Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic test-operation device for air-conditioning equipment equipped with a plurality of heat terminals, and is particularly suitable as an automatic test-operation equipment for air-conditioning equipment equipped with heat terminals using hot water as a heat source.

[0002]

2. Description of the Related Art In recent years, central heating using a water heater has become widespread. First, the configuration of central heating using a water heater will be briefly described with reference to FIG. The central heating is composed of a large water heater 1 and five heat terminals 2, 3, 4, 5, 6 connected to it. Here, the water heater 1 includes a hot water tank 7, a pump 8, and a heat exchanger 10. The hot water tank 7 is connected to the water inlet of the pump 8 by piping, and the discharge port of the pump 8 is branched into two branches via the temperature detector 11. One of the two forks is connected to the low temperature hot water outlet 13.
The remaining one is connected to the hot water outlet 17 via the heat exchanger 10 and the temperature detector 15.

The hot water return port 18 of the water heater 1 has a temperature detector 2
It is connected to the hot water tank 7 through 0. Furthermore, inside the water heater 1, a bypass pipe 21 is provided between the hot water outlet 17 and the hot water return port 18 described above.

Of the five heat terminals, those numbered 2, 3, 4, and 6 are heat terminals for air conditioning, and include heat exchangers for hot water and refrigerators and fans for cooling. Is built in. On the other hand, the heat terminal 5 is mainly used for floor heating, and has only a heat exchanger for hot water.

The three air conditioning heat terminals 2, 3, 4
The floor heating thermal terminal 5 is connected to the low-temperature hot water outlet 13 of the water heater 1 via the thermal valves 23, 24, 25, and 26. The outlets of these heat terminals 2, 3, 4, 5 are collected by a collecting pipe 28 and connected to the hot water return port 18 of the water heater 1. Further, the air conditioning heat terminal 6 is
It is connected between the hot water outlet 17 and the collecting pipe 28 via a thermal valve 30.

Central heating includes a main controller 31, a sub-controller 32 of each thermal terminal,
It is controlled by 33, 34, 35 and 36. When the heat terminal 2 or the like is used for heating, the heat valve 23 or the like is opened to circulate hot water in the heat exchanger of the heat terminal,
When cooling is required, the refrigerator or fan built in each of the thermal terminals 2, 3, 4, 6 is started.

By the way, in the central heating, since the water heater 1 and the heat terminals 2, 3, 4, 5, 6 are arranged on different floors or rooms, respectively, complicated piping work is required between them. . Therefore, it is not uncommon for workers to make incorrect piping. Therefore, in central heating, a test run after piping work is essential. Therefore, the main controller 31 for central heating has a built-in automatic test operation device that automatically performs a test operation after piping work.

In the prior art automatic test operation device, the heating test operation and the cooling test operation are set as a set and performed for each heat terminal. Hereinafter, regarding the automatic test operation device of the prior art,
Control of the trial run and its display will be described with reference to the flowcharts of FIGS. 10 and 12. In the prior art automatic test operation device, when the automatic test operation is started, STEP 101
In step 102, one of the thermal terminals is selected in step 102. And STEP1
In 03, first, the trial run of heating is performed. When the heating test operation is completed, the process proceeds to STEP 104 to perform the cooling test operation. That is, in the conventional automatic test operation device, STEP10
The thermal terminal selected in 2 was first subjected to the heating test operation, and then the same thermal terminal was subjected to the cooling test operation.

When the air conditioning test run is completed, STEP1
Go to 05, if there is a thermal terminal for which trial operation has not ended, S
Return to TEP102. When the trial operation of all the thermal terminals is completed, the automatic trial operation process is completed.

The heating test operation of each thermal terminal 2 is performed by opening only the thermal valve 23 or the like to which these thermal terminals are connected. Then, the discharge temperature of the water heater detected by the temperature detector 15 and the temperature of the return hot water detected by the temperature detector 20 are compared, and if there is a certain difference between them,
Judge that the thermal terminal is functioning normally. In the cooling test operation, the refrigerator or fan of each thermal terminal is started, and when the sub-controller 32 detects a certain low temperature, it is determined that the thermal terminal is functioning normally.

In addition, in the prior art automatic test run system, as shown in FIG.
As shown in the flowchart of No. 2, when the automatic test operation is started, the clock display of the display device 45 (LED) immediately shows "0.
0H ”. The display of "00H" means that the automatic test operation is currently being performed. And "00
The display of "H" was not changed at all until the automatic trial run was switched off, regardless of the control of the automatic trial run shown in FIG.

[0012]

The automatic test-driving apparatus of the prior art is preferable because it can automatically perform troublesome test-driving. However, the prior art automatic test operation device has a problem that it takes a long time to perform the test operation, and has left a point to be improved. That is, in the control of the automatic test operation device of the related art, after the heating test operation is performed, the cooling test operation is always performed on the same thermal terminal. In other words, the prior art automatic test operation device continuously performs the heating and cooling test operations for one thermal terminal as a series of operations, and after both of them are completed, shifts to the next thermal terminal test operation. This is shown in a time chart in FIG.

According to the automatic trial run system of the prior art, the heating trial run and the cooling trial run do not occur at the same time. Therefore, as is apparent from the time chart of FIG. 11, in the conventional automatic test operation device, the total time required for the heating test operation of all terminals and the total time required for the cooling test operation of all terminals is required for the test operation. Therefore, the conventional automatic test run system has a problem that it takes a considerably long time to complete all the steps of the test run.

In addition, in the prior art automatic test operation device, although the display indicates that the automatic test operation is currently being performed, there is a problem that it is not possible to know at which stage the automatic test operation is currently performed. . Therefore, the operator has no idea when the automatic test run will end, and has no other way than to wait for the end, and there is a problem that another work such as repairing the piping cannot be performed during that time.

That is, according to the automatic test run system of the prior art,
Since the time required for the trial run is long and, in addition, another work cannot be performed during that time, the work setup of the automatic trial run is extremely poor, and there is a problem that the trial run takes a significantly long time as a whole.

Therefore, the present invention pays attention to the above-mentioned drawbacks of the prior art, improves the automatic trial run device, shortens the time required for the trial run, and gives the operator a suggestion as to the end time of the automatic trial run, thereby providing an air conditioning system. The objective is to enable reduction of the total time required for the trial operation of.

[0017]

A feature of the present invention for achieving the above object is to provide a heating test operation in an automatic test operation apparatus for an air conditioning equipment having a plurality of thermal terminals having at least either a cooling function or a heating function. A heating trial operation control function for controlling the heating trial operation, and a cooling trial operation control function capable of operating at the same time as the heating trial operation control function for controlling the cooling trial operation, and heating one thermal terminal or cooling another thermal terminal during the cooling trial operation or It is located in the automatic test run system for air conditioning equipment that allows for heating test runs.

Further, the invention further improved on the above-mentioned invention is characterized in that at least one of the heating trial operation control function and the cooling trial operation control function, and the trial operation control function is provided while the thermal terminal is performing the trial operation by the other trial operation control function. It is an automatic test operation device for heating and cooling equipment having a thermal terminal selection function that does not perform test operation.

Another aspect of the present invention for achieving the above-mentioned object is an automatic test operation device for a heating / cooling facility, which comprises a plurality of thermal terminals having at least either a cooling function or a heating function, and which has a plurality of connected thermal terminals. In one having a function of automatically performing a cooling test operation and a heating test operation according to a certain procedure, a display of the thermal terminal and a display device for displaying the current test operation status of the thermal terminal are provided, and the display of the display device is The automatic test operation device is characterized in that the thermal terminal is switched at regular intervals.

[0020]

The automatic test-driving apparatus according to the first aspect of the invention has a heating test-running control function and a cooling test-running control function, and both of them can operate at the same time. Therefore, during the heating test operation of one heat terminal, the cooling test operation of the other heat terminal can be performed.

In addition, the automatic test run device according to claim 2 is
Since the thermal terminal is provided with the heat terminal selection function, the same thermal terminal is not subjected to the cooling test operation while the heating terminal is in the heating test operation, for example. On the contrary, the same thermal terminal is not subjected to the heating test operation during the cooling test operation.
Therefore, in the automatic test operation device according to the second aspect, the heating test operation and the cooling test operation are not simultaneously performed on one heat terminal, and an erroneous determination does not occur in the test operation result.

Further, since the automatic test-run device according to the third aspect has the display device for displaying the thermal terminal and the current test-run status of the thermal terminal, the operator can grasp the progress of the test-run. Further, since the display of the display device is performed by changing the thermal terminal at regular time intervals, a large space is not required in the display section.

The automatic test operation device for air conditioning equipment of this embodiment is adopted for the central heating shown in FIG. And the control device 40 of the automatic test drive device
Is equipped with a CPU, a ROM and a RAM and is built in the main controller 31.

The ROM of the control device 40 stores a control program for automatic test operation shown in the flow chart of FIG. 1 and a display program shown in the flow chart of FIG. 5, which will be described later. Further, the quality of the test operation result of each thermal terminal is stored in the RAM separately for the heating test and the cooling test.

A test run switch 41, a test run recheck switch 43, and a display device 45 are attached to the main controller 31. And these are all control devices 4
It is connected to 0. Here, the trial run switch 41 is a switch for starting and stopping the trial run. On the other hand, the trial run recheck switch 43 is connected when testing all the thermal terminals again. When the test run recheck switch 43 is connected, the R of the control device 40 is connected as described later.
The test run results of each thermal terminal stored in the AM are deleted.

The display device 45 displays the progress of the trial run during the automatic trial run described later, and has a liquid crystal display device (LCD).

The signals of the temperature detectors 15 and 20 are input to the control device 40 of the main controller 31. Further, sub-controllers 32, 33, 34, 35, 36 of the thermal terminals 2, 3, 4, 5, 6 are connected to the control device 40. From the control device 40 to each sub-controller 3
A signal for opening and closing the thermal valve 23 and the like, a signal for starting the refrigerator and the fan, a command signal for confirming the generation of hot air and cold air, and the like are transmitted to 2 and the like. On the contrary, a signal from a temperature detector (not shown) such as each thermal terminal 2 is transmitted from each sub-controller 32 or the like to the control device 40.

Next, the control process of the automatic test run system of this embodiment will be described with reference to FIG. The trial run this time is assumed to have been performed first after the pipe construction. The control process of the automatic test run system of this embodiment is based on STEP 1 depicted on the left side of FIG.
To STEP9, and a series of cooling trial operation steps from STEP10 to STEP18, which are also depicted on the right side of FIG. That is, in the control program shown in this embodiment, STEP 1 to STEP 9 fulfill the heating trial operation control function, and STEP 10 to STE.
Up to P18 fulfills the cooling test operation control function. What is particularly noteworthy in the automatic test run system of this embodiment is that the heating test run control process and the cooling test run control process both proceed in parallel at the same time.

That is, the operation of the automatic test run system starts by activating the test run switch 41 of the main controller 31. When the test run switch 41 is activated, S
The heating connection terminal confirmation step of TEP1 and the cooling connection terminal confirmation step of STEP10 are started at the same time, and the steps below the flowchart continue.

In order to simplify the description, the steps on the heating trial run side will be described first. When the test operation switch 41 is activated, STEP 1 is performed, and the thermal terminal having the heating function is confirmed. That is, in this embodiment, the thermal terminals 2, 3, 4,
It is confirmed that the heating terminals 5 and 6 have the heating function, and it is recognized that the heating trial operation from STEP 1 to STEP 9 is performed on the thermal terminal.

Then, in STEP 2, it is determined whether the trial run recheck switch 43 is connected. If the test run recheck switch 43 is not connected,
Proceed to STEP4. In STEP4, the thermal terminal whose result of the previous test operation was good is confirmed. That is, the data of the result of the previous test run stored in the RAM is read and confirmed. Since the trial run this time was the first to be performed after the pipe construction, there was no record of the thermal terminal that was good in the RAM data. In the next STEP5, the thermal terminals confirmed in STEP1 are sequentially selected. Specifically, the thermal terminal 2, which is the first thermal terminal, is selected.

Then, in STEP 6, it is determined whether or not the thermal terminal 2 selected in STEP 5 was good in the previous heating test operation. This test is not good because it is the first test after the pipe construction as described above, and the process proceeds to the next STEP 7.

Here, in STEP 7, it is determined whether or not the selected thermal terminal is currently in the cooling test operation.
This is a process that performs a heat terminal selection function. That is, if the thermal terminal is in the middle of the cooling trial run in the process on the right side of FIG. 1, in order to prevent malfunction of the cooling trial run, S
Return to TEP5 and select another thermal terminal. On the other hand, if the selected heat terminal is not currently in the cooling test operation, the process proceeds to STEP 8 and the heating test operation is performed.

The specific contents of the heating test operation are substantially the same as those described in the prior art. That is, the control device 40 sends a signal to the sub-controller 32 to open the thermal valve 23. Specifically, a signal for raising the temperature setting of the sub controller 32 or the like is transmitted from the control device 40 to the sub controller 32. The sub-controller 32 is
Upon receiving the above-mentioned signal, the relay that heats the thermal valve 23 is activated. It should be noted that the signal for opening the thermal valve 23 does not go through the sub-controller 32 but is directly sent to the main controller 3
It may be emitted from 1 to the relay which heats the thermal valve 23.

Simultaneously with the transmission of the signal for opening the thermal valve 23, the timer starts counting. Until the timer finishes measuring a certain time, the control device 40 monitors the discharge temperature of the water heater detected by the temperature detector 15 and the temperature of the return hot water detected by the temperature detector 20, Calculate the temperature difference.

Monitoring of both temperatures is continued for a certain period of time based on a timer, and after the certain period of time, regardless of whether there is a temperature difference or not, a signal for closing the thermal valve 23 is transmitted and the heating trial operation is completed. To do. Then, if the detected temperatures of the temperature detector 15 and the temperature detector 20 differ by a certain amount or more within a certain period of time, the thermal terminal is determined to have a good test operation result. On the contrary, if the predetermined temperature difference does not occur within the fixed time, it is determined that the test operation result is not obtained. Then, this determination result is temporarily stored. When heating trial run ends, the next STEP 9
Then, it is judged whether the trial run of all the thermal terminals is completed.

In the present example, since the heating trial operation of the thermal terminal 2 has just ended, the process returns to STEP 5. Then, the series of control cycles described above is performed by the thermal terminal 3 whose connection is confirmed.
This is repeated for 4, 5, and 6. Also the thermal terminal 3,
When performing the series of control cycles described above for Nos. 4, 5, and 6, when the thermal terminals selected in STEP 5 happen to be simultaneously engaged in the cooling test operation and it is determined in STEP 7 that the cooling test operation is in progress, As done STEP5
Go back to and select another thermal terminal. Then, in STEP 7, the thermal terminal determined to be in the cooling test operation is finally selected again and the heating test operation is performed.

During the above-described control of the heating test operation from STEP 1 to STEP 9, at the same time, STEP 10 to S
The cooling trial operation process up to TEP 18 is executed. That is S
Only the connected thermal terminals having the cooling function are confirmed in TEP10. Then, in STEP 11, it is determined whether the trial run recheck switch 43 is connected. If the trial run recheck switch 43 is not connected, the STE
Go to P13. In STEP 13, the thermal terminal which was good in the cooling trial operation in the previous trial operation is confirmed.

When it is confirmed in STEP 13 that the heat terminal which has been good in the cooling test operation is confirmed, the process proceeds to STEP 14, but in the process of the cooling test operation, the first terminal is selected in relation to other devices. Only for the first time, the heating trial operation is waited until the first trial operation is completed. More specifically, the control cycle from STEP1 to STEP9 described above is once ended, and the process returns to STEP5 to select the second thermal terminal and at the same time, the terminal selection for the cooling test operation (STEP14) is executed. It In this way, the terminal selection time is shifted only in the case of the first selection, and once in STEP 18, the terminal selection by the second and subsequent control cycles does not have the waiting time as described above.

Then, in STEP 14, all the thermal terminals having the cooling function are sequentially selected. Since the current control cycle is the first cycle, the thermal terminal 2 will be selected. In the next STEP 15, it is determined whether or not the previous cooling trial operation of the selected thermal terminal was good. And if the previous cooling trial run is good, STE
Skip the cooling trial operation of P17 and move to STEP18. If the previous cooling trial run is not good, the next ST
Proceed to EP16.

In STEP 16, it is determined whether or not the selected thermal terminal is currently in the heating trial operation, as in STEP 7 described above. If the thermal terminal is in the heating trial run, in order to prevent malfunction of the trial run, STEP14
Return to and select another thermal terminal. On the other hand, if the selected thermal terminal is not currently in the heating trial operation, proceed to STEP 17,
A cooling test run is performed.

In the cooling test operation, from the control device 40 of the main controller 31 to the sub controller 32,
A signal for starting the refrigerator and the fan and a command signal for confirming the generation of cold air are transmitted. Sub controller 32
Then, when the above signal is received, the cooling trial run is performed by the original program. Then, together with signals such as the temperature of the cold air, the result of the cooling test operation performed by the original program is transmitted to the control device 40 of the main controller 31. The execution time of the cooling test operation is set to be exactly the same as the execution time of the heating test operation described above.

The result of the cooling trial operation is temporarily stored, and then the process proceeds to STEP 18 to judge whether the cooling trial operation of all the heat terminals has been completed. Then, if there is a thermal terminal that has not yet been subjected to the cooling test operation, the process returns to STEP 14 and the above steps are repeated.

When both the heating test operation process from STEP 1 to STEP 9 and the cooling test operation process from STEP 10 to STEP 18 are completed, STEP
The process proceeds from 19 to STEP 20, and the result of the trial run is stored in the RAM. Then, after that, the automatic test operation is ended.

When the operation of the automatic test run system of this embodiment is examined with a time chart, it is as shown in FIG. That is, when the trial run switch 41 is activated, the heating trial run side controls
Proceeding from STEP 1 to STEP 5, the first thermal terminal 2 is selected. At this time, in the control on the cooling trial run side, the STE
Although the process proceeds from P10 to STEP13, as described above, the first selection is performed after one cycle of the heating test operation is completed, and therefore the control on the cooling test operation side is waiting in STEP13.

On the other hand, the heating trial run side goes through STEP 6 to S
Reach TEP7. Here, it is confirmed whether the thermal terminal 2 is performing the cooling test operation. As described above, the cooling test operation is waiting in STEP 13 and the thermal terminal 2 is not in the cooling test operation. Therefore, the process proceeds to STEP 8 and the heating terminal 2 is subjected to the heating test operation as shown in the time chart. Then, in the control on the heating trial operation side, the process returns from STEP 9 to STEP 5.
Further, on the heating trial operation side, STEP 5 functions again to select the next thermal terminal 3. On the other hand, the control on the cooling trial run side is released from standby, and in STEP 14, the first heat terminal, which is the heat terminal 2
Select. Then, the heating test run goes through STEP 6 and S
On the other hand, the process proceeds to TEP7, and on the other hand, on the cooling trial operation side, the process proceeds from STEP15 to STEP16.

Here, on the heating trial operation side, it is confirmed whether or not the thermal terminal 3 is performing the cooling trial operation. On the other hand, on the cooling trial operation side, it is confirmed whether or not the thermal terminal 2 is performing the heating trial operation. As is clear from the time chart of FIG. 3, neither thermal terminal 2 nor 3 is performing the trial run of the other. Therefore, as shown in the time chart of FIG. 3, the heating test run of the thermal terminal 3 is started, and the cooling test run of the thermal terminal 2 is started.
In the automatic test operation device of this embodiment, the heating trial operation time and the cooling trial operation time are set to be the same, so that the heating trial operation of the thermal terminal 3 and the cooling trial operation of the thermal terminal 2 are finished at the same time. Therefore, the control on the heating trial run side and the control on the cooling trial run side are performed simultaneously at STEP 5 and STE, respectively.
Returning to P14, the next control cycle is executed. In the next control cycle, the thermal terminal 4 is subjected to the heating test operation, and the thermal terminal 3
Will be air-conditioned for trial run. Further, in the next control cycle, the heat terminal 5 is subjected to the heating test operation, and the heat terminal 4 is subjected to the cooling test operation. In the next cycle, the thermal terminal 6 is selected in STEP5.

At the same time, the thermal terminal 6 has not been subjected to the cooling test operation, so the routine proceeds to STEP 9 where the thermal terminal 6 is subjected to the heating test operation. On the other hand, even in the control on the cooling trial run side, STEP
At 14, the thermal terminals 6 are simultaneously selected. That is, on the cooling trial operation side, the thermal terminals 2, 3 and 4 are sequentially selected, but the thermal terminal 5 does not have the cooling function. Therefore, it is not confirmed in the process of STEP10, and the thermal terminal 5 is not selected in STEP14. Therefore, in this control cycle, STE
By executing P14, the thermal terminal 6 is selected. And STE
In P16, it is determined whether the thermal terminal 6 is in the heating test operation.

By the way, as described above, the thermal terminal 6 has the ST
It was selected earlier in EP5 and the heating commissioning is already pending. Therefore, on the cooling trial run side, STEP 16 to S
Return to TEP14. Then, since the heat terminal 6 is selected again, the cooling trial operation side continues to perform STEP16, STEP14, STEP15 until the heating trial operation of the heat terminal 6 ends.
The above process is repeated and the process stands by in STEP 16. When the heating trial operation of the heat terminal 6 is completed, the process proceeds to STEP 17 and the cooling trial operation of the heat terminal 6 is performed. And STEP
The procedure moves from 19 to STEP 20, and the automatic test run ends. The automatic test operation apparatus of the present embodiment has the effect of considerably shortening the time required for automatic test operation, as is clear from a comparison between the time chart of FIG. 3 and the time chart of FIG. 11 according to the prior art.

During the above-described test operation, the current status of each thermal terminal is displayed on the display device of the main controller 31. Specifically, the status of the trial run is displayed on the clock display unit 46 of the display device 45 with a three-digit symbol, the current status is displayed in the first digit, and the thermal terminal number is displayed in the second digit and the third digit. Is displayed. Then, this display is repeatedly displayed until, for example, the thermal terminal is automatically switched every one second and the test operation switch 41 is released. The symbols for the test run status are shown in Table 1
Is the street.

[0052]

[Table 1]

Here, the control of the status display of the trial run will be described with reference to the flowchart of FIG. The control of the status display is automatically performed at the same time as the start of the automatic test run. That is, when the test operation switch 41 is activated, STEP 30 is started, and the clock display unit 46 of the display device 45 immediately changes the display. That is, in STEP 30, the current status of the thermal terminal 2 is displayed. For example, if the thermal terminal 2 is in the heating trial operation, "02H" is displayed on the clock display unit 46.
Then, the display of the thermal terminal 2 continues for 1 second, for example, and then STE
The process moves to P31 and the current status of the thermal terminal 3 is displayed.
Then, the thermal terminals are switched one after another every second, and the current status of each is displayed.

From STEP 30 to STEP 34,
When the display of all the thermal terminals is completed, it is determined whether the trial run switch 41 is released. If the trial run switch 41 is not released, the process returns to STEP 30 and the display is performed in the order described above. When time passes and automatic test operation proceeds, the clock display section 46 displays “03F” and “04E”.
Valid information such as "05H" and "060" is displayed. And this display is continued unless the trial run switch 41 is turned off.

In the above embodiment, the STE on the cooling trial run side is used.
Select the first thermal terminal in P14 as the heating trial run 1
The measures to be taken after the cycle has been illustrated. However, if the performance of the equipment used permits, it is of course possible to control the selection of the first thermal terminal simultaneously with the heating side.
FIG. 6 is a time chart when the heating side and the cooling side simultaneously select the first thermal terminal. When the heating test operation side and the cooling test operation side simultaneously select the thermal terminals in STEPs 5 and 14, respectively, the thermal terminal 2 is selected in the first selection. Here, if the heating trial operation of both trial operations is prioritized, the heating trial operation of the thermal terminal 2 is performed via STEPs 6 and 7 in the control on the heating trial operation side. On the other hand, on the cooling trial operation side, it is determined in STEP 16 that the heating trial operation is being performed, the process returns to STEP 14 and the heat terminal is selected again. Then, the thermal terminal 3 is selected as the next thermal terminal, and the thermal terminal 3 is subjected to the cooling test operation. Then, as shown in the time chart, the heat terminal 3 is subjected to the heating test operation, and the heat terminal 4 is subjected to the cooling test operation. In the next cycle, the heat terminal 4 is subjected to the heating test operation, while the heat terminal 6 is subjected to the test operation on the cooling test operation side.

Then, in the next cycle, the thermal terminal 5 is subjected to the heating trial operation. Here, on the cooling test operation side, the selection of the thermal terminal has already completed, so during the first control cycle, the thermal terminal 2 skipped the cooling test operation is selected again, and the thermal terminal 2 is set to the cooling test operation. To be done. Then, in the last cycle, the heating terminal 6 is subjected to the heating trial operation.

In the above embodiments, the heating trial operation side and the cooling trial operation side each have a configuration in which one thermal terminal is selected and one trial operation is performed. Regarding the heating test operation, in the piping circuit of FIG. 9, the return hot water of each heat terminal is collected in the collecting pipe 28, and the heating test operation of all the heat terminals is performed by only one temperature detector 20, so the piping circuit This is because the heating trial run has to be performed for each thermal terminal due to the above restrictions.

On the other hand, the cooling test operation does not have the above-mentioned restrictions, and is merely in step with the heating-side test operation. Therefore, if the capacity of the control device permits, it is possible to simultaneously perform the cooling trial operation of two or more thermal terminals.
For example, in the case of performing a cooling trial operation of two thermal terminals at a time, in STEP14 of FIG. 1, two thermal terminals are selected at a time, and in STEP16, it is determined whether or not the heating trial operation is individually performed for each thermal terminal. Further, in STEP 17, it is possible to issue the cooling trial operation command to the two thermal terminals at the same time.

FIG. 7 shows a time chart when the cooling trial operation of two thermal terminals is simultaneously performed. When adopting the control method of selecting two thermal terminals at once,
In the first control cycle, the thermal terminal 2 is subjected to the heating trial operation as in the previous embodiment. Then, the cooling test operation is performed on two of the remaining thermal terminals, more specifically, the thermal terminals 3 and 4. In the next control cycle, the thermal terminal 3 is subjected to the heating trial operation, and the thermal terminals 2 and 6 are subjected to the cooling trial operation. In addition, the piping circuit itself is changed so that each heat terminal 2 or the like is connected to the collective piping 28
Assuming that temperature detectors are installed between
The heating test operation can be performed simultaneously for two or more thermal terminals.

In each of the above embodiments, the heating trial run time and the cooling trial run time are unified, and both trial runs are performed at the same time. However, the present invention is not limited to the one in which the execution time of such a test operation is unified, and both may be executed only at different times. For example, in the heating trial operation, it is also preferable to end the heating trial operation immediately when a certain difference is detected between the discharge temperature of the water heater detected by the temperature detector 15 and the return hot water temperature detected by the temperature detector 20. . FIG. 8 exemplifies a time chart in the case where the heating test operation and the cooling test operation are performed for different times.

On the contrary, in the case of strictly controlling the heating trial run time and the cooling trial run time,
The step of confirming whether or not the other test operation described in the flowchart of 1) is being performed, that is, the steps of STEP 7 and STEP 16 are not always necessary. Specifically, as explained in the flowchart of FIG. 1, the heating trial run time and the cooling trial run time are unified or individually managed strictly, and the thermal terminal trial run must be performed within that time. I will finish. Theoretically, if the start time and end time of the heating test operation of a specific heat terminal and that of the cooling test operation of the same heat terminal are offset, the same heat terminal can be involved in the heating test operation and the cooling test operation at the same time. impossible.

For example, the time chart illustrated in FIG. 3 is stored in the control device 40 in advance, and a heating test operation and a cooling test operation are commanded to the sub-controller 32 and the like according to the order of the time chart. Then, the thermal terminal 2 is first subjected to the heating trial operation. Then, when the heating trial run of the thermal terminal 2 is finished, the thermal trial run of the thermal terminal 2 is performed this time. At the same time, the next thermal terminal 3 is subjected to heating trial operation. In this way, the thermal terminals whose heating trial operations have ended one after another are subjected to the cooling trial operation, the next thermal terminal is selected, and the selected thermal terminals are subjected to the heating trial operation. Then, finally, the heating test operation and the cooling test operation of all the thermal terminals are smoothly performed.

In the automatic test run system of this embodiment described with reference to the flowchart of FIG. 1, the test run result is R in STEP 20.
It has a function to store in AM, and STEP4, STE
In P13, the thermal terminal having the good result of the previous trial run was confirmed, and in STEP6 and STEP17, the one having the good trial run of the last time disclosed the one having the control function of not performing the trial run this time. By having such a control function,
In the automatic commissioning apparatus of the present embodiment, during the second and subsequent trial runs, the thermal terminal that has been good in the previous trial run is automatically excluded from the trial run targets. Therefore, the automatic test operation device of the present embodiment has a peculiar effect that the second and subsequent automatic test operations can be performed in a short time.

Further, the trial run recheck switch 43 is connected when the trial run is desired to be performed again, including the thermal terminals whose results were good in the previous trial run. When the trial run recheck switch 43 is connected, S in the above flowchart
Transition from TEP2 to STEP3, RA of control device 40
The test run result of each thermal terminal stored in M is deleted. Therefore, in STEP 4, it is determined that there is no heat terminal that was good in the previous test operation, and the heating test operation and the cooling test operation are performed for all the heat terminals.
