In principle, the high-voltage test is performed at the same connections as at the insulation-resistance test. In contrary to the insulation-resistance test, however, the high-voltage test is performed with much higher test voltages. The test voltage can be both AC and DC. When testing with AC, both the current of the ohmic insulation resistance and of the capacitive insulation resistance is detected.

a total current is calculated from the ohmic and the capacitive part. Especially at electric motors, this may sometimes effect, that a very high current is necessary for the high-voltage test. This high current is flowing, because the capacity of the test object is very high. As an alternative to testing with AC, it is also possible to test with DC.

This has the advantage that, similar to the insulation-resistance test, after a charging time of the capacitors, only the ohmic insulation resistance can be detected.

At the high-voltage test, the conducting test current must never be higher than a certain limit value. If this limit value is exceeded, the test voltage will be switched off immediately and automatically. It is also possible to pre-set a minimum current.

Especially in case of test objects, where a capacitive current is flowing at the high-voltage, it is possible to pre-set a minimum current. As soon as the minimum current is flowing, you can be sure that the test object is under high-voltage. This minimum current test is especially simple at the high-voltage test with AC.

However, the minimum-current test is also possible at the high-voltage test with DC. Upon switching on the high-voltage test DC, the capacity in the test object is charged for a short time.

This charging current impulse can be detected and serves as limit value pre-setting. Optionally we deliver testers with ARC detection. These input units may be, for example, an input unit or key board electrically connected to performance means The second test procedure means includes an automatic voltage regulator for restricting the changes of power voltage to generate static voltage and low voltage.

An automatic voltage regulator is a device for preventing damage to equipment by load due to the generation of overvoltage or low voltage, and for maintaining stability by way of constant voltage. Now, the operational effect of the performance test method of air conditioner thus constructed according to the present invention will be described.

Successively, at step S 2 , a worker manually manipulates the start switch of the first test procedure means to allow the performance discriminating means to discriminate whether a first test start signal is input, and if the first test start signal is not input that is, NO at step S 2 , the method repeatedly performs step S 2.

As a result of the discrimination at step S 2 , if the first test start signal is input YES at S 2 , flow of the method advances to step S 3 to start each test of the first test procedure means , where the gas detector at the first test procedure means detects the refrigerant gas of the outdoor unit 20 and the indoor RPM measurer measures the revolution rate of a motor in the indoor unit 10 to input the measured data to the performance discriminating means Successively, at step S 4 , the performance discriminating means compares the revolution rate of the motor of indoor unit 10 measured by the indoor RPM measurer with the established revolutions per minute of test set identified by bar code to discriminate whether the revolution rate of the motor in the indoor unit 10 is within the allowable range, and if the revolution rate is not within the allowable range NO at S 41 , flow of the method advances to step S 41 , where the performance discriminating means discriminates that the revolution rate of the motor in the indoor unit 10 is bad and causes the display means to indicate that the revolution rate of the motor in the indoor unit 10 is bad, thereby terminating the operation discharge of the set.

Meanwhile, as a result of the discrimination at step S 5 , if the gas leakage switch is not turned on that is, NO at step S 5 , flow of the method proceeds to step S 6 to allow a worker to check an operational status of the indoor unit 10 fan, louver, lamp, buzzer, etc and performance discriminating means discriminates whether the operation switch is manually turned on.

As a result of the discrimination at step S 6 , if the operation switch is turned on YES at step S 6 , flow of the method advances to step S 61 , where the performance discriminating means discriminates that the indoor unit 10 is inoperable and causes the display means to indicate that the indoor unit 10 is inoperable and to terminate the operation.

Meanwhile, as a result of the discrimination at step S 6 , if the operation switch is not turned on NO at step S 6 , flow of the method proceeds to step S 7 , where a worker checks noise state of the indoor unit 10 to decide whether to manually operate the abnormal room noise switch As a result of the discrimination at step S 7 , if the abnormal room noise switch is turned on YES in step S 7 , flow of the method proceeds to step S 71 , where the performance discriminating means discriminates that the indoor unit 10 is bad in terms of noise state and thereby causes the display means to indicate that the indoor unit 10 is bad in noise state, and terminates the operation.

Meanwhile, as a result of the discrimination at step S 7 , if the abnormal room noise switch is not turned on in case of NO , flow of the method advances to step S 8 , where a worker manually manipulates the end switch of the first test procedure means to determine whether a first test end signal is input to the performance discriminating means , and if the signal is not input that is, in case of NO , step S 8 is repeated.

As a result of the discrimination at step S 8 , if the first test end signal is input in case of YES , flow of the method advances to step S 9 because each test at the first test procedure means has been sequentially progressed through and completed.

At step S 9 a worker connects a communication cable between the indoor unit 10 put into the second test procedure means and the outdoor unit Flow of the method now advances to step S 10 where a pipe is connected between the outdoor unit 20 and the dummy indoor unit Successively, at step S 11 , a worker decides whether to manually turn on the start switch of the second test procedure means and performance discriminating means discriminates whether a second test start signal has been input, and if the second test start signal is not input NO in S 11 , step S 11 is repeated.

As a result of discrimination at step S 11 , if the second test start signal is input YES in step S 11 , flow of the method proceeds to step S 12 because each test of the second test procedure means should be started, where the tester at the second test procedure means tests voltage resistance, insulation resistance, earthing resistance to input the test values to the performance discriminating means Successively, at step S 13 , the performance discriminating means compares the voltage resistance, insulation resistance and earthing resistance detected by the tester with the voltage resistance, insulation resistance and earthing resistance set-up value identified by the bar code to discriminate whether the voltage resistance, insulation resistance and earthing resistance are within the allowable limit.

As a result of the discrimination at step S 13 , if the voltage resistance, insulation resistance and earthing resistance are not in the allowable range NO in step S 13 , flow of the method proceeds to step S , where the performance discriminating means discriminates that the voltage resistance, insulation resistance and earthing resistance are bad to allow the display means to indicate that the voltage resistance, insulation resistance and earthing resistance are bad, thereby terminating the operation.

Meanwhile, as a result of the discrimination at step S 13 , if the voltage resistance, insulation resistance and earthing resistances are good YES at step S 13 , flow of the method advances to step S 14 , where the worker discriminates whether the cooling remote controller is manually turned on, and if the heating remote controller is not turned on in case of NO , step S 14 is repeatedly performed.

As a result of the discrimination at step S 14 , if the heating remote controller is turned on in case of YES , flow of the method proceeds to step S 15 , where the performance discriminating means tests a low voltage generated from the automatic voltage regulator at the second test procedure means during the heating operation.

Successively, at step S 16 , the performance discriminating means compares the tested low voltage with the low voltage set-up value analyzed by the bar code to discriminate whether the low voltage is within the allowable limit.

If the low voltage is not within the allowable range in case of NO , flow of the method advances to step S , where the performance discriminating means discriminates that the low voltage is bad to cause the display means to indicate that the low voltage is bad, thereby terminating operation.

As a result of the discrimination at step S 16 , if the low voltage is within the allowable range YES at step S 16 , flow of the method proceeds to step S 17 , where the worker discriminates whether the cooling remote controller is manually turned on, and if the cooling remote controller is not turned on in case of NO , step S 17 is repeatedly performed.

As a result of discrimination at step S 17 , if the cooling remote controller is turned on in case of YES , flow of the method proceeds to step S 18 , where the performance discriminating means performs a normal cooling operation.

At this time, at step S 19 , the outdoor RPM measurer of the second test procedure means measures the revolutions per minute of the motor in the outdoor unit 20 , and the power meter measures consumed power, while the temperature recorder measures a temperature difference between inlet and outlet of the dummy indoor unit disposed in the second test procedure means to record same.

Successively, at step S 20 , the performance discriminating means compares the consumed power measured by the power meter with consumed power set-up value recorded for this bar code value, while the temperature recorder compares the temperature difference between inlet and outlet of the dummy indoor unit measured by the temperature recorder with the temperature difference set-up value recorded for this bar code value, to discriminate whether the cooling electricity characteristic is within an allowable range.

As a result of the discrimination at step S 20 , if the cooling electricity characteristic is not within the allowable range in case of NO , flow of the method proceeds to step S , where the performance discriminating means discriminates that cooling is bad to cause the display means to indicate that the cooling is bad and to stop operation.

Meanwhile, as a result of the discrimination at step S 20 , if the cooling electricity characteristic is within the allowable range in case of YES , flow of the method advances to step S 21 , where the worker checks the heating status to discriminate whether the bad heating switch is manually turned on.

As a result of the discrimination at step S 21 , if the bad heating switch is turned on YES at step S 21 , flow of the method proceeds to step S , where the performance discriminating means discriminates that the heating is bad to cause the display means to indicate that the heating is bad and to terminate the operation.

As a result of discrimination at step S 21 , if the bad heating switch is not turned on NO at step S 21 , flow of the method proceeds to step S 22 , where the worker checks the noise status of the outdoor unit 20 to determine whether to manually turn on the abnormal outdoor noise switch As a result of the discrimination at step S 22 , if the abnormal outdoor noise switch is turned on YES in step S 22 , flow of the method proceeds to step S , where the performance discriminating means discriminates that the noise status of the outdoor unit 20 is bad to cause the display means to indicate that the noise of the outdoor unit is bad and to terminate the operation.

Meanwhile, as a result of the discrimination at step S 22 , if the abnormal outdoor noise switch is not turned on NO at step S 22 , flow of the method advances to step S 23 , where the worker checks the communication between the indoor unit 10 and the outdoor unit 20 to thereafter determine whether to manually turn on communication switch As a result of the discrimination at step S 23 , if the bad communication switch is turned on YES at step S 23 , flow of the method proceeds to step S , where the performance discriminating means discriminates that the communication is bad to cause the display means to indicate that the communication is bad and to thereafter terminate the operation.

Meanwhile, as a result of the discrimination at step S 23 , if the bad communication switch is not turned on NO at S 23 , flow of the method advances to step S 24 , where the worker manually manipulates the end switch at the second test procedure means to determine whether second test end signal is input to the performance discriminating means , and if the signal is not input NO at S 24 , step S 24 is repeatedly performed.

As a result of the discrimination at step S 24 , if the second test end signal is input YES at S 24 , flow of the method advances to step S 25 because each test at the second test procedure means has been sequentially processed and completed.

Meanwhile, although the preferred embodiment of the present invention has been described with reference to sequential progress of each test at the first test procedure means and the second test procedure means , the present invention is not intended to be restricted to the above embodiment disclosed, which is considered to be purely exemplary.

It should be understood that the production line for simultaneously assembling the indoor units 10 and the outdoor units 20 can include other test procedures for testing performances of the indoor units 10 and the outdoor units 20 in addition to the first and second test procedure means , As apparent from the foregoing, there is an advantage in the performance testing method of air conditioner thus described according to the present invention in that a production line for simultaneously assembling indoor units and outdoor units and simultaneously testing same performs the testing of the indoor units and outdoor units at the same time, thereby shortening the working hours.
