Description

Apartment housing integrated piping control system

The present invention relates to an integrated piping control system for an apartment house, which controls the number of rotations of a pump according to the pressure difference between a supply pipe and a return pipe, and allows preliminary hot water maintaining a set temperature to be always on standby, and when hot water is not used, It relates to an apartment house integrated piping control system that prevents the temperature of the flowing hot water from falling by allowing the hot water to circulate, and blocks the noise in the pipe of the return water.

In general, apartment buildings such as apartment houses use district heating heat sources such as central heating systems or cogeneration for heating and hot water supply. Heating and hot water supply are provided for each household through the system.

Conventionally, two pipes for supply and return are installed and used as four pipes forming a group so that hot water supply and heating are performed separately. In the case of renovation and repair, the heating pipe itself was buried or located inside the building, so there was a very difficult problem for the worker.

Recently, in order to solve the above problem, a technology has been disclosed that allows hot water supply and heating through only two pipes (supply pipe and return pipe).

In Korean Patent Registration No. 10-2013197, two heating pipes and two hot water supply pipes connected from the heating heat exchanger and hot water supply heat exchanger in the machine room to the top floor are all removed, and a new supply pipe and a new supply pipe connecting the heating heat exchanger and hot water heat exchanger in parallel pipe up to the top floor; two inverter circulation pumps are installed in parallel in the new return pipe so that the operating speed is automatically controlled according to the difference between the supply temperature and the return temperature through the control unit; A household heating heat exchanger connected to the new supply pipe and a new return pipe is provided in each floor household. The household heating heat exchanger has a built-in circulation pump to forcibly circulate hot water to the heating distributor. In the system, a water supply pipe is connected to the new return pipe on the machine room side, so that clean edible water is converted into hot water in the process of circulating tap water to the new supply pipe through the heating heat exchanger and hot water supply heat exchange; Each floor household is provided with a new hot water supply pipe directly connected to the new supply pipe without going through the household heating heat exchanger, so that hot water, which is tap water, is directly supplied to the kitchen and bathroom; The new supply pipe and the new return pipe are formed in a diameter range of 60 mm from the lowest layer to 25 mm for the top layer at a ratio of 1:1 for each floor, so that even if hot water is used as hot water from the lower floor, the hot water is sufficiently supplied to the upper floor, and the new number of times from the water supply pipe by the amount of hot water tap water is replenished by tube; The top floor has a higher return pipe and is connected to the new supply pipe and the new return pipe, the diameter of which is 10 to 15 mm, and the opening and closing of the apartment house is characterized in that the opening and closing is controlled according to the season through an automatic valve. And a heating system for each household using a new pipe is disclosed.

However, the above technology applies two pipes to provide hot water supply and heating to households by floor. It is possible to control the flow of circulating water by selectively opening the automatic valve according to Because the electric wire line for controlling the system must be connected to the central monitoring panel (machine room), there are many problems in terms of increased construction cost and management difficulties.

In addition, when there is no use of hot water in each household, the flow of hot water cannot be made, so there is a problem in that the pump is overloaded due to the differential pressure between the new supply pipe and the new return pipe.

In addition, since the recovered fluid is recovered in a state including air bubbles, there is a problem in that noise increases.

At this time, between the integrated heat exchanger and the inverter pump, there is a reserve hot water storage tank in which the reserve hot water is stored so that the supply pipe and the return pipe are connected so that good quality hot water without temperature deviation can be immediately supplied during the peak time of hot water supply for each floor household.

On the other hand, the diameters of the supply pipe and the return pipe are gradually narrowed toward the higher floors, and it is preferable to maintain the same diameter in each floor generation.

At this time, the household for each floor is provided with a household heat exchanger connected to a supply pipe and a return pipe that circulates the hot water heat exchanged through the circulation pump installed therein to the distributor, and is branched from the supply pipe and the hot water of the supply pipe is directly supplied. It is preferable to be provided.

It is preferably configured to include;

At this time, it is preferable that the exhaust hole is formed to have a gradually smaller diameter toward the outside of the chamber, and the exhaust hole is closed by a flexible damper.

Finally, it is preferable that a turning rib is provided on the inner circumferential surface of the drain hole in the longitudinal direction of the drain hole so that the drained return water is drained along the inner circumferential surface of the drain hole to reduce the flow rate.

1 is a view showing an apartment house integrated piping control system according to the present invention, FIG. 2 is an enlarged view showing the household by floor of FIG. It is a cross-sectional view of the device.

As shown in FIGS. 1 to 3, the apartment house integrated piping control system 200 of the present invention supplies hot water heat-exchanged through the integrated heat exchanger 90 of the machine room to households by floor, and heat-exchanged through the households for each floor. a supply pipe 11 and a return pipe 13 for returning the return water to the integrated heat exchanger 90; an inverter pump 20 installed in parallel on the return pipe 13 and operated according to the temperature of the hot water and return water and the differential pressure between the supply pipe 11 and the return pipe 13; a main controller 30 sensing the temperature of the hot water and return water, sensing the differential pressure between the supply pipe 11 and the return pipe 13, and controlling the schedule of the inverter pump 20 based on the sensed value; The uppermost layer of the supply pipe 11 and the return pipe 13 is installed in the bypass pipe 43 connecting the supply pipe 11 and the return pipe 13, and the differential pressure between the supply pipe 11 and the return pipe 13 is a differential pressure flow control valve 40 for bypassing a portion of the hot water in the supply pipe 11 to the return pipe 13 by opening the valve when it occurs; and a bubble removal device 100 that is installed in plurality on the conduit of the water return pipe 13 and removes and drains air bubbles contained in the return water.

Prior to the description, the integrated piping control system 200 is configured such that preliminary hot water having a set temperature is always on standby in the preliminary hot water storage tank 50 so that hot water can be immediately supplied when hot water is used, and the rotation speed of the inverter pump 20 is adjusted. It controls according to the temperature and differential pressure of hot water and return water, and the biggest feature is that the noise in the pipe is removed by removing bubbles in the return water.

The supply pipe 11 and the return pipe 13 allow the hot water heat-exchanged through the integrated heat exchanger 90 of the machine room to be supplied to each floor of the apartment house, and the return water whose temperature has dropped due to heat exchange through each floor is integrated heat exchange. It returns to the group (90).

As shown in Fig. 1, the supply pipe 11 and the return pipe 13 are installed to extend along the height of the apartment house, and are branched so that the supply of hot water and the recovery of the return water can be made to the households on each floor. .

At this time, the diameters of the supply pipe 11 and the return pipe 13 are gradually narrowed toward the higher floors in the drawing, and it is preferable to maintain the same diameter in each floor household, which is the supply pipe 11 and the return water supply pipe 11 of each floor household. This is to fundamentally prevent the pressure difference between the pressure of the hot water supplied to each floor and the returned water from occurring by preventing the water pressure from dropping as it goes upward by maintaining the same diameter of the pipe 13 .

On the other hand, the integrated heat exchanger (90) is provided with a pipe so that the medium hot water of about 100 degrees supplied from the combined heat and power plant or the medium temperature water boiler can be circulated, and the returned water is returned through the integrated heat exchanger (90) at a set temperature. It is heat-exchanged with hot water and supplied to the supply pipe 11 through a preliminary hot water storage tank 50 to be described later.

At this time, a temperature control valve 91 for controlling the supply amount of medium hot water is installed on the pipe for supplying the medium hot water to the integrated heat exchanger 90 , and the temperature control valve 91 is the main controller 30 to be described later. The opening degree is controlled according to the control. For example, in the case of a cold season, since the temperature difference between the supplied hot water and the returned water is large, by increasing the opening amount of the temperature control valve 91 through the control of the main controller 30 to speed up the flow of medium hot water, By supplying the heat-exchanged hot water at a higher temperature than the set temperature, it prevents the temperature of the return water from dropping relatively seriously, and keeps the indoor temperature of each floor constant.

On the other hand, a spare hot water storage tank 50 is provided between the integrated heat exchanger 90 and the inverter pump 20 to be described later as shown in FIG. Reserved hot water is stored.

The supply pipe 11 and the return pipe 13 are connected to one side of the preliminary hot water storage tank 50 , and the hot water exchanged with the integrated heat exchanger 90 can be supplied to the preliminary hot water storage tank 50 at the other side. A convection pipe (15) passing through the integrated heat exchanger (90) is installed.

In addition, the convection pipe 15 is provided with a convection circulation pump 17 that is controlled by a local controller 33 to be described later so that the heat-exchanged hot water can flow quickly or at a low speed in accordance with environmental factors.

In addition, the supply pipe 11 is coupled to the upper layer of the preliminary hot water storage tank 50 so that the hot water heat exchanged through the integrated heat exchanger 90 can be immediately supplied, and the return pipe 13 is the reserved hot water because the return water is returned. It is preferable to be coupled to the lower layer of the storage tank (50).

In addition, it is preferable that a water supply pipe 60 for supplying tap water to the inside of the preliminary hot water storage tank 50 as much as the amount of hot water used is connected to the lower side of the drawing of the preliminary hot water storage tank 50, which is used in each floor. This is to prevent disruption to the hot water supply by allowing tap water to be replenished as much as the amount of hot water.

The preliminary hot water storage tank 50 as above continuously stores the hot water heat-exchanged through the integrated heat exchanger 90 , and discharges the hot water through the supply pipe 11 , and the return water flowing through the return pipe 13 . It is discharged to the integrated heat exchanger 90 together with the supplemented tap water to circulate the hot water.

In addition, since the hot water of the set temperature is always stored in the reserve hot water storage tank 50, when the use of hot water increases after a stagnant period (late night) when there is no hot water flow in the supply pipe 11 and the return pipe 13 Ensure that stored hot water is immediately supplied.

That is, when the hot water consumption of each floor increases rapidly during the hot water supply peak time (6-8 am, 6-8 pm) after midnight, the hot water pre-stored in the preliminary hot water storage tank 50 is first transferred to the hot water supply destination (85). By supplying it, the return water and tap water flowing into the preliminary hot water storage tank 50 in the meantime flow into the preliminary hot water storage tank 50 through the integrated heat exchanger 90, so that the hot water of good quality that can be supplied immediately is stored ( stand by), and high-quality hot water without temperature deviation can be used.

If there is no reserve hot water storage tank 50 at the peak time as described above, the amount of hot water supplied rapidly increases as the number of hot water supply destinations 85 increases at the same time. This is relatively small, so there is a problem in that the temperature of the hot water is supplied irregularly.

Therefore, the reserve hot water storage tank 50 can efficiently respond to a sudden cold day or an increase in instantaneous hot water consumption.

In addition, there is no need for a separate heat exchanger for hot water supply as in the prior art.

The inverter pump 20 operates according to the temperature of the hot water supplied through the supply pipe 11 and the return water recovered through the household by floor through the return pipe 13 and the differential pressure between the supply pipe 11 and the return pipe 13 . this is done

To this end, the inverter pump 20 is composed of two and is installed in parallel on the pipe of the return pipe 13 .

The inverter pump 20 is controlled by the main controller 30 .

The main controller 30 senses the temperature of the hot water and return water in the supply pipe 11 and the return pipe 13, and senses the differential pressure between the supply pipe 11 and the return pipe 13, and based on the sensed value, the inverter pump The rotation of the inverter pump 20 is controlled according to the schedule of (20), that is, a preset menu.

To this end, the supply pipe 11 and the return pipe 13 have a temperature sensor ( 71) and a pressure sensor 73 are installed, respectively.

The temperature sensor 71 and the pressure sensor 73 may be connected to the main controller 30 by wire or wirelessly, and the inverter pump 20 may also be connected to the main controller 30 by wire or wirelessly.

In general, when there is no hot water supply in each floor household during the late night time period, the inverter pump 20 continuously rotates the minimum mandatory rotation even though the flow of hot water and return water in the supply pipe 11 and the return pipe 13 is extremely small. (Operation close to idling) causes an overload of the inverter pump 20, which eventually causes the inverter pump 20 to be lost or broken.

In order to prevent the above accident in advance, in the main controller 30, the pressure difference in the supply pipe 11 and the return pipe 13 and the temperature difference between the flowing hot water and the return water are measured by the pressure sensor 73 and the temperature sensor. It is sensed through (71), and the rotation speed of the inverter pump 20 is controlled based on the detected value.

In particular, in late-night hours when hot water is rarely used, the pressure difference is sensed through the pressure sensor 73 to prevent an excessive pressure difference between the supply pipe 11 and the return pipe 13 from occurring, and the inverter adapts to the pressure difference. By lowering the rotation speed of the pump 20, the energy consumption is reduced.

In addition, the conventional inverter pump 20 senses only the temperature of the return water, drives it when the temperature is low, raises the temperature of the return water, and stops when the temperature of the return water is restored to normal.

However, the temperature of the return water is sensed by sensing because the return water flows in a state with a drop in temperature as it goes through the households by floor. There is a problem that makes it difficult. This is because, in a state in which the flow of the return water is stagnant, the temperature is slightly lowered, so the exact temperature of the return water is not sensed.

That is, in the main controller 30, since it is difficult to detect the temperature of the return water when the return water is stagnant, the temperature sensor 71 and the pressure sensor 73 respectively installed in the supply pipe 11 and the return pipe 13 are used. Through this, the temperature and pressure of the return water are sensed in real time, and the rotation speed of the inverter pump 20 is controlled based on the detected value.

More precisely, since the rotation of the inverter pump 20 does not need to be fast when the return water is stagnant, the rotation speed of the inverter pump 20 is controlled slowly, and when the flow of return water occurs, the inverter pump adapts to the temperature change of the return water. (20) to control the rotation speed.

For example, when the temperature of the supplied hot water is 55 degrees and the temperature of the return water to be returned is set to 40 degrees, in the case of a cold season (usually 13 degrees or less), the recovered temperature drops to 40 degrees or less and a large temperature deviation occurs. is recovered In this case, the temperature of the supplied hot water is raised to 55 degrees or higher so that the temperature of the recovered water can be recovered to 40 degrees C.

To this end, the main controller 30 controls the opening degree of the temperature control valve 91 of the pipe to which the medium hot water is supplied from the cogeneration plant through the local controller 33, which will be described later, so that the return water is heat-exchanged to 55 degrees or more through the heat exchanger. do.

On the other hand, it is preferable that the main controller 30 is exposed to the outside and an outdoor temperature sensor 75 for detecting the outside air temperature is connected, and the outside air temperature sensor 75 is installed in a commonly called white leaf.

The outdoor temperature sensor 75 detects the instantaneous instantaneous sudden change in the temperature of the outdoor air and transmits it to the main controller 30, thereby controlling the temperature control valve 91 so that the temperature of the hot water can be increased in response to the changing temperature. do.

In addition, the local controller 33 may be connected to the main controller 30 by wire or wirelessly.

The local controller 33 receives a command from the main controller 30 to control the opening degree of the temperature control valve 91 installed in the pipe of the front end (supply side) of the integrated heat exchanger 90 and the convection circulation pump of the convection pipe 15 at the same time. (17) is controlled.

That is, the local controller 33 controls the temperature control valve 91 and the convection circulation pump 17 in real time, and the temperature control valve ( 91) is increased to increase the inflow of medium hot water, and at the same time, the convection circulation pump 17 is operated so that heat exchange through the convection pipe 15 is quickly achieved.

In this case, the heat-exchanged hot water flows into the preliminary hot water storage tank 50 and is immediately supplied to each floor through the supply pipe 11 .

The differential pressure flow control valve 40 is installed on the pipe line of the bypass pipe 43 connecting the supply pipe 11 and the return pipe 13 to the uppermost layer of the supply pipe 11 and the return pipe 13, as shown in FIG. , serves to bypass a portion of the hot water in the supply pipe 11 to the return pipe 13 by opening a valve when a differential pressure is generated between the supply pipe 11 and the return pipe 13 .

That is, the differential pressure flow control valve 40 takes a lot of pressure in the supply pipe 11 by the continuous driving of the inverter pump 20 when there is no use of hot water during the late-night hours of the interseasonal season, and on the contrary, in the return pipe 13 By sensing the pressure when the pressure difference between the supply pipe 11 and the return pipe 13 is excessively generated due to the suction caused by the drive of the inverter pump 20, the opening degree of the differential pressure flow control valve 40 is It is mechanically operated so that the pressure difference between the supply pipe 11 and the return pipe 13 can be adjusted.

In addition, the differential pressure flow control valve 40 does not operate in the winter season, because the supply of hot water for heating is continuously made in all households, so that the circulation of hot water and return water is continuously made to the supply pipe 11 and This is because a large differential pressure in the return pipe 13 does not occur.

However, when only some of the households for each floor use hot water, the circulation speed of hot water and return water is different. In this case, the main controller 30 senses the pressure and temperature of the hot water and return water based on the sensed values. The rotation speed of the inverter pump 20 is controlled according to the circulation speed of hot water and return water.

Therefore, the differential pressure flow control valve 40 induces the flow of hot water by opening the differential pressure flow control valve 40 when there is no use of hot water in the seasons, for example, in the supply pipe 11 and the pressure in the return pipe 13 . and to circulate the hot water in the reserve hot water storage tank 50 while maintaining the set temperature.

In addition, as the opening degree of the differential pressure flow control valve 40 is mechanically manipulated, there is no need for a connection through a wire line with the central monitoring panel (machine room) as in the prior art, thereby reducing construction cost and convenient maintenance.

On the other hand, in each floor household, as shown in FIG. 2 , a household heat exchanger 80 connected to a supply pipe 11 and a return pipe 13 for circulating the hot water heat-exchanged through the circulation pump 81 installed therein to the distributor 82 is provided. and a hot water supply destination 85 branched from the supply pipe 11 to receive hot water directly from the supply pipe 11 is provided, and the same is applied to the households on each floor.

The hot water source 85 is a place where the hot water supplied from the supply pipe 11 is directly supplied without going through the household heat exchanger 80 , and there are kitchens and toilets.

The household heat exchanger (80) is provided with an automatic valve (84) for controlling the amount of hot water supplied from the supply pipe (11).

The circulation pump 81 is connected to the distributor 82 of the household by floor so that the hot water heat exchanged in the household heat exchanger 80 is supplied to the heating coil 83 of each room to be heated, and to the heating coil 83 The amount of supplied hot water is controlled by the control of the distributor 82 .

The automatic valve 84 and the circulation pump 81 are connected to the unit controller 87, the unit controller 87 is connected to the room temperature controller 86, and the unit controller 87 is connected to the automatic valve 84. ) and the circulation pump 81 so that each room is heated according to the set temperature.

Reference numeral 19, which has not been described, is an expansion tank installed in the return pipe 13 and for maintaining a constant pressure in the pipe. Among the symbols, M is a flow meter, and F is a constant flow variable.

The bubble removal device 100 introduces the return water recovered through the household for each floor into the return water pipe 13, removes air bubbles contained in the return water, and drains it back to the return water pipe 13, the return water pipe 13 It is installed in plurality on the pipeline of

That is, the bubble removal device 100 may be installed between each household by floor as shown in FIG. 1 , and may be installed singly at the lower side of the water exchange pipe 13 in each building.

The bubble removal device 100 includes a chamber 110 , a flow path guide 120 , and a drain hole 130 as shown in FIG. 3 .

The chamber 110 may have a cylindrical, polygonal or square shape having a predetermined length, and is installed on the conduit of the return pipe 13 through the coupler (C).

Inside the chamber 110, a fresh water space 111 is formed in which the return water flowing into the inside through the water return pipe 13 is stored, and the upper part of the chamber 110 in the drawing contains the return water flowing into the inside. A plurality of exhaust holes 112 for exhausting gas to the outside of the chamber 110 are formed to pass through.

At this time, each exhaust hole 112 is formed to gradually decrease in diameter toward the outside of the chamber 110 so that gas is exhausted from the inside of the chamber 110 to the outside as shown in the enlarged view of FIG. 3 , and at the same time. , to block the penetration of outside air into the chamber 110 due to the pressure difference between the inside and the outside.

In addition, the plurality of exhaust holes 112 are closed by the flexible damper 113, and the flexible damper 113 is preferably made of soft rubber or silicon having bending and elasticity. This allows the gas included in the return water to be exhausted through the exhaust hole 112 when the return water flows into the chamber 110, and when the return water is full in the chamber 110, the flexible damper 113 is shown in FIG. This is to block the return water from leaking to the outside by closing the inlets of the exhaust holes 112 as shown by the virtual line of

The flow guide 120 is installed to be inclined at a predetermined angle inside the chamber 110 to bisect the incoming return water to remove gas, and to guide the divided return water to flow down toward the inner wall of the chamber 110 .

That is, the flow guide 120 divides the incoming return water in both directions as shown in FIG. 3 , so that the gas included in the return water is quickly exhausted, and at the same time, the return water falling by the inclined flow guide 120 . By allowing it to flow along the inner wall of the chamber 110 while minimizing the impact of

Alternatively, even if bubbles are generated while the return water is being freshened in the fresh water space 111 , the bubbles rise to the fresh water space 111 and are exhausted to the outside through the exhaust hole 112 .

The drain port 130 re-drains the return water stored in the fresh water space 111 of the chamber 110 in a state in which the gas is removed to the return pipe 13 , and is disposed under the flow path guide 120 . It is connected through the return pipe (13) and the coupler (C).

In this case, the drain port 130 maintains the shape of the upper and lower gorges, which are gradually narrowed toward the lower part in the longitudinal direction so that the drained return water can be gradually collected in the lower direction.

In addition, as shown in FIG. 3 , the return water drained from the inner circumferential surface of the drain port 130 is drained along the inner circumferential surface of the drain hole 130 so that the flow rate of the return water can be reduced. A pivot rib 131 having a predetermined width toward the center of the drain hole 130 is provided.

That is, the return water overflowing through the upper perimeter of the drain port 130 flows along the swivel rib 131 with a gentle slope, so the flow rate is slowed, and the flow rate is gradually collected as it goes downward in a slowed state. By allowing it to be drained, the return water to be drained does not contain air, thereby fundamentally blocking the generation of air bubbles.

Therefore, when the return water fresh water in the fresh water space 111 overflows around the upper end of the drain hole 130 and is drained, the drain port 130 collects the return water in the vertical direction, which lowers the flow rate of the return water, and then into the return water pipe 13 . By re-draining, bubbles are prevented from being formed in the drained Linton water.

As described so far, the integrated piping control system of the apartment house of the present invention allows the reserve hot water maintaining the set temperature to be stored in the reserve hot water storage tank, so that a large amount of hot water is supplied at the same time during peak times after late night hours in winter or extreme cold. When this is done, there is an excellent effect of abundantly supplying high-quality hot water with no temperature deviation without waiting time.

In addition, by controlling the drive speed of the inverter pump according to the temperature, pressure, and flow rate of the return water, the power consumption of the inverter pump is reduced and the temperature of the return water is prevented from dropping dramatically in the case of severe cold, so that the indoor The technical effect of preventing a sudden drop in temperature is also excellent.

In particular, there is an effect of saving energy by controlling the rotational speed of the inverter pump by sensing the pressure difference between the supply pipe and the return pipe when the heating load of each floor is different in seasons other than the cold season.

In addition, by removing the bubbles contained in the return water, there is an effect of fundamentally blocking the noise of the water return pipe according to the recovery of the return water.

In the above, the apartment house integrated piping control system of the present invention has been described with reference to the preferred embodiment and the accompanying drawings, but this is only intended to help the understanding of the present invention and is not intended to limit the technical scope of the present invention.

That is, without departing from the technical gist of the present invention, various modifications or modifications are possible by those skilled in the art to which the present invention pertains, and such changes or modifications are within the technical scope of the present invention in the interpretation of the claims. It goes without saying that it is within.
