Differences between split system and air conditioner briefly

Mobile air conditioner

The essence of mobile air conditioner is in its name. Mobile conditioner has no stationary position and can move not only within the limits of that room where it is established, it can be carried as well to other rooms. Such conditioner is located on the floor and most often has small wheels, so that it can be conveniently moved within the necessary limits. The most common models of mobile air conditioners have no outdoor units, so their installation and preparation for operation does not require the intervention of a specialist.

And nevertheless not to be just a fan, which pushes the air, but to cool it fully, the mobile conditioner has in its construction a flexible air duct with the length up to one and a half meter. It must be led outdoors through a vent, window or hole in the wall. Such air vent is needed to remove the hot air from the room that is being cooled. Just like a split-system, a mobile conditioner can easily fit in a modern interior, but you should remember that it is installed on the floor, and it means that it will take a certain space in your room, where the furniture could be.

One of the main advantages of mobile conditioner is its fast and comfortable moving to different parts of our apartment. Besides installation and mounting of a mobile conditioner is much easier than mounting of a wall-mounted split-system, because of lack of an outside unit (though in some powerful models a small outside unit can be present). Due to such simplicity mobile conditioner is also very easy to be transported in a case of moving. But their noise level can be not in favor of this type of conditioners, in fact while split-system works rather quietly, a mobile conditioner cannot be called as noiseless. Also the cost of modern mobile conditioners is rather high, if to compare them with popular split-systems again.

What are the advantages and disadvantages of inverter conditioner??

A buyer of air-conditioner willy-nilly has to understand technical peculiarities. What exactly the split-system is different from monoblock, is the fresh air moved through the tubes, is the plasma-purifier not dangerous? But one of the most frequent questions is what is an inverter??

Inverter air conditioners are able to regulate the capacity fluently. Ordinary air conditioner switches often on and off, but the split-system with inverter works constantly, changing capacity in dependence on conditions. The owner is not only spared from noise, but also saves up to 40% of electricity.

Inverter AC vs Normal AC

How to choose an air conditioner for your home: help to choose the criteria

Last summer we looked at choosing a home ventilator, a relatively simple household appliance that can significantly increase the comfort of being indoors in the summer.

Now it is time to deal with much more expensive and more complex (both technically and from the installation point of view) devices which allow fine-tuning the temperature in a premise.

It is worth to remember that most of conditioners do not provide inflow of fresh air (oxygen), but only keep constant temperature in a premise. Pluses and minuses of such devices are obvious: from one side the user can be sure that in a room will be exact temperature that he set at the conditioner. On the other hand, the risk of being in a stuffy (though comfortable by temperature) premise is increased. After all, an air conditioner can work properly only when the windows are closed.

Let’s see what kind of conditioners there are and how they are different.

Types of conditioners

Household air conditioners can be divided into several most common types, differing in installation method and, of course, in size. The main difference lies in the difference if our conditioner has an outside unit or not.

Air conditioners without an outside unit include monoblocks (permanently installed in a suitable place, such as a window opening or a niche in the wall) and mobile air conditioners, which can be moved when necessary.

Mobile air conditioners have a special pipe for the output of warm air, which should be mounted so that the air is led out of the window (in the package with such devices you can often find an adapter for mounting). As for the condensate, it evaporates naturally in most cases, but in some cases it may be necessary to remove it manually (draining the contents of the container).

Monoblocks and mobile air conditioners are usually used when it is not possible or not reasonable to install stationary air conditioner at the summer cottage, in a rented apartment, etc. п.

One specific type of a monoblock is a window conditioner, which is installed directly in a window or in a special opening in the wall. Exactly such conditioners were the most popular in the past, one can say, that with this construction boom of home air-conditioners began (mainly in the USA). However, nowadays they have essentially yielded their positions.

differences, split, system, conditioner

Window-mounted conditioner can be installed even by oneself (if a window and/or a premise in principle allows installing such devices). But here is the main catch: with appearance of double-glazed windows the installation of such conditioners is necessary to be calculated at the stage of measurements.

If one should take into consideration that window conditioners predictably lead to the heat loss in winter time because of low heat insulation between the inside and outside halves of the device, it is evident that such devices can be seldom met in those places, where double-glazed windows are installed and much more often, where wooden frames are used up to date.

Window conditioners are notable for their compact size, easiness of installation (and taking it apart) and their low price.

The next type is stationary conditioners (or split-systems). They consist of two blocks, one of which is situated inside the apartment and another one is outside. Such air conditioner is often equipped with air cleaning system, can work on heating and has a set of automatic modes. Both outer and inner blocks of such conditioners are well-known to everybody without exception.

Difference between Split AC & Window AC

There are some variants of split-systems, which differ by their functionality and the way of installation. So, multi-split-systems consist of one outer block and several inner ones, that allows to regulate independently the temperature level in each of the premise, where the inner block is installed (though all of them should work in one mode either for heating or cooling).

Ducted split-system is worked out specially for hidden installation and implies creation of a branched ventilation system (as a rule it is located above the false ceiling). Due to this, installation of one internal unit can provide the air regulation in several rooms at the same time (but in all the rooms the same temperature will be maintained). Such air conditioners often have an option of adding fresh air.

Finally, let us mention cassette conditioners. For installation of such system, as well as for a channel conditioner it is necessary to have a false ceiling. However, unlike duct-split-systems, cassette-type conditioners distribute cooled air through the lower part of the unit. Bottom part of the cassette split system has the size of standard ceiling tile 600×600 mm, and at high capacity twice as much as 1200×600 mm, and is closed by decorative grill with distribution louvers. Due to distribution of air streams along four directions this kind of split-system cools or heats air rather large premise quickly and evenly (as a rule such conditioners are used in the premises with the area from 50 square meters and more).

Inverter and ordinary models

Inverter air conditioner is equipped with a compressor with fluent capacity adjustment, which is provided with the help of inverter frequency converter. Nowadays, inverter air conditioners are available in the product line of every well-known manufacturer of climatic equipment.

Inverter air conditioners are advantageously distinguished by smooth regulation, low noise level, energy efficiency, ability to work on heating. At that invertor type conditioners are often more difficult to install and to repair and are more expensive than usual ones, that is why one should choose them more attentively.

Power and size of the room

In order to choose a proper conditioner before leaving for a store one should decide the size of a room and to find out its characteristics (the rooms situated on the sunny side of the house will need a stronger cooling system). Depending on it the power of air conditioner is chosen.

There is an informal rule, according to which for one square meter of a premise one should have 100 watt capacity of the conditioner (in this case we are speaking about the cooling capacity, but not about the consumed electric power). Thus, for example, conditioner with cold-productivity of 2-2,5 кW will cope with maintaining comfortable temperature in a room with the area up to 20 square meters (of course, on the condition that there are no additional heat sources).

In instruction to each conditioner one it is specified for the premise about which area it is calculated, but very often producer overstates this parameter, that is why by the fact one has to buy conditioner with extra capacity, or to study the reviews of users, who have already tried the model, interesting for you, in practice.

Also you should take into account that in reality conditioner cools not the area but the volume, that is why if your ceilings are much higher than 2.5-3 meters, you should correct the formula.

Noise Level

Noise level of a conditioner is rather important parameter. Especially if one intends to install a conditioner in a living room or in a bedroom. Monoblock or mobile conditioner will make more noise than split-system, because in that case compressor is situated inside the premise, while in split-system it is placed outside. Besides, in this case additional noise is created by air conditioner’s blowing system.

The maximum noise level of the air conditioner, as well as the power, is specified in the manual. But additional noise can appear because of undesirable vibrations and in particular it can be transferred on the floor (especially in case of wrong installation). In general and in this case it will be useful to get acquainted with the reviews of users: a big number of complaints to noise of some models makes you to think about the expediency of their purchase.


The simplest way of controlling the air conditioner is a mechanical control panel, which enables one of modes. For example, a fan-colder is strong/fan-colder is weak/fan is strong/fan is weak. It is clear that with such a control panel will not be too easy to set the most comfortable temperature in the room. And consequently one should think thoroughly before buying a conditioner with such primitive control.

The overwhelming majority of the models allow more precise setting, including precise temperature setting, timer, several modes of capacity, etc. п. Almost all serious models are equipped with a remote control. In our opinion, in this case one should not save money: it is better to purchase a device, allowing one to set a necessary mode as precisely as possible than to experiment with such conditioners, capable of operating only in several modes which can be unsuitable for the climatic conditions of the premise.

Availability of display on the inside of air conditioner unit allows finding out the current information on temperature, humidity, chosen mode, etc. п. It often happens when there is a display on the remote control, and it is undoubtedly very convenient.

Power consumption level

As many other household appliances, air conditioners have energy efficiency classes. In the 2010s, according to the new EEC Directive, the highest class A was divided into several subclasses: A, A and A, allowing to compare energy consumption of different appliances as accurately as possible. The calculation of these energy classes is done by comparing a certain standard energy consumption with the actual energy consumption, which allows to assign the device to one or another class quite accurately and thus clearly show the buyer which device will save on electricity, and which will be more energy-consuming.

Since the capacity of air conditioners can be very large, do not take the energy efficiency class lightly: with regular use over several years, a more efficient unit can save a round sum (which, of course, depends on the electricity tariff in your area). The most energy efficient by far is class A, which, by the way, is not very common, and appliances in this energy efficiency class will cost a lot more than their less economical brothers.

Also one should notice that monoblock and mobile conditioners will be almost always less effective than split-systems.

Extra functions

Household air conditioner can have many additional functions and features that simplify the operation of the device or increase the comfort of the user. Let’s list some of them.

  • Automatic temperature control. The air conditioner with such function can automatically maintain set temperature, switching from one mode to another (cooling, heating, ventilation) or changing the fan speed and air stream direction when necessary.
  • Auto restart. The automatic restart function allows the unit to automatically return to the previous operating mode after a power failure or the end of the operating cycle.
  • Motion sensor. Motion sensor allows switching automatically the device to an energy-saving mode at absence of motion in the premise, for example, if nobody is at home or at night when everybody sleeps. This feature will help to avoid overcooling or overheating and will save you money on your bills.
  • Air purification. In a standard conditioner it is possible to meet antidust and photocatalytic air filters. In addition to these, some models are equipped with additional filters designed to destroy bacteria and allergenic pollen. The residential series often includes four filters (two dust and two photocatalytic), which together are very effective against all known sources of pollutants. A special deodorizing filter will eliminate unpleasant odors (e.g., pets or food) and tobacco smoke from the air in the room.
  • night mode. After switching on this mode conditioner sets minimal fan speed (for noise decrease) and slowly decreases (when operating in cooling mode) or increases (when operating in heating mode) temperature by 2-3 degrees during several hours.
  • Adjustment of air stream direction. Models with such opportunity are equipped with special directing devices, which turn to the left-right and/or up-down, allowing directing air stream to a necessary side. Such function, for example, will not let you catch a cold if your workplace or a bed are located right under the air conditioner.
  • Dehumidifying air mode. This is an additional mode of operation, which removes excess moisture from the air. Can be useful in high humidity environments (e.g. rainy weather).
  • Supply of fresh air and humidifying. In air conditioners with this functionality, the external unit of the device takes the air from the street, cleans it and stores moisture, and then delivers fresh air into the house in the required volume. Besides, the air is humidified up to the most comfortable humidity level of 40%-60%.
  • Turbo mode. Makes it possible to quickly reach the set temperature. For this purpose conditioner works with high capacity, but not more than half an hour.
  • Wi-Fi support. Allows remote control of the conditioner with your smartphone.

So, let us repeat the main rules of choice of air conditioner for a house.

The first thing one should decide about is a type of a conditioner: will it be a monoblock or a mobile conditioner or a splitsystem? For an apartment it makes sense to pay attention on wall-split-systems. Such units are perfectly suited for different climatic conditions and temperature differences. And it makes sense to buy mobile air conditioners for summer residence or for installation in the premise, where is no possibility to install split-system with outer block. Cassette conditioners will be an excellent choice for the premises of 50 m or more² With a suspended ceiling. They are not used in small rooms.

Secondly you need to check whether the model you have chosen is suitable for your room. That is, make sure that the power of air conditioner is enough to maintain the desired temperature in the room with a certain area (for this purpose it will be useful to check the instruction manual of the device).

Thirdly you have to ascertain whether the control system of the device corresponds to your needs and allows you to adjust the required mode of work.

At last, before buying you should check whether the device supports the functions that you really need, and also you should specify the lifetime of filters.

When choosing a model of this or that model it is necessary to pay attention not only to the cooling area, but also to the energy efficiency of the system. One should not forget that conditioners, belonging to B class and lower will considerably increase electricity bills.

The difference between a split system and an air conditioner in short

Despite the fact that both varieties of climatic equipment perform the same functions, there are important differences between them. Split-system consists of external and internal components, and air conditioner consists of one unit.

Also there is a difference in mechanism of work. In split systems, the external component is installed under the windows from the outside of the building and performs the function of condensation. The unit consists of a fan, compressor and condensation system. Internal block is represented by an evaporator and a fan. Split-systems refer to the category of wall conditioners and do not place in one row with equipment, consisting of one unit.

Varieties of climate equipment

There are two types of equipment for air conditioning:

Monoblocks are easily mounted, adjusted and controlled. There are many quality models at the reasonable price on the market of climatic equipment. Monoblocks are installed in window frames or on the roof. There are mobile air conditioners with the possibility of transportation.

Split-systems consist of several blocks fixed on the external and internal sides of the building. Split-systems are more expensive than monoblock devices and need more time for installation. There are several varieties of split-systems. The most popular are devices of wall type, cassette type, mobile structures and recessed under the ceiling. If conditioner consists of several inner blocks, so it is referred to the category of multi-split-systems. Such equipment is installed in large rooms divided into several zones. Outer unit is led out to the street that’s why inside the building a working air conditioner doesn’t make a noise.

Types of Air Conditioners. Differences and Features

Air conditioners provide maintenance of comfortable for a man microclimate in the premises. Different types of air conditioners differ in shape, method of installation and maximum possible capacity and technologies used.

For air conditioner of domestic and small commercial premises you will be satisfied with mobile or wall-mounted conditioner.

For large commercial spaces. over 40 sq.m. The best choice with the bigger probability will be a half-industrial conditioner (column, ceiling, cassette or canal).

Roughly, for 10 square meters of premise 1 kW of cooling capacity of a conditioner is enough.

For example, for living room with area of 20 sq. m. air conditioner with power of 2 kW is suitable.

Split-systems. What is the difference between air conditioners?

Practically nothing. Split-system and air conditioner are equivalent notions. The peculiarity of split systems consists in their construction. two-unit design. This is their difference from mobile and window conditioners. To air conditioners, which are split-systems, we can refer:

For example: it is possible to call a wall-mounted conditioner as a split-system, but it is not possible to call a mobile conditioner as a split-system.

One of units of split-system is installed inside the serviced premise and has a wall-mounted version. It contains:

Another unit is placed outside the building and contains in its construction:

These blocks are united with each other by electrical wires and copper pipes through which the refrigerant circulates.

There is a branch pipe to the internal block, through which the condensate (more often by gravity, for this purpose the drainage pipe is fixed with a slope if there is no such an opportunity) comes out. A pump is installed, that forcibly pumps water through a pipe), condensate flows out into the street or in sewage system.

Complexity of communication connections and preparatory works requires attraction of only qualified specialists to installation of split-systems.

What is different between air conditioner and split-system

To create a pleasant coolness in the house in the warm season is successfully used climatic equipment. air conditioners and split-systems. The main task of such technique is to adjust the climate in the premise. Choosing equipment for your home or office, it is important to study some peculiarities of split-systems and air conditioners, because these devices have some differences.

What is the difference between split-systems and air conditioner?

Split-system. it is a kind of air conditioner. An air conditioner may consist of one unit (for example, a window or mobile) or 2 or more units. In the second case conditioner is called a split-system. split. separate), t.е. air conditioner, divided into inside unit and outside unit.

In window and mobile conditioner, compressor and all the rest parts are in one body, and as a result, these units are very noisy. Sometimes it is up to 50 dB, what can be compared to ordinary conversation of two people. It is almost unreal to sleep with such conditioner, there is no any silence. That is why it was decided to divide conditioner into 2 parts: one of them, the noisiest one, is set behind the window, and the second (the quietest). Inside of the premise itself.

Split-system can have one outer block and up to 8-9 inner ones, connected to outer block (multisystem or multisplit-system). Split-systems are divided into the following kinds, according to the type of an internal block:


  • Floor-to-ceiling (t.е. The indoor unit can be attached vertically to the wall or horizontally under the ceiling);
  • Cassette (t.е. that blow in 4 directions, square or rectangular);
  • Columnar (this is more for cafes, restaurants).

Type of indoor unit is chosen based on the specific task of the client. For the house, they usually take wall-mounted or ducted, for large rooms. cassette, column or floor-ceiling.

Some sincerely believe that the external unit is needed for the intake from the street. It’s a myth. Actually, the air is taken in by the indoor unit, cooled and discharged back out. Once again we should repeat that the noisiest parts are hidden in the external unit. The outdoor unit itself is outside the room and does not cause any discomfort to the user.

However, there are models that can take in air from the street, purify it, cool it and release it into the room. for such air conditioners can reach 130-150 thousand. rubles.
