In such a system heating apparatus, not only the temperature of the electric carpet is controlled by a temperature sensor provided on the electric carpet, but also the temperature data of the temperature sensor is taken in by an air conditioner, and the indoor temperature of the air conditioner is converted to the floor temperature of the electric carpet. The temperature is set appropriately.
In this case, the appropriate temperature is the temperature at which the person sitting on the carpet is considered to be the most comfortable by both the floor temperature and the indoor temperature, and the floor temperature and the indoor temperature are higher. In this case, it is too hot and wasteful power is consumed. On the other hand, when the temperature is low, the temperature is too cold.

In such a case, in the system heating device described above, the air conditioner takes in temperature data from the electric carpet. Since the indoor temperature is controlled by an air conditioner, reference temperature data cannot be obtained from two electric carpets having different set temperatures and floor temperatures, and reliable combined operation cannot be performed.

[0005] Therefore, a system heating method has been proposed in which the temperature of the electric carpet is controlled based on the temperature data on the air conditioner side during the combined operation so that the aforementioned thermal sensation becomes zero.

The above-mentioned thermal sensation 0 is experimentally and empirically obtained, and means that a comfortable feeling is obtained corresponding to each temperature of the room temperature by the air conditioner and each temperature of the electric carpet. I have.

However, in any of the above-described system heating, the temperature of the other appliance is controlled based on the temperature data of one appliance so that the thermal sensation becomes zero. In order to control the temperature of the air conditioner and the electric carpet based on the temperature set at this time, the power consumption of the air conditioner and the electric carpet is not considered at all, and the use of wasted electric power is not considered. Control.

According to the present invention, in a system in which an air conditioner and a heating device are operated in combination, a point at which the user is comfortable and the total energy consumption of each device is minimized is automatically controlled.

And an energy point at which the total energy consumption of the air conditioner and the heating device is minimized at a specific point, and the control by the energy point is performed by operating the automatic temperature setting means.

A second aspect of the present invention is that, when the automatic temperature setting means is operated, the room temperature controlled by the air conditioner and the temperature controlled by the heater are adjusted along each point of the comfortable temperature curve. And a slow control operation mode in which the control is performed in accordance with the energy point.

Here, the ideal temperature when the air conditioner and the electric carpet are operated together will be described in detail. The room temperature controlled by the air conditioner and the floor surface temperature controlled by the electric carpet are represented by the comfort temperature curve in FIG. 5, and this comfort temperature curve is obtained for each of the room temperature by the air conditioner and the temperature of the electric carpet. It is obtained by experimentally finding the comfortable point and connecting these preset points.If the room temperature is high, sufficient warmth can be obtained even if the floor surface temperature is low, and conversely, the room temperature is low. If the floor surface temperature is not raised, it will not be a comfortable temperature. For example, when the room temperature is (24 degrees), the floor surface temperature is (20 degrees) and comfortable (A point), and when the room temperature is (23 degrees), the floor surface temperature is (22 degrees) and comfortable. (Point B), and when the room temperature is (21 degrees), the floor surface temperature is (32 degrees)
Become comfortable. (G point). As described above, the room temperature and the floor surface temperature are experimentally measured, and the comfortable temperature at each temperature is represented by points (A) to (L). Call it a line. Of course, since the comfortable temperature varies among individuals, there may be a vertical width for each point. For example, at point (A), the room temperature may be (24 degrees) and the floor surface temperature may be (21 degrees), or the room temperature may be (23 degrees) and the floor surface temperature may be (23 degrees).

The power consumptions of the air conditioner (5) and the electric carpet (21) at the respective points (A) to (L) obtained by the comfortable temperature curves of FIG. 5 are represented by a bar graph of FIG. The shaded area in the middle indicates the power consumption of the air conditioner, and the plain area indicates the power consumption of the electric carpet. This graph shows that when the floor surface temperature is low, the power consumption of the electric carpet is small and the power consumption of the air conditioner is large. Conversely, when the floor surface temperature is high, the power consumption of the electric carpet is large and the power consumption of the air conditioner is small. In particular, at point (G), the total power consumption of the air conditioner and the electric carpet is the smallest, and the energy is an ideal energy point in terms of comfort and economy.

As described above, the data of these comfortable temperature curves are stored in advance in the operation storage circuit (32), and the air conditioner (5) and the electric carpet (2) are stored in advance.
During the combined operation of 1), the floor surface temperature of the electric carpet is automatically set based on the room temperature data of the remote controller (9) based on this data.

Next, the operation will be described.

The air conditioner (5) and the remote controller (9) are installed in one room as a set. The remote controller (9) transmits room temperature data and set temperature data at 5-minute intervals. The heating amount is controlled by comparing the set temperature with the room temperature based on the transmitted data.

FIG. 7 is a flowchart of the remote control (9).
FIG. 8 is a flowchart of the air conditioner (5), and FIG. 9 is a flowchart of the electric carpet (21).

First, a case where the air conditioner (5) and the electric carpet (21) are operated together will be described with reference to FIG.
A power switch (not shown) of the remote controller (9) is turned on (S1), an operation start signal is transmitted (S2), and a desired room temperature (for example, 22 ° C.) is operated by operating the temperature setting buttons (19) and (19). Set. Thereafter, it is determined whether or not the automatic switch (20) is operated to enter the saving operation mode (S3).
3) reads the temperature (22 ° C.) set by the temperature setting circuit (12) (S4). If there is no change in the set temperature (S5), the room temperature sensor (10) uses the current room temperature (now, for example, 20). 0.5 ° C) (S
6). An output circuit (13) which takes in room temperature data of the room temperature detecting circuit (11) compares the temperature data of the room temperature detecting circuit (11) with the set temperature data of the temperature setting circuit (12) and outputs the transmission element. From (16), the current room temperature data and the set temperature data are transmitted to the air conditioner (5) (S7). If the user changes the set temperature of the air conditioner (5) in the middle (S8), it is determined in step (S5) that the set temperature has changed, and the set temperature data after the change and the current room temperature data are determined. The data is transmitted (S7).

Then, the set temperature data (22 ° C.) and the current room temperature data (20.5 ° C.) by the transmitting element (16) of the remote controller (9) are received by a receiving element (not shown). The operation of the air conditioner (5) is shown in FIG.
This will be described in a chart. The arithmetic circuit (7) of the air conditioner (5) receives the operation start signal, the room temperature data and the set temperature data via the input circuit (6) by the receiving element (35) (S9) (S10), and receives the room temperature (20.5). ° C) is lower than the set temperature (22 ° C), the air conditioner (5) is turned on (S11) (S12), and a heater or the like is energized to raise the room temperature to the set temperature. Eventually, when the room temperature rises and reaches the set temperature (22 ° C.), the air conditioner (5) is turned off (S11) (S13), and the power supply to the heater and the like is stopped.
Thereafter, the air conditioner (5) receives the room temperature data and the set temperature data from the remote controller (9) and maintains the temperature (22 ° C.) set by the remote controller (9).

Thereafter, the room temperature data transmitted from the remote controller (9) every 5 minutes is obtained from the room temperature (20.5 ° C.) data at the start of the operation of the air conditioner (5), and then the current room temperature data ( 22.degree. C.), and transmits room temperature data (22.degree. C.) unless there is a change in the set temperature by the remote controller (9) or a significant change in the outside temperature.

The transmitting element (1) of the remote controller (9) described above.
Only the room temperature data according to 6) is received every 6 minutes by the reception sensor (2
The operation of the electric carpet (21) received by 7) will be described with reference to the flowchart of FIG. The electric carpet (21) turns on the power switch (26) in advance for the purpose of operating together with the air conditioner (5) (S1).
4) A changeover switch (not shown) provided on the controller (23) of the electric carpet (21) is set to the "combined operation" side.

The arithmetic circuit (33) receives the room temperature data (20.5 ° C.) at the time of starting the operation of the air conditioner (5) from the remote controller (9) via the input circuit (34) (S15). This room temperature data (20.5 ° C.) is set (S16), and a point (I) obtained from the comfort temperature curve previously input to the arithmetic storage circuit (32) is set (S17). From the point (I), the floor surface temperature is set to (36 ° C.) (S1)
8). The floor surface temperature of the electric carpet (21) at which a comfortable temperature corresponding to the room temperature (20.5 ° C.) is obtained is (36 ° C.), but is detected by the temperature sensor (28) (S19). Floor surface temperature of (36 ℃)
If higher, the heater (22) is turned off (S20).
(S21) If low, the heater (22) is turned on (S22). Thereafter, the floor surface temperature is maintained at (36 ° C.) while the room temperature does not fluctuate at (20.5 ° C.).

As described above, the room temperature at the start of the combined operation is (2)
0.5 ° C) air conditioner (5) and electric carpet (2
The operation of 1) is actually performed. Since the room temperature is set to (22 ° C.) by the remote controller (9), the room temperature gradually rises by the operation of the air conditioner (5). For example, when the room temperature rises from (20.5 ° C.) to (21 ° C.), as described above, the room temperature data is transmitted to the air conditioner (5) every 5 minutes by the transmitting element of the remote controller (9) and the operation is performed. At the same time as the reception sensor (2
The electric carpet (21), which receives the room temperature data (21 ° C.) every 6 minutes according to 7), sets a point (G) obtained from the comfortable temperature curve and sets the floor surface temperature to (32).
° C).

The point (G) at this time is the energy point at which the total power consumption of the air conditioner (5) and the electric carpet (21) is the smallest as described above, and a comfortable and economical driving operation is performed. Thereafter, the room temperature further rises (21.5 ° C.), and the transmitting element transmits the current room temperature data during the period of 5 minutes, and the electric carpet (21) receiving the data during the period of 6 minutes, A point (E) obtained from the comfortable temperature curve is set, and the floor surface temperature is (28 ° C.). Similarly, when the room temperature reaches (22 ° C.) set by the remote controller (9), the electric carpet (2)
In 1), the point (D) obtained from the comfort temperature curve is set, and the floor surface temperature becomes (26 ° C.). Thereafter, unless the set temperature is changed by the remote controller (9), the air conditioner (5) sets the set temperature (22). ° C), and the electric carpet (21) obtains a comfortable temperature by setting the floor surface temperature to (26 ° C).

In this way, until the room temperature reaches the set temperature of the air conditioner (5), the floor surface temperature of the electric carpet (21) is determined based on the points obtained from the comfortable temperature curve for each temperature according to the change in the room temperature. After the room temperature reaches the set temperature of the air conditioner (5), the floor surface temperature of the electric carpet (21) is controlled by the points obtained from the comfortable temperature curve to always obtain the comfortable temperature.

The reception cycle of the electric carpet (21) by the reception sensor (27) every 6 minutes is longer than 5 minutes because the signal from the remote controller (9) is transmitted every 5 minutes. To accurately receive the signal from the remote control (9).

Next, based on the flowchart of FIG. 7.8.9, the set temperature of the air conditioner (5) at the above point (D) is (22 ° C.) and the floor surface temperature of the electric carpet (21) is (26 ° C.). ) During the combined operation controlled by
Hereinafter, a description will be given of a case where economical heating is performed.

When the automatic switch (20) is operated to automatically set the temperature of the air conditioner (5) to (21 ° C.) and transmit the set temperature data (21 ° C.), the mode shifts to the saving operation mode (FIG. 7). .S3) and the automatic switch (2
The operation signal of (0) is output to the data storage means (14) through the temperature setting circuit (12), and the data storage means receiving the operation signal is output to the temperature setting circuit (12) to perform the slow control operation mode. The process proceeds to (S24 in FIG. 7.), and is output so that the room temperature by the air conditioner (5) becomes (21 ° C.) (S25 in FIG. 7.). The air conditioner (5) does not shift from the current set temperature to the set temperature (21 ° C.) in the saving operation mode at once, but operates the automatic switch (20) in the slow control operation mode. Also, the set temperature of the air conditioner (5) is controlled by a temperature along a point obtained from a comfortable temperature curve. That is, the remote control (9)
The set temperature data is gradually changed from the set temperature to the target set temperature, and the data of each set temperature is transmitted every five minutes together with the room temperature data at that time to control the air conditioner (5). . Therefore, the set temperature is (2

When the temperature is below (21.5 ° C.), it is turned on (FIG. 8. S12).
When the room temperature is stabilized at (21.5 ° C.), the floor surface temperature of the electric carpet (21) is set to (28 ° C.) at the point (E) (FIG. 9. S15 to S18). Furthermore, the set temperature is lowered to (21.2 ° C) and the room temperature is also (21.2 ° C)
