Description

  The present invention relates to a floor heating system using hot water, and more particularly to a method for controlling a hot water floor heating system using ubiquitous information.

  As one of the heating methods, there is a hot water type floor heating system in which warm water is circulated under the floor to heat the floor surface. In general, warm water type floor heating warms indoor air from the hot water through the floor or the heat storage material and the floor, so it is necessary to first warm the floor or the heat storage material and the floor during heating. It takes time to obtain (temperature rise). Therefore, in order to improve the comfort by obtaining the heating state at the required temperature when necessary, the heating device operation (pre-operation) is performed slightly before the floor heating is actually required (about 10 minutes to several hours). ) Must be started. In particular, the heat storage type floor heating requires time to store heat in the heat storage material in advance before the time of starting heating (pre-heating operation). However, the time for this preliminary operation (pre-operation, pre-heating operation) varies not only from the structure of the floor heating system and the structure of the building where the floor heating is installed, but also from the weather conditions such as the outside air temperature. In other words, the pre-heating time required for heat storage before the pre-operation time and the heating start time varies depending on each device and according to the weather conditions, and the user himself / herself determines the pre-operation start time and operation time. I had to operate (reserved operation, stop, etc.).

  Patent Document 1 discloses a hot water type floor heating system using solar heat, but nothing is said about the pre-operation. Patent Document 2 discloses a hot water type floor heating system that uses both solar heat and an auxiliary boiler. Heating operation using only solar heat is performed about two weeks to one month before the time when heating is to be started. The setting is described. Patent Document 3 discloses a heat storage type floor heating system including a mortar layer for heat storage and a heating element, but nothing is described about the pre-operation. Furthermore, Patent Document 4 discloses a heat storage type floor heating system including a heat storage material and a heating element, but nothing is described about the pre-operation.

  As described above, since warm water type floor heating takes time to rise in temperature, it is desirable to start operation (pre-operation) slightly before the heating start time (about ten minutes to several hours). In addition, in the regenerative hot water type floor heating, it takes time to prestore heat in the heat storage material (pre-heating operation). However, the time for this pre-operation (pre-operation, pre-heating operation) changes not only from the structure of the floor heating system but also from the weather conditions such as the outside temperature, the structure of the building where the floor heating is installed, etc. For each installed system, the user had to determine the start time and operation time by himself, and it was difficult to perform sufficient heating without waste and at the required time. For this reason, there are many cases where a comfortable temperature condition cannot be obtained when heating is desired. Patent Document 2 describes that a heating operation only using solar heat is set about two weeks to one month before the time when heating is to be started. The idea of the pre-operation is not disclosed.

  In the first means, in addition to the network information as an input to the calculation means, at least one of the usage status and optimum temperature of the section in which the floor heating apparatus is installed is used, and the floor heating apparatus of the section is used. The driving situation may be determined.

The operation of the solar water heating and heating system shown in the figure is roughly divided into the following three modes, and the mode to be operated is selected and executed by the control panel 4. Manual mode selection and operation control are also possible using a manual switch attached to the control panel.
a. Thermal storage mode (thermal storage by solar collector)
b. Heating mode (heating by the stored heat, heating by solar collector)
c. Hot water supply mode (hot water supply)
The hot water supply mode is performed simultaneously with the pre-operation mode and the heating mode or independently.

  An outline of each operation will be described.

(Heat storage by solar heat collector)
In the heat storage by the solar heat collector, the hot water heated by the solar heat collector 11 is circulated to the heat storage heat exchanger 36 built in the hot water storage tank 12, and the hot water heated by the solar heat collector 11 and the hot water storage tank are circulated. The hot water storage of the hot water storage tank 12 is heated by exchanging heat of the 12 hot water storages. At this time, both the electric four-way valves 13 and 14 are operated to the hot water storage / heating position, and the pump 16 is operated. By the operation of the pump 16, the water in the heat storage heat exchanger 36 is sucked and pressurized by the pump 16 through the pipe 27, the electric four-way valve 14, and the pipe 25, and sent to the solar heat collector 11 through the pipe 20. The water heated by the solar heat collected by the solar heat collector 11 returns to the heat storage heat exchanger 36 in the hot water tank 12 through the pipe 19, the electric four-way valve 13 and the pipe 29, and the hot water in the hot water tank 12 is stored. The temperature of the hot water stored in the hot water storage tank 12 is increased by heat exchange. This circulation is repeated and the temperature of the hot water storage tank 12 is raised.

The control panel 4 operates in this mode when the temperature of the solar heat collector 11 exceeds a preset temperature, and stops when the temperature drops below that temperature.
(Heating by the stored heat)
This operation is an operation for heating the hot water tank 12 by circulating the hot water in the hot water coil 23. At this time, both the electric four-way valves 13 and 14 are operated to the hot water storage / heating position, and the pump 15 is operated. The hot water heated by heat exchange with the hot water in the hot water storage tank 12 by the heating heat exchanger 37 is sucked and pressurized by the operation of the pump 15, and enters the inlet header 18 through the pipe 28, the electric four-way valve 13 and the pipe 21. Is sent to. The hot water fed into the inlet header 18 is introduced into a hot water coil 23 divided into a plurality of systems from here, and heats while dissipating heat while passing through the hot water coil 23. The hot water that has been divided into a plurality of systems and passed through the hot water coil 23 joins at the outlet header 17, returns to the heating heat exchanger 37 in the hot water tank 12 through the pipe 24, the electric four-way valve 14, and the pipe 26, and The temperature is raised by exchanging heat with the hot water inside. Heating is performed by repeating this circulation.

The control panel 4 selects this operation when the amount of heat in the hot water storage tank 12 is insufficient, but the amount of heat collected by the solar heat collector 11 is sufficient.
(Hot water supply)
This operation is an operation of supplying hot water regardless of the heat storage or heating. The hot water introduced into the hot water storage tank 12 from the hot water supply pipe 31 is heat-exchanged with the heat storage heat exchanger 36 in the hot water storage tank 12 and heated, and then sent to the hot water supply pipe 34 through the pipe 33 and the hot water supply boiler 30. In the hot water supply boiler 30, when the inflowing hot water is lower than a predetermined temperature, it is automatically ignited, heated, and heated.

  In the heating mode, it is selected by the control panel 4 whether to operate the heating by the stored heat or the heating by the solar heat collector, and the control panel 4 also sets the start and stop of the operation in the selected operation. Controlled. Of course, it is also possible to manually select the operation and manually start and stop the operation in the selected operation. However, the hot water supply mode is always executable when the apparatus power is turned on.

The control panel 4 performs the following control in relation to selection of the operation mode and start / stop of the operation.
(Determination of heating start time and pre-heating operation)
The calculation means (microcomputer) built in the control panel 4 reads the network information 7 stored in the server 3 periodically. The computing means includes recent weather data and past weather data (average time-series change data of average temperature) included in the network information 7, recent thermal environment data of each room in the house where the solar water heating and heating system is installed, and past Based on the thermal environment data (time series change data of average room temperature), equipment information (floor heating method), etc., a heating start date and a heating stop date are determined to determine when to start the pre-heating operation. In other words, the computing means compares the read recent weather data with the past weather data (time series change data of the average temperature), and the recent thermal environment data and past thermal environment data (average time series of the average room temperature) of each room in the house. Change data), the number of days after which the average temperature and the average room temperature become the reference temperature (reference temperature for starting heating) stored in the storage means, that is, the heating start date is estimated.

  In order to start heating on the heating start day, it is necessary to perform a pre-heating operation in which the temperature of the hot water stored in the hot water storage tank 12 is raised to a predetermined temperature set in advance. The calculation means refers to the current weather data, the temperature of the hot water storage tank 12, and the past preheating operation data stored in the storage means, and sets the start date and start time of the preheating operation. And when the start date and the start time come, the pre-heating operation (heat storage) is started in the (heat storage by solar heat collector) mode.

When the temperature of the hot water storage tank 12 rises to the predetermined temperature, the preheating operation is stopped, and the data of the preheating operation is stored in the storage means. If the pre-heating operation is not completed by the heating start date, data of the pre-heating operation from the start of the pre-heating operation to the heating start date is stored in the storage unit.
(Heating operation)
When the pre-heating operation is completed, the calculation unit sets the operation mode to the heating mode, and based on the network information 7 read from the server 3 and the information on the electric four-way valves 13 and 14 and the pumps 15 and 16, the solar hot water supply Various conditions (operation start time, operation state of each room (heating intensity), etc.) for the heating system operation are determined, and operation control is performed thereby.

  The determination procedure in the present embodiment will be described with reference to FIGS. First, the calculation means sets the operation mode to the heating mode in the procedure 1 of FIG. The computing means reads the network information 7 at a predetermined time interval, and monitors whether the daily minimum temperature (either forecast or measured value) is below 20 ° C. (procedure 2).

  If the temperature is not lower than 20 ° C., the procedure 2 is repeated again at a predetermined time interval. When the daily minimum temperature falls below 20 ° C., the process proceeds to step 3 and the presence / absence of an occupant is confirmed based on the network information 7. If it is confirmed that there is a person in the room, the procedure proceeds to step 4 to set the heating intensity. In the present embodiment, the heating intensity is set in five levels from level 1 (weak) to 5 (strong), and which one is set is determined by the difference between the heating target temperature and the room temperature at the start of heating. For example, if the heating target temperature is 24 ° C., the temperature is set to level 5 when the room temperature is 5 ° C. lower than that, and is set to level 3 otherwise. After the start of operation, proportional control based on the difference between the heating target temperature (room temperature or floor surface temperature or a combination of both) and the actual temperature is continuously performed based on the set level. Changes may be made. The warm water circulation amount to the hot water coil 23 is determined by the above levels 1 to 5, and the warm water circulation amount to the hot water coil 23 is set by the number of rotations of the pump 15 or the pump 16 and the electric valve opening degree of the inlet header outlet. When the heating intensity is set, the process proceeds to step 5 and the heating operation (heating by the stored heat) at the set heating intensity is started immediately.

  When it is confirmed in step 3 that no occupant is present, the resident return time pattern included in the network information 7 is first referred to by the calculation means, and the return time is estimated. Then, the heating operation time is determined based on the estimated return time (procedure 6).

If heating operation time is determined, it will progress to procedure 7 and pre-operation time will be set up. Data on the outside air temperature and room temperature in the network information 7 is referred to, and a pre-operation time set in advance according to the outside air temperature (daily minimum temperature) or room temperature is set. For example, if the daily minimum temperature T _L is 10 ° C <T _L ≤ 20 ° C, 0.5 hour, 0 ° <T _L ≤ 10 ° C, 1.0 hour, T _L ≤ 0 ° C, 1.5 hour, You may make it adjust the said time based on the room temperature and external temperature of a division. If the room temperature and the outside air temperature of the heating target section are higher than the predetermined temperatures, the pre-operation time is shortened. The pre-operation start time is a time that is back by the pre-9 operation time from the heating operation time.

  Next, the procedure proceeds to step 8, and the heating intensity is set following the procedure 4. When the heating intensity is set, it is confirmed whether or not the pre-operation start time has come at predetermined time intervals until the pre-operation start time is reached (procedure 9). If the pre-operation start time is not reached, the procedure returns to step 3. The above procedure is repeated. When the pre-operation start time is reached, the procedure proceeds to step 10 and the pre-operation is started. In the pre-operation, the actual operation is an operation of heating by the stored heat.

  Next, with reference to FIG. 4, the control procedure after the heating operation is started in procedure 5 will be described. When the operation is started, the presence / absence of an occupant is confirmed based on the network information 7 at predetermined time intervals (procedure 11). When the presence of a room occupant is confirmed in step 11, the heating intensity is changed by a predetermined level in accordance with the number of occupants (procedure 15). For example, if there are three occupants, the heating intensity level is lowered by one step, and if there are five occupants, the heating intensity level is lowered by two steps. Procedures 11 to 15 are repeated at predetermined time intervals.

  If there is no occupant in step 11, the heating intensity is reduced to level 1 (procedure 12), and the procedure returns to step 11 at a predetermined time interval to confirm the presence or absence of the occupant. If the state of no occupants continues even after one hour, the heating operation is stopped (procedures 13 and 14), and the process returns to procedure 2 in FIG.

  Next, with reference to FIG. 5, the control procedure after starting the pre-operation in the procedure 10 will be described. When the pre-operation is started, the presence / absence of an occupant is confirmed based on the network information 7 at predetermined time intervals (procedure 16).

  If there is no occupant, the process proceeds to step 17, and it is determined whether or not the estimated time to return is estimated in step 6 of FIG. If it is not the expected time to go home, the pre-run is continued as it is (procedure 18), and the process returns to step 16 after a predetermined time. If it is the expected return home time, the process proceeds to step 19, the heating intensity is changed to level 1 and the heating operation is continued, and it is determined whether or not 1 hour has elapsed from the expected return home time after a predetermined time (procedure 20). . If one hour has not elapsed since the estimated return home time, the procedure returns to step 16. If one hour has elapsed since the estimated return home procedure, the operation is stopped and the procedure returns to step 2, that is, the initial driving state in FIG. .

  In the case where there are occupants in the procedure 16, the number of occupants is confirmed based on the network information 7, and, as in the procedure 15, the heating is performed only at a level determined in advance according to the number of occupants. The intensity is changed (procedure 22). After changing the heating intensity, the process proceeds to step 23, where presence / absence of the occupant is confirmed at predetermined time intervals. If there is an occupant, the procedure returns to step 22 to adjust the heating intensity. If the procedures 22 to 23 are repeated at predetermined time intervals and no occupant is present in the procedure 23, the procedure proceeds to the procedure 24, and the heating intensity is changed to the level 1 (procedure 24). After changing to level 1, it is confirmed at a predetermined time interval whether or not 1 hour has passed since it was confirmed that there is no occupant (procedure 25), and if 1 hour has not passed, the process returns to procedure 23. If it is confirmed in step 25 that one hour has passed since it was confirmed that there is no occupant, the procedure proceeds to step 26 at that point to stop the operation and return to step 2 in FIG.

  In the present embodiment, as described above, based on the ubiquitous information, that is, the network information 7, the start time of the pre-heating operation, the start time of the pre-operation, and the heating intensity during the heating operation are automatically changed. Since the hot water heater is operated at an appropriate heating intensity when necessary, the comfort of heating is improved.

In the above embodiment, the calculation means is provided in the control panel 4, but both the calculation means and the storage means may be provided in the server 3.

The data of the pre-heating operation includes the time required for heat storage in the heat storage concrete. Since other configurations are the same as those of the first embodiment, illustration and description thereof are omitted.
