Rating of the best air coolers for 2024

A heat exchanger whose task is to cool the air is called an air cooler. The best models of air coolers will be discussed below.

Installation

Before installing such equipment, it should be noted that the installation of duct coolers is carried out exclusively in a horizontal position. This position contributes to improved condensate drainage. When using water as the main substance, it is recommended that the installation be carried out in heated rooms (positive temperature). Also, manufacturers and numerous users advise using a siphon (hydraulic flap) to avoid unpleasant odors.

It should be noted that the distance to the bend must be at least the diagonal of the selected cooler model.

Connecting the air outlet and preventing it from freezing

In order to prevent irreparable from happening, during the installation process, you must adhere to some rules:

1. The liquid is drained at subzero temperatures if there is no antifreeze in its composition.
2. Climatic conditions for each of the regions are different, therefore, when choosing an anti-freeze refrigerant, its temperature must be below the designated limit.

Main parameters of selection and functionality of duct air coolers

As with the principles of other cooling devices, it is quite straightforward. Inside the device, air from the room enters forcibly (sucked in), where it comes into contact with the evaporator, or rather, its surface. The laying of such communications is carried out at the initial stage of construction. After that, the air masses are cooled to a certain temperature and distributed throughout the premises. Any material can be inside the evaporator. Often we are talking about freon, which can be found in refrigeration chambers.

However, water air coolers should not be ignored either. The main mistake when choosing a material is the lack of the proper amount of information regarding the formulations used. Freon designs are able to cool the flow faster and more efficiently. However, constructively they are somewhat more complicated. In addition, they differ significantly in cost. Freon leakage can not only harm human health, but also lead to many other unpleasant consequences.

No less important selection criteria include:

1. Ease of installation.
2. Reliability in use.
3. Low noise figure during operation.
4. If necessary, other designs can be used to help absorb noise.
5. For a short period of time, the device is capable of passing a huge amount of air through itself.
6. Compactness.
7. Possibility to install units in ventilation structures of buildings and structures.

The kit includes a drip tray and heat exchanger. The rapid air exchange ensures a regular supply of fresh air to the premises where people are. Structurally, it consists of a huge number of copper tubes, inside which the selected substance circulates. The dimensions of the device may vary depending on the capacity of the cooling device and consumer demands. The drip tray consists of plastic plates that collect condensate in a specially placed bottom tray.

Selection features

You should pay attention to the fact that high-quality step-by-step instructions will allow you to do the installation yourself (on your own). However, this is not recommended if a person does not have the necessary amount of skills and knowledge. Otherwise, the safety index of the structure will be low. The best manufacturers recommend paying special attention to some aspects when choosing a model of an industrial cooling unit.

What to look out for first	What to look out for second
Liquid and air consumption. Applicable to water coolers.	Weight of the device.
Power indicator.	Temperature conditions at the outlet.
Types of popular models. For home or industrial premises.	Indicator of fluid pressure inside the structure. Applicable only for aqueous media.

Duct options are installed in residential buildings. However, industrial designs can also be purchased if required. Thus, the building will be provided with more intensive cooling of large rooms or free spaces. Structures are of several types and are divided according to characteristics, performance and installation method (ceiling). Design and appearance will play any role only if the installation is carried out in a public place (floor), where everyone can see it. Color also has no functional load. You can get acquainted with brands and opinions of customers in one of the many online stores.

Water or Freon?

A feature of refrigerators with freons is the presence of compressed freons inside the heat exchanger. You don't have to do a complete disassembly during repairs. It is enough to check the tubes inside which the freon is compressed. This contributes to the start-up of the operation of the condensing equipment. Often, filler grades 22, 410 and 407 are used in the design. The main feature of such freon is the ability to cool air masses of any volume in a short time. The negative characteristics include the tendency to completely freeze.

Water structures are filled with liquid. Glycol is used as an auxiliary component. In addition to the cooling function, such an installation can dehumidify the environment. Installation is carried out in channels of rectangular and circular cross-section. In terms of efficiency, they are inferior to freon ones, but they are much more comfortable in operation. It is worth paying attention to in order not to make mistakes when choosing high-quality and reliable equipment.

Rating of quality water systems

Water structures are used in channels that have a rectangular or circular cross-section. The filling is identical to that used in popular freon models. It should be noted that it is possible to manufacture a structure according to individual measurements if the dimensions of the channels do not belong to the category of typical ones.In order to place an order, you will need to contact the brand representatives by phone or fill out the proposed electronic form.

Conclusion

Air coolers are often installed horizontally. Installation features allow you to carry out all the necessary manipulations yourself, without the involvement of professionals. However, in the absence of the necessary skills, it is recommended to seek help from a specialized company that provides guarantees for the work done.

The main thing is to monitor the temperature regime inside the system, the indicator of which should not exceed + 30 ° С. The percentage of moisture should not exceed 43%.

Before installation, it is necessary to check the place near which there should be no flammable and explosive substances. You should also not block access to the hatch and the system itself. Furniture items should be at some distance from the viewing window. The air inside the premises must be clean. The service life of the device will be significantly reduced if the premises are smoky or heavily smoked. Sticky and fibrous additives also have a negative effect on equipment life.
