Mobile air conditioner without air duct

Mobile air conditioner without duct is a convenient household appliance for cooling and air conditioning. Its main advantage is the possibility of installation in a room without time-consuming preparation and installation - mobile air conditioners do not require connection to the duct and a hose for condensate drainage. By the principle of action they are called evaporative type air conditioners.

Principle of operation and operating conditions

Remember the feeling of coolness after bathing on a hot day when a light wind blows damp skin. In this case, the physical process of evaporation of water occurs, and the result of this process is a sharp absorption of heat from the environment. Air cooling in air conditioners of the evaporative type is based on this property of water: to absorb heat when passing from the liquid state to the gaseous state.

The air conditioner has a sponge filter that absorbs water from a special reservoir. The jet of air pumped by the fan passes through this filter and evaporates moisture from it. At the same time, heat is absorbed, and air passing through the air conditioner is cooled. Maximum efficiency is achieved when the air temperature in the room is above 25 degrees Celsius.

Mobile air conditioners are available in the floor version. They do not require air from the street through the duct, however, the influx of fresh air allows not only to cool, but also to refresh the air, to normalize its humidity. Therefore, it is not recommended to use such air conditioners in tightly closed premises and cellars - air, even after cooling a few degrees, remains stale.

Advantages of mobile air conditioners

In addition to the mobility that makes it easy to move a mobile air conditioner from one room to another, there are a number of other positive features of the device:

• The compact dimensions allow to install it in any room;
• Mobile air conditioners are designed to cool rooms up to 25 square meters;
• The temperature drop in evaporation mode is gradual, while the humidity of the air is normalized. With this cooling mode, the risk of getting cold is minimal.
• High ecological compatibility of the device: it does not use refrigerants, cooling takes place only due to evaporation of water;
• Easy to operate - buttons and switches are located on the body of the device, some models are equipped with remote control;
• A wide range of models with additional functions: heater, air ionizer or ice container, allowing to quickly reduce the temperature, as well as the ability to work in fan mode;
• Mobile air conditioners do not require qualified installation and connection to air supply and condensate drainage systems;
• Low power consumption with high cooling output;
• A moderate noise level that does not exceed the noise of the outdoor fan.

The shortcomings of mobile air conditioners can be attributed only the inability to work without the influx of fresh air.

Choosing a mobile air conditioner

Before you buy a floor mobile air conditioner without a duct, you need to understand the desired characteristics.

• First of all, you need to pay attention to the maximum area of ​​the room, which can cool the device. Most models are designed for a space of up to 20-25 square meters, but there are also more compact air conditioners.
• The second important characteristic is the list of modes. Mobile air conditioners, depending on the modification, can operate in several modes:
• Cooling and humidification mode. It is achieved by evaporation of water from the filter.
• Fast cooling mode. In addition to cooling during evaporation of water cooling of the jet of air is added when it passes through a container with ice. Ice is laid in a special tank.
• Fan mode. Works without using water.
• Heating mode. The fan blows air through the heating element, causing the temperature of the air jet to rise.

It is also necessary to pay attention to the possibility to change the intensity of cooling or heating by selecting the fan speed and the power of the heating element.

1. If the floor air conditioner without duct is used in different rooms - check the convenience of its transportation. Well, if the chosen model is equipped not only with wheels, but also with handles on the body, facilitating its transportation. The weight of the air conditioner is also important.
2. Check whether the selected air conditioner is equipped with a condensate evaporation system. If not - you will have to drain it from time to time.
3. Evaluate the ease of management. The control panel can be either touch or mechanical. Some modifications are equipped with a control panel.
4. Check the passport noise level: 50 dB - this is a significant sound background, and if the air conditioner will be used constantly, it is worth looking for a model with lower noise values.
5. The manufacturer also has a value: well-known and well-proven brands differ not so much by the increased quality, as by a wide network of service centers. Therefore, when buying it is worth to clarify the warranty period and conditions for repairing the air conditioner in case of its failure.
6. Additional options depend on the model, with the increase in functionality, the price also increases. Useful options include air filters on the rear panel - they clean the intake air from dust and microparticles, thereby not only prolonging the life of the air conditioner, but also cleaning the air. Modes that allow you to turn off the air conditioner or change the modes of its operation by timer, as well as the regulation of airflows will make the atmosphere in the house comfortable at any time of the day.
