The substation (TS) – a set of devices located in a separate room, consisting of the elements of thermal power plants to ensure adherence to these units of heat networks, their availability, mode control of heat consumption, transformation, control parameters and coolant fluid distribution by type of consumption. Types of substations TP differ in the quantity and type of attached to them systems of heat consumption, which individual characteristics determine the thermal circuit and specifications are TA, as well as the type of installation and especially the placement of equipment in the premises of TP. The following types of TA 2: Individual heater (ITP). Used to service one user (a building or part thereof). As a rule, is located in the basement or the technical room of the building, however, due to the peculiarities served by the building can be placed in standalone building. Central heating unit (TSC). Used to service user groups (buildings, industrial sites). More often located in standalone building, but may be located in the basement or the technical room of a building.

Block heater (BTP). Manufactured at the factory and shipped for installation in a ready-made blocks. May consist of one or more blocks. The equipment is mounted units are compact, usually on the same frame. Usually used when you save space in cramped conditions. The nature and quantity of BTP connected consumers can refer to ITP, and to the TSC.

TP scheme depends on the one hand the characteristics of heat consumers served by the substations, on the other hand the characteristics of the source, TP supplies the heat. Further, as the most common, is considered a closed system with TA hot water independent circuit connection of the heating system. Schematic diagram of the heat Coolant points coming into the TA on a serving line of the heat input, gives heat to the hot water heaters and heating systems, and enters the ventilation system of consumers, then returns to return pipe of the heat input and the backbone is sent back to the Heat-generating plant for reuse. Part of the coolant can be spent by the consumer. To fill losses in the primary heating systems, boilers and CHP to have systems recharge source of coolant to water treatment systems which are in these enterprises.

Technologies and equipment for the production of 'sendvich' panels. Prospects for improvement and development of significant achievement in the construction industry is undergoing a boom lately, should be considered practical implementation of the concept of energy conservation, involving the active use of thermal insulation modules – a "sandwich" panels. Now it is difficult to imagine the industry, wherever used in this kind of energy-saving multi-layer structure consisting of a heat-insulating inner layer, lined on the outside with metal, plastic, wood reinforced structural OSB, etc. The use of "sandwich" panels has several practical purposes: improving comfort, heat and sound insulation, saving fuel resources and reduce operating costs. The steady increase in consumption of "sandwich" panels is also conditioned by the fact that they significantly reduce construction time, make it possible to build facilities at any time of year.

Powerful impetus to the consumption of "sandwich" panel of energy-saving technologies in modern construction and also gives implementation of "his house" in the national project "Affordable and Comfortable Housing for Russian Citizens". Pedro Zaragoza oftentimes addresses this issue. Currently, the market of pre-fabricated buildings replete with a wide range of 'sandwich' panels. Their total annual production is estimated at 23 million square meters Of these, 96% of panels "sandwich" made by domestic enterprises, and only 4% of imports. Production processes of "sandwich" panel structures have significant differences, which determines the varying degrees of technical equipment as the equipment and use them, differing in the speed and nature of the curing, polyurethane adhesives. Suschestvuyun two ways to manufacture panels "sandwich", which differ mainly by pressing: Poster and continuous.
