Whether cooling in summer or heating in winter, the performance of the air conditioner brings great influence to users. Especially, winter heat pump air conditioner heating effect is not good enough, and the air conditioner generally has auxiliary electric heating function in order to promote better use experience. The auxiliary electric heating has various types such as an electric heating wire type electric heating tube, a ceramic PTC type semiconductor heater, and the like. Under the condition of unchanged voltage, wind speed and temperature, the electric heating wire type auxiliary electric heating power is constant, and the PTC type auxiliary electric heating is higher in power (1.5-3 times of rated power) when started and is reduced to the rated power after about 30 seconds. The auxiliary electric heating is used as a heating device, so that heating and firing safety accidents are easy to occur, and the safety requirement is very high. When the air conditioner controller does not start the electric heating function, the auxiliary electric heating cannot work; when the electric heating function is started, the auxiliary electric heating power should be within the rated value range.
Therefore, in the inspection of an air conditioner before shipment, the test of the performance of auxiliary electric heating is one of the important inspection items. However, the auxiliary electric heating assembly is matched with the control system on the whole machine for testing, the testing efficiency is low, and a plurality of test items need to be strictly tested.

The system comprises: the first control board sends an instruction for starting the electric heating pipe; the second control board is connected with the first control board, receives an instruction for starting the electric heating pipe sent by the first control board, and controls the electric heating pipe to be started according to the control instruction; the first testing device is connected with the first control board, acquires state parameters of the electric heating pipe in an on state, and transmits the acquired state parameters to the upper computer; the upper computer is connected with the first testing device, generates a testing instruction, and sends the testing instruction to the first control board so that the first control board sends an instruction for starting the electric heating pipe, receives the state parameter transmitted by the first testing device, and generates an instruction for abnormal state of the electric heating pipe when the state parameter is not matched with the preset state parameter. The ceramic PTC heater has great power variation in different working stages, the method does not carry out detailed test in stages, and the test result is inaccurate. When in online test, the power values of a plurality of air conditioners are read when the method cannot avoid the problem, so that the test result is disordered. During online testing, the station is empty, and the detection efficiency is reduced.

The conveying device 3 is used for carrying and conveying the air conditioner 1. At least one detection zone is provided along the transfer device 3.

The processing device 44 receives the device information, receives the power information, and analyzes and processes the power information to obtain a test result.
The air conditioner 1 is placed on the conveying equipment 3, in the conveying process, the power of the electric heating air conditioner 1 with specified time can be tested, and the power is tested along with the change of the time of the electric heating, so that the aim of testing the performance of the auxiliary electric heating of the air conditioner 1 is fulfilled. The test result is processed by the processing device 4 and then is output, so that the automatic test operation of auxiliary electric heating of the air conditioner 1 is realized. The accuracy of the test result is improved, the problem of disordered test results caused by simultaneous testing of a plurality of air conditioners 1 is avoided, and the detection efficiency is improved.
Specifically, the conveying equipment comprises a power device, a conveying belt and a controller. The conveyor belt is connected with the power device for bearing and conveying the air conditioner 1. And the controller is connected with the power device and used for controlling the speed of the conveyor belt.
When the air conditioner 1 is tested, the air conditioner is conveyed to a test end point L2 along a conveying direction I from a test start point L1 through a conveying belt, and after the test time is determined through the processing device 44, the running speed of the conveying belt driven by the power equipment is controlled through the controller. In the test process, only one air conditioner 1 is tested on the conveyor belt, and the running speed of the conveyor belt is controlled by the controller to be improved as much as possible on the basis of the test time determined by the processing device 44, so that the test efficiency is improved.
As an example, as shown in fig. 4, the heating wire type electric heating tube is constant in resistance and constant in power, and the time required for the test is short (t 4-t0 is about 20 s). As shown in fig. 5, the ceramic PTC type semiconductor heater has its power increased to 1.5-3 times rated power at the moment of energization, and thereafter slowly decreased to a steady state value.

Further, as shown in fig. 2, the power supply apparatus 2 includes a variable frequency power supply (not shown), a conductive plate assembly, and a connector 21. The conducting plate assembly is arranged below the conveyor belt corresponding to the detection area and is electrically connected with the variable-frequency power supply. A connector 21 is provided above the conveyor belt and electrically connected to the conductive plate assembly and the air conditioner 1.
With the above-described structure, the air conditioner 1 turns on the power supply device 2. At the same time, the power supply device supplies power to the transfer device 3 and the detection device 4.
Further, the power supply device further includes a conductive spring piece 24, and the connector 21 is electrically connected with the conductive board assembly through the conductive spring piece 24. When the conveyor belt carries the air conditioner 1 to the outside of the detection area, the conductive spring piece 24 is separated from the conductive plate assembly. When the conveyor belt carries the air conditioner to move to the detection area, the conductive spring piece 24 is in contact connection with the conductive plate assembly.
When the air conditioner 1 is placed on the conveyor belt through the conductive elastic sheet 24, the conductive elastic sheet 24 is pressed down through the weight of the air conditioner 1 to be connected with the conductive plate assembly, so that the air conditioner 1 is automatically connected with the power supply equipment.
