Development and Teaching Application of a Performance Test Bench for Refrigerant Compressors

To better integrate theoretical knowledge with engineering practice, a comprehensive practical teaching project, the “Refrigerant Compressor Performance Experiment”, was established for energy and power engineering students. A compressor performance test bench based on the second refrigerant calorimeter method and refrigerant liquid flow meter method was developed in accordance with national standards. The experimental teaching content was designed and the key teaching points were explored. This experimental project enables students to understand the principles and methods of refrigerant compressor performance testing, master the regulation and control of refrigeration systems, thereby strengthening their engineering thinking and enhancing their ability to solve engineering problems.
