Publication number: 20100242506Abstract: A refrigeration apparatus having an evaporator fan motor control includes an evaporator to remove heat energy from the air in a cooled storage space. The evaporator transfers the heat energy to a refrigerant. At least one evaporator fan moves air from the cooled storage space across the evaporator to improve the transfer of heat energy into the refrigerant. The one or more evaporator fans have an energy consumption and generate a waste heat energy. A refrigeration control unit at least controls the operation of the one or more evaporator fans. During an off mode, the one or more evaporator fans are operated in a reduced energy consumption mode to reduce the energy consumption of the one or more evaporator fans and to reduce the waste heat while still defrosting the evaporator in the off mode.Type: ApplicationFiled: May 22, 2006Publication date: September 30, 2010Applicant: UNIVERSAL NOLIN COMPANY LLCInventors: Eugene Duane Daddis, JR., Mark A.

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.
