You can achieve coolness in the summer heat without installing an expensive split system. Perhaps mobile air conditioners without an air duct are not as powerful, but for owners of small city apartments they will be the best option. These devices are easy to install and not tied to one room - if desired, they can be moved from one room to another room.

Features and working principle

The principle of operation of a mobile air conditioner without an air duct is based on the ability of a liquid to act as a heat carrier. These devices significantly lower the temperature of dry air through the so-called phase transition of water from a liquid to a gaseous state. In other words, a somewhat modified process of its evaporation takes place. The energy required to vaporize water is extracted from dry air in the form of sensible heat, which is converted into latent heat . The process of this transformation is scientifically called isenthalpic. The unit in question operates in accordance with the characteristics of this evaporative cooling.

The main feature of the device is the fact that to remove hot air, ordinary water is used, which is poured into a container inside the device … Next, a special cooling mode is turned on, and the water moves to a special pump, after which it enters the filter. Warm air from the room also enters and passes through the fan. There heat is absorbed, and the air itself evaporates along with the cooled water. He enters the room already cool.

The liquid that remains inside the air conditioner is collected in a special container. The level of efficiency of the device depends entirely on the temperature of the water used. Therefore, the colder the liquid is, the more effective the result will be. Among the models of devices without an air duct, there are even options with special trays for ice . Another difference between mobile units without an air duct from conventional air conditioners is the lack of a clear temperature setting. However, the general principle of the system's operation is significantly simplified here. The lower the temperature of the water used and the hotter the room, the better the effect of this air conditioner will be. With optimal operation of the device, a temperature difference of about 10 degrees can be achieved.

Some portable air conditioners have air filters that purify the air by removing allergens, making them useful for people with respiratory problems.

Pros and cons

A portable air conditioner without an air duct is a popular household appliance for many reasons. One of them is mobility. However, e there are several other important aspects that should not be overlooked when choosing a device … First of all, you need to know the difference between a device with and without an air duct. An air conditioner without an air exhaust hose is also called an air cooler. It uses water and evaporation to cool the room, while a portable ducted air conditioner blows warm air out of the room through a window.

The main advantages of the device without an air duct

• High mobility, allowing you to move the device from room to room as needed. For example, use the device in your home office during the day and move it to your bedroom at night.
• Easy to install, which makes it possible to configure the device without the help of professional installers.
• The air conditioner operates without a branch pipe.
• Economical - the device will cost significantly less than a standard air conditioner.
• The small size allows the unit to be used in small spaces without the need for rearrangement.
• Convenient for those who rent office or retail space. If you move your office to another location, you can take the air conditioner with you.

The main disadvantages of the device without an air duct

• This is a rather noisy device compared to other types of air conditioners.
• It is necessary to monitor the amount of liquid that accumulates in the pan and pour it out in time.
• The inability to regulate the exact temperature.
• Lower efficiency level, making it suitable for small spaces only.
• Cannot be used in basements, rooms with high levels of humidity, or in rooms without windows.

Views

One of the most important aspects of using air conditioners without exhaust hoses is the low energy consumption. This is possible due to the fact that these devices do not use components with high energy consumption such as compressors. Users of standard split units with heating have to pay a lot for electricity, while owners of devices without an air duct can greatly save on electricity consumption.

There is an opinion that it is not entirely correct to call air conditioners without an air duct air conditioners. They are more like floor-standing air coolers. They are rarely silent. To cool the room, a cold liquid is used, which evaporates, cooling the air . On the principle of evaporation of cold liquid and without using a hose for air removal, such types of air conditioners as bioconditioners, mobile floor air conditioners and some types of window air conditioners can work.

Rating of the best models

The variability of manufacturers of floor-standing air conditioners is amazing. And if firms like Zanussi or Toshiba , everyone knows, and the quality of their products is not in doubt, then beginners like NeoClima or Aeronik you have to fight for good positions in numerous tops and ratings.

Zanussi ZACM-12 VT / N1

The ZACM-12 VT / N1 model of the famous Zanussi brand is distinguished by high power rates and neat modern design. Cools fairly large rooms without any problems.

Selection Tips

The list of mandatory parameters when choosing a mobile air conditioner without an air duct is somewhat different from the recommendations when buying a standard split system. For such a system, for example, it is very important to ensure the tightness of the room, while for a device without an air duct, it is necessary to maintain a constant flow of fresh air by keeping a window or door open. This is important both for the apartment and for the house. If you do not ventilate the room and keep the device on at this time, the humidity level in it will increase greatly. Points to look out for when choosing an air conditioner without duct.

• The maximum power, on which the size of the room will directly depend.
• The size of the tanks for chilled water and liquid under the drain. The larger they are, the less often you will have to change the water while the air conditioner is running.
• How loud the device is. The volume is typical for this kind of devices, so low-quality air conditioners make unbearable noise at times.
• The energy consumption level, which is usually indicated in the characteristics of the air conditioner model.

Since the constant circulation of water is especially important when the air conditioner is operating without an air duct, it is important to decide whether you will change the fluid manually or would prefer to master the control system for supplying fluid through a hose.

Many indoor models require manual water top-up . This is important in order for the cooling process in these devices to work without interruption. There are models that come with a hose that automatically fills with water. Appliances without a hose use less energy and significantly. For this reason, for those who want to save money, it is better to take a closer look at devices with a manual supply of water.

Exploitation

First of all, it should be understood that during the operation of the air conditioner, the owner will have to constantly monitor the liquid level in the device. The device operates on the principle of cooling an evaporating liquid. This explains the absence of pipes and corrugations and the fact that air circulation takes place inside the room without bringing the latter out to the street. It is also important to consider that air conditioners of this kind are most effective in the summer season, when the indoor temperature is above 25 degrees . It is not worth waiting for a strikingly high temperature difference before and after using the air conditioner. The device is optimal only for normalizing the atmosphere of the room in the hot season.

Tips to follow when operating the air conditioner without an air duct

• The device is best placed near a window.
• For maximum efficiency, the water container should be filled no higher than the critical level. The colder the water, the higher the efficiency of the appliance.
• The air conditioner cannot be used in completely isolated rooms such as basements. It is important to have a ventilation system so that it is possible to periodically ventilate the room.
• Do not allow direct sunlight to fall on the unit.
• For the most efficient operation of the device, ice pieces or special refrigerants can be added to the inside of a container with cold water.

Like other appliances, a ductless mobile air conditioner requires regular maintenance. This helps to improve the efficiency of the device. If the performance of the device drops, it is probably necessary to do preventive maintenance . In addition to increasing productivity, regular maintenance will ensure that the cold air entering the room is clean and free from allergens and germs.

Air in a room can contain a wide variety of pollutants. Some of these particles can accumulate on the surface of the evaporator and condenser coils. The accumulation of such particles reduces the overall efficiency of the portable device. It can also lead to a decrease in its power.

It is important to clean the air conditioner filter regularly . Air regularly passes through it, along with all harmful particles, which, in fact, by and large remain there. An environment suitable for the growth and reproduction of microbes is created. If the inhabitants of an apartment with a constantly working air conditioner suddenly begin to sneeze, cough or show any allergic reactions, it may be worth cleaning the device. If you do not have any experience in this area, it would be better to entrust it to specialists.

Review overview

Many users note the pleasant design and portability of portable air conditioners. They do not burden the room, and if desired, they can be easily rearranged to another room. Buyers are also attracted by the low cost of these devices in comparison with other air conditioners. Many of the disadvantages include the noise of the device . Many are also confused by the inability to switch the parameters of the required temperature. Users also complain about the difficulties that arise when it is necessary to regularly change cold water.

The trays fill up, the evaporation water cools quickly and the efficiency of the air conditioner decreases.
