Test method for evaluating evaporation capacity of water pan of refrigerator

Abstract

The invention discloses a test method for evaluating the evaporation capacity of a water pan of a refrigerator, and relates to the technical field of refrigerators. The method comprises the following steps: (1) putting a to-be-tested refrigerator into a standard environment laboratory, and setting an environment temperature condition of the environment laboratory; (2) powering on the refrigerator, setting the temperature of a refrigerator chamber, and placing a test load in the refrigerator chamber; (3) arranging a door opening and closing tester and a test recorder thereof, and setting door opening and closing times. (4) starting a refrigerator test recorder, detecting the water volume of a water pan of the refrigerator according to the running state of the refrigerator, recording corresponding data, repeating the test twice, and recording the data information of the water volume of the water pan twice; (5) analyzing and calculating the evaporation capacity index of the water pan according to the recorded water volume of the water pan; and (6) carrying out risk evaluation on the evaporation capacity index of the water receiving disc. According to the method, the evaporation speed characteristic of the defrosting water in the receiving tray of the refrigerator is efficiently and accurately obtained, the evaporation capacity index of the water receiving tray is obtained, and the defrosting water evaporation capacity of the water receiving tray is accurately reflected.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, in particular to a test method for evaluating the evaporation capacity of a refrigerator water tray. Background technique [0002] The existing frost-free refrigerator adopts the forced convection heat exchange method of the evaporator. During the cooling process, the evaporator exchanges heat with the indoor air in the refrigerator. The cooling deposits on the surface of the evaporator to form frost. [0003] When the surface of the evaporator grows with frost, the cooling effect gradually deteriorates, and the energy consumption of the refrigerator increases. When the frost layer grows to affect the air circulation, it will seriously affect the normal refrigeration of the refrigerator. Therefore, the frost-free refrigerator needs to be defrosted regularly. The water generated on the evaporator passes through the defrosting drainage system, and finally leads the defrosting water to the wa...

Problems solved by technology

[0007] In terms of existing test methods, the internal inspection methods developed by various refrigerator manufacturers can only test the water storage capacity of the water tray within a certain period of time, and cannot evaluate the evaporation capacity of the defrosting water of the refrigerator water tray through this test method , the test method has a certain one-sidedness, so it is necessary to establish a test method for evaluating the evaporation capacity of defrosting water in the refrigerator water tray
