Class HeatStream

java.lang.Object

neqsim.process.equipment.heatexchanger.heatintegration.HeatStream

All Implemented Interfaces:

Serializable

public class HeatStream
extends Object
implements Serializable

Represents a single process stream for heat integration (pinch) analysis.

A heat stream has a supply temperature, target temperature, heat capacity flow rate (MCp), and can be classified as HOT (needs cooling) or COLD (needs heating).
