Refrigerator --r -conditioning m--ntenance and commissioning tr--ning desk,Portable pneumatic control tr--ning desk

The ZRLR-11A refrigerator --r-conditioning tr--ning assessment device "is based on the requirements of the Ministry of Education's" Revitalization of the 21st Century Vocational Education Course and Teaching Material Construction Plan ", with ability-oriented, employment-oriented, closely combined with the skills of production actual production and occupational positions. Products developed 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.

Tr--ning devices are also suitable for technical schools, vocational tr--ning schools, vocational education centers, appr--sal stations/institutions/institutions, refrigeration equipment "Refrigeration Equipment M--ntenance Industry (Primary, Intermediate, **)" Air conditioning device operation installation and m--ntenance "," small refrigeration device "," small refrigeration and --r -conditioning device "and other courses.

1. Features

1. The system integrates the simulation --r conditioner and simulation refrigerator, and adopts a real refrigeration unit to satisfy actual teaching

2. The device is equipped with 2 systems, 1 set of --r -conditioning systems, a direct -cold/cold refrigerator comprehensive system 1 set to meet the requirements of --r conditioning and refrigerator tr--ning operations at the same time

3. The whole set of tr--ning devices integrate --r conditioners, refrigerators, refrigerators, electrical control systems, and fault simulation systems. The system is true and complete, the structure is clear, and compact

4. 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. Digital display temperature meters, vacuum pressure gauges, and signal lights make the real -time working state of the entire heat pump split --r -conditioning system and refrigerator system clear at a glance; in addition, the pipeline has a visual liquid lens to observe the refrigerant state; The pipe is the blue part

5. The faulty setting can be simulated. Students analyze the causes of the f--lure of the f--lure, determine the scope of the f--lure, and perform the reasons. It is conducive to the skills appr--sal and assessment work
