Abstract

The article provides the prerequisites for creating a method for assessing the technical condition of a small refrigeration machine using a programmable controller, as well as a description of a programmable controller algorithm that allows monitoring the current performance of the small refrigeration machine in more detail, based on the existing method for detecting changes in the specific energy consumption of a small refrigeration machine by measuring the performance of a small refrigeration machine before its operation and after it is regulated Foot period of its operation. An important point in this approach to assessing the technical condition of a small refrigeration machine is the procedure for creating identical measurement conditions before and after the period of operation. For example, it is necessary to obtain data for comparison at the same ambient temperature. The article draws conclusions and recommendations on creating a programmable controller with a given algorithm for assessing the technical condition of a small refrigeration machine.
