Air -conditioning maintenance commissioning training device

"*r conditioning installation and commissioning tr--ning device" is a product developed in accordance with the requirements of the Ministry of Education's "Revitalizing the 21st Century Vocational Education Course Reform and Teaching Material Construction Plan", and develops 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 high vocational colleges and vocational schools and vocational schools, refrigeration fluid machinery, home refrigeration equipment, cold storage and refrigeration technology, refrigeration equipment rep--r engineers (junior, intermediate) tr--ning. 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/refrigeration majors "*r Conditioning Equipment", "Refrigeration Equipment M--ntenance Industry (Primary, Intermediate)", "Principles and M--ntenance of Home Refrigeration Equipment", "*r Conditioning Equipment", "Small Refrigeration and *r Conditioning Device" and other courses.

2. Overview of the device:

1. The tr--ning device visually shows the common tools required for --r conditioning debugging and installation, which is convenient for teaching demonstration explanations and students' understanding of textbook knowledge. Among them, the pipeline of the recycling unit is provided with a visual liquid lens to observe the refrigerant status; the high -pressure pipe road is red and the low -pressure pipe road is the blue part.

2. The whole set of tr--ning device integrates the refrigerant R22 recycling unit, the vacuum system unit, and the dual -group pressure controller unit. The entire system is truly complete, the structure is clear, compact, and meets the special tool tr--ning and operation requirements. Provide a good operating platform for --r conditioning installation and commissioning.

3. The system adopts a real refrigeration special tool tr--ning (compressor, wing tablet duct condenser, portable welding torch, cutting tube knife, expansion tube expansion, dual surface rep--r valve, public/English -made liquid pump, vacuum pump pump, vacuum pump, vacuum pump, vacuum pump, vacuum pump W--t), in line with actual teaching.

4. The tr--ning device provides students with an operating platform that allows students to complete tr--ning such as --r -conditioning system installation, commissioning, operation and m--ntenance.

5. The tr--ning system can complete the installation, commissioning, operation and m--ntenance of --r conditioners, which will help students apply theory to reality and cultivate students' actual operation ability.

Feature

1. The entire device is beautiful and generous, the structure is reasonable, the overall sense is strong, and has a strong engineering atmosphere, which can fully reflect the concept of modern laboratories.

2. The equipment is a self -propelled frame structure, and the feet are installed to facilitate the disassembly m--ntenance and handling of the system.

3. Except for special materials, the entire equipment is made of industrial 304 st--nless steel. All equipment is finely polished, which reflects the perfectness of the entire device.

4. This experimental device is a small industrial st--nless steel plate filter consisting of a filter plate and filter box, which can completely reflect the structure and operation process of the board frame filter machine. The --r is injected into the filter, and the concept of engineering is strong.

5. Filter plates adopt a flat thread -like mesh, advanced structure, easy to clean, and can effectively extend the service life of various filter membranes.

6. All sealing parts of the product are sealing ring with silicone rubber or fluorine rubber (acid -resistant alkali and alkali). High temperature resistance, corrosion resistance, non -toxic, leakless leakage, the equipment adopts a mechanical compression method, and the sealing performance is good.

7. Device design can be observed at 360 degrees to achieve comprehensive teaching and experiments.

6. The entire system adopts a standard industrial instrument control system, which can perform chemical principles experiments. It is also a good platform for process automation and chemical testing instrument experiments.
