Welcome to our guide on choosing a home air conditioning system.
With so many options, selecting the right air conditioning system for your home can be difficult. But don’t worry; we’ve got you covered.
In this guide, we’ll outline the different types of air conditioning systems available, highlight critical factors to consider when selecting, and provide tips for efficient operation.
Understanding the Different Types of Air Conditioning Systems Available
Several types of air conditioning systems are available, each with its own set of benefits and limitations.
The four main categories are split systems, multi-split systems, ducted systems, and portable units. Let’s have a look at each in more detail:
Split Systems:
A split-system air conditioner, as the name suggests, is characterised by its two distinct components: an internal unit and an external unit.
These two units are interconnected by utilising pipework and electrical cables, which facilitate the circulation of the cooling agent, commonly found in refrigeration products, between them. The external unit, being the more substantial and noisy of the two, is typically situated outdoors, while the lighter and more discreet internal unit can be positioned virtually anywhere within the building.
This configuration allows for a more aesthetically pleasing and unobtrusive installation. Modern split-system air conditioning designs offer the convenience of remote management, and many are now equipped with a heat pump feature.
This enables the system to function for both cooling and heating purposes throughout the year, ensuring maximum comfort and optimal room temperatures at all times. In addition, these advanced systems now incorporate integrated timers and an array of controls, allowing users to customise their experience with each use.
Split-system air conditioners are available in two main configurations: single-split systems and multi-split systems. A single-split system comprises one internal unit, while a multi-split air conditioning system features multiple internal units installed in separate rooms.
Multi-split systems are particularly well-suited for properties requiring air conditioning in multiple rooms or areas or residences across multiple storeys. This versatility and adaptability make split-system air conditioners an attractive option for various property types and sizes, providing efficient and effective climate control solutions for various needs.
Ducted Systems:
Ducted air conditioning systems are widely regarded as the most discreet and versatile cooling and heating solutions available.
With their ability to blend seamlessly into the background, these systems are ideally suited for various environments, including residential properties, open-plan offices, retail establishments, educational institutions, and eateries. They excel at providing consistent air distribution in large spaces where wall-mounted units might struggle to achieve even temperature control.
Installing ducted air conditioning systems is often the most efficient during the construction or refurbishment of a building. This allows for close collaboration between the air conditioning specialists and the architect or builder, ensuring that the ducted unit is expertly concealed within the ceiling void or above a suspended ceiling.
While retrofitting is possible, it is generally preferable to incorporate the system at the planning stage to avoid potential complications. It is crucial to note that ducted air conditioning systems typically operate in a binary on or off mode, which precludes individual control of each grille.
Consequently, these systems may not be the best option for environments with multiple rooms where occupants might require different temperature settings. To maintain the aesthetic appeal of ducted systems while accommodating individual temperature preferences, it is advisable to install multiple ducted units in the ceiling.
This solution allows each user to adjust the temperature settings in their respective rooms, thus avoiding any potential disputes over the ideal climate. Overall, ducted air conditioning systems offer an efficient, discreet, and aesthetically pleasing solution for maintaining a comfortable environment in larger spaces.
Portable Units:
Portable air conditioning systems, also known as free-standing air conditioners, offer a highly convenient cooling solution for various indoor spaces.
Equipped with castors at the base, these self-contained units can be easily manoeuvred and positioned according to one’s requirements, provided there is a nearby window and electrical socket. Their operation is similar to that of traditional air conditioners, with the primary objective being to cool the room’s air to a desired temperature by extracting heat and reintroducing the cooled air back into the space.
The fundamental components of a portable air conditioner include the evaporator coil and refrigerant, which are responsible for cooling the air; the condenser coil, which cools down the heated refrigerant; the compressor, which raises the refrigerant temperature for the condensation process; and the fan, which circulates the air as needed. In this process, the refrigerant plays a crucial role as a heat exchange medium, cooling the room air as it absorbs heat from the indoor environment.
Portable air conditioning units are designed to exhaust excess heat and moisture generated during the cooling process. The heat is typically expelled through an exhaust hose connected to a window or vent, ensuring that the warm air is directed outside the room.
In terms of moisture removal, portable air conditioners employ one of three methods: self-evaporation, gravity drain, or an internal receptacle. Most contemporary models utilise the self-evaporation method, which eliminates moisture along with warm air via the exhaust vent.
A distinguishing feature of portable air conditioning systems is their compact and stand-alone design, consolidating all processing units into a single apparatus. This design approach enables the most compact portable air conditioners to efficiently deliver cooling performance by clustering the refrigeration cycle components as closely as possible.
As a result, portable air conditioning units provide a versatile and adaptable cooling solution for various indoor settings, combining ease of use, mobility, and effective temperature regulation. When selecting an air conditioning system, consider factors such as your home’s size, layout, and insulation to make an informed decision.
Determine the Size of the Air Conditioning System You Need
