Estimation of the surface and length of a solar exchanger in a simple copper tube (without fins) immersed in a solar thermal buffer

.Xls spreadsheet (OpenOffice compatible) to determine the surface and length of a solar exchanger for a solar tank or thermal buffer. This exchanger is the primary solar exchanger, so it is mounted on the primary circuit side. It is the exchanger found at the bottom of the solar balloons on the market.

Settings:

- Surface of a sensor
- Number of sensors
- Total collector area
- Solar power per m²
- Total solar power
- Delta T °
- Pipe diameter in mm
- Coefficient of performance of the exchanger

Results:

- Coil surface required
- Length of the coil
