Description

Heating device and its method {Heating Apparatus and Heating method}

The present invention relates to a heating device and a heating method, and more particularly, to a heating device and a heating method for effectively heating by periodically supplying and blocking heating water supplied to individual heating zones.

The general heating device is configured to heat the heating water by passing the heat of the heating water into each of the heating zones while passing through the heating water inlet pipe branched from the inlet pipe and connected to each heating zone.

Such a heating device opens or blocks an opening / closing valve for opening and closing a flow of heating water to the heating zone to supply heating water to a heating zone to be heated.

In heating by using a conventional heating device, the user attempts to reduce the heating cost by opening the on-off valve of the heating zone to be heated and closing the on / off valve of the heating zone that does not require heating.

However, especially in the case of district heating, the central plant receives continuous heating water. Therefore, even if the heating valves in some heating zones are closed, the heating cost is higher than that of the heating valves in the entire heating zone. have. The reason for this is that when the shutoff valves of some heating zones are closed, the flow rate of the heating water flowing to the heating water supply pipe is faster than the open shutoff valves of the entire heating zone. This is because heating water is discharged without being delivered to the zone.

In other words, when the on-off valves of all heating zones are opened, the water-moisture engines in each of the heating zones act as a resistance to prevent the flow rate from increasing, but when the on-off valves of some heating zones are opened, This reduces the resistance role by the flow rate is faster.

First, a heating method according to an embodiment of the present invention will be described in detail with reference to FIG. 1.

The heating method according to the present invention includes a plurality of heating water supply pipes (10, 20, 30, 40, 50) branched from the inlet pipe (100) into which the heating water is introduced, and the heating water supply pipes (10, 20, 30, A method of heating a plurality of heating zones (1, 2, 3, 4, 5) corresponding to 40 and 50, respectively.

First, a user is provided in the heating moisture engines (10, 20, 30, 40, 50), a plurality of opening and closing the flow of the heating water flowing in the heating moisture engines (10, 20, 30, 40, 50) The heating zones 1, 2, 3, 4 and 5 to be heated are selected by opening or closing the open / close valves 11, 21, 31, 41 and 51 (S10).

The user opens and closes the open / close valves 11, 21, 31, 41, and 51 of the heating zones 1, 2, 3, 4, and 5 to be heated, and the heating zones 1, 2, 3, 4, For 5), the closing valves 11, 21, 31, 41, and 51 are closed to select the heating zones 1, 2, 3, 4, and 5 to be heated.

Subsequently, the user sets a desired heating temperature by using the temperature controllers 12, 22, 32, 42, and 52 provided in the heating zones 1, 2, 3, 4, and 5 (S20).

The thermostat 12, 22, 32, 42, 52 senses the room temperature of the heating zone (1, 2, 3, 4, 5) and calculates the temperature difference between the set temperature, the thermostat 12, 22, In accordance with the temperature difference calculated by 32, 42, and 52, a supply cycle DELTA ST of the heating water supplied to the heating moisture engines 10, 20, 30, 40, and 50 is set (S30). Specifically, the supply period ΔST is a time until the open / close valves 11, 21, 31, 41, and 51 are opened and then reopened, and the valve controller 60 opens and closes every supply cycle ΔST. The valves 11, 21, 31, 41 and 51 are controlled to open.

In this case, the supply period ΔST is set to be shorter as the temperature difference is larger, which is to supply heating water in a shorter period to the heating zones 1, 2, 3, 4, and 5 where the temperature difference is relatively large.

Subsequently, the valve controller 60 identifies the number of the opening / closing valves 11, 21, 31, 41, and 51 in the open state, and accordingly, the valve controller 60 is provided to the heating water supply pipe 10, 20, 30, 40, 50. A time for continuously supplying heating water, that is, a supply duration time ΔRT is set (S40). Specifically, the supply duration time (ΔRT) is the on-off valve (11, 21, 31, 41, 51) is opened from the time the heating water flows open and close the valve 11, 21, 31, 41, 51 is closed The valve controller 60 controls the opening and closing of the on-off valves 11, 21, 31, 41, and 51 by the time until the flow of water is interrupted.

When the supply period ΔST and the supply duration ΔRT are set, the heating zones 1, 2, 3, 4, and 5 are opened via the open / close valves 11, 21, 31, 41, and 51. Heating water is supplied. The heating water flows into the heating water supply pipes 10, 20, 30, 40, and 50 during the supply duration ΔRT for each supply cycle ΔST (S50).

Specifically, the valve controller 60 opens the on / off valves 11, 21, 31, 41, and 51 of the selected heating zones 1, 2, 3, 4, and 5 for each supply cycle ΔST to provide heating water. In this case, the valve controller 60 closes the on / off valves 11, 21, 31, 41, and 51 when the supply duration ΔRT elapses, and the heating water flows only during the supply duration ΔRT. To do that.

In this way, the heating water stays in the heating water supply pipe (10, 20, 30, 40, 50) until the heating water is re-supplied in the next supply cycle (△ ST) after the supply duration time (△ RT) has elapsed. Heat is effectively transferred to the heating zones 1, 2, 3, 4, 5.

While heating continues while repeating the supply cycle ΔST and the supply duration ΔRT, when there are heating zones 1, 2, 3, 4, 5 reaching the set temperature (S60) The controller 60 opens / closes the valves 11, 21, 31, of the heating water supply pipes 10, 20, 30, 40, and 50 corresponding to the heating zones 1, 2, 3, 4, and 5 that have reached the set temperatures. 41, 51 are closed (S70), the supply duration time (ΔRT) is reset according to the number of the opening and closing valves (11, 21, 31, 41, 51) to maintain the open state, opening and closing to maintain the open state For the heating zones 1, 2, 3, 4, 5 corresponding to the valves 11, 21, 31, 41, 51, between the room temperature and the set temperature of the heating zones 1, 2, 3, 4, 5 The supply period DELTA ST is reset by recalculating the temperature difference of.

At this time, the supply duration ΔRT is set to be shorter as the number of open / close valves 11, 21, 31, 41, and 51 decreases. When the number of open / close valves 11, 21, 31, 41, and 51 decreases, the flow velocity of the heating water supply pipes 10, 20, 30, 40, and 50 is relatively increased, so that the heat of the heating water is sufficiently heated. Since the heating water is discharged to the discharge pipe 200 in a state where it is not delivered to (1, 2, 3, 4, 5), the supply duration time (ΔRT) is reduced in proportion to the flow rate being increased, and the supply duration time (△ Closing the on / off valves 11, 21, 31, 41 and 51 after the elapse of RT reduces the flow rate of unnecessary discharged water and relatively maintains the heating water in the heating water supply pipes 10, 20, 30, 40 and 50. The longer the time is, the heat of the heating water is effectively transmitted to the heating zone (1, 2, 3, 4, 5).

Subsequently, heating is continued in the same manner as described above based on the reset supply cycle ΔST and the supply duration time ΔRT, and all the heating zones 1, 2, 3, 4, 5 are allowed to reach the set temperature. Repeat until (S80, S90).

Hereinafter, a heating apparatus implementing the method will be described in detail.

It is configured to be discharged to the 200, the heating zones (1, 2, 3, 4, 5) corresponding to each heating moisture pipe (10, 20, 30, 40, 50) to absorb the heat of the heating water to be heated It is composed.

2 to 4, the heating apparatus of the embodiment of the present invention, the opening and closing valves (11, 21, 31, 41, 51), the temperature controller (12, 22, 32, 42, 52), the valve controller 60 It is configured to include).

The open / close valves 11, 21, 31, 41, and 51 are provided in the heating water supply pipes 10, 20, 30, 40, and 50, and flow through the heating water supply pipes 10, 20, 30, 40, and 50. Open or close the flow of heating water. In the present embodiment, a plurality of heating and moisture engines 10, 20, 30, 40, and 50 are formed corresponding to each of the heating zones 1, 2, 3, 4, and 5, and the heating and moisture engines 10, 20, Opening and closing valves 11, 21, 31, 41, and 51 are installed at every 30, 40 and 50. The on-off valves 11, 21, 31, 41, and 51 are controlled by a valve controller 60 to be described later.

The thermostats 12, 22, 32, 42, 52 are provided in the heating zones (1, 2, 3, 4, 5), sensing the room temperature of the heating zones (1, 2, 3, 4, 5) And to set the desired heating temperature. In the present embodiment, the temperature controller 12, 22, 32, 42, 52 is installed for each heating zone (1, 2, 3, 4, 5).

The temperature difference between the room temperature of each heating zone (1, 2, 3, 4, 5) and the set temperature set by the user is calculated by the temperature controller (12, 22, 32, 42, 52), and according to the temperature difference The supply cycle ΔST of the heating water supplied to the heating moisture engines 10, 20, 30, 40, and 50 is set. The supply period ΔST is set shorter as the temperature difference is larger.

The valve controller 60 identifies whether the on / off valves 11, 21, 31, 41, 51 are opened or closed, and opens or closes the on / off valves 11, 21, 31, 41, 51. The heating water is supplied to the heating water supply pipes 10, 20, 30, 40, and 50 according to the number of the open / close valves 11, 21, 31, 41, and 51 in the open state identified by the valve controller 60. The flow time, that is, the supply duration time DELTA RT, is set. The supply duration ΔRT is set longer as the number of open / close valves 11, 21, 31, 41, and 51 in the open state increases.

The valve controller 60 opens the on / off valves 11, 21, 31, 41, and 51 during the supply duration ΔRT for each supply cycle ΔST, and the heating water after the supply duration ΔRT has elapsed. Close the shutoff valves 11, 21, 31, 41 and 51 until resupply.

Hereinafter, the operation of the heating apparatus according to the above configuration will be described through specific examples.

As shown in FIG. 2, in the heating apparatus according to the present embodiment, five heating water supply pipes 10, 20, 30, 40, and 50 are provided between the inflow pipe 100 and the discharge pipe 200 of the heating water. Five heating zones 1 to 5 are provided to correspond to the heating moisture engines 10, 20, 30, 40, and 50, and open / close valves 11 are provided for each heating moisture engine 10, 20, 30, 40, and 50. , 21, 31, 41, 51 are provided, and each of the heating zones (1, 2, 3, 4, 5) is provided with a temperature controller (12, 22, 32, 42, 52).

The user sets the supply period ΔST of the heating water according to the temperature difference between the room temperature and the set temperature of the heating zones 1, 2, 3, 4, 5, for example, as shown in Table 1 below. The supply period ΔST is set such that the supply period ΔST is shortened as the temperature difference increases, and may be changed as necessary.

And, according to the number of open and close valves in the open state, the supply duration time (ΔRT) of the heating water is set, for example, as shown in [Table 2] below, and the supply duration time (ΔRT) is the open / close valve 11. The larger the number of, 21, 31, 41, and 51 is set, the longer it becomes. The supply duration ΔRT can also be changed as necessary.

[Table 2]

3 shows the open / close valves 11, 21, 31, and 41 of the heating zones 1 to 4 of the five open / close valves 11, 21, 31, 41, and 51, and the open / close valves of the heating zone 5 51 shows the operation of the heating apparatus according to the present invention when in the closed state.

The temperature difference between the room temperature and the set temperature of the heating zones 1 to 4 in which the open / close valves 11, 21, 31, and 41 are opened is ΔT1 = 1 ° C, ΔT2 = 2 ° C, ΔT3 = 3 ° C, and ΔT4, respectively. Since = 4 ° C, the supply cycle? ST of each heating zone in the above Table 1 is set to? ST1 = 2,? ST2 = 1.5,? ST3 = 1 and? ST4 = 0.5, respectively. (Where ΔTn is the temperature difference of the heating zone n and ΔSTn is the supply cycle of the heating zone n, n = 1,2,3,4)

Since the number? N of the on / off valves 11, 21, 31, and 41 in the open state is four, the supply duration time? RT in the above Table 2 is set to? RT = 10.

Accordingly, the valve controller 60 opens and closes the valves 11, 21, 31, and 41 for each supply period ΔST corresponding to the heating zones 1, 2, 3, and 4, and the supply cycle Δ The opening / closing valves 11, 21, 31, and 41 are kept open for each ST of the supply duration ΔRT, and when the supply duration ΔRT has elapsed, until the next supply cycle ΔST. Close the on / off valves (11, 21, 31, 41).

Specifically, the supply duration ΔRT of the heating water is set to 10 minutes, and the supply cycle ΔST of each of the heating zones 1, 2, 3, and 4 is for 2 hours for the heating zone 1, and the heating zone 2 1 hour 30 minutes, heating zone 3 is set to 1 hour, heating zone 4 is set to 30 minutes.

Accordingly, when the heating is started, the heating water flows to the heating water supply pipe 10 of the heating zone 1 for 10 minutes, and the opening / closing valve 11 is kept closed for 1 hour and 50 minutes thereafter. . That is, in the heating zone 1, the time for which the heating water flows (10 minutes) and the time that does not flow (1 hour 50 minutes) is repeated every 2 hours.

Like the heating zone 1, the heating zone 2 has heating water for 10 minutes of the supply duration time ΔRT every 1 hour 30 minutes of the supply cycle ΔST and no heating water for the remaining 1 hour 20 minutes. The heating zone 3 is supplied with heating water for 10 minutes and the heating water is not flowed for 50 minutes, and the heating zone 4 is supplied every 30 minutes with supply cycle (△ ST) for every 1 hour of the supply cycle (△ ST). The heating water flows for 10 minutes and no heating water flows for 20 minutes.

In this way, each of the heating zones 1, 2, 3, and 4 is a time for the heating water to flow in the heating water supply pipes 10, 20, 30, 40 and the time of staying in the heating water supply pipes 10, 20, 30, 40. This is repeated periodically and heated.

Next, the operation when there is a heating zone where the set temperature is reached while heating is continued will be described.

The valve controller 60 closes the on / off valve of the heating water supply pipe when the heating zone reaches the set temperature, and resets the supply duration time ΔRT according to the number of the on / off valves to maintain the open state. The supply period ΔST is reset by recalculating the temperature difference between the room temperature of the heating zone and the set temperature of the heating zone corresponding to the open / close valve maintaining the open state.

FIG. 4 shows the operation when the room temperature of the heating zone 1 reaches the set temperature while heating is performed according to FIG.

When the room temperature of the heating zone 1 reaches the set temperature, the valve controller 60 closes the open / close valve 11 of the heating zone 1 so that the heating water is no longer supplied to the heating zone 1.

The temperature controllers 22, 32, and 42 are heated zones when the on / off valves 11 of the heating zone 1 are closed at room temperature of the heating zones 2 to 4 in which the shutoff valves 21, 31, and 41 are open. The temperature difference between the room temperature of 2 to 4 and the set temperature is recalculated.

As a result, each of the temperature differences between the heating zones 2 to 4 was sensed as ΔT 2 = 1 ° C., ΔT 3 = 2 ° C., and ΔT 4 = 3 ° C. Since the heating is performed for a predetermined time until the closing valve 11 of the heating zone 1 is closed, the temperature difference between the heating zones 2 to 4 is reduced.

According to the temperature difference between the heating zones 2 to 4, the supply period ΔST of the heating zones 2 to 4 is reset by the above [Table 1]. That is, ΔST2 = 2 of the heating zone 2, ΔST3 = 1.5 of the heating zone 3, and ΔST4 = 1 of the heating zone 4 are reset.

In addition, the open / close valves 21, 31, and 41 maintaining the open state are reduced from four to three, and the supply duration time ΔRT is reset from 10 to 8 minutes by the above [Table 2]. .

In this way, the supply period ΔST and the supply duration time ΔRT are reset, and the heating of the heating zones 2 to 4 is performed as described in FIG.

Specifically, in the heating zone 2, the heating water flows for 8 minutes every 2 hours and the remaining 1 hour 52 minutes the heating water stays in the heating water supply pipe 20, and the heating zone 3 is heating for 8 minutes every 1 hour 30 minutes. Water flows and the remaining one hour and twenty-two minutes the heating water stays in the heating water supply engine 30, the heating zone 4 is the heating water flows for eight minutes every one hour and the remaining 52 minutes to allow the heating water to stay in the heating water supply engine (40) do.

As such, the heating zones 2 to 4 are heated while the heating water flows in the heating water supply pipes 20, 30 and 40 and the time of staying in the heating water supply pipes 20, 30 and 40 periodically and is heated. When any one of 4 to 4 reaches the set temperature, the process of heating by resetting the supply period ΔST and the supply duration time ΔRT again is repeated.

As described above, the heating apparatus according to the present invention enables the heating zone to be efficiently heated by shortening the supply cycle of the heating water as the heating zone has a large temperature difference.

In addition, since the supply duration of the heating water is adjusted according to the number of the opening and closing valves in the open state, the number of the opening and closing valves is changed so that the heating can be efficiently performed even if the flow rate of the heating water flowing in the heating water supply pipe is changed.

In other words, if the number of open / close valves decreases, the flow rate of the heating water flowing to the heating water supply pipe becomes faster through the opening / closing valve. Therefore, the supply duration is shortened, so that Reduces the flow rate and closes the on / off valve after the supply duration has elapsed, so that the heating water stays in the heating water supply pipe until the heating water is supplied again in the next supply cycle, so that the heat of the heating water is sufficiently heated during the stay.
