Applied Packaged Terminal Air Conditioners
and Heat Pumps are designed and built for through-the-
wall installation in either new or existing buildings. The

self-contained refrigerant system delivers cooling to the
desired space. Heating can be accomplished with electric
resistance, with hydronic (water or steam), hydronic
with intermediate electric resistance or with reverse
cycle technology (heat pump models only). Generally,
an estimate for capacity selection is 35 BTUH per square
foot of floor space (cooling) and 4 BTUH (1.25 watts)
per cubic foot (heating). The architect or engineer must
verify the selection. Note that the heat pump reverse
cycle generates approximately 10 BTUs per electrical
watt as compared to 3.4 BTUs per watt with resistance
electric heat. The unit will restart at its last setting after a
power interruption.
