The ventilation and heat dissipation of Gas Generator Set is a key link to ensure the normal operation of the unit and extend its service life. Poor ventilation may cause overheating, decreased efficiency, or even damage to the unit. The following are precautions for ventilation and heat dissipation of Gas Generator Set, covering stages such as design, installation, operation, and maintenance:
1、 Gas Generator Set Design Phase
Calculation of heat dissipation requirements
Calculate the required ventilation volume based on factors such as gas generator set power, ambient temperature, altitude, etc.
Ensure that the exhaust temperature does not exceed the allowable value of the unit.
Ventilation path design
Separation of air inlet and exhaust outlet: To avoid hot air backflow, it is recommended that the air inlet be located at the bottom or side of the unit, and the exhaust outlet be located at the top or the other side.
Air duct optimization: Reduce bends and resistance, and the cross-sectional area of the air duct should be sufficiently large.
Protective measures: Install insect proof nets and rain covers at the air inlet, and install deflectors at the air outlet.
Environmental adaptability
High temperature environment: Increase the heat dissipation area or use forced ventilation.
High humidity environment: Prevent the accumulation of condensed water and install dehumidification devices if necessary.
2、 Gas Generator Set installation phase
Unit spacing
Maintain a distance of at least 1 meter between units to avoid thermal radiation accumulation.
Reserve a maintenance channel of ≥ 0.5 meters around the perimeter.
Gas Generator Set fan installation
The power of the exhaust fan needs to match the design air volume, and the installation height is recommended to be at least 2 meters above the ground.
The direction of the fan should be consistent with the markings to ensure the correct airflow direction.
Sealing and sound insulation
The connection between the ventilation opening and the unit is sealed with fireproof sealant to prevent air leakage.
If noise reduction is required, silencers or soundproofing cotton can be installed, but it is necessary to avoid affecting ventilation efficiency.
3、 Gas Generator Set runtime phase
Monitoring and Alarm
Install temperature sensors to monitor the surface temperature of the unit in real-time.
Set a high temperature alarm threshold to automatically shut down or activate the backup ventilation system in case of overheating.
Load management
Avoid long-term overload operation and regularly check if the load rate exceeds 80%.
When multiple Gas Generator Sets are connected in parallel, distribute the load reasonably to prevent overheating of a single unit.
environmental control
Keep the computer room clean and regularly clean the air inlet filter.
During high temperatures in summer, the machine door can be opened or a temporary exhaust fan can be installed to assist in heat dissipation.
4、 Gas Generator Set maintenance phase
Regular inspection of Gas Generator Set
Fan: Check bearing lubrication and blade balance monthly, and replace belts every six months.
Filter: Check for blockages weekly, clean or replace quarterly.
Air duct: Check annually for dust accumulation or foreign object blockage.
Fault handling
Fan failure: Immediately replace the backup fan to avoid overheating of the unit.
Filter blockage: Shutdown for cleaning or replacement to prevent insufficient air intake.
Abnormal temperature: Check the sensor, ventilation path, and load condition.
Record and analyze
Establish a ventilation system maintenance log to record data such as temperature, air volume, and fault time.
Analyze data trends and identify potential issues in advance.
Through the above measures, the ventilation and heat dissipation performance of the Gas Generator Set can be effectively guaranteed, the failure rate can be reduced, and the service life can be extended. It is recommended that the ventilation system be regularly evaluated and optimized by professionals.
