INTRODUCTION
This sof t ware is developed by Emerson
Climate Technologies to assist in calculation
of heat of any building. It has weather data
of 44 countries in Asia.
Easy step -by-step
input of building parameters allows OEMs
sales engineers to calculate the precise load
requirement and help them decide on an
optional system for building.

ABOUT THE MANUAL
This Manual aims to provide the user sufficient
information about the use of the Heat Load Calculating
Tool® (HLCT) developed by Emerson Climate Technologies.
With the aid of this tool, engineers can compute the Heat
Load of any building and provide a summary of all Heat Load
Computations.
This Manual will help the user quickly adapt to the HLCT
environment by providing step-by-step instructions on how
to design a project, how to properly input data, and how to
preview and print the summary of results.
