How to Use the Calculator
- Enter the Dry Bulb Temperature in degrees Celsius (°C).
- Enter the Wet Bulb Temperature in degrees Celsius (°C).
- Enter the Relative Humidity as a percentage (%).
- Enter the Air Flow Rate in cubic meters per hour (m³/h).
- Click the "Calculate" button to compute the cooling efficiency and cooling capacity.
Understanding the Results
The calculator provides two key outputs:
- Cooling Efficiency: This is expressed as a percentage and indicates how effectively the swamp cooler is cooling the air. A higher percentage means better efficiency.
- Cooling Capacity: This is measured in kilowatts (kW) and represents the amount of heat the swamp cooler can remove from the air per hour.
Working Principle
The efficiency of a swamp cooler is primarily determined by the difference between the dry bulb temperature and the wet bulb temperature. The greater the difference, the higher the potential cooling efficiency. The cooling capacity is calculated based on the air flow rate and the temperature difference between the dry and wet bulb temperatures.
Practical Tips
- For optimal performance, ensure the wet bulb temperature is as low as possible by using a high-quality water pump and sufficient water flow over the cooling pads.
- Regularly maintain the swamp cooler to ensure clean cooling pads and proper water circulation.
- Consider the ambient conditions (temperature, humidity) when selecting and operating a swamp cooler.
