Refrigerator Performance Testing System

1． System summarize

 The refrigerator cooling testing system that developed by us uses network structure and digital communication technique to ensure veracity of data transmit and improve system ability of expanding and maintenance. It is a good replacing system for current simulation testing system and it shows hearty life-force. We are winners to compete with others in public bidding of project and getting a good reputation. Example as BSH cooling appliances co., ltd.,  Haier group, Meiling group, Xinfei corporation and so on.

 The system can test many performance parameters of refrigerator, such as temperatures, input power, power consumption, power factor, working status of electromagnetism valve and so on. It is a general system, it can test cooling speed as well as long time aging-test (simulation using condition), and then it can test some items of standard testing for refrigerator.

 Our designers know well manufacture technique and characteristic of refrigerator. They have plenty of experience for testing and designing.

2． System request

 According to Specification of Cooling Testing System, there are 5 pcs testing lines and there are 42 pcs testing points for each testing line, total 210 pcs testing points. Temperature of freezer and cooler should be tested for each testing point.

3． System composing

3.1   The system bases on 485 bus, using 1 set computer to manage 5 pcs testing lines.

3.2    It will be set up with 1 pcs long-distance temperature module and 2 pcs temperature sensors for each testing point.  All of the modules can transfer real time tested data to computer, the data is managed by the computer and can be printed out at any time.       

3.3    It will be set up with 1 set barcode scanner to transfer information of product model to computer in the testing system.

3.4    It will be set up with1 set laser printer to print report forms and curve of tested data. 

3.5    It will be set up with 1 pcs environment temperature module and 1 pcs temperature sensor to   test environment temperature of each testing line.

3.6    All modules and temperature sensors of the system will be fixed in Specific cable channel, its model is 100*75

4． System parameter

4.1  Testing temperature range: –50℃~+80℃, testing accuracy: ±0.5℃, minimum unit:0.1℃

4.2  Power supply :AC220V/50Hz±10%

4.3  Environment temperature for testing system: 5~50℃,humidity: <90%

5． System function

5.1  The system collects real time temperature data from each testing point. 

5.2  Computer manages these data sent from each testing point and displays it. And can print the data at any moment.

5.3  Testing periods and collection periods could be set up.

5.4  System has diagnosing function for failure at the same time displays the code of failure and No. of testing point .

5.5  System has self-calibrating function for testing parameters comparing to the standard parameters.

5.6  System sets one sensor to detect the temperature of Environment and displays it in the system. 

5.7  Performance curves of random 6 refrigerators can be displayed in one chart for easy  comparison among them.

5.8  In chart area, The system can display parameter value of temperature for every points when  moving mouse to the point and single-clicking it.

5.9  Tested data is saved in the system with database, it is very easy for querying and statistics.
