Key Features
- Thermodynamics-Based Precision Calculation
- Estimates the required cooling capacity (BTU/h and kW) by taking into account area size, solar heat gain, and insulation quality based on energy balance principles.
- Flexible Unit Conversion
- Seamlessly converts room measurements between Square Feet ($\text{sq ft}$), Square Meters ($\text{m}^2$), and Korean Pyung ($\text{평}$) with auto-scaling sliders.
- Interactive Heat Load Simulation
- Provides dynamic visual feedback showing room thermal load status (Low, Moderate, High) alongside animated status indicators.
How to Use
- Select Area Unit & Adjust Size
- Choose your preferred unit ($\text{sq ft}$, $\text{m}^2$, or $\text{Pyung}$) at the top right, then drag the slider to match your room size.
- Select Sunlight Exposure & Insulation
- Tap the card that best matches your room's natural light exposure (Shaded, Moderate, or Sunny) and building insulation quality (Good or Poor).
- Check the Result
- Review the recommended BTU/h output, equivalent kW rating, and detailed heat load adjustments dynamically calculated below.
