The Run-Around Coil Energy Distribution System (EDS) by HUBER & RANNER is a high-efficiency airside energy recovery solution designed to reduce the energy consumption of HVAC systems by reclaiming waste heating and cooling potential from exhaust air streams.
Energy recovery is an option for organizations using a direct exchange system that's increasingly being written into building codes and ASHRAE standards. There are two basic types: airside and waterside.
water-side heat recovery. How is energy recovered?(Airside energy recovery was covered in ENEWS-29/5.)[2] Interest in heat recovery from the condensers of water-cooled chillers has also increased.

Within HTM-compliant air handling systems, energy recovery is typically achieved using indirect methods that maintain full separation between supply and extract air paths.

Such details provide a deeper understanding and appreciation for High-Rise Airside Energy Recovery Systems.
Air-to-Air Energy Recovery in HVAC Systems.Further, the exhaust-air energy-recovery system must be installed with bypass dampers or other controls that permit airside economizer operation when such economizers are prescribed by Section 6.3.1.1 of the standard.
energy recovery systems capture waste heat from chimney exhaust.

Furthermore, visual representations like the one above help us fully grasp the concept of High-Rise Airside Energy Recovery Systems.
