REFRIGERATION UNIT FOR COLD SPACE MERCHANDISER

摘要

A modular refrigeration unit comprising a condenser assembly and an evaporator assembly is bottom-mounted inside a merchandising display cooler such that cool air emerging from the evaporator assembly rises in a plenum defined between an insulated back wall of the cooler and an interior back panel. The cold air passage is centrally disposed between return warm air passages for returning air from the inside of the cabinet into the evaporator assembly. Air inlet and outlet openings are provided at selected locations on the interior back panel. The evaporator assembly is disposed above an evaporator pan which is integrally formed with a well for collecting condensed water vapor and discharging the collected moisture on the other side of a bulkhead insulating the evaporator assembly from a condenser assembly exposed to the ambient atmosphere. The liquid discharged from the evaporator pan is collected in a condensate tray disposed beneath the condenser assembly and housing a condenser coil provided in a serpentine path for carrying coolant from a compressor to a heat exchanger forming part of the condenser assembly. The condensate tray is formed with projections which support brackets that space the condenser coil from the tray so as to minimize any abrasion between the coil and the tray which could result in coolant leaks.
