Air disinfection: technical characteristics and operating principle

Creation of a favorable microclimate in the house is possible only under condition of using special climatic equipment. Along with the systems for regulating the temperature regime, there are entire groups of devices whose operation is aimed at cleaning and humidifying the air environment. There are also special devices for ozonation, washing and filtration. In this context, the air disinfector can be considered as the most effective option for achieving optimal hygienic parameters of the microclimate in the room. As a rule, such equipment is oriented to home use, therefore manufacturers take into account also design and ergonomic qualities in models.

Main technical characteristics

The main operating parameter of such equipment is power. On average, it is 10-15 W, which allows you to serve rooms up to 20 m2. Also, the power potential of the installation affects the productivity, which is expressed in the volume of air purified per hour. For example, an air disinfector with a power of 15 W ensures the efficiency of about 120 m3 / h. However, this value may depend on the volume of the receiver. For medium-sized rooms it is sufficient to provide a capacity of 2-2.5 liters. With regard to size and weight, these indicators vary greatly and depend on the operating principle, design features and design. If we talk about standard designs, the mass of the device rarely exceeds 10 kg, and the dimensions usually correspond to the parameters of a small mobile air conditioner.

Types of disinfectants

There are several classifications that segment this product. From the point of view of the consumer, the main feature of the separation of models is the purpose. For household needs, a home air disinfector has been designed, with convenient controls, small dimensions and modest performance.

Another type is represented by medical models. It should be noted that the very origin of the device was due to the needs of health care, and later there were also home analogues. The main difference between these devices is the efficiency of the cleaning function. In the traditional version, the air disinfector is calculated to achieve the maximum preventative effect. To provide such an effect helps ultraviolet radiation, which is unsafe from the point of view of home use, but is allowed in specialized institutions.

The principle of operation of ultraviolet models

The operation of the device is provided by special bactericidal lamps, which dissipate ultraviolet streams. As a result of irradiation, optimal air quality parameters are achieved. In this case, irradiation can have different characteristics, the main of which is the wavelength - in the corridor from 205 to 315 nm. For example, lamps with radiation in 254 nm can destroy about 91% of microorganisms in the air. The peak of the bactericidal effectiveness of the radiators is 265 nm. When buying the device, it should be noted that the ultraviolet air disinfector is usually sold without a lamp. It is because of the wide spectrum of radiation characteristics that there are no plants operating only with lamps of the same scattering length. Sources of ultraviolet waves should be purchased separately, taking into account the parameters of the socle and compatibility with the operating characteristics of the installation.

Principle of photocatalytic disinfection

Devices of this type are mainly intended for use in living quarters. This is a relatively new device that is highly environmentally friendly and safe for users. In comparison with cleaners, whose work is based on UV radiation, the photocatalytic air disinfecter acts on the principles of oxidation of substances on the surfaces of the catalyst. In this case, also used ultraviolet radiation, then in the so-called soft spectrum. The reaction safely passes at room temperature, while toxic elements do not accumulate on the filters.

Additional option

Climatic equipment in modern versions is usually supplied with electronic systems. This is a useful addition that will allow you to configure the parameters of work at a distance or with the use of automatic modes. But, in addition to ergonomics, it is important to take into account the immediate functions of the device, including ionization capabilities, humidification and ozonization. A multi-functional decontamination-air purifier can also provide protection against fine dust. Particular attention should be paid to filtration technologies. The newest models are often supplied with HEPA filters, water and photocatalytic cleaning elements. Especially for the disposal of unpleasant odors, smoke and gas, ozonizing systems are also used. As for direct disinfection, this function is best handled by photocatalytic filtration components.

Manufacturers

Almost every manufacturer of air conditioning units contains a series of air purifiers in the model line. But there are specialized manufacturers that manufacture disinfectants for household use. Among them, we can distinguish models EcoBox and Daikin, which are presented in modifications for large rooms and for small apartments. Also, many successful and inexpensive models in the line Air Comfort. Among domestic products, the most popular air disinfectant is the "Tion" in the modification B120. A special feature of this model is the wide possibilities for ventilation of premises, as well as the function of heating air, which is especially important in the winter.

How to choose the best option?

Before buying a decontamination device, it is important to determine the installation site, calculate the service area and the time modes of operation. The productivity should be correlated with the volume of air. The fact is that the installation of a large-sized device in a small room is unprofitable from the energy saving point. Although, according to users, in some cases, exceeding the power relative to the optimal queries at times reduces the time for performing the basic functions. It has already been noted that the lamp emitter is purchased separately, so it should be presented with separate requirements. If an air disinfector is chosen for the home, the duration of its continuous operation can be small - from a few minutes to an hour. However, when servicing office and industrial premises, the lamp should maintain the operating mode for 7-8 hours.

Conclusion

Modern apartments and private houses are often burdened with an excessive amount of home appliances. The popularization of a healthy lifestyle and devices to create a favorable microclimate has added to traditional devices a wide range of climate facilities. In this case, not always they justify their acquisition, since for the same cleaning there is enough quality ventilation. Nevertheless, the air disinfector is allocated on the general background of such devices in that it is oriented towards the solution of specific tasks in achieving the best sanitary and hygienic indices. An alternative that naturally removes dangerous bacteriological elements simply does not exist. Another thing is that the device itself can pose a certain threat to a healthy microclimate, but with the right choice and it can be avoided.
