Infrared Heaters

Thus, infrared heaters – heaters is that transfer heat to the surrounding objects by means of infrared rays. The surface of objects absorb radiation, heat and then transfer heat to the air. This principle of operation allows significant savings in energy consumption compared with other types of heating systems, where most of the heat goes to heating Ceiling space. Also worth noting, infrared otolenie – this is the only class of heating, which allows you to warm up a point, ie Not fully premises, but only those areas that are required. Moreover, the heat from infrared heaters is felt almost immediately after turning on and little or no loss up to the heated surfaces, which also affects the cost of energy consumption. Infrared carbon heaters have a very broad scope of use – residential, commercial area, shops, gyms and other places of mass attendance, production facilities and warehouses, showrooms, and many others. Along the length of the radiated waves infrarkanye heaters are divided into short-, long wave and medium-wave. It follows from the categories, their main difference is the wavelength, which in turn depends on the temperature of the heated body – the higher the temperature, the shorter the wavelength, and higher intensity.

Long-wave is also called the dark, for the richine that they do not emit light, even when their operating temperature of 300-400 C. Medium-wave work at a maximum temperature of 800 C and emit a soft light, therefore they are called light or white. Infrared heaters are also classified by type of energy consumed by electric, gas and diesel. The researchers note that gas and diesel heaters they are more economical efficiency is 85-92. But they reduce the level of oxygen in the air and reduce humidity in the air. For these reasons, gas and diesel infrared heaters are not recommended use in a residential area. According to the type of heating element infrared heaters are classified by halogen, carbon, and ceramic tenovye infrared heaters. The main heating element halogen infrared heaters is a halogen lamp that emits light in the main stream in the infrared spectrum.

The only disadvantage of halogen heaters is that due to a fall or violent impact vacuum tube can be broken. The infrared heater carboxylic main heating element consists of a carbon-carbon fiber, which is placed in a glass tube. The most important advantage of infrared carbon instruments is lower power consumption compared to other infrared devices heating at about 2-2.5. Among the disadvantages – they can not dry things when reaching 98 C inside the instrument this will protect from overheating. If you fall or bounce probable risk of breaking the quartz tube. In the manufacture of the heating element in the ceramic infrared heater used ceramic tiles, collected in a single reflector. This class of heating systems is based on flameless combustion of the gas-air mixture inside the tile, which it is heated to 850-900? C. After that, heat is transferred surrounding objects, surfaces and people. And infrared heating devices are divided on the place of assembly. On this factor, isolated heaters ceiling, wall, portable floor. Summing up the above, leading advantages of this class of systems of heating are: they do not alter the percentage of moisture in the air and the saturation of oxygen, economical in terms of energy consumption does not cause air circulation in the room and avoiding the draft. In addition, they are easy to install, fast warm up the room, plus everything are the only heaters allows for efficient heating point.

Automatic Water Pumping Systems

First – pump automatic watering systems should provide the pressure on entering the pipeline system approximately equal to 4.5 atmospheres – only under such pressure can ensure high quality irrigation watering the entire area. The second – the pump for the automatic watering must be equipped with automatic controls for self-activation and deactivation. Third – if the pump is automatic watering system is located outside the premises ottaplivaemogo, it should simply be mounted and dismounted. The fourth – the price of the pump should vary within reasonable limits. Thus, we concluded that the best option for the system avtopoliva site can only be a pumping station. What is a pump station? This technologically fairly complex device consisting of a self-priming pump, membrane pressure tank and automatic controller. That the pump is designed to lift water from a clear to everyone, which also need other components? Pressure vessel is required to maintain a constant pressure, as it is used as an additional water tank, which eliminates the frequent inclusion of the pump with a short work, such as hand washing or set into a glass of water. Automation unit allows connection and disconnection of the pump when you start the next cycle of irrigation.

In practice, this is as follows, remote control system provides automatic watering solenoid valve. The pressure in the automatic watering system is falling sharply. When the pressure drops below 2 bar pressure and the relay is switched on the pump. The pumping unit is switched on and connected via pipeline starts to pump water from the source system avtopoliva, while maintaining the necessary systems for automatic watering pressure. Also, a pumping station can be automatically activated by the sensor flow at a rate of more than 1.2 l / min, with a decrease in consumption less than 1.2 l / min work station stops, thereby minimizing the frequent inclusion of off-pump motor, which is accompanied by a sharp surge overload. As noted in other articles of our site, the pump should be protected from the so-called "dry run". This situation usually occurs in water sources, which are very small debit (debit of water source – the amount of water that filled the well or wells at a time).

In the absence of water in the pump casing is no additional cooling, which leads to failure of bearings, mechanical seal, and, therefore, the motor pump. In pumping stations for the automatic watering system provided a constructive flow switch, which is when a "dry run" automatically suspend the operation of the pump. Also provide an access enable or disable the motor thermal overload pumping station or clogged. If there has been clogging the pump and periodically triggered protection the pump will be re-run every 30 minutes. For quality parts and protection of workers indoor unit pump when disconnecting from the water hammer, pump unit for automatic watering system fitted with a reflux valve.

After World War

Even if we use a moderate amount of sugar sold by weight, it does not mean that so we do not regard this issue as well as sugars and sweeteners present in soft drinks chewing gum, sausages, yoghurt, confectionery. The presence of sugar in many products, sometimes even hard to guess. Stevia Honey – a healer and a threat … sugar magnates in Japan long ago replaced sugar natural sweetener – Stevia honey. After World War II, when scientists of the country looking for plants that would help bring radionuclides, stevia began to explore and grow in greenhouses.

Scientists have discovered so many useful properties in the grass, now that 90% of the world's stevia grown in Japan is buying up and adds it to the 50% of product names. It's not just ice cream, candy, yogurt, and pickles, sauces, teas, beverages, toothpaste. Production of synthetic sweeteners in the country is prohibited. According to medical scientists precisely because stevia products, life expectancy in the Land of the Rising Sun is 90 years. Because of the tragedy Hiroshima and Nagasaki in Japan, stevia is declared national treasure, its removal from the country is prohibited. Homeland Stevia – northern Paraguay on the border with Brazil. The indigenous peoples of America Adolescent use of more than a thousand years.

Spanish conquistadors in the 18th century noticed that the natives used tea mate with stevia as a bracing means and in any distress. In the 30s of last century in the Soviet Union, this plant has delivered Academician Vavilov, geneticist scientist. Vavilov pointed to the unique properties of herbs to restore the disturbed metabolic processes in the body, increase energy levels, delay the aging process, protect against the harmful effects of environmental environment, to harmonize all the systems of the body, while keeping intensely sweet taste, similar in taste to sugar. But seriously engaged in research on plants only in the second half of the 20th century.
