With the arrival of summer the increase in sales of air conditioning is increases

Those who have, guarantee that they can no longer “live without” the cold air to refresh the hot days. And they’re right. Air conditioning is a great investment, especially in high temperature regions, both in the home and in the office, where air conditioning is no longer considered a luxury to be essential. In order to know more about Air conditioning installation Geelong, you can always seek help online.

Choice of appliance

Choosing the appliance is the first step to not having any future “headaches.” Choose the model that most matches what you want and what kind of environment it will be installed. Currently, the most widely used model is known as “Split”. From the English, “split” gives the idea of ​​”division”, “break something in half”. It is smaller than the window units and quieter as well, since the part where the compressor is located responsible for the noise can be installed in another room in the laundry or on the porch.

What is a split air conditioner?

The split type air conditioner is an ambient refrigeration appliance divided into two parts. An external module, called a condenser, where the compressor is located, responsible for cooling or heating. An internal module called the Evaporator, responsible for transmitting the temperature created from the outside into the environment. The two modules are interconnected by a pipe through which passes the refrigerant. The positioning of the compressor on the outside allows the sound insulation of the appliance, since the noise is almost all outside, and it is necessary to “throw” the heat out, as it would not help if the heat returned to the inside.

Installation of air conditioning

The big problem for anyone who decided to join the air conditioning is when the house is not ready to receive it. In this case, there will be a “little reform” so that the property is prepared for the installation of air conditioning. This remodeling can vary, depending on the choice of the appliance and in which comfortable you decide to put it. In the case of new apartments and newly built houses, it is more common that you find the elements for the installation already ready. This makes it much easier, since pipes and other items do not have to be “created”, they are already part of the house’s internal architecture.

Incorrect installation of the device can influence and impair its performance, so it is advisable to hire skilled labor. There are several companies that take the technicians to the property to do the study of the size of the work and to carry out the installation of the air conditioning. What’s more, a number of tools are needed to install the air conditioner, which is probably only accessible by a technician.

Harnessing the energy of the sun with the help of advance technology

The energy of the sun is a stream of photons and is of great importance for all life on our planet. The sun ensures the existence of life on Earth, affecting the fundamental processes in the biosphere. Thanks to the sun, the seas, rivers, the surface of the planet heat up, the wind blows and so on. Man has long begun to use the light from the sun in their economic activities. But alternative energy took shape as an independent industry not so long ago. Meanwhile, solar energy plays an increasingly important role in economic activity. As the heat source, the sun has been used for a long time, and recently a large number of devices and systems for this have appeared. Today we will talk about how a person uses solar energy. In order to know more about solar power texas, you may always seek information from the internet.

Where is solar energy used?

Solar energy use is increasing annually. Not so long ago, the sun’s energy was used to heat the water in the summer cottage in a summer shower. And today, various installations are already used to heat private houses, in cooling towers. Solar panels generate electricity, which is necessary to provide energy to small villages.

Where is solar energy used?

At the moment, we can name the following areas of solar energy use, for example,

  • Aviation and space industry.
  • Heating and electricity supply of greenhouses, hangars and other outbuildings.
  • The use of solar energy in the home (heating and electrification of residential buildings).
  • Power supply of medical and sports facilities.
  • The use of solar energy to illuminate urban objects. 
  • Electrification of small settlements.

The use of the first samples of solar modules confirmed that the energy of the sun has significant advantages compared with traditional sources. The main advantages of solar systems it is almost unlimited supply, no harm to the environment, as well as free use. This list of advantages should be expanded. Stable power, since the current from the solar batteries does not have power surges.  The disadvantages include the strong dependence of work efficiency on the intensity of the sun’s rays and the lack of electricity generation at night. To solve this problem, such systems work in conjunction with batteries.

Features of the use of solar energy

Photoelectric radiation of the sun is converted into photovoltaic cells. This is a two layer structure consisting of 2 semiconductors of various types. The semiconductor at the bottom is the p type, and the top one is the n type. The first has a lack of electrons, and the second has an excess.

The principle of operation of the solar battery

The electrons of the n type semiconductor absorb solar radiation, as a result of which the electrons in it go out of orbit. The impulse force is enough to go to the p type semiconductor. As a result, a directed electron flow occurs and electricity is generated. By production of photo cells silicon is used.
