Does the condenser need to be designed for subcooled condensation?

Does the condenser need to be designed with subcooling? For example, by 5 degrees or 10 degrees, to ensure complete condensation?
It is generally not necessary. If the condenser is well-designed, it usually has this function
I personally think it is necessary, as there is a significant difference in the heat transfer coefficients between the subcooling section and the condensation section; if subcooling is required, the heat transfer area needs to be increased
Subcooling is designed according to process requirements, requiring a larger heat transfer area.
Subcooling is generally not required, as it imposes high technical demands
It depends on your specific process requirements. Is the condensed material very valuable?
Generally, condensers need to be designed to meet the requirements of condensation cooling: firstly, to ensure that the steam is fully condensed; secondly, to reduce the saturated vapor pressure of the liquid after it has been cooled to a certain extent, thereby minimizing losses due to liquid evaporation. Even if further cooling is not required, it should be designed this way to provide flexibility for the process operation.
