The reader will get acquainted in detail with rating companies that produce devices designed for air cooling, and will also learn how to properly install a floor-standing air conditioner with an air duct.

A mobile air conditioner can not only create a comfortable microclimate, but also clean the air from harmful bacteria

Design and principle of operation

The design of a floor-mounted air conditioner without an air duct is completely different from a split system and other types of similar stationary climate control equipment. Mobile evaporative models do not have a compressor and components necessary for circulating the refrigerant (freon). The floor-standing ductless air conditioner includes the following elements:

sponge water filter;
pump;
air filter;
fan;
water container.

Air-free equipment is produced in the form of a rectangular plastic or metal monoblock equipped with 4 wheels. Manufacturers produce models equipped with handles located on the sides or top of the device.

In front of the case in the upper part of the monoblock there are holes designed to supply air masses into the room. Manufacturers often equip such outlets with movable blinds, which are used to change the direction of cooled and humidified air. Adjustment is carried out manually. Some models have a function for changing the flow direction on the remote control. The air intake occurs through the grille on the rear side of the housing.

Before purchasing a unit, you need to understand how a mobile air conditioner works. This will allow you to make a meaningful purchase and not regret the money spent in the future.

Operating principle of a mobile air conditioner without an air duct Source strojdvor.ru

In a portable device, the working substance is cold liquid or frozen water. This medium, evaporated into the free space, is a neutral refrigerant when considering the operating principle of an open air conditioning system. The effect after turning on the equipment is the same as the feeling of coolness when a person comes ashore from a pond on a hot day. At this moment, moisture evaporates. The process is accompanied by a sharp absorption of heat. It is on this property of the aquatic environment that the operation of a ductless portable air conditioner is based.

Ice is pre-prepared in a separate container. Some manufacturers produce models equipped with helium pads for freezing water.

In floor-standing modifications of air conditioners without air ducts, the aqueous medium evaporates, which allows air to be cooled. The process is a phase transition accompanied by the absorption of heat due to the conversion of a liquid into a gaseous substance.

Cooling in the device is accompanied by minimal release of thermal energy. Therefore, a water-based air conditioner is made without a corrugated hose, which is used in other similar devices to discharge hot air outside. Another distinctive feature of a floor-standing evaporative device is the absence of condensation accumulation, because it moves along with the air mass. This principle of operation of the equipment allows you to humidify the air processed in the space where the climate control unit is located.

Cooling in a portable device is carried out as follows:

using a pump, liquid from the water tank is directed to the porous hydraulic filter;
a ductless portable air conditioner for a home sucks in and passes air through an air filter to cleanse the environment of dust and other particulate matter;
after soaking the sponge filter with water, evaporation occurs - the liquid takes heat from the air mass;
cooled air from the device is returned to the room.

A portable unit without a corrugated air vent is ideal for rooms where it is necessary to humidify the atmosphere and reduce the temperature from 5 to 7 °C.
The portable device is suitable for objects with small heat gains from household equipment, people, building structures, including windows, roofs and walls.

Floor standing air conditioner without duct

Recently, mobile air conditioners without ducts have appeared. They do not work using freon, but according to a different principle. Floor standing air conditioners without ducts differ significantly from conventional air conditioners in their characteristics and efficiency.

Design and operating principle

Main elements of a mobile ductless air conditioner:

Fan;
Porous element;
Water container;
Pallet;
Pump.

The fan drives air through a porous element that is moistened with water. When passing through it, the flow “tears” water molecules from the surfaces, due to which the air is cooled. Part of the water from the element flows into the pan, from where it is pumped back into the water tank by a pump.

Efficiency

The effectiveness of a floor standing air conditioner without a duct is questionable. Yes, indeed, when moisture evaporates, energy is absorbed and the air cools. But what happens next?

After 20-30 minutes of work, the air in the room is saturated with moisture. It gradually settles on everything in the room and condenses. During the condensation process, thermal energy is released - the room heats up. It turns out that heat transfer simply occurs.

In order for a mobile ductless air conditioner to work effectively, it is necessary to ensure that moisture is removed from the room. But warm air will inevitably flow inside through an open window or ventilation. It would seem that such an air conditioner will not work at all, but this is not so.

It will be able to provide cooling in its immediate vicinity, at a distance of 2-4 meters (depending on power). But its effectiveness depends on many factors, such as:

Air circulation in the room;
The volume of air inflow and outflow into/from the room;
Room air temperature;
Supply air temperature;
Area and volume of the room.

Advantages

Despite the fact that mobile air conditioners without ducts are ineffective, they have their advantages:

Low cost;
Low power consumption due to the absence of a compressor;
Long service life (except for the fan and pump there are no parts subject to wear);
Lack of air ducts;
Compact dimensions of the device;
Air purification from dust;
Humidifies dry air;
Availability of a heating element for operation in heating mode.

Flaws

Low cooling efficiency;
It is not possible to set the required temperature inside the room;
It is necessary to add water;
The efficiency of heating mode is 2-5 times worse than that of conventional air conditioners;
Without ventilation, the room becomes stuffy after 10-20 minutes.

Pros and cons of ductless floor standing portable air conditioners

When choosing mobile floor air conditioners without an air duct, the pros and cons of the equipment must be taken into account. Therefore, it is necessary to understand the advantages and disadvantages of climate humidifying devices with the effect of cooling the air environment.

Equipment advantages

There is a wide range of devices on the market. The owner of a country property can purchase equipment with embedded software, a thermostat and a timer. Manufacturers produce climate control devices without an external unit, operating in automatic and customizable modes, each of which allows you to set the required temperature in the room.

Other advantages of the device include the following features:

It is possible to operate simultaneously in cooling and humidifying mode.
Light weight, which for models in a plastic case does not exceed 6 kg. This allows the water conditioner to be easily moved around the house and transported even over long distances. Moreover, the models are equipped with small wheels.
It is possible to turn on only the ventilation mode at different speeds or heating.
Good efficiency due to the operation of only one fan.
Louvre curtains at the air outlet allow you to adjust the direction of flow.
In cooling mode, power consumption is a maximum of 85 W.
The temperature drop occurs smoothly, so there are no drafts in the room.
Compact dimensions, which are 100-120 mm smaller in width, depth and height compared to the dimensions of models equipped with flexible air channels. This allows you to install climate control equipment anywhere in the room.

There are a number of other advantages of a portable air conditioning device:

High reliability due to simple design.
There is no need to lay inter-unit communications due to the absence of an outdoor unit. There is also no need to install a drainage hose.
Low noise level, not exceeding 45 dB. In this parameter, an air conditioner without an air duct outperforms equipment with an air duct, since the latter’s noise level reaches 50-56 dB.
Simple installation because there is no need to expose the corrugated air duct to the street.

The water portable climate control device is controlled using a remote control or a mechanical or touch panel on the body. Here are the buttons for selecting modes, temperatures, additional functions and turning the device on and off. The panel may also contain an indicator showing the water level in the pan. The equipment is characterized by increased safety due to the absence of freon, which is used in stationary devices for heat transfer.

Equipment disadvantages

Air conditioners without outdoor outlets have a number of design flaws that cannot be ignored. The main disadvantages of the equipment include the following disadvantages:

low efficiency in large rooms;
the need to constantly monitor the presence of water in the tank;
to increase the efficiency of the evaporation unit, it is necessary to ensure a stable supply of a small amount of air from the street in a private house so that excess moisture can be removed from the home, but heat will begin to flow into the building along with the fresh environment;
inertia - a mobile air conditioner without an air duct slowly cools the air environment, because water used as a working substance is not a highly volatile liquid;
during operation of the unit at the site, there is a strong increase in the level of humidity, which significantly affects the decrease in the rate of the evaporation process;
when using ice, it is necessary to freeze the water in advance in the refrigerator, which is a source of heat;
The average area of a serviced room is 24 m².

Despite the popularity of portable ductless climate control equipment, users note that the units only cool indoor air to 23°C. A slight decrease in temperature occurs exclusively locally - in the place where the air mass leaves the device. However, at other points in the room it will increase. After all, the components constantly generate heat during operation of the device.

Floor-standing air conditioner with duct: equipment characteristics

Floor-standing ducted air conditioners belong to the category of mobile devices designed to maintain a comfortable room temperature. Externally, the device looks like a small bedside table mounted on movable casters. Thanks to these design features, a mobile air conditioner can be installed in any convenient place.

Floor-standing devices perform the following functions:

indoor air conditioning and ventilation;
purifying the air in rooms from harmful impurities and dust;
cooling, dehumidification and heating of air.

Portable air conditioners are popular among owners of small apartments

What is the difference between air conditioners and split systems: how the devices operate

Many buyers wonder what is better – air conditioners or split systems. The operation of floor-standing devices is based on the same principle that is used in other types of climate control equipment, including separate split systems. The design operates due to two heat exchangers, a system of closed pipes and refrigerant circulating through them.

The design of split systems involves placing heat exchangers in two different blocks. When installing this type of air conditioner at home, one of the heat exchangers and the compressor can be placed outside the room, which reduces the noise level. The principle of operation of the devices is as follows: the refrigerant and heat exchanger absorb the heat in the room, then transfer it to the second heat exchanger, where it is already absorbed by the street air.

Floor-standing units contain all structural elements in one housing. All these parts are separated using a sealed jumper. This is the main difference between split systems and floor-standing devices.

Due to the ease of installation, a mobile floor air conditioner can be installed independently

Advantages and disadvantages of mobile ducted air conditioners

Advantages of floor-mounted air conditioners:

Mobility – the level of mobility is, of course, considered relative. In practice, such air conditioners can be called conditionally mobile. The presence of an air duct will not allow you to simply place the structure in any convenient place and turn it on; for this you need to perform certain preparatory work, which you can do yourself or order inexpensive installation of the air conditioner from the appropriate company.
Installation work does not require complex manipulations - this advantage will be especially beneficial for owners of apartments that have recently undergone renovations.
There is no need to obtain special permits to install equipment, which is a definite advantage for people living in rented apartments.

Installing a split system requires dismantling the walls to route pipes to the external unit

Floor-standing air conditioners also have disadvantages:

high noise level from a running compressor;
the mechanical components of the air conditioner generate heat during operation, so the air cooling efficiency is lower than that of split systems;
the absence of a drainage system designed to remove condensate requires additional care. The owner will have to remove the moisture accumulated during the air cooling process himself;
despite the presence of a thermal insulation coating on the air duct, this element of the system is still subject to heating, reducing the efficiency of cooling the room;
the system uses air from the room, so in the process of repeated cooling its physical properties are lost.

Mobile air conditioners of the Electrolux brand are considered one of the most reliable

Features of installation and operation of a portable cooler without freon

Along with the portable climate control equipment, instructions are supplied containing information on how to install a floor-standing air conditioner that operates without emitting hot air into the street. One of the features is the simple placement of the unit. To do this, you do not need to invite a specialist, whose help is required when installing stationary models. The placement of the device indoors is carried out without obtaining permission for installation, unlike split systems, the external units of which are prohibited from being hung on the facades of some buildings of historical value.

To take advantage of all the benefits of a portable open air conditioning system, you do not need to do the following:

drill the wall structure of the house;
secure the external unit;
lay a flexible duct outside to remove hot air;
connect the condensate drainage hose.

Installing a floor-standing air conditioner without a corrugated ventilation duct involves simply plugging the unit into an electrical outlet. The device is placed on the floor, bedside table or shelf in that part of the room in which it is necessary to reduce the temperature.

The instructions for climate control equipment note that it is important to follow safety rules. After all, a person uses an electrical device. Although portable equipment has a high level of protection against electric shock. An electric kettle is more dangerous than a floor-standing climate control unit.

It is also necessary to comply with sanitary standards, because the device contains a water container. The reservoir is in contact with the air. Therefore, bacteria, dust, fungi and other single-celled microorganisms enter the container. They must be disposed of after each operation of the cooling unit using disinfectants. The names of disinfectants are indicated on all packages of climate control units. Manufacturers recommend that tanks in open systems be washed twice with clean water and only then used for filling with working fluid.

Main details of the device

In order for the system to serve for many years, you should know not only the principle of its operation, but also the main functional details.

The main part of the floor system can be called the refrigeration circuit. It is he who is able to reduce the temperature of air flows to the required level. It consists of a compressor, a heat exchanger, and a device with an expander function.

There is a fan at the top of the device. It ensures air circulation inside the air conditioner.

There is also a fan at the bottom. It also helps air circulate and move through the vent pipe.

The floor-mounted air conditioner also includes an air duct pipe. It is necessary to remove excess air from the air conditioner to the street. Usually mounted in a window or in a specially prepared hole in the wall.

An integral part is also the remote control. With its help, you can set the required optimal room temperature, turn the device on or off.
