What types of air conditioning are there?

There are several types of air conditioners. This has been done so that these teams are adaptable to different spaces and needs. Currently, splits are the most popular and represent an excellent option for their quality and price, although this may vary depending on the manufacturer. Here we show you the different types of air conditioners.

Types of air conditioningFunction / Feature
of windowThey are great for saving space and can be installed and removed with ease. You can find them small (5,000 – 6,500 Btu), medium (7,000 – 8,200 Btu) and large (9,800 to 12,500 Btu). It is recommended not to plug them in with extension cords.
LaptopsThey are versatile, as they can be mounted on wheels to move them and range from 9,000 to 15,500 Btu, with a weight of 20 – 40 kg. They do not usually cool as much as the other air conditioners. They work best in dry climates as they add moisture and require a nearby window to draw warm air out of the room.
WallSimilar to window air conditioners, except that they are installed on an exterior wall. For this reason they require protective chassis. They are ideal for spaces without ventilation. They are complex to install without professional help.
No split ducts (split)The splits are relatively easy to install as they do not need to drill any walls. They have excellent cooling capacity and are quite quiet. Mini- splits are made up of an outdoor compressor / condenser and an indoor unit, so they require a hole in the wall for the ducts to pass through. They can provide heating and with Inverter technology you can save energy.
CentralsThey are much more expensive, since they have great cooling power and the installation of their ducts can also be used for heating.
With wifiThey are smart air conditioners that have the ability to be controlled remotely through a mobile application connected to the Internet to maintain the desired temperature, and even save energy.

How does an air conditioner work?

Physical and chemical changes take place in an air conditioner. The cold air that we receive is part of a circuit that extracts the hot air from the environment and transforms it through the refrigerant gas, evaporating it. Then, the fan is responsible for releasing that new air through the exchanger.

Inverter technology has the ability to automatically regulate air conditioning temperature and fan speed. In this way, it remains stable between 9 and 12 degrees below room temperature. This is how the electricity consumption of this type of equipment is regulated.

The evaporator fan takes the air from the room it is in and forces it to circulate over the evaporator surface. This air, now hotter than the evaporator surface, transfers its heat to the evaporator fins through convection. The fins give their heat, by conduction, to the low-energy refrigerant vapor that was circulating through the evaporator. Finally, it passes over the evaporator, the now cooled air is reintegrated into the room.

How to install an air conditioner?

The installation of an air conditioner is relative to the equipment itself and its manufacturer. A portable type does not require installation, so it will take minutes to get up and running. For the other types, you must take into account the hot air inlet and outlet ducts, as well as the most optimal place for placement, which favors you and the team as well.

Brands typically offer detailed installation instructions for the equipment they sell. If you are a refrigeration expert or a handyman, it may be easy for you to cope with the different ways of installation. Otherwise, we recommend the supervision or help of a specialized technician who knows how to handle the equipment.

What are the BTUs of air conditioners?

BTUs in air conditioners measure the amount of heat that can be extracted from a room. It refers to the British Thermal Unit and usually appears in sections of technical information of these equipments. BTU per hour refers to the energy used to increase the temperature of 0.45 kg of water by 1 degree FH under constant pressure.

In turn, a BTU is equivalent to 0.29 Wh and represents 0.25 kcal per hour (frigories). This is usually the most commonly used way in Spain to evaluate the power of air conditioners.

What are the frigories of an air conditioner and how can I calculate them?

The frigories refer to the power of the equipment. To calculate them, we must start from the space that we want to temper to our liking. For this you must take into account: the height, the width and the length. Then, the result of the multiplication of these 3 measurements will give you the m ^ 3 of the room. Then, you will multiply the m ^ 3 by 50 and you will get the frigories you need.

We must also know the energy required by air conditioning. One frigory is equivalent to 1,163 W. So, if we multiply this number by the total number of frigories previously calculated, we get the cooling power. Here’s an example:

2600 frigories x 1,163 W = 30,238 kW

How to keep an air conditioner clean?

Cleaning air conditioners is essential for their operation and durability. The regularity with which you do this will favor the good condition of your equipment and you will obtain a good temperature and with much cleaner air. You must clean the entire device, both the internal and external parts. Filters are essential. Therefore, the best thing is that you check them every 3 months, to always keep them clean.

In accordance with what has been said, the drains must also remain free of obstructions, so we do not receive bad odors caused by dirt. The most difficult parts should be cleaned with a brush to remove what has accumulated with the dust. It is recommended to clean the condenser every season of the year. Although you can do it yourself, it may be difficult the first few times. For this reason, having a professional will give you the security of a correct job.

The COP is the operational coefficient, also called as energy efficiency. It refers to the relationship between the cooling power and the absorbed or necessary power that allow the operation of the air conditioning. Therefore, it is best to have a high COP in order to do so. , to achieve a lower consumption of electricity “.

Size

The size is a criterion that you must take into account to achieve an optimal placement of your air conditioner. Many times the purchase starts from here. For this it is recommended to measure the installation space and the equipment itself. In this way, we will ensure that it will be sufficient for the place we want to cool.

In addition, the weight of your air conditioner will also be important, so you will know if you need help in assembly and installation or the most resistant place of location. This information must be complemented with the type of room we have and the number of people who will be in it. Here we explain it better:

Room size in m ^ 2BTUs per hour of operation
9 – 27 m ^ 25,000 – 7,000
27 – 41 m ^ 28,000 – 10,000
41 – 51 m ^ 210,000 – 12,000
51 – 65 m ^ 213,000 – 14,000
65 – 92 m ^ 218,000
+ 92 m ^ 2+ 20,000

Power

Knowing the power that the air conditioning that we are going to buy will have is essential. However, first we must know the space we want to air condition. Now, you must be clear that electrical power is not the same as cooling power. The latter is measured by frigories, BTU or WH and the other in KW ( 1 ) .

Selecting the air conditioning with the appropriate power will help us both to achieve the desired temperature in the room, and to save electricity. Differentiating between these types of power will make your purchase a good choice.

Filters

The filters that our air conditioning will have are an essential criterion. Without a doubt, filters have the function of purifying the ambient air and, therefore, we breathe. However, they have the function of keeping the equipment free of dirt and dust.

There are different types of filters that will help you understand and better choose the one that suits your needs. Here we show you:

Filter typesFunction
Silver platingDust retention.
CatechinNeutralization of microorganisms.
DeodorizerAbsorption of bad odors.
Vitamin CRelease of vitamin C into the environment, to soften the skin and help reduce stress.
HEPA99.9% retention of particles larger than 3 microns.

Heat pump

Heat pump air conditioners are quite common in the market offers. Hence, today, the split type has incorporated this purchase criterion. So it will be very easy to find this type of heat pump air conditioner.

However, portable type air conditioners do not always have this heat function built in. These models that usually incorporate the emission of hot air have higher prices, by 20 and 30%. In some cases its price is higher than the split type .

Noise level

The noise level of air conditioners can be a very sensitive issue. Typically, this information comes in the description of the equipment. It is very important that you know that no air conditioner is totally silent, but they do vary according to the sound they emit.

In addition, split- type air conditioners emit a sound level of around 20 dB, while the portable type is higher, reaching 40 dB. This may seem difficult to understand, but to give you an idea, televisions and normal conversation are between 40 and 60 decibels.

Technology

Currently, Inverter technology for air conditioners is the best known and most frequent. It refers to a system whose purpose is to save electrical energy. This has brought with it more efficient refrigeration equipment than those that were formerly used, the fixed power ones.

Above this, Inverter technology is not usually added to portable air conditioners. This causes this type of equipment to be more expensive and represent a higher cost of electrical energy.

Power consumption

Energy efficient air conditioners are a priority for many. The electrical cost of these refrigeration equipment is usually explained on the equipment labels. Here you must take into account several indicators:

  • Those that indicate A +++ are the most efficient.
  • Those that point to the letter D are the ones that consume the most energy.
  • The Seasonal Energy Efficiency Factor (SEER) measures how efficient the equipment is for cooling.
  • The Seasonal Coefficient of Performance (SCOP) measures how good it is for heating in winter.

In addition, the higher the value of SEER and SCOP, the lower the consumption of the air conditioner. An A +++ rating will have at least 8.5 SEER and 5.10 SCOP. For example, if we increase SEER by one point, we increase energy efficiency by 10%.
