The temperature detecting device 8 is detected by a remote control temperature detecting means 1 provided in a control device of an air conditioning system such as a remote control, a heat capacity setting means 2 for setting a heat capacity of a mounting position of a remote control or the like, and a temperature detected by the remote control temperature detecting means 1. The room temperature estimating means 3 for estimating the indoor temperature based on the obtained temperature data and the heat capacity set by the heat capacity setting means 2, and the temperature data detected by the remote control temperature detecting means 1 and the estimated room estimated by the indoor temperature estimating means 3. The output of the indoor temperature estimating unit 3 is input to an air conditioner control unit 5 that controls the operation of the entire air conditioning system.

The air conditioner controller 5 outputs a control signal to the blower fan 6 of the indoor unit and the compressor 7 of the outdoor unit based on the indoor temperature data estimated by the indoor temperature estimating means 3. Remote control temperature detection means 1
Detects the temperature in the room near the remote controller to which the remote controller is attached by using a temperature sensor provided in the remote controller.

A method of setting the heat capacity in the heat capacity setting means 2 for setting the heat capacity of the place where the remote control incorporating the remote control temperature detecting means 1 is attached is described.
This will be described with reference to the flowchart shown in FIG. Step 51
Then, the mode is shifted from the mode in which the air-conditioning system is normally operated by the remote controller to the heat capacity setting mode in step 52 by a combined (combined) operation of switches, for example, by simultaneously pressing the "room temperature adjustment up / down switch". Here, the switch of one remote control is used for two modes, the mode of the function different from the normal operation mode (heat capacity setting mode). The data can be corrected, the room temperature can be estimated more accurately, and the cost can be reduced. In step 52, the magnitude of the heat capacity at the place where the remote control is attached is selected, for example, by operating the "wind speed adjustment switch", the magnitude C of the heat capacity selected on the liquid crystal display unit of the remote control. FIG. 3 is a list of coefficients determined by the heat capacity. As shown in FIG. 3, it is assumed that three stages can be selected, and as an example of the three stages, C1>C2> C
Assuming 3, C1 is a concrete wall (no heat insulation), C2
Can be classified as a concrete wall (with heat insulation), and C3 can be classified as a gypsum wall. In step 53, the magnitude C of the heat capacity selected by the combined operation of the switches used in step 51 is determined (set). Here, after selecting the magnitude of the heat capacity in step 52, the determination in step 53 is performed in order to prevent an erroneous operation in which the heat capacity is determined by accidentally touching a switch of the remote controller. Therefore, step 53 may not be necessary. In step 54, the allowable change rate α which is a coefficient for determining the magnitude of the temperature change, the transient maximum allowable temperature difference β which determines the temperature range of the estimated temperature during the temperature change, and no temperature change has occurred. The steady-state maximum allowable temperature difference γ that determines the temperature range of the estimated temperature at the time is shown in FIG.
The one corresponding to C2 and C3 is determined, the heat capacity setting mode is released, and the operation mode is returned to the normal operation mode.

Next, the indoor temperature estimating means 3 receives the temperature data from the remote control temperature detecting means 1, the heat capacity data from the heat capacity setting means 2, and the past temperature data from the remote control temperature detecting means 1 stored in the storage means 4. Using the past estimated indoor temperature data from the indoor temperature estimating means 3,
Estimate the current room temperature.

The processing operation of the indoor temperature estimating means 3 will be described.
This will be described with reference to the flowchart shown in FIG. In this state,
In step 101, the temperature data value Trc (n) of the remote controller temperature detecting means 1 after n cycles is detected, and
In step 2, a difference ΔTrc (n) between Trc (n) and the previously detected temperature data Trc (n−1) is calculated to compare the fluctuation of Trc (n), and the difference ΔTrc (n) is compared with the allowable change rate α. I do. As shown in FIG. 3, the allowable change rate α changes depending on the heat capacity C.
Is larger, the smaller the value of C, the larger the value of C. From the result of this comparison, it is determined whether the temperature change in the room is a steady state or a transient state. ΔTrc (n)
≦ α, that is, in the steady state, the routine proceeds to step 103, where ΔT
If rc (n)> α, that is, in the transient state, the process proceeds to step 104.

In step 104, the modified change rate ΔT'rc
(n) is calculated by multiplying ΔTrc (n) calculated in step 102 by a constant determined in accordance with the heat capacity C, and calculating the temperature data from the temperature detecting means 1 in the transient state of the change in room temperature. The sensitivity of the sensor is increased by increasing the rate of change, and the estimated remote control temperature T''rc (n) is calculated by adding or subtracting the corrected rate of change ΔT'rc (n) and the sensor temperature Trc (n). I do.

In step 105, the difference between the estimated remote controller temperature T ″ rc (n) calculated in step 104 and the temperature data Trc (n) detected by the remote controller temperature detecting means 1 is calculated, and the maximum during the transition is calculated. Comparison with the allowable temperature difference β,
It is determined whether T ″ rc (n) is estimated within an allowable range. The transient maximum allowable temperature difference β changes depending on the heat capacity C. The larger the C, the larger the β, and the smaller the C, the smaller the β. At this time, | T ″ rc (n) −Trc (n) |
If it is larger, the process proceeds to step 106;

In step 106, since T ″ rc (n) estimated in step 104 does not converge within the allowable range determined by the heat capacity C, the remote controller temperature detecting means 1
Corrected or obtained by adding or subtracting the transient maximum allowable temperature difference β to the temperature data Trc (n).
Then, the process proceeds to step 110.

In step 107, since T ″ rc (n) estimated in step 104 converges within an allowable range determined by the heat capacity C, T ″ rc (n) is corrected to the corrected remote control temperature TCrc ( The process proceeds to step 110 as n).

In step 103, the corrected remote controller temperature TCrc (n-1) calculated by the previous indoor temperature estimating means 3 is calculated.
Temperature data Trc detected by remote controller temperature detecting means 1
The difference from (n) is calculated and compared with the maximum allowable steady-state temperature difference γ to determine whether TCrc (n−1) has been estimated within an allowable range. Constant maximum allowable temperature difference γ changes depending on heat capacity C, and γ increases as C increases,
As C becomes smaller, γ also becomes smaller. If the result of the comparison is larger than γ, the process proceeds to step 108;

In step 108, the room temperature estimating means 3
Since the previous corrected remote control temperature TCrc (n-1) calculated in step (1) does not converge to the allowable range in the steady state determined by the heat capacity C, the temperature data Trc (n) detected by the remote control temperature detecting means 1 An averaging calculation is performed to asymptotically calculate a corrected remote control temperature TCrc (n), and step 1
Proceed to 10.

In step 109, the temperature data Trc (n) detected by the remote controller temperature detecting means 1 is used as the corrected remote controller temperature TCrc (n), and the process proceeds to step 110.

At step 110, the corrected remote controller temperature TCrc (n) output from step 106, step 107, step 108 or step 109 is output to the air conditioner controller 5 of the air conditioning system as the estimated indoor temperature T (n). Then, after a certain period, return to step 101,
Perform temperature detection.

The variables used in the indoor temperature estimating means 3 are as follows:
It is assumed that the information is temporarily stored in the storage unit 4 and is appropriately read when the indoor temperature is estimated by the indoor temperature estimation unit 3.

As described above, in a control device for inputting the operating state of the air conditioning system to the temperature detection device of the air conditioning system, for example, in a remote controller, it is possible to set the magnitude of the heat capacity at the position (wall surface) where the remote controller or the like is mounted. By providing a heat capacity setting means capable of realizing an air-conditioned space in consideration of the heat capacity of the wall surface, it is possible to estimate the temperature at the center of the room from temperature data detected by temperature detection means provided on a remote controller or the like. This becomes possible, and particularly when the fluctuation of the room temperature is large, the fluctuation of the measured temperature is amplified to estimate the room temperature, so that the followability of the estimated temperature to the room temperature can be improved. The estimated temperature is used for comparison with the set temperature in the air conditioner control unit, and by driving the blower fan and the compressor according to a predetermined control law, the indoor temperature can be easily set to the set temperature.

It is input to the air conditioner control unit 15 that performs operation control.

The air conditioner control unit 15 is provided with an indoor temperature estimating unit 13.
Based on the estimated indoor temperature data, a control signal is output to the blower fan 16 of the indoor unit, the compressor 17 of the outdoor unit, and the like. The remote controller temperature detecting means 11 detects the temperature in the room near the remote controller to which the remote controller is attached by using a temperature sensor provided in the remote controller.

FIG. 9 shows the remote controller temperature detecting means 11.
And a model diagram (indoor diagram) of a room where the temperature is measured by the indoor temperature detecting means 18. In the figure, C is the heat capacity of the wall, 11 is remote control temperature detecting means provided on the remote control and its detected temperature is Trc, and 18 is the indoor unit side temperature detecting means provided in the indoor unit and its detected temperature is Tic.
And the room temperature was Troom. Now, the indoor unit and the remote controller are located apart from each other, and in the first embodiment, the temperature detector is only one of the remote controller temperature detectors 11.
In the present embodiment, two remote control temperature detecting means 11 and indoor unit temperature detecting means 18 are used, and a distance between them is set so that they do not overlap in the vertical direction as much as possible, so that the temperature of the entire room can be detected. I did it.

A method of setting the heat capacity in the heat capacity setting means 12 for setting the heat capacity of the place where the remote control incorporating the remote control temperature detecting means 1 is mounted will be described with reference to the flowchart shown in FIG. In step 61, the mode is shifted from the mode in which the air conditioning system is normally operated by the remote controller to the heat capacity setting mode by the combined (combined) operation of the switches, for example, by simultaneously pressing the "room temperature adjustment up / down switch". Here, the switch of one remote controller is used in two modes, a normal operation mode and a mode having a different function.

In step 62, the magnitude of the heat capacity at the place where the remote control is mounted is selected, for example, by operating the "wind speed adjustment switch" to select the magnitude C of the heat capacity selected on the liquid crystal display section of the remote control. FIG. 7 is a list of coefficients determined by the heat capacity. As shown in the figure, it is assumed that, for example, three stages can be selected. As an example of the three stages, C1 is a concrete wall (without heat insulation) and C2 is a concrete wall (with heat insulation). ) And C3 can be classified into plasterboard walls and the like.

In step 63, the magnitude C of the heat capacity selected by the combined operation of the switches used in step 61 is determined (set). Here, the reason for determining the step 63 after selecting the magnitude of the heat capacity in the step 62 is to prevent a malfunction such that the heat capacity is determined by accidentally touching the switch of the remote controller. Therefore, step 63 may not be necessary. Step 6

The maximum allowable temperature difference γ at steady state for determining the temperature range of the estimated temperature and the weight coefficient ε of the remote controller-indoor unit corresponding to each of the heat capacities C1, C2 and C3 are determined according to FIG.
Release the heat capacity setting mode and return to the normal operation mode.

Next, the room temperature estimating means 13 receives the temperature data from the remote control temperature detecting means 11 and the heat capacity setting means 12
The current indoor temperature is estimated using the heat capacity data from the remote controller, the past temperature data from the remote controller temperature detecting means 11 stored in the storage means 14, and the past estimated indoor temperature data from the indoor temperature estimating means 13. .

The processing operation of the indoor temperature estimating means 3 will be described.
This will be described with reference to the flowchart shown in FIG. In this state,
At step 121, the temperature data value Trc (n) of the remote controller temperature detecting means 11 at time t is detected, and
In step 2, a difference ΔTrc (n) between Trc (n) and the previously detected temperature data Trc (n−1) is calculated and compared with the allowable change rate α in order to compare the fluctuation of Trc (n). As shown in FIG. 7, the allowable change rate α changes depending on the heat capacity C. As C increases, α decreases, and as C decreases, α increases. From the result of this comparison, it is determined whether the temperature change in the room is a steady state or a transient state. ΔTrc (n) ≦ α
In other words, if it is in a steady state, the process proceeds to step 123,
If (n)> α, that is, in the transient state, the process proceeds to step 124.

In step 124, the modified change rate ΔT'rc
(n) is calculated by multiplying ΔTrc (n) calculated in step 102 by a constant determined according to the heat capacity C, and in the transient state of the change in room temperature, the temperature data from the temperature detecting means 11 is calculated. The sensitivity of the sensor is increased by increasing the rate of change, and the estimated remote control temperature T''rc (n) is calculated by adding or subtracting the corrected rate of change ΔT'rc (n) and the sensor temperature Trc (n). I do.

In step 125, the difference between the estimated remote control temperature T ″ rc (n) calculated in step 124 and the temperature data Trc (n) detected by the remote control temperature detecting means 11 is calculated, and the maximum during the transition is calculated. Comparison with the allowable temperature difference β,
It is determined whether T ″ rc (n) is estimated within an allowable range. The transient maximum allowable temperature difference β changes depending on the heat capacity C. The larger the C, the larger the β, and the smaller the C, the smaller the β. At this time, | T ″ rc (n) −Trc (n) |
If it is larger, proceed to step 126;

At step 126, since T ″ rc (n) estimated at step 124 does not converge within the allowable range determined by the heat capacity C, the remote controller temperature detecting means 1
The maximum allowable temperature difference β during the transition is added to the temperature data Trc (n) of FIG.
Remote control temperature TCrc is corrected by adding or subtracting
The process proceeds to step 131 as (n).

In step 127, since T ″ rc (n) estimated in step 124 converges within the allowable range determined by the heat capacity C, T ″ rc (n) calculated in step 124 Is set as the corrected remote control temperature TCrc (n), and the routine proceeds to step 131.

In step 123, the corrected remote controller temperature TCrc (n-1) calculated by the previous indoor temperature estimating means 13
Is calculated with the temperature data Trc (n) detected by the remote controller temperature detecting means 11 and compared with the maximum allowable temperature difference γ at the steady state, so that TCrc (n-1) is within the allowable range. It is determined whether or not it has been estimated. The constant maximum allowable temperature difference γ changes depending on the heat capacity C. As C increases, γ increases, and as C decreases, γ decreases. The result of the comparison is γ
If it is larger, the process proceeds to step 128, and if it becomes smaller, the process proceeds to step 129.

In step 128, the indoor temperature estimating means 1
Since the previous corrected remote control temperature TCrc (n-1) calculated in step 3 does not converge to the allowable range in the steady state determined by the heat capacity C, the temperature data Trc (n) detected by the remote control temperature detecting means 11 Is calculated in order to asymptotically approach, and the corrected remote control temperature TCrc (n) is calculated.

In step 129, the temperature data Trc (n) detected by the remote controller temperature detecting means 11 is used as the corrected remote controller temperature TCrc (n), and the process proceeds to step 131.

In step 130, the indoor unit temperature detecting means 18 detects the indoor unit temperature Tic (n). In step 131, the corrected remote controller temperature TCrc (n) and the indoor unit temperature Tic (n) output from step 126, step 127, step 128, or step 129 are averaged using the weighting coefficient ε, and the estimated indoor temperature T (n ). Here, the weighting coefficient ε is, for example, the indoor temperature detecting means 1
8 is mounted at a position higher than normal, such as 3 to 4 m, the weight of the room temperature data from the room temperature detection unit 18 is made smaller than the room temperature data from the remote control temperature detection unit 11, and the room temperature Average. The weighting of the room temperature data from the room temperature detecting means 18 and the room temperature data from the remote control temperature detecting means 11 according to different forms of the indoor unit, for example, floor placement, wall hanging, ceiling embedding, etc. Can be adjusted. If the heat capacity is large, the remote control temperature detecting means 11
Reduce the weight of the data.

The estimated room temperature T (n) estimated in step 131 is output to the air conditioner control unit 5 of the air conditioning system.
After a predetermined period, the process returns to step 121 to perform temperature detection.

The variables used by the indoor temperature estimating means 13 are temporarily stored by the storage means 14 and are read out appropriately when the indoor temperature estimating means 13 estimates the indoor temperature.

As described above, the temperature data obtained from the temperature detecting means built in the conventional control device can be corrected and estimated by the indoor temperature estimating means according to the magnitude of the heat capacity set by the heat capacity setting means. It is possible to realize a temperature detection device of an air-conditioning system capable of reducing the influence on the temperature detection by the mounting position of the control device and enabling more accurate estimation of the room temperature. The installation position of the remote control temperature detection means (11) can not only estimate the room temperature in consideration of the heat capacity, but also detect the temperature outside the air conditioner (outside of the airflow), In (2), the provision of the remote control temperature detecting means (11) on the wall opposite to the indoor unit enables the indoor temperature to be more accurately estimated.

The temperature detecting means attached to the indoor unit is also used for estimating the indoor temperature, and the temperature data obtained from the indoor temperature estimating means and the temperature data from the temperature detecting means built in the indoor unit are averaged. This makes it possible to reduce the variation in the detected temperature due to the difference in the mounting position of the control device and the indoor unit, and to make corrections in consideration of the height of the installation location of each temperature detection means. By using the converted temperature for comparison with the set temperature in the air conditioner control unit and driving the blower fan or the compressor according to a predetermined control law, the indoor temperature can be easily set to the set temperature. A temperature detection device for an air conditioning system that can accurately estimate the room temperature can be realized.
