Multi split air conditioner buying guide

There is a wide range of solutions to cool off in the summer. One of the best alternatives is Multi Split Air Conditioner which has many advantages. The market is flooded with countless models of multi split air conditioners. Brands compete in imagination to stay one step ahead of the competition. To be sure that you have an air conditioner capable of meeting your needs, it is recommended that you make your choice with the utmost care. In the following article, you will find practical tips and selection criteria that will help you see more clearly.

What is a multi split air conditioner?

As opposed to packaged air conditioners, split models are made up of two distinct units:hot air extraction unit which is placed inside and theevacuation unit which houses the motor located on the outside.

In the family of Split air conditioners, we distinguish the mono split and the multi split. The former have only one internal extraction unit for an external unit, while the latter offer the possibility of connecting several internal units with the single external unit.

The multi-split air conditioner is therefore recommended to cool 2 to 5 rooms independently. It makes less noise than a one-piece version since the motor is placed in the outdoor unit. A sound level test can be performed to determine the best product on the market. On the other hand, it is more complex to install since it requires a large number of branching and piping connections.

The indoor units each have a display screen and an independent control panel for setting them to different temperatures. This is an excellent point especially when you have rooms of different sizes to be conditioned.

The main difference between multi splits is not technical, but rather aesthetic. The ergonomic design and the format of the models available on the market will already determine your final choice.

We can therefore find recessed wall units, fixed wall consoles, ceiling lights or consoles or cassettes suspended from the ceiling. You just need to buy the model that best fits your interior design. A comparison table is essential to compare the different technical characteristics.

It is important to distinguish, however, reversible multi split air conditioners where the 2 in 1 multi split air conditioners. They act both as heating when it is cold and as cooling when it is hot.

The best multi split air conditioners are equipped with Inverter technology. It allows automatic regulation of the power of the device so that the air temperature aligns with that of the surrounding environment.

Finally, the multi split 3 in 1 are very trendy, because they not only allow you to switch from ventilation mode to the heating mode where the humidification mode. Very versatile, they are recommended to have a little heat in winter, coolness in summer and a not too dry atmosphere.

How much power do you need?

The power of a multi split air conditioner depends entirely on the size of the room (s) you wish to equip. To help you better choose a model among the best multi split air conditioners of this comparison, here is a small power guide.

For a room of up to 20 m², you can use a 2 to 2.5 kW multi split air conditioner. From 20 to 40 m², your choice should be a device of 2.5 to 5 kW. For an area of ??40 to 60 m², the ideal is to opt for a power between 4 and 6 kW. Between 60 and 80 m², it is recommended to use a 5 to 7 kW multi-split air conditioner. And beyond 80 m², you need power, ie between 6 to 9 kW.

This is only a rough guide. But, it is recommended to do the math yourself to have more precision on the real power required.

If you use a multi-split air conditioner that is too powerful for the size of the room, the unit may cycle short, but frequently to reach the target temperature. This can cause several problems:

  • too much or too much of a rise in temperature
  • inadequate dehumidification (the air is not dry enough, which makes the room less comfortable)
  • an increase in electricity consumption
  • high operating costs
  • premature wear of the air conditioner

If you install a low-power air conditioner, on the other hand, the unit could run at full power constantly, which could overdry the air and cause rapid wear and tear on the system.

In this sense, if you do the math and you get for example 6 kW for the room, the ideal is to look for a multi-split air conditioner with a nominal power between 6 kW and 6.5 kW. This is the safest way to get a suitable model or slightly above the horsepower required for the part. You can add a few Watts to get cooler temperatures faster during hot weather. But do not exceed the required power too much.

How to calculate the power of a multi split air conditioner?

You can find online tools which allow you to make an approximate calculation of the useful power for air conditioning the rooms where you want to install your multi split air conditioner. As a result, they can come up with a wattage that is above what you actually need.

Indeed, there are many variables to take into account. For example, a room with good insulation and openings facing east or southeast will require more power than a calculator provides as an answer. Conversely, a poorly insulated room with openings facing south will require less power than the tool offers.

In other words, to make a correct calculation, consider the following points:

A correct calculation takes into account all the details of the part:

  • The volume of the room: length, width and height
  • The type of room: living room, dining room, kitchen, bedroom, etc.
  • The orientation of the glass openings: a bay window facing north or west
  • A large window facing south or southeast can let in a lot of heat in the summer.

  • Shutters and curtains on the windows
  • Insulation of the floor, ceiling and walls
  • The climate in the region

How to choose a multi split air conditioner?

Power

The best multi-split air conditioners on the market have high cooling and heating power (over 5 kW). By using a comparison table, it is possible to identify the most powerful models. It is better to have a sufficiently powerful device on a device with 5 internal units. The cassette air conditioner is by far the most powerful if you take a comparison.

Installation

The choice of location is essential, but it is also necessary to study the configuration of the premises before considering the installation. The length of the sheathed pipes actually depends on this preliminary study. In addition, the handling of refrigerants requires the intervention of a specialist professional. Note that there are multi split air conditioners compact and very aesthetic which are not very bulky despite their price a little higher than the average. You should also know that some models have restrictive installation conditions such as the wall version which must not be placed less than 2 meters from the ground. The units must not be hidden behind a piece of furniture, for example, because in order to be able to clean them regularly (mandatory), the device must be easily accessible.

Energy performance

Do you want a quality multi split? Do not neglect this parameter, which allows you to categorize your device during the energy audit of your home. The energy performance test can be essential to be sure of the consumption of the device. On average, a good multi-split air conditioner that operates all year round consumes around 250 kWh per year in cooling mode and up to 1300 kWh per year if it needs to distribute hot air.

Operating modes

Some multi-split air conditioners have different operating modes to suit the needs of its user. It would be advantageous for you to have them on the model you have chosen.

  • Auto: the device itself chooses the mode appropriate to the room to maintain the temperature at the right level.
  • Cool : the air conditioner directs indoor heat to the outside to cool the room.
  • Heat: the air conditioner captures heat from the outside and transfers it inside, like the principle of a heat pump, which makes it possible to heat the room.
  • Dry: this mode dehumidifies the air.
  • Fan (fan only): the air conditioner sends forced air into the room without heating or cooling it.
  • Economy: this mode reduces electricity consumption. But it depends on the brand. Indeed, it can either simply reduce the fan's output or adjust the thermostat a few degrees, or detect the presence of a person in the room to regulate the temperature.

Motion detector or human presence sensor

This feature is very convenient. And as mentioned before, it is used for the mode Economy. The sensor detects the presence of someone in the room and turns on, off or regulates the temperature level accordingly.

Some models have a motion detector and are able to direct the flow of air to the detected person. If no person is detected, the device switches to Economy to consume less energy.

However, even if your multi-split air conditioner is equipped with a sensor or motion detector, you should not leave it running all the time. If you are away, turn it off and activate the timer function to turn it back on before you get home.

Remote control

Many multi-split air conditioner manufacturers (Mitsubishi Electric, Daikin, Bosch?) Offer models that can connect to your home wireless network. Thus, through an application on your Smartphone, you can control your air conditioner remotely using an Internet connection. This is a handy feature when you are at work and want to heat or cool a room in your home before you enter your home.

Besides, this Wifi function could be integrated in the air conditioner or not, depending on the model. You may need to purchase a controller that you add to your multi-split air conditioner to be able to activate it remotely.

Air filters and self-cleaning function

Today, multi split air conditioners have the best filtration devices. They can filter dust, odor, allergens as well as mold from the air.

And to simplify the task for the user, they are most often accompanied by a self-cleaning function. It allows the indoor unit (diffuser) to be clean to function optimally at all times. It is clean, reduces dust build-up and prevents mold growth if the dehumidification function is not fully operational.

Adjustable or oscillating louvers

The diffusers of most multi split air conditioners are adjustable and can swing up and down. This is convenient as it is recommended to point the louvers up to cool the temperature and down to warm it. Using the device's remote control, you can do this from a distance.

Restart delay

A multi split air conditioner with a restart delay is a good device. This function preserves the correct operation of the compressor. If the outdoor unit or condenser restarts too quickly, it may cause damage.

Operating range

Knowing the operating range can help you choose the right model for the climate in the area where you live. The majority of multi-split air conditioners operate at varying temperatures from -10 ° C to 45 ° C.

Automatic defrost

During winter, if the temperatures drop to -15 ° C, it is important that the multi-split air conditioner you have chosen has the automatic defrost function. This allows the outdoor unit to quickly remove the frost that has formed on the heat exchanger coils.

Refrigerant type

Refrigerants (eg: chlorofluorocarbons or CFCs) that affect the ozone layer have been withdrawn from the market. But on multi-split air conditioners, it has been replaced by hydrofluorocarbon or HFC. And although this refrigerant was the subject of a new international agreement in 2016, only variants are currently used on these devices. HFC R32 is the most common, but there is a trend towards HFC R410A, always for ecological reasons.
