A multi split unit is the same basic technology as the single split air conditioning system however it allows the user to connect more than one indoor unit to the outdoor unit. One of the key benefits of this approach is reducing the number of outdoor units required for a multiple indoor unit installation. The indoor units need not be the same type, this flexibility allows for different indoor unit options for different rooms within the same house.  The units are linked by a set of refrigerant pipes and some cabling. Systems are available in a cooling only or heating and cooling options.

 

 

Indoor Unit Options and Combinations


There are a number of alternative indoor unit options available, the choice of which will depend on the unit’s interaction with the proposed space and your preference. Note that in all instances the overall system configuration remains the same (for example; indoor units, outdoor unit and refrigerant piping), with only the indoor unit changing in each case. Work with us to find the indoor unit that works for your space!

Wall Mounted

Wall mounted air conditioning units are among the most commonly installed domestic air conditioning system. Their installation is low on impact, cost and space with a functionality that is familiar.

They are a great option for both new builds and for the addition of air conditioning to an existing space.

Concealed Ducted Unit

This ducted air conditioning option affords the user the opportunity to conceal the indoor unit behind suitably aesthetic ventilation grilles. It is an excellent option when a discreet air conditioning installation is preferred. Units are typically installed above lowered ceilings, delivering the air to the space via a bulkhead. This iteration is a single zone unit.

Concealing the air conditioning unit ensures that it is out of sight and out of mind.

Multi-Zone Ducted Unit

Again this option affords the user the opportunity to conceal the indoor unit behind suitably aesthetic ventilation grilles. In this case the unit supplies and returns air from multiple spaces and is installed in a central location. This unit gives more flexibility on the type of ventilation grille that may be used, introducing grilles that may be installed flush to the ceiling.

Concealing the air conditioning unit ensures that it is out of sight and out of mind.

Ceiling Mounted (Cassette)

Although less common in a domestic setting the ceiling mounted ‘cassette’ type air conditioner offers great functionality in a space, allowing for a centrally located installation and 360 degree air distribution.

Ceiling mounted units can be an excellent choice in a dining or multi-functional room setting domestically and commercially their air distribution is the perfect pattern for an office environment.

Floor Mounted

Floor mounted units come with both a standard and a concealed option.

The standard model is low impact from an installation perspective and offers a sleek design. There are options to mount them to both wall and floor.

Floor Mounted (Concealed)

A concealed floor mounted AC unit is a great option for areas where ceiling and wall space is at a premium.

They can be recessed within walls or housed within custom joinery with only their two grilles and the controller visible.

A concealed unit is out of sight and out of mind.

Under Ceiling Suspended Type

Again less common than the wall, floor and ducted units the ceiling suspended offers an alternative where spatial or design considerations prohibit the use of the other indoor units.

It’s main operational benefit is an excellent air distribution pattern via the high level supply.

Multi Split Characteristics


 

High efficiency inverter technology

Modern air conditioning systems benefit from advances in inverter technology. This allows the unit to deliver the required room conditions in an efficient, economical manner. This saves money on running costs and reduces our environmental impact.

 

Single zone control

Multi Spilt systems comprise multiple indoor units, each serving a single zone, allowing the occupant to switch on or off the unit as and when it is required without affecting other occupants in the house. The unit may also turn on and off based on a number of other methods, including an occupancy sensor, preferred set point conditions or via a time schedule. This ensures that energy is not wasted conditioning unused spaces. In a multi system control from a central controller is available, allowing for all of the above settings to be programmed universally or individually.

 

Additional control options

From the wall mounted or remote controller with the zone the occupant can easily switch between the available modes; heating, cooling and ventilation while adjusting the immediate perceived effect of the supplied air via the fan speed, air direction and room temperature. WiFi connectivity of the systems is available, allowing you to remotely operate your systems. This ensures that you can come home to an environment that suits you.

 

Low noise

Modern units are quiet thanks to efficient fans and a focus on effective noise control. The unit can operate in the background without affecting your focus.

 

Cost effective

A multi split offers clear economical benefits when compared to multiple single split systems; combining what would be multiple compressors, condensers and runs of pipes to single iterations.

 

Ease of installation

As above, when compared to multiple single split installations, the multi split system offers clear benefits; not least of all a reduced outdoor unit impact.
