 5.1 sponsored programs
Chicago 2018: Seminar 29, Fan Energy Savings and System Efficiency Increase by Using the Fan Energy Index.
Las Vegas 2017: Seminar 25, Wire-to-Air Fan Powered Performance Consumption.
Chicago 2015: Seminar 2, Fan and System Integration for Maximizing Energy Efficiency Design; Seminar 28, System Effects from Inlet of Centrifugal and Plenum Fans.
Dallas 2013: Seminar 7, Designing Energy Efficient Ventilation Systems for Transportation Using Jet Fans.
Denver 2013: Seminar 31, Laboratory Exhaust Fans and Energy Conservation.
ASHRAE publishes papers and transactions from presentations at its conference events. In addition, ASHRAE records most of the seminar sessions from its conferences on DVD. These DVDs are ideal for use at chapter meetings, in university courses, or company lunch and learns. Products available from the most recent conference may be found here.
Technical Committees are responsible for identifying research topics, proposing research projects, selecting bidders, and monitoring research projects funded by ASHRAE. Information about their specific research program is discussed at each TC meeting and at the TC’s Research Subcommittee meeting.
This TC has the following active research project:
Work Statement (WS) 1769: Experimental Evaluation of the Part Load Efficiecy of V-Belt Drives used on Fans
RTAR's in progress
-RTAR 1829: Inlet and Outlet Air and Sound system effects on multiple plenum fans parallel arrangement
-Cosponsored RTAR with TC 9.1 (Laboratory Systems): Charactorizing the Performance of Entrained Flow Stacks
-Cosponsoring of RTAR with TC2.4 (Particulate Air Contaminants and Particulate Contaminant Removal Equipment): Energy Implications of Air Filtration in Commercial Buildings
--Plenum fan spacing guidelines, espically parallel arrangements
The Long Range Planning Subcommittee is charged with setting long range goals for our TC. They regularly solicit opinions from all concerning the future needs of fan designers and users. Some of their ideas follow:
1. To establish a far better model for fan sound prediction based on detailed test results. One test would be on Axial flow fans and another based on Centrifugal fan design.
2. A program of introducing some form of interaction to our chapter of the ASHRAE Handbook.
3. Adding fan interactive application education to our website.
4. To launch a program to promote fan efficiency as a significant factor for power reduction.
5. To build a network with local chapters to promote better fan applications using Power Point and other aides.
ASHRAE writes standards for the purpose of establishing consensus for: 1) methods of test for use in commerce and 2) performance criteria for use as facilitators with which to guide the industry. ASHRAE publishes the following three types of voluntary consensus standards: Method of Measurement or Test (MOT), Standard Design and Standard Practice. ASHRAE does not write rating standards unless a suitable rating standard will not otherwise be available. ASHRAE is accredited by the American National Standards Institute (ANSI) and follows ANSI's requirements for due process and standards development. Standards may be purchased at the ASHRAE Bookstore.
This TC is cognizant or co-cognizant for the following standards:
ANSI/ASHRAE Standard 51: Laboratory Methods of Testing Fans for Certified Aerodynamic Performance Rating (AMCA Lead)
ASHRAE Standard 68: Laboratory Method of Testing to Determine the Sound Power in a Duct (AMCA Lead)
ANSI/ASHRAE Standard 149: Laboratory Methods of Testing Fans Used to Exhaust Smoke in Smoke Management Systems (TC05.06 Co-cognizant)
Include other activities, such as MTG involvement, into this section.
