ABSTRACT:
A reverse cycle heat reclaim coil in a refrigeration system having compressor, condenser and receiver means on the high side, including first valve means for selectively connecting the heat reclaim coil between the compressor discharge side and the condenser means to obtain heat reclamation during winter operations, and second valve means for selectively connecting the heat reclaim coil between the condenser and receiver means to obtain refrigerant subcooling during summer operations. The invention also includes the method of selectively connecting the heat reclaim coil in reverse cycle refrigerant flow in seasonal heat reclamation and subcooling modes.
