MR055R Refrigeration Principle Training Equipment Educational Laboratory School Equipment Didactic Equipment Heat Colling Trainer I.Product Overview 1.1 Overview This course is a professional course for the major of Thermal Energy and Power Engineering. It aims to systematically introduce students to the principles of refrigeration and refrigeration equipment, so that students can master the composition, characteristics and thermodynamic calculation methods of various refrigeration cycles. It focuses on vapor compression refrigeration, and the principle part is mainly based on theoretical analysis. The equipment part focuses on the structure, characteristics and selection calculation of various refrigeration equipment, which also lays a foundation for students to further study other professional courses. 1.2 Features The training platform adopts an aluminum alloy chassis frame structure, which is simple and firm. While ensuring the overall strength of the equipment, the overall weight of the equipment is reduced. Protective feet are installed at the bottom. The equipment has a good safety protection system. The system power supply is controlled by a leakage circuit breaker to protect the compressor and system safety; the electrical control circuit is equipped with an emergency stop button and reliable grounding protection measures to ensure the safety of equipment and personnel.
