1 - Ventilators

Equipped with a screw with a large or a smaller diameter, this device ventilates and refreshes the environment, without producing cold air.

Ventilators offer a good value for money and respond to a prompt need. There exist different models, to be used in different environments (at home, in common rooms, in offices,…).

The column ventilator: discrete and functional
This exceptionally practical column shaped model spreads a vertical air stream and rotates around 180°. It is perfect for refreshing a complete space in a lasting manner. This model is compact and silent.

A column ventilator can be moved and stored very easily. Thanks to the compact dimensions and the discrete finish, it is an ideal model for use in the office or at home.

Some models are equipped with a timer, a screen and a remote control. The functioning can be programmed in advance or at a distance.

2 - Choose a ventilator

The surface of the room, the dimensions of the device, the functions or the capacity,… There are several criteria that will influence your final choice.

Money for value
The first criterion that needs to be taken into account is the price. It is determined in function of the capacity and the available features, and it guarantees the quality and the origins of the device.

Capacity and air flow
The most important characteristic is the capacity of the device, that determines the amount of the circulated air. The capacity is expressed in watt (from 30 to 90 watt, depending on the model), and the air flow is expressed in m³/h or m³/min. For use at home, you can put the ventilator on a desk or on a table, with a low air flow (900 m³/h), while it is better to choose for a more powerful model with an air flow rate of 10 times higher, when it is necessary to refresh a complete room. In a professional context, the air flow must sometimes reach up to 18000 m³/h and you need to search for a model for large surfaces.

Diameter of the propellers
The ventilated surface is determined by the diameter of the propellers: the larger the propeller, the more efficient the ventilation will be, even from a distance.

Sound
Although few attention is paid in a garage or in a hangar to the presence of a ventilator, this criterion can be very important in an office or in a bedroom. The sound is measured in in decibels and it depends on the speed of the ventilator (the higher the position, the more sound it makes).

Multidirectional blowing
Most of the devices are nowadays equipped with this function, as it spreads the air stream over a large surface, without needing to move the device. Certain column ventilators can even rotate over 360°, in order to serve the complete room.

Speed levels
A ventilator is equipped with several speed levels, in order to adjust it to your needs. Watch out: the faster the ventilator rotates, the more sound it makes.

Programming, remote control and functions
Similar to a lot of other devices, ventilators are nowadays equipped with programmable functions (e.g. timer, delayed start and sleeping mode) and a remote control. When you manage the functions from a distance and you program the operating conditions, you can save a lot of energy. Several manufacturers offer new functions for a more comfortable use (functions for hot air or a breeze, with repellent effect against mosquitoes or with the distribution of an odor), or for a better health (distribution of essential oils or negative ions). Design
The design is particularly important when you want to install the ventilator in an office or in a living room. Efficiency and aesthetics go lately hand in hand, and the devices are often available in several colors, materials or shapes.

3 - Airconditioning

By absorbing hot air and pushing it outside, the airconditioner creates a comfortable cold feeling and it guarantees convenience and welfare, even when it is hot outside.

They are refreshing, they let the temperature drop down very fast, they renew the ambient air and they remove the humidity, in order to filter the air and to control the temperature according to needs.

Mobile airconditioners, for their functionality and simplicity
They are pretty voluminous, but at the same time really compact. As they are always equipped with wheels, it is very easy to move them from one room to another.

They are very practical for an occasional use and when it is not possible to execute large installation work, but they need an opening close to them, for the discharge duct. They can be used directly after purchase, by connecting them easily to a plug-socket of 230 V.

If you wish to buy a mobile airconditioning system, please contact us at MyBruneau or
on +32 (0)70 22 26 26.

Mobile monoblock airconditioners
Mobile monoblock airconditioners contain one single element, and they don’t need a special installation. They are one of the cheapest systems on the market.

This model absorbs the ambient air and dehumidifies it before blowing it again in the room. The hot air is discharged outside with a flexible pipe. The capacity is determined regarding the surface that needs to be ventilated: 2500 watt for a room of less than 50 m³ and 3500 watt for a room of more than 50 m³.

Mobile “split” airconditioners
These airconditioners contain a vaporizer, to cool down the room, and a condensator, to remove the heat. They function with a coolant, that circulates between the two parts. They combine the advantages of mobile devices and fixed models. They are more powerful, more budget-friendly and more silent than monoblocks. The opening you will need can also be a lot smaller.

Fixed airconditioning (or classic), for its capacity and its modesty
They are provided with one or more inner elements, for cooling, and with an external condensator, for removing the heat, linked to each other by a copper pipe with coolant. They offer higher performances than mobile devices, on the level of the capacity, as well as on the level of the volume and the sound.

Some models are also equipped with a heating function (these are called “reversible”) but they need a more difficult installation than mobile devices.

If you wish to buy a fixed airconditioner, please contact us at MyBruneau or
on +32 (0)70 22 26 26.

4 - Choose an airco

The airco is often the ideal device for tolerating extremely high temperatures. Welfare and comfort are guaranteed by its capacity to lower the room temperature, to dehumidify and to filter the air. Several parameters need to be taken into account when you are choosing the model that matches the best with your requirements and your budget.

Importance of the room’s characteristics and the habits of the users
The first criterion that needs to be respected is the place. Airconditioners, installed above doors, spread cold air that shall not disturb the employees.

It is also necessary to observe the architecture of the rooms. Surface, number of present persons, dimensions of the openings (windows or doors), quality of the isolation, orientation or climate,… All these elements can influence your choice.

A thermal balance can be essential, especially when you want to buy a fixed block.

The capacity
Once the characteristics of the room and the number of the involved persons are determined, the most suited capacity needs to be selected.

You need to calculate between 80 and 100 watt per m² (which corresponds with 30 to 40 watt per m³). The capacity is mostly expressed in BTU (British thermal unit). For information purposes, the next rules can be followed (1 watt = 3,414 BTU):

7 000 Btu is necessary for a surface of 7 to 15 m²
9 000 Btu is necessary for a surface of 15 to 25 m²
12 000 Btu is necessary for a surface of 25 to 35 m²
18 000 Btu is necessary for a surface of 35 to 50 m²
24 000 Btu is necessary for a surface of 50 to 70 m²
32 000 Btu is necessary for a surface of 70 to 80 m²

The higher the capacity, the more energy the device will consume. However, when the capacity is too low, the device will start to function in overdrive At the time of purchase, , please contact us at MyBruneau or
on +32 (0)70 22 26 26. The energy
Similar to most of the electrical devices, the airconditioners carry an enery label, that expresses their energy capacity (A for a maximal return, G for the least efficient types). Most recent models offer a lower energy consumption (class A or A+), for better performances. the EER (Energy efficiency rating), corresponds with the return in watt in cold mode (the delivered cooling energy is divided by the absorbed electrical energy); the COP (Coefficient of performance), determines the return in the heat pump mode (ratio between the recovered heat and the consumed energy), on a scale of 1 to 5. The higher the COP, the more the device will combine performance with energy consumption.
The air flow
The flow is adjustable and must be adapted to the dimensions of the room. A flow of 150 m³/hour is sufficient for a small surface, while 300 m³/hour will be necessary for a larger surface (around 30 m²).

But be careful: when the air flow is too powerful, it can generate too cold air streams.

The sound level
The sound level is normally situated between 30 and 70 decibels and varies depending on the capacity. The fixed airconditioners are the most silent models (the compressor is installed outside) with an average level of 35 decibels, while the monoblocks produce a sound between 45 and 60 decibels (comparable with the sound level of a fridge). Reversible, programmable or with other functions
Some models are also equipped with a heating mode, that allows you to reverse the functioning during a cold season and to enjoy an excellent supplementary heating system.

These are real 2-in-1 devices, which give you the opportunity to save a lot of money, even if they are more expensive at the purchase.

Certain devices function with a remote control, or it is sometimes possible to program the start, up to 24 hours in advance, in order to offer a maximum comfort.

At last, there exist also several models that combine different functions. These devices can be very interesting for persons with a lot of allergies or respiratory problems, as they function independently: they dehumidify the air without cooling it or they control only the humidity level. There are even models that can purify the air and remove bad odors.

5 - Air fresheners

Working principle
The air is absorbed and cooled down, and it goes through a humid filter, which is responsible for the vaporization.

For the best efficiency and a faster cooling, the water tank must be filled up generously and you can also add some ice bags.

Some models will even start to function automatically, as soon as the air humidity is too low.

Advantages
Air fresheners are a good alternative to ventilators and airconditioners, certainly because they are more ecological.

They offer a light and comfortable ventilation, without large temperature variations, and they procure more welfare and convenience, especially for sensible persons, as they are very versatile: ventilation, filtering, air humidity, and ionization of the air, depending on the model.

The air fresheners are easy to use and very mobile. You can move them hassle-free from one room to another.

These devices are perfect for rooms between 20 and 30 m² . Compared to other cooling systems, they cost less, which is very benificiary.

At last, you can save money, as they consume few energy (between 60 and 90 watt).

disadvantages
Functional and easy to use, but the air fresheners have also some disadvantages.

They are less efficient than ventilators or airconditioners when it is really hot, and they require a frequent ventilation of the room, in order to limit the humidity and to optimize the use.

Some models have a limited capacity, as they only vaporize hot air through a humid filter, and it is not possible to determine the ideal temperature, in contrast with other products.

The temperatures drop only with a couple of degrees and the air fresheners will only refresh people, who are sitting close by, and not the complete room. On the other hand, this limits the number of sick people, who caught a cold after large variations in the temperature.

Finally, it is important to clean the device frequently, in order to avoid the formation of bad odors or bacteria. You should also install it next to an opening, for a free air stream.
