PostHeaderIcon Perfect Utility of the UV Light System

Ultraviolet lamps are special devices that create light in the ultraviolet range invisible to humans. They have a different radiation spectrum and are intended primarily for professional (industrial) applications, although there are also domestic options. Under the general name hides a number of different types of light bulbs, each of which has its own pros and cons, its own area of ‚Äč‚Äčapplication and features of use – and we will tell about them.

What does the ultraviolet lamp consist of and how

Ultraviolet sources operate on the principle of a standard fluorescent lamp, where the formation of ultraviolet radiation occurs due to the interaction of electrodes with mercury vapor. The main difference lies in the phosphor and glass. The phosphor is either not applied at all – to release all of the radiation (including dangerous UVC), or one layer is applied, which only passes through part of the spectrum – UVA or UVB. Glass is used quartz or viol, because these types of glass are not filters for UV radiation, and pass it to the maximum extent. In this case, viol glasses have an increased throughput and carefully filter out ozone, preventing it from entering the air. This property of glass was achieved thanks to the manufacturing technology: the composition of the material contains the minimum amount of additives and coloring elements that absorb the UV spectrum. With the UV light system this is really important.

The Right Use

The use of special glass in the process of creating an ultraviolet lamp is a key factor that determines the range of radiation: when the glass components change, its characteristics change, allowing you to create ultraviolet lamps with a wavelength optimal for certain purposes. For example, a disinfection lamp will be as effective as possible if the wavelength in it is 253.7 nm: ultraviolet in this case penetrates the DNA structure of microorganisms, striking them from the inside.        

Technically, the device lamp has 6 main elements that are responsible for the effective operation of the device. Among them:

  1. A tube of special glass that has the ability to transmit ultraviolet light.
  2. Tungsten electrode – it is durable and highly resistant to high temperatures. Depending on the purpose of the bulb, a certain type of tungsten electrodes is selected (their chemical composition, length and design are adjusted).
  3. Pin base of metal or refractory plastic. Located on both sides of the lamp, equipped with a metal rim for a strong connection with the tube.
  4. Molybdenum filaments – are responsible for the current conductivity and the tightness of the flask, since they have a thermal coefficient almost equal to that of glass.
  5. Phosphor layer – is applied on the inside of the bulb and regulates the density of ultraviolet radiation.
  6. Reflex coating – a special compound that can contain certain types of light bulbs (for example, for a tanning bed). It is a reflective layer for ultraviolet concentration: a flask without a reflector is usually transparent, with a reflector – vice versa.

What are UV lamps?

A UV lamp is produced with a different bulb shape – from a compact twisted light bulb to typical fluorescent tubes (so they can look quite different), and classify such devices according to several defining features:

Main types

Compact fluorescent

These lamps produce relatively few species, but they are very easy to use.

Linear fluorescent (fluorescent)

This is the main technology in production – there are a huge number of options available in length, power, and spectrum and base. So much so that there are firms that specializes only in linear ultraviolet lamps.

Metal halide

Ultraviolet radiation is often not the main spectrum, but a side spectrum, simply because of the latitude of the spectrum of the glow of the lamp.

LED

This technology has been developing over the last 10 years, but it did not reach the level of production at which such lamps could replace other technologies for producing ultraviolet radiation.

Fine opportunities are there when it actually comes to Air Conditioning. You can actually come up within your options for the perfect air conditioning, but for that you will need to have a proper detail regarding the repair persons. If you need the machine to run for a long time, then it is a very important matter.

In service, ozone generators are the most commonly used for this purpose, which are placed in the vehicle and then the internal circulation is turned on at full power. Ozone penetrates all places and destroys unwanted microorganisms. Spray cleaning sprays are used in the same way, with which you can perform regular maintenance in exactly the same quality as a service workshop at home. In order to know more about Air conditioning repairs Geelong, you can always seek online help.An important change for the cleanliness and safety of air conditioning is also the regular replacement of the cabin filter, which most people change every two years  however, it is advisable to change once a year (again ideally before the season) and always with every disinfection of air conditioning! Without changing the cabin filter, the whole disinfection is virtually useless.

Air Conditioning Service and how It Works?

We recommend regular air conditioning service every two years, ideally before every summer season. It is also necessary to contact the service if you suspect that the car is cold or not cooling at all. In this case, it is not good to delay the visit because certain types of cars (such as Octavia 2 and 3 generation, Superb etc.) are in a state where there is no refrigerant in the circuit and the air conditioning compressor is very fast and the repair fixes the amount of ten thousand crowns.

Be aware while servicing as they will completely clean and disinfect the system

In the service, they will not only clean and disinfect the entire system (be aware of two different actions as described above), but they can also test whether everything is perfectly sealing. The leaky cooling medium runs out of leaks and if it is not enough in the system, the air conditioning does not work at 100%.During maintenance, the refrigerant is drained, recycled and returned to the correct amount. Usually about 100 grams of refrigerant is added. With the refrigerant, it also sucks on the part of the oil flowing through it and the whole airconditioning system is blotted out. This extraction oil must be replaced with the same amount of new oil when filling the system with coolant and add about 10 ml extra.As the refrigerant is sucked back and recharged, the vacuum system is still being vacuumed in the air conditioning for a certain amount of time (at least 20 minutes) to create a vacuum that forces all the humidity out of the system.
