Components.OneTempWall1D

Discretised one-temperature wall for tube-fin heat exchangers.

The wall is split into N segments. heatPort_a[i] is the refrigerant-side port and heatPort_b[i] is the air-side port for segment i; both see the same wall temperature T[i]. m_wall is the total wall mass shared by all N segments. The initial wall temperature varies linearly from T_in_start to T_out_start along the discretisation.

Usage
