The air compressor room on the second floor is technically feasible, but requires a comprehensive assessment of the building structure, equipment characteristics, safety specifications and operation and maintenance requirements. The following analysis from a professional point of view:
adaptability Assessment of 1. Building Structures
- bearing capacity of floor slab
- the weight of the air compressor host is usually between 1-5 tons, and it is necessary to confirm whether the design load of the second floor meets the requirements. The general industrial building floor bearing standard is 500kg/m², if the equipment centralized layout, the need for structural reinforcement or decentralized layout.
- The load of auxiliary equipment such as gas tank and dryer shall be calculated separately, and the dynamic load coefficient shall be considered (usually 1.2-1.5 times of static load).
- Vibration reduction and isolation measures
- when the air compressor is running, the vibration frequency is 25-50Hz, and the rubber damping pad or spring damper shall be installed on the equipment base to reduce the vibration transmission efficiency to less than 5%.
- Flexible supports and hangers shall be used for pipeline supports to avoid fatigue fracture of pipeline caused by vibration.
Key points of 2. environment and safety control
- noise control
- when the air compressor is running, the noise can reach 75-90dB(A), and compound noise reduction measures should be taken:
- the equipment foundation shall be equipped with sound-proof cover and lined with sound-absorbing cotton (thickness ≥ 50mm).
- Doors and windows are made of double-layer soundproof glass, and the wall is additionally provided with soundproof layer (density ≥ 80 kg/m & sup3;).
- Ensure that the noise at 1 meter outside the machine room is ≤ 65dB(A), which meets the Environmental Noise Emission Standard for Industrial Enterprises.
- Heat dissipation and ventilation design
- the heat dissipation of the air compressor is estimated by 5%-8% of the equipment power, and a forced ventilation system is required:
- install explosion-proof axial flow fan with air change rate ≥ 15 times/hour.
- The air inlet is provided with a three-stage filter device to prevent dust from entering the machine room.
- During the high temperature period in summer, the temperature of the machine room shall be monitored, and industrial air conditioning shall be added if necessary.
- Gas leakage protection
- combustible gas detector (range 0-100% LEL) is configured, and the alarm value is set to 25% LEL.
- Installation of mechanical exhaust device, and gas alarm system linkage, to ensure leakage within 3 minutes to complete ventilation.
3. system configuration optimization recommendations
- piping layout principle
- the main pipeline is laid along the wall to reduce the number of floor crossing, and the pressure loss is controlled within 0.02MPa/100 m.
- The elbow adopts a large radius of curvature (R≥ 3D) to reduce the local resistance coefficient.
- An independent annular pipe network is set at the gas point on the second floor to avoid pressure drop affecting the operation of the equipment.
- Maintenance Convenience Design
- reserved equipment maintenance channel, width ≥ 1.2 m, to meet the demand of forklift traffic.
- The lifting point shall be configured, and the bearing capacity shall be ≥ 1.5 times of the equipment weight.
- Drainage ditch and oil collection tank shall be set to prevent the leakage of lubricating oil from polluting the lower space.
4. typical industry application cases
| Industry field | configuration Scheme of Computer Room on the Second Floor | operation effect |
|---|
| automobile Manufacturing | screw air compressor + frequency conversion control + soundproof cover | noise ≤ 62dB(A), energy consumption reduced by 18% |
| food Processing | oil-free scroll air compressor stainless steel pipe | oil content of compressed air <0.01 mg/m & sup3; |
| textile printing and dyeing | centrifugal air compressor + heat recovery device | the waste heat utilization rate reaches 75%, and the annual power saving is 120000 kW · h. |
5. compliance review points
- fire Code
- the fire resistance rating of the machine room shall not be lower than Grade II, and portable dry powder fire extinguisher (MF/ABC5 type) shall be provided.
- The cable through-wall hole shall be blocked with fireproof mud, and the fire resistance limit shall be ≥ 3 hours.
- Special Equipment Management
- the use registration certificate shall be applied for the gas storage tank, and the periodic inspection period shall be 3 years.
- Safety valves, pressure gauges and other accessories shall be subject to mandatory verification to ensure that they are used within the validity period.
Conclusion
the air compressor room installed on the second floor shall pass the structural safety assessment, environmental impact assessment and fire control acceptance, and take targeted vibration reduction, noise reduction and ventilation measures. In the actual project, it is suggested to entrust professional institutions to carry out feasibility study and formulate technical scheme according to the production process requirements to ensure the safe and stable operation of the system.
