*Air coverage represents the distance with one ft/sec air speed when blowing out
horizontally from the unit operating at the High fan speed. This is only a general
guideline; actual coverage depends on size and layout of the room.
M-SERIES AIR OUTLET COVERAGE RANGE*
It is very important that all contractors follow proper procedure and size
units based on a Manual J calculation. A load calculation takes into
account all the factors that cause the building to lose heat in the winter
and gain heat in the summer. Some of the factors taken into consideration
are exposed walls, insulation, windows, doors, and even the direction
the building faces.
INVERTER-driven technology has changed the way heat pumps are used.
Because the inverter can vary the capacity of the system, we can now
size units based on the largest load, which in many cases may be the
heat load. When single speed compressors are sized on heat load and
changed over to cooling, the units can be grossly over-sized. The result
is very little dehumidification and comfort problems.
Using charts like the ones below from the technical service manual, you
can check the equipment capacity at the design temperatures for heating
and cooling. If these values fall within both the heating and cooling
capacity ranges of the system, you can select that system
with confidence.
