Centralized refrigeration systems have been in use for years. Once considered the flagship of the industry, they offer food store managers a flexible solution with design, compressor, and refrigerant options to meet individual store needs.
A centralized system, typically referred to as a “parallel rack,” consists of one or more racks housed in a mechanical room located in the back of a supermarket sized for the store’s entire refrigeration needs. Centrally located on the roof are usually large air-cooled condensers sized to match the requirements of the large rack systems. The racks provide the refrigeration to display cases and walk-in coolers throughout the store.
