Description

The utility model relates to vertical heating systems with natural circulation of the coolant and can find application in heating both domestic and small industrial premises.

A known heating system with natural circulation of the coolant (Pat. RF No. 78292, publ. 20.11.2008), containing a heating medium heating device, a supplying heat pipe, an expansion tank, a heating device, a return heat pipe, a small volume boiler for a heating medium located above the heating medium heating device and having an inlet device with a float valve that provides a portioned supply of coolant to a low-volume boiler, in which the coolant is heated to a boiling point and begins to circulate towards expansion ritelnogo tank. The specified system allows you to speed up the process of circulation of the coolant and, as a result, accelerate the heating of the room. However, this system does not allow you to adjust the power of the heating system. This system is the closest to the proposed one.

The technical result, the achievement of which the claimed utility model is directed, is to provide power control of the heating system.

To achieve the specified technical result in a heating system with natural coolant circulation, comprising a heating medium heating device with heating elements, a low-volume boiler, a heat supply pipe, an expansion tank, a heating device, a return heat pipe, a device with a float valve, several small-volume boilers are additionally installed, and all boilers interconnected in series using an additional heat conduit in which direction-changing Vision coolant three-way valves, the input and output devices with flexible hoses, with the float valve device is installed in a reverse thermal conductivity. In addition, the number of low-volume boilers corresponds to the number of heating elements of the heating medium heating device; the input device is connected to the return heat pipe using a flexible hose, the output device is connected to the supply heat pipe also using a flexible hose; the input device is connected to the first low-volume boiler, the output device is connected to the last low-volume boiler, while the boilers are numbered from the input device; two three-way cranes are installed, one of which is installed between the first and second low-volume boilers, the other is installed between the second and third low-volume boilers.

Distinctive features of a heating system with natural coolant circulation are the following:

- installed several low-volume boilers that are interconnected in series using an additional heat conduit;

- the number of boilers corresponds to the number of heating elements of the heating device;

- in the heat conduit that connects the low-volume boilers to each other, three-way valves are installed to change the direction of movement of the coolant by disconnecting one or two boilers from the circulation system;

- two three-way cranes are installed, one of them is installed between the first and second boilers, the other is between the second and third boilers, while the countdown is from the input device.

Due to the presence of these signs, it is possible to control the power of the heating system by changing the number of low-volume boilers involved in the circulation of the coolant in the heating system.

The proposed heating system with natural circulation of the coolant is illustrated by the drawings presented in figures 1-4.

Figure 1 presents a schematic diagram of the system, figure 2 is a diagram of the circulation of the coolant with four boilers, figure 3 is the same with two boilers, figure 4 is the same with three boilers.

The heating system with natural coolant circulation is vertical and includes a heating device 1 with heating elements 2, low-volume boilers 3, 4, 5, 6, an input device 7 with a flexible hose 8, a supply pipe 9, an expansion tank 10, a heating device 11, a return heat pipe 12, a device 13 with a float valve installed in the return heat pipe 12, an output device 14 with a flexible hose 15 (Figs. 1, 2). A device 13 is installed in front of the input device 7. On the heating elements 2 of the heating device 1, low-volume boilers 3, 4, 5, 6 are installed. Low-volume boilers 3, 4, 5, 6 are connected to each other in series using a heat pipe 16 (Figs. 2, 3, 4). In the heat pipe 16, three-way valves 17, 18 are installed (Figs. 1, 2, 3, 4). Moreover, one crane 17 is installed between boilers 3 and 4, i.e. first and second, another crane 18 - between boilers 4 and 5, i.e. the second and third boilers, the readout is from the input device 7 (Fig.2, 3, 4). The first low-volume boiler 3 is connected via an input device 7 using a flexible hose 8 with a return heat pipe 12 through a threaded connection 20. The last small-volume boiler 6 is connected through a device 14 using a flexible hose 15 with a supply heat pipe 9 through a threaded connection 19. The device 13 with a float the valve is installed in the return heat pipe 12 in front of the device 7 for entering the first boiler 3 and is intended for portioned supply of the coolant. The output device 14 and the input device 7 are threaded connections.

The work of the proposed heating system is as follows. On the heating elements 2 of the heating device 1, which can be used as an electric stove, gas stove, etc., low-volume boilers 3, 4, 5, 6 are installed, they are connected together in series using a heat conduit 16. Moreover, the number of boilers depends on the number of heating elements 2 of the heating device 1 and can be from 1 to 4. Then the boiler 3 is connected to the input device 7. The device 7 using a flexible hose 8 through a threaded connection 20 is connected to the return heat pipe 12. The boiler 6 is connected to the output device 14. Then, the output device 14 is connected to the supply heat conduit 9 via a threaded connection 19 through a threaded connection 19. A portion of the heat carrier is supplied to the low-volume boilers 3, 4, 5, 6 using the device 13 with a float valve. Water in boilers 3, 4, 5, 6 is heated from the heating elements 2 of the turned-on heating device 1, boils, and steam is generated. Steam together with the heated coolant flows through the supply heat pipe 9 to the expansion tank 10, then from the expansion tank 10 it enters the heating device 11. In the heating device 11, the heated coolant transfers its heat and through the return heat pipe 12 enters a certain portion through the device 13 with the float valve first to boiler 3, and then to the remaining boilers 4, 5, 6. In this case, all boilers work, while both three-way valves 17 and 18 are open (figure 2), the arrows show the direction of movement of the coolant. To reduce the power of the heating system using a three-way valve 18, the boiler 5 is disconnected from the heating system, then only three boilers 3, 4, 6 work, the arrows show the direction of movement of the coolant (figure 4). If it is necessary to further reduce the power of the heating system using a crane 17 block the direction of the coolant in the boilers 4, 5, and only two boilers 3 and 6 work (Fig.3). Thus regulate the power of the heating system. In addition, household appliances, such as a kettle, can be additionally placed on boilers, thereby saving heat.

A prototype of the proposed heating system has been created, its work has fully confirmed the possibility of effective regulation of the system power. According to the results of the calculations, a room with a volume of 3 × 5 × 15 m is heated in about 52 minutes, while the initial temperature in the room is 30 ° C, and the final temperature is + 20 ° C. This is a good result.
