The device integrates refrigeration and air conditioning system installation, refrigerator system installation, refrigeration system electrical wiring, pressure leak detection, vacuuming, refrigerant charging, and operation debugging. It includes all the steps of refrigeration system maintenance and can meet practical training and teaching. , The needs of actual engineering training and vocational skill competition.
  2. The device adopts a modular design, the electrical control and the refrigeration system are separated independently, and the electrical part is equipped with detection points, test terminals and various output connection terminals, which can be used for independent wiring, testing, and remote travel operations.
  3. The training platform visually demonstrates the system structure and working principle of air conditioners and refrigerators. The structure of the refrigeration system and the main components can be clearly seen. The system is also equipped with a voltmeter, AC ammeter, pressure gauge, signal indicator, etc., so that the real-time working status of the entire air conditioning system and refrigerator system can be seen at a glance.
  4. The device is based on the split air conditioner control circuit and refrigerator electronic control circuit as the training and assessment objects, which can enable students to master the basic principles and maintenance techniques of the air conditioner control circuit, refrigerator electronic control circuit, and the assessment board Printed with split-type air conditioner electrical and refrigerator electronic control circuit diagrams and check points. Students understand the principle through the circuit diagram on the assessment board, and set up the fault through the computer, and use the instrument to detect the fault location on the check point and eliminate it. Failure, thereby improving students' ability to troubleshoot.
  5. Use this device to learn the relevant knowledge of split type air conditioner control circuit and refrigerator electronic control circuit. The split air-conditioning part of the air heat pump has the following four working modes: cooling mode, heating mode, dehumidification mode, air supply mode. The refrigerator part is divided into a refrigerator and a freezer. There are three working modes: standard mode, energy saving mode, and quick freezing mode.
  6. This device solves the shortcomings of traditional equipment that can only be seen and die but cannot be assembled by hand. It also solves the problem of not being able to weld copper pipes on the equipment, enabling students to repeatedly assemble the system on the device. Training with welding. The whole adopts open and dismountable structural design, and innovatively uses copper tube fixing device to fix each movable joint, which effectively guarantees the damage of the pipeline due to repeated disassembly and assembly, and also reduces the working noise.
  7. In the training platform, a new design was carried out not only using aluminum profiles to assemble the desktop, but also adding a water-receiving chassis under the desktop. The aluminum-profile desktop is not only clean and beautiful, but more importantly, it will not deform when welding copper pipes. The design solves the condensed water generated by the condenser and system pipes in operation, so that water and refrigerated oil can flow smoothly into the water bucket and keep the equipment clean.
  8. Refrigeration simulation software: It mainly includes basic knowledge of refrigeration technology, refrigerant, carrier refrigerant and lubricant, vapor compression refrigeration cycle, refrigeration compressor type and structure principle, air conditioner refrigeration system, air conditioner electrical control system, Household refrigerator refrigeration and control, extension of household refrigeration system, central air conditioning system, etc. The software explains intuitively, making it easy for teachers to teach students easy to learn.
