Among the range of climate techniques, mobile air conditioners are a special group without an air dilator. Instruments are air humidifiers with cooling effect. The devices are still called evaporative climate technique, manufacturers of which argue that the manufactured models are able to replace stationary household air conditioners, for example, split systems.

Mobile monoblock climatic device without corrugated air channel is a practical invention, which is an open air conditioning system. Using the device, it is possible to avoid reducing performance in humans and the emergence of various cardiovascular diseases. Outdoor air conditioner for home without an air duct designed to create a comfortable microclimate in the rooms.

Evaporated climatic equipment with the effect of cooling is necessarily useful if a person often moves. Mobile device can easily be delivered to another housing. Such a modification of the humidifier is often taken with me when renting a cottage for a vacation period or for a long time as a permanent place of residence. In the house a small water evaporator-cooler is used to create a comfortable atmosphere in the bedroom, children’s room, office.

Mobile air conditioners without an air duct. Principle of operation

The system is designed to create a cold without heat selection, because of which a separate air duct becomes simply unnecessary. Design features of the device are simplified due to the lack of condensate.

Mobile air conditioners without an air duct are accomplished. User feedback about them emphasize their following properties:

  • no available hose for condensate removal, various tubes and air duct;
  • Mobility that allows you to change the position of the device quickly and easily;
  • simplified installation and maintenance without intervention of specialists;
  • Cooling work consumes little electricity. 70 or 150 W, depending on the mode;
  • Outdoor mobile air conditioners without air ducts are reliable, thanks to a simple design;
  • a small weight of the device. from 6 to 12 kg;
  • Moves with the help of wheels at the base;
  • Low cost compared to split systems.

Disadvantages of mobile devices of this type

Also their negative moments have mobile air conditioners without an air duct. Reviews of many people indicate such weaknesses as:

  • the ability to use in small rooms. up to 25-30 m2;
  • greater noise level than in split systems;
  • It must be regularly filled with water;
  • The system has inertia. for the feeling of cold there is a lot of time;
  • moisture that evaporates while working, is going to the room, and therefore it is necessary to do ventilating. It must be remembered that mobile air conditioners for home without an air duct can not be used in the following rooms:
  • in closed rooms without windows and ventilation capabilities;
  • indoors with high humidity;
  • in basements.

Main working elements of mobile air conditioner with one or two ducts:

  • Compressor;
  • Freon highway;
  • Capacitor;
  • Evaporator.
  • Compressor. node that squeezes freon to increase its temperature. After compression, the gas is completely or partially moving into a liquid state and heats up.

Freon highway. copper tubes for which the refrigerant circulates in a liquid or gaseous state. They connect all the main nodes of the mobile air conditioner.

Condenser. a node in which the compression of Freon is compressor. Equipped with a radiator for refrigerant cooling due to air coming out of the room or from the street.

The evaporator is part of a mobile air conditioner in which Freon boils and goes into a gas condition. Equipped with radiator for heat selection by air from the room.

Auxiliary units of floor conditioner:

  • Main fan;
  • Auxiliary fan;
  • Condensate pallet;
  • Temperature sensor;
  • Controller;
  • Filters.

The main fan is used to blow the radiator of the capacitor, air intake of the room or the air duct. Auxiliary fan blows an evaporator radiator to more effectively cool the air flow in the air conditioned room.

Pallet for condensate accumulates moisture flowing from evaporator. In conventional air conditioners, it is discharged through drainage tubes. When using an outdoor air conditioner, the condensate accumulated in the pallet needs to be merged independently.

The temperature sensor gives the signals to the controller. That in turn manages the inclusion and disconnection of the compressor. In Inverter Mobile Air Conditioners, the controller is responsible for the speed of the compressor.

Through the filter passes air entering the radiator of the evaporator from the room. He delays a large dust. There are models with one filter, and there is two. The second purifies the air coming out of the room or the air duct to the condenser radiator.

Air conditioning floor portable without air duct

Household floor coolers on the domestic climatic device market appeared just a couple of years ago, but they deserve close attention. Most mobile models are equipped with a small pipe through which heat and contaminated air from the room occurs. As for today’s new items, it is a mobile air conditioner without an air duct connected to the power supply. No other connecting elements are provided.

On the peculiarities of the device of this unit, the principle of its work, the effect and will be discussed in today’s material. It is worth noting that outdoor solutions, despite their novelty, have already been widespread in the buying environment.

To begin, it should be said that all refrigeration units operate on the principle of heat exchange, which occurs in 2 radiators. One radiator takes heat from the room, and the second takes it outwards. All this system works with a refrigerant (freon), which moves from a liquid state into a gaseous and vice versa.

In our case, the principle of operation of the aggregate without an air duct is radically different from traditional models. It does not have a heat exchanger as such.

The device under consideration works as follows the air from the room is cooled by passing through a special air conditioner filter that is washed with water. The hydrophiltrost plays the role of heat exchanger in the unit, which is wetted by a small amount of water. In turn, the pump shakes water into a distribution device from a special capacity, which is at the bottom of the cooler. And behind the filter is a fan, with which the air flow is injected through a wet filter.

Air cooling by passing it through water-swamped filter

Manufacturers of these aggregates argue that the air is cooled by selecting heat for vaporization. After all, a great energy is needed for evaporation of water. So it turns out that the heated air, passing through the wet filter, causes water evaporation, giving his heat. Therefore, with such a system, the air duct for the removal of hot air is not needed.

The principle of mobile air conditioning

Also, in the cooler there is a “winter” mode. Using an electric heater (TEN), air heating occurs.

ADVICE! It is not desirable to use the aggregates of this type in completely clogged rooms, with the lack of any inflow of fresh air.

It is worth mentioning that the efficiency of these aggregates is largely dependent on fluid temperature. Than water is colder, especially more efficiently cooling the room. Another features of these devices can be distinguished by no mode at which you can set a certain temperature that the unit will support.

We recommend a short video about the principle of operation and efficiency of these aggregates

Each climatic device has both “pros” and “minuses”. Not devoid of them and portable mobile air conditioners.

Advantages of units without pipe removal:

  • mobility. The device is not tied to the air duct to the wall, so it is much more convenient to use it than traditional solutions. Movement is limited only by an electrical cable, the length of which can always be increased;
  • economy. Only 2 small units are located in the device housing. fan and compact pump. Their total power consumption does not exceed 130 W. In models where work is provided during the winter period (due to the electron heater), this value can reach 2 kW;
  • price. Mobile air conditioners cost an average of 30% cheaper than more bulky climatic complexes equipped with an air duct;
  • Fast effect. According to the completion of their device manufacturers, the temperature regime in the room is only 7-10 minutes after activation;
  • Easy operation. To turn on the air conditioner, it is enough to fill the reservoir with clean and cold water, and then connect the unit to the power grid;
  • Low acoustic background. Mobile coolers are really quiet and do not argue with it.
  • No opportunity to catch a cold. Since, unlike standard split systems, these aggregates are not able to blow with ice air.

But, as in any other technique for the house, portable air conditioners have certain disadvantages. The paradoxicality of the situation is that there are simply no “minuses” of this type of devices. It would seem that with his help you can solve the issue of cooling the room and refuse expensive climatic complexes, split systems. But here it is not so simple as it may seem at first glance.

The main disadvantage is that mobile air conditioners without an air duct in real operating conditions are not able to perform the main function. cooling air. Even schoolchildren are known. in the environment, energy does not arise from nothing, and does not go anywhere, it only changes its appearance, state and t.P. If you interpolate this through the prism of climatic devices, it turns out that it also requires the removal of warm air masses. This does not happen in the case of mobile air conditioning.

In the tank only decreases the volume of water, the temperature of which is growing during operation. The energy from the room does not go anywhere, but accumulates in small particles of water vapor. According to the similar principle, air humidifiers are arranged, that’s just real cooling does not occur. In the first hour of the unit, the temperature regime in the room can be reduced by 2-5 degrees, and then the stool arises (due to steam).


What is the effectiveness of such a device? In fact, air conditioning without an air duct responds to the ambient temperature, and the more significantly reduces the temperature than it is above. Another positive torque of water devices is noiselessness, as well as low energy consumption. A significant temperature reduction can be achieved only using compressor floor air conditioners.

And, of course, the biggest plus hiding in the title. The absence of the air duct provides truly ambit possibilities in terms of mobility. This also applies to the weight of the device, which due to this significantly decreases.

Installation of air conditioning yourself: how to install a mobile device

Since mobile devices regarding electric shock are practically safe (minimum level), many buyers are thinking about how to install air conditioner itself in the house.

Useful recommendations for installing climate equipment:

  • Before installing, you need to calculate the load so as not to overload the network. When ledge for an allowable energy flow rate of 5-10 kW, a capacity of about 3 kW will be optimal.
  • Putting a chipped outlet with a built-in UzO, you can exclude the need to install individual automata and grounding, as well as do without making changes to the wiring.

So that the air is always clean, it is necessary to clean the filters in the air conditioner from time to time

  • With a ceiling height of 2.7 m on cooling every 10 m², 1 kW will be required. If the ceilings indoors are high (4 m) to this value you need to add another 10%.
  • It is better to pick up more powerful devices, because due to automation, these indicators are regulated, and does not fix any ability.
  • Closed-type models are recommended to be installed in the corner, on the shelf or the end to avoid traces on the walls when emissions of the air jet. Open devices can be installed directly to the floor as close as possible to the zone that most needs cooling.

No matter which model of the air conditioner is installed in the house, it is important to comply with safety and hygiene norms: to operate appointment devices and according to the instructions, timely perform repair and scheduled service, change water and disinfect pallets.

How effective are portable air conditioners for home without an air duct

Buyers purchasing small air conditioning in the room are asked about its effectiveness. This manufacturers respond to the efficiency and performance increases with increasing ambient temperature. Outdoor air conditioner without an air duct in the house often has a ice compartment. Even with the strongest heat, such a device effectively cools the air, spending that through a special compartment. Instead of ice you can use simple cold water.

For small houses or offices, mobile flooring air conditioner is suitable as no other. it will effectively cool the existing area, while not causing inconvenience to use. For a large room, you will need a more powerful device. a standard split system, installed by the floor with a ceiling, or a climatic complex, which in its functions includes another air sink.

Portable Air Conditioner. No window? No problem! Vent exhaust thru wall, stealthy magnetic cover.

Portable mini air conditioning

Such devices appeared relatively recently and at first they were sold for a considerable amount. The manufacturer stated that it was well cooled, consume only 5 W per hour, and for normal operation you just need to pour water. But…

As practice has shown, mini-air conditioning is not effective at all. precisely, it can work as a weak fan, but no more. With the same success, you can put a computer cooler on the table and connect it from the battery.
