Features of using a mobile air conditioner without duct for home

Maintaining a comfortable indoor microclimate in summer is possible in various ways. Previously, split systems and other types of air conditioners were used. Now an alternative solution has emerged - water air purifiers or air conditioners. These devices use water to lower the ambient temperature. Outwardly, they are similar to mobile air conditioners, but the operating principle is fundamentally different.

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.

Service

Evaporative air coolers do not require special maintenance. It is enough to occasionally wipe the outer casing of the device with a damp cloth. The evaporator requires maintenance. It is cleaned at least once a month with warm water and a mild detergent to avoid the formation of limescale, dirt, mold and mildew. Depending on the model chosen, the evaporator may be a consumable item and can be replaced if the original cooling capacity is lost.

It is important to perform seasonal shutdown correctly. When the need for cooling passes, drain the water from the tank, disconnect the device from the power supply and cover it to protect it from dust. Turn on the fan function (if equipped) for 30 to 60 minutes to completely dry the unit before seasonal storage.

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:

1. It is possible to operate simultaneously in cooling and humidifying mode.
2. 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.
3. It is possible to turn on only the ventilation mode at different speeds or heating.
4. Good efficiency due to the operation of only one fan.
5. Louvre curtains at the air outlet allow you to adjust the direction of flow.
6. In cooling mode, power consumption is a maximum of 85 W.
7. The temperature drop occurs smoothly, so there are no drafts in the room.
8. 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:

1. High reliability due to simple design.
2. 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.
3. 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.
4. 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.

Simplified designs for the home

One of these designs is a water heat exchanger combined with a conventional floor fan. To make such a primitive cooler, you need to take a copper tube and roll it into a spiral, attaching it to the fan protective grille. For installation, you can use plastic clamps used to secure wiring in cars. The ends of the tube are connected to the water supply, and the fan is connected to the network.

The copper tube is attached directly to the fan grille

Note. The described design is ineffective because the tap water is not cold enough and the usable area of ​​the copper heat exchanger is too small. The air flow from the impeller will cool slightly and nothing more.

Bottled air conditioner is placed in the window opening

The original design was invented in one of the African countries, where it is traditionally hot and, in addition, there is no electricity supply. The device works based on a law of physics that states that the temperature of a gas passing through a sudden contraction and expansion drops by several degrees (up to 5 ° C). The neck of the same plastic bottle acts as such a narrowing, and to get more cooled air, you need to use a dozen of these necks.

To make it you need to drill through the plywood and cut the bottles

A non-volatile air conditioner is done like this:

1. Cut a piece of plywood or fiberboard the size of the window opening to be opened. Check how many bottles can be placed on it close to each other.
2. Cut off the necks of all bottles and twist the caps. Then place them on a sheet of plywood and mark the centers of the holes with a pencil.
3. Make holes with a core drill whose diameter matches the neck. Insert the cut bottles into them.
4. Attach plywood to the outside of the window opening so that the bottles stick out into the street.

Assembly is simple - bottles are inserted into the holes

The device is suitable for a country house where other options cannot be used due to lack of the required amount of water or power outages.

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.

Application area

A water air cooler is an effective solution for maintaining a comfortable microclimate indoors or in open and semi-outdoor areas. It works effectively in any of the following cases:

• On the street. Water air purifiers are ideal solutions for cooling the outside of a building. Applications include decks, back and covered patios, gazebos. For large open spaces, powerful industrial models are used.
• On verandas and terraces. Evaporative coolers are ideal for use in semi-outdoor areas regardless of humidity levels, such as garages and covered porches. When using in a garage, be sure to open the door slightly to allow fresh air to enter.
• Indoors. When using indoors, leave a window or door open for ventilation. The device works well in very dry and hot environments, but is not recommended for use in humid climates.

Evaporative coolers are popular in commercial applications because they are powerful, large, inexpensive to operate, and portable. They are suitable for climate control in warehouses, commercial event spaces, festivals, sporting events, loading docks, barns, etc.

Our online store offers several models for commercial and domestic use, such as Zenet Zet-483, Symphony Diet 8i, Symphony Diet 22i, Symphony Ice Cube 17i, Honeywell CS10XE with ionization, Honeywell CHL30XC with heating, Honeywell ES 800 with ionization. All equipment has passed quality certification and has a factory warranty.

How are complexes for industrial use different?

There are different systems to meet the needs of each enterprise. In one case, a block with two fans is sufficient; in another situation, several complexes with 3-4 fans in each are installed.

There are different classifications of air coolers. Equipment differs in heat exchanger area, number of fans, air mass flow, and size. The power of the system will affect the efficiency of using the model.

Installation features are also taken into account during selection. The complexes can be mounted on the wall, ceiling or floor of the refrigeration chamber. The choice depends on the layout of the chamber space and other features. The main characteristics of the fan units are calculated and indicated when designing the chamber.

Manufacturers and models of mobile air conditioning units without corrugated ducts

Those who don't want to read can watch the videos. They will clearly help you understand the structure, operating principle, advantages, and features of portable climate control equipment without an air duct.

How to choose an air cooler

The device does not require specific installation and laying of supply engineering networks. Just install it in any convenient place and connect to the power supply. To achieve the best cooling performance, make sure that the air conditioner is suitable for the size of the room. Equipment with insufficient power will consume excess energy and operate at the limit of its capabilities, which leads to premature wear of parts and can cause failure.

First you need to decide on the power of the device, it will depend on the volume of the room served. And there is a direct relationship between the power of the air conditioner and the quality of air cooling. Of course, this affects the price of the device, but compromises must be sought here.

When choosing a suitable model, rely on air flow (m³/h). Below is a table that allows you to select the appropriate equipment depending on the size of the room.

If several of the listed parameters are present in the room, use a multiplying factor:

• High ceilings. The table shows data for rooms with a standard height of 2.5 m. When increasing this parameter, it is necessary to apply a correction factor greater than 1.
• Window orientation. If the room is located on the south side and it is sunny during the day, additionally use a factor of 1.2.
• Number of residents. People are an additional source of heat; if more than two people are constantly in the room, you should use an air conditioner that is 20% more powerful.
• Appliances. If there are many heat-generating devices, for example, computers, copying equipment, server equipment, additionally use a correction factor of 1.2.

The second important step is to figure out what features you need. Will it be just cooling, or is air purification and ionization also necessary? Maybe remote control of the device will make you happy? Or will the presence of a timer be the deciding factor?

The third step is to read reviews from other buyers. This strategic maneuver will allow you to avoid some mistakes and immediately discard ineffective options.

Epilogue

The evaporative monoblock is the choice of people who rent houses for seasonal holidays or permanent residence. After all, such equipment can always be transported to another building. A mobile cooling device without an air duct allows you to create comfortable conditions in any small room in a country house. A portable device with water refrigerant is a godsend for asthmatics, because the air conditioning unit does not dry out the air, unlike stationary wall-mounted models.

Air cooler efficiency

Why is an air cooler so effective? The answer is simple: the effectiveness of an air cooler lies in its action, that is, on the heat transfer between the cooling and cooled media, which are separated by a solid wall. Don’t forget about safety precautions when connecting air coolers to electrical machines. In particular, when connecting, it is necessary to take measures to prevent water from entering open parts of electrical machines. In this case, it is necessary that when connecting water to the air coolers, the counterflow rule is observed, that is, the water must enter from the air outlet side of the air coolers. When choosing an air cooler, you should be guided by the main technical characteristics, which include: cooling water flow, air flow, cooling water temperature, cooled air temperature, heat flow, air cooler mass. The air cooler is designed only for a certain range of losses, which can be regulated by the amount of water flowing through the air cooler tubes. In order not to be mistaken by the technical parameters, in practice, the calculation of an air cooler is usually carried out with a margin of ten percent or more to their cooling capacity, with a possible decrease in the efficiency of their operation during periods of cleaning work. If we are guided by existing standards, then according to OST 16.0.684.001-79, it is recommended to take the reserve in the amount of 25 percent.

An important factor when choosing an air cooler is the choice of manufacturer. Since the design of the air cooler is entirely metal, it is worth considering suppliers located in regions where metalworking is their core activity. Due to the fact that the raw material base is nearby, the cost of manufacturing an air cooler is significantly reduced.

Industrial heat exchange equipment

Industrial air coolers are most often of the surface or dry type. This type of device is used for cooling electrical equipment, such as electric motors, hydraulic and turbo generators, etc.

Industrial devices are produced in the following series: VO; VUP; GP; VB.

• VO - heat exchangers of this series are used in enterprises where large electrical equipment operates. The principle of operation of the device: cold water circulates through the finned tubes of the heat exchanger. The air mixture coming from the mechanism comes into contact with the surface of the finned tubes, cools and returns to the mechanism. Heat exchangers of this series can be produced in two climatic versions: general and moderately cold.
• VUP are installations designed for heat flow up to 500 kW. The design of this equipment is made of carbon or stainless steel and is designed for maximum cooling of the hot air flow. Water is used as a refrigerant in this series of devices.

• GP. The equipment of this series has some design features, thanks to which the chilled water goes through several cycles, which makes it possible to more effectively cool the air mixture from large electrical mechanisms.
• VB is a built-in cooler that is designed for a heat flow of up to 200 kW.

⇡#Bladeless fans

There are fans without blades at all. Bladeless fans from Dyson, for example, look futuristic, are completely safe, but cost a lot. At first it’s difficult to understand where the air comes from: it seems like it’s coming from nowhere. Here is a room, here is a table, here is a plastic ring - and out of nowhere on the other side of the ring there is a stream of air.

Dyson bladeless fans on a telescopic stand

It's actually quite simple. The Dyson Air Muliplier draws in air and distributes it around the perimeter of the ring, creating a low-pressure zone and drawing air into the ring. Air comes out under strong pressure from a gap around the perimeter of the ring, so thin that at first glance it is not visible.

This fan, which costs around $300, operates almost silently. By the way, this technology allows you to create not only round fans, but also in the form of other closed shapes - for example, a curved oval.

One form of bladeless fans

Why Dyson? Because James Dyson was the first to bring such a design to market. Various clones often look more modest; they are produced by SUPRA, Clever&Clean, Flextron, Orion, VES, Roward, Kitfort and others.

⇡#Modern bells and whistles

Today's fans, both tabletop and floor-standing, have more than just buttons on the body. Modern models are often equipped with remote controls that allow you to change the flow power from any corner of the room. Also, a modern fan can operate in automatic mode if it has a timer: you can set the required time interval, after which the device will turn itself off.

Fan with fumigator Globus

Other bells and whistles include built-in fumigators to protect against insects, or ionizers for air purification; The latter, by the way, are already equipped with everything possible: we recently wrote about humidifiers and air purifiers, which are also massively equipped with built-in “Chizhevsky chandeliers.”

Scarlett floor fan with sophisticated control panel

Some completely optional bells and whistles include an LCD display and a built-in electronic thermometer, the readings of which cannot be said to be very accurate, especially when the fan is running. Another not very necessary bells and whistles can be called “wind mode”: that is, when the fan blows the room not with a light stream of wind, but with “gusts”, simulating normal wind.
