Energy efficiency of exhaust air heat recovery while

Websupply air and exhaust air streams (see Figure 1). Purge volumes for laboratory applications are typically between 5% and 10%, so additional fan energy is required to move this air. The Whitehead Biomedical Research Building at Emory University in Atlanta, Georgia, uses enthalpy wheels for energy recovery between the supply and exhaust … The rotating wheel heat exchanger is a rotating cylinder filled with an air permeable material, typically polymer, aluminum, or synthetic fiber, providing the large surface area required for the sensible enthalpy transfer. (Enthalpy is a measure of heat.) As the wheel rotates between the supply and exhaust air streams it picks up heat energy and releases it into the colder air stream. The driving force behind the exchange is the difference in temperatures between the opposing … teakplankaWebApr 5, 2016 · With laboratory exhaust air adiabatically cooled prior to passing through the exhaust energy-recovery coils, cooling of the heat-transfer fluid is increased, which further cools outside air and maximizes … eka beka kori boi juwa nodi
