2. Description of the Related Art For example, in an air conditioning system for a medium-scale building, an air conditioning controller is installed in the air conditioned space, that is, the inner wall of each room. This air-conditioning control controller can remotely control an indoor unit in each room, and easily realizes centralized monitoring and control in an air-conditioning system including each indoor unit.

FIG. 4 shows an example of how the conventional air conditioning control controller is attached. This air-conditioning control controller includes a controller body 1 (see FIG. 5) embedded in the inner wall 100 of the room where the air-conditioning control is to be performed, and an operation / display panel 2 attached to the controller body 1. On the operation / display panel 2, as shown in FIG.
An operation unit 3 for performing various inputs, a display unit 4 including a liquid crystal display device for displaying temperature, etc. are provided. Since the controller body 1 is embedded in the inner wall 100 as described above, the operation / display panel 2 is installed so as to be substantially flush with the inner wall 100.

Further, the controller body 1 includes a computing unit (not shown) composed of a plurality of semiconductor elements and the like. However, as shown in FIG. A room temperature sensor 5 for detection is attached. The room temperature sensor 5 is composed of, for example, a thermocouple, and is arranged corresponding to the sensor installation portion 6 of the operation / display panel 2. Since the room temperature sensor 5 is extremely small and easily damaged, the room temperature sensor 5 is installed near the controller body 1 as described above, and the sensor installation section 6
At, it is covered with a lid or the like having slits.

The room temperature detected by the room temperature sensor 5 can be displayed on the display section 4 of the operation / display panel 2, so that the operator can adjust it to a desired room temperature while referring to the displayed temperature. In order to do so, an input operation is performed on the operation unit 3. For example, if you want to raise the room temperature,
The operation button 3a for "raise" is operated. The controller body 1 controls an indoor unit (not shown) based on the set temperature (set temperature), thereby performing air conditioning control.

[0006]

However, since the conventional air-conditioning control controller is attached to the inner wall 100 as described above, the room temperature sensor 5 is attached to the inner wall 100 from the inner wall 100.
There is a problem that the temperature detected by the room temperature sensor 5 is greatly affected by the heat conduction to the room temperature, and the room temperature cannot be accurately measured. Further, the controller main body 1 itself generates heat due to the operation of the controller, but in this case as well, there is a problem that the temperature detection accuracy of the room temperature sensor 5 is significantly affected by heat conduction from the controller main body 1 to the room temperature sensor 5. It was If the room temperature cannot be accurately detected in this way, the set temperature itself, which should be set based on this, cannot be accurately known, which makes it difficult to perform proper air conditioning control. It was

The present invention has been made in view of the above problems, and an object thereof is to provide a controller for air-conditioning control which can always detect a room temperature accurately and guarantee proper air-conditioning control.

Controller temperature detecting means, and a correcting means for correcting the output value of the room temperature detecting means based on the output value of the controller temperature detecting means, with reference to the degree of thermal influence by the controller main body obtained in advance. ing.

In this air conditioning controller, first,
The room temperature is detected by the room temperature detecting means. Further, temperature detecting means for measuring the temperature of the controller main body is additionally provided, and this temperature detecting means detects the temperature of the controller itself. The output value of the room temperature detecting means and the output value of the controller temperature detecting means are input to the controller body, and the correcting means calculates the thermal influence degree by the controller body at the temperature based on the output value of the controller temperature detecting means. The calculated value is used as a reference to correct the output value of the room temperature detecting means. Thereby, the accurate room temperature can be detected.

And means.

In this air-conditioning controller, the room temperature sensor basically detects the room temperature, but since the room temperature sensor is arranged in the vicinity of the controller body and the controller body itself is buried in the wall, these controller body and It is affected by heat conduction from the interior wall. Then, the output value of the room temperature sensor is input to the controller body.
On the other hand, the controller temperature sensor detects the temperature of the operating controller itself, and its output value is similarly input to the controller body.

Here, the degree of influence of the heat generation of the controller main body and the heat transfer to the room temperature sensor due to the wall temperature on the detected value is obtained in advance so that the controller main body of the controller main body detected at that time is detected. It is possible to detect how much the output value of the room temperature sensor at that time influences the temperature. In the arithmetic processing unit of the controller body, the output values of both the room temperature sensor and the controller temperature sensor are input, and these output values are calculated, that is, the output value of the room temperature sensor is affected by the output value of the controller temperature sensor. Degrees are added or subtracted. Therefore, the effects of heat generation of the controller body itself and the wall temperature on the room temperature sensor are compensated.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic configuration example of an air conditioning controller 10 according to an embodiment of the present invention. In the figure, 11 is a controller main body, 12 is an operation / display panel, 13 is an operation unit, 14 is a display unit, 15 is a room temperature sensor,
16 is a sensor installation part. The basic configuration of these components is similar to the conventional one (see FIGS. 4 and 5), and therefore detailed description thereof is omitted here.

The controller body 11 has a substrate 11a.
The calculation processing unit 17 is included in the calculation processing unit 17, and the detected temperature output value of the room temperature sensor 15 is input to the calculation processing unit 17.

In the present embodiment, especially the controller body 11
A controller temperature sensor 18 for measuring the temperature of the controller body 11 is provided on the substrate 11a. The controller temperature sensor 18 is composed of, for example, a thermocouple, and is arranged in proximity so that the temperature of the controller main body 11, particularly the substrate 11a thereof can be detected. The detected temperature output value of the controller temperature sensor 18 is input to the arithmetic processing unit 17.

FIG. 2 shows a configuration example of the arithmetic processing unit 17 in the air conditioning control controller 10 according to this embodiment. The CPU (Central Processing Unit) 19 is an RO via a bus.
It is connected to M (read only memory) 20, RAM (random access memory) 21, and the like. R
The OM 20 stores a correction program for correcting the room temperature. Further, the RAM 21 stores, as temperature data, the influence temperature of the heat generated by the controller body 11 itself and the temperature of the inner wall 100 on the detection value of the room temperature sensor 15. The affected temperature data can be obtained in advance for each temperature of the controller body 11, for example. The output values of the room temperature sensor 15 and the controller temperature sensor 18 are input to the CPU 19 via the input port 22, and the calculation result of the CPU 19 is output port 2.
3 to the indoor unit 24 or the like. CPU 19
Based on the output values of the room temperature sensor 15 and the controller temperature sensor 18, a predetermined correction calculation is executed according to the correction program stored in the ROM 20. The controller 10 is connected to the indoor unit 24, and the arithmetic processing unit 17
By performing the signal processing of, the room temperature up / down command and the like are transmitted to the indoor unit 24 based on the input operation of the operation unit 13.

Next, the operation of the air conditioning control controller 10 of this embodiment will be described with reference to the flow chart shown in FIG.
When the air conditioning control of the room to be controlled is started, the room temperature sensor 15 detects the room temperature of the room (step S100), and its output value T1 is input to the arithmetic processing section 17. On the other hand, the controller temperature sensor 18 detects the temperature of the operating controller body 11 itself (step S101), and its output value T2 is similarly input to the arithmetic processing section 17. The controller 10 generates heat due to its operation,
The temperature of the inner wall 100 is also affected by the temperature of the inner wall 100, so that the output value T1 of the room temperature sensor 15 is usually affected by the heat generation of the controller 10. That is,
The output value T1, which is the temperature detected by the room temperature sensor 15, generally tends to be higher than the actual room temperature T0 at that time.

In the case of the output value T2 of the controller temperature sensor 18, the arithmetic processing unit 17 obtains the influence temperature ΔT on the output value T1 of the room temperature sensor 15 due to the heat generation of the controller 10 and the wall temperature (step S1).
02). The CPU 19 then outputs the output value T1 of the room temperature sensor 15 according to the correction program stored in the ROM 20.
Then, the actual room temperature T0 is calculated from the influence temperature ΔT. For example, the output value T1 of the room temperature sensor 15 is the actual room temperature T0.
In this case, the actual room temperature T0 is calculated by subtracting the influence temperature ΔT from the output value T1 (step S103). The room temperature T0 thus obtained can be displayed on the display unit 14 from the CPU 19 through the output port 23, whereby the correct room temperature at that time can be known.

When the room temperature is adjusted, the operation button 13a for "increase" or "decrease" is operated to input the set temperature t (step S104). A signal from the operation of the operation button 13a is input to the CPU 19 through the input port 22 to set temperature t and room temperature T at that time.
It is determined whether it is higher or lower than 0 (step S105), and if there is a difference between the set temperature and the room temperature T0, the air conditioning control is executed. Furthermore, the adjustment temperature Δ which is the difference between these temperatures t and T0
t is calculated (step S106). For example, if the room temperature T0 at that time is desired to be higher, the operation button 13a for "raise" is pressed, whereby a drive signal is sent from the CPU 19 to the indoor unit 24 via the output port 23. In the indoor unit 24, the room temperature is set to the set temperature t,
It operates until the adjusted temperature Δt becomes zero (step S1).
07).

As described above, in this embodiment, the room temperature sensor 15 is used.
However, even when affected by heat conduction from the controller body 11 and the inner wall 100 of the chamber,
Of the room temperature sensor 15 and the controller temperature sensor 18 are input to the arithmetic processing unit 17, and a predetermined arithmetic operation is performed using these output values to detect an accurate room temperature. You can

By setting the room temperature and controlling the driving of the indoor unit 24 on the basis of the accurate room temperature obtained in this way, the heat generated by the controller 10 and the temperature of the inner wall 100 are not affected, and the temperature is always appropriate. Air conditioning control can be realized.

Further, especially at the start-up of the air conditioning control,
When the temperature difference between the room temperature and the inner wall 100 is large, or when the temperature reaches a steady state after a lapse of time and the temperature difference between the room temperature and the inner wall 100 becomes small, the room temperature is kept constant in both cases. can do.

The present invention has been described with reference to the examples.
The present invention is not limited to the above-mentioned embodiments, but various modifications can be made without departing from the scope of the invention. For example, a temperature sensor for detecting the temperature of the inner wall 100 may be provided at a proper position on the inner wall 100 where the controller 10 is installed, so that the influence of heat conduction from the inner wall 100 can be more surely eliminated. You can
