Information

Model for a constant temperature evaporator or condenser based on a ε-NTU heat exchanger model.

The heat exchanger effectiveness is calculated from the number of transfer units (NTU):

ε = 1 - exp(- UA ⁄ (ṁ c_p))

Optionally, this model can have a flow resistance. If no flow resistance is requested, set dp_nominal=0.

Limitations

This model does not consider any superheating or supercooling on the refrigerant side. The refrigerant is considered to exchange heat at a constant temperature throughout the heat exchanger.
