Installation of duct air conditioners

Duct type air conditioners are suitable for large houses, office buildings or public institutions, where it is necessary to regulate the air temperature in several rooms at once. Much less often such systems are installed in apartments, because their capacity is too large for small spaces.

Principle of operation and advantages

Air is heated and cooled with the help of duct devices by the same system as in other types of air conditioners:

1. Ducts connect the equipment to grilles that are located inside the room, where the air temperature is regulated.
2. Air from the room enters the grilles, then through the ducts reaches the heat exchanger of the indoor unit, where mass cooling takes place.
3. Freon heat exchanger of the outdoor unit gives off heat to the environment.
4. The cooled air is returned to the room.

Units of duct type are also used for space heating. They can be installed in several rooms at the same time. In this case, the installation of additional grilles in the network of air ducts or ventilation helps. To overcome the route from the external unit to the room, powerful fans are used.

Because of the last feature, the noise from the duct air conditioner seriously exceeds the similar indicator of other units. Therefore, it is recommended to install it in the part of the room where extraneous sounds will not disturb people.

The strengths of the channel type of units:

• the indoor unit is hidden, so the aesthetics of the room is not spoiled;
• fresh air from the street can be supplied through ventilation shafts;
• simultaneous service of several rooms with one device is available;
• air conditioner interacts with the ventilation system of the room, so the user can save on equipment.

Specialists of E-Engineering Co Ltd. recommend to install this type of equipment where the room area is from 100 square meters. Wall analogs will not be able to serve such space, so the cost of purchase and installation of channel air conditioners is more justified.

Types of duct type equipment

Masters of our company have experience in installation of any types of duct air conditioners:

1. Low-pressure. The air pressure does not exceed the mark of 45 Pa. The maximum length of the duct in this case is 50 centimeters. These are the simplest models available on the market. With their help, it will be possible to cool or warm only one room. To introduce them into the ventilation system to work in the whole shopping center is not reasonable. They are often purchased by hotel owners to maintain a comfortable temperature inside large rooms.
2. Medium pressure. The air pressure indicator increases up to 100 Pa. This type of split-systems is suitable for several rooms. It is often used in offices.
3. High-pressure. The value of air head rises up to 250 Pa. These are the most productive devices from the channel segment. They can be introduced into the ventilation system. Suitable equipment for large shopping centers, restaurants, offices.

It is also better to entrust the choice of climatic equipment to the professionals of E-Engineering Co. We will be able to draw up a full-fledged project of the air conditioning system, where calculations on the efficiency of the installed devices will be indicated.

It is impossible to install duct air conditioners without involving professionals. This procedure requires special knowledge in the field of creation of ventilation systems. Neglecting the opportunity to entrust the matter to reliable companies, you can doom yourself to a waste of money.
