1. Product Overview This training device is used to study refrigeration compression cycle and evaporation system. The compressor drives the refrigerant to carry out the refrigeration cycle, introduces the operation mode of the refrigeration circuit to the students systematically, masters the principle of the refrigeration circuit and the operation mode of the compressor, and displays the system, so that the students can clearly understand the principle in the teaching process. Master the refrigeration principle and piping connection principle of the refrigeration circuit. 2. Equipment Features The training platform adopts a sheet metal welded frame structure, which is simple and firm in structure. It reduces the overall weight of the equipment while ensuring the overall strength of the equipment. There are 4 universal wheels installed at the bottom, which can be easily moved. The refrigeration cycle pipeline is laid on the equipment installation board, and the high and low temperature areas are painted with different colors for easy observation and distinction. The equipment has a good security protection system. The compressor is equipped with a start-up protector, which can immediately stop the compressor when the system pressure is abnormal to protect the compressor and system safety; The electrical control is installed in the control box with leakage protection switch, emergency stop button and reliable grounding protection measures to ensure equipment and personal safety. 3.
