Standard sizes of air conditioners: typical sizes of external and internal units

Purchasing and installing a fusion system today is not a luxury, but a necessity.This device comes in handy when the weather is too hot or cold. The air conditioner allows you to maintain the indoor microclimate at an optimal level. But the choice of fusion systems today is very large.

Do you agree that it’s hard to settle on a specific model among all those presented in the store? Few buyers take into account the standard dimensions for an air conditioner or pay attention to the dimensions of the device. The main purchasing criteria are usually appearance, brand, and price.

But the size of the air conditioner is important to consider when choosing. It depends on them whether it will be possible to place the device in the planned location of the room, as well as the installation features. A correctly sized and installed model will work as efficiently as possible. Therefore, it is important to understand what size an air conditioner should be.

We will tell you how the size of the internal and external units of a split system affects the operation of the equipment, for which rooms which size models are more suitable, as well as how and where it is better to locate the device. This will help you choose the best option and not be disappointed in the purchase.

Why do you need to know the dimensions of the air conditioner?

For those people who care about their health and well-being, it does not matter how much electricity the air conditioner consumes.

In order for the system to work effectively and maintain the temperature at the desired level, it is necessary to select the climate system taking into account its dimensions and power.

It is recommended to install split systems in bedrooms and offices. It has been proven that at temperatures above +26 and below +22 degrees, labor productivity decreases. This negatively affects the work rhythm and psyche. A correctly sized air conditioner will ensure the maintenance of an optimal microclimate in the room.

The size of the air conditioner is especially important for small rooms. Large systems in small rooms will look bulky and spoil the appearance. In addition, when installing them, serious difficulties may arise: the purchased device may not fit in the space allocated for it.

It is important to position the air conditioner correctly. From the ceiling you need to stand manufacturer's recommended distance. As a rule, it is in the range of 60-150 mm. The optimal distance from a perpendicular wall to the system is 400 mm.

If these requirements are ignored, the operating efficiency of the equipment will be low.

Recently, new approaches to the placement of air conditioners have appeared. Vertical indoor units of split systems are now available for sale. Such devices are equipped with a side outlet of cooled air.

Corner air conditioners do not look as bulky as rectangular ones and take up less space. Such models are the best option for small rooms.

It is important to choose an air conditioner of such a shape and size that it fits perfectly into the space intended for it and looks organically in the interior of the room. Also, the unit should not be too noisy.

The influence of air conditioner size on operation

Each air conditioner model has its own technical and operational characteristics. When choosing a device, it is important to pay attention to the dimensions of the indoor and outdoor units of the system. The performance of the equipment depends on this parameter. The larger the air conditioner, the higher these technical parameters will be, and vice versa.

The dimensions of the split system are determined by the dimensions of the parts installed in it. The larger the evaporator, condenser, compressor and other constituent elements, the greater the amount of air masses the device can process and produce per minute.

The productivity and power of the equipment determines how much area it can cool in normal operating mode.

Having selected several models of air conditioners in the store, you need to familiarize yourself with their power consumption and performance. Similar characteristics can be found in the device datasheet. This will help you decide on the best option for a split system.

Air conditioners that are compact in size are not always low-power. For example, some companies increase the performance of the device by installing more powerful fan. At the same time, the air conditioner becomes noisier when operating.

It is not recommended to install such equipment in the bedroom. Its constant noise will interfere with relaxation and proper rest.

Standard sizes of air conditioner

Split systems come in different types: domestic, semi-industrial and industrial. A wide range of this equipment makes it possible to choose the model that is optimal in size and design for any room.

One series from a particular manufacturer may include low, medium and high power air conditioners.Accordingly, their sizes will differ.

Standard indoor and outdoor units are rectangular in shape. The size of these units is characterized by three dimensions: width, height and depth. Home split systems are small in size. Industrial devices are more powerful, so their size is larger.

Indoor unit dimensions

Today, manufacturers produce air conditioners in different variations of the design of the indoor unit. This affects the length, width and height ratio of the device.

More often in apartments install split systems with rectangular internal module.

Rectangular air conditioners are very popular. Due to the fact that their shape is elongated, they do not look as bulky as square split systems. In addition, they can be placed above a window or doorway

The minimum dimensions of the internal unit of a split system are represented by the following values: height 24-25 cm, depth – 18-19 cm, width – 70-74 cm. Some companies produce wall-mounted air conditioners with an internal module depth of 18 cm. This significantly expands the possibilities for installing such equipment in different zones of a small room.

The width of the internal unit of a medium-power household air conditioner varies from 70 to 80 cm. Less common systems are up to 90 cm. The height is usually 25-29 cm. The average value is 27 cm, with a depth of 24 cm.

The maximum height of the wall-mounted indoor module is 30-32 cm, depth – 30 cm, and width – 110-120 cm.

If the indoor unit has a non-standard shape, for example, it is designed for vertical placement, then its dimensions will be different. The compact ceiling module is often made in a square shape.Its length and width are 50-100 cm.

Ceiling air conditioners evenly distribute air masses around the entire perimeter of the room. In this case, direct contact of air with a person is excluded. This reduces the risk of catching a cold. Ceiling air conditioners are also quiet. Therefore, such split systems are recommended to be installed in bedrooms.

For columnar blocks of split systems, which are mounted on the floor, the height reaches 100-150 cm. The width and depth are 70 and 80 cm, respectively. Due to such dimensions, column modules are not placed in small rooms.

If a device of different sizes from the standard is required, then most likely it will have to be made to order.

Outdoor unit dimensions

The dimensions of external air conditioner units are influenced by their design. The outdoor module can be square or rectangular. The largest parts of this unit are the radiator and compressor. Therefore, the larger they are, the larger and more powerful the device will be.

Split systems with a capacity of up to 2.7 kW have an external unit height of 42-60 cm. On average, this value is at the level of 50 cm. The width of a standard outdoor module varies between 66-80 cm.

The external block is usually placed 15 cm from the building wall. Taking this into account, the system protrudes approximately 42 cm from the cladding of the house

In medium-power air conditioners, this parameter is 70 cm. The depth of small outdoor units of split systems is 23-30 cm.

Higher performance devices have a larger external module. Its width can reach up to 86 cm, height – up to 65 cm, and depth – up to 32 cm.

Dimensions of mobile split systems

Popular mobile air conditioners. Their design is similar to wall-mounted options. They also consist of indoor and outdoor units. But their structure is slightly different.

The compressor is located in the indoor module. The external unit contains a fan and a condenser.

A mobile air conditioner is not capable of cooling a large area. It has compact dimensions and, accordingly, has low power. Therefore, such a device is usually installed in small rooms.

Both parts of the mobile split system are equipped with small wheels for easy transportation. The modules of such equipment are compact: their length is 50-70 cm.

Selecting the size of the air conditioner

To determine the size of the air conditioner, you need to think about where the device will be located. In this case, it is necessary to remember the rules for the distance of the system from the ceiling and walls. The equipment must have such dimensions as to fit well into the space allocated for it, without significantly reducing the usable free space and without deteriorating the overall appearance of the room.

Important choose an air conditioner, which will effectively cool or heat the room. If you install too weak equipment, then it will be of little use. Buying an overly powerful device will be a waste of money.

It is especially important to determine in advance the size of the air conditioner when renovating a room. Today, instead of painting and whitewashing the ceiling, they often install suspended structures. This can greatly affect the height of the room and the parameters of a suitable split system

To find out the optimal size of the air conditioner, you need to determine the service area. It is calculated by multiplying the length of the room by the width.

Manufacturers of split systems mark their products with various letters and numbers that indicate the characteristics of the equipment. For example, the marks “7”, “9”, “12”, “18”, “24”, “30” indicate the performance level of the device. Its dimensions depend on the cooling power of the air conditioner.

To understand what area the climate control equipment is designed for, you need to multiply the number printed on it by 3. So, if the device is planned to be installed in a room of 21-27 sq.m., then you need to give preference to “seven” or “nine”.

Such a split system has dimensions of 70x50x27 cm. If the room area is 27-36 sq.m., then you need to install an air conditioner, which is marked with the number “12”. Its dimensions are 75x52x29 cm.

In a room with an area of ​​42-54 sq.m. you should purchase an “eighteenth” air conditioner. Its dimensions are 80x54x30 cm. For large rooms, the area of ​​which reaches 72 sq.m., a device marked “24” is suitable. Its dimensions are as follows: 86x65x32 cm.

What if a standard air conditioner is not suitable?

Storerooms, dressing rooms, rooms with a non-standard layout require an individual approach to solving the issue of air conditioning the room. It can be problematic to place conventional wall-mounted split systems of the appropriate size and power.

A window air conditioner is small in size and does not reduce the area of ​​the room. It works quite quietly. The monoblock is a good replacement for the wall-mounted counterpart, but it worsens the appearance of the window

The way out of the situation is to purchase and install non-standard climate control equipment. For example, you can buy a ceiling air conditioner. This system is suitable even for very small rooms.

You can also purchase window air conditioner. It is a compact monoblock. The back side of such a device faces the outside of the window.

If you need to install climate control equipment in a large room, but do not want to spoil the appearance of the room, then you should choose a ducted air conditioner. This is a hidden type system. Only the grilles of this device will be visible in the room.
