Mobile air conditioning: a quick solution with many disadvantages. Why is fixed air conditioning better?

Mobile air conditioning versus fixed air conditioning. Which is best for your space? When it comes to choosing the right air conditioning system to suit your requirements, the decision often comes down to a choice between mobile and fixed air conditioning. Both options have their advantages, and understanding the key differences can give you a clue as to which option is the better one. But does a fixed air conditioner have an advantage over a mobile one?

To help you make the right choice between fixed and mobile air conditioning, we’ve put together this guide. We explore how both systems work, how much they cost to install and we also evaluate the pros and cons of each system. But first, how does an air conditioning system work?

How an air conditioning system works

Air conditioners work by removing heat from inside your home and pumping it outside, while simultaneously releasing cooled air back into the room. More specifically, warm air is drawn into the air conditioning system through the evaporator’s cold ducts, cooling the air while the dehumidifier removes condensed moisture.

The principle is simple. The refrigerant flowing through the pipe absorbs heat and evaporates, changing it from a cold liquid to a warm gas. The heated refrigerant flows through the compressor and condenser. This turns the liquid back into a gas that is recirculated back into the room, cooling everything and reducing humidity.

What is mobile air conditioning

In the case of mobile air conditioning, it is a mobile unit designed to cool individual rooms. Unlike fixed air conditioners, it does not require permanent installation. It is usually on wheels so it can be moved from room to room as required. It is supplied with a hose that takes the hot air out of the room. As a rule, these components are installed on the window.

How much does it cost to run a mobile air conditioner?

A mobile air conditioner is usually 50% cheaper to run than a fixed air conditioner, simply because it tends to be used on a much smaller scale. However, the hourly cost of running a mobile air conditioner will vary depending on the size of the unit and its energy efficiency.

The operation of a mobile air conditioning system depends on several factors such as the energy consumption of the equipment, the operating time and the price of electricity. In comparison, mobile air conditioners are usually less energy efficient than fixed systems because they use more energy to cool the same room. The average energy consumption of a mobile air conditioner is between 1.2 and 2.5 kWh per hour, which, depending on the price of electricity, can mean a monthly cost of between €15 and €30 in normal use.

On the other hand, fixed air conditioners are usually more efficient, which can reduce operating costs, although the initial investment and installation are higher. Thus, the total cost of operating a mobile air conditioner is largely influenced by its heavy use and the length of time it is cooled, while regular maintenance can contribute to long-term efficiency.

How effective is mobile air conditioning?

Compared to fixed air conditioners, mobile air conditioners are less efficient for several reasons. They take considerably longer to cool a room and they also produce extra heat. We already mentioned that mobile air conditioners require an exhaust hose, this is because of the heat they generate when they cool a given space.

An exhaust hose attached to the window will help remove some of the heat generated by the air conditioner, but not all of it. That’s why you should always place a portable air conditioner close to a door or window to push out as much heat as possible. In addition to the heat generated, a portable system can also be quite noisy because the compressor, which is usually located outside of the living space with fixed air conditioners, is built into the same mobile unit.

What is fixed air conditioning?

Fixed air conditioners, often referred to as split systems, are permanently installed systems. These units are usually more powerful than mobile units and are designed to cool larger spaces. With fixed air conditioners, there are several types, each system also having its own specific features.

How much does it cost to run a fixed air conditioner?

Fixed air conditioning is usually cheaper to run than mobile units, as these systems are more energy efficient and can cool large spaces more effectively. The average energy consumption of fixed air conditioners is between 1 and 2 kWh per hour, which means lower electricity costs compared to mobile units. Depending on the size of the room and the operating time, monthly energy costs can range between 10 and 20 euros. Add to this the cost of regular maintenance, such as cleaning filters or checking the cooling, which can affect the total cost of operation. Although the initial investment in a fixed air conditioner is higher, its long-term running costs tend to be lower, making it a more economically viable option if used regularly.

How effective is fixed air conditioning?

Fixed air conditioners are generally considered to be one of the most energy efficient types of air conditioners. Another advantage is that they can serve as a full-fledged heating alternative in winter. This gives you the opportunity to reduce the consumption of your central heating system and potentially help you save money.

Comparison of energy efficiency

As mentioned earlier, mobile air conditioners tend to consume more energy for the amount of cooling they provide, especially when compared to modern fixed systems. The energy efficiency of a portable air conditioner is often measured by its EER (Energy Efficiency Ratio).

Fixed air conditioners, especially split systems, are known for their energy efficiency. Many modern models are equipped with inverter technology that allows the system to adjust its cooling capacity as needed. The result is lower energy consumption and lower electricity bills over time.

Maintenance

Maintenance of mobile air conditioners is relatively simple. It requires regular cleaning of the air filter, which is easily accessible and removable. But in general, these units are less durable than fixed units and so are highly likely to be replaced much sooner.

On the other hand, fixed air conditioners require intensive maintenance, including regular servicing by a professional. The outdoor unit will need to be cleaned regularly, and a regular refrigerant check is also required. While this maintenance is more demanding, it ensures the efficient operation of the system and extends its life.

Conclusion: what is best for your space?

Both mobile and fixed air conditioners have their pros and cons, and the best choice depends on your specific needs. If flexibility and affordability are your top priorities, mobile air conditioning may be the way to go.

However, if you’re looking for a long-term, efficient solution that can handle larger spaces, a fixed air conditioner is probably a better investment. Carefully consider your space, budget and cooling requirements before making a decision. However, don’t hesitate to contact the experts at Slovklima.sk, who will be happy to advise you well on your choice of air conditioning.
