Development of a mobile device for collection of heat power parameters of the refrigerator

To reduce the amount of time required for the acceptance testing of the refrigerator, it was necessary to develop the system described in this article, which would reduce the test time for each refrigerator to 6–9 minutes. The article describes what this system consists of, separately describes each piece of equipment and its role in the system as a whole, the method of connecting all devices into a single installation, the communication protocol, the method of cloud storage of data for the ability to access them from any mobile device. The principle of operation of the installation is to measure the temperature at certain points of the condenser of the refrigerator when it is connected to the power supply. Analysis of the heat and power properties of the refrigerator in conjunction with the analysis of the cooling rate of the refrigerating chambers (as well as the heating of the condenser) makes it possible to understand whether each refrigerator corresponds to certain characteristics established by GOST. Also in the article you can get acquainted with the characteristics of the devices used (TPM 138 temperature meter-regulator, module for measuring parameters of the electrical network ME110-224-1M).
