System Requirements Explained
Based on your humidification parameters, these calculations show the water flow rate needed to achieve your target humidity levels. The air volume represents the total amount of air being conditioned per your specified system parameters.
How These Results Help You:
- Flow Rate (kg/hr or lbs/hr): Determines the water supply line size and pump capacity needed for your system
- Flow Rate (gals/hr): Reference point for comparing with system specifications and nozzle flow rates
- Flow Rate (l/hr): Industry standard for HVAC humidification system sizing
- Air Volume: Helps determine proper nozzle spacing and distribution for uniform coverage
- System Type: Guides selection between siphon-feed or pressure-feed nozzle systems
Next Steps:
- Use your calculated flow rate to select appropriately-sized nozzles from our catalog
- Consider system redundancy (typically 1.2-1.5x calculated flow for margin)
- Account for pressure drop losses in distribution lines
- Verify supply water quality meets humidification standards
- Contact our specialists to optimize your final system design
Humidification Calculator Guide
This advanced calculator helps you determine the precise water flow requirements for your humidification system. By understanding your system needs, you can select the right nozzles, pumps, and accessories for optimal performance.
Step-by-Step Instructions:
- System Type: Choose between siphon-feed (gravity-based, simpler) or pressure-feed (active pump, more control) systems
- Room Measurement: Enter either total room volume OR room dimensions (length × width × height)
- Air Volume Method: Select air changes per hour (typical: 4-8 for offices, 6-12 for clean rooms) or your exhaust fan capacity
- Temperature Settings: Enter current and target temperatures (system can cool/heat slightly through evaporative effects)
- Humidity Targets: Specify current and desired relative humidity levels (optimal indoor RH: 30-50%)
- System Schedule: Enter what percentage of each hour your humidification runs (50% = runs 30 min/hour)
- Calculate: Click to see your customized system requirements
Understanding Your Results:
- Flow Rate in Multiple Units: We show kg/hr, gals/hr, and l/hr so you can compare with equipment specs in any region
- Air Volume Metrics: Displayed in your chosen units (ft³/hr & ft³/min for US; l/hr & l/min for metric)
- Zero Flow Results: If current and target conditions are identical, flow rate will be 0 (system already at target)
- High Flow Requirements: Large differentials or frequent air changes may require multiple nozzles or larger system capacity
Best Practices for Humidification Systems:
- Always oversize by 20-50% for safety margin and equipment longevity
- Multiple smaller nozzles provide better distribution than one large nozzle
- Maintain supply water within specification (typical: TDS < 500 ppm)
- Install drain lines to handle nozzle blowdown and system flushing
- Use quality filters to protect nozzles and extend service life
- Monitor and adjust system on-time based on actual humidity readings
