ローテーション制御を行ない、各温水ボイラの運転時間
が年間を通してほぼ均一化されるようにしていた。(b) Background technology In recent years, instead of installing large-capacity hot water boilers in apartment complexes, company housing, and other housing complexes, hospitals, and inns, multiple small-capacity hot water boilers have been installed, and the number of boilers required is adjusted according to the hot water supply load. The conventional system for controlling the number of hot water boilers in operation covers the hot water supply load and prevents unnecessary hot water storage by operating only one hot water boiler. In order to prevent the operating time from becoming too long, rotation control was carried out in which the selection order of the hot water boilers was changed by one -'f)f as appropriate, so that the operating time of each hot water boiler was approximately equalized throughout the year.

点があった。However, the selection switch for increasing or decreasing the number of operating hot water boilers in response to the hot water supply load has a specific operation order1, and the operation of the hot water boiler is determined based on the operation state of the selection switch based on this operation order. Since the conditions are determined, if the operation order is not followed, for example, when reducing the number of units in operation, there is the inconvenience of having to stop the hot water boiler that was previously in operation and start operating another hot water boiler. occurs. Furthermore, the circuit connection between the selection switch and the rotation mechanism is complicated, resulting in an expensive device.

。(B) Main Points of the Invention In the present invention, a stepwise voltage is generated according to the number of operated switches by a setting circuit equipped with the same number of switches as a plurality of control devices operated by program commands and/or manually. Then, a level discrimination circuit that discriminates the level of the output voltage of the setting circuit generates a comparison output with a weight corresponding to the number of operated switches. The operation control device determines the number of operating control devices according to the weight of the comparison output of the level discrimination circuit, and shifts the selection order of the control devices one by one in synchronization with fluctuations in the weight of the comparison output.
((Operate the required number of control devices according to the load.

順序と無関係であるので、設定回路との間での回路結線
が不要になり、全体の回路構成が簡単になる。In the device of the present invention having such a configuration, even if the switch operations in the setting circuit are performed randomly, the number of switch operations is converted into a weighted comparison output by the level discrimination circuit, so that the number of switch operations is The operation control device can increase or decrease the number of operating control devices in an orderly manner without determining the order. In addition, as the weight of the comparison output of the level discrimination circuit changes (for example, the weight decreases as the number of switch operations decreases), the selection order of the control devices shifts by one, and the operation of each 1ttlj control device changes. The time can be equalized. However, since the operation control device depends only on the comparison output of the level discrimination circuit and is unrelated to the order of operation of the switches in the setting circuit, there is no need for circuit connection with the setting circuit, and the overall circuit configuration is becomes easier.

or PS3) is used with a 24-hour program set in advance according to the hot water supply load, the manual switches (MSI) or MS3) are all connected to the center contact as shown in the diagram and connected in series with the program timer switch. . The number of timer switch operations (turning on) increases or decreases depending on the fluctuations in the hot water supply load during the day. For example, just before the peak demand time such as in the evening, the number of operation switches becomes 3, and when there is almost no hot water supply load such as late at night. When there is no one, the number of operations becomes O. In this way, the timer switch is turned on in accordance with the hot water supply load, and the setting circuit (3) generates a stepwise output voltage as shown in Table 1, depending on the number of times the setting circuit (3) is operated. The output voltage of the setting circuit (3) is amplified by the amplifying circuit (4), then level determined by the level determining circuit (5), and weighted according to the number of timer switch operations as shown in Table 2. is converted into a comparison output.

Therefore, if we are currently in mode ■, the AND elements of the AND circuit (ADZ) and (AD3) cannot output, and the AND element of the AND circuit (ADI) is in the level discrimination circuit (5).

In mode l[, AND circuit (AT) 3) is selected, and depending on the weight of the comparison output, drive relay (5) → drive relay (
C) → drive relay (B) is selectively energized in this order. That is,
When the comparison output is [0, 0, 0], all drive relays are not energized, when it is [0, 0, 1], the drive relay is energized first, and when it is [0, 1, 1], the drive relay is not energized. The driving relay (C) is energized together with the relay prisoner, and when [1, 1, 1], the driving relays (5), (Q and (I3)) are all energized.Then, in the state of mode III, the number of operated relays is reduced. If there is a decrease in the weight of the comparison output, the mode returns to mode I.The above operations are summarized as shown in Table 4.

イラの次の選択順位の温水ボイラとなる。As is clear from Table 4, when the weight of the comparison output increases as the number of operations increases, the drive relays are sequentially turned on according to a predetermined selection order within the same mode. vice versa,
When the number of operated items decreases and the weight of the comparison output decreases, the mode changes as follows: Engineering→■, ■→■, III→I, so the selection order of the drive relays shifts one by one and the energization of the drive relays changes. The number is decreasing. Due to this increase/decrease in the number of operations,
The hot water boiler whose operation will be stopped is the hot water boiler corresponding to the first drive relay that is energized among those currently in operation, and the operation will be started from the hot water boiler that is next in selection order after the hot water boiler that entered last. It becomes a hot water boiler.

It is also possible to do so. In the latter case, if each manual switch is connected to the right contact, the number of hot water boilers can be increased even if the program timer switch is open, and conversely, if each manual switch is connected to the left contact, the program timer switch can be operated. The number of hot water boilers in operation can be reduced even if water boilers are used.

Even if the switch operation order is not specified and is performed at random, the number of hot water boilers in operation can be increased or decreased by the operation control device (6).
It is done in an orderly manner and there is no need to worry about any inconvenience. Moreover, each time the weight of the comparison output of the level discrimination circuit (5) decreases, the selection order of the hot water boilers is shifted, and the operating time of each hot water boiler can be equalized. Moreover, since the operation control device (6) determines the number of hot water boilers to be operated and the selection order based on the weight and weight fluctuation of the level discrimination circuit (5), it is necessary to connect the circuit directly to the setting circuit (3). () The overall circuit configuration can be simplified.

In this case, even if the switch operation order is random, the control equipment can be started and stopped in a regular manner according to load fluctuations. The number of times the control device starts and stops can be reduced without causing the inconvenience of operating other control devices. In addition, since the operation control device fig: controls the number of control devices and rotation control according to the weight of the comparison output of the level discrimination circuit and the fluctuation of the weight, it is possible to directly connect the setting circuit and the operation control device. The operation time of each control device can be equalized while simplifying the overall circuit configuration. Furthermore, since the switch operations can be performed in a random order, it is extremely easy to operate the switches by program command or manually, and there is no need to worry about erroneous operation.
