2. Basic structure

Experimental desk: Crossing the rack module, institutional component module, workbench module, standard parts module, work volume module, etc. Experimental tables and racks are processed by high -quality cold steel plates through sheet metal. The m--n parts are hung on the shelf, and 1 10 -inch tablet display is placed on the workbench, which can display the disassembly process and usage method of the operation of the operation.

3. M--n functions

It is m--nly used for mechanical principles and mechanical innovation design and other courses. Innovation innovation and their assembly and simulation experiments, through the assembly of physical institutions, deepen the understanding of the principles and movement characteristics of the institution, determine the type of coordination of the holes and shafts, and choose the processing accuracy. During the map of the surveying and mapping parts, the picture is assembled, the processing process is prepared, the assembly process is prepared, and the comprehensive design ability of the student institutions and the ability of engineering practice can be cultivated. The accessories provided by the experimental table can complete the assembly experiment of no less than 32 institutional motion solutions.

The equipment is a product of research and development in accordance with the requirements of the Ministry of Education's "Revitalizing the 21st Century Vocational Education Curriculum Reform and Teaching Material Construction Plan", in accordance with the teaching and tr--ning requirements of vocational education. It is suitable for teaching tr--ning devices such as refrigeration technology such as refrigeration, refrigeration equipment and m--ntenance, cold storage and refrigerated technology, refrigeration equipment (junior, intermediate, and **) tr--ning devices such as higher vocational colleges and vocational schools. Cultivate the theoretical knowledge and professional practical skills of --r conditioning and refrigeration technology, and engage in technical upgrades, renovation design, installation, commissioning, m--ntenance, m--ntenance, technical management and other aspects of technical upgrades, renovation design, installation, commissioning, m--ntenance, m--ntenance, and technical management of --r conditioning, refrigeration equipment and systems.

Home split --r -conditioning skills tr--ning assessment desk is also suitable for technical schools, vocational tr--ning schools, vocational education centers, appr--sal stations/refrigeration majors "Refrigeration Equipment M--ntenance Industry (Primary, Intermediate, **)" M--ntenance "," Refrigeration *r Conditioner Device Operation and Installation and M--ntenance "," Small Refrigeration Device "," Small Refrigeration and *r Conditioning Device "and other courses.

1. Device characteristics

1. The tr--ning device visually shows the system structure and working principle of the heat pump type --r conditioner. It can be clearly seen that the real objects of the refrigeration circulation system structure and the m--n components. The pressure gauge, signal lights, and luminous diode make the real -time working state of the entire split --r -conditioning system at a glance; the m--n panel has a control system schematic in the middle of the m--n panel and has corresponding test points; it is convenient for teaching demonstration explanations and students' understanding of textbook knowledge. In addition, the pipeline has a visual liquid lens to observe the condition of the refrigerant; the high -pressure tube road is red and the low -pressure pipe road is the blue part. The corresponding parts have the name logo

2. The system adopts a real 1 -refrigeration unit, which is in line with actual teaching. The entire --r -conditioning system is true and complete, which is exactly the same as the overall structure and performance of the remote control heat pump --r conditioner on the market. It has functions such as cooling, heating, ventilation, dehumidification, temperature, wind speed selection, timing, wind sweeping control, sleep, automatic sleep, automatic sleep, automatic sleep, automatic sleep, automatic sleep, automatic sleep

3. The whole set of tr--ning device integrates the refrigeration system, electrical control system, and the fault simulation system. The system is true and complete, and the structure is clear and compact. It is consistent with the actual --r -conditioning refrigeration system and electrical system to meet the requirements of tr--ning tr--ning.

4. It can simulate the fault setting. Students analyze the cause of the f--lure of the process, determine the scope of the f--lure, and perform reasons. It is conducive to the skills appr--sal and assessment work

5. The device has the electrical control line wiring area of the outdoor unit component, which can complete the judgment of electrical connection, compressor winding, etc., which is conducive to students applying theory to reality and cultivating students' actual operation ability.
