Information

Model for sensible convective heat transfer coefficients for an air to water coil.

This model computes the convective heat transfer coefficient for an air to water coil. The parameters allow a user to enable or disable, individually for each medium, the mass flow and/or the temperature dependence of the convective heat transfer coefficients. For a detailed explanation of the equation, see the references below.

  Corrected coefficient in Taylor expansion of x_a.
  This is for #698.

  Fixed bug in computation of s_w. The old implementation used the current inlet water temperature instead of the design condition that corresponds to UA_nominal.

  First implementation.
