According to one of the definitions, a heating system is a set of technical elements designed to receive, transfer and transfer to all heated rooms the amount of heat necessary to maintain the temperature at a given level.
What are these elements? To obtain heat, sources of various scales and levels of technical complexity can be used – from thermal power plants and nuclear power plants to wall-mounted gas boilers. As a means of transfer, piping systems filled with coolants are used – as a rule, fluids with high heat capacity and low viscosity. In most cases, ordinary water is used. Heat is transferred from the coolant directly to the atmosphere of the room through heating radiators – cast iron, steel, aluminum or bimetal. All together, as mentioned earlier, these elements represent a heating system.
Another important human need is the need for water. To satisfy it, a water supply system was created that delivers sufficient water to our homes for drinking and domestic needs. Continue reading
1. SUMMARY OF THE PROJECT
The purpose of the project is the organization of an enterprise for the production of frame-modular buildings in Yaroslavl. Modular buildings can be used as change houses, mobile office buildings, shopping pavilions, country houses, as well as full-fledged residential buildings. The advantages of these buildings are:
low cost – the use of cost-effective materials in the design allows to reduce the cost compared to wooden or stone (brick, gas-block) buildings; since the modules are manufactured according to standard designs, and the buyer orders the finished goods from the catalog, a minimum of work is carried out directly at the construction site, which also reduces the cost of construction and its time Continue reading
Our world will never be the same. Many are concerned about how to change it (certainly, for the better), including those people who cause the greatest admiration in the business world.
Some of the selected leaders were given the opportunity to post a detailed answer to the question raised by LinkedIn, a popular social networking site for business people: “What problem, innovation or event will change the world in 2013? What “big idea” are YOU betting on? ”
The results were impressive, as the leaders of completely different fields shared their views, and we have the opportunity to get acquainted with them. Continue reading
