Problems solved by technology
[0004] In order to solve the existing food freezer and refrigerator performance test due to the difference in test conditions, it is necessary to build two sets of performance test systems, which are used for the performance test of food freezer and refrigerator respectively. The purpose of this invention is to design a freezer and refrigerator. The performance test system can set two sets of supply and return air devices that meet different standards in the same test system, and realize the performance test requirements of different products through the automatic switching of the supply and return air electric dampers

Embodiment Construction
[0025] Such as figure 1 As shown, the embodiment discloses a structural schematic diagram of a performance test system for a freezer and a refrigerator that can satisfy horizontal and vertical air outlets. The multifunctional refrigerator performance test system is mainly composed of a test room, an air supply system, a return air system, an air handler 9, an air sampling device 15, and an electrical control part 16, etc.
[0026] The static pressure box 10 is the air outlet device. The air is processed by the air handler to a suitable temperature and humidity and then sent into the static pressure box 10. After being switched by the electric air valve, it enters the corresponding air supply channel, and is sent into the room horizontally or vertically through the orifice plate. , the unstable air flow enters the test room through the orifice plate and mixes evenly with the air in the test room, so as to obtain a uniform and stable temperature, humidity, and air velocity. The...

The invention discloses a performance testing system for a freezer and a refrigerator. The performance testing system comprises an air supplying system and an air returning system in a testing room, wherein the air supplying system comprises a static pressure box as an air outlet device, a horizontal air supplying device and a vertical air supplying device. The air returning system comprises a horizontal air returning device and a side air returning device. The static pressure box is connected with the horizontal air supplying device and the vertical air supplying device. The horizontal air supplying device is communicated with the horizontal air returning device for forming a horizontal air flow path. The vertical air supplying device can be connected with the side air returning device for forming a vertical air current path. The testing system can satisfy a requirement that the air supplying device and the air returning device in different standards are arranged in one testing system. Through automatic switching between an air supplying electric air valve and an air returning electric air valve, a performance testing requirement for the freezer and the refrigerator is satisfied.
Description
technical field [0001] The invention relates to an electrical performance test system, in particular to a freezer and refrigerator performance test system. Background technique [0002] The food freezer and refrigerator performance test system is used to test the storage temperature, freezing capacity, load temperature rise, power consumption, ice making capacity test, cooling capacity and other performance tests of food freezers and refrigerators. The test system simulates the actual temperature and humidity environment and airflow direction of food freezers and refrigerators, and conducts various performance tests on food freezers and refrigerators. The accuracy of the test data is determined by the closeness of the temperature and humidity environment and airflow direction provided by the test system to the actual use environment. [0003] Food freezers and refrigerators are used as refrigerating appliances. Different testing standards are implemented for performance tes...
