- the report judging means 11d reports the detection report of the abnormal operation detecting means when judging that the abnormal operation detection result is not equal to the same abnormal operation content of the same unit based upon the storage result of the storage means 11c, whereas the report judging means 11d does not report the detection report when judging that the abnormal operation detection result is equal to the same abnormal operation content of the same unit.
- Fig. 3 is a diagram for representing an example of a flow operation of the abnormal operation reporting process executed in this embodiment 1.
- the report judging means 11d retrieves the abnormal operation content of this air conditioner from the storage results of the storage means 11c based on this detection result (step S2).
- the report judging means 11d compares this retrieved result with the content of the detection result to thereby judge as to whether or not this retrieved result is equal to the same abnormal operation content of the same unit (step S3).
- this abnormal operation content is reported to the reporting means 11b and the storage means 11c. As a result, this abnormal operation content is transmitted via the public line to the remote monitoring terminal unit 7, and also is stored in the storage means 11c (steps S4 and S5).
- the report judging means 11d does not report (output) this same abnormal operation content of the same unit to the reporting means 11b and the storage means 11c.
- this same abnormal operation content is not reported via the public line to the remote monitoring terminal unit 7, but also is not stored in the storage means 11c (step S6).
- the abnormal operation condition is solved by a serviceman, if the abnormal operation content stored in the storage means 11c can be cleared by the abnormal operation content clear means 14, then when the same abnormal operation subsequently happens to occur, the monitoring apparatus reports this same abnormal operation to the remote monitoring terminal unit.
- the cooling apparatus can check as to whether or not the repair is completed, and whether or not the repair operation can give the good result.
- Fig. 4 is a block diagram for representing an arrangement of an operation monitoring apparatus according to an embodiment 2 of the present invention.
- the operation monitoring apparatus of the drawing is equipped with the reporting means 11b, the storage means 11c, and a timer 15 for producing a time instant to report selecting means 11e and the like (will be explained later).
- the microcomputer 11 is equipped with, in addition to the arrangement shown in the embodiment 1, data rewriting means 11f, and report selecting means 11e.
- the data rewriting means 11f rewrites the data stored in the storage means every time preselected time has passed.
- the report selecting means 11e further investigates time elapsed from the previous reporting time instant so as to judge as to whether or not preselected time has passed. Also, only when the preselected time has passed, this report selecting means 11e issues the report.
- the reporting time instant produced from the timer 15 is stored into the storage means 11c according to this embodiment.
- the report judging means 11d retrieves the abnormal operation content of this air conditioner from the storage results of the storage means 11c based on this detection result (step S12).
- the report judging means 11d compares this retrieved result with the content of the detection result to thereby judge as to whether or not this retrieved result is equal to the same abnormal operation content of the same unit (step S13).
- this abnormal operation content is reported to the reporting means 11b and the storage means 11c.
- this abnormal operation content is transmitted via the report selecting means 11e and the public line to the remote monitoring terminal unit 7, and also is stored in the storage means 11c (steps S14 and S15).
- the reporting means 11b since the time instant is produced from the timer 15 to be supplied to the reporting means 11b and the storage means 11c, the reporting means 11b also reports such a time instant when the abnormal operation happens to occur. Also, the storage means 11c stores therein the abnormal operation content and this time instant when the abnormal operation happens to occur.
- the report judging means 11d does not report this abnormal operation content to the reporting means 11b and the storage means 11c, but reports this abnormal operation content to the report selecting means 11e (step S16).
- the report selecting means 11e calculates a time difference between the previous reporting time instant stored in the storage means 11c and the present time instant produced from the timer 15, and then compares this calculation result with preset report prohibit time "T1".
- the report selecting means 11e reports both the present time instant and the abnormal operation content to the reporting means 11b and the rewriting means 11f.
- the reporting means 11b again sends the present time instant and the same abnormal operation content to the remote monitoring terminal unit 7.
- the storage means 11c stores therein the present time instant, and such a fact that the previous abnormal operation content occurs at the present time instant (steps S17 and S18).
- both the present time instant and the abnormal operation content are not reported to the reporting means 11b and the rewriting means 11f. Accordingly, both the previous time instant and the abnormal operation content are stored in the storage means 11c (step S19).
- this abnormal operation is reported after the time difference (recurrence time) between the previous reporting time instant and the previous time instant exceeds the report prohibit setting time T1.
- time difference time between the previous reporting time instant and the previous time instant exceeds the report prohibit setting time T1.
- such temporal abnormal operations caused by changes in weather and environments are not reported to the remote monitoring terminal unit. That is, for instance, in particular, the temperature around the installation place of the outdoor units is increased due to some weather and environmental conditions.
- the heat radiation performance of the radiator plate of the outdoor unit is deteriorated, so that the operation of the outdoor unit is stopped under abnormal condition. Thereafter, the deteriorated heat radiation performance is improved due to changes in the succeeding weather and environmental conditions, so that the automatic recovery operation can be performed.
- this report prohibit setting time T1 may be set depending upon the content of the abnormal operation, this report prohibit setting time is variable depending upon the use conditions of the air conditioner, and the contents of the abnormal operations. Therefore, it is possible to obtain a more useful remote monitoring system for the cooling apparatus.
- the report prohibit setting time T1 may be arbitrarily set by way of the remote monitoring terminal 7, then the use condition of the air conditioner and the content of the abnormal operation can be varied even when the operator goes to the installation place of the air conditioner. As a result, it is possible to provide a more useful remote monitoring system for the cooling apparatus.

- the clear means 11h automatically clears the content stored in the storage means 11c based on the judgment result of this clear judging means 11g when the time difference between the previous reporting time instant and the present reporting time instant exceeds the preset clear time T2.
- the report judging means 11d retrieves the abnormal operation content of this air conditioner from the storage results of the storage means 11c based on this detection result (step S22).
- the report judging means 11d compares this retrieved result with the content of the detection result to thereby judge as to whether or not this retrieved result is equal to the same abnormal operation content of the same unit (step S23).
- this abnormal operation content is reported to the reporting means 11b and the storage means 11c. As a result, this abnormal operation content is transmitted via the public line to the remote monitoring terminal unit 7, and also is stored in the storage means 11c (steps S24 and S25).
- the reporting means 11b since the time instant is produced from the timer 15 to be supplied to the reporting means 11b and the storage means 11c, the reporting means 11b also reports such a time instant when the abnormal operation happens to occur. Also, the storage means 11c stores therein the abnormal operation content and this time instant when the abnormal operation happens to occur.
- the report judging means 11d does not report this same abnormal operation content of the same unit to the reporting means 11b and the storage means 11c (step S26).
- the clear judging means 11g will check the time lapse of the abnormal operation content stored in the storage means 11c and detected by the detecting means based upon the time instant produced from the timer 15 every predetermined time.
- the clear judging means 11g calculates a time difference (time lapse) between this reporting time instant and the time instant produced from the timer 15, and compares this calculation result with the preset clear time T2. Based on this comparison result, when the time difference exceeds the preset clear time T2, the clear judging means 11g reports the time up content to the clear means 11h (steps S31 and S32).
- the clear means 11h clears the abnormal operation content thereof and the reporting time instant stored in the storage means 11c. That is to say, the clear means 11h deletes the abnormal operation content exceeding the preset clear time T2 from the storage means 11c, and the flow operation is returned to the first step (step S33).
- this clear time is variable depending upon the use conditions of the air conditioner, and the contents of the abnormal operations. Therefore, it is possible to obtain a more useful remote monitoring system for the cooling apparatus.
- the preset clear time T2 may be arbitrarily set by way of the remote monitoring terminal 7, then this preset clear time T2 can be varied based on the use condition of the air conditioner and the content of the abnormal operation even when the operator goes to the installation place of the air conditioner. As a result, it is possible to provide a more useful remote monitoring system for the cooling apparatus.
- a clear judging means 11g is employed instead of the report selecting means 11e employed in the embodiment 2.
- This clear judging means 11g judges as to whether or not the time lapse after the abnormal operation stored in the storage means has been reported passes through the preset clear time "T2".
- both the clear judging means 11g and the clear means 11h are merely added.
- such a clear means 11h is not employed instead of the rewriting means.
- This clear means 11h automatically clears the storage content of the storage means 11c when the time lapse after the report exceeds the preset clear time T2 based on the judgment result of this clear judging means 11g.
- this report judging means reports to the report selecting means.
- this report judging means judges that the time after the report exceeds the judging time T3
- this report judging means reports to the clear judging means.
- Fig. 9 schematically indicates an arrangement of an operation monitoring apparatus according to an embodiment 5 corresponding to "3" of the present invention.
- the arrangement of this embodiment 5 is made by adding to the arrangement of the embodiment 3, a detecting time judging means 11i for judging as to whether or not a detecting time is reached to a preset time "N".
- This preset time "N” is retrieved from the storage region of the storage means 11c, while this storage means 11c temporarily stores the same abnormal operation content of the same unit and the detecting time thereof.
- the report judging means 11d retrieves the abnormal operation content of this air conditioner from the storage results of the storage means 11c based on this detection result (step S42).
- the report judging means 11d compares this retrieved result with the content of the detection result to thereby judge as to whether or not this retrieved result is equal to the same abnormal operation content of the same unit. If the retrieved result content is equal to the same abnormal operation content, then the report judging means 11d instructs a rewriting means (not shown) of the storage means to increment this detecting time of the storage means, and further instructs the detecting time judging means 11i to execute the judgment (step S43 and S44).
- the report judging means 11d judges as to whether or not the detection result content is equal to the same abnormal operation content of the same unit. If not, then the report judging means 11d instructs the rewriting means to store the abnormal operation content of this air conditioner, the detecting time "1", and also the abnormal operation detecting time instant into the storage means 11c (step S45).
- the detecting time judging means 11i confirms the detecting time of this abnormal operation content from the storage result of the storage means 11c.
- the report judging means 11d judges that this confirmed detecting time is reached to a preset time "N"
- the report judging means 11d instructs the reporting means 11b to report this abnormal operation content to the remote monitoring terminal unit 7 (steps S46, S47 and S48).
- the detecting time judging means 11i instructs the clear means 11h to delete this abnormal operation content from the storage means 11c (step S49).
- the abnormal operation is reported to the remote monitoring terminal unit.
- a temporal abnormal operation with a less significant degree is not reported, which suddenly and not periodically occurs due to changes in weather conditions.
- only the continuous abnormal operation content is reported.
- it is possible to provide a low-cost remote monitoring system having high reliability for the cooling apparatus which can correctly separate the temporal abnormal operation from the continuous abnormal operation and can correctly monitor this continuous abnormal operation, while reducing the total number of reporting the abnormal operations.
- the detecting time judging means deletes the abnormal operation content thereof from the storage means.
- the storage capacity of the storage means is reduced.
- the detecting time judging means judges that the occurrence time of the abnormal operation is reached to a preset detecting time within preselected time (preset time T4) based upon the time instant produced from the timer 15, the abnormal operation content thereof is reported to the remote monitoring terminal unit 7. Since the detecting time judging means discriminates the temporal abnormal operation from the continuous abnormal operation based on the detecting times within the predetermined time, and then reports, it is possible to obtain such a remote monitoring system with high reliability for the cooling apparatus, for correctly judging and reporting the abnormal operation.
- this report judging means 11d may instruct the clear means 11h to clear this abnormal operation content from the storage means 11c.
- the report prohibit setting time T1 may be arbitrarily set by way of the remote monitoring terminal 7, then the use condition of the air conditioner and the content of the abnormal operation can be varied even when the operator goes to the installation place of the air conditioner. As a result, it is possible to provide a more useful remote monitoring system for the cooling apparatus.
- Fig. 11 is a diagram for showing an arrangement of an embodiment 6 according to the present invention.

- the reporting destination selecting means 11j compares the detection result of this abnormal operation detecting means 11a with an abnormal operation of each of the air conditioners in a reporting destination designation table, and selects any one of these remote monitoring terminal units to be reported based on this comparison result.
- the arrangement other than a timer 15 instead of the clear means 11h employed in the embodiment 1 is the same as that of the embodiment 1.
- the reporting destination designating means 11j compares this transmitted abnormal content of the air conditioner with, for instance, the abnormal operation contents of the respective air conditioners contained in the reporting destination designation table shown in Fig. 12. Based on this comparison result, the reporting destination designating means 11j selects any one of these remote monitoring terminals, and then transmits this selection result to the reporting means 11b.
- the reporting means 11(b) transmits (reports) the abnormal operation content of the air conditioner detected by the abnormal operation detecting means 11a to the remote monitoring terminal unit selected by the reporting destination designating means 11j.
- reporting destination designation table a plurality of reporting destinations may be designated, and otherwise, no reporting destination may be designated, depending upon the importance/significant degrees of the abnormal operation contents, or the occurrence time instants of the abnormal operations. In other words, as to a certain abnormal operation, it is possible to designate that no report is made.
- this abnormal operation content is reported from the operation monitoring apparatus to any of the plural remote monitoring terminal units, depending upon the abnormal operation contents of the operation conditions of the indoor units and the outdoor units, this abnormal operation content is reported to the remote monitoring terminal unit suitable for this abnormal operation content based on the importance/significant degree of the abnormal operation content, or the occurrence time instant of the abnormal operation. As a consequence, it is possible to obtain a very useful remote monitoring system for the cooling apparatus, capable of providing very quick services.
- the reporting destination designating means 11j may detect the occurrence time instant of the abnormal operation content sent from the abnormal operation detecting means 11a. As a result, since it is also possible to select any of these remote monitoring terminal units to be reported based on the occurrence time instant other than the contents of the reporting destination designation table, a further useful remote monitoring system for the cooling apparatus may be accomplished.
- the same abnormal operation of the same unit has been employed as the report judging basis of the report judging means. If an abnormal operation content is not repaired even in a plurality of air conditioners installed in an office, a home, or a building, then this abnormal operation content of this model is not changed. As a consequence, only the condition for judging whether or not the detected abnormal operation content is equal to the same abnormal content may be provided.
- the abnormal operation is reported to the remote monitoring terminal unit.
- a temporal abnormal operation with a less significant degree is not reported, which suddenly and not periodically occurs due to changes in weather conditions.
- only the continuous abnormal operation content is reported.
- it is possible to provide a low-cost remote monitoring system having high reliability for the cooling apparatus which can correctly separate the temporal abnormal operation from the continuous abnormal operation and can correctly monitor this continuous abnormal operation, while reducing the total number of reporting the abnormal operations.
- this abnormal operation is reported after the time difference (recurrence time) between the previous reporting time instant and the previous time instant exceeds the report prohibit setting time T1.
- time difference time between the previous reporting time instant and the previous time instant exceeds the report prohibit setting time T1.
- the clear time T2 is set to be longer than the report prohibit time T1
- this continuous abnormal operation with the significant degree can be surely reported, and thereafter can be deleted by such a high reliable remote monitoring system.
- the clear means for deleting the abnormal operation content is employed, in particular, when the abnormal operation is cleared and the abnormal operation content is deleted by the serviceman, even if the same abnormal operation subsequently happens to occur, this same abnormal operation can be firmly reported. As a consequence, it is also possible to accomplish a high-reliable remote monitoring system with easy operation for the cooling apparatus, which can check as to whether or not the repair is completed, and whether or not the repair operation can give the good result.
- this clear time is variable depending upon the use conditions of the air conditioner, and the contents of the abnormal operations. Therefore, it is possible to obtain a more useful remote monitoring system for the cooling apparatus.
