1. System summary:

The variable --r volume ventilation and smoke discharge tr--ning system According to its tobacco prevention and smoke and exhaust system, it is divided into a smoke control system and a smoke -proof system. The equipment is designed as a mechanical pressure supply --r supply system and mechanical smoke exhaust system.

Variable --r volume ventilation and smoke exhaust tr--ning system consists of an analog room equipment and smoke exhaust fan system (m--nly consolidated by --r outlets, wind valves, smoke discharge windows and smoke exhaust fan, fire firewood valve, --r supply fan, --r supply --rway, smoke exhaust, and smoke exhaust. The --r ducts and related fire detectors and linkage control systems form a full system intelligent operation, and the energy -saving technology control of frequency conversion technology controls the energy conservation control requirements through various system components of the frequency conversion technology control system.

2. Technical parameters

1. Enter power supply: single -phase three -line ～ 380V ± 10% 50Hz 50Hz

2. Working environment: The environmental temperature range is -5 ° C ~+40 ° C relative humidity <85%(25 ° C) altitude <4000m

3. Device capacity: <3.8kva

4, shape size: 3000mm × 1000mm × 1600mm

5. Safety protection: It has leakage voltage and leakage current protection device, and safely meets national standards

6. Working environment: The environmental temperature range is -5 ℃ ～+40 ℃ The relative humidity is <85%(25 ℃) altitude <4000m

Third, systemic characteristics

1. The integrity of the wind system, the system and the real subway --r -conditioning system, and the wind system processing system is the same, and the miniaturization shows the characteristics, structure, and control methods of the subway --r -conditioning system. Essence

2. The system and the real ventilation smoke exhaust system have the same principles of wind treatment systems, and miniaturization shows the characteristics, structure, and control methods of the ventilation smoke exhaust system.

3. The device visually shows the system structure and working principle of the ventilation system, which is convenient for teachers 'demonstration explanations and students' understanding of textbook knowledge. The structure is reasonable, the shape of the beautiful shape is reasonable and compact, and the shape is beautiful and generous. The tr--ning table also has four universal wheels and four fixed regulatory agencies to facilitate movement and fixation.
