PostHeaderIcon Understanding the importance of the renewable source of energy like the solar

The sun is an unlimited and abundant source of energy. Since 5 billion years it transforms the hydrogen atoms into Helium atoms, releasing an astronomical amount of energy. This energy is abundant and available for a very long time. In 1839, Antoine Becquerel discovered that semiconductor materials directly transform solar energy into electricity. This is called the photovoltaic effect. Nowadays, the modern green solar power usage has gained a lot of popularity. Fossil fuels are becoming scarce and the “green shift” of solar energy is revolutionizing our production and energy consumption patterns. The growing interest in this form of free and ecological energy has made it possible to set up various systems to exploit it.

The main technologies for exploiting solar energy

Passive solar energy has been exploited since the beginning of time. It consists of choosing the orientation, architecture and materials of its habitat. By making the most of these parameters, the house absorbs heat optimally. While passive solar energy has been somewhat neglected in recent decades, it is making a strong comeback with the new building standards. It would be a shame to do without a free heat source.

Solar thermal energy 

You can use solar energy to heat your water (solar water heater) or even to cook, thanks to a solar oven. Some solar panels use only solar heat, which is called solar thermal. Concretely, a coolant is heated by solar energy and this heat is fed to a hot water tank for example. The solar barbecue is meanwhile rather intended to impress your friends.

Photovoltaic solar energy is the future

Photovoltaic solar energy consists of transforming solar radiation into electricity. Here it is not the heat that is put to contribution but the energy itself of the solar radiation, that is to say the photons. It may seem a little complex at first, but it’s actually relatively simple photovoltaic panels are made up of cells. These cells are a superposition of two layers of silicon. One of the layers is negatively charged, the other positively. When a photon crosses the two layers it creates a voltage. All you have to do is connect a wire to the positive terminal and one to the negative terminal and you can use this electricity. Basically the operation is identical to that of a battery.

Photovoltaic = solar energy

When we talk about solar energy, it’s mostly about photovoltaic that we’re referring to. Indeed, when we produce electricity, we can do everything with it. This electricity can meet all the energy needs of the home. The solar water heater is convenient, but the electricity generated by a photovoltaic system can just as well feed an electric water heater. A well oriented and well insulated house is a plus, but here again photovoltaic can compensate for a lack of performance of passive solar energy. Who can do the least.

PostHeaderIcon How to Install Decorative Shutters on Vinyl Siding

Installing decorative shutters can instantly give your house a more traditional appearance. If you have vinyl siding, shutters are easy to install, but some care should be taken not to damage the siding underneath.

Although you can complete this project without help, having an extra person to hold and stabilize the shutters while drilling and to check and make sure that each shutter is level, can be very helpful. If you are installing shutters on the vinyl siding on multiple stories, you may also want a helper that will be willing to steady the ladder when you climb.

Step 1: Measure the windows and choose the appropriate shutter size.

Remember, shutters used to enclose the window glass to protect it from storms, so two shutters should completely cover a single window. Shutters that are too narrow may give your house an awkward appearance.

Step 2: Hold one shutter in place against the vinyl siding near the window.

With a pencil, mark where each screw should go on the vertical end pieces of the shutters. Plan on placing a screw about 6 inches from the top of the shutter and 6 inches from the bottom of the shutter. Shutters longer than 36 inches should have additional screws.

TIP: Space the screws so they hit just underneath the lap in the vinyl siding. This allows for more material to support the shutters and decreases the chance that you will accidentally crush the vinyl siding if you drill too vigorously.

Step 3: Place the shutter on a sawhorse and drill pilot holes through the shutters.

Step 4: Place the shutter back into place.

Check to make sure it is perfectly level with a carpenters level. Drill through the pilot holes to make a mark on the vinyl siding. Remove the shutter.

Step 5: Drill at the marks on the vinyl siding, extending the hole until you reach and drill through the exterior sheathing.

Step 6: Place the shutter back into place, lining up the two sets of pilot holes. Use screws to secure the shutter into place.

Step 7: Repeat until all of the shutters have been installed on the exterior vinyl siding. Paint the screw heads if screw caps were not provided.

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.


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.

PostHeaderIcon A better way to treat air conditioning is to saturate the air in the car with a cleaner

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.
