Frequently Asked Questions
R values are a way to assess how well thermal insulation works. An R-value is a measure of thermal resistance (i.e. how well it blocks heat) for materials, such as insulation, and assemblies of materials, like walls and floors.
The higher the value of R, the better the thermal performance and heat retention of the material or assembly.
These values are used in association with the insulation of flexible ducts, plenums and other airside components.
The Building Code of Australia (BCA) specifies minimum R-values required for different zones of Australia according to climate types.

Zoning is achieved by having motor-controlled "dampers" (a valve or plate that stops or regulates the flow of air inside a duct) situated within the ducts in your ceiling space.
Control of zones is accessed by using a third-party switch or via our range of Daikin Zone Controllers (i.e. featured on the NAV EASE Standard Controller and Zone Controller) that allows you to turn zones ON and OFF at will.
A common ducted system setup is one that has two areas specified as day and night zones. A "Day Zone" focuses on conditioning areas of your home that are occupied during the day (such as the living rooms) and a "Night Zone" on areas that are occupied more at night (such as bedrooms).
This two-zone setup ensures energy is not wasted by cooling or heating rooms that are not in use, and allows for more cost effective air conditioning of your home via a smaller capacity unit.
The key components of a ducted air conditioning system consist of a Daikin indoor and outdoor unit and a range of third-party airside accessories that help distribute conditioned air throughout a home.
These airside accessories include diffusers (from where air is released into the home), flexible ducts, return air grilles (which act as a filter to remove household dust) and motorised dampers for zoning capabilities.
The indoor unit is concealed out of sight, in your ceiling or under the floor, with flexible ducting distributing air through vents located throughout the home.
An outdoor unit is positioned in a discreet location outside the home. Our ducted indoor units are designed to be fitted into tight roof spaces, and the indoor unit can be separated into two sections making it light to carry and easier to manoeuvre through openings and in the ceilings.
A single phase air conditioner uses a single phase power supply, with single phase being the standard method of distribution of electric power in lighting and heating.
Three phase air conditioners require a three phase power supply and are generally used for models with larger heating/cooling capacity.
Three phase electric power is a common method of alternating current electric power generation, transmission, and distribution. It is the most common method used by electrical grids worldwide to transfer power and is used to power large motors and other heavy loads.
Choosing your air conditioner according to the requirements of a room or space rather than simply the power supply available is essential, and a Daikin Specialist Dealer will provide such guidance through an on-site consultation when you are selecting your Daikin system.
Flexible duct insulation is just as important as the performance of the air conditioning unit itself. It is designed specifically for flexible ducting systems and will ensure you keep your energy costs down and your air conditioning system running at its peak.
Ducts that are poorly sealed or insulated will result in heat loss from your branching network of ducts.
This decreases the cooling/heating efficiency of your home, which in turn contributes to higher energy bills.
Zone Control, available on all ducted systems, allows you to group specified rooms within a particular "zone".
This allows you to target within an established zone the specific rooms you want to heat or cool with your ducted system, rather than running your entire ducted system in the entire home or business.
Zoning can help maximise energy efficiency and comfort by specifically targeting heating and cooling.
For example, you may want to assign bedrooms to Zone One and the living areas to Zone Two etc., to thus enable these specific areas to be cooled or heated individually when needed.
When a zone is selected, cooling and heating will not be distributed to rooms outside the zone.
The position of the discharge grilles featured in a ducted system can also be tailored to suit the shape of each room within a zone, for optimum air circulation.
For Zone Control functionality your Daikin heat pump must be fitted with a Daikin Zone Controller and associated zone control dampers. The Zone Control is featured on the NAV EASE Standard Controller and Zone Controller.
Both are ceiling mounted systems, but fundamentally a bulkhead system is designed to provide air conditioning to a single room whereas a ducted system provides air conditioning to multiple rooms throughout a home or business.
A Daikin ducted system (such as the Premium Inverter, Standard Inverter and Slim-line series) is designed to provide flexible duct-distributed air conditioning in multiple rooms, with the indoor unit being installed in a ceiling space.
In comparison, a Daikin bulkhead system (such as the Inverter Bulkhead) is designed for single room air conditioning with a minimal duct run and is best suited for installation in drop ceilings.
