Air conditioning has become almost a necessity for ensuring comfortable living in a home. A decision of the type of air conditioner for the home or rooms in a home is often not an easy one to make. Air conditioners which are installed in windows and walls can be quite noisy, as the noise of the condenser and motors can be quite distracting. Quiet and peace can be ensured if a split unit is installed.

Split System Components

Split System units have two distinct parts. One is the main refrigeration unit consisting of the condensers and expansion valves, which are the noisy parts of the machine. The other part is the fan unit which ensures the distribution of the cooled air. The condensers in split units are installed outside the area to be cooled. The fan unit is installed in the living space and is linked to the condenser unit by refrigerant containing copper insulated pipes. These pipes pass through the fan unit and when air blows over them, the cooled air is distributed all around the area that needs to be cooled.

Factors Affecting KW Size

Once a homeowner decides that split units are the right ones for the home, the next question arises, which is, “What size of the split system do I need?”. It is best to approach the professionals for an answer to this question. They will consider the elevation of the house and the type of insulation that it has. They may also ask about the use of the room, as living areas generally require a higher capacity of units. The size of windows and doors, the number of access points, shade around the home, the orientation of rooms and other factors can also have an influence on the size of split unit that is required.

KW Measurement Guide

Air conditioner outputs are measured in kilowatts (kW). A 10 square meter room will need an output of 2.5kW. Every increase of 5 square meters will add a further 0.5kW. These are rough guidelines and can be influenced by the factors listed above. High ceilings and large windows can upset these calculations and they do need to be considered when you are trying to decide the size of the split system that you need. Split units have a higher capital cost when compared to window air conditioners, but they are quieter in operation and have higher efficiency. Split units can also remove moisture from rooms and are definitely the machines of choice for humid and coastal regions.

Other Factors

The size of a split unit can also be influenced by the number of people occupying any living area, and the presence of heat producing devices, like computers or kitchen appliances. Windows that face the sun can increase temperatures in a room and add to the required size of the split system. Most modern-day split unit systems have remote controls that allow temperatures also to be set.

Split units also save space in rooms and offer better light and ventilation, as window areas will not be blocked. The fan units are installed high on walls and rarely interfere with the decor. If you want to find out more about getting a split system for your Perth home, contact us today.
