The Complete Applications-Oriented Resource for Load Calculations This second edition of Load Calculation Applications Manual, available in both I-P and SI units, is an in-depth, applications-oriented reference that provides clear understanding of the state of the art in heating and cooling load calculation methods, plus the tool and resources needed to implement them in practice. $119 ($97 ASHRAE Member) / 360 pages / 2014 Updates for this edition reflect in information from the 2013 ASHRAE Handbook—Fundamentals, including lighting, materials, and equipment used in buildings today, as well as new methods available since the first edition. This reference serves as a basic refresher course for those who use psychrometrics on a recurring basis and provides a four- to six-hour psychrometrics learning module to students; air-conditioning designers; agricultural, food process, and industrial process engineers; meteorologists and others. This text provides an understanding of fundamental HVAC concepts and how to extend these principles to the explanation of simple design tools used to create building systems that are efficient and provide comfortable and healthy environments.

This method was developed as a simpler calculation alternative to difficult and unwieldy calculation methods such as the transfer function method and the method. Error when using the CLTD/CLF/SCL method tends to be less than twenty percent over and less than ten percent under.

History [ ] After its introduction in the 1979 handbook, research continued on increasing the accuracy of the CLTD/CLF method. Research completed in 1984 revealed some factors which were not accounted for in the original publication of the method; these findings were a result of the research project 359. In 1988 Research Project 472 worked to correct these oversights with the introduction of a classification system for walls, roofs, and zones. Additionally, a weighting factor database was generated to help correct for previous inaccuracies.
