In many fan systems, the amount of electrical energy used to drive the motor is a small fraction of the thermal energy carried by the air or gas. When this thermal energy is wasted, or dumped to atmosphere, it can represent a huge opportunity for energy savings through heat recovery. In new commercial air conditioning applications where there is a high demand for outdoor air, recovering the “cool” energy in the air that is spilled is often immediately cost effective, without any payback period. Industrial thermal processes such as boilers, foundry dust exhaust, and steel mill ovens, (among others) are often great candidates for heat recovery.

In this course you will be introduced to 5 different strategies for thermal energy recovery, including the use of: heat wheel, air-to-air, air-to-water, water-to-air, and glycol run-around heat recovery systems. The course also includes a method for estimating the potential energy savings, so you can see if the project has enough value to proceed with the design and implementation.
