# HVAC Load Calculator
|
| 13 |
+
|
| 14 |
+
A modern web tool for calculating HVAC cooling and heating loads based on the ASHRAE method.
|
| 15 |
+
|
| 16 |
+
## Features
|
| 17 |
+
|
| 18 |
+
- **Separate Calculators**: Independent cooling and heating load calculators
|
| 19 |
+
- **Step-by-Step Input Forms**: Guided process with validation
|
| 20 |
+
- **Reference Data**: Comprehensive material properties and location data
|
| 21 |
+
- **Visual Results**: Charts and tables for load components
|
| 22 |
+
- **Smart Validation**: Proceed with warnings rather than blocking progress
|
| 23 |
+
- **Downloadable Data**: Export results for student assignments
|
| 24 |
+
- **ASHRAE Method**: Implementation based on industry-standard calculation methods
|
| 25 |
+
- **Extensible Design**: Framework for adding other calculation methods or locations
|
| 26 |
+
|
| 27 |
+
## How to Use
|
| 28 |
+
|
| 29 |
+
1. Select either the Cooling Load Calculator or Heating Load Calculator from the sidebar
|
| 30 |
+
2. Fill in the required information in each step
|
| 31 |
+
3. Review any warnings that appear (you can proceed with warnings)
|
| 32 |
+
4. Calculate results and analyze the output
|
| 33 |
+
5. Export results for your assignments

## Cooling Load Calculator
|
| 36 |
+
|
| 37 |
+
The cooling load calculator helps determine the amount of heat that needs to be removed from a space to maintain comfort conditions. It accounts for:
|
| 38 |
+
|
| 39 |
+
- Conduction through building envelope
|
| 40 |
+
- Solar radiation through windows
|
| 41 |
+
- Internal heat gains (people, equipment, lighting)
|
| 42 |
+
- Infiltration and ventilation
|
| 43 |
+
|
| 44 |
+
## Heating Load Calculator
|
| 45 |
+
|
| 46 |
+
The heating load calculator helps determine the amount of heat that needs to be added to a space to maintain comfort conditions. It accounts for:
|
| 47 |
+
|
| 48 |
+
- Conduction through building envelope
|
| 49 |
+
- Infiltration and ventilation
|
| 50 |
+
- Annual heating energy requirements based on heating degree days
|
| 51 |
+
|
| 52 |
+
## Technical Details
|
| 53 |
+
|
| 54 |
+
- Built with Python and Streamlit
|
| 55 |
+
- Modular design for extensibility
|
| 56 |
+
- Comprehensive reference data based on ASHRAE standards
|
| 57 |
+
- Visualization using Plotly
|
| 58 |
+
- Data export in CSV and JSON formats
|
| 59 |
+
|

+
## Educational Purpose
|
| 61 |
+
|
| 62 |
+
This tool is designed for educational purposes to help students understand the factors that influence HVAC load calculations. It provides a practical way to apply theoretical knowledge and see how different building parameters affect heating and cooling requirements.
