Centrifugal fans and heat exchangers can work together in various applications, particularly in systems where air or gas needs to be circulated and heat needs to be transferred or removed. Here's how they can work together:

Heat Removal/Exchange: In many industrial processes or HVAC systems, heat needs to be removed or exchanged to maintain optimal temperatures. Heat exchangers are used to transfer heat from one fluid (or gas) stream to another without the streams mixing. A centrifugal fan can be employed to circulate one of these streams, either the fluid being cooled or the fluid used for cooling, through the heat exchanger.

Air Conditioning and HVAC Systems: Centrifugal fans are commonly used in air conditioning systems to circulate air through the system. Heat exchangers are also integral components in air conditioning units, where they transfer heat between the indoor and outdoor air streams. The fan helps to move the air through the heat exchanger, facilitating the heat exchange process.

Industrial Processes: In various industrial processes, heat exchangers are utilized to control temperatures of fluids or gases involved in the process. Centrifugal fans can be used to move these fluids or gases through the heat exchanger, enhancing the efficiency of the heat transfer process. For example, in chemical processing plants, heat exchangers are used to cool down hot gases or liquids, and centrifugal fans help in circulating these fluids through the exchangers.

Heat Recovery Systems: Heat exchangers are often employed in heat recovery systems to capture waste heat from processes or exhaust streams. Centrifugal fans can be used to aid in the circulation of the fluids or gases involved in the heat recovery process, ensuring efficient heat transfer and utilization.

Ventilation Systems: In buildings or confined spaces where ventilation is necessary, centrifugal fans are used to circulate air. Heat exchangers can be integrated into these ventilation systems to recover heat from the outgoing air stream and transfer it to the incoming air stream. The fan helps to facilitate the movement of air through the heat exchanger.

Centrifugal fans and heat exchangers can work together in various applications to facilitate the circulation of fluids or gases and to transfer or exchange heat efficiently. They are often integral components in HVAC systems, industrial processes, and ventilation systems where heat transfer and air circulation are essential.
