Fig. 3 is the process flow diagram that illustrates according to air conditioner inspection method of the present invention.As shown in Figure 3, many air-conditionings (300) at first are installed, a plurality of indoor units that these many air-conditionings comprise at least one outdoor unit, are connected to a plurality of MCU of outdoor unit and are connected to each MCU, manually make a plurality of indoor units respectively with the valve of a plurality of MCU coupling (301).In this state, determine whether outdoor temperature is lower than the heating allowable temperature, thereby can carry out heating operation (302).If outdoor temperature is lower than the heating allowable temperature, and therefore can carry out heating operation, carry out inspection (304) by heating operation so.If outdoor temperature is higher than the heating allowable temperature, and therefore heating operation is infeasible, carries out inspection (306) by cooling down operation so.That is to say that when temperature (, outdoor air) was low, for the inspection of air-conditioning installment state, heating operation was more effective than cooling down operation, therefore checks the installation of air conditioners state by heating operation (for example, in winter) when installing and check air-conditioning.When temperature (, outdoor air) was higher, for the inspection of air-conditioning installment state, cooling down operation was more effective than heating operation, therefore checks the installation of air conditioners state by cooling down operation (for example, in summer) when installing and check air-conditioning.
Finish by heating operation (304) check or finish inspection by cooling down operation (306) after, determine whether the installment state of valve and pipeline normal.If determine that the installment state of valve and pipeline is all normal, checked (' being ' of operation 308) so.If determine that the installment state of valve and pipeline is undesired, show that so setup error is with the installment state of notifying examiner's valve and pipeline undesired (310).
Fig. 4 is the diagrammatic sketch that the setup error of checking by the air conditioner inspection method of Fig. 3 is shown.As shown in Figure 4, a plurality of MCU# 10 to #40 are connected to outdoor unit # 1, and a plurality of indoor unit #11-#14 to #41-#44 are connected to MCU# 10 to #40 respectively.The structure of outdoor unit # 1, MCU# 10 to #40 and indoor unit #11-#14 to #41-#44 is identical with the structure of outdoor unit illustrated in figures 1 and 2, MCU and indoor unit.MCU# 10 to #40 controls the operator scheme (cooling or heating operation) of connected indoor unit respectively.
Abnormal pipeline among another setup error 404 indication MCU# 30 shown in Figure 4 connects.By two indoor unit # 32 among the indoor unit # 31 to #34 of MCU# 30 control and the undesired MCU# 30 that is connected to of #33.In this case, when MCU#30 controlled the operation of indoor unit # 32, indoor unit # 33 was operated.Equally, when MCU#30 controlled the operation of indoor unit # 33, indoor unit # 32 was operated.
In Fig. 4, indoor unit # 41 to #44 normal (in other words, correct) is connected to MCU# 40.
Fig. 5 A and Fig. 5 B are the process flow diagrams that is illustrated in the air conditioner inspection method of Fig. 3 by the installment state checking process of heating operation.When outdoor temperature is low, therefore carry out the installment state checking process by heating operation, shown in Fig. 5 A,, determine also whether outdoor temperature is higher than the cooling allowable temperature, thereby can carry out cooling down operation (502) even outdoor temperature is lower.If outdoor temperature is less than or equal to cooling allowable temperature (' denying ' of operation 502), operate all indoor units (504) with the heating operation pattern in the section so at the fixed time.When outdoor temperature was too low, cooling down operation was infeasible, can carry out cooling down operation thereby carry out heating operation with the rising indoor temperature, then by the cooling down operation inspection valve relevant with cooling down operation and the installment state of pipeline.If when temperature is hanged down promptly in winter, check the installation of air conditioners state, can check the installment state of valve and the pipeline relevant so with heating operation by heating operation.Yet, can not check the installment state of valve and the pipeline relevant with cooling down operation.For this reason, although check the installation of air conditioners state by heating operation, cooling down operation is performed in the section at the fixed time, thereby can carry out cooling down operation.Therefore, can check the installment state of valve and the pipeline relevant with cooling down operation.
If outdoor temperature is higher than cooling allowable temperature (' being ' of operation 502) or can carries out cooling down operation by heating operation (504), operate all indoor units (506) with the cooling down operation pattern in the section so at the fixed time.If the cooling down operation of some indoor units is not by normal the execution (' denying ' of operation 508), installation or the mode of operation of determining the cooling valve so are undesired, therefore, not steady for flowing of cooling down operation cold-producing medium, and carry out the registration (510) of cooling off the valve mistake.If the cooling down operation of all indoor units, is determined the installation and the mode of operation normal (512) of cooling valve so by normal the execution (' being ' of operation 508).In this manner, even when carrying out inspection by heating operation, also can be checked through the setup error of cooling valve.
After the installation and mode of operation of checking the cooling valve, each MCU of select progressively (514), and be operatively connected all indoor units to the MCU that selects to check that abnormal pipeline connects (516) between the MCU with the heating operation pattern.If be connected in the indoor unit of MCU of selection some or all not with the heating operation pattern by normal running (' denying ' of operation 518), determine that so the pipeline laying between two or more MCU is undesired, and carry out the registration (520) that the undesired pipeline between a plurality of MCU connects.Undesired pipeline between a plurality of MCU connects and means, setup error 402 as shown in Figure 4 is indicated, the indoor unit that should be connected to a MCU is connected to another MCU, therefore, when all indoor units that are connected to a MCU were attempted heating operation, some or all in the indoor unit were not operated with the heating operation pattern.The inspection of carrying out the undesired pipeline connection between a plurality of MCU continuously is up to all MCU being finished inspection (' denying ' of operation 522).
In the inspection (' being ' of operation 522) of all MCU being finished the undesired pipeline connection between a plurality of MCU afterwards, shown in Fig. 5 B, carry out the inspection that the undesired pipeline in each MCU connects.In order to check that the undesired pipeline among each MCU connects, be each the selection indoor unit (552) among a plurality of MCU.When the heating valve of the indoor unit of selecting and electric expansion valve were closed, the indoor unit of selection was operated (554) with the air blast operator scheme, and unselected indoor unit is operated (556) with the heating operation pattern.For example, for MCU# 10 selects indoor unit # 11, for MCU# 20 selects indoor unit # 21, for MCU#30 selects indoor unit # 31, for MCU#40 selects indoor unit #41.In this manner, be the indoor unit of each selection among a plurality of MCU, thereby the undesired pipeline of carrying out simultaneously each MCU with batch mode connect inspection.If from a plurality of MCU, only select a MCU to check that undesired pipeline connects, can use the plenty of time with the volume check that is connected to the indoor unit of each MCU according to the quantity of MCU so.Yet, according to the present invention, check all MCU simultaneously with batch mode, therefore, reduced the supervision time.
If the indoor unit of selecting does not have with the air blast operator scheme by normal running, perhaps unselected indoor unit does not have with the heating operation pattern by normal running (' denying ' of operation 558), MCU and the pipeline laying between the indoor unit of determining current selection so are undesired, and carry out the registration (560) that the undesired pipeline in the MCU that selects connects.When the indoor unit of selecting with the air blast operator scheme during by normal running, difference is very little between the temperature in of the heat exchanger of the indoor unit of selecting and outlet temperature.Therefore, if the temperature in of the heat exchanger of the indoor unit of selecting and the difference between the outlet temperature less than predeterminated level, determine so indoor unit with the air blast operator scheme by normal running, pipeline connects also normal.Yet, if the indoor unit of selecting with the heating operation pattern but not the air blast operator scheme (in this case, the temperature in of heat exchanger and the difference between the outlet temperature are greater than predeterminated level) be operated, and one of unselected indoor unit is operated with the air blast operator scheme, determines that so the pipeline malunion between two indoor units is normal.Carry out the pipeline laying inspection of the indoor unit that is connected to each MCU continuously, up to all indoor units being finished pipeline laying inspection (' denying ' of operation 562).If all indoor units are not finished the pipeline laying inspection, so among a plurality of MCU each selected next indoor unit, and carry out undesired pipeline by air blast and heating operation and be connected inspection (564).For example, for MCU# 10 selects indoor unit # 12, for MCU# 20 selects indoor unit # 22, for MCU# 30 selects indoor unit # 32, for MCU# 40 selects indoor unit #42.
Fig. 6 A and Fig. 6 B are the process flow diagrams that is illustrated in the air conditioner inspection method of Fig. 3 by the installment state checking process of cooling down operation.When outdoor temperature is higher, therefore carry out the installment state checking process by cooling down operation, as shown in Figure 6A,, determine also whether outdoor temperature is lower than the heating allowable temperature, thereby can carry out heating operation (602) even outdoor temperature is higher.If outdoor temperature is greater than or equal to heating allowable temperature (' denying ' of operation 602), operate all indoor units (604) with the cooling down operation pattern in the section so at the fixed time.When outdoor temperature was too high, heating operation was infeasible, can carry out heating operation thereby carry out cooling down operation to reduce indoor temperature, then by the heating operation inspection valve relevant with heating operation and the installment state of pipeline.If check installation of air conditioners state by cooling down operation when temperature is higher during promptly in summer, can check the installment state of valve and the pipeline relevant so with cooling down operation.Yet, can not check the installment state of valve and the pipeline relevant with heating operation.For this reason, although check the installation of air conditioners state by cooling down operation, heating operation is performed in the section at the fixed time, thereby can carry out heating operation.Therefore, can check the installment state of valve and the pipeline relevant with heating operation.
If outdoor temperature is lower than heating allowable temperature (' being ' of operation 602) or can carries out heating operation by cooling down operation (604), operate all indoor units (606) with the heating operation pattern in the section so at the fixed time.If the heating operation of some indoor units is not by normal the execution (' denying ' of operation 608), installation or the mode of operation of determining heating valve so are undesired, therefore, not steady for flowing of heating operation cold-producing medium, and the registration (610) of execution heating valve mistake.If the heating operation of all indoor units, is determined the installation and the mode of operation normal (612) of heating valve so by normal the execution (' being ' of operation 608).In this manner, even when carrying out inspection by cooling down operation, also can be checked through the setup error of heating valve.
After the installation and mode of operation of checking heating valve, each MCU of select progressively (614), and be operatively connected to all indoor units of the MCU that selects with the cooling down operation pattern, to check that abnormal pipeline connects (616) between the MCU.If be connected in the indoor unit of MCU of selection some or all not with the cooling down operation pattern by normal running (' denying ' of operation 618), determine that so the pipeline laying between two or more MCU is undesired, and carry out the registration (620) that the undesired pipeline between a plurality of MCU connects.Undesired pipeline between a plurality of MCU connects and means, setup error 402 as shown in Figure 4 is indicated, the indoor unit that should be connected to a MCU is connected to another MCU, therefore, when all indoor units that are connected to a MCU were attempted cooling down operation, some or all in the indoor unit were not operated with the cooling down operation pattern.Carry out the inspection that the undesired pipeline between a plurality of MCU connects continuously, up to all MCU being finished inspection (' denying ' of operation 622).
In the inspection (' being ' of operation 622) of all MCU being finished the undesired pipeline connection between a plurality of MCU afterwards, shown in Fig. 6 B, carry out the inspection that the undesired pipeline in each MCU connects.In order to check that the undesired pipeline among each MCU connects, be each the selection indoor unit (652) among a plurality of MCU.When the heating valve of the indoor unit of selecting and electric expansion valve were closed, the indoor unit of selection was operated (654) with the cooling down operation pattern, and unselected indoor unit is operated (656) with the air blast operator scheme.For example, for MCU# 10 selects indoor unit # 11, for MCU# 20 selects indoor unit # 21, for MCU#30 selects indoor unit # 31, for MCU#40 selects indoor unit #41.In this manner, be the indoor unit of each selection among a plurality of MCU, thereby the undesired pipeline of carrying out simultaneously each MCU with batch mode connect inspection.If from a plurality of MCU, only select a MCU to check that undesired pipeline connects, can use the plenty of time with the volume check that is connected to the indoor unit of each MCU according to the quantity of MCU so.Yet, according to the present invention, check all MCU simultaneously with batch mode, therefore, reduced the supervision time.
If the indoor unit of selecting does not have with the cooling down operation pattern by normal running, perhaps unselected indoor unit does not have with the air blast operator scheme by normal running (' denying ' of operation 658), MCU and the pipeline laying between the indoor unit of determining current selection so are undesired, and carry out the registration (660) that the undesired pipeline in the MCU that selects connects.When unselected indoor unit with the air blast operator scheme during by normal running, difference is very little between the temperature in of the heat exchanger of unselected indoor unit and the outlet temperature.Therefore, if the temperature in of the heat exchanger of the indoor unit of selecting and the difference between the outlet temperature less than predeterminated level, determine so indoor unit with the air blast operator scheme by normal running, pipeline connects also normal.
Yet, if one of unselected indoor unit with the cooling down operation pattern but not the air blast operator scheme (in this case, the temperature in of heat exchanger and the difference between the outlet temperature are greater than predeterminated level) be operated, and the indoor unit of selecting is operated with the air blast operator scheme, determines that so the pipeline malunion between two indoor units is normal.Carry out the pipeline laying inspection of the indoor unit that is connected to each MCU continuously, up to all indoor units being finished pipeline laying inspection (' denying ' of operation 662).If all indoor units are not finished the pipeline laying inspection, so among a plurality of MCU each selected next indoor unit, and be connected inspection (664) by cooling and the undesired pipeline of air blast operation execution.For example, for MCU# 10 selects indoor unit # 12, for MCU# 20 selects indoor unit # 22, for MCU# 30 selects indoor unit # 32, for MCU#40 selects indoor unit #42.
When any one in the installment state checking process of execution graph 5A, Fig. 5 B, Fig. 6 A and Fig. 6 B in checked operation found mistake, can will should mistake notify setter or supvr immediately, and can omit other checked operation.
As is apparent from the above description, each MCU is checked that simultaneously the undesired pipeline of indoor unit connects.Therefore, although air-conditioning comprises a large amount of MCU, can reduce the required time of this installation of air conditioners state of checking.
In addition, carry out undesired pipeline connection inspection winter by heating operation when, carry out the bug check of cooling valve by cooling down operation, carry out undesired pipeline connection inspection summer by cooling down operation when, carry out the heating valve bug check by heating operation.Therefore, the present invention has the effect that improves checking efficiency.
