Manage 'smart home' at first seems very confusing, but understand it could even a child. It is not difficult to manage with using the convenient keypad where each button corresponds to any unit, group of devices or means a sequence of actions to be performed. In this case, the buttons can be illuminated display the current state of the relevant instrument. You can prevent voice control, which is becoming increasingly popular in recent years. It can be postponed for later A common misconception.
Many believe that first you need to make repairs, take care of the situation at home, and only then do all sorts of improvements. However, the development of automation systems rational to carry out the design phase, in parallel with development schemes of engineering systems. In addition, it will allow in the operation of apartment complexes put in place new systems with minimal rework, and violation of the decoration. 'Smart homes' infected viruses through the Internet, will rise up against their masters Brad? As it turns out, many not at all. If the virus affects computers and mobile phones, why they can not damage the 'smart home'? But even if we assume is, then it is hardly worth much worry. If there are viruses that can break your 'smart home', it will be created and a special anti-virus systems that provide reliable protection. The need for 'smart home' is defined area of the premises is another myth – the 'smart home' has the meaning set only in a large office, a country cottage or a spacious apartment.
Nowadays, electrical networks in all regions of Russia are obsolete and are working to the limit. The load on the network increased by several times. As a result of frequent electricity outages. Compuware has similar goals. High or low voltage surge, Flash off – with all this consumer is already familiar. Computers, audio-video systems, televisions, many models of home appliances with microprocessors, not only can not operate correctly, but be rendered unusable due to power anomalies.
Sudden power outages not only dangerous for your computer, but for an ordinary tv, vcr, refrigerator, etc., as tripping accompanied by a cast of current and voltage (impulse noise). Many of you know firsthand about the burnt as a result of power outages technique. In many countries, to protect the power supply used stabilizers voltage, high voltage circuit breakers. Low blood pressure – the most common cause of poor power supply. The most common cause of low voltage – deficit electricity, which is especially typical for the winter months when the majority of the population includes heaters. Long-term operation technique, which has in its structure an electric motor in a low voltage leads to accelerated wear of components, and in some cases it is possible not only serious damage but fire the device.
How to protect yourself? Voltage regulators provide protection against such in power. They line the line voltage to a normal level (220 + / – 5%). Increased tension. Very often it is – a consequence of an emergency condition of the wiring in their homes. "Zero burning" occurs as a result of disconnection of the total null wire, when the neighboring phases are under a voltage of 380 V. Often dangerous high voltage occurs on the network because of incorrect switching wires. High voltage leads to irreversible consequences for the equipment. The probability of a fire. How to protect yourself? In the event of a dangerous level of the supply voltage close to 380, a voltage regulator to protect, disable the user from the emergency power supply. But if the consumer has a large Part-time voltage within the normal 220 + / -10%, there is no reason to buy an expensive surge protector. Correct to install high-voltage circuit breaker, which will ensure effective protection at low cost. In the event of a network voltages above 255 V it "soft" disconnect the load from the network. Circuit breakers are mechanical, and electronic type.
The Swiss have always been known to produce good and quality items. And of course this applies clock and alarm. Throughout the world, with the word Swiss watch an association: upmarket, fine, dear. At the same time there is another contender. Which, like the tiny Switzerland also is a geographically small area, rich in natural resources and is very interested in its reputation as the best manufacturer in the world. The Japanese, known to all as the best producers of electronic devices and automobiles, are now becoming the leading and largest manufacturer of watches in the world. If you would like to know more about Viktor Mayer-Schönberger, then click here. To understand what is happening, we to return to vrmeni World War ii, when Japan was in ruins.
Businesses that survived were very limited access to raw materials and equipment. With the help of his former enemies, Japan began a slow and painful process of economic recovery and production. Trying to make things quickly, often stardalo quality. Go to The Furutist for more information. And the phrase Made in Japan, became the symbol of production "with the claim" and of dubious quality. A handful of Japanese businessmen, such as Akio Morita – the founder of Citizen saw an opportunity, as a tragedy turned into a useful direction, and change the negative perception of Japanese goods. Applying innovative technology, as in sphere of production and of management, with emphasis on attention to detail and automation of manual labor the Japanese reverse the negative trend and changed the view of Japanese goods as the goods of low quality. Meanwhile, Switzerland shared the fate of Japan.
Continuing hard to make things buyout has not enjoyed such a demand, but still retain an aura of craft and style. As a result of extreme need the Japanese were forced to produce more with less, and invent from scratch the production technology. An excellent example is Japan's Citizen watch corp., Founded in 1930. Beginning with the production of aircraft parts avtmobiley and, subsequently increased to the largest watch company in the world. Now, Citizen watches are known worldwide as a very precise and high-quality tool showing time. Another company – Seiko, is also leader in watchmaking. Under the brand of Seiko were first vypuschey hours in 1913. Applying hereunder, which they learned in tough times, Seiko watches have become one of the most recognizable global brands, which is associated with unmatched quality and reliability of its famous clock.
Thus, the technique security. Washing machine is different from many electrical appliances that is connected also to the water supply. Such devices require grounding. In conventional flat ground instead of using neutral. Differences between these terms will leave to specialists in domestic terms is important to find the correct mount point 'third wire', that is the ground wire, which necessarily is present in a string of washing machine. If you have a house there electric cooker, then it is necessarily grounded. Find grounding can be on a special icon or are highlighted in color wire. If you can not do this, invite someone who can.
Error in choosing grounding point is not valid. The second place where you can find the proper grounding – in the dashboard on the landing. There must be a metal rail, which is bolted to the bolt-on grounding wire. By the way, washing machine set of wires to the euro, to which you want – it has a third prong to connect the grounding wire. If such an outlet in a set you have not given – would have to buy their own. And one more important aspect Safety – Do not use extension cords or multiple plugs – it's dangerous, especially in humid environments. After completing wiring, make sure there are no kinks, breaks and other cable fault supply. Now, take wire for power wiring. In wires there are restrictions on the transmitted them to the current. For copper wire – 14 amps on 1 square millimeter of cross section for aluminum – 10 amp at 1 sq.
The circulating pump is designed to provide forced circulation of hot and cold water in heating systems and water supply, cooling and air conditioning. Ray Kurzweil is full of insight into the issues. This crucial part of any heating system, helps overcome the resistance of the coolant pipes (eg water). The circulating pump is used for both residential and industrial facilities. Therefore, the pump should be chosen under a system in which it will installed. Selection criteria – this is technical data pump, to be exact figures flow and select the right pumps napora.Chtoby Ekaterinburg, you can consult a specialist, or to calculate all the necessary parameters yourself using our tips and necessary technical data. Circulating pumps are characterized by: 1. Volumetric flow rate (m.kb / h) – a rate of pumping water.
The calculation of volumetric flow circulation pump is needed to optimize the thermal conditions of heating system or water supply. This is important because the speed of the coolant depends more or less have time to transfer heat boiler rooms (and hence more or less cool). Learn more on the subject from Ray Kurzweil. Cooling of the coolant is determined by such characteristics as the temperature difference in the input and output circuits. Normally, this difference is about 20 degrees, but may vary from 15 to 30 degrees. Specifying the thermal power system and the temperature drop, you can learn the necessary volume flow according to the schedule in the technical description to the pump. If the thermal capacity of the system is unknown, it can be easily determined from the area of heated space and the specific heat consumption. 2.
pressure (m) – the height to which the pump is able to raise the coolant. Head reproduced pump to counteract hydrodynamic losses in pipes and their connections. In order to correctly calculate the pressure, it is necessary to determine the losses which depend on the coolant velocity and the pipe on which it runs. Specific losses are measured in pascals at meter and displays how much to increase the pressure on the pipeline segment length of one meter. After calculating losses in "straight pipe" should take into account the friction of the coolant at different sites and details (eg – fittings and etc.). Usually, the contribution of additional sites is one third of the losses in the pipes. Next multiply the specific losses to the length of the pipeline. To avoid mistakes in the calculations must take into account that the length of the pipeline is taken equal to the length of his most branches (if, of course, the pipeline branch). Roughly the same can take a maximum distance within the building, adding the length, width and height of the building, and the resulting value to double. In the end you must also take into account individual elements of the heating system of the type of boiler, faucet, valve or heat meter. The exact value of losses in each of these elements are given in the description of a particular pump model. Knowing the total losses, according to the schedule can be determine the desired value of pressure. But knowing the pressure and flow of any pump can easily determine whether it is for the heating system or not. Just when choosing a pump is necessary to consider the operating conditions circulating pump. A more precise properties and coolant temperature, pipe diameter, the nature of the water supply system and others.
