Is set at room temperature and floor surface temperature at the middle of the point. Then, the heating means 2 and the floor heating means 3 are operated under these conditions. For example, when the detection middle room temperature is 19 ° C., the detection floor temperature is 22 ° C., and the current point in FIG. 5 is P1, the point P2 closest to the point P1 in the comfort area is the middle room temperature of 20 ° C. The floor temperature is 25 ° C. Therefore, in this case, the heating temperature of the heating means 2 is set to 20 ° C., and the heating temperature of the floor heating means 3 is set to 25 ° C.

  If the determination (7) is affirmative, the heating temperature of the heating means 2 is increased by a predetermined temperature T12, and the heating means 2 is operated in this state. In Table 1, T12 = 1 (° C.) is set. Further, the floor heating means is maintained in the operating state after the previous determination.

Moreover, the floor heating means 3 is maintained in the operating state after the previous determination. In Table 1, T13 = 2 (° C.) is set.

  If the determination (10) is affirmative, the air blowing means 4 is agitated and the floor heating means 3 is maintained in the operating state after the previous determination. Moreover, the heating temperature of the heating means 2 is set to an expected temperature, and the heating means 2 is operated in this state. The predicted temperature is calculated based on the information detected by the room temperature detection means 8 and changes according to the temperature environment in the target room 1 assumed by the operation of the blower means 4. Specifically, it is determined based on the detection upper part room temperature, the detection intermediate part room temperature, and the detection lower part room temperature, and consists of an average value of these room temperatures. The operation of the air blowing means 4 may be either a downward operation or an upward operation. If both determination (5) and determination (10) are affirmed, either the control according to determination (5) or the control according to determination (10) is performed according to a predetermined priority order. Executed.

  If the determination (11) is affirmative, the heating temperature of the heating means 2 is increased according to the difference between the detected wall surface temperature and the detected intermediate room temperature, and the heating means 2 is operated in this state.

Moreover, the floor heating means 3 is maintained in the operating state after the previous determination.

  In addition, when there are a plurality of determinations to be affirmed among the determinations (1) to (11), the control method is changed according to each affirmed determination according to a preset order, and finally changed. The heating means 2, the floor heating means 3, and the air blowing means 4 are controlled by the control method.

  For example, the target comfort level is 0, the detection comfort level is -0.8, the detection upper room temperature is 26 ° C., the detection intermediate room temperature is 20 ° C., the detection lower room temperature is 20 ° C., the detection floor surface temperature is 20 ° C., and the current heating It is assumed that the heating temperature (set temperature) of the means 2 is 22 ° C. and the determinations (6), (9), and (10) are affirmed. In this case, it is determined that the air blowing means 4 is agitated according to the determination (10). Further, the heating temperature of the heating means 2 is first changed to 20 ° C. according to the determination (6). Next, the predetermined temperature T13 (2 ° C.) is increased according to determination (9), and the temperature is changed to 22 ° C. Next, according to the judgment (10), the heating temperature of the heating means 2 is set to an expected temperature of 22 ° C. (= (26 ° C. + 20 ° C. + 20 ° C.) / 3). Therefore, in this case, the heating means 2 is operated at a heating temperature of 22 ° C. Further, the floor heating means 3 is set to 26 ° C. according to the determination (6).

  In the heating system of the present embodiment, the control comfort based on the determinations (1) to (11) is performed by cooperatively controlling the three members obtained by adding the air blowing means 4 to the heating means 2 and the floor heating means 3, and the detected comfort level is set as the target comfort level. Can be approached. For this reason, during the cooperative control operation, the air in the target chamber 1 can be stirred up and down by the air blowing means 4 as in the control based on the determination (10), so that the temperature in the target chamber 1 can be made uniform. Therefore, while maintaining the comfort level in the target room 1 close to the target comfort level, it is possible to create a temperature environment that is comfortable for the user over the entire area in the target room 1, and the heating means 2 and the floor heating means 3 Energy consumption can be reduced.

  Further, in the control based on the determination (10), the blowing unit 4 is controlled based on the temperature difference between the detected upper room temperature and the detected lower room temperature, and the temperature environment in the target chamber 1 assumed by the control of the blowing unit 4 Accordingly, each of the heating means 2 and the floor heating means 3 is controlled. By this control, when a temperature difference occurs between the detection upper room temperature and the detection lower room temperature, the air in the target chamber 1 is stirred up and down by the blowing means 4 so that the temperature in the target chamber 1 can be made uniform. Further, in this case, since the operation of the heating unit 2 is controlled according to the temperature environment in the target chamber 1 assumed by the control of the blowing unit 4, energy consumption due to the operation of the heating unit 2 can be further suppressed.

  Further, in the control based on the determination (6), the heating unit 2 and the floor heating unit 3 are controlled so that the combination of the detection intermediate part room temperature and the detection floor surface temperature is within a predetermined range set in advance. For this reason, both the room temperature and the floor surface temperature of the target room 1 can be further made suitable for the user.

  Even if the detected comfort level is close to the target comfort level, if there is a temperature difference between the room temperature and the wall surface temperature, a user near the wall surface of the target room 1 feels cold or hot due to radiation from the wall surface. However, in the control based on the determination (11), the heating unit 2 is controlled so that the temperature difference between the detected wall surface temperature and the detected intermediate part temperature is small. For this reason, the discomfort due to the radiation can be made difficult to occur.

  Further, in the control based on the determination (5), when the detection outdoor air temperature becomes higher than a value obtained by adding a predetermined temperature to the detection intermediate part room temperature, the outdoor air intake means including the blower means 4 is used. Control to take outdoor air into the target room 1 is performed. Thereby, outdoor air whose temperature is higher than the room temperature of the target chamber 1 can be taken into the target chamber 1 to increase the temperature in the target chamber 1, and energy consumption can be further suppressed. In the present embodiment, the outdoor air is taken into the target chamber 1 when the detection outdoor air temperature becomes higher than a value obtained by adding a predetermined temperature set in advance to the detection intermediate room temperature. However, the outdoor air may be taken into the target chamber 1 by the blowing means 4 when the detection outdoor air temperature becomes higher than the detection intermediate room temperature. In the present embodiment, the outdoor air intake means is configured by the air blowing means 4, but an outdoor air intake means may be provided separately from the air blowing means 4. Further, in the control based on the determination (5) and the determination (6) described above, the heating means 2, the floor heating means 3, and the air blowing means 4 are controlled based on the detected intermediate room temperature. Instead, the average value of the three of the detection middle part room temperature, the detection upper part room temperature, and the detection lower part room temperature may be adopted.

  In addition, a cooperative control mode for cooperatively controlling the heating means 2, the floor heating means 3, and the air blowing means 4, and an individual operation mode for individually operating each of the heating means 2, the floor heating means 3, and the air blowing means 4, An operation means 25 for switching between the cooperative control mode and the individual operation mode is provided. For this reason, it can switch to individual operation mode by the operation means 25, and each of the heating means 2, the floor heating means 3, and the ventilation means 4 can be utilized independently.

  In the present embodiment, the comfort level is a PMV value, but other comfort indexes such as ET (Effective Temperature: effective temperature) may be detected as the comfort level. In the present embodiment, the target comfort level is determined based on the set comfort level and the detection information of the human body detection unit 12, but the set comfort level may be set as the target comfort level. Moreover, as long as the heating means 2 heats the upper part of the object room 1, you may comprise by other heating means, such as a radiant heating panel.
