Tuesday, November 29th, 2011

Air conditioning has become a vital and integral part of human existence, because without it, it is impossible to organize a comfortable climate in summer time as office buildings, and residential and industrial. Two major problems which are solved conditioning and ventilation system: 1. The necessary parameters for a comfortable microclimate people The minimum need one person to fresh air at 20 cubic meters / hour (in accordance with SNIP). To create a normal state of health and comfort of one person should be up to 60 cubic meters / hour of fresh air at 50% relative humidity and air exchange rate of 0.5 m / sec in the room. In addition, depending on the type of premises must take into account the multiplicity of air exchange rate, which is regulated by SNP. 2. The working environment to ensure given the technical process to ensure the basic parameters of conditioning and ventilation systems and to avoid premature failure, you should regularly perform diagnostic research, which may give again only major HVAC companies – because of the high cost of diagnostic equipment used. Speaking about service, it is worth mentioning warranty repairs.

Provides it directly to the manufacturer, and only through authorized by the operator which as a rule, the distributor of this brand. The warranty period for HVAC equipment in licenses and certificates of all relevant agencies, but also on the list of services provided by the vendor. The list must include warranty and service. The presence of these points – evidence for the professionalism of the company. You should also ask the company experiences when and where the company to perform certain work.

It is worth to contact with former clients of the operator to know them opinion about the quality of services provided. The quality of the air-conditioning systems not only provide installation and subsequent maintenance. Before you install air conditioning or ventilation system equipment to choose the right. Remember that a manager must pre-planner to visit the room where you plan to condition and to calculate the necessary power equipment. In such a calculation is consider not only the floor area (roughly speaking – on the 1 square meter to 100 watts of power), but its filling various kinds of furniture and equipment. Agree between the gym and conference room, and even more so – technological premises of the same size there is a difference. Typically, the air conditioner specifications are for specific operating conditions corresponding to different standards. With their non-compliance varies according to the parameters and performance conditioning. Therefore, literate account of heat into the room revenue is required when buying foreign currency, and such a calculation is able to perform only specialist. To do this, consider glazing and orientation of external walls, internal walls of the area adjacent to nekonditsioniruemymi premises, the type and area of flooring and ceiling, to calculate the heat-income of ventilation, appliances, computers, servers, cooling equipment, as well as the occupants of people, also takes into account the number and size of doorways. And each of these items considered separately.

Internet V Runet

Friday, November 11th, 2011

First, a little theory. Internet is a global information network, designed to facilitate communication between people, to give the ability to communicate at a distance, share photos and so on. Runet- part of the World Wide Web, covers the domain ending. ru, that is, sites that belong to Russia, although in reality, the "Russian" servers, could be anywhere in the world, but on a different domain can be quite ruskoyazychnye server. That is the first major difference is that ooiao – this is just one of many parts of the Internet, which lives and develops in its own way. Since the Internet is the combined work of people of all states, over the webcams are only the population of Russia, as well as some foreign nationals. Although ooiao and copies some Western sites (many information and entertainment resources), it develops quite differently.

And although the share of its World Wide Web is rather small, he goes his own way. That is the second difference, a very different human resources. The third difference is that the Internet and ooiao at the beginning of the birth of the information age (from thousands nine hundred and fiftieth year of nineteen hundred and ninety year) have evolved quite differently and apart from each other. If the World Wide Web can be regarded as transfer of the first letters at a distance in America (Nineteen shestidesyat fifth year) is a national network of Russian (then USSR), it can be assumed to launch the first satellite (one thousand nine hundred shestidesyat fifth year), then what great hurt our western neighbors and spodvigli them on the development of the Internet. And up to one thousand nine hundred ninth year, these two networks is almost touching, while at the same World Wide Web captures much of the world. And if we paid more attention to our national network, if it got a lot of publicity, it had every chance to become as powerful and have equal rights to the Internet.

The fourth difference is the language network. If the Internet as a global spider web, primary language – English, then Runet, like Russia's national domain – Russian. The fifth difference is included in the Runet and the Internet to scale their networks. If the national Russian domain is combined local area networks, such as sinks, then the World Wide Web is the entire domain, like the same ru, uk, com, and other larger parts. In a word, the difference in size and importance. Oh, and sixth, I quite complete, the distinction is that ooiao affects not only the Internet, and for example, more and Fidonet, free amateur network, as well as many corporate networks, and if by webcams understand users.
