Easy does it
This is a solar air heating system designed to warm indoor spaces using sunlight. Here's a step-by-step explanation of how it works:
1. System Installed on the Roof.
A solar air collector is installed on the roof, facing the sun to maximize sunlight absorption.
2. Sunlight
Sunlight heats the air inside the collector.
3. Cold Air Intake
Cold air from the indoor space is drawn into the system through a duct at the bottom (marked “Cold air entering the system”).
4. Air Heating
As the cold air passes through the solar collector, it absorbs heat from the sunlight, becoming warm.
5. Disc Switch
A disc switch senses the temperature inside the solar collector and activates the air blower once a certain temperature is reached.
6. Air Blower
The air blower moves the heated air from the collector into the indoor space.
7. Check Valve
A check valve ensures one-way airflow, preventing warm air from escaping back to the collector.
8. Thermostat Regulator
A thermostat inside the indoor space regulates the system, turning it on or off based on the desired room temperature.
9. Warm Air Circulation
The warm air is released into the room (“Hot air coming from the system”), raising the indoor temperature.
This air eventually cools and is recirculated back into the system, completing the loop.
This setup is an energy-efficient way to use solar power for space heating, especially in colder months.
