2.3 System Sizing and
Selection
Before specifying any heat pump equipment,
a survey of the structure and a heat loss and
heat gain calculation must be made. A heat loss
calculation involves identifying all surfaces and
openings that lose heat to the surrounding air
and quantifying that heat loss. A cooling heat

and 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 a heat pump system to
provide year-round comfort. The Air Conditioning
Contractors of America (ACCA) Manual J 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 system provide the
