When running subcritical simulations, it seems like the stream existing the condenser enters the internal heat exchanger without any subcooling.
COP is often better when including some subcooling of the refrigerant with the sink inlet stream. Since subcooling could be applicable to all cycle types, it would be good to be able to toggle it on and off in the general configuration, e.g., before setting the IHX subcooling.
The ideal way to define the size of the sub-cooler would be to use T_approach as an input, i.e., temperature difference between the refrigerant leaving the sub-cooler and sink inlet stream entering the sub-cooler.
