Multi-Head / Split System Heat Pumps / Air Conditioners

A multi split system heat pump / air conditioner offers more flexibility and performance than a single room system. Multi split heat pump / air conditioning units consist of up to six indoor units that distribute cool air throughout the space: and an outdoor unit that draws heat out of the room. Reverse cycle systems can invert this operation, offering the ability to expel a chill from the space and replace it with warm conditioned air.

A split system heat pump / air conditioner works by distributing gas into the compressor, located in the outdoor unit. The compressor pressurises and heats the gas, before sending it through condenser tubes which convert it into a hot liquid. The indoor unit uses the change in temperature to cool the air that has been sucked from the room, which is then released back into the space as clean, cool air.

Multi split system heat pump / air conditioners are a flexible, efficient and effective method of heating or cooling your home. They provide numerous benefits over single room and even ducted heat pump / air conditioning solutions, including:

• Simple installation: Multi-split system heat pumps / air conditioners do not require ducts for installation, lowering the cost and complexity of installation. 

• Cost effectiveness: A multi room heat pump / air conditioner is a cost effective way of heating or cooling multiple rooms in your home, when compared to purchasing a number of single room units or a ducted system. 

• Easy to maintain: While a multi split heat pump / air conditioner will still require periodic maintenance, not having to service ductwork or multiple outdoor units reduces the costs of servicing your system professionally.

• Quiet operation: Many modern units, including those offered by Fujitsu General, feature quiet operating modes, making them ideal for bedrooms or home offices where low levels of noise are necessary.

A multi system is most effective when it comes to providing efficient heating and cooling solutions for multiple rooms or areas in a residential property. This is particularly true for larger homes where installing single room heat pumps / air conditioners may not be sufficient.

With a multi heat pump / air conditioner, you can have multiple indoor units connected to a single outdoor unit, allowing you to control the temperature in different rooms independently. This means that each room can be set to a temperature that suits the occupants, without having to heat or cool the entire house to the same temperature.

A multi heat pump / air conditioner is also more energy-efficient than running multiple single systems as it requires only one outdoor unit to operate multiple indoor units. This can help reduce your power consumption, which may lower your energy bills.

The main difference between multi split systems and ducted heat pumps / air conditioners is in the way they distribute conditioned air throughout a building.

Multi split systems typically consist of an outdoor unit and two or more indoor units that are mounted on a wall, floor or ceiling in the rooms they are intended to cool or heat. These indoor units blow conditioned air directly into the room, and each unit can be individually controlled to provide custom temperature settings in different areas of the building.

On the other hand, a ducted system uses a central unit to distribute air through a network of ducts installed in the walls, floor or ceiling of a building. The conditioned air is then delivered through vents or grilles located in each room. Ducted systems are often preferred for larger homes or commercial buildings as they are able to provide consistent temperatures throughout the entire space.

Another key difference between these systems is in their installation requirements. Multi split systems are typically easier and less expensive to install than ducted systems, as they do not require ductwork. However, it is important to note that multi heat pumps / air conditioning systems may not be ideal for larger buildings or spaces where a ducted system would be more efficient.

The number of rooms that a multi room heat pump / air conditioner can serve depends on the specific model and capacity of the heat pump. However, multi room heat pumps / air conditioners are designed to provide efficient heating and cooling solutions for multiple rooms or areas in a residential property.

Typically, a multi room heat pump / air conditioner system consists of one outdoor unit that is connected to multiple indoor units installed in different rooms or areas of the building. The capacity of the outdoor unit will depend on the number and size of the indoor units that it is connected to.

In general, a single outdoor unit can serve up to six indoor units, but this will vary depending on the model and capacity of the heat pump / air conditioner. For larger homes or buildings, multiple outdoor units can be installed to serve a greater number of indoor units.

Modern multi split heat pumps / air conditioners are equipped with a number of features to make them more efficient and tailored to your individual needs. If you are looking at installing a heat pump in multiple zones throughout your home, there are a number of functionalities you should consider to help you choose the right unit:

• Timers: Many split system heat pump / air conditioners allow you to program their operation using a weekly timer. Some systems are also equipped with a specific Sleep Timer that adjusts the temperature and fan speed throughout the night to ensure a comfortable night’s sleep.

• Filters to improve air quality: A multi room heat pump / air conditioner with an inbuilt filter that purifies the air inside the room as it operates can be an excellent way of reducing the amount of pollutants in the air. These systems can be particularly handy for allergy sufferers. Many Fujitsu General models are equipped with an Apple-Catechin filter that eliminates mould spores and other allergens.

• Economy mode: Multi room air conditioners that include economy mode as a feature can help reduce your energy bills, optimising the use of the unit to provide a comfortable temperature whilst drawing less power from the compressor.

• Adjustable fan speeds: For instances in which a sudden change in the amount of air being distributed is necessary, a multi split heat pump / air conditioner with adjustable fan speeds is both convenient and efficient.

• Quiet operation: A quiet indoor unit operating mode, such as the Super Quiet Mode functionality of some of Fujtisu General’s multi room heat pumps / air conditioners, helps to lower the amount of noise emitted by the air conditioner, reducing distractions in bedrooms and study spaces.

Yes, multi room residential heat pumps / air conditioners are generally considered to be energy-efficient, especially when compared to traditional heating and cooling systems.

One of the reasons for their energy efficiency is that they use inverter technology, which adjusts the compressor speed to meet the heating or cooling demand of each room. This means that multi systems only use the amount of energy needed to maintain the desired temperature, reducing energy consumption and resulting in lower energy bills.

Multi room heat pumps / air conditioners also allow for different areas of the home to be heated or cooled, which means that different rooms can be set to different temperatures based on their individual requirements. This eliminates the need to heat or cool the entire home to the same temperature, which can waste energy and lead to higher energy bills.
