The Air Conditioning System – Advantages And Disadvantages

Air conditioning systems are primarily used to lower the air humidity and filter the room air. Furthermore, air conditioning systems ensure a comfortable room temperature by cooling in summer and heating in winter.

Below you will find an overview of mobile and wall mounted air conditioner and split units and their respective advantages and disadvantages. However, heat pumps can also be used as air conditioning.

About air conditioning

Although air conditioning systems generate and maintain pleasant indoor air, a pure air conditioning system is not an alternative for the passive, zero energy or plus energy house.

This is because individual devices that are not connected to a ventilation system are energy guzzlers and quickly drive up electricity costs. In these cases, it is better to use ventilation systems that can also air-condition.

Mobile air conditioning systems – preferably not

Mobile air conditioners or compact devices are offered in all hardware stores for little money. If one looks at the energy consumption and the operating conditions, it quickly becomes clear that the purchase of such an air conditioning system makes little sense.

With compact units, the warm and moist exhaust air from the unit is routed to the outside via a hose through a window or door gap.

As a result, new warm air constantly enters the room from outside and the cooling effect is severely impaired. Even for allergy sufferers, these air conditioning systems are not an alternative to rid the air of allergens, as the constant opening means that new allergens are constantly being added to the room.

Other disadvantages of these devices are the high level of noise pollution and the lack of security against break-ins. The only thing that really runs smoothly with the mobile air conditioning systems is the counter in your electricity meter.

Split units – divided into an inner and outer part

Split units have a significantly better cooling performance than compact units have and are permanently integrated into the building.

The system is divided into an inner part (in the building) and an outer part (outside the building). Both parts are connected to each other via a pipe. In the interior of the system, the room air is led past an evaporator.

The room air is cooled by the evaporation of a refrigerant and moisture is collected in a collection container by shifting the dew point.

The dissipated heat is transported outside through the pipes, where it is released to the environment via the condenser of the cooling circuit.

The condensed refrigerant is then expanded and then returned to the evaporator. The condensed water in the interior of the system must either be fed to the wastewater through a pipeline or emptied manually from a collection container.

If several air conditioning systems are required in one house, so-called multi-split units are available. Several indoor units are connected to one outdoor unit in a network.

A heat pump as air conditioning

Since the principle of the heat pump is based on a cooling process, as is also used in air conditioning systems, it is possible to use the heat pump to cool the room in summer. The system can supply both heat and cold.

When carrying out an energetic basic renovation, it is, therefore, advisable to check in advance whether a heat pump is a sensible variant for the building in question and whether it can be used to cool the room in summer.

The principle of such a heat pump is very simple. The soil maintains a temperature between 10 ° C and 12 ° C all year round.

Reversible heat pump and natural cooling system – two systems for room cooling

With the reversible heat pump, the current flow of the heat pump is changed via four-way valves. This swaps component, condenser, and evaporator.

The refrigerant is evaporated by the heating system and the room air is cooled. The hot refrigerant is then condensed again in the colder soil. A reversible heat pump is, therefore, a refrigerator on a large scale.

In the natural cooling system, the refrigeration cycle is not used as such, but a circulating pump circulates the refrigerant. It is therefore, simply cool down in the ground and then absorb the heating system’s absorbed energy.

As a result, the rooms are cooled very slowly and gently. Furthermore, the circulation pump and the control unit work much more energy-efficiently than the entire heat pump.

Dew point monitoring must be installed in both variants. This must ensure that the room air is not cooled below 20 ° C, and thus moisture condensation on the floor or in the walls.

Wall-mounted air conditioners: equipment features

Wall-mounted air conditioners are popular split systems used in residential buildings. The scope of the equipment is very extensive. This type of air conditioner is suitable for installation in:

  • Apartment
  • Office
  • Home
  • Small cafes and restaurants
  • Trading premises

The principle of the wall air conditioner

The device has two operating modes: cooling and heating. Freon (refrigerant) evaporates when exposed to high ambient temperatures. This process takes place in the indoor unit.

Gaseous freon leads to an increase in pressure in the circuit, and the compressor raises it even more. The refrigerant moves to the outdoor unit, condensing and releasing a low temperature to the outside air. The process is repeated in a circle.

When working on heating, all of the above processes take place in the opposite direction. Wall-mounted air conditioners are complete air heaters. Devices can work on heating to -15 degrees.

Advantages of a wall-mounted air conditioner (Split System)

How is a wall-mounted split system better than other outdated types of home air conditioners?

Wall split system is one of the best air conditioners. In addition to a variety of designs and types, it is available in comparison with other units. Such a device is very useful in offices and homes, especially in summer. Many do not want any hassle with assembling air conditioners.

In addition to the main advantage of the split system – cooling, it has many advantages, including saving valuable space, especially if there is not enough space, but cool air is needed. Compared to other types, wall mounted air conditioner has many advantages. 

Perfect look and safety

One of the many advantages of a wall-mounted air conditioner compared to some other units, such as a window unit, is that the wall unit can be installed on the most convenient part of the wall, not through a window. The device will not block the view from the window.

This is very beneficial as you can still open the windows to let in the fresh air. This is also a safety measure, as most window air conditioners can be easily pushed.

Space-saving

Wall-mounted air conditioning saves a lot of space, as it is mounted high on the wall, not on the ground. It is suitable for small rooms in which another space can be used for other purposes.

Do not need to be assembled and disassembled

In summer, these air conditioners are very useful. Since it is very hot outside, everyone wants to relax or work where it is very comfortable and cool. In winter, the need for these devices is minimal.

Because of the space that is “eaten up” by other air conditioners, people dismantled the blocks for the winter, installing them again in the summer. The advantage of a wall-mounted air conditioner is that, due to its immobility, you do not have to remove it from its place.

Conclusion

Once you have trusted the experienced, proven specialists in the installation of air conditioners, you will forever forget about the problems associated with breakdowns and repairs. So just, think and choose wisely.
