In the embodiment of the present application, fictitious load 11 is connected with frequency converter, and frequency converter can receive three-phase 380 volts and the alternating current of 50 hertz or 60 hertz.Then fixed-size for the frequency received alternating current is converted to the adjustable three-phase alternating current of frequency size.The three-phase alternating current that the frequency size that frequency converter provides is adjustable is for driving fictitious load, and then the performance of the compressor of simulation air-conditioning makes compressor operate when there being load, can detect at loaded situation down coversion driving force and compressor performance.
As shown in Figure 2, described function test method comprises:
S10: control described drive plate and produce the fixed-size three-phase alternating current of a frequency.
Specifically, in factory's air conditioner test process, for realizing the correct assessment to a certain performance parameter, needing to control the state of operation of air conditioner, and then ensureing that each air-conditioning operates under identical three-phase alternating current electric drive.
Specifically, when testing multiple air-conditioning, can control drive plate produce alternating current that a fixed-size three-phase alternating current of frequency makes the compressor of air-conditioning fix in testing process always drive under running, make testing result more accurate.
Next, perform step S20: obtain M first parameter value of M the first hardware under described three-phase alternating current electric drive be connected with described electrically-controlled component, M is positive integer.
Wherein, M can be 100 or 1000, and the application does not limit this.
Specifically, the first hardware can be: temperature sensor, four-way valve or blower fan.The first corresponding parameter value can be respectively: temperature sensor value, four-way valve output end voltage value or rotation speed of fan value.In specific implementation process, also can be the parameter of other hardware of air-conditioning, as: compressor exhaust temperature, suction temperature, discharge pressure, pressure of inspiration(Pi) etc.The application does not limit this.

Next, perform S30: judge whether described M the first parameter value meets predetermined condition for consistence, obtains judged result.
In the embodiment of the present application, can judge whether state M the first parameter value meets predetermined condition for consistence in the following way.
First, the standard parameter value of described first hardware under described three-phase alternating current electric drive is obtained.
Specifically, the standard parameter value of the first hardware under described three-phase alternating current electric drive can be obtained from the storage unit of system and the network equipment be connected with system.
In actual applications, standard parameter value is empirical parameter value or the ideal parameters value of first hardware of air-conditioning under this alternating current drives.
As: the ideal temperature value that temperature sensor detects is 25 degree, and the experience tachometer value of rotation speed of fan is 20 turns/s.
Then, M difference value of described M the first parameter value and described standard parameter value is obtained.
Specifically, M difference value is obtained according to the M obtained in step S20 the first parameter value and standard parameter value.
Next, based on a described M difference value, judge whether described M the first parameter value meets described condition for consistence, obtains judged result.
Specifically, the consistance of described M the first parameter value can be judged in several ways.In the embodiment of the present application, introduce following two kinds of modes.
First kind of way, obtains the difference of maximum different value in a described M difference value and minimum difference value;
Judge whether described difference is less than predetermined difference value threshold value, obtain judged result;
Wherein, when described judged result is for being, show that described M the first parameter value meets described condition for consistence.
Specifically, first kind of way is applicable to the situation that actual parameter value is distributed in actual parameter value both sides.According to maximum different value and minimum difference value, the difference determined, compares difference and difference threshold, and when difference is less than difference threshold, determine that M parameter value meets condition for consistence, namely the consistency of performance of the first hardware is better.
Wherein, difference threshold can be arranged according to actual needs, and the application does not limit this.
Such as: time higher for temperature sensor accuracy requirement, difference threshold can be set to 1 degree, and time lower for temperature sensor accuracy requirement, difference threshold can be set to 2 degree.
The second way, judges whether each difference value in a described M difference value is less than predetermined difference value threshold value, obtains M and judge sub-result; Judge sub-result based on described M, judge the consistance of described M the first parameter value, obtain judged result;
Wherein, when described M judges sub-result as being, described judged result shows that described M the first parameter value meets described condition for consistence.
Specifically, the second way is applicable to the distribution mode of any difference value, and when the first all parameter values is all less than difference value threshold value, determine that the first parameter value meets condition for consistence, namely the consistency of performance of the first hardware is better.
In the embodiment of the application, just two kinds of fairly simple modes are introduced, in actual applications, can according to other statistical distribution modes, as: normal distribution, judge the consistance of parameter, the application does not limit this.
Next, perform step S40: by described M the first parameter value and described judgment result displays on the display unit of described system, wherein, described judged result is for characterizing the consistance of the performance of described M the first hardware.
In actual applications, the first parameter value and judged result can be shown by display screen, in actual applications, can also export, so that tester checks parameters such as the parameter differences values of air-conditioning.
Next, for the blower fan of air-conditioning, illustrate and how to judge according to the consistency of performance of rotation speed of fan parameter to the blower fan of multiple air-conditioning of multiple air-conditioning, in specific implementation process, include but not limited to following example.
Supposing the system is tested the rotation speed of fan of 5 air-conditionings respectively, when the test signal that frequency converter provides is all the AC signal of 50Hz, the blower fan actual speed value of 5 air-conditionings is respectively: 20.3 turns/s, 20 turns/s, 19.7 turns/s, 19.4 turns/s, 22.1 turns/s, and when test signal is all the AC signal of 50Hz, the experience tachometer value (rated rotational frequency value) of air-conditioning draught fan is 22 turns/s, then obtains 5 difference value according to actual speed value and standard parameter value and be respectively: 0.3 turn/s, 0 turn/s,-0.3 turn/s ,-0.6 turn/s, 0.1 turn/s.
Suppose that adopting first kind of way whether to meet condition for consistence to 5 difference value judges.
First, difference between maximum different value 0.3 turn/s and minimum difference value-0.6 turn/s is 0.9 turn/s, suppose that difference threshold is 1 turn/s, because difference is less than difference threshold, then can determine that the blower fan actual speed value of these 5 air-conditionings meets condition for consistence, and then determine that the consistency of performance of blower fan of these 5 air-conditionings is better.
In the scheme of above-mentioned the embodiment of the present application, judged by the consistance of the hardware to air-conditioning, the prototype part that multiple air-conditioning adopts can be judged, as temperature sensor, blower fan, compressor etc., the conforming quality of performance, in conjunction with other parameters, as qualification rate etc., the more excellent components and parts of Bang Zu air-conditioning producer selectivity carry out air-conditioning production, to improve the quality of air-conditioning.
