Using MT 210, students can develop skills on how to undertake a complex engineering project. In the course of the exercise they independently develop an appreciation for the fundamentals and correlations involved, and then contribute to the overall outcome using teamwork. The skills developed are the planning, execution and checking of assembly; commissioning, and maintenance operations. The assembly process includes a mechanical element (frame, sheet plates, front panel), a refrigeration element (condenser set, evaporator, expansion valve, piping etc.) and the electrical and process control element (electrical wiring of the complete system as per the circuit diagram; thermostat; pressure switch). The tool set ET 150.02 is required to assemble the unit. The ET 150.01 refrigeration charging and evacuation station is required for commissioning (including testing of the electrical system and leak testing of the refrigeration circuit). The fully assembled MT 210 presents a real, fully functional temperature-controlled cooling system with cooling chamber and electric thermostat. The system is supplied in kit form. |
