RUN-AROUND COIL LOOP HEAT RECOVERY
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.
