Description

In the conditions of high-speed construction of multi-storey buildings, the lower floors, where finishing works are carried out, must be heated before the masonry of the entire building is completed. This results in the advantages of the installation work during the high-speed construction of a horizontal front and the expediency of using a horizontal system with two-way sequential bottom connection of radiators "from bottom to bottom."

FIG. 1 shows a diagram of the arrangement of a heating system with a lower radiator connection for an upper hot spill; in fig. 2 - the same, with the lower mountain than the spill; in fig. Z4 - radiator connection diagrams in plan.

The proposed heating system is as follows: from the heating boiler / pipe 2 rises to the expansion tank 3, from where pipes 4 descend; They are connected to horizontal floor pipelines with radiators 5 included in them with an inlet and outlet of water from below. The horizontal pipes are connected to the boiler by means of a pipe 6 with a circulation pump 7.

The proposed heating system is applied with the top (Fig. 1) or the bottom (Fig. 2) hot spill. The air removal from the system is provided for centralized (through a flow dilator or air collector with a plunger at the bottom spill) and local at each radiator, with the help of: simple air vent plugs, buttons or plungers. The path of water in the system is shown in the drawing by arrows. The radiators 5 are connected to the water lines either by means of a standard duck of the 8th and straight section (Fig. 3), or directly by means of a standard tow (Fig. 4).

In the bottom-down (Fig. 2) system, designed for school buildings, universities, dormitories, barracks, laundries, baths, cinemas, theaters, greenhouses and industrial buildings, individual adjustment of heat transfer from heating devices is excluded, which seems to be rational from economic points of view. New in this system remains the economically advantageous sequential lower connection of column radiators to one common horizontal branch.

The proposed system aims to achieve a reduction in the total cost of the device compared to conventional vertical systems, a reduction in the amount of metal, and lower labor costs for installers due to the simplicity of the connections and the horizontal scheme.

Subject matter

Water on the central heating system, characterized in that the column radiators are turned on "from bottom to bottom."
