STRATEGIC MODULAR SECONDARY REFRIGERATION

摘要

A commercial refrigeration network including refrigeration system unit (10) constructed and arranged for placement in strategic proximity to corresponding product cooling zones within the shopping arena (A) of a food store (5), each refrigeration unit (10) having a condensing unit rack (20) configured to accommodate the maximum refrigeration loads of its associated zone with an optimum floor space footprint in the shopping arena (A), and the condensing unit rack (20) including a plurality of multiplexed compressors (21), condenser (12) and associated high side (22) and low side (31) refrigerant delivery and suction conduits operatively connected to evaporators (23) for cooling the corresponding zone, and the network (C) also including another cooling source (11) remote from said modular refrigeration units (10) and constructed and arranged for circulating a fluid coolant in heat exchange relationship with the condenser (19) to obtain optimum condensing and efficiency of said evaporators (23) in cooling the corresponding zone.
