1. What is Condensate Water Calculation?

The condensate water calculation formula determines the amount of water condensed during dehumidification processes. It's essential for HVAC system design, industrial drying processes, and moisture control applications.

2. How Does the Calculator Work?

The calculator uses the condensate water formula:

Where:

• \( Condensate \) — Water condensate rate (kg/hr)
• \( Air Flow \) — Air flow rate (cfm)
• \( \Delta h \) — Enthalpy difference (Btu/lb)
• \( h_{fg} \) — Latent heat of vaporization (Btu/lb)

Explanation: The formula calculates the amount of water that condenses when moist air is cooled below its dew point, based on the energy removed during the dehumidification process.

3. Importance of Condensate Calculation

Details: Accurate condensate calculation is crucial for proper drainage system design, preventing water damage, ensuring efficient HVAC operation, and maintaining indoor air quality.

4. Using the Calculator

Tips: Enter air flow in cfm, enthalpy difference in Btu/lb, and latent heat in Btu/lb. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical value for h_fg?
A: For water at standard conditions, h_fg is approximately 970 Btu/lb, but it varies with temperature and pressure.

Q2: How is Δh determined?
A: Δh is the difference in enthalpy between the incoming and outgoing air streams, typically obtained from psychrometric charts or calculations.

Q3: What units should I use for air flow?
A: This calculator uses cfm (cubic feet per minute). Ensure consistent units throughout the calculation.

Q4: Why is condensate calculation important in HVAC?
A: Proper condensate calculation ensures adequate drainage capacity, prevents overflow, and maintains system efficiency and indoor air quality.

Q5: Can this formula be used for industrial drying applications?
A: Yes, this formula is applicable to various dehumidification processes including industrial drying, air conditioning, and moisture control systems.
