HIGHLY ENERGY EFFICIENT HEAT RECLAMATION MEANS FOR FOOD DISPLAY CASE REFRIGERATION SYSTEMS ABSTRACT OF THE DISCLOSURE: A refrigeration system for food display cases is disclosed, having a heat reclamation coil, to which hot gas discharged by the system's compressors may be diverted in accordance with the conventional practice, to provide heat energy usable for heating and/or controlling the moisture content of the interior store area. An improvement in such heat reclamation systems is disclosed, in that the output of the heat reclaim coil is continuously sensed to determine whether it is in an all-liquid condition, or alternatively, a mixture of liquid and gas. If the former, valving is automatically operated to bypass the liquid output from the heat reclaim coil around the system's condenser to the liquid line downstream from the condenser, so that the heat reclaim coil functions as the system's condenser in these circumstances. If the output from the heat reclaim coil is a gas-liquid mixture, it is returned to the input side of the system's condenser to reduce the energy required for normal condenser operation.
