Problems solved by technology

[0003] Luxurious and high-end refrigerators often have some functions such as automatic frosting, temperature compensation, and room temperature change. These functions are mainly realized by electric heaters, electric dampers, solenoid valves and other devices. Relying on manual judgment of refrigerator performance is very error-prone

Embodiment Construction

[0019] In this embodiment, the refrigeration performance dynamic test system of the refrigerator is to run the lower computer and test tooling of the test system on the assembly line together with the refrigerator under test, and the collector simultaneously collects the set parameters to obtain test data, and transmits the test data through wireless transmission. The test data is sent to the upper computer, and the upper computer analyzes the test data according to the set process plan, and then judges the performance of the refrigerator.

[0020] Selection of refrigerator test location: At present, household refrigerators use vapor compression refrigeration. When the refrigerator is running stably, the refrigerant is in a state of saturated steam in the evaporator, which absorbs "latent heat". no big difference. When the refrigerator is blocked or the refrigerant leaks, the end of the evaporator will be in an "overheated" state, and the temperature at the end of the evaporat...

Abstract

The invention discloses a dynamic refrigerator refrigeration performance testing system. The dynamic refrigerator refrigeration performance testing system is characterized in that a lower computer and a testing tool of the testing system and a refrigerator to be tested move on a production line together, a collector simultaneously collects setup parameters so as to obtain test data, the test data are sent to an upper computer in a wireless transmission manner, and the upper computer analyzes the test data according to a set technological program so as to judge the performance of the refrigerator. As adopting a multi-condition comprehensive judgment model, the testing system can judge the performance of the refrigerator more exactly, and is better adaptive to product performance tests of different refrigerators.

Description

technical field [0001] The invention relates to the field of refrigerator manufacturing, in particular to a dynamic test system for refrigerator refrigeration performance. technical background [0002] The traditional refrigerator performance test line is a static test, that is, the test tool is fixed, the refrigerator is transported to each test station by the assembly line, and the refrigerator of a test line is "full" before it can be energized and run to start the test. This way wastes a lot of time and production space. The traditional refrigeration performance testing process of refrigerators is to arrange temperature probe points in each temperature zone of the refrigerator, and mainly rely on manual methods to count the number of starts and stops within the test time and the approximate range of the temperature in the box, and use this to identify the performance of the refrigerator. good or bad. [0003] Luxurious and high-end refrigerators often have some functio...
