Mobile air conditioner purchase advisor

A mobile air conditioner is quick and easy to install and can be easily transported from room to room. Therefore, a mobile device is especially recommended if it is not operated permanently and you want to buy a cheap mobile air conditioning system for the sporadic use in extreme temperatures. However, the offer is very diverse and the different types can make it difficult to find the best mobile air conditioning system for your needs.

The recommendation is therefore to look in advance at the different types of air conditioners and energy efficiency classes before making a price comparison between eligible appliances. When comparing, make sure to pay attention to the different equipment features, because these are sometimes quite different from each other. To help you make your decision, you will receive the top 5 list of the best mobile air conditioners in 2019.

Types of air conditioners

Usually, air conditioners are differentiated according to the design, which means that they can be divided into three main groups. In addition, there are of course other distinguishing features according to the range of functions, technical features and functionality. Below is a brief overview of the different types of air conditioning systems that may be more or less suitable for your purposes, depending on the application:

1. Split air conditioners:

This type of air conditioner is not just a single device, it consists of two components, an inner and an outer part. In addition to the cooling section, there is also a compressor that must be installed on the outside. Usually fixed air conditioners are split units. However, there are also mobile split air conditioning systems, which are particularly suitable for use in mobile homes or caravans are used. The big advantage here is the low volume, as the louder unit can be put outside.

2. Mono-conditioning units:

In this design, all the required elements are installed in a large air conditioner. As a rule, the devices consist of a large body and an exhaust hose, which, depending on the mode of operation, conveys water or only steam to the outside. The exhaust hose is simply put through the window or the door to the outside. This limits the area of ​​use to locations where a door or window is nearby.

However, the big advantage is that the devices can be quickly and easily transported from one room to the other when you do not need them. Depending on their size and performance, rooms up to a size of 50m² can still be cooled effectively, but the recommendation is to think about the purchase of a stationary air conditioning system for rooms over 30m². In particular, since this monolayer is relatively loud and therefore only suitable for use in the bedroom.

3. Compact air conditioning units:

This is an intermediate solution between stationary, permanently installed devices and the mono devices that are simply released. Compact air conditioners are also attached to the wall near a window or door and the warm exhaust air is channeled outside. They consist of only one element and can therefore be installed and dismantled quite easily in comparison to fully-fledged air conditioning systems. Nevertheless, a certain amount of work before commissioning is necessary, which is higher than with monoclimatic devices. With regard to the volume, a compact device causes a level similar to the mono devices.

Energy efficiency

Most mobile air conditioners in the price entry area work much more inefficiently than stationary devices. In particular, older models on the market often have a very poor energy balance, which makes them suitable only for short-term use. The more frequently the device is to be used, the more likely it is to invest in a stationary device or, if this is not sensible, high-quality mobile device.
In the meantime, the EU has extended the climate table for air conditioners to A +++ and new appliances must have at least energy efficiency class B.

The purchase of a C, D or E device is therefore strongly discouraged if it is used very often or even operated permanently. In conjunction with the energy efficiency class it is also worth taking a look at the cooling capacity. This ERR value is expressed in watts and describes the relationship between power consumption (in watts) and cooling capacity (in watts). The higher this value, the more efficient the device works. What exactly the value means, illustrates the following calculation example:

An ERR value of 5 means that for the air conditioning of a room that requires a cooling capacity of 5 watts, one kilowatt of energy has to be used. If you are looking for the most efficient device possible, you should look for a model that works with the “air-water principle”. Compared to the simpler “air-to-air cooling principle”, these devices operate with significantly higher cooling capacity, making them more energy efficient. In the air-water process, part of the condensed water is returned to the unit and used to cool the condenser.

Additional equipment and product features

The different models differ quite clearly in terms of their features and the included accessories. It is therefore worthwhile to take a look at it. Depending on where you want to use the device, you should definitely compare the maximum volume in dB, because a very loud device can be used in the bedroom only conditionally. In general, a noise level of 65 dB should not be exceeded, because from this value it is usually perceived as very unpleasant. The less, the better of course.

Furthermore, some manufacturers provide a suitable remote control to the device, making the operation much easier and more convenient, especially if the device is further away or even built up. Pay attention also to the length of the supplied exhaust hose, because depending on the place of installation you need a minimum length, so that you can set up the device at all.

In addition, many manufacturers offer so-called combined devices, which can be used in addition to cooling for heating or dehumidifying the air. This may allow the device to be used for various purposes throughout the year. Usually, such combination devices – especially if they work powerful and energy efficient – significantly more expensive than pure cooling devices. Very favorable hardware store offers of combined appliances, which promise a high heating and cooling performance, are therefore to be treated with caution.

5 best mobile air conditioners (test) 2019

If it gets very hot in the summer, but you do not have air conditioning, it may be worth using a mobile air conditioner to cool individual rooms or a mobile split air conditioner for caravans or garden sheds. You can buy a mobile air conditioner without exhaust hose, or opt for a model in which a hose, the warm exhaust air outwards. Which models are recommended in the respective categories and price ranges, was determined in the test of the best air conditioners in the year 2019. The results can be found in the top 5 list of test winners.

1. De’Longhi PAC N81 mobile air conditioner

As the best mobile air conditioner, the device of De’Longhi prevailed. Although priced it is in the upper midfield, but convinced by a strong cooling capacity of 2,400 watts (equivalent to about 8,200 BTU) and works with the air-air technology. As a result, the condensate is recycled and does not have to be discharged to the outside. Only the water vapor which is produced must be led to the outside via the exhaust hose. The exhaust hose has a diameter of 12.5 centimeters and it is recommended to order a suitable window seal for this diameter.

Such seals – which do not differ from those for a vented dryer – are already available for well under 20 euros. The energy consumption is about 0.9 kWh per hour and the noise level is also limited with 63 dB under full load and was not bothersome by most testers. This allows you to use the 44.9 x 39.5 x 75 cm and about 30 kilograms heavy equipment for cooling rooms up to about 50 m².

The device operates with energy efficiency class A, can be operated intuitively directly on the device or by remote control and offers an overall very good performance. If you are ready to dig deeper into an air conditioner and really want to cool a living space efficiently without having to fill up with water or condensate, then it’s worth buying De’Longhi’s PAC N81 every case.

2. Trotec mobile air conditioning unit air conditioning PAC 2000 E with 2.1 kW

The air conditioning unit from Trotec was particularly convincing due to its good price-performance ratio and compact design. With a weight of about 24 kilograms with overall external dimensions of 30 x 37.5 x 80.7 centimeters, the device is despite the good cooling capacity of 2.1 kW (equivalent to 7,200 BTU) and is suitable according to the manufacturer for rooms up to one size of 65m². Under real conditions, however, this is somewhat high.

An effective cooling capacity with warm outside temperatures is only possible up to a room size of about 40 to 45 m². The scope of supply includes a remote control in addition to the device itself, so that you can also operate the device remotely without having to control the device yourself. An exhaust hose with a diameter of 14.2 centimeters and a length of three meters is also included with the package so that you can put the air conditioner into operation immediately.

With a noise level of 65 dB in accordance with EN ISO 3745 standard, the device also works just as quietly as many a much more expensive version. The maximum dehumidification capacity is 0.75 liters per hour with a maximum air flow of 330m³ per hour. Thanks to the Energy Efficiency Class A, it is energy-efficient and efficient, so it pays off for continuous operation. As an entry-level model, the TROTEC PAC 2000 E is therefore highly recommended.

3. Gree mobile air conditioning Shiny 9000 BTU climate 2.6 kW

The cheap mobile air conditioning system from GREE scores with its excellent price-performance ratio. It is fair to say, however, that despite a power of 2.6 kW, which corresponds to 9,000 BTU, it is not suitable for rooms over 30 – 35m² under real conditions, that is, it works much more inefficiently than more expensive models.

Nevertheless, it offers a very good performance in small rooms and in conjunction with the very low entry-level price, it is still economically viable over the total cost per year when used occasionally. It has a condensate recycling system, so that only the water vapor must be discharged through the exhaust hose. A remote control for remote control is also included. The batteries for the remote control are also included, so you can use it immediately and control it comfortably. With a size of 78 x 29 x 37cm, the device is pleasantly compact, allowing it to move quickly from one location to another.

4. Euromac Eurom AC 2400 air conditioning for caravan caravan

Eurom’s mobile split air conditioning unit consists of two elements and is ideal for use in mobile homes, garden sheds or other small units. It works with a power of 350 watts and achieves a cooling capacity of 700 watts or 2,400 BTUH with a current consumption of 1.53 amperes. You need a 230 Volt connection for operation. Thanks to the two-part superstructure, with the compressor on the outside, you can achieve a very low noise level of around 50 dB in the interior, so that you can sleep well in the caravan or motorhome despite running air conditioning.

The outer element reaches a maximum volume of 58 dB, which is also relatively quiet and adjacent campers on a campsite does not bother. The indoor unit has a weight of 6.8 kilograms and the outer element weighs 12.7 kilograms. The dimensions are 39.5 x 36 x 18 cm inside and 43.5 x 41 x 20 outside. Thanks to the very flat cable and hose guides, the window can be almost completely closed without the need for additional sealing.

The inner part can be controlled by LCD display and the outer part is merely placed in headband, the assembly is therefore quite simple and comfortable. Energy efficiency rating is E, which corresponds to an air flow rate of 4.15m³ (inside) and 25m³ (outside) per hour for these specifications. If you are looking for a mobile two-piece refrigerator, the model can be fully recommended despite the fact that it is quite expensive.

5. Suntec Wellness 12303 Klimatronic mobile air conditioner

The mobile local cooling and heating unit from Klimatronic works with a cooling capacity of 9,000 BTU per hour (2,600 watts). The same applies to the heating power. It works very efficiently, which is reflected in efficiency class A + (cooling) and A +++ (heating). The air circulation is very high with 400m³ per hour with three adjustable ventilation levels and the dehumidification performance is also very good at 2.1 liters per hour.

A remote control is included as well as a matching exhaust hose with a length of 1.5 meters and a matching connector. You should also order two AAA batteries for the remote control, these are not included in the delivery. The temperature can be set manually in a range between 15 to 30 degrees and separately, if necessary, the dehumidification function can be switched on.

Overall, the device measures 50.5 x 78 x 30 cm and weighs 27 kilograms reliably, efficiently and relatively quietly at 65 dB despite its high output. The power consumption during cooling is approx. 1.0 kWh and for heating approx. 0.8 kWh. Priced the device is located in the upper area, so that a purchase is only worthwhile, if you also use it regularly.
