ComfortAir HVAC software is designed to be used by
engineers, architects, contractors and energy auditors
to calculate and analyse heating and air conditioning
loads in all types of buildings. Input and output
units can be set independently to English or Metric
units. The program contains weather and other
necessary data for 1,989 cities and localities in 163
countries, thus making it applicable for virtually any
location in the world. Program output includes tables
and graphs of cooling loads (load profiles) for all
hours of the day and for all months. It also provides
summary reports for peak conditions and a host of
other useful information, such as reports and graphs
of glass shading, from external shading devices like
fins and overhangs. An example of how the hourly load
tables can be useful, is in the design of thermal
storage air conditioning systems, where ton-hour
(kilowatt-hour) calculations have to be made in order
to size the storage systems. The program is very user-
friendly and it provides several useful wizards to
make processes like data entry and U-value calculation
easy to carry out and less prone to error and
ommissions. Context sensitive Help illustrated by
diagrams where appropriate, is provided at the click
of a button. The program was developed as a multiple
document interface (MDI), allowing the user to open
and work on several projects simultaneously.
