Abstract
For a supermarket having open refrigerated food display cases and adjacent cold isles and having primary refrigeration systems for refrigerating the cases, energy efficient ventilating means for removing the cold air from the isles and supplying replacement conditioned dehumidified air. The ventilating means includes heat pipes for utilizing the cooling effect of the cold leaving air removed from the isles to precool warm outside make-up air and a reversible refrigerating system for further cooling and dehumidifying the precooled outside air. Excess heat available from the primary market refrigerating system is employed to heat or reheat the dehumidified but now cold outdoor make-up air prior to its entry into the market.
