Ventilation systems differ in many ways, including technical specifications, design features and optional filling. At the same time, the main factor determining the effectiveness of such systems is the scheme for the extraction of exhaust air, and in some cases the inflow. The most powerful and productive design will not be able to properly provide air exchange if miscalculations were initially made in the configuration of its placement. Quite an unusual solution for many is to use a hood without venting into the ventilation, the photo of which is presented below. However, it is precisely in terms of efficiency that this option may be the best in certain operating conditions of the system.
Features non-tap configuration
Although the lack of direct access of the ventilation shaft to street air seems unusual, a similar principle of operation is quite common. To understand it, one should answer the question of what are hoods called without venting in ventilation in the language of specialists? They are called recirculators - this is a common class of equipment, the action of which is based on the intake of exhaust air and its return in purified form. That is, if a conventional ventilation system updates the air environment due to street flows, then in this case the refreshing effect is ensured thanks to the operation of filters installed in the same hood.
Combined Models
Still, far from all housewives are ready to completely abandon the influx of clean air and completely remove the kitchen burnout outside. Since both systems have their own unique advantages, some manufacturers are developing hybrid models that support both functions. But there is one caveat. The fact is that one of the main advantages that hoods have in the kitchen without venting into ventilation is simplified installation. In the case of combined installations, it will not be possible to dispense with lower costs. On the other hand, the user will be able to count on the operation of the hood in different modes - both in the recirculation format and as a complete air outlet. And here it is important to note one more nuance of the operation of a flow hood. This mode of operation is not compatible with gas equipment. During its operation, the formation of reverse thrust in the duct is possible, and then there will be a risk of poisoning the residents.
Installing a hood without venting into ventilation
The advantage in the installation process is due to the fact that the inside of the communication installation is practically absent. The contractor only needs to mount an exhaust installation in the ceiling or wall surface and, if necessary, make the appropriate settings for the operating mode. Embedded type installations cause more difficulties. Users appreciate them for their compact layout and stylish appearance, but during installation such designs require additional integration of the hinged box. In addition, the hood without exhaust into the built - in type ventilation can be adjusted according to the air intake area. A variety of models designed for installation in a countertop is also popular. The advantages of such systems include the instantaneous intake of exhaust fumes directly on the work area, and the disadvantages are the reduction of the functional space.
Positive feedback on recirculation hoods
Although users do not always notice the virtues of such models in the form of a cleaning ability, this factor is the most attractive. The fact is that the filtration system provides multi-stage processing of contaminated masses and the flow of purified air. That is, if high-quality equipment is used, the efficiency of updating the air in the kitchen will be ensured. As for the visual benefits, almost all owners emphasize the lack of noise compared to traditional systems. Since the hood without venting into ventilation does not imply interaction with mines through which air flows circulate, the absence of vibrations, hum and other noise effects is understandable. The advantages of installation have already been noted. From the user's point of view, this means reducing the financial costs of installation, saving free space for other communications, and also eliminating the need for regular maintenance of the mine.
Negative reviews
Most of the negative reviews relate to poor-quality filtering systems. The advantage in the form of exhaust air purification takes place only in the case of using high-quality membrane devices with coal sorbents. By the way, regular replacement of filters is a separate inconvenience that users note. Therefore, the lack of a guarantee for high-quality air purification by the technology itself is the main drawback for which hoods are criticized without being diverted to ventilation. Reviews also note the high cost of such installations. Again, the implementation of the technical feasibility of performing the cleaning causes the complexity of the design, which leads to higher prices. True, in this segment you can find some good budget solutions.
How to choose the best option?
First of all, it is necessary to rely on the needs of the kitchen or other serviced premises in the volumes of air that should replace the spent masses. By the way, recirculation models in this regard are easier to choose, since they perform optimal updating of the environment - the user only needs to determine the time period during which there will be a complete disposal of burning and odors. The most productive models are designed for installation in places of public catering. For example, a hood without venting to the ventilation for a cafe may have an umbrella width of 120 cm. In installations for domestic use, this parameter is 60-90 cm, which is enough for efficient air processing in a medium-sized kitchen. It is also worth considering equipment with electronic systems. In this aspect, recirculation modifications are again in the lead, in which more often the adjustment of operating parameters by time intervals and remote control are also provided.
Manufacturer's Reviews
Hoods of this type are found in the lines of almost all manufacturers of kitchen appliances and ventilation systems. The most favorable reviews relate to products of brands such as Siemens, Bosch, Mile and Kaiser. In terms of combining ease of management and performance, German models are the best. But they are also the most expensive. If you need a budget option or a model from the middle price segment, then a hood without extracting ventilation from the Electrolux company can be a good solution. The models of this brand are highly appreciated by specialists for the combination of functionality and reliability during operation. In the same series, you can put some modifications from the model lines of the brands "Combustion" and "Ariston".
The nuances of operating non-exhaust hoods
From the point of view of operation, models that do not involve connecting to the main ventilation ducts are a bit more troublesome. If traditional systems are largely designed for passive use, the functional elements of non-tap-off devices are turned towards the user, who must replace the filters and maintain the operability of other system components. In addition, the hood without venting into the ventilation may include not only updating the air in the room, but also introducing useful elements into the outgoing flows. For example, it may be purification combined with processing through ionization. Similar opportunities should also be foreseen at the stage of acquisition of filters.
Conclusion
Simplification of communication support is one of the principles that many modern manufacturers are guided by. An ordinary user tries to minimize the amount of equipment in the house, therefore, household appliances are becoming more compact, multifunctional and at the same time do not lose to traditional counterparts in terms of performance. A confirmation of this trend was the spread of hoods without venting into ventilation as a more modern and technologically advanced system. The user of such equipment can rely on the need to lay special mines, which saves money. On the other hand, manufacturers of recirculation equipment offer customers a concept in which a standard and effective scheme of air outlet to the street is replaced by equipment. That is, ensuring air quality lies entirely with the filtration system. In this approach, there are not only pluses, but also disadvantages, which are more often manifested in cheap models of kitchen hoods.
