TC 5.7 is involved in many different types of activities. For this reason, information about each activity can be found in the following categories:
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.
HVAC Applications: Evaporative Cooling
Evaporative cooling is energy efficient, environmentally friendly, and cost effective in many applications and all climates. Applications range from comfort cooling in residential, agricultural, commercial, and institutional buildings, to industrial applications for spot cooling in mills, foundries, power plants, and other hot environments. Several types of apparatus cool by evaporating water directly in the airstream, including (1) direct evaporative coolers, (2) spray-filled and wetted-surface air washers, (3) sprayed-coil units, and (4) humidifiers. Indirect evaporative cooling equipment combines the evaporative cooling effect in a secondary airstream with a heat exchanger to produce cooling without adding moisture to the primary airstream.
HVAC Systems and Equipment: Evaporative AirCooling Equipment
This chapter addresses direct and indirect evaporative equipment, air washers, and their associated equipment used for air cooling, humidification, dehumidification, and air cleaning. Residential and industrial humidification equipment are covered in Chapter 22.
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.

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.
TC 5.7 is responsible for the following standards.
ANSI/ASHRAE Std 133: Method of Testing Direct Evaporative Air Coolers
ANSI/ASHRAE Std 143: Method of Test for Rating Indirect Evaporative Coolers
Proposed Standard 212P: Method of Test for Determining Energy Performance and Water-Use Efficiency of Add-On Evaporative Pre-Coolers for Unitary Air Conditioning Equipment.
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.
Hot Climate Design Guide
This MTG will coordinate TC/TG/TRG technical Activities to help support the development of the technical basis and adoption of the Hot Climate Design Guide. Responsibilities include suggestions for Research, Development and Presentations and special publications detailing aspects of the Hot Climate Design Guide.
