Heat Exchanger

In Plain English

A device that moves heat from one fluid to another without mixing them, used throughout HVAC systems.

Definition

A device that transfers thermal energy between two fluid streams without allowing them to mix. Heat exchangers are fundamental components in HVAC systems, boilers, chillers, and heat recovery ventilators. Common types include shell-and-tube, plate-and-frame, and coil heat exchangers, each suited to different flow rates, temperatures, and pressure conditions.

Example

A brazed plate heat exchanger separates the domestic hot water circuit from the boiler water to prevent cross-contamination.
