Literature review of building peak cooling load methods in the United States

摘要

Today, sizing HVAC systems plays an important role in the building design process, requiring an accurate method in order to avoid problems from over- or under-sized systems. To date, there have been five peak cooling load methods published by ASHRAE, including: the Total Equivalent Temperature Difference/Time Averaging Method, the Transfer Function Method, the Cooling Load Temperature Difference/Solar Cooling Load/Cooling Load Factor Method, the Heat Balance Method, and the Radiant Time Series Method. This study provides a thorough review of the five methods with respect to their history and summarizes the method differences that can lead to inaccurate sensible cooling load calculations.
