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.

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.

A refrigeration cabinet having insulated outer walls and an access door for accessing the cabinet interior; a space defined between an insulated back wall and an inner panel of the cabinet, the space being vertically divided by a pair of partitions defining a central vertically-extending cold air passage for cold air flow having cold air discharge openings in fluid communication with the cabinet interior, and two outer vertically-extending return air passages for return air flow disposed on opposite sides of said cold air passage and having return air inlet openings in fluid communication with the cabinet interior, said return air inlet openings being downwardly spaced from at least some of said cold air discharge openings; and air circulation means adapted to draw air from the cabinet interior through said return air inlet openings into said return air passages, to cool said air and to expel cool air into the cabinet interior through said cold air discharge openings from said cold air passage, a circulatory air flow being created in the cabinet interior with cool air discharged forwardly and downwardly from said inner panel and return air drawn into said return air passages for refrigeration and continued circulation.
