What
you should know about wall mounted split type air conditioning |
| Position
of indoor unit |
This
should always be mounted at "high level" due to the design of
the unit, mounting at low level will result in drafts and uncomfortable
conditions. |
| Selecting
the wall |
The
perfect wall is an outside wall and preferably the same wall can be used
for mounting the outdoor unit.. The advantages to this are several, (1)
The 60mm hole for the pipes and services to the outdoor unit can be "hidden"
behind the indoor unit. (2) The condense water in summer cooling can gravity
directly to a suitable rainwater drain outside. (3) The pipe separation
is shorter which means cheaper and quicker to install, (4) The system will
perform better. |
| Can
my outdoor unit go higher ? |
Yes
! The outdoor unit can go higher or lower than the indoor unit but there
are limits. For example If you have a manufacturers allowable horizontal
of 15 mtr pipe difference and the outdoor unit is to be sited 5 mtrs lower
or higher, then this 5 mtrs must be deducted from the allowable horizontal
separation making the horizontal distance 10 mtrs. Most small split units
maximum "lift" is 5 mtrs. |
| I
have no outside wall ! |
It
can usually be overcome, An example is a high wall mounted unit where the
pipes go up into the loft, they go over three rooms and eventually exit
at the rear of the house where the outdoor unit is mounted on wall brackets,
One problem is the condense water, as water will not flow uphill a lift
pump is needed to suck the condense water into the loft space, the pump
then forces the water to any suitable drain. There are lots of other ways
around installing without a direct outside wall, but it is usually the condense
water that is aggravation. |
