Description

How to drive a late-night heat storage device {METHOD FOR OPERATING A ACCUMULATING DEVICE}

The present invention relates to a method of driving a late-night heat storage device, and in particular, is equipped with a plurality of heaters for heating the heat storage device, and detects the temperature at the start of the drive of the heat storage device, and calculates the amount of heat supplied per hour, and then heats to the installed temperature. In order to control the quantity of the heater to be heated and / or the amount of power to be supplied to the drive method of the midnight heat storage type device to have a constant load amount to minimize the amount of load in the driving time of the initial heat storage type device.

In general, late-night regenerative appliances, in particular regenerative boilers, regenerative heaters or regenerative water heaters, are used to minimize the waste of resources by using the power generated in the late night, that is, the amount of electricity used is very small. In other words, the power generated at night is very small compared to the amount generated, so the remaining power is simply discarded in addition to the power consumed.

Therefore, in order to minimize such load and to minimize the load according to the amount of power used during the day, it has been widely used in recent years.

The conventional method for driving a late-night heat storage device is that when each device installed in every place starts to be driven in unison at a time for providing power to the heat storage device, that is, at a time when the night power is provided, the heat is stored at a set temperature. Is driving in the form of stopping.

By this driving method, the amount of use of all electric power is concentrated in the operation time of the initial heat storage type device, and thus a load is generated in power supply. That is, as shown in the graph shown in FIG. 1, the use of all the late night power starts to operate uniformly in accordance with the start time of the late night power, so that the supply of the late night power must be increased due to the load generated initially. Will be generated.

In addition, as the number of users using late-night electricity has recently increased, the use of the late-night electricity is relatively high compared to the supply of the night-time electricity. It is happening.

The present invention is to overcome the above-mentioned conventional problems, an object of the present invention is to install a plurality of heaters for heating the heat storage device and to detect the temperature when starting the drive of the heat storage device to calculate the amount of heat supplied per hour Since the quantity of the heater and / or the amount of power supplied to the heater to be heated to the later installed temperature is controlled, there is provided a method of driving a late-night regenerative regenerative device to have a constant load amount by minimizing the amount of load during the driving time of the initial regenerative device. It is.

In other words, since the required amount of power of the heat storage device is distributed on an average time period, the load concentrated at the beginning of the midnight power supply is distributed to the end point in the middle of the midnight power supply time zone, so that the load of the supply power at some time during the midnight power supply time It is to prevent concentration.

Features of the present invention for achieving the object of the present invention is a standby mode step for starting the drive of the heat storage device; Checking whether a time (setting time) at which midnight power is supplied is reached; Detecting the temperature of the initial heat storage device by a temperature sensor mounted inside the heat storage device when the set time is reached; Calculating a uniform amount of power per hour by averaging the amount of power required for heating the regenerative device and the midnight power supply time period according to the required amount of power (temperature) set by the user by the detected initial temperature of the regenerative device; Controlling the operation of the heater according to the calculated supply amount; Checking whether the heating water of the heat storage device is heated to a temperature set by a user by a temperature sensor over time; Stopping the operation of the heater when the detected temperature of the heating water is equal to or higher than the set temperature; Checking whether the set time (night power supply time) has ended after the operation of the heater is stopped, and if the set time is exceeded, proceeding to the standby mode step; and if the time is not exceeded, proceeding to the set temperature checking step; And checking the set time if the detected temperature in the set temperature checking step is equal to or greater than the set temperature, and if the set time is exceeded, proceeds to the standby mode step through the heater operation stop step, and determines the supply amount per hour if the set time is not exceeded. It is a driving method of a late-night heat storage heat storage device consisting of a setting time check step to proceed to the step.

In the present invention, the setting time checking step is preferably to use a timer to check the late-night power supply time, the heater operation step is the number of heaters that can generate the amount of power required per hour by the switching circuit It is preferable to operate the entire heater mounted by controlling the amount of power required per hour by operating the heat storage device to accumulate the regenerative device or down the voltage supplied by the voltage converter to the required voltage.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

Referring to Fig. 2, there is shown a latent thermal heat storage device driven by the method of the present invention. The configuration of such a heat storage device is not significantly different from the configuration of a conventional heat storage device, and only changes the configuration of the heater 130 used as a heating means, and the configuration of the controller 170 is different.

When the heat storage device is schematically described, it is composed of a heater 130 used as a heating means, a heater 120 heated by the heater 130, and an exterior 110 in which the heating water is accommodated, and the exterior 110. The supply pipe 140 for supplying the heating water and a pipe (not shown) for recovering the circulating heating water are mounted on one side of the), and the pump 150 is mounted on the supply pipe 140.

The heater 130 is electrically connected to the controller 170, and a temperature sensor 160 for measuring a temperature at which the heating water is heated is mounted inside one side of the exterior 110 to be electrically connected to the controller 170. do.

In order to perform the method of the present invention, the heater 130 is composed of a plurality of elements for the basic heating distributed according to the time zone, unlike the configuration installed in the existing heat storage device, in particular, based on the amount of power of 30Kw of 5Kw It is preferable to mount six heaters 130 each having an electric power amount.

Each of the heaters 130 is determined by the number of heaters operated by the controller 170, and only the predetermined heater 130 is operated to distribute the concentration of power.

Referring to the configuration in which the controller 170 and each element is connected through a block diagram shown in FIG. 3, the controller 170 includes a microcomputer 171 and a switching circuit 172. The switching circuit 172 is connected to each heater 130 to control the operation by the signal of the microcomputer 171. In addition, the temperature sensor 160 may be connected to the microcomputer 171 to detect the number of heaters 130 to be operated.

When the driving method of the late-night heat storage heat storage device according to the present invention through this configuration in more detail as follows.

First, the time at which the midnight power is supplied and the time at which the power is cut off is set, and after the user sets a desired heat storage amount (ie, temperature), the controller 170 mounted on the heat storage device is operated. At this time, the process proceeds to the standby mode step S101 for starting the driving of the heat storage device until the supply time of the late night power.

In the setting time checking step (S102), it is checked whether a time when midnight power is supplied by a timer or the like. In this case, the timer used may be used as a component used in a conventional heat storage type heat storage device or may be configured by mounting a separate element.

If it is not the time set by the setting time checking step (S102), the process proceeds to the standby mode step (S101) and maintains the standby state for driving the heat storage device, and if the setting time is reached, the heat storage device appearance 110 In the heat storage device temperature sensing step (S103) by the temperature sensor 160 mounted in the interior of the heat storage device (ie, the temperature of the heating water stored in the heat storage device) is detected.

In the step of determining the amount of supply per hour based on the detected initial temperature of the heat storage device (S104), the amount of power required for heating the heat storage device is equal to the amount of power required for heating the heat storage device according to the required amount of power (temperature), and a uniform amount of power is generated per hour. Will be calculated. In the heater operation step S015, the heater 103 is operated according to the supply amount calculated by the supply amount determination step S104.

In other words, dividing the amount of power required by the user (the amount of power required for temperature rise) by the time when the midnight power is supplied, the amount of power required per hour is calculated, and the heater 130 is operated by the amount of power required per hour. will be.

In this case, the heater 130 may be operated by the number of heaters 130 capable of generating an amount of power required per hour by the switching circuit 172. In another embodiment, a sufficient effect may be obtained even by operating the heater 130 by lowering the voltage supplied by using a voltage converter (not shown) to a required voltage. This is possible because the heater 130 is a heating element using a resistance, because the heater 130 operates as a heating element even if a proper voltage is not supplied.

In the set temperature checking step (S106) by the temperature sensor 160 as time passes, it is checked whether the heating water of the heat storage type device is heated to the temperature set by the user, and when the heater is heated to the set temperature, the heater operation stop step (S107). By the operation of the heater 130 is stopped.

After that, it is checked whether the setting time (night power supply time) has ended by the setting time checking step (S108). If the setting time is exceeded, the process proceeds to the standby mode step (S101) and waits for the next night power supply time. If it is confirmed that less than the set time in the set time check step (S108) to proceed to the set temperature check step (S106) again to check the set temperature.

If the set temperature check step (S106) is confirmed to be less than the set temperature proceeds to the set time check step (S109), if the set time check step (S109) is confirmed to be less than the set time, the power per hour according to the current temperature In order to calculate the supply amount, the process proceeds to the step of determining the supply amount per hour (S104) and the process is repeated.

And when the time set in the setting time checking step (S109) is exceeded, the heater operation stop step (S110) to stop the operation of all heaters 130, go to the standby mode step (S101) the next night power Wait for the supply time.

As such, when the power is used as the average supply amount according to the entire time, the amount of power supplied is uniform as shown in FIG. 5, thereby preventing the load due to the power supply from being concentrated.

The load calculated by the method of driving the heat storage device according to the present invention and the method of driving the heat storage device according to the conventional method is shown in the following table to compare the values. The calculated load was based on 50 households, and the capacity of the heat storage type equipment was 270L, the power amount was 30 Kw * h, and the efficiency of the heater was 100%. The set heat storage was set at 95%, the highest (99% to 90% of heat storage capacity) to 20%, 30% to upper (heat storage capacity of 89% to 70%), and lower (69% of heat storage capacity). To 40%) and 30%, and the lowest (39% to 26% heat storage capacity) was calculated as 20%.

Table 1 shows the load of power consumption according to the conventional method.

As such, in Table 1, power consumption occurs intensively at the time of the initial midnight power supply, which indicates that the initial load is relatively high.

Table 2 shows loads generated by time when the method of controlling the voltage and supplying the average amount of power supplied according to the total usage time according to the embodiment of the present invention.

As shown in Table 2, it can be seen that the concentration of the load is not biased at any given time and low load is generated at a constant rate.

And Table 3 shows the load generated by the time of performing the method of supplying the average amount of power supplied according to the total time of use, which is another embodiment of the method according to the present invention by controlling the number of heaters operated.

As shown in Table 3, the load generated at the beginning of the late-night power supply is slightly larger than the load generated at the end of the power supply, but it can be seen that the overall generated load is generated at a constant rate without being intensively biased at any time.

As described above, the method of driving a late-night heat storage heat storage device according to the present invention detects the temperature at the start of the drive of the heat storage device to calculate the amount of heat supplied per hour, and then the quantity of heaters heated to heat to the installed temperature. And / or controlling the amount of power supplied to prevent the power load from being concentrated at a certain time period, particularly at a time when midnight power is supplied.

In addition, the present invention does not exceed the amount of power supplied by dispersing the power consumption is not concentrated, so the late night power can be efficiently utilized, so no additional power is produced, and the power remaining at night is 90% There is an effect that can be utilized over.
