calculation must be made� A cooling heat gain
calculation determines the amount of heat needed
to be removed� A heat gain calculation also
calculates the extra heat load caused by sunlight
and by humidity removal� These factors must be
considered before selecting an air conditioning
system to provide year-round comfort� The Air
Conditioning Contractors of America (ACCA)
J Manual method of load calculation is one
recognized procedure for determining the heating
and cooling load�
After the proper equipment combination has
been selected, satisfying both sensible and
latent requirements, the system must be properly
installed� Only then can the unit provide the
comfort it was designed to provide�
There are several factors that installers must
consider�
• Outdoor unit location
