Abstract
The present invention relates to an on-line testing facility of a refrigerator refrigerating performance item and the determination of an equivalent testing method thereof. The equivalent testing method is realized by using the following three aspects: (1), the on-line testing facility uses a heat insulation testing channel (2) as a main body; (2), a method of the on-line testing facility implements the refrigerator (4) refrigerating performance testing item and uses a preparation stage and a testing stage as main bodies; (3), a method for determining an equivalent relation which is established by related testing data of the refrigerating performance testing item and a Chinese standard requirement. When each volume-produced refrigerator (4) carries out a test which relates to the refrigerating performance item (cooling rate), the refrigerator refrigerating performance item on-line testing facility creates conditions for the high-speed on-line test of the refrigerator (4). Meanwhile, because the testing environment volume of the on-line testing channel (2) is very small, the refrigerator refrigerating performance item on-line testing facility creates conditions for increasing the testing precision (the wind speed can be controlled into very small, and the temperature distribution is even) of heating quality testing items.
