RUN-AROUND COIL LOOP HEAT RECOVERY
Introduction
With the recent increase in energy costs, heat recovery devices can offer lower utility payments and quick payback. One popular method of heat recovery is a run-around coil loop. A run around coil loop simply moves heat from one air stream to another via two heat exchangers and a heat transfer medium, usually water or glycol. A pump is required to move the medium through the system. Although there are several other methods of air-to-air heat recovery, a run around coil loop may be the only option when airstreams are not adjacent to each other.
