  • Patent number: 7065977
    Abstract: A refrigerated cold beverage merchandiser (10) includes an enclosure defining an insulated, refrigerated display cabinet (25) and a compartment (30) heat insulated therefrom wherein a compressor (40) a condenser (50) and a condenser fan (60) are disposed. The condenser (50) is formed by a plurality of in-line tube banks (52). Each tube bank (52) is a serpentine tube formed a plurality of unfinned, straight tube segments (54) extending in parallel rows (55) between a pair of spaced, opposed end plates (58) and elbow turns (56) connecting neighboring straight tube segments (56) in a conventional manner. Each successive tube bank (52) is arranged with the other tube banks so that respective parallel tube rows (55) are disposed in-line from the front to the rear of the condenser (50) or with each successive tube bank being offset in a slightly staggered arrangement.

  • Patent number: 7036947
    Abstract: Refrigeration system has a display case that defines a display space. The display space has a top area, a bottom area, a front viewing area, and a back area. A cooling element provides cool air to the display space through a series of fans that direct the air to an air outlet. The air outlet then directs the air to an air inlet, thereby forming an air curtain across the front viewing area. A light is located near the back area away from the air curtain. A mirror is spaced from the light and reflects light from the right source through the display space.

  • Patent number: 7000415
    Abstract: A condenser coil for a refrigerated beverage and food service merchandiser includes a plurality of parallel fins between adjacent tubes. In order to reduce the likelihood of fouling by the bridging of fibers therebetween, the spacing of the fins is maintained at a distance of 0.4 to 0.8 inches apart. In one embodiment, the tubes comprise microchannel tubes, with no fins therebetween, and the spacing between the microchannel tubes is maintained in the range of 0.75 inches to optimize the heat transfer performance while minimizing the occurrence of fouling. A supporting structure is provided between microchannel tubes when no fins are included. Also, plural rows of microchannel tubes are provided with separate inlet headings and with the rows being staggered in transverse relationship to enhance the heat transfer characteristic while minimizing the likelihood of fouling.

  • Publication number: 20040123613
    Abstract: A refrigerated merchandiser (100) includes an upright, open-front, insulated cabinet (110) defining a product display area (125) connected in airflow communication with a compartment (120) via an air circulation circuit (122, 114, 116). A high pressure drop evaporator (40) and a plurality of closely spaced fans (70) are disposed within compartment (120). The evaporator (40) is provided with a relatively high fin density heat exchanger coil providing a relatively high air side pressure drop through the evaporator. The increased flow resistance through the evaporator coupled with the plurality of closely spaced fans results in a substantially uniform evaporator outlet temperature profile across the length of the evaporator.
