Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system heating device for operating an air conditioner such as an air conditioner and a heating device such as an electric carpet together in one indoor living space.

[0002]

2. Description of the Related Art Conventionally, for example, the one in which an air conditioner and an electric carpet are operated together in one indoor living space is disclosed in, for example, Japanese Patent Laid-Open No.
-31655.

In such a system heating device, not only the temperature of the electric carpet is controlled by the temperature sensor provided on the electric carpet, but also the temperature data of the temperature sensor is taken in by the air conditioner so that the room temperature of the air conditioner becomes the floor temperature of the electric carpet. The temperature is set to match.
The appropriate temperature in this case is the temperature at which the person sitting on the carpet is most comfortable with both the floor temperature and the room temperature, and the floor temperature and the room temperature are high. In this case, it means that it is too hot and consumes useless electric power, and conversely, when each temperature is low, it is too cold, so the position of so-called thermal sensation 0, which is neither hot nor cold, is determined.

However, when a large number of people enter one indoor living space, two electric carpets may be used. In such a case, in the above-mentioned system heating device, the air conditioner takes in temperature data from the electric carpet. Since the indoor temperature is controlled by the air conditioner, the reference temperature data cannot be obtained from the two electric carpets having different set temperatures and floor temperatures, and reliable combined operation cannot be performed.

For this reason, a system heating method has been proposed in which the temperature of the electric carpet is controlled on the basis of the temperature data on the air conditioner side during the combined operation so that the above-described thermal sensation becomes zero.

The above-mentioned thermal sensation 0 is obtained experimentally and empirically, and means that the user feels comfortable according to each temperature of the room temperature by the air conditioner and each temperature of the electric carpet. There is.

[0007]

However, in any of the above-described system heating, the temperature of the other appliance is controlled so that the thermal sensation is zero based on the temperature data of the one appliance. Therefore, in order to control the temperature of the air conditioner and the electric carpet based on the temperature set at this time, no consideration is given to the power consumption of the air conditioner and the electric carpet, and the feeling of heat and cold is 0 while using the unnecessary power. Was being controlled.

According to the present invention, in a case where an air conditioner and a heating device are operated together, a point where the user is comfortable and the total energy consumption of each is minimized is automatically set and controlled.

[0009]

The first aspect of the present invention is to provide an air conditioner for heating an indoor living space, a heating device for directly heating a human body by conduction heat, radiant heat or convection heat, and the air conditioner and the heating device. During the combined operation of
Environmental temperature control means for controlling the room temperature of the air conditioner and the temperature of the heating device by a correlation based on a preset comfortable temperature curve, and the room temperature of the air conditioner and the temperature of the heating device are automatically interlocked with each other. The comfortable temperature curve connects points set in advance for each temperature of room temperature controlled by the air conditioner and each temperature controlled by the heating device. The energy point of the total energy consumption of the air conditioner and the heating device obtained at the specific point is the minimum, and the control by the energy point is executed by the operation of the automatic temperature setting means.

A second aspect of the present invention is that when the automatic temperature setting means is operated, the temperature of room temperature controlled by the air conditioner and the temperature controlled by the heating device are set along each point of the comfort temperature curve. It is provided with a slow control operation mode in which the control is performed in accordance with the energy point and the control is shifted to the control by the energy point.

[0011]

First, during the combined operation of the air conditioner and the heating device, the automatic temperature setting means automatically selects the energy point of the comfortable temperature curve that minimizes the total energy consumption of the air conditioner and the heating device. Run.

Secondly, at the time of operating the automatic temperature setting means, the control shifts to the energy point control while controlling along each point of the comfortable temperature curve by the slow control operation mode.

Here, the ideal temperature during the combined operation of the air conditioner and the electric carpet 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 temperature of the room temperature by the air conditioner and the temperature of the electric carpet. It was obtained by experimentally finding a 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 on the contrary, the room temperature is low. If the floor surface temperature is not raised, the temperature will not be comfortable. 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. (B point), and if the room temperature is (21 degrees), the floor surface temperature is (32 degrees).
And become comfortable. (G point). As described above, the room temperature and the floor surface temperature are experimentally measured, and the comfortable temperature for each temperature is represented by points (A) to (L). Call it a line. Of course, since the comfortable temperature varies from person to person, there may be a vertical width for each point. For example, at the 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 consumption of the air conditioner (5) and the electric carpet (21) at the points (A) to (L) obtained from the comfort temperature curve of FIG. 5 is represented by the bar graph of FIG. The shaded area in the figure shows the power consumption of the air conditioner and the plain area shows 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, and 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. Especially at point (G), the total power consumption of the air conditioner and the electric carpet is the smallest, which is an ideal energy point in terms of comfort and economy.

As described above, the data of these comfortable temperature curves are previously stored in the arithmetic storage circuit (32), and the air conditioner (5) and the electric carpet (2) are stored.
During the combined operation 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, and the remote controller (9) transmits room temperature data and set temperature data at intervals of 5 minutes, and the air conditioner (5) uses this data. Based on the transmitted data, the set temperature and the room temperature are compared to control the heating amount.

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

First, the case of operating the air conditioner (5) and the electric carpet (21) 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 temperature setting buttons (19) and (19) are operated to set a desired room temperature (for example, 22 ° C.). Set. Then, it is judged whether the automatic switch (20) is operated to enter the saving operation mode (S3). If there is no such operation, the output circuit (1
3) reads the temperature (22 ° C.) set by the temperature setting circuit (12) (S4) and if there is no change in the set temperature (S5), the room temperature sensor (10) reads the current room temperature (for example, 20 0.5 ° C) is detected (S
6). The output circuit (13) incorporating the 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) to transmit the transmitting element. From (16), the present 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) on the way (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 changed. Data is transmitted (S7).

Then, the set temperature data (22 ° C.) by the transmitting element (16) of the remote controller (9) and the present room temperature data (20.5 ° C.) are received by the receiving element (not shown). The operation of the air conditioner (5) is shown in FIG.
Describe by 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 the room temperature (20.5). Since (.degree. C.) is lower than the set temperature (22.degree. C.), the air conditioner (5) is turned on (S11) (S12) and the 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.
After that, 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).

After that, the room temperature data transmitted from the remote controller (9) every 5 minutes is changed from the room temperature (20.5 ° C.) data at the start of operation of the air conditioner (5) to the current room temperature data ( 22 ° C.), and room temperature data (22 ° C.) is transmitted unless the set temperature is changed by the remote controller (9) or the outside air temperature is largely changed.

The transmitter element (1) of the remote controller (9) described above.
Only the room temperature data from 6) is received every 6 minutes.
The operation of the electric carpet (21) received by 7) will be described with reference to the flowchart of FIG. The electric carpet (21) has the power switch (26) turned on in advance for the purpose of combined use with the air conditioner (5) (S1
4), the 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 start of operation of the air conditioner (5) from the remote controller (9) through the input circuit (34) (S15). The room temperature data (20.5 ° C.) is set (S16), and the point (I) obtained from the comfortable temperature curve previously input to the arithmetic storage circuit (32) is set (S17). From the point (I), set the floor surface temperature to (36 ° C) (S1
8). At this time, the floor temperature of the electric carpet (21), which provides a comfortable temperature corresponding to the room temperature (20.5 ° C.), is (36 ° C.), which is detected by the temperature sensor (28) (S19) Floor surface temperature is (36 ℃)
If higher, turn off the heater (22) (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).

Above, the room temperature at the start of the combined operation is (2
Air conditioner (5) and electric carpet (2) at 0.5 ℃
Regarding the operation of 1), since the room temperature is actually set to (22 ° C.) by the remote controller (9), the room temperature is gradually raised by the operation of the air conditioner (5). For example, when the room temperature rises from (20.5 ° C) to (21 ° C), the room temperature data is transmitted to the air conditioner (5) every 5 minutes by the transmitting element of the remote controller (9) as described above, and the operation is performed. At the same time that the above-mentioned reception sensor (2

℃).

At this time, the point (G) 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 saving operation is performed. After that, the room temperature rises further (21.5 ° C.), the transmitting element transmits the current room temperature data during the period of 5 minutes, and the electric carpet (21) which receives the data during the period of 6 minutes is The 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 comfortable 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.), the electric carpet (21) obtains a comfortable temperature with the floor surface temperature (26.degree. 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 based on the points obtained from the comfortable temperature curve for each temperature according to the change in room temperature. And 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 reception sensor (27) of the electric carpet (21) every 6 minutes is longer than 5 minutes since the signal from the remote controller (9) is transmitted every 5 minutes. This is because the signal from the remote controller (9) is correctly received by setting to.

Next, based on the flow chart of FIG. 7.8.9, the set temperature of the air conditioner (5) at the above-mentioned point (D) is (22 ° C.) and the floor surface temperature of the electric carpet (21) is (26 ° C.). ) During the combined operation controlled by
The following describes the case of economical heating.

When the automatic switch (20) is operated to automatically set the set temperature of the air conditioner (5) to (21 ° C.) and the set temperature data (21 ° C.) is transmitted, the mode shifts to the saving operation mode (FIG. 7). .S3) and automatic switch (2
The operation signal 0) is output to the data storage means (14) via the temperature setting circuit (12), and the data storage means receiving this is output to the temperature setting circuit (12) to output the slow control operation mode. While shifting to (Fig. 7. S24), the room temperature by the air conditioner (5) is output so as to be (21 ° C) (Fig. 7. S25). In the slow control operation mode described above, 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 when the automatic switch (20) is operated. Also, the set temperature of the air conditioner (5) is controlled by the temperature along the point obtained from the comfortable temperature curve. That is, the remote controller (9)
The set temperature data according to is designed to gradually change the set temperature to the target set temperature, and each set temperature data is sent every 5 minutes together with the room temperature data at that time to control the air conditioner (5). . Therefore, the set temperature is (2
The air conditioner (5) receives this set temperature data (Fig. 8.S10) and compares the set temperature data with the room temperature (Fig. 8.S11). Above 21.5 ° C, turn off the air conditioner (5) (Fig. 8. S13),
It is turned on at (21.5 ° C) or lower (Fig. 8. S12).
When the room temperature stabilizes at (21.5 ° C.), the floor surface temperature of the electric carpet (21) is set to (28 ° C.) at point (E) (FIG. 9. S15 to S18). Furthermore, the set temperature is lowered to 21.2 ° C and the room temperature is also set to 21.2 ° C.
When it comes to point (F), the electric carpet (2
The floor surface temperature of 1) is set to (30 ° C). And
When the set temperature reaches the target set temperature (21 ° C), the room temperature also becomes (21 ° C), and the floor surface temperature of the electric carpet (21) is controlled to (32 ° C) based on the energy point (G).

(S3) to (S7) of FIG. (S24)
(S25) and (S10) to (S12) of FIG. (S1
3) and (S15) to (S21) of FIG. (S22) constitutes an environmental temperature control means.

FIG. 10 shows the operation of the air conditioner (5) and the electric carpet (21) independently, or when the operation of the electric carpet (21) is started during the operation of the air conditioner (5) and the operation of the electric carpet (21). It is a change characteristic view of room temperature and floor surface temperature based on the comfortable temperature curve at the time of combined operation when the operation of the air conditioner (5) is started, for example, the electric carpet (21) during operation of the air conditioner (5). When the room temperature at the start of the combined operation is (22 ° C) when the operation of the above is started and the floor surface temperature which is natural is (24 ° C), the above-mentioned × Select the point (D) of the comfortable temperature curve closest to the mark (dotted line arrow P) and set the temperature of the air conditioner (5) to (22
C.), the floor surface temperature of the electric carpet (21) becomes (22.degree. C.), and thereafter control is performed based on this point (D).

When the operation of the electric carpet (21) is started and the automatic switch (20) is operated during the operation of the air conditioner (5), the control is performed based on the point (D) and then the point (E). ． Control is performed based on the point (F), and then the room temperature of the air conditioner (5) is (21 ° C.) based on the energy point (G). The floor surface temperature of the electric carpet (21) is controlled to be (32 ° C).

Controlled by the floor surface temperature. For example, if the room temperature (23 ° C.) at the time of point (B) is changed to the room temperature (21.2 ° C.) while the control by the point (B) is being performed, the point (C). Point (D). Control is performed based on the point (E), and then the target room temperature (2

Although the present invention exemplifies an air conditioner as an air conditioner and an electric carpet as a heating device, the heating device is a petroleum hot air heater (fan heater) by convective heat.
Alternatively, an electric stove using electric radiation or electric kotatsu may be used. Further, the environmental temperature control means does not necessarily have to heat only the floor surface and may be any one that controls the temperature near the floor surface, and the point of the comfortable temperature curve is based on the room temperature of the air conditioner as in the embodiment. Instead of determining the floor surface temperature of the electric carpet, the room temperature of the air conditioner may be determined based on the floor surface temperature of the electric carpet. In addition, an automatic switch was installed on the remote control, but it was an air conditioner. It may be provided on the electric carpet.

[0040]

As described above, according to the present invention, a warming person in an indoor living space in which an air conditioner and a heating device are installed can comfortably set a preset comfortable temperature during the combined operation of the air conditioner and the heating device. Since environmental temperature control means for controlling the room temperature by the air conditioner and the temperature by the heating device based on the curve in a correlated manner is provided, even if the room temperature by the air conditioner or the temperature by the heating device is changed, it is possible to heat in a comfortable living space. it can. In particular, since the automatic temperature setting means selects and controls the energy point based on the comfortable temperature curve and the total energy consumption of the heating device and the heating device, the heating is economical and comfortable.

In addition, when the automatic temperature setting means is operated, since there is a slow control operation mode in which control is performed along each point of the comfortable temperature curve and control is shifted to the energy point, a rapid temperature change occurs. It is possible to shift to the energy point in a state in which is not generated and in a comfortable state.
