EAHE air temperature experimentally, mathematically and numerically investigated.
- class="label">•
The thermal effect of design and operating parameters is studied.
- class="label">•
In winter, the increment in pipe diameter, pipe length and pipe space, increase outlet air temperature.
- class="label">•
Pipe material doesn’t affects so much the outlet air temperature.
- class="label">•
In winter, as air velocity increases, the outlet air temperature decrease.
