Cooling Load Estimation of Auditorium by CLTD Method and its Comparison with HAP and TRACE Software

Abstract

Heating Ventilation and Air Conditioning (HVAC) system is required to provide comfort conditions such as humidity, temperature and other environment parameters for occupants and machines. The necessity of design of such system is increasing day by day. To install air conditioning system for comfortable environment it is mandatory to estimate the total cooling load of building. Cooling Load Temperature Difference (CLTD), Radiant Time Series (RTS) and Total equivalent temperature difference (TEDF) are different methods to calculate the total cooling load. In this study we explained CLTD method to calculate cooling load of an auditorium. The design of Auditorium is developed by AutoCAD software. Total cooling load of auditorium is calculated by CLTD method and results are validated with Hourly analysis program (HAP) and Trace 700 software.
