[0015]

According to the structure of the skeleton heat storage type air conditioning system according to the first aspect of the present invention, the skeleton heat storage is performed for each of the plurality of air-conditioned zones, and the air-conditioning load is measured for each of the air-conditioned zones. By determining whether or not is measured, it is determined whether or not the amount of heat stored in the skeleton of the previous day is sufficient, and the amount of heat stored in the skeleton is determined based on the determination result. In other words, when the air-conditioning load was measured, the measured amount of air-conditioning load was insufficient for the previous day's skeleton heat storage. I do. When the air conditioning load was not measured, the amount of heat stored in the skeleton was sufficient for the previous day, so it was assumed that there was a surplus in the amount of heat stored in the skeleton. Perform heat storage.

Further, according to the structure of the skeleton heat storage type air conditioning system according to the second aspect of the present invention, the shortage of the skeleton heat storage is supplied to the heat exchanger by forced circulation accompanying the operation of the compressor. In the case where the air conditioning load is compensated, the air conditioning load corresponding to the shortage is measured by measuring the operation time of the compressor.

Further, according to the structure of the skeleton heat storage type air conditioning system of the invention according to claim 3, the shortage of the skeleton heat storage amount is transferred to the heat exchanger by natural circulation flow accompanying the opening operation of the on-off valve. When supplying and supplementing, the air conditioning load corresponding to the shortage is measured by measuring the opening time of the on-off valve.

Further, according to the structure of the skeleton heat storage type air conditioning system of the invention according to claim 4, the shortage of the skeleton heat storage is exchanged with the refrigerant by natural circulation flow accompanying the adjustment of the opening of the flow control valve. In the case where the air supply is supplied to the air conditioner, for example, the opening degree detected every three minutes is integrated. Measure the air conditioning load.

Further, according to the structure of the skeleton heat storage type air conditioning system according to the fifth aspect of the present invention, the skeleton heat storage is performed for each of the plurality of air-conditioned zones, and the heat is actually stored for each of the air-conditioned zones within the normal air conditioning time. By measuring the actual air-conditioning load of the day required and comparing the actual air-conditioning load of the day with the actual air-conditioning load of the previous day, it is determined whether or not there is an excess amount of heat stored in the frame. Determine the amount of heat stored in the building. That is, when the actual air-conditioning load of the day is lower than the actual air-conditioning load of the previous day, it is considered that there is a surplus in the heat storage amount of the frame of the previous day because the amount of heat stored in the frame of the previous day is sufficient. The frame heat storage is performed by subtracting the air-conditioning load as the surplus frame heat storage amount and subtracting the surplus frame heat storage amount from the frame heat storage amount corresponding to the actual air-conditioning load of the day as a necessary frame heat storage amount. When the actual air-conditioning load of the day is higher than the actual air-conditioning load of the previous day, the heat storage of the frame corresponding to the actual air-conditioning load of the day is performed as the necessary heat storage of the frame because the heat storage of the frame of the previous day was insufficient.

Further, according to the structure of the air conditioner of the present invention, the air conditioner is constructed by radiating heat of the heat stored in the frame, and additional air conditioning is performed by a chase operation when the heat stored in the frame is insufficient. Even in the case of, the blower of the indoor air conditioner is in the driving state, and even when the blower is in the driving state, for example, the temperature of the air blown out from the indoor air conditioner and the When the difference from the return air temperature is within a predetermined temperature range, such as ± 0.5 ° C, when the absolute value of the above-mentioned temperature difference exceeds the predetermined value, considering that the operation is performed with no air conditioning load applied. Then, the air conditioning load is obtained based on the set air volume, the temperature difference, the time, and the specific heat of the blower, and the actual air conditioning load is accurately obtained by integrating the air conditioning load within a normal air conditioning time to calculate the actual air conditioning load. .

Further, according to the structure of the air conditioner system of the heat storage type according to the seventh aspect of the present invention, for example, when the air conditioner is sunny, cloudy,
Focusing on weather conditions such as rain and temperature, comparing the weather condition of the day with the expected weather condition of the next day, when it is expected that the temperature will be lower on the next day than on the day, in the case of cooling If so, the correction coefficient is obtained by reducing the required heat storage amount of the frame. In addition, taking into account the influence of the weather conditions of each zone to be air-conditioned, such as the presence or absence of windows and whether facing north or south, the required amount of heat stored in the building calculated based on the air-conditioning load is corrected. The skeleton heat is stored so that the required required amount of heat storage can be obtained.

According to the construction of the air conditioner system of the present invention, for example, in a room with windows, the cooling load becomes high on a sunny day due to a high degree of insolation on a sunny day. Paying attention to the fact that the degree of solar radiation has a large effect on the required amount of heat stored in the frame, as in the case where the load is low and the cooling load and heating load tend to be small on cloudy days. Thus, the required heat storage amount of the skeleton calculated based on the air conditioning load is corrected, and the skeleton heat storage is performed in each of the air-conditioned zones so that the corrected required heat storage of the skeleton is obtained.

First to sixth rooms R1, R2, R3, R
As shown in the block diagram of FIG. 4, a microcomputer 33 is provided in each of the R4, R5 and R6. The input means 34b is connected to the cooling opening sensor 31 and the heating opening sensor 32. Further, the microcomputer 33 causes the microcomputer 33 to perform a predetermined operation in the cooling operation mode or the heating operation mode during the normal operation time from 8:00 am to 8:00 pm, and outputs a start signal at 10:00 pm or the like. And the ice making machine 6 and the blower fan 17 are connected.

The cooling opening sensor 31 and the heating opening sensor 32 are connected to a pulse oscillator 36 which oscillates a pulse signal at predetermined time intervals, for example, every three minutes. The detected opening degree is output from the opening degree sensor 31 and the opening degree sensor 32 for heating to the microcomputer 33.

The microcomputer 31 includes an air-conditioning load measuring unit 37, a required heat storage amount calculating unit 38, a correction coefficient calculating unit 39, a correcting unit 40, and a heat storage control unit 41.

In the air-conditioning load measuring means 37, during the normal operation time set by the timer 35 (for example, from 8:00 am to 8:00 pm), the cooling opening sensor 31 or the heating opening sensor 32 is used. The opening degree detected at each set time is integrated, and the integrated opening degree, that is, the air-conditioning load corresponding to the shortage in the skeleton heat storage described later is measured by the amount of refrigerant actually flowing in for air conditioning. Has become.

More specifically, as shown in the graph of the relationship between the opening degree (%) and the time in FIG. 5, the opening degree detected at every set time such as 3 minutes is input, and the opening degree is calculated as follows. The opening is integrated assuming that the opening is continued until after the set time (3 minutes) after the opening is input.

On the day's weather condition input means 34a and the predicted weather condition input means 34b, the weather condition is set in advance according to each of the cooling operation mode and the heating operation mode.
The degree of insolation is numerically set in accordance with “sunny”, “cloudy”, “rain”, and “snow”. For example, at 7:00 pm, the manager checks the weather condition on the day and the expected weather condition (for the weather forecast). It is fine, cloudy)
By pressing a button such as "rain" or "snow", a digitized weather condition signal and a predicted weather condition signal are output. The input of the weather condition on the day and the predicted weather condition may be performed, for example, through a telephone, or it may be configured to automatically input by taking in the sound of a weather forecast.

As an example, in the cooling operation mode, 1.3 in "clear", 1.0 in "cloudy", and 0. 0 in "rain".
9 are output. There is no case of "snow". on the other hand,
In the heating operation mode, 0.9 is output for "sunny", 1.0 for "cloudy", 1.1 for "rain", and 1.3 for "snow". It should be noted that a plurality of buttons are pressed in the case of "sunny and cloudy" or "cloudy and sometimes rainy". Accordingly, in the cooling operation mode, the one with a higher degree of solar radiation is selected, and in the heating operation mode, the one with a higher degree of solar radiation is selected. That is, when the buttons “clear” and “cloudy” are pressed in “clear after cloudy”, “clear” is selected in the cooling operation mode, and “cloudy” is selected in the heating operation mode. In this way, the configuration is such that shortage of the body heat storage can be avoided as much as possible.

The correction coefficient calculating means 39 compares the weather condition signal of the day and the expected weather condition signal quantified as described above, converts the weather condition signal of the current day into a denominator and calculates the predicted weather condition signal by a division method. A correction coefficient is calculated as a numerator. That is, if the expected weather on the day and the next day is the same, “1” is calculated as the correction coefficient,
If the expected weather of the next day is "cloudy" with respect to "sunny" of the day, "1 / 1.3 (about 0.77)" is calculated in the cooling operation mode, while "1 / 0.9 (about 1.11)" is calculated in the heating operation mode. ) "Is calculated.

In the correcting means 40, the first to sixth rooms R1, R2, R3, R4, R5, R6
Corresponding to each, the degree of influence of the weather condition in each of the cooling operation mode and the heating operation mode is numerically set as a percentage in advance, and the percentage is multiplied by the correction coefficient input from the correction coefficient calculation unit 39. The correction value signal is calculated, and the correction value signal is output to the required skeleton heat storage amount calculating means 38.

An example in the case of the cooling operation mode is as follows. In the first room R1 having two windows, 120%, and in the second to fourth rooms R2, R3, R4 having one window, 100%. Then, in the fifth and sixth rooms R5 and R6 without windows, the ratio is set to 80%. In the case of the heating operation mode, contrary to the case of the cooling operation mode,
80% in the first room R1 having two windows, and 100% in the second to fourth rooms R2, R3 and R4 having one window.
% And the fifth and sixth rooms R5 without windows
In R6, it becomes 120%. As the degree of influence by the weather condition according to each air-conditioned zone, northward or southward may be further taken into account.

The required skeleton heat storage amount calculating means 38 stores the required skeleton heat storage amount calculated the day before as the skeleton heat storage amount of the previous day, and when the air conditioning load is input from the air conditioning load measuring means 37, the air conditioning load is calculated. Calculate the required skeleton heat storage amount by adding the derived skeleton heat storage amount to the skeleton heat storage amount of the previous day to the derived skeleton heat storage amount, and further, from the correction means 40 to the calculated required skeleton heat storage amount. Correction is made in accordance with the correction value signal to calculate the final required heat storage amount of the skeleton.

On the other hand, when no air conditioning load is input from the air conditioning load measuring means 37 during the normal operation time set by the timer 35 (for example, from 8:00 am to 8:00 pm), Is not measured, it is considered that there is a surplus in the skeleton heat storage amount because the previous day's skeleton heat storage amount is sufficient.
The required amount of heat stored in the skeleton is obtained by subtracting a predetermined amount from the amount of heat stored in the previous day, and the calculated required amount of heat is added to the calculated required amount of heat according to the correction value signal from the correction means 40. Is calculated.

The heat storage control means 41 calculates the drive time of the ice making machine 6 and the blower fan 17 based on the required heat storage amount of the frame calculated by the required heat storage amount calculation means 38, and outputs a drive signal for the calculated drive time. Output to the ice making machine 6 and the blower fan 1 by switching the damper 21 to the heat storage operation state.
7 is driven to store the required amount of heat stored in the skeleton.

Next, the control operation of the microcomputer 33 will be described in detail with reference to the flowchart of FIG.

As shown in the flowchart of FIG. 6, first, it is determined whether or not the cooling operation is performed based on the operation state of the operation switch (not shown) (S1). If it is determined that the cooling operation is performed, the process proceeds to step S2. , The day's weather condition input means 34
a, the predicted weather condition input means 34b and the correction means 40 are each set to the cooling operation mode, and the detected opening degree at predetermined time intervals is output only from the cooling opening degree sensor 31 to the air conditioning load measuring means 37.

If it is not the cooling operation in step S1, it is determined that the operation is heating operation, and the process shifts to step S3 to set each of the weather condition input means 34a, predicted weather condition input means 34b and correction means 40 on the day to the heating operation mode. , For a predetermined time (3
The detected opening degree for each minute is output to the air conditioning load measuring means 37.

The timer 35 outputs an operation signal to the air-conditioning load measuring means 37 and the necessary frame heat storage amount calculating means 38 during a normal operation time, regardless of whether the timer is set to the cooling operation mode or the heating operation mode. After the end of the normal operation time, the heat storage control means 41 is caused to output the final required frame heat storage amount.

After step S2 or step S3, the process proceeds to step S4 to input the heat storage amount QA of the previous day, and then input the opening of the cooling opening sensor 31 or the heating opening sensor 32. (S5), the air conditioning load is integrated (S6).

Thereafter, the flow shifts to step S7, where
It is determined whether or not the time has elapsed. Until 8:00 pm, the process proceeds to step S8 and the flag is set (F =
1) It is determined whether or not.

Thereafter, at a predetermined time such as 8:00 pm in the evening, for example, at 7:00 pm, the day-of-day weather condition obtained by the manager inputting the day-time weather condition input means 34a and the expected weather condition input means 34b. The signal and the predicted weather condition signal are input to the correction coefficient calculating means 39 (S9, S9).
10) Compute the correction coefficient by comparing the two signals (S1).
1).

Next, the calculated correction coefficient is multiplied by a percentage of the degree of influence of the weather condition set in advance for each room to calculate a correction value signal (S12), and the flow shifts to step S13. Until the correction value signal is calculated, the process proceeds from step S9 to step S13 without any change to step S5. After the correction value signal is calculated, step S1 is performed.
Then, the process proceeds to step S5, where a flag is set (F = 0 → 1), and the process proceeds to step S5.

After the above-described correction value signal is calculated, the process proceeds from step S5 to step S8 until 8:00 pm has elapsed, and the detected opening is input to integrate the air conditioning load. After 8:00 pm set by the timer 35 has elapsed, the process proceeds from step S7 to step S15, where the flag is lowered (F = 1 →
From step 0), the process proceeds to step S16, and it is determined whether or not an air conditioning load has been input, that is, whether or not an air conditioning load has been input from the air conditioning load measuring means 37 to the necessary frame heat storage amount calculating means.

When an air conditioning load is input, that is,
The heat storage amount QA of the previous day was insufficient to cover cooling or heating on the day because the cooling flow control valve 28 or the heating flow control valve 29 was opened, and the natural circulation of the refrigerant caused the ice heat storage tank 7 or the hot water tank to open. When it is determined that the stored cold or warm heat has been consumed, the process proceeds to step S17, in which the frame heat storage amount QB corresponding to the air-conditioning load (step S6) integrated by the air-conditioning load measuring means 37 is derived.
The sum of the heat storage amount QB of the previous day and the heat storage amount QA of the previous day is calculated as the required heat storage amount QC (QA + QB →
QC).

If there is no input of the air-conditioning load in step S16, that is, if the air-conditioning load is not measured and it is determined that the heat storage amount QA of the previous day is sufficient and there is a surplus in the heat storage amount of the frame, the process proceeds to step S19. It is necessary to reduce the body heat storage QA on the previous day by 5%
(QA × 0.95 → QC).

After calculating the required frame heat storage amount QC, the required frame heat storage amount QC is replaced with the frame heat storage amount QA of the previous day (S20), and the necessary frame heat storage amount QC is corrected by the correction means 4.
Correction is made in accordance with the correction value signal from 0 to calculate the final required body heat storage Q (S21).

Next, the process proceeds to step S22, in which the ice making machine 6 necessary to obtain the final required frame heat storage amount Q is prepared.
And the drive time T of the blower fan 17 is calculated, a drive signal is output for the calculated drive time T, the damper 21 is switched to the heat storage state, and the ice making machine 6 and the blower fan 17 are driven. The required amount of heat is stored in the body.

According to the above configuration, it is possible to perform appropriate heat storage of the frames R1 to R6 according to the expected weather of the next day, and it is not necessary to store the heat more than necessary, thereby reducing the running cost. It became so.

Next, the first to the first obtained according to the change of the weather.
A calculation example of the final required body heat storage amount Q in the sixth rooms R1, R2, R3, R4, R5, and R6 will be described. If the required skeleton heat storage amount QC based on the air conditioning load is insufficient for the previous day, the required skeleton heat storage amount QC = the previous day skeleton heat storage amount QA +
If the body heat storage QB on the day is sufficient, the required body heat storage QC = the previous day's body heat storage QA x 0.95, but in this description any case may be used, and the necessary body heat storage QC is corrected. Is shown.
