best air conditioner

Mobile air conditioners are relatively quick and easy to set up due to external product testing, field tests, and studies. Compared to a fix-mounted air conditioner, they can be transported from room to room and gradually provide pleasant temperatures. This is a practical advantage compared to built-in air conditioners.

But if the wrong air conditioner is chosen, the cooling pleasure stops right there. Often cheap devices do not achieve the effect with the required needs. There is also the power consumption – air conditioners can become a true cost burden.

According to an analysis, users use an air-conditioning system to reduce humidity in rooms and to filter room air. Air conditioning units do not only create pleasant temperatures during summertime. According to a scientific survey, various models can also be used in winter to improve the air quality a little.

Anyone who decides after an in-depth inspection for an air conditioner, according to the external of a study, should most definitely take a look at the individual properties and especially on the energy consumption. Highly recommended is a purchase after a successful personal aptitude test! Use independent comparison tables for decision-making!

Independent product reviews and experience of other consumers on the Internet can be helpful. Besides, you can get information about the air conditioner from salespeople or independent comparison charts to find your winner. In regards to power consumption and cooling capacity, however, other aspects play an important role.

Mobile air conditioners should not be too loud and should offer heating services if possible. In terms of noise volume, an air conditioner is comparable to a hairdryer. Do a test in a store before purchase and decide for yourself which features you want or not.

Beware to not fall for any unnecessary features which will always increase the price. Decide for yourself what you need at home and what extras you can live without.

How Does An Air-Conditioner Work?

You can compare the operation of an air conditioner with those of a freezer in a fridge. It should be noted at this point, however, that the performance of an air conditioner is many times higher.

Besides, there are complex, mobile air conditioners that consist of both an inner and an outer part.

For air conditioning units and their functions, you must always differentiate and compare between two model types.

Following experiments, product tests, field tests, examinations, and proficiency tests, there are many types with a good energy efficiency rating that not only cool and but also heat the air. An included heating function has the advantage that the indoor air can be dehumidified at the same time. Compare and test both types to balance your needs.

  • The circuit of an air conditioner is hermetically sealed off. The circulating refrigerant is the core of the cooling process.
  • The gaseous refrigerant is sucked in by the compressor in a first step. The refrigerant is compressed so that it reaches very high temperatures.
  • The refrigerant is still gaseous but very hot. It is pumped from the compressor to the so-called condenser.
  • The refrigerant now receives a cooling from the condenser. The state of aggregation finally changes from gaseous to liquid.
  • The refrigerant is now liquid, but under enormous pressure. Therefore, it is returned utilizing an expansion valve in the condenser.
  • There, the device takes care of the actual cooling process. As a result, the liquid refrigerant starts to evaporate.
  • The heat that is necessary for this is extracted from the room air. The fan draws in the warm air, blows it into the evaporator and releases the cooled air.
  • The gaseous refrigerant returns to the hermetic circuit and the cooled air is returned to the room.
  • Since the circuit of an air conditioner is sealed airtight, no refrigerant is lost during the cooling processes.
  • However, water vapor condenses from the air in the condenser. A condensate tray catches the liquid. Therefore, pay attention to empty of the tray regularly.

What Types of Air-Conditioner Exist?

There are very different types which differ in application areas, services, and energy efficiency class.

Monoblock Air-Conditioner

A monoblock airconditioner is easy to use and consist of a body and a hose to exhaust air.

This exhaust hose transports the heat, which was taken from the room air, into the open air. Most of the exhaust hose goes through a window or a door.

In most cases, the hose is between 1-2 meters long. Therefore, the installation options are limited. Monoblocks are therefore only suitable for rooms that have up to 20 square meters. Otherwise, their performance is rather ineffective.

Only in small rooms, the desired cooling of the room air is achieved. Also, the rooms should not be exposed to direct sunlight. Otherwise, the performance of a monoblock is drastically reduced.

Generally, monoblocks generate far more noise than other air conditioners. Here, 45 to 55 dB can be assumed. This is about the volume of running music radio.

In addition, it creates an unpleasant situation as hot air blows in the room by the door or the window while trying to cool down the room.

Portable Air-Conditioner

These air conditioners units are installed either on the windows or wall but are not as easy as monoblocks.

Compact air conditioners also consist of a carcass from which the warm air is transported outside and cooled air into the room.

The compact air conditioners are on a similar noise level as monoblocks but cannot be easily stowed after use.

Split-System Air-Conditioner

A split-system not only consists of the body but always have at least two components. In addition to the cooling section, there is the compressor unit.

In your room, you will have the cooling unit installed while the compressor is always outdoors. Both parts are connected only by a thin hose through which the refrigerant flows. At the same time, the heat extracted from the room flows into the device.

The multi-split devices with good cooling capacity usually consist of up to ten individual parts, which are connected to an outdoor unit. With these air conditioners, rooms up to a size of 35 square meters can be cooled without any problems. However, the assumption is that there is no direct sunlight.

Although split devices initially cause more workload and higher costs, the energy efficiency over the months will allow you to get more bang for the buck.

If, on the other hand, you only want to cool the room occasionally, you will be better advised to get a monoblock device

Advantages of an Air-Conditioner

It must be distinguished between the individual versions of air conditioning units. In addition to the advantages of the monoblock devices, you should always take a look at the advantages of split devices and compare them.

Advantages of Monoblock Air-Conditioner

Monoblocks with solid cooling performance are characterized by the fact that they can be set up in a few simple steps. You can buy the air conditioning units starting from very low prices. Only the exhaust hose needs an attachment.

Besides, the mobile air conditioner can be transported from one room to another. Anyone who wants to cool the living room during the day, but wants to cool the bedroom at night, is well advised to use the mono unit.

Also, no installation work must be done. According to customer opinions and independent tests, you plug it into the socket and apply the required temperature. 

When the summer is over and the cooling of the air is no longer needed, the monoblock air-conditioner can be stored easily.

Advantages of Split-System Air-Conditioner

The big advantage of split devices is that they are not only more efficient than mono devices, but also suitable for larger rooms.

Rooms up to a size of 35 square meters can be cooled with these air conditioning units. No warm air flows from outside to inside, as the split units transport the warm air outside thanks to the external compressor.

The split-system air conditioners are on a much lower noise level. Since not always warm air flows in, the advantage is also noticed on the electricity bill.

Air-Conditioner Tests - Which Criteria Are Important

In external air conditioner tests, different air conditioners from numerous manufacturers have to pass various tests. Basic features and services are tested. In addition to the cooling result, the focus is also on the following factors:

Energy Consumption

Energy consumption is measured not only in the short term but also in the long run. Air conditioners with a bad efficiency class can cost more than US$50 a month. Pay attention to power consumption when buying.

Cooling Capacity

The higher the cooling capacity, the higher is the consumption. Countless air conditioners tests also pay attention to how efficiently the cooling takes place.

In addition to the cooling performance, the temperature indicated on the display on each unit is tested. Will the room be at the same real measured temperature as indicated?

Noise Level

When an air conditioner unit is running, the noise level should not be too loud that it interferes with everyday life. It does not matter if the room is cooled efficiently if you cannot hear your TV anymore.

Independent product tests determine whether the dB specifications given by the manufacturer is fulfilled. Every person has personal pain thresholds.

Heating Function

Some models also have the functionality of heating the air, in addition to the cooling function. Test portals check how efficient this function is in the air conditioning units and how high the power consumption will be.

Extra Functionalities

The focus is mainly on whether the extras delivering what the manufacturers promise and who can benefit from these additional features.

What Does an Air-Conditioner Cost?

Air conditioners have a diverse range of prices. Already with the monoblock devices, is it difficult to mention a price range. Cheap devices can be bought at prices around US$270, while the price for very high-end models can be astronomically high.

If you want good cooling in the air, you should not save money on the air conditioner unit.

Of course, the slightly higher investment also has a positive impact on the electricity bill. The better the energy efficiency class, the less increase in your monthly bill.

You should ask yourself in advance whether additional functions for your own needs are needed. Check if it is just a gimmick that you can easily do without.

Is an Air-Conditioner Dangerous For Your Health?

An air conditioner is not dangerous to health. However, there are two things to keep in mind. On the one hand, this would be the temperature difference between inside and outside temperatures: if the difference is too big (more than 6 degrees), some people get circulatory problems or quickly get a “summer cold”.

Another risk factor is bacteria, which can be spread through an air conditioner. Because an air conditioner releases cold air but is itself warm, it is the perfect place where bacteria can grow. For this reason, air conditioners must always be well maintained, especially in offices and airplanes.
