Countermeasures
(Reference)
When the
ceiling is high
If the indoor unit is installed where the installation height
given in the installation manual is exceeded, the temperature
difference between the floor and ceiling of the room will be
large and the heating effect will be poor.
Moreover, even if the indoor unit is installed within the
installation height, a similar phenomena will occur when
installed in a room in which the doors are opened and closed
frequently and hot air circulation is obstructed by desks, chairs,
etc.
(1) Switch the setting to the high
ceiling mode.
(2) Install a circulator.
(3) Arrange the furniture in the
room so that it does not
obstruct the hot air.
When lower level
directly contacts
the outside air.
When the lower level of the shop and office is a warehouse,
parking lot, etc., the surface temperature of the flooring
will become low and the radiation of cold from the floor will
increase.
In this case, your feet will feel cold even if the room
temperature is suitable.
When the air
flow distribution
is poor
When an indoor unit is installed in a position where the outlet
air flow will directly contact people, a draft may be felt.
In addition, when there are obstructions in the path of the
intake and outlet air flow, the air distribution may become
extremely bad.
(1) Adjust the louver fins or take
other measures matched to
the site.
(2)Change the indoor unit outlet.
