1. What is AC Condensate Production?

AC condensate production refers to the amount of water that is removed from the air by an air conditioning system as it cools and dehumidifies the air. This condensation occurs when warm, humid air passes over the cold evaporator coils.

2. How Does the Calculator Work?

The calculator uses the condensate production formula:

\[ Condensate = \frac{Air\ Flow\ CFM \times \Delta Humidity\ Grains}{7000} \]

Where:

Explanation: The formula calculates the daily condensate production in gallons by multiplying air flow rate by humidity difference and converting from grains to gallons.

3. Importance of Condensate Calculation

Details: Accurate condensate calculation is crucial for proper drainage system design, preventing water damage, ensuring system efficiency, and maintaining indoor air quality by effectively removing excess moisture.

4. Using the Calculator

Tips: Enter air flow in CFM (cubic feet per minute) and humidity difference in grains per pound of dry air. Both values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is CFM in air conditioning?
A: CFM stands for Cubic Feet per Minute and measures the volume of air flowing through the HVAC system per minute.

Q2: What are grains in humidity measurement?
A: Grains are a unit of measurement for absolute humidity, where 1 grain = 1/7000th of a pound of water vapor.

Q3: Why is condensate production important?
A: Proper condensate management prevents water damage, mold growth, and ensures efficient system operation by removing excess moisture from the air.

Q4: What affects condensate production?
A: Condensate production depends on air temperature, relative humidity, air flow rate, and the cooling capacity of the AC system.

Q5: How is ΔHumidity Grains determined?
A: It's the difference between the incoming air humidity and the saturation humidity at the evaporator coil temperature, typically measured with psychrometric charts or sensors.
