Ducted Air Conditioning

Ducted air-conditioning has become highly sought after in modern times. By using ducted air-conditioning, you have the ability to use the same unit during winter and summer and they can be placed across ceilings or under the flooring.

The ducts are positioned strategically around your home or business and the cold or warm air circulates through those ducts, regulating as required to a comfortable temperature.

What size ducted air conditioning unit do I need?

The units vary in size and capacity. To ensure accuracy, measurements including area, number of stories in the home or office and dimensions are important prior to installation. This is engineered by our technicians and is called a heat/cool load calculation which is then presented as an individual duct work layout for your home or office.

It is important to choose the right system for your home or office. Issues sometimes arise when building plans change, for example when extensions and additional stories are added. This doubles the coverage area for ducts and the power cannot be sustained unless careful engineering and re-structuring/zoning options are further considered. We can assist you with this process if need be.

The equipment varies in size and power across several models. Accurate requirements need to be known in terms of area, the number of stories and dimensions. The plan for the duct system would then be designed and discussed accordingly.

How does the ducted air-conditioning system work?

During Summer, the hot air inside the room passes over a coil in the refrigeration system and transfers that heat to the internal chilled coil and therefore produces cool air into your home or office. The reverse cycle part of the system indicates that the system can change the flow of refrigerant and therefore create a heating output as opposed to a cooling output as desired.

A filtration system ensures that only clean air is circulated, therefore keeping your home dust and allergen free.

While such systems may be cost-effective, power bills escalate unless an inverter is used to control the compressor speed, Beyond Heating and Cooling only uses inverter technology to suit you home or office. Some structured planning helps focus the ducts on busy areas in the home or office, therefore achieving greater sustainability.

Reverse Cycle Ducted Refrigerated System

How does reverse cycle ducted air-conditioning work?

The reverse cycle system works on some basic properties. Essentially, the pump pushes heat from one location to another. To heat your home or office, a reverse-cycle system extracts heat from the outside air, even when it is very cold outside it is able to draw it inside.

Cold refrigerant, passes through an external coil, absorbing the heat from the outside air. This refrigerant is then pumped by a compressor (or pump), down through copper tubing and into a condenser. As the refrigerant is compressed, it warms up. The hot air that results is then pushed by a fan, out into the one or many rooms of your home or office, warming the area to a comfortable temperature.

Once this cycle is completed, the refrigerant flows through an evaporator to cool it down before being pumped back into the condenser and it then repeats’ the cycle again. When this cycle or process is reversed, cold air is then blown into your home instead of warm resulting in cooler air on hot summer days.

Add-on Cooling Systems

Evaporative Cooling

A vast range of evaporative cooling systems according to building size and number of rooms is available. Evaporative air coolers and evaporative systems will benefit homes and offices that are required to keep the installation and running costs to a minimum.

One of the advantages of evaporative air-conditioning is that the fresh outside air reaches indoors. When warm air is present in the rooms, doors and windows need to be left slightly ajar so that the warm air can escape outside when the cool air flows in through the ducts. Evaporative cooling units normally sit on the top of your home.  They are a popular choice for Victorians as they suit the moderately low humidity in the environment.

Evaporative systems also help to reduce dryness of skin, sore throats and skin sensitivities. Ducted evaporative cooling systems continually use outside air to cool the home, reducing the chances of these sensitivities. It also helps to ensure indoor plants will be kept energised and scents will be cleared away.

Evaporative Cooling Systems take away the complexity of refrigerants and coils. Ducts provide a passage for the cool / humidified air to circulate through the building. It contains a wetting medium that cools the external air and circulates the same through the building via ducts, evaporation results in the cooling of the air.

The system of ducts is usually located above the ceiling and it may not be necessary for every room to have ducts therefore keeping most of the energy for the busy areas.
