Minimizing the energy consumed by buildings is of great interest because of stringent state and federal regulations, LEED green-building-certification-system requirements, and ever-increasing energy costs. One way to decrease energy consumption is to recover heat from the air exhausted from buildings. Many heat-recovery devices are available. They include:
Evaporative-Cooling-Enhanced Runaround-Coil Heat Recovery
Energy recovery with runaround coils can be greatly enhanced with evaporative cooling of exhaust air, a long-established fact seemingly forgotten by design engineers.
