Refrigerator performance detecting method and temperature compensating method

Abstract

The invention discloses a refrigerator performance detecting method. A temperature data collector collects temperature information in a refrigerator and transmits the information to an industrial personal computer; a data processing system is arranged on the industrial personal computer and used for storing and displaying the temperature information; a signal transmitting and receiving device for wireless transmission, an input module capable of writing in parameter instructions, a comparator and a timer are arranged in the industrial personal computer and the data collector. The refrigerator performance detecting method comprises the following steps of: 1) setting an acceptable temperature value T in the input module; 2) reading and storing temperature Ta collected by the temperature data collector every t when the timer begins timing; and 3) reading the current temperature value Tb when the timer stops timing, and comparing Tb with T, if Tb is smaller than or identical to T, outputting a result that the performance is acceptable, and if Tb is greater than T, outputting a result that the performance is unacceptable. The method disclosed by the invention can be used for detecting a plurality of refrigerators at the same time, and a temperature compensating module can be used for exactly evaluating the performance of the refrigerators at different temperatures, so that the testing time of the refrigerators is reduced.

Description

technical field [0001] The invention relates to a refrigerator performance detection method and a temperature compensation method. Background technique [0002] Refrigeration is the core function of refrigerators, and the factory inspection of refrigeration performance is an indispensable link before refrigerator products enter the market. The ex-factory inspection procedure of the refrigeration performance of the existing refrigerator is that after the refrigerator enters the inspection line, temperature measurement points are arranged in the refrigerator, and the temperature measurement points are connected to the temperature data acquisition device outside the refrigerator. The temperature data of the temperature data acquisition device is taken, and the refrigeration performance is tested and judged according to the factory requirements. The current refrigerator temperature data acquisition device and the industrial computer are connected by wires. The industrial comput...

Problems solved by technology

Another disadvantage of this method is that the performance judgment and monitoring and testing process of the refrigerator need to be operated on-site on the testing line, and the testing equipment cannot be moved. Great inconvenience caused by human experimentation and research work

[0003] In addition, the current refrigerator performance testing requires placing the refrigerator at the standard ambient temperature for a period of time until the temperature in the box reaches the standard ambient temperature before starting the test, so as to evaluate the refrigeration effect of the refrigerator according to the established judgment criteria. It is necessary to build a special constant temperature laboratory, and to set up a constant temperature system in the laboratory requires a huge investment
