What are the requirements for the air compressor room

The design of the air compressor room needs to comprehensively consider multiple factors such as safety, efficiency, and environmental protection. The following is a detailed explanation for you from the aspects of site selection, environment, layout, and safety:

1. Computer room site selection requirements

1. Stay away from sensitive areas
   • Keep a distance of at least 10 meters from the office area and production workshop to avoid noise (75-95dB) and vibration.
   • Avoid storage areas for dust and inflammable and explosive materials (such as paint warehouses and gas stations).
2. Terrain and ventilation
   • Priority should be given to higher locations in the factory area and natural ventilation should be used to dissipate heat.
   • Avoid low-lying wet areas and prevent equipment from getting wet.

2. Environmental control requirements

1. temperature and humidity
   • temperature: It is recommended to control it at 0~40℃ (water-cooled models ≥5℃), and heat dissipation needs to be strengthened in summer (such as exhaust fans, water mist sprays).
   • humidity: Relative humidity ≤85%, avoid condensation water accumulation.
2. air quality
   • Eliminate corrosive gases (such as SO ˇ, NH) and chemical volatiles (such as benzene).
   • Install a dust screen (aperture ≤0.5mm) at the air inlet and clean it regularly.
3. cleanliness
   • The floor is made of epoxy floor or non-slip ceramic tiles and is cleaned once a week.
   • Use mildewproof coating on the walls, and it is forbidden to pile up debris.

3. Equipment layout specifications

1. Core equipment configuration
   • air storage tank: Volume ≥ 10% of the air compressor displacement, place it in front of the dryer (buffer pressure fluctuations).
   • Dryers and filters: Layout according to the order of “air compressor → air storage tank → primary filter → cold dryer → precision filter”.
2. Pipeline optimization
   • The diameter of the main pipe is greater than or equal to the size of the air compressor outlet, and the elbows are reduced (pressure loss increases by 0.5 – 1bar per elbow).
   • The slope of the drainage pipe is ≥2%, which facilitates the discharge of condensate.
3. maintenance space
   • The equipment spacing is ≥1.5 meters, and the reserved channel width is ≥1 meter.
   • Reserve an operating space of 0.8 meters in front of the control cabinet.

4. Safety and protection requirements

1. fire and explosion prevention
   • The machine room adopts fire doors (fire resistance limit ≥1 hour), and explosion-proof lights are installed on the walls.
   • Equipped with carbon dioxide fire extinguishers (1 set per 20㎡).
2. electrical safety
   • Power supply voltage fluctuation ≤±5%, ground resistance ≤4Ω.
   • The motor is equipped with an overheating protector to prevent open-phase operation.
3. equipment maintenance
   • The oil and gas separator filter elements are replaced every 2000 hours, and the lubricating oil is replaced every 4000 hours.
   • The safety valve is calibrated once a year, and the pressure gauge is calibrated once every six months.

5. Energy saving and noise reduction design

1. energy-saving measures
   • Select a permanent magnet variable frequency air compressor (energy saving more than 30%) and install a waste heat recovery device (hot water/hot air utilization).
   • The air compressor group is jointly controlled, and the number of operating units is automatically adjusted according to the air consumption.
2. noise control
   • The equipment foundation is equipped with shock-absorbing pads, and the wall of the machine room is filled with sound-absorbing cotton (thickness ≥5cm).
   • Install a muffler at the exhaust outlet (noise reduction by more than 15dB).

6. Other matters needing attention

• identity management: Equipment is posted with operating status signs (such as “in operation” and “under maintenance”).
• emergency lighting: Explosion-proof emergency lights are installed in the machine room, with illuminance ≥30 lux.
• data archiving: Keep equipment instructions and maintenance records (at least 3 years).

It is recommended to carry out professional design in accordance with the “GB50029 -2014 Design Code for Compressed Air Stations” and entrust a third-party agency to conduct safety assessment every year.
