Automatic air -conditioning system test training device

Based on the automotive automatic --r -conditioning system, the device fully shows the structure and work process of automobile automatic --r -conditioning system.

It is suitable for the teaching needs of various schools theory and m--ntenance tr--ning for automotive automatic --r -conditioning systems.

2. Functional characteristics

1. Real -operated automobile automatic --r -conditioning system, fully display the composition and work process of automobile automatic --r -conditioning system.

2. From the three -phase motor as the source of power, drive the --r conditioner compressor to work. Operate the --r -conditioning control panel to realize the work process and working principle of automobile automatic --r -conditioning system.

3. The tr--ning table panel adopts a 4mm thick corrosion resistance, strike, pollution resistance, fire prevention, and moisture -proof ** aluminum -plastic panels. The surface is sprayed with primer p--nting by special crafts; With work principle diagram; students can intuitively control the circuit diagram and physical objects, understand and analyze the working principle of automobile automatic --r -conditioning system.

4. Detective terminals are installed on the tr--ning table panel. You can directly detect the electrical signals of the circuit components of the --r -conditioning system on the panel, such as resistance, voltage, current, frequency signals, etc.

5. Tr--ning tablet panels are installed with pressure gauges, temperature meters, real -time display of the pressure of --r -conditioning pipelines, and changing the temperature of the --r inlet and outlet.

6. The tr--ning desk provides students with practical work platforms such as injection refrigerant and leakage.

7. The device detection panel is equipped with a 20cm steel table on the front base in front, which is convenient for placing data and detection instruments.

8. The bottom of the tr--ning table is welded with steel structure, and the round hand rod is welded on the front/sides. The surface is treated with a spraying process, with a self -locking wheel device. It is flexible, safe, reliable, and durable.

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. This device is selected to use ordinary heat exchangers and column tube heat exchanges to compare the effects of two types of heat exchanges.

4. Double -water pump owner and sideline design, fresh water supplement and waste heat water circulating design, switching the heating process in the countercurrent and flowing heat, and closer to the actual application of industrial applications.

5. Multiple sets of heating pipe preheating systems, fast and uniform heating speed, adjustment of the preheating voltage, platinum thermal resistance+thyristor+heating pipe as the m--n control method for thermal temperature.

6. The hot and cold water tanks are covered with coverage, and are equipped with a high level of display device to observe water level changes and have the function of upper and lower water; the water level of the cold water tank can be automatically controlled.

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