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.
This TC is responsible for the following chapters in the HVAC Systems & Equipment Volume
The condenser in a refrigeration system is a heat exchanger that rejects all the heat from the system. This heat consists of heat absorbed by the evaporator plus the heat from the energy input to the compressor. The compressor discharges hot, high-pressure refrigerant gas into the condenser, which rejects heat from the gas to some cooler medium. Thus, the cool refrigerant condenses back to the liquid state and drains from the condenser to continue in the refrigeration cycle. Condensers may be classified by their cooling medium as (l) water-cooled, (2) air-cooled, (3) evaporative (air- and water-cooled), and (4) refrigerant-cooled (cascade systems). The first three types are discussed in this chapter; see Chapter 48 in the 2010 ASHRAE Handbook—Refrigeration for a discussion of cascade-cooled condensers.
A liquid cooler (hereafter called a cooler) is a heat exchanger in which refrigerant is evaporated, thereby cooling a fluid(usually water or brine) circulating through the cooler. This chapter addresses the performance, design, and application of coolers.
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
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
Some past programs sponsored by this TC
Forum: Low GWP Refrigerants: Current Status and Future Path, Chicago 2012
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.
1677-RP: MEASUREMENT AND PREDICTION OF WATERSIDE FOULING PERFORMANCE OF INTERNALLY ENHANCED CONDENSER TUBES USED IN COOLING TOWER APPLICATIONS
The objective of this research project will be to propose a generalized calculation procedure or approach to determining an appropriate fouling resistance for a “typical” application of enhanced tubes in a cooling-tower water heat exchanger application.
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 for the following standards
ANSI/ASHRAE Standard 22: Methods of Testing for Rating Liquid Water-Cooled Refrigerant Condensers
ANSI/ASHRAE Standard 24: Methods of Testing for Rating Liquid Coolers
ANSI/ASHRAE Standard 181: Methods of Testing for Rating Liquid to Liquid Heat Exchangers
This TC is co-cognizant with TC 8.2 for the following standard
ASHRAE Standard 30: Methods of Testing Liquid Chilling Packages
This TC participates in the following Multidisciplinary Task Group
MTG.LowGWP: Lower Global Warming Potential Alternative Refrigerants
This MTG is established to coordinate TC/TG/TRG technical activities to help transition the HVAC&R industry to sustainable lower Global Warming Potential (GWP) alternative refrigerants. The MTG will further request participation from US EPA and AHRI. The MTG responsibilities include suggestions for research, development and presentation of technical programs of all types on alternative lower GWP refrigerants, suggestions for Life Cycle Climate Performance (LCCP) systems evaluation for different applications, development of lower GWP solutions for different applications, and a special publication detailing aspects of LCCP applied to the HVAC&R fields.
