Description

Description of the invention

The useful model refers to heating equipment and can be used for heating and hot 2 water supply of apartments in residential buildings using an autonomous heat source.

Water heating systems are distinguished by the method of water circulation (with natural and artificial), by the location of the distribution mains (with upper or lower distribution), by the method of laying the distribution mains to the heating risers (dead-end and with accompanying water movement), by the construction of the risers and the scheme connecting to them heating devices (two-pipe and one-pipe). 70 Systems with natural water circulation (two-pipe and one-pipe) are allowed in houses with an individual boiler room with a radius of action up to ЗОm and a vertical distance from the center of the device on the first floor to the center of the boiler at least Zm. Water systems with natural circulation are performed only with dead-end branching of mains. In low-rise residential buildings, you can use an apartment water heating system with upper and lower distribution and natural circulation. In other cases, water heating is arranged with 72 pump-induced water circulation.

There is a known apartment heating system, which contains supply and return pipelines connected to the heating pipelines of the heating network, heating devices, a shut-off valve and a control valve (A.S. 987302, according to class E2403/02, BI 1, 1983, USSR).

The well-known apartment heating system does not have an autonomous heat source and water heater.

A well-known apartment heating system, which includes a heating boiler, a heat exchanger for hot water supply, supplied with an expansion tank, a four-way regulating and distributing valve with an electric drive and a pump. Moreover, the boiler and the four-way valve are electrically connected to the sensors and control equipment of automation (Y.S. Davydov et al. Novye sistem! avtomatizatii otopitelnykh stradzhy. M.:

Stroyizdat, 1990, p. 138, fig. 47).

The well-known apartment-by-apartment heating system is complex in design, contains a significant number of elements in automation and heat-converting devices.

A gas stove-boiler is known, which contains a casing, a burner chamber, a chimney, a water heating tank, an oven, a heat pipe and gas burners, and the cabinet and pipe are shielded by water heating pipes in the form of a coil (AS 506731, according to class E24С3/00, BY 10, 1976, USSR. Fr

The well-known gas stove-boiler is not equipped with automatic safety and regulation devices. Gee)

The closest technical solution to the proposed system is a system of apartment water heating, which contains a heating boiler, direct and return pipelines, between which heating devices, an expansion tank and a pump are installed on the risers (Y.N. Berkman et al. Handbook of foreman-plumbing. Kyiv: su

Budivelnyk, 1975, p. 197, fig. 60). 3о A significant drawback of this system is the absence of a pump outlet line and the use of fittings with significant hydraulic resistance, which significantly impairs the operation of the system.

The task of the proposed useful model is to expand the functionality due to the introduction of additional elements into the system and the relationship between them. This is achieved by the fact that the heating system, which contains a water heating boiler, has direct and return pipelines, while a Z 50 ball valve, heating devices and a pump are placed on the return pipeline, a bypass pipeline is placed on the return pipeline, and the pump is installed on return pipeline, and the return pipeline has two ball valves, one of which is installed before the pump, and the other after it. The bypass pipeline can also be installed on a straight pipeline. The boiler can be heated by gas, electricity, fuel oil, etc.

Figure 1 shows a schematic diagram of heating with gas heating when installing a bypass pipeline on the return pipeline. - Figure 2 shows node 1 of Figure 1. The system includes a water heating boiler 1, connected to it through nozzles 2 and C, a direct pipeline 4 and a return pipeline 5, heating devices 6, an expansion tank 7, an air intake 8 and a pump 9. Boiler 1 and connected by a pipeline 10 through a tap 11 with a pipeline hot water supply 12. Boiler 1 as well

Gee! 20 is connected by a pipeline 13 through a faucet 14 with a cold water supply pipeline 15. Pipeline 4 has a ball valve 16. A non-return valve 17 is installed in pipeline 5. A bypass pipeline 18 is cut into pipeline 5, which is supplied by taps 19 and 19". At the same time, taps 19 and 19' are placed on the bypass pipeline 18 in front of pump 9 and after it. .

Boiler 1 has a gas combustion device 20, burners 21 and chimney 22. Boiler 1 protection sensor 23 against water overheating 29 and two-position adjustment sensor 24 are installed in its water heating tank (not shown), electrically connected through the control panel 25 with safety automation and adjustment of the gas burning device 20. The draft control sensor 26, installed in the chimney 22, is also electrically connected through the control panel 25 to the automatic safety and regulation of the gas burning device 20.

A coarse cleaning filter 27 is installed on the return pipeline in front of the pump 9. 60 The system works as follows:

The water heating capacity of the boiler 1 and the heating system are filled with water through the expansion tank 7 with the taps 16, 17, 19, 19 open. Then the ignition device 20 is turned on. and start heating the room. After the draft in the chimney 22 stops or the water overheats above the permissible level, because the sensors 26 123 through the control panel 25 will stop the gas supply to the gas burning device 20.

To obtain hot water for household needs, when the gas combustion device 20 is working, taps 14 and 11 are opened. This action connects the cold and hot water supply systems to each other, and the water is heated in the coil (not shown in the drawing) of the water heating tank of the boiler 1. After the end of hot water intake, taps 11 and 14 are closed.

The proposed system does not need constant monitoring, because the valve 17 works in automatic mode, that is, when the pump 9 is turned off, the valve 17 opens, providing a natural circulation mode, and when the pump 9 is turned on, the valve 17 is closed and does not allow the pump to circulate in a small circle.
