Problems solved by technology
In this way, there are several problems: a. The new refrigeration system solution needs to be re-produced; b. The refrigerator installed with the new refrigeration system solution also needs to be produced. If it is a new product development, it needs to wait for the development of other parts of the refrigerator to be completed and the mold is opened. c. If there are different types of refrigerators, it is necessary to produce different refrigerators for testing
However, the traditional refrigerator system test bench is a single-station single machine test, and the test time is long, and the test results need to be compared manually. When comparing two refrigeration systems, it is necessary to produce two sets of prototypes in advance (refrigerator box body) Prototype, and the refrigeration system with the refrigerator box installed), and then set the same various parameters, and compare the results of each refrigeration system to be tested one by one. The experiment takes a long time and the operation is cumbersome

Embodiment Construction
[0020] Referring to the accompanying drawings, specific embodiments of the present invention will be described below.
[0021] see Figure 2-Figure 4 , one aspect of the present invention provides a kind of refrigeration system testing equipment, and it comprises: box body (test sealing box), main controller, the heater that is arranged in box body, the temperature sensor that is located in box body, wherein heater and temperature sensor are respectively electrically connected to the heater. The box has a heat-insulated sealed space, which is cooled by the refrigeration system to be tested; the main controller adjusts the heating power of the heater according to the temperature of the sealed space detected by the temperature sensor, so as to simulate the sealed space as a box with a specified refrigeration equipment internal temperature environment. In order to achieve a good heat insulation effect in the sealed space of the box, the box can be configured to have stainless s...

The invention provides a refrigeration system testing device, comprising: a box body with a thermally insulated sealed space, and the sealed space is cooled by the refrigeration system to be tested; a heater is arranged in the sealed space; a main controller is connected with the sealed space The above-mentioned heater is electrically connected, and the main controller adjusts the heating power of the heater to simulate the sealed space as having a specified temperature environment in the refrigeration equipment box. A method for shortening the test time of the refrigeration system is also provided. The test equipment of the present invention is used to test the refrigeration system, and during the test: when the temperature of the sealed space of the test equipment drops to a first predetermined value, the heating power of the heater is increased Until the temperature rises to the second predetermined value, then reduce the heating power to the initial value. The invention can test different refrigeration systems without producing new refrigeration equipment box prototypes.
Description
technical field [0001] The invention relates to a refrigeration system test device and a method for shortening the test time of the refrigeration system. Background technique [0002] Now all refrigerators are installed in actual refrigerators after the prototypes of new refrigeration system solutions are produced during the development and testing process, and then tested in the laboratory. In this way, there are several problems: a. The new refrigeration system solution needs to be re-produced; b. The refrigerator installed with the new refrigeration system solution also needs to be produced. If it is a new product development, it needs to wait for the development of other parts of the refrigerator to be completed and the mold is opened. c. If there are different types of refrigerators, different refrigerators need to be produced for testing. d. The test products will be scrapped in the end. In this way, the development of the refrigeration system is restricted by the ov...
