Fundamentals and Applications

In order to be able to evaluate and maintain the efficiency of a chilled water system, you must know how to measure the many variables for comparing the operation. ASHRAE has developed standard methods of testing field performance and test stand performance of liquid chilling equipment and systems. These Standards are Standard 184 and 30. The 41 Series of Standards describes methods for testing system variables such as liquid and airflow, temperature and humidity. The presenters in this seminar describe these Standards and their development and use.
1 ASHRAE Standard 30
 |
Phillip Johnson, P.E., McQuay International |
Publication of Standard 30, Method of Testing for Liquid Chilling Packages, is pending a second public review period. Significant changes have been made to this method of test (MOT) for chillers that was last published in 1995. A summary overview will guide users through the testing requirements.
2 ASHRAE Standard 184
 |
Robert Blanton, P.E., Johnson Controls Inc |
ASHRAE Standard 184 is the Method of Test for Field Performance of Liquid-Chilling Systems. It has been under development and is now in the final stages and public review before being published later this year. This Standard differs from Standard 30 in that it applies to chillers in their actual field installation and operation rather than the "bench" testing done under Standard 30. This speaker will present an overview of this Standard that will be valuable to system Owners, Engineers, and Designers.
3 41 Series Standards

Most ASHRAE members may not be aware of ten basic measurement standards beginning with Standard 41.1, Standard for Temperature Measurement, and including 41.2 through 41.11 standards for measuring pressure, airflow, air velocity, humidity, gas flow, liquid flow, refrigerant flow, and power. This presenter describes the utility of each of these standards for application to product testing and for incorporating into other ASHRAE testing standards. Revised versions of all of these standards have been published since 2013 and are current and useful.
