Temperature compensation method for detecting performances

Abstract

The invention discloses a temperature compensation method for detecting performances. The temperature compensation method includes acquiring and transmitting information to an industrial computer by a temperature data acquirer, storing and displaying the temperature information in a fixed format by a data processing system, setting an optimal ambient temperature value T1 and a temperature difference correspondence table including different differential intervals and corresponding compensation values, reading the ambient temperature Tx and actuating a temperature compensation subprogram when the Tx is unequal to T1; computing according to the equation of Tx-T1=A; comparing the A with the temperature difference correspondence table and obtaining a corresponding compensation value B; setting a qualified temperature value T in an input module, reading and storing temperature values Ta acquired by the temperature data acquirer at each interval t after a timer starts timing, and reading a current temperature value Tb when the timer stops timing; outputting a qualified result if Tb+B is smaller than or equal to the T; and outputting a disqualified result of Tb+B is larger than the T. by the aid of the temperature compensation method, the performances of a refrigerator at different ambient temperatures can be accurately evaluated, and refrigerator testing time is shortened.

Description

technical field [0001] The invention relates to a temperature compensation method for performance detection. 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 computer and the temperature...

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
