— Condensing (recuperative) The general principle of condensation drying is as follows: heated air is passed through the laundry drum, captures moisture, and then enters the refrigerator, cools down, and excess moisture condenses in a special tank. The advantage of all condensing machines over air vented ones is that they are easy to install. They do not need to be connected to ventilation and can be installed in any room. On the other hand, the user needs to monitor the condensate tank and periodically drain the accumulated water. And such units are somewhat more complicated and more expensive than ventilated ones. However, recuperative dryers are the simplest and most inexpensive among condensing dryers. By the name, the role of a refrigerator in them is played by a recuperator: a heat exchanger that dumps excess heat into the outside air. The heating of the air inside is usually carried out using a heating element. Due to their availability, such machines are very popular, but they have serious drawbacks. Firstly, devices of this type have high electricity consumption. Secondly, the efficiency of their work is relatively low. Moreover, it directly depends on the temperature difference between the air outside and inside the dryer.

— Condensing (heat pump drying). The most advanced and most expensive type of condensing dryer. See above for more information on conde...nsing drying in general. Note that in models of this type, the refrigerator operates due to a heat pump — a compressor that takes excess heat from the condensation chamber and transfers it to the heater. It provides several advantages over traditional recuperative drying. One of the most noticeable is high efficiency and economy: the heat pump allows you to reuse the accumulated thermal energy, and less electricity is spent on its operation than on the constant air heating in recuperative models. In addition, drying is easier and faster, and the work speed is practically independent of outdoor conditions. And such a machine almost does not produce excess heat. The disadvantages of models with a heat pump are traditional — complexity and high cost.

— Air vented. A kind of drying in which excess moisture is blown out of the machine into the outdoor space. Compared to condensing drying, this option allows you to create simpler, cheaper and more compact units. And such models are somewhat easier to use because they do not require monitoring the water level in the condensate tank. On the other hand, installing a ventilated machine is noticeably more difficult. So, in the room where the unit is located, there must be a powerful ventilation system, otherwise, there will always be high humidity and temperature. Such a microclimate is not only harmful to people and furniture but also significantly worsens drying efficiency. If it is impossible to organize general ventilation for the room for one reason or another, one will have to make a separate air duct to remove steam from the dryer. As a result, this type of drying is considered inconvenient and extremely rare.

The maximum amount of laundry that can be loaded into the dryer; in other words, the largest weight of laundry that the machine can efficiently process in one cycle.

Capacity is usually indicated by the weight of the dry laundry. Thanks to this, when preparing the laundry for washing, you can immediately assess whether it will fit in the dryer at a time or, on the contrary, you can get by with a small drying. However, even the most modest modern dryers (and even slim ones up to 50 cm) in most cases hold 7 kg — this is comparable to loading the drum of a medium-capacity washing machine. And in the most capacious models, this figure can reach 10 – 11 kg. It is quite enough for domestic and even professional use (for example, in laundromats or laundries of hotels, etc.). However, the typical figures are drying for 8 kg and models for 9 kg of laundry. Bigger capacity is relevant for industrial equipment and is not found in consumer-level models.

Also, when choosing, note that in the specs the maximum capacity is usually indicated for linen made of cotton fabric. For other, more voluminous materials, the capacity can be noticeably less — for example, the weight limit for wool products is usually 4-5 times less than for cotton.

The number of preset drying programmes. Such programmes are often optimized for a specific type of fabric: linen, silk, synthetics, etc. The more drying programmes, the more versatile and easier the dryer is to use. However, a specific set of modes in different models may be different, and even a large variety of programmes does not guarantee that one of them will be suitable. So before buying, it is advisable to specify not only the quantity but the list of claimed programmes.

Lighting system for the internal volume of the device. It usually turns on automatically when the dryer door is opened - thus reducing the likelihood that some items (especially small and dark ones) will be forgotten in the drum.

It is an indicator signalling the filling of the tank with condensate and the need to empty it. It is used exclusively in models with a condensing type of drying (see above). The specific device and functionality of the indicator may be different: in some models, it only warns of a critical liquid level. In others, it can display the exact amount of condensate collected. However, this feature greatly simplifies the monitoring of the operation of the dryer and reduces the risk of flood and other troubles that can lead to an overflow of the tank.

Drying class describes the overall drying efficiency that the machine provides. It is denoted by a Latin letter, where A is the best efficiency, and further in decreasing order ( drying class B is inferior to class A, but exceeds class C). Naturally, higher efficiency machines cost more (ceteris paribus).

The energy consumption class shows not the actual energy consumption but the efficiency of the dryer. In other words, what part of the electricity consumed goes directly to useful work. For dryers, this parameter is especially important because such devices have high electricity consumption. As a result, models with the same capabilities but different energy efficiency classes differ markedly in terms of operating costs (in terms of electricity bills). However, more economical units themselves are more expensive. nevertheless, this difference quickly pays off.

Initially, classes were marked in Latin letters from A(the highest class) and further alphabetically. In the course of technology development, more economical levels of consumption than the original class A appeared — they are labelled as A+, A++, A+++, etc. Actually, the highest efficiency class in modern dryers is exactly A +++ ; level A — A+ can be called good, B — average, C — acceptable.

The type of control provided in the machine. Almost all modern dryers are equipped with electronic control, so the design of the control panel mainly depends on this parameter. The options here might be:

— Rotary knob + buttons. The classic option does not lose popularity these days. The rotary knob is usually responsible for selecting the programme and the buttons for controlling additional functions and settings. Such control panels are simple, inexpensive and, at the same time, quite functional. Therefore they are found in all categories of dryers — from low-cost to top.

— Rotary knob + touch controls. The combination of a rotary knob responsible for selecting the main programme and a set of touch controls that control additional parameters. Compared to the buttons described above, the touch panels have a more stylish and technological appearance; moreover, due to the absence of protruding parts, such a panel almost does not accumulate dirt and is easy to clean. At the same time, these features are generally not fundamental, while the touch controls are somewhat more complicated and expensive than buttons. Therefore, this option is found mainly among dryers of the middle and top classes.

— Touch controls. This design, on the one hand, gives the device the most accurate and advanced appearance; on the other hand, the control is not as cle...ar and intuitive as with a handle. Therefore, in its pure form, touch controls are extremely rare — only in high-end dryers.

The direction in which the door of the dryer opens.

Most users are right-handed, so from this point of view, the best option is leftward opening — the free space for loading and unloading laundry is just under the right hand. However, specifically in dryers, the rightward opening is noticeably more common. It is because such units usually complement washing machines and are most often installed side by side. And in most washers, the door opens just to the left (again, based on convenience for right-handed people). Therefore, it is most convenient to place the dryer on the right and equip it with a hatch that opens to the right — this will allow you to overload the laundry from washer to dryer with minimal effort and time. And vice versa, if the door in the washing machine opens to the right, then it is better to choose a dryer with a leftward opening and install it on the left.

Sometimes both machines are installed as a column — a dryer on top of a washing machine. In such cases, the hatches of both machines should open in one direction — this is more convenient both from the point of view of ergonomics and purely psychologically. Moreover, if the "column” adjoins the wall sideways, then the opening should also occur towards the wall; otherwise, the laundry will have to be loaded and unloaded through the space between the open hatch and the wall, which can be very inconvenient....

Note that in some dryers both opening options are claimed. It usually means that the door has a reversible mount, and the direction of opening can be chosen at your discretion. However, this feature does not hurt to clarify before buying.
