Description

Apartment house old pipe demolition and household heating system with new pipe}

The present invention relates to a heating system for each generation using demolition and new pipe construction of an apartment house, and moreover, a total of four pipes are used for supply and recovery in a manner in which heating and hot water are separated. Dismantle all and connect floor heating to each household heating exchanger with two newly constructed pipes, but each household's hot water supply is directly connected to the new piping without going through the household heating heat exchanger. The present invention relates to a heating system for each generation using old pipes for demolishing old pipes and new pipes without heat loss.

In general, apartment houses, such as apartments, have a central heating system for heating and hot water supply, which is heated by a large industrial boiler in a machine room, and supplies heating and hot water for each household through heating and hot water lines. In addition, in the case of using district heating such as cogeneration, heating and hot water supplied from the cogeneration plant are supplied for each household in the machine room to perform heating and hot water supply.

However, since water flows through pipes, long-term houses over 20 years old have to be dismantled and newly installed because the water circulation is not smooth due to the corrosion inside the pipes, but it has the disadvantage of costly to replace all four pipes.

In view of this, Korean Patent No. 1113160 continually uses hot water pipes regardless of the season to reduce internal corrosion. Therefore, the two pipes used for heating are closed and the water pipes used for hot water are heated and heated at the same time. A heating supply system and method have been proposed.

However, the hot water supply pipe has a problem that the diameter of the pipe gradually decreases by layer, so there is no problem in the supply of hot water by generation, but since the recovery pipe has a single diameter, congestion occurs during recovery. Because the recovery time of the hot water takes a lot, since the heat exchange with the hot water is not made quickly in the heat exchanger installed by generation, there was a technical problem that the heating efficiency is lowered in the cold season. In addition, in the top floor, since there is no upper generation, congestion of hot water does not occur in the supply pipe connected to the top floor, the heat exchanger of the top floor has a disadvantage in that it cannot sufficiently heat the floor because the hot water flows faster than other floors.

Conventional Patent No. 1040693 has proposed a heating and hot water supply system to improve floor heating efficiency by adding a hot water supply heat exchanger for each generation so that hot water not hot water is returned to the main heat exchanger.

However, in the case of the conventional patent, since a hot water supply heat exchanger needs to be added, the facility cost is high, and the hot water supplied from the machine room is circulated to the main heat exchanger through the hot water heat exchanger, and since the separate heat source is not supplied to the hot water heat exchanger, the total heat quantity is the same. There was a limit to increasing the efficiency. In addition, in the case of the top floor, since the water pressure is not generated due to the water head difference, the hot water supplied to the top floor passes quickly through the hot water supply heat exchanger and the main heat exchanger.

The present invention was developed in view of the conventional problems, and an object of the present invention is that a total of four pipes are used for supply and recovery in a separate heating and hot water supply system. The floor heating is connected to each household heating heat exchanger by piping, and each household's hot water supply is directly connected to the new pipe without passing through the household heating heat exchanger, thereby reducing the replacement cost by half, and the hot water heating takes place quickly, resulting in heat loss. It is to provide a heating system for each household using demolition of old pipes and unused new pipes.

To this end, the present invention dismantles two heating pipes and two hot water pipes connected to the top floor from the heating heat exchanger and the hot water heat exchanger in the machine room, and connects the newly-supply pipe and the new recovery pipe connecting the heating heat exchanger and the hot water heat exchanger in parallel to the top floor. Pipe; The new recovery pipe is provided with two inverter circulation pumps in parallel so that the operation speed is automatically controlled according to the supply temperature and the recovery temperature difference through the control unit; Generational floor heat exchanger is connected to the new generation supply pipe and the new recovery pipe, and the generation heating heat exchanger has a built-in circulating pump and forcibly dismantles the aging pipe of the old house for forced circulation of hot water to the heating distributor and heating by the new pipe. In the system, the water supply pipe is connected to the new recovery pipe in the machine room so that clean water that can be eaten in the course of circulating tap water to the new supply pipe through the heating heat exchanger and hot water heat exchange is converted into hot water; Each floor generation is provided with a new hot water supply pipe connected directly to the new supply pipe without passing through the household heating heat exchanger, so that hot water as tap water is directly supplied to the kitchen and the bathroom; The new supply pipe and the new recovery pipe are formed in the range of 60mm to 25mm in the uppermost layer at a ratio of 1: 1 per floor, so that hot water is sufficiently supplied to the high floor even if hot water is used for hot water supply from the lower floor, and the new water supply pipe is used as the amount of hot water used. Tap water is replenished with a return tube; The uppermost floor has a higher return pipe and is connected to the new supply pipe and the new recovery pipe. The diameter of the uppermost floor is 10 to 15 mm, and the opening and closing of the season is controlled through an automatic valve.

According to the present invention, all the four pipes used for the existing heating and hot water supply were removed, and the new supply pipe and the new recovery pipe had a diameter of 1: 1 for each floor so that hot water was supplied and recovered with two new pipes. The floor is heated through a generation heating heat exchanger connected to the new supply pipe, and the hot water supply of each floor is directly connected to the new supply pipe without passing through the generation heating heat exchanger to supply hot water.
Since the tap water is produced as hot water from the new supply pipe and the new recovery pipe connected to the heat exchanger of the machine room, the tap water is produced as hot water, so each generation can be directly supplied with hot water for hot water supply. Compared to the quick hot water supply. In addition, since the diameters of the supply and recovery pipes are gradually reduced from the lower floor to the higher floor, even if hot water is used as the hot water supply from the lower floor, the hot water is sufficiently supplied to the high floor. Two pipes do not lack heating and hot water supply, and especially in the top floor, the return pipe with water head difference is added, so that the hot water flowing through the top floor heating exchanger becomes cold in the cold season, so that sufficient heat exchange is possible. There is an advantage.

1 to 2, the heating system of one embodiment of the present invention relates to district heating, wherein hot water supplied from a cogeneration plant is circulated to a heating heat exchanger (10) and a hot water supply heat exchanger (11) through a heating tube and a hot water supply tube. The heating heat exchanger 10 and the hot water supply heat exchanger 11 are connected in parallel with the new supply pipe 20 and the new recovery pipe 21 as previously used. In addition, two inverter circulation pumps 12 are installed in parallel in the new recovery pipe 21, and the operation speed is automatically controlled according to the supply temperature and the recovery temperature difference through the control unit 14.

The new supply pipe 20 and the new recovery pipe 21 are removed by newly discharging two existing supply pipes and two recovery pipes, and are constructed up to the top floor through each generation. The new supply pipe 20 and the new recovery pipe 21 have the same diameter at a ratio of 1: 1 per floor, and are composed of various diameters within the range of 60 mm to the top floor of 25 mm, and these diameters are the number of households and the top floor for each floor. It depends on the height.

In addition, the heating system is applied in the same configuration for each floor generation, each generation has a generation heating heat exchanger (30) connected to the new supply pipe (20) and the new recovery pipe (21). The household heating heat exchanger (30) has a built-in circulation pump 31 is connected to the heating distributor (33) of the household to achieve a floor heating, each generation does not go through the household heating heat exchanger (30) the new supply pipe (20) ) Is directly connected to the new hot water supply pipe 22 is connected to the hot water pipe of the kitchen and toilet requiring hot water. In addition, the generation heating heat exchanger (30) is provided with a heating valve 32 is connected to the room temperature controller (36) and opened and closed the heating valve 32 according to the set temperature of each room is circulated to the heating distributor (33) Control the amount of hot water.

In addition, in the case of the uppermost floor, a return pipe 23 is added to the new supply pipe 20 and the newly recovered pipe 21 so that the diameter of the uppermost floor is smaller than that of the newly formed supply pipe 20 and the newly recovered pipe 21. As to 15mm, the automatic valve 24 which opens and closes through the said control part 14 is provided. The return pipe 23 is to receive the water pressure due to the water head difference between the generation heating heat exchanger 30 and the new supply pipe 20 on the top floor, and close the automatic valve 24 in winter by up to 90% The congestion is generated in the hot water flowing into the return pipe (23). Therefore, since the hot water flowing to the top floor generation heat exchanger (30) is combined with the hot water returned from the return pipe 23 and the new recovery pipe (21), the flow rate is slowed down so that sufficient heat exchange is made in the generation heat exchanger (30). Heating is done efficiently.

Unexplained reference numeral 34 is a heating accumulator installed between the household heating heat exchanger 30 and the heating distributor 33 to record the heating hot water usage, 35 is a hot water supply meter installed in the new hot water supply pipe 22 to record the hot water consumption , 37 is a heating expansion tank, 13 is connected to the new recovery pipe 21, a water supply pipe for supplying supplemental water according to the use of hot water, 15 is a safety valve.

The heating system of one embodiment of the present invention configured as described above is to remove two existing heating pipes and two hot water supply pipes, and pipe a new supply pipe 20 and a new recovery pipe 21 from the machine room to the uppermost floor. (10) and the hot water supply heat exchanger (11) are connected in parallel with the newly installed pipes, and the new recovery pipe (21) is provided with two inverter circulation pumps (12) in parallel with the operation speed according to the hot water temperature through the control unit (14). Adjusted.

The hot water of about 100 degrees supplied from the cogeneration plant is circulated to the heating heat exchanger 10 and the hot water supply heat exchanger 11, and these heat exchangers are connected in parallel to the new supply pipe 20 and the new recovery pipe 21. In addition, the new water collection pipe 21 is connected to the water supply pipe 13 so that the tap water is circulated to the new supply pipe 20 through each heat exchanger (10) (11) is converted to hot water is converted to hot water. . Therefore, the hot water supply is faster than the indirect heating method through the conventional heat exchanger because the hot water supply pipe 22 can be directly supplied from the new hot water supply pipe 22 without passing through the household heating heat exchanger 30 in each generation, and the hot water used for the hot water supply is also used. Tap water is continuously replenished in the water supply pipe 13 as much as the quantity is heated in the heating heat exchanger 10 and the hot water supply heat exchanger 11 so that a hot water supply does not occur.
In addition, since the new supply pipe 20 and the new recovery pipe 21 are configured to have the same diameter for each floor, when the hot water is used as the hot water supply in each household, the amount of hot water recovered from the new recovery pipe 21 is reduced. Tap water is replenished in the pipe 13 so that the hot water heat-exchanged in the heat exchanger 10 and 11 is sufficiently replenished by the new supply pipe 20. It does not occur.

In addition, in the case of the uppermost floor, the flow rate of the hot water flowing to the generation heating exchanger (30) is increased when the heating valve (32) is opened in winter. At this time, the control unit 14 closes the automatic valve 24 up to 90% to slow the flow rate of the heating water flowing to the return pipe 23 as much as possible, so that the flow rate of hot water circulated to the generation heating heat exchanger 30 of the uppermost layer is Relatively slow. In other words, the hot water from the new supply pipe (20) to the top floor heating exchanger (30) is combined with the hot water circulated from the return pipe (23) to the new recovery pipe (21), in which the new recovery pipe (21) in the return pipe (23) Since the flow rate of the hot water circulated toward the side becomes slow, even if the heating valve 32 is opened to the maximum, the flow rate of the hot water in the new recovery pipe 21 is slowed down, so that the flow rate in the generation heating / heat exchanger 30 is slowed down together. Heat exchange takes place.

In addition, since the demand for floor heating is reduced in seasons or in summer, the control unit 14 opens the automatic valve 24 by about 50% so that congestion does not occur in the flow of hot water. To prevent scale from occurring.

In addition, the hot water supply of each floor is made through the new hot water supply pipe 22 directly connected to the new supply pipe 20 without passing through the generation heating heat exchanger (30). Therefore, the hot water supply is faster than the indirect heat exchange method through the generation heating heat exchanger (30), so there is little heat loss. Since the new supply pipe 20 and the new hot water supply pipe 22 are newly piped, no scale is generated inside, so even if hot water flowing through these pipes is directly used for hot water supply, it is not unsanitary.
In addition, since the diameter of the new supply pipe 20 and the new recovery pipe 21 gradually decreases from the lower floor to the higher floor, even if hot water is used as the hot water supply in the lower floor, the hot water is sufficiently supplied to the high floor. 21) There is an advantage that the heating and hot water supply is not insufficient due to the two pipes because it is rapidly circulated to 21).
Figure 3 according to another embodiment of the present invention, it shows a multi-family housing for central heating. In the case of central heating, an industrial boiler 40 is connected in series with two small capacity heat exchangers 41 and a large capacity heat exchanger 42. The small capacity heat exchanger 41 is a small capacity hot water tank 43 and a large capacity hot water tank ( 44) has the same configuration as the embodiment of the present invention except that it is connected in parallel to produce hot water.
