Patent number: 8151587Abstract: 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.Type: GrantFiled: December 15, 2003Date of Patent: April 10, 2012Assignee: Hill Phoenix, Inc.Inventors: Robert Hong Leung Chiang, Eugene Duane Daddis, Jr., Kwok Kwong Fung, Sue-Li Kingsley Chuang

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: 6973800Abstract: A refrigeration system comprises a display case having a viewing area with the first side and a second side. An air outlet on the first side guides air across the viewing area to an air inlet on the second side. A first fan and a second fan communicate with the air inlet. A volume extends between the air inlet and the first and second fans. The partition divides this volume between the first and second fan.Type: GrantFiled: March 15, 2004Date of Patent: December 13, 2005Assignee: Carrier Commercial Refrigeration, Inc.Inventors: Sue-Li Kingsley Chuang, Eugene Duane Daddis, Jr.

Publication number: 20040069002Abstract: A refrigeration system comprises a display case having an exterior and an interior, the interior comprising a top surface, a bottom surface, a back area and a front viewing area at least partially defining a display space. A cooling element cools air within the display space. A first air outlet on the display case guides the cool air across the front viewing area along a first path. A second air outlet on the display case guides warm air across the viewing area along a second path wherein the second air outlet comprises an opening from the exterior to the interior of the display case. An air mover communicates with the cooling element directing air to the first air outlet.Type: ApplicationFiled: October 9, 2002Publication date: April 15, 2004Inventors: Sue-Li Kingsley Chuang, Eugene Duane Daddis, Philip Lavrich
