Description

The present invention relates to a hot water supply system, and more particularly to a hot water supply system that clears a learning use pattern that is unlikely to reflect actual hot water supply use.

Conventionally, a heat pump heat source machine in which a compressor, a condensing heat exchanger, an expansion means, and an evaporation heat exchanger are connected by a refrigerant circuit, a hot water storage tank for storing hot water heated by this heat pump heat source machine, and a hot water storage tank. A hot water storage device and a hot water supply system equipped with a circulation pump that circulates hot water between the hot water storage tank and the heat pump heat source machine and an auxiliary heat source machine for reheating when the hot water temperature of the hot water storage tank drops are widely used. It is offered to.

Then, in this type of hot water storage device or hot water supply system (hereinafter referred to as hot water supply system), usually, every time the data of the hot water supply usage pattern is learned for a certain period (for example, one week), the learning use which is the future predicted hot water storage pattern is used. A learning storage means for updating and storing a pattern is provided, and the hot water supply system is operated based on the above learning usage pattern.

By the way, when a new hot water supply system is installed and operation is started, there is no record of hot water supply use and the learning usage pattern is incomplete. Therefore, a preset standard usage pattern is used for a certain period including the trial run period. The hot water supply system is operated based on the above. Then, data on the hot water supply usage pattern will be accumulated even during the test run period.

In the immediate hot water supply type hot water supply device of Patent Document 1, in the learning mode, when the operation start time and stop time of the heat retaining control means are learned and stored based on the hot water supply time and the setting of the operation start time is changed. It is disclosed that the setting is changed after the power is cut off.

Japanese Patent No. 2592529

Like the hot water supply system, the hot water supply system is operated based on a preset standard usage pattern for a certain period including the trial run period after the start of operation of the hot water supply system. During that time, data on hot water usage patterns will be accumulated. However, since the hot water supply usage pattern during the trial run period is different from the actual hot water supply usage pattern by the user, when creating a learning usage pattern using the hot water supply usage data during the trial run period, the actual hot water supply usage by the user The learning usage pattern is different from the pattern, and the learning usage pattern lacks practicality.

In addition, even when the user is shifting to actual use, the user may be absent for a long period of time (for example, one or several weeks) due to travel, etc., but in that case, the season may change during the absence. There is also a high possibility that the learning usage pattern will not reflect the actual hot water usage pattern because the learning usage pattern is not updated during the absence.

In addition, at the transition from winter to spring, from summer to autumn, etc., there is a high possibility that people will move or move due to transfer or enrollment, and the pattern of hot water supply usage will change as the users of the hot water supply system change. Because of the possibility, it may be desirable to clear the learning usage pattern that was previously used.

An object of the present invention is to provide a hot water supply system that clears a learning use pattern that is unlikely to reflect actual hot water supply use.

The hot water supply system according to claim 1 is a hot water supply system provided with a heating device for heating water and a hot water storage tank for storing hot water, and updates and stores a learning usage pattern every time data on hot water usage is learned for a certain period of time. The learning storage means is provided and is configured to operate the hot water supply system based on the learning use pattern, and when the power supply is reset before the lapse of the certain period from the start of use of the hot water supply system, the learning storage means. The feature is that the learning information stored in is cleared.
The "reset" of the power supply means that the power supply is turned off and then turned on.

According to the above configuration, when the power supply is reset before a certain period of time has elapsed from the start of use of the hot water supply system due to the end of the trial run after the start of use of the hot water supply system, the learning information stored in the learning storage means is stored. Since it is cleared, the learning usage pattern is not created based on the data of hot water supply usage during the trial run. Therefore, the learning usage pattern created after that can reflect the actual hot water supply usage.

In the invention of claim 1, the hot water supply system of claim 2 clears the learning use pattern stored in the learning storage means when the power is turned on after a predetermined period or more has passed after the power was turned off. It is characterized by being done.

According to the above configuration, when the user is absent for a predetermined period (for example, one week) or more due to a user's trip or the like, the power is turned on after a predetermined period or more has passed after the power was turned off. In such a case, the season may change during the absence, and the learning usage pattern is not updated during that time, so there is a high possibility that the learning usage pattern will not reflect the actual hot water supply usage pattern.

Therefore, in such a case, the learning usage pattern stored in the learning storage means is cleared, and a new learning usage pattern is created based on the subsequent hot water supply usage pattern.
Even if the owner of the building changes, the memorized learning usage pattern is cleared in the same manner as above.

In the invention of claim 1 or 2, the hot water supply system according to claim 3 resets the power supply when the hot water supply system is operated based on the learning use pattern after a certain period of time has elapsed from the start of use of the hot water supply system. When the seasonal determination is different before and after, the learning use pattern stored in the learning storage means is cleared.

According to the above configuration, there is a high possibility that people will move or move at the turn of the season, and the users of the hot water supply system will likely change. Therefore, when the seasonal determination is different before and after the power supply is reset, the learning usage pattern stored in the learning storage means is cleared, and a new learning usage pattern is created based on the subsequent hot water supply usage pattern.

The hot water supply system of claim 4 is based on the invention of claim 3, wherein the seasonal determination is based on the outside air temperature or the clean water temperature detected by the outside air temperature detecting means or the clean water temperature detecting means equipped in the hot water supply system. It is characterized by being carried out.
According to the above configuration, since the hot water supply system is usually provided with an outside air temperature thermistor and a tap water temperature thermistor, it is possible to make effective use of these to perform seasonal determination based on the outside air temperature or the clean water temperature. can.

The hot water supply system according to claim 5 operates the hot water supply system based on a preset standard use pattern for a certain period after the learning use pattern is cleared in the invention of any one of claims 2 to 4. It is characterized by being configured to do.
When the learning usage pattern is cleared, the next learning usage pattern will be created based on the hot water supply usage pattern during the next fixed period, but during that fixed period, a preset standard usage pattern will be created. Since the hot water supply system is operated based on the above, the operation of the hot water supply system is not hindered.

As described above, the present invention has various effects.

The heat pump heat source machine 3 includes a heat pump circuit in which a compressor 37, a condensing heat exchanger 38, an expansion valve 39, and an evaporation heat exchanger 40 are connected by a refrigerant pipe 41. In this heat pump heat source machine 3, the refrigerant sealed in the refrigerant pipe 41 is compressed by the compressor 37 to raise the temperature, and the circulation pump 19 is driven to heat the hot water flowing through the circulation heating circuit 15 to a high temperature in the condensation heat exchanger 38. It is heated by heat exchange with the refrigerant of. The refrigerant after heat exchange expands with the expansion valve 39 to become lower than the outside air, absorbs heat from the outside air with the evaporation heat exchanger 40, and then is introduced into the compressor 37 again.

The heat of vaporization exchanger 40 includes an outside air temperature sensor 40a for detecting the outside air temperature and a blower 40b. The heat pump heat source machine 3 includes an auxiliary control unit 42 that controls a compressor 37, an expansion valve 39, a blower 40b, and the like. The auxiliary control unit 42 is communicably connected to the control unit 43 and controls the heat pump heat source machine 3 according to a command from the control unit 43. The outside air temperature detected by the outside air temperature sensor 40a is transmitted to the control unit 43 via the auxiliary control unit 42.

Next, various controls adopted in the hot water supply system 1 will be described.
In this hot water supply system 1, the actual hot water supply usage patterns for a certain period (for example, one week) are stored, and based on the data of the hot water supply usage patterns for those fixed periods, the predicted hot water storage that should be stored in the hot water storage tank 4 is predicted. The learning usage pattern for one day corresponding to the amount of heat is repeatedly set, and the learning usage pattern is updated and memorized.
The control unit 43 is backed up by a secondary battery having a predetermined capacity even when the power is off.

As shown in FIG. 2, the hot water supply usage pattern shows a hot water supply usage pattern for 24 hours obtained from the average value of hot water supply usage data for a certain period based on the hot water supply usage amount detected by the flow rate sensor 11b. be.
The learning use pattern shown in FIG. 2 shows a hot water storage pattern in which the amount of heat corresponding to the amount of hot water used is stored up to 1 hour before the use of hot water every 60 minutes in order to enable hot water supply like the pattern of hot water supply. Is. The hot water storage pattern (learning use pattern) is calculated via calorific value calculation using the detection data of the temperature sensors 24a, 7a, 8a, 11a and the flow meter 11b.

Next, the learning memory control for updating and storing the learning usage pattern every time the hot water usage data is learned for a certain period of time will be described with reference to the flowchart of FIG. The learning memory control program is stored in the control unit 43 (which corresponds to the learning memory means), and the reference numerals Si (i = 1, 2, ...) In the flowchart indicate each step. ..

When this learning memory control is started, various signals are read from sensors (temperature sensors 24a, 7a, 8a, 11a, flow meter 11b, etc.) in S1 and then in S2, the amount of hot water used every 60 minutes. The data is calculated in chronological order.
Next, in S3, the data of the hot water supply usage amount every 60 minutes is stored in a predetermined memory in association with the date, day of the week, and time zone, and then in S4, the hot water supply for one week from Monday to Sunday. It is determined whether or not the data of the usage pattern is stored. If the determination is No, the process returns to S1 and S1 to S3 are repeated. If the determination of S4 is Yes, the process proceeds to S5.

In S5, the hot water supply usage pattern for one day is calculated using the average value of the data of the hot water supply usage pattern for one week from Monday to Sunday, and the hot water supply usage pattern for one day is set for a predetermined time (for example, 1). Through the time) advance process and the calorific value calculation process, the learning usage pattern applied in the next week is calculated, and the previous learning usage pattern stored in the memory is updated.

Next, the hot water supply operation control for operating the hot water supply system 1 will be described with reference to the flowchart of FIG. The hot water supply operation control program is stored in the control unit 43, and this control is executed by the control unit 43.
Here, before explaining this control, based on FIG. 4, one week's worth of hot water supply usage data # 1, # 2, # 3, ..., And learning usage patterns # 1, # 2, # 3 respectively. , ..., and the standard usage pattern will be described.

After the start of use of the hot water supply system 1, hot water supply usage data # 1, # 2, # 3, ... Are sequentially collected every week, and the hot water supply usage data # 1, # 2, # 3, ... Are used. Then, the learning usage patterns # 1, # 2, # 3, ... Are sequentially created and updated, and are applied to the operation of the hot water supply system 1. Since the learning usage pattern is incomplete during the first week, the hot water supply system 1 is operated based on a preset standard usage pattern (default usage pattern) as shown in FIG.

Returning to the flowchart of FIG. 6, it is first determined whether or not the use of the hot water supply system 1 is started in S10. In this determination, the start of use is determined from the predetermined setting information set in the control unit 43, and when the determination in S10 is Yes, the timer T1 is started in S11.

Next, in S12, since the learning use pattern is not completed immediately after the start of operation, the hot water supply system 1 is operated based on a preset standard use pattern.
Next, in S13, it is determined whether or not there is a power reset (power OFF and subsequent power ON), and if the determination is Yes, the process proceeds to S14, and if the determination is No, the process proceeds to S16. In S14, it is determined whether or not a certain period (for example, one week) has elapsed from the start of use of the hot water supply system 1. This determination is made based on the time measured by the timer T1.

When the determination in S14 is Yes, it is highly possible that the power was reset within a certain period from the start of use of the hot water supply system 1 and the power was turned off by the end of the trial run, and then the power was turned on by the user. The learning data (information) that is the hot water supply usage data stored in the memory is cleared. That is, since the data of the hot water supply use in the trial run is different from the hot water supply use by the user, it is not preferable to apply the data of the hot water supply use to the creation of the learning use pattern.

As described above, when the power supply is reset, as shown in the lower part of FIG. 4, the hot water supply usage data before the power supply reset is cleared, and the hot water supply usage data is newly constant after the power supply reset. It will be collected and memorized for each period. Then, the hot water supply system 1 is operated based on the standard usage pattern before a certain period of time elapses from the reset of the power supply.

In S16 following S15, it is determined whether or not there is a learning use pattern, and if the determination is Yes, the hot water supply system 1 is operated based on the learning use pattern in S17.
When the determination in S16 is No, the hot water supply system 1 is operated in S18 based on the standard use pattern. Then, from S17 and S18, it returns to S16 and S16 to S18 are repeated.

Next, with respect to the above-mentioned hot water supply operation control, a learning use pattern clearing process based on a seasonal determination executed by, for example, an interval interrupt every 40 ms will be described with reference to the flowchart of FIG.

After the start of this process, it is determined in S20 whether or not a certain period (for example, one week) has passed from the start of use of the hot water supply system 1. This determination is made based on the timed time of the timer T1. If the determination in S20 is Yes and the above-mentioned fixed period has elapsed and the test run period has elapsed, it is determined in S21 whether or not the power is off, and if the determination is No, the process returns to S21 and repeats S21. .. If the determination of S20 is No, S20 is repeated.

When the determination in S21 is Yes, the season A when the power is turned off in S22 is stored in the memory. At this time, the season A can be determined by acquiring the date information from the clock function of the control unit 43.
In S23 following S22, it is determined whether or not the power is on, and if the determination is No, the process returns to S23 and repeats S23. When the determination in S23 is Yes, the season B when the power is turned on in S24 is stored in the memory. At this time, the season B can be determined by acquiring the date information from the clock function of the control unit 43. The power OFF of S21 and the power ON of S23 correspond to the power reset.

In S25 following S24, it is determined whether or not the above seasons A and B are different, and if the determination is Yes, the learning use pattern is cleared in S26. In the next S27, a command instructing the hot water supply system 1 to be operated based on the standard usage pattern for a certain period of time is issued to the hot water supply operation control, and then returns. If the determination in S25 is No (seasons A and B are the same), S26 and S27 are skipped and returned.

Next, for the above-mentioned hot water supply operation control, a learning use pattern clearing process based on a long-term absence, which is executed by, for example, an interval interrupt every 40 ms, will be described with reference to the flowchart of FIG.

After the start of this process, it is determined in S30 whether or not a certain period (for example, one week) has elapsed from the start of use of the hot water supply system 1. This determination is made based on the timed time of the timer T1. If the determination in S30 is No, S30 is repeated. If the determination in S30 is Yes and the test run period has elapsed after the above-mentioned fixed period has elapsed, it is determined in S31 whether or not the power is turned off. If the determination is No, S31 is repeated and the power is turned off. Then, the timer T2 is started in S32.

Next, in S33, it is determined whether or not the power is on, and if the determination is No, S33 is repeated. It is judged whether or not. This determination is made based on the time measured by the timer T2.

If the determination in S34 is Yes, the learning use pattern is cleared in S35.
That is, if the user is absent for a predetermined period due to travel, etc., the season may have changed during that period, or the user may have changed due to a move or transfer of a building. The usage pattern is cleared.
In S36 following S35, a command instructing the hot water supply system 1 to be operated for a certain period of time based on the standard usage pattern is issued to the hot water supply operation control, and then returns.
If the determination in S34 is No, S35 and S36 are skipped and returned.

Next, the operation and effect of the hot water supply system 1 described above will be described.
If the power supply is reset before a certain period of time has passed since the start of use of the hot water supply system 1, the learning data stored in the memory is cleared, so a learning usage pattern is created based on the hot water supply usage data during the trial run. There is nothing. Therefore, the learning usage pattern created after that can reflect the actual hot water supply usage. The test run includes confirmation of use before actual use.

As described above, when the season determination is different before and after the power supply is reset, the learning usage pattern stored in the memory is cleared.
At the turn of the season, there is a high possibility that people will move or move, and the users of the hot water supply system 1 will likely change. Therefore, the learning use pattern is cleared as described above. In this way, when the learning usage pattern is cleared, a new learning usage pattern is created based on the data of the hot water supply usage for a certain period thereafter.

Here, although not shown in the flowchart, when performing seasonal determination before and after power reset, seasonal determination is performed based on the water supply temperature detected by the water supply temperature sensor 8a (however, the water supply temperature during water supply execution). You can also do it. For example, when the water supply temperature changes by 2 ° C. or more, it is determined that the season has changed. In addition, seasonal determination can be performed based on the outside air temperature detected by the outside air temperature sensor 40a. For example, when the outside air temperature changes by 5 ° C. or more, it is determined that the season has changed. In this way, when the seasonal determination is performed based on the water supply temperature and the outside air temperature, the water supply temperature sensor 8a and the outside air temperature sensor 40a provided in the hot water supply system 1 can be effectively utilized for the determination.

When the user is absent for a predetermined period (for example, one week) or more due to a user's trip or the like, the power is turned on after a predetermined period or more has passed after the power was turned off. In such a case, the season may change during the absence, and the learning usage pattern is not updated during that time, so there is a high possibility that the learning usage pattern will not reflect the actual hot water supply usage pattern. In addition, even if the user changes due to the movement of people or the transfer of a building, there is a high possibility that the learning usage pattern will not reflect the actual hot water supply usage pattern.

Therefore, in such a case, the learning use pattern stored in the memory is cleared, and the hot water supply system 1 is operated according to the standard use pattern. A new learning usage pattern is created based on the subsequent hot water supply usage pattern.

Next, an example of partially modifying the embodiment will be described.
1) The fixed period of S14 in FIG. 6 is not limited to, for example, one week, but may be a period of about one week. Similarly, the fixed period of S20 in FIG. 7 and S30 in FIG. 8 is not limited to, for example, one week, but may be a period of about one week.
Similarly, the predetermined period of S34 in FIG. 8 is not limited to, for example, one week, and may be 10 days or 20 days.

2) The timer T1 in FIG. 6 may be omitted, and instead, the date information obtained from the clock function of the control unit 43 may be stored, and the determination of S14 may be performed using that information. Similarly, the timer T2 in FIG. 8 may be omitted, and instead, the date information obtained from the clock function of the control unit 43 may be stored, and the determination of S34 may be performed using that information.

3) The hot water supply system 1 shows an example, and a fuel cell unit, a gas engine, or the like may be adopted instead of the heat pump heat source machine 3.
4) It is also conceivable to configure the control unit 43 so that the identification information for identifying the user can be registered, and to clear the learning use pattern even when the identification information registered therein is changed.
5) In addition, a person skilled in the art can carry out the embodiment by adding various modifications to the embodiment without departing from the spirit of the present invention, and the present invention also includes such modifications. ..
