Correction means for correcting according to the correction data to be performed or according to the monthly correction data stored in advance in the ROM 114 or the like.

The operation will be described.
First, the operation of the hot water supply apparatus will be described.
The number of operating heat source devices 1 is determined according to the operation pattern set by the hot water supply device remote controller 100. For example, if the number of actually installed heat source units 1 is 10 and the set heating capacity of the operation pattern is set to 100 (%), all the 10 heat source units 1 are operated. If the set heating amount is set to 70 (%), seven heat source units 1 are operated, if it is 50 (%), five units, and if 30 (%), three units. Further, the number of operating heat source devices 1 is increased or decreased according to the actual hot water storage amount of the open tank 5 with respect to the set hot water storage amount of the operation pattern. As described above, since a plurality of heat source devices 1 are provided and the number of operating heat source devices 1 can be changed, the overall hot water supply capability can be increased and the hot water supply capability can be adjusted over a wide range.

  When the operation of the heat source unit 1 is started, the operation of the heat pump refrigeration cycle and the operation of the pump 24 are started until the detected temperature Tc of the heat exchanger temperature sensor 31 reaches the set value Tcs based on the conditions shown in FIG. Until the detection temperature Twi of the inflow side temperature sensor 32 reaches the set value Twis, the third flow path of the second three-way valve 26 is closed and the fourth flow path is opened, and the first flow path of the first three-way valve 22 is opened. Is opened and the second flow path is closed. As a result, as shown by arrows in FIG. 2, in the heat pump refrigeration cycle, the refrigerant discharged from the compressor 11 passes through the four-way valve 12, the water heat exchanger 13, the expansion valve 14, the outdoor heat exchanger 15, and the four-way valve 12. Thus, a flow sucked into the compressor 11 is generated, and the water heat exchanger functions as a condenser. In the water cycle, water flows through the pump 24, the water heat exchanger 13, the third pipe 25, the fourth flow path of the second three-way valve 26, the sixth pipe 29, the first pipe 21, and the first flow of the first three-way valve 22. An initial circulation circuit that circulates through the path is formed.

  After the initial circulation circuit is formed, based on the conditions shown in FIG. 4, when the detected temperature Tc of the heat exchanger temperature sensor 31 exceeds the set value Tcs, or the detected temperature Twi of the inflow side temperature sensor 32 becomes the set value Twis. When exceeded, the first flow path of the first three-way valve 22 is opened and the second flow path is closed, and the third flow path of the second three-way valve 26 is opened and the fourth flow path is closed. As a result, as shown by arrows in FIG. 5, the water in the water supply side main pipe 2 passes through the first pipe 21, the first flow path of the first three-way valve 22, the second pipe 23, and the pump 24, and the water heat exchanger. The hot water flowing out from the water heat exchanger 13 passes through the third pipe 25, the third flow path of the second three-way valve 26, the fourth pipe 27, and the fifth pipe 28 to the hot water supply side main pipe 3. A feeding hot water circuit is formed.

  Thus, at the start of operation, an initial circulation circuit is first formed to warm the water heat exchanger 13, and after the water heat exchanger 13 is sufficiently warmed, the hot water is discharged to the hot water supply side main pipe 3, thereby The unnecessary temperature drop of the hot water flowing through the side main pipe 3 can be avoided, and high-temperature water whose temperature has risen sufficiently is supplied to the hot water supply side main pipe 3 and the sealed tank 4.

  In the stopped heat source unit 1, the third flow path of the second three-way valve 26 is closed and the fourth flow path is opened, and the first flow path of the first three-way valve 22 is opened and the second flow path is opened. The hot water supply circuit is closed and the initial circulation circuit of FIG. 2 is prepared. As a result, the hot water in the hot water supply side main pipe 3 made by the operating heat source unit 1 does not flow into the water cycle of the stopped heat source unit 1, and the hot water made by the operating heat source unit 1 and The thermal energy can be supplied and stored in the sealed tank 4 without waste, and energy saving and reliability can be improved.

Next, the operation of the remote controller for hot water supply device 100 will be described.
The main part of each screen display hierarchy in the touch panel type liquid crystal display 101 is shown in FIG. 6, and specific examples of the screen display are shown in FIGS.
First, the “startup menu screen” (FIG. 7) is displayed. The “Startup menu screen” has “Operation monitor button”, “Operation pattern setting button”, “Guide button”, “Operation history button”, “Function setting button”, and “Service button”. A setting screen is selectively displayed.

  The “operation monitor screen” is a screen for displaying the current operation status of the hot water supply device. As shown in FIG. 8, the current hot water storage amount in the open tank 5 and 12 hours before and after the current time are set as the center. The amount of hot water stored is displayed as a bar graph, and the transition of the remaining hot water amount from 12 hours ago to the present is displayed as a line graph. When the “<< (left) button” is touched, the center of the graph display moves one hour ago, and changes in the set hot water storage amount and remaining hot water amount that are older than 12 hours ago are displayed. When the “>> (right) button” is touched, the center of the graph display moves after 1 hour, and the set amount of hot water stored in the future is displayed after 12 hours. Further, the “operation monitor screen” includes “operation button”, “stop button”, and “full power button” for manually operating the hot water supply device. The heat source machine 1 is operated and stopped by touching the “run button” and “stop button”, and the heat source is in a powerful mode with a hot water storage amount 100 (%) and a heating capacity 100 (%) by touching the “full power button”. The machine 1 is operated. Further, the “menu button at start-up” can be returned to by touching the “menu button”.

  The “operation pattern setting screen” is a screen for setting the automatic operation pattern of the hot water supply device. As shown in FIG. 9, “business condition button”, “day / day setting button”, “peak shift setting button”, “ There are “Monthly heating setting button” and “Back button”.

  When the “business type button” is touch-operated, the display is switched to the “business type pattern setting screen” shown in FIG. On the “Pattern setting screen for each business type”, an operation pattern applicable to the facility installed by the user from among a plurality of pre-programmed operation patterns taking into account the type (business type) of the facility where the water heater is installed There are multiple “business type buttons” so that can be selected. Examples of business formats that can be selected and set by the plurality of “business mode-specific buttons” include “hotel / sports gym”, “welfare / hospital”, “lunch / dining room”, “dormitory”, and the like. In addition to the “business type button”, the “business type pattern setting screen” has a “custom button” for setting a custom operation pattern in advance, and a “small button” for setting the amount of daytime heating. ”,“ Ordinary button ”,“ large button ”,“ confirm button ”for setting confirmation, and“ return button ”for returning to the previous screen. Furthermore, on the “business pattern setting screen”, the set heating capacity in units of time for the heat source unit 1 and the set amount of hot water stored in units of time for the open tank 5 are displayed in a bar graph form according to the selected operation pattern. It is easy to understand visually when a person selects a driving pattern. The operation pattern selected and set on this “business condition pattern setting screen” is a basic operation pattern of the hot water supply apparatus thereafter.

  When the “day of the week / day setting button” on the “operation pattern setting screen” is touched, the display is switched to the “day of the week / day setting screen” shown in FIG. On the “day / day setting screen”, a calendar for the current month is displayed and a frame indicating the current day is displayed. Seven “day of the week buttons” for selecting the day of the week in the “day of the week” display part of the calendar, the “day” display part of the entangled “day button” for selecting the day, and the year and month There are two “arrow buttons” for increasing / decreasing and a “return button” for returning to the previous screen. When an arbitrary “day of the week button” is touched, the display is switched to the “day of the week / day pattern setting screen” shown in FIG. On the “Day / Daily pattern setting screen”, “Standard button” to set the standard operation pattern, “+ button” to set the operation pattern with more daytime heating than the standard operation, and less “-Button” to set the operation pattern, “full power button” to set the full power operation to operate the heat source unit 1 in the powerful mode with the hot water storage amount 100 (%) and the heating capacity 100 (%), set holiday "Break button" to perform, "Special 1 button" to "Special 3 button" where the user can freely set the heating amount and target hot water storage amount, "Confirm button" to confirm the selected operation pattern, There is a “return button” to return to the “day / day pattern setting screen”. Furthermore, on the “day of the week / day pattern setting screen”, the set heating capacity of the time unit for the heat source unit 1 and the set hot water storage capacity of the time unit for the open tank 5 are displayed in a bar graph form according to the selected operation pattern. Is done.

  For example, when the “Sunday button” is touched on the “day / day setting screen”, the screen is switched to the “day / day pattern setting screen”. The user selects a desired driving pattern from the eight driving patterns “standard button” to “special 3 button” described above. For example, when the “rest button” is touch-operated, an operation pattern corresponding to “rest” is displayed in a bar graph shape. Touching the “OK” button switches to the “Day of the week / day setting screen”, the “day” corresponding to the Sunday after the current day is changed to a color of “rest pattern” (for example, black display), and non-Saturday is displayed. It can be confirmed that it is set as “Holiday”. Even if any “day button” on the “day / day setting screen” is touched, the above-mentioned “day / day pattern setting screen” is displayed, and the operation pattern for each “day” can be set.

  The operation patterns of the “break button”, “full power button” and “special 1 button” to “special 3 button” that can be selected on the “day / day pattern setting screen” described above are shown in FIG. The user can freely change the setting on the screen. This screen is displayed by touching the “function setting button” on the “startup menu screen” (FIG. 7). It is displayed by touching the “Operation pattern setting button” on the “Function setting screen” (not shown).

  On the “operation pattern change screen”, the operation pattern to be changed can be selected with two “arrow buttons”, and the heating capacity amount and the hot water storage amount can be changed for each time. Furthermore, the set heating capacity in time units for the heat source unit 1 and the set hot water storage amount in time units for the open tank 5 are displayed in a bar graph form. When the time is changed with two “arrow buttons”, a bar graph corresponding to the time is displayed, for example It is displayed in red (shown black). This makes it easy to visually understand the setting change. When the “peak shift setting button” on the “operation pattern setting screen” (FIG. 9) is touched, the display is switched to the “peak shift setting screen” shown in FIG. On the “Peak shift setting screen”, the “Yes button” and “No button” for specifying whether or not the peak value of the heating amount is to be shifted in a predetermined period and time, and the peak value of the heating amount are set to increase or decrease. There are two “arrow buttons” for setting, a “confirmation button” for confirming the setting, and a “return button” for returning to the previous screen.

  When the “monthly boiling setting button” on the “operation pattern setting screen” (FIG. 9) is touched, the display is switched to the “monthly boiling setting screen” shown in FIG. On the “Monthly boiling setting screen”, “Low button” and “High button” for setting the monthly boiling temperature high / low are prepared for each month from January to December, and for setting confirmation "Confirm button" and "Back button" for returning to the previous screen. By the way, each driving pattern is hierarchized on calendar information (year / month / day / hour / minute) as shown in FIG. That is, the operation pattern X2 classified by business type is allocated on the time table X1, and the operation pattern X3 classified by day of the week is allocated on the operation pattern X2 classified by business type. Further, a daily operation pattern X4 is assigned on the day-by-day operation pattern X3, and a manual operation pattern X5 is assigned on the daily operation pattern X4. These operation patterns have execution priorities in the order of X5> X4> X3> X2.

  For example, when the user determines that the current operation of the hot water supply device is not appropriate during operation according to the operation pattern X2 for each business type and changes the operation pattern for a specific day, the subsequent specific day is a day with a higher priority. Operation according to the separate operation pattern X3 is executed. Similarly, when the driving pattern for a specific day is changed, the driving according to the daily driving pattern X4 having a higher priority is executed. Further, when the “run button”, “stop button”, and “full power button” are operated on the “run monitor screen”, the run according to the manual run pattern X5 having a high priority is executed.

  In addition, when the current driving pattern is canceled by the operation of the touch panel type liquid crystal display 101 by the user, the driving pattern set in the past (the driving pattern of the previous day, the driving pattern of the same day of the previous week, the driving of the previous month) Any one of the patterns) may be automatically selected and newly set based on the determination that there is a track record.

  On the other hand, according to the electric power company's fee structure, it is necessary to drive during the nighttime period from 10 am to 8 am the next morning, and during the daytime period from 8 am to 10 am Generally, under the condition that hot water is not used on holidays and hot water is used on weekdays, for example, as shown in FIG. 17, a high hot water storage amount 100 on the day before the holidays (weekdays before holidays). If (%) is set, energy is wasted, and if a low hot water storage amount of 20 (%) is maintained on the day before weekdays (holiday before weekdays), the next day will cause a shortage of hot water. .

  In order to prevent such an inconvenience, among the set driving patterns, the driving patterns for weekdays before holidays and holidays before weekdays are appropriately calibrated according to the days of the week before and after. That is, as shown in FIG. 18, the amount of stored hot water is reduced to, for example, 20 (%) from 10:00 on the day before the holiday (weekdays before the holiday) to avoid unnecessary energy consumption. ) At 10 o'clock in the evening, the amount of stored hot water is increased to, for example, 100 (%), and the lack of hot water the next day is resolved.

  Moreover, the driving | operation pattern used for a driving | operation is correct | amended suitably according to the detection temperature of each outdoor temperature sensor installed in each heat-source equipment 1. FIG. Since the outside air temperature tends to have a thermal influence on the hot water supply operation, such a correction is employed to eliminate the thermal influence.

  As described above, by providing the touch panel type remote controller 100 for a hot water supply device, it is possible to easily set a plurality of operation patterns. In particular, the troublesome work of finely setting the operating conditions over time is unnecessary, and the burden on the user can be greatly reduced. And the effect that the efficient driving pattern according to the difference in a business condition, ie, a user's usage pattern of warm water, can be selected is acquired.

  Moreover, since a wide variety of operation patterns can be incorporated by attaching the external memory 200, it is possible to efficiently and optimally supply hot water in accordance with the hot water usage form, thereby improving versatility and energy saving. To do.

  In the above-described embodiment, the case where there is one open type tank 5 has been described as an example. However, a case where a plurality of open type tanks 5 are provided is also possible. In addition, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention.
