How can I easily calculate the size of a
split system I need?
Here is a simple two-step formula you can
use:
1. Calculate the area of the room.
2. Multiply the area by 150 watts.
For example, if your room is 6 metres by 5
metres:
1. 6m X 5m = 30m square
2. 30m sq x 150 watts = 4500 watts (4.5kW)
Also useful to know which direction the room
is facing. There are factors that need to be
considered such as southerly facing rooms
require less cooling summer but more heating
in winter. If the room is facing west, or if
it is facing north and has large windows,
use a factor of 190 watts for your
calculation. In our example above, a
westerly facing room would need a 5.7kW
system. If more than two people occupy the
room in daylight hours, add an extra 200
watts for each additional person.
How often do I need to change filters?
The standard air clean filter uses static
electricity to clean dust and other fine
particles such as plant pollen that are too
small to see. Air conditioning filters
should be cleaned every three months and
ideally they should be cleaned monthly
during summer. You should also clean the air
vents at the same time. We recommend you
make a diary or calendar note at the start
of each year as a reminder.
What does "Back to Back" mean?
Back to back often refers to as straight out
and down. The indoor and outdoor units are
placed on opposite sides of the wall. This
reduces the amount of copper pipe run
required to connect the two units.
What is a split-system air conditioner?
The most common residential split-system air
conditioner is an air conditioning unit made
up of two units - an outside unit, the
compressor and an inside unit. A
split-system air conditioner can be used for
cooling and heating. |
