In addition, although the following embodiment demonstrates and applies to the floor heating apparatus as an example of a heating apparatus, it can apply similarly to heating apparatuses of other forms, such as a warm air heating apparatus.

  In FIG. 1, the floor heating apparatus of 1st Embodiment is provided with the floor heating apparatus main body 2 (it comprises a heating apparatus main body), and the control means 4 for operating-controlling this floor heating apparatus main body 2. As shown in FIG. . The floor heating apparatus body 2 is used to warm the indoor space 6 that is a heating target area.

  The floor heating apparatus main body 2 has a floor heating panel 8 installed on the floor, and the floor heating panel 8 is provided with a hot water tube 10 in a meandering manner, for example, and hot water will be described later through the hot water tube 10. Circulated.

  The floor heating device further includes a heat source unit 12 (which constitutes a part of the floor heating device main body 2 in this embodiment) for supplying hot water. The heat source unit 12 includes a combustion burner 14 and a feed pump 16 (see FIG. 3), and hot water is generated using the combustion heat of the combustion burner 14. One end side of the hot water supply line 18 is connected to the supply side of the heat source unit 12, the other end side is connected to the inflow side of the floor heating panel 8, and one end side of the hot water return line 20 is connected to the return side of the heat source unit 12. The other end side is connected to the outflow side of the floor heating panel 8. In addition, a thermal valve 22 is disposed in the hot water supply line 18. With this configuration, when the heat source machine 12 and the thermal valve 22 are operated, the hot water generated by the heat source machine 12 flows into the floor heating panel 8 through the hot water supply line 18 as indicated by an arrow 24. Supplied to the side and flows through the hot water tube 10. Then, the hot water flowing through the hot water tube 10 returns to the heat source machine 12 through the hot water return line 20 as shown by an arrow 26, is heated again by the heat source machine 12, and is supplied through the hot water supply line 18, in this way. Hot water from the heat source machine 12 is circulated through the floor heating panel 8.

  The floor heating apparatus main body 2 is controlled and operated by an operation command from the operation remote controller 30 (which constitutes the operation device), and the operation command from the operation remote controller 30 is sent to the control device 4. Based on the command, the floor heating apparatus body 2 is controlled to operate as will be described later. The operation remote controller 30 may be a wireless type using infrared rays or a wired type using signal lines.

  Referring to FIGS. 2 and 3, the operation remote controller 30 can use, for example, the one shown in FIG. 2, and includes a power switch 32, a heat storage use mode switch 34, a temperature setting switch 36, and a timer setting switch 38. Have. The power switch 32 is for operating and stopping the floor heating device. When the power switch 32 is operated once, the floor heating device is operated, and when operated again, the operation is stopped. The heat storage use mode switch 34 is for setting a heat storage use mode, which will be described later. The heat storage use mode is set when operated once, and the heat storage use mode is canceled when operated again. The temperature setting switch 36 includes an up switch 40 for raising the set temperature and a down switch 42 for lowering the set temperature. By operating the up switch 40 and the down switch 42, a desired set temperature t1 (FIG. 7). The timer switch 38 sets the time until the floor heating device starts and stops operating. In addition, the operation remote controller 30 is provided with a display device 44 (for example, a liquid crystal display device) for displaying command contents when various switches are operated.

  In this floor heating apparatus, a temperature sensor 46 for detecting the temperature of the indoor space 6 (heating target area) is provided, and the temperature sensor 46 is provided in the operation remote controller 30. The temperature sensor 46 may be provided on a side wall or the like that defines the indoor space 6 separately from the operation remote controller 30.

  The control means 4 is composed of, for example, a microprocessor, and the operation control means 50, the operation mode setting means 52, the mode switching means 54, the temperature comparison means 56, the abnormal temperature drop determination means 57, the temperature difference calculation means 58, and the duty ratio setting means. 60. The operation control means 50 is for controlling the operation of the floor heating apparatus main body 2 and controls the operation of the heat source unit 12 (the combustion burner 14 and the feed pump 16) and the thermal valve 22. The operation mode setting means 52 sets the operation mode based on a command from the operation remote controller 30, sets the heat storage use mode when the heat storage use mode switch 34 is operated and selects the heat storage use mode, and the heat storage use mode switch 34. When the heat storage use mode is canceled by operating again, the normal mode is set. The mode switching means 54 forcibly switches from the heat storage use mode to the normal mode as will be described later when the temperature of the indoor space 6 (the temperature detected by the temperature sensor 46) suddenly decreases during the operation of the heat storage use mode. Further, the temperature comparison means 56 compares the temperature of the indoor space 6 with the remaining heat lower limit temperature t2 (see FIG. 7) and the abnormal lower limit temperature t3 (see FIG. 7), as will be described later. When the temperature of the indoor space 6 falls below the abnormal lower limit temperature t3, it is determined that the temperature is in an abnormal temperature drop state. In this embodiment, an abnormal temperature drop signal is generated based on the determination result of the abnormal temperature drop.

  Further, the temperature difference calculating means 58 calculates the temperature difference between the temperature of the indoor space 6 and the set temperature t1 of the operation remote controller 30, and the duty ratio calculating means 60 is based on the temperature difference of the temperature difference calculating means 58. An on (ON) state in which the apparatus main body 2 is activated (in other words, a state in which heating is performed by the floor heating panel 8) and an off (OFF) state in which the floor heating apparatus main body 2 is deactivated (in other words, by the floor heating panel 8). For example, when the temperature difference is 1 ° C., the ratio between the on state and the off state is set to 1: 1. For example, in the normal mode operation control, the operation control is performed with a normal cycle period, and the duty ratio is controlled with each normal cycle period as one cycle. In this embodiment, the time of one cycle is set to 20 minutes, for example. Therefore, when the duty ratio is 1: 1, half of 10 minutes of one cycle time (each normal cycle period) is 20 minutes. The operation is controlled so as to be in the on state and the remaining 10 minutes in the off state.

  The control unit 4 further includes a time measuring unit 62 and a memory unit 64. The time measuring means 62 measures time, and in this embodiment, measures time elapsed since the power switch 32 of the operation remote controller 30 is turned on. Further, the memory means 64 stores a residual heat lower limit temperature t2 that becomes a reference temperature for ending the heat storage use operation described later, an abnormal lower limit temperature t3 that becomes a reference temperature for switching from the heat storage use mode to the normal mode as described later, and the like. ing.

  Next, the operation in the normal mode will be described with reference to FIG. In this mode, in the operation in the normal mode, the floor heating apparatus body 2 (the heat source machine 12 and the thermal valve 22) is in the normal cycle period TS (in other words, also referred to as a duty ratio control period controlled by the duty ratio). Is controlled as a cycle. When the normal cycle period TS (duty ratio control period) is set to, for example, 20 minutes and the duty ratio is, for example, 1: 1, the on-state operation time TX is 10 minutes, and the off-state stop time TY is 10 minutes. The normal cycle period TS is repeatedly performed.

  Next, the operation in the heat storage utilization mode will be described with reference to FIG. In this mode, in the operation in the heat storage use mode, the floor heating apparatus main body 2 (the heat source unit 12 and the thermal valve 22) is controlled with the remaining heat cycle period TV as one cycle, and the first half of the remaining heat cycle period TV is the normal mode. Is the normal cycle period TS (that is, the duty ratio control period), and the latter half is the remaining heat utilization period TW. In the normal cycle period TS (duty ratio control period), the duty cycle is the same as the normal cycle period TS in the normal mode operation. When the ratio control is performed, for example, when the duty ratio is 1: 1, the operation time TX in the on state is 10 minutes, and the stop time TY in the off state is 10 minutes. In addition, the remaining heat use period TW is a period in which the remaining heat is heated using the heat stored in the housing portion (configured from the floor, side walls, ceiling, and the like) that defines the indoor space 6 during the heating operation. During this period, the floor heating apparatus body 2 is deactivated, and such a residual heat cycle period TV (normal cycle period TS + remaining heat use period TW) is repeatedly performed.

  This floor heating apparatus is controlled to operate as follows, for example. Referring mainly to FIGS. 1, 3 and 6, in order to operate the floor heating apparatus, the power switch 32 of the operation remote controller 30 may be turned on (step S1). Then, the time measuring means 62 of the control means 4 starts time measurement (step S2). When operating by operating the power switch 32, the process proceeds from step S3 to step S4, and the operation mode setting means 52 of the control means 4 sets the normal mode based on the operation command from the operation remote controller 30, and the operation control means. 50 operates the floor heating apparatus main body 2 in the normal mode as shown in FIG. When the power switch 32 is turned off during the operation in the normal mode, the process proceeds from step S6 to step S7, and the operation of the floor heating apparatus is completed.

  If the heat storage use mode switch 34 is operated after turning on the power switch 32 (or the heat storage use mode switch 34 is operated during the operation in the normal mode), the process proceeds from step S3 (or step S5) to step S8. Then, until a predetermined time (for example, set to about 2 to 4 hours) elapses after the time measuring means 62 starts measuring time, the process proceeds from step S8 to step S9 to step S10, and the normal mode operation is performed. The operation in the heat storage use mode, which will be described later, is not performed until this predetermined time has elapsed. If the power switch 32 is turned off during the operation in the normal mode, the process proceeds from step S9 to step S11, and the operation of the floor heating apparatus is completed.

  When the power switch 32 is turned on to start the heating operation, the floor heating apparatus main body 2 (the heat source unit 12 and the thermal valve 22) is operated, and the hot water generated by the heat source unit 12 is heated by the hot water tube of the floor heating panel 8. The floor heating panel 8 is warmed by the heat of the hot water circulated through the circulating water 10, and the indoor space 6 (heating target area) is warmed from the surface of the floor heating panel 8 thus warmed. 8 and its upper space are heated. And when it heats in this way, the heat of the floor heating panel 8 and the indoor space 6 is transmitted to the frame part (namely, a floor part, a side wall part, a ceiling part, etc.) of the building which defines the indoor space 6, and this takes Heat is stored in the housing. The heat storage in the housing portion is gradually performed, and when a predetermined time has elapsed from the start of the heating operation, sufficient heat is stored in the housing portion (in other words, the temperature is substantially the same as the temperature of the indoor space 6). The heat stored in the part can be used.

  For this reason, the operation in the normal mode is performed until the predetermined time elapses from the start of the heating operation, and after the predetermined time has elapsed, the operation of the floor heating device in the heat storage use mode is permitted. Alternatively, when the operation in the heat storage use mode is selected in step S5), the process proceeds to step S12, and the floor heating apparatus is controlled in the heat storage use mode. That is, the operation mode setting means 52 of the control means 4 sets the heat storage use mode command based on the heat storage use mode command from the heat storage use mode switch 34 of the operation remote controller 30, and the operation control means 50 is as shown in FIG. The floor heating apparatus main body 2 (the heat source machine 12 and the thermal valve 22) is controlled to operate in the heat storage use mode.

  Referring also to FIG. 7, when the operation in the heat storage use mode is started, the remaining heat cycle operation is started (step S13), and in the normal cycle period TS (duty ratio control period) in the first half of the remaining heat cycle period TV, As described above, the duty ratio control is performed on the heating apparatus main body 2. After the duty ratio control is completed, it is determined whether or not the heat storage use operation is performed in the second half of the remaining heat use period TW.

  In this embodiment, when the normal cycle period TS (duty ratio control period) ends, the temperature comparing means 56 detects the temperature of the indoor space 6 (detected temperature of the temperature sensor 46) and the remaining heat lower limit temperature stored in the memory means 64. If the temperature of the indoor space 6 is equal to or higher than the remaining heat lower limit temperature t2 by comparing with t2, the process moves from step S14 to step S15 to step S16, where the stored heat utilization operation is performed using the heat stored in the housing part. Is done. This heat storage use operation is performed until the temperature of the indoor space 6 is further lowered from the remaining heat lower limit temperature t2, and when the temperature of the indoor space 6 is thus reduced, the heat storage use operation is completed as shown in FIG. One cycle of the residual heat cycle period TV is completed, the process returns from step S15 to step S17 through step S13, the next residual heat cycle period TV is entered, and the floor heating apparatus body 2 is operated and controlled in the same manner as described above. Thus, the energy saving operation of the heating device can be performed by performing the heat storage use operation using the heat stored in the housing part.

  Further, when the normal cycle period TS (duty ratio control period) ends, if the temperature of the indoor space 6 is lower than the remaining heat lower limit temperature t2 (see FIG. 7), the process proceeds from step S15 to step S17. The comparison means 56 compares the temperature of the indoor space 6 (detected temperature of the temperature sensor 46) with the abnormal lower limit temperature t3 stored in the memory means 64, and when the temperature of the indoor space 6 is equal to or higher than the abnormal lower limit temperature t3, Returning from step S17 to step S13, the heat storage utilization operation is not performed, and the operation proceeds to the next residual heat cycle period TV, where the floor heating apparatus body 2 is operated and controlled in the same manner as described above. The temperature of the indoor space 6 can be prevented from being abnormally lowered.

  Furthermore, when the temperature of the indoor space 6 is lower than the abnormal lower limit temperature t3 when the duty ratio control ends (see FIG. 7), the process proceeds from step S17 to step S18, where the abnormal temperature decrease determination means 57 It is determined that the temperature of the indoor space 6 has suddenly decreased and is in a cooled state, and an abnormal temperature decrease is determined. Based on this determination, an abnormal temperature decrease signal is generated, and the mode switching means 54 provides the abnormal temperature decrease signal. Based on the above, the heat storage use mode is switched to the normal mode (step S19), and the process returns to step S4 to operate the floor heating apparatus body 2 in the normal mode as described above. For example, when a large amount of cold air flows into the indoor space 6 by opening windows, doors, etc. during operation in the heat storage use mode, the temperature of the indoor space 6 suddenly decreases due to the cold air flowing in, so that the temperature is lower than the abnormal lower limit temperature t3. When the temperature decreases and the temperature drops in this way, the operation is switched from the heat storage utilization mode operation to the normal mode operation.

  When the power switch 32 is turned off during the normal cycle period TS (duty control period) during the preheating cycle operation, the process proceeds from step S14 to step S20 to step S21, and the operation of the floor heating apparatus is completed. Further, when the power switch 32 is turned off during the heat storage use operation during the preheating cycle operation, the process proceeds from step S16 to step S22 to step S23, and the operation of the floor heating apparatus is completed.

  Next, with reference to FIGS. 8-10, the floor heating apparatus of 2nd Embodiment is demonstrated. In this 2nd Embodiment, it is comprised so that the remaining heat utilization time TW may be set according to the heat storage state stored in the housing part of the heating target area.

  In FIG. 8, the control means 4A in the floor heating apparatus of the second embodiment includes a remaining heat utilization time setting means 72 that calculates and sets the remaining heat utilization time TW as described later, and this remaining heat utilization time calculation. The remaining heat utilization time TW set by the means 72 is registered in the memory means 64A. The other configuration of the floor heating device in the second embodiment is substantially the same as that of the first embodiment described above, and the basic configuration of the floor heating device is substantially the same as the configuration shown in FIGS. 1 and 2. Further, the configuration of the control system is substantially the same as the configuration shown in FIG.

  The floor heating apparatus according to the second embodiment is controlled for operation as follows, for example. In the following description of the control, the description will focus on the parts that are different from the control in the first embodiment. Referring to FIGS. 9 and 10 together with FIG. 8, the contents of steps S31 to S42 in the control of the second embodiment are substantially the same as the contents of steps S1 to S22 in the first embodiment described above. Since it is the same, those explanations are omitted and will be explained from the time when the residual heat cycle operation is started.

  When the remaining heat cycle operation in the heat storage use mode is started in step S43, as described above, the floor heating apparatus main body 2 is as described above in the normal cycle period TS (duty ratio control period) in the first half of the remaining heat cycle period TV. After the duty ratio control is completed, it is determined whether or not the heat storage use operation is performed in the remaining heat use period TW.

  In this embodiment, when the normal cycle period TS (duty ratio control period) ends, the temperature comparing means 56 detects the temperature of the indoor space 6 (detected temperature of the temperature sensor 46) and the remaining heat lower limit temperature stored in the memory means 64. If the temperature of the indoor space 6 is equal to or higher than the remaining heat lower limit temperature t2 by comparing with t2, the process moves from step S44 to step S45 to step S46, where the stored heat using operation is performed using the heat stored in the housing part. In this way, the heat storage use operation is performed, and the time of the residual heat use period TW (that is, the residual heat use time) is set.

  That is, when the heat storage use operation is started, the time measuring means 60 starts timekeeping (step S47), and this heat storage use operation is performed until the temperature of the indoor space 6 decreases to the remaining heat lower limit temperature t2, and the indoor space 6 When the temperature decreases to the remaining heat lower limit temperature t2, the process proceeds from step S48 to step S49, the heat storage use operation ends, the time measurement by the time measuring means 62 ends, and the remaining heat utilization time setting means 72 measures the time measured by the time measuring means 60. Is set as the time of the remaining heat utilization period TW, and the set remaining heat utilization time is registered in the memory means 64A. Thereafter, the process proceeds to step S51, and the continuous remaining heat cycle operation using the remaining heat utilization time is performed.

Is operated as described above in normal mode.

  When the continuous residual heat cycle operation is started, the process proceeds from step S57 to step S58, and the duty ratio control of the floor heating apparatus body 2 is performed in the normal cycle period as described above, and this normal cycle period TS (duty ratio control period). As described above, the temperature comparison means 56 compares the temperature of the indoor space 6 (the temperature detected by the temperature sensor 46) with the remaining heat lower limit temperature t2 stored in the memory means 64, and the indoor space 6 When the temperature of 6 is equal to or higher than the remaining heat lower limit temperature t2, the process proceeds from step S58 to step S59 to step S40, where a stored heat use operation is performed in which heat is stored using the heat stored in the housing portion. When the remaining heat utilization time set by the remaining heat utilization time setting means 72 is performed and the heat storage utilization operation is completed, the process starts from step S61. Return to S57, the continued residual heat cycle operation is repeatedly performed.

  Further, when the temperature of the indoor space 6 is lower than the remaining heat lower limit temperature t2 at the end of the normal cycle period TS (duty ratio control period), the process proceeds from step S59 to step S62, and the temperature comparison unit 56 A comparison is made between the temperature of the space 6 (the temperature detected by the temperature sensor 46) and the abnormal lower limit temperature t3 stored in the memory means 64, and if the temperature of the indoor space 6 is equal to or higher than the abnormal lower limit temperature t3, steps S62 to S42 are performed. Returning to step 3, the remaining heat utilization time is set again.

  Further, when the temperature of the indoor space 6 is lower than the abnormal lower limit temperature t3 at the time when the duty ratio control is finished, the process proceeds from step SS62 to step S63, and the abnormal temperature decrease determination means 57 determines the temperature of the indoor space 6 It is determined that the temperature has dropped rapidly and the temperature has cooled, and the mode switching means 54 switches from the heat storage use mode to the normal mode (step S64), and returns to step S34 to return to the floor heating device body 2 Is operated as described above in normal mode.

  Next, with reference to FIGS. 11-13, the floor heating apparatus of 3rd Embodiment is demonstrated. In this third embodiment, instead of providing the remaining heat utilization period TW after the normal cycle period TS, it is usual to consider the time for heating the remaining heat using the heat stored in the housing part of the heating target area. The duty ratio in the cycle period TS is configured to be changed to the heat storage utilization duty ratio.

  In FIG. 11, the control means 4 </ b> B in the floor heating apparatus of the third embodiment includes a heat storage use duty ratio calculation means 82 and a heat storage use duty ratio setting means 84. The heat storage use duty ratio calculation means 82 calculates the heat storage use duty ratio as described later, and the calculated heat storage use duty ratio is registered in the memory means 64B, and the heat storage use duty ratio setting means 84 performs this calculation. The set heat storage utilization duty ratio is set, and, as will be described later, in the continuous residual heat cycle operation, the remaining heat cycle operation using the set heat storage utilization duty ratio is performed. The other configuration of the floor heating device in the third embodiment is substantially the same as that of the first embodiment described above, and the basic configuration of the floor heating device is substantially the same as the configuration shown in FIGS. 1 and 2. Further, the configuration of the control system is substantially the same as the configuration shown in FIG.

  The floor heating apparatus in the third embodiment is controlled for operation as follows, for example. Referring to FIGS. 12 and 13 together with FIG. 11, the contents of steps S71 to 82 in the control of the third embodiment are substantially the same as the contents of steps S1 to S22 in the first embodiment described above. Since it is the same, those explanations are omitted and will be explained from the time when the residual heat cycle operation is started.

  When the remaining heat cycle operation in the heat storage use mode is started in step S83, the floor heating apparatus main body 2 is duty ratio controlled with the normal duty ratio as described above during the normal cycle period TS (duty ratio control period). After the ratio control is completed, it is determined whether the duty cycle is changed and the remaining heat cycle operation is continuously performed.

  In this embodiment, at the time when the normal cycle period TS (duty ratio control period) ends, the temperature comparison means 56 detects the temperature of the indoor space 6 (detected temperature of the temperature sensor 46) and the remaining heat lower limit temperature stored in the memory means 64B. If the temperature of the indoor space 6 is equal to or higher than the remaining heat lower limit temperature t2 by comparing with t2, the process proceeds from step S84 to step S85 to step S86, where the stored heat using operation is performed using the heat stored in the housing part. The heat storage use duty ratio is calculated in consideration of the time during which the heat storage use operation is performed.

  That is, when the heat storage use operation is started, the time measuring means 60 starts timekeeping (step S87), and this heat storage use operation is performed until the temperature of the indoor space 6 decreases to the remaining heat lower limit temperature t2, and the indoor space 6 When the temperature of the heat storage decreases to the remaining heat lower limit temperature t2, the process proceeds from step S88 to step S89, the heat storage use operation ends, the time measurement by the time measuring means 62 ends, and the heat storage use duty ratio calculation means 82 measures the time measured by the time measurement means 60. The heat storage utilization duty ratio is calculated as follows in consideration of time (step S90).

  For example, if one cycle period of the normal cycle period TS is 20 minutes, for example, and the duty ratio of the normal cycle period is 1: 1, the operation period TX ( The on-time is 10 minutes, and the non-operation time TY (off-state time) is 10 minutes. In such a duty ratio state, if the time keeping time TZ of the time measuring means 62 in the heat storage use operation is 5 minutes, for example, the remaining heat use duty ratio calculating means 82 is 10 minutes as the operation time TX ′, and the non-operation time TY. As 15 ′ (TY + TZ = 10 + 5 = 15), the heat storage utilization duty ratio is set to 2: 3.

  The heat storage use duty ratio calculated by the heat storage use duty ratio calculation means 82 is registered in the memory means 64B, and the heat storage use duty ratio setting means 84 sets the calculated heat storage use duty ratio instead of the duty ratio. (Step S91), the process proceeds to Step S92, and the continuous residual heat cycle operation using the heat storage utilization duty is performed.

  Further, when the temperature of the indoor space 6 is lower than the remaining heat lower limit temperature t2 at the end of the normal cycle period TS (duty ratio control period), the process proceeds from step S85 to step S93, and the temperature comparison unit 56 A comparison is made between the temperature of the space 6 (the temperature detected by the temperature sensor 46) and the abnormal lower limit temperature t3 stored in the memory means 64B, and when the temperature of the indoor space 6 is equal to or higher than the abnormal lower limit temperature t3, step S93 to step S83 are performed. Returning to step S3, the operation is controlled again in the same manner as described above without changing the heat storage utilization duty ratio, and the operation of the floor heating apparatus main body 2 is performed in the same manner as described above. This is done until

  Further, when the temperature of the indoor space 6 is lower than the abnormal lower limit temperature t3 at the time when the duty ratio control is finished, the process proceeds from step S93 to step S94, and the abnormal temperature decrease determining means 57 determines the temperature of the indoor space 6 It is determined that the temperature has dropped rapidly and the temperature has cooled down, and the mode switching means 54 switches from the heat storage use mode to the normal mode (step S95), and returns to step S74 to return to the floor heating apparatus body 2 Is operated as described above in normal mode.

  When the continuous residual heat cycle operation is started, the process proceeds from step S98 to step S99, and the duty ratio control of the floor heating apparatus body 2 using the heat storage utilization duty ratio is performed in the normal cycle period, and this normal cycle period TS (duty ratio) When the control period) ends, the temperature comparison means 56 compares the temperature of the indoor space 6 (the temperature detected by the temperature sensor 46) with the remaining heat lower limit temperature t2 stored in the memory means 64B, as described above. When the temperature of the indoor space 6 is equal to or higher than the residual heat lower limit temperature t2, the process returns from step S99 to step S100 and then returns to step S98, and the continuous residual heat cycle operation using this heat storage utilization duty ratio is repeatedly performed.

  Further, when the temperature of the indoor space 6 is lower than the remaining heat lower limit temperature t2 at the end of the normal cycle period TS (duty ratio control period), the process proceeds from step S100 to step S101, and the temperature comparison means 56 A comparison is made between the temperature of the space 6 (the temperature detected by the temperature sensor 46) and the abnormal lower limit temperature t3 stored in the memory means 64B, and if the temperature of the indoor space 6 is equal to or higher than the abnormal lower limit temperature t3, steps S101 to S83 are performed. The calculation of the heat storage utilization duty ratio is performed again and set.

  Further, when the temperature of the indoor space 6 is lower than the abnormal lower limit temperature t3 at the time when the duty ratio control is finished, the process proceeds from step S101 to step S102, and the abnormal temperature decrease determination means 57 determines the temperature of the indoor space 6 It is determined that the temperature has dropped rapidly and the temperature has cooled, and the mode switching means 54 switches from the heat storage use mode to the normal mode (step S103), and returns to step S74 to return to the floor heating apparatus body 2 Is operated as described above in normal mode.

However, the present invention is not limited to such a configuration. During the operation in the heat storage use mode (that is, in the normal cycle period TS and the residual heat use period TW), the temperature of the indoor space 6 is the abnormal lower limit temperature t3. When the temperature is lower than that, it may be determined that the abnormal temperature has decreased, and the heat storage use mode may be switched to the normal mode.
