Patent number: 7036947Abstract: 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.Type: GrantFiled: September 3, 2004Date of Patent: May 2, 2006Assignee: Carrier Commercial Refrigeration, Inc.Inventors: Sue-Li Kingsley Chuang, Eugene Duane Daddis, Jr.

Patent number: 7000415Abstract: 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.Type: GrantFiled: April 29, 2004Date of Patent: February 21, 2006Assignee: Carrier Commercial Refrigeration, Inc.Inventors: Eugene Duane Daddis, Jr., Robert H.
