Heat Exchanger

Overview

	Size / Design Variable	Heat Transfer Area
	Costing Variable (Built-in Model)	Heat Transfer Area
	Costing Variable (User-Defined Model)	Heat Transfer Area in m2
	Emissions Port	No
	Hosts	Heat Exchanging Procedure

A Heat Exchanger is used to represent an equipment resource used to host a heat exchanging procedure with a main objective to exchange heat between two streams which come in contact within the exchanger and have a difference in temperature. This will increase the temperature of the cold stream and decrease the temperature of the hot stream. The procedure can be executed in a batch or continuous mode.

Cooler: Equipment Tab

See Heater: Equipment Tab.

Sizing: Design Mode

In Calculate (Design Mode), the user specifies the Maximum Heat Transfer Area and the system computes the Number of Units and the Heat Transfer Area. See also Heat Exchanging: Modeling Calculations.

Sizing: Rating Mode

In User-Defined (Rating Mode), the user specifies the Number of Units and the Heat Transfer Area.

Costing

Built-in equipment purchase cost functions are available for three different types of heat exchangers: plate-and-frame, spiral, and shell-and-tube. The cost is based on the total heat transfer area and the material of construction which is assumed to be CS.
