Typically, heat exchangers are used to allow heat from liquids or gases to pass to other liquids or gases, without the two coming into direct contact. Essentially a heat exchanger transfers the heat without transferring the fluid that carries the heat.

Heat exchanges are often used as part of heating, cooling or heat recovery systems.

Heat exchange devices can be used in a number of processes, including:
*Air conditioning systems and refrigerators which remove heat from a room or compartment where it is not required.
*Heat pumps.
*Heat recovery on ventilation systems.
*Waste water treatment.
*Modes of transport (aircraft, buses, trains and so on).
*Nuclear and power plants.
*Energy efficient showers.
*Machinery and engines.

The two most common types of heat exchangers are the shell and tube, plate or fin:
*With shell and tube heat exchangers, one fluid flows through a set of metal tubes while another fluid passes between them, within a sealed unit. Both of the fluids can flow in the same direction which is called parallel flow, the fluids can travel in opposite directions, known as counter flow or counter current and they can also flow at right angles (cross flow).
*Plate or fin heat exchangers metal fins with large surface areas and air passes between them. This construction allows periodic inspection, cleaning and disassembly if needed. This system is often used for chilled beams or integrated service modules.

Earth-to-air heat exchangers draw ventilation supply air through buried ducts or tubes. As the temperature of the ground below 3m is practically constant, it substantially reduces ambient air temperature fluctuations. It therefore provides space conditioning throughout the year, with the incoming air being heated in the winter and cooled in the summer by means of earth coupling.

The appropriate heat exchanger can be selected by consideration of:
*Space availability.
*Fluid flow capacity.
*Pressure limits and temperature ranges.
*Thermal performance.
*Requirements for maintenance and repair.
