Publication number: 20190072308Abstract: A refrigeration system for a temperature-controlled storage device includes a refrigeration circuit, a cooling circuit, and a controller. The refrigeration circuit includes a compressor driven by a brushless DC motor operable at multiple different speeds, a first heat exchanger, an expansion device, and a cooling unit in fluid communication via a first working fluid. The cooling circuit includes a pump and a second heat exchanger in fluid communication with the first heat exchanger via a second working fluid such that the first heat exchanger is liquid-cooled by the second working fluid. The controller operates the brushless DC motor at multiple different speeds to accommodate multiple different thermal loads experienced by the refrigeration system. Each of the speeds corresponds to a different thermal load. The controller modulates the speed of the brushless DC motor to maintain a desired temperature of a temperature-controlled space within the temperature-controlled device.Type: ApplicationFiled: November 2, 2018Publication date: March 7, 2019Applicant: Hill Phoenix, Inc.Inventors: Jules G. Choueifati, Timothy D. Swofford, Neil J. Rathje

Publication number: 20190072311Abstract: Disclosed is a defrost system (200) comprising a refrigeration cycle (202) and defrost cycle (204), and a first heat exchanger (206) and a second heat exchanger (208). The first heat exchanger (206) exchanges heat between the defrost cycle (204) and a heat source (210) whereby the defrost fluid of the defrost cycle may undergo at least a partial phase change in the first heat exchanger. The second heat exchanger (208) exchanges heat between one or more components of the refrigeration cycle (202) and the defrost cycle (204).Type: ApplicationFiled: March 24, 2017Publication date: March 7, 2019Applicant: SCANTEC REFRIGERATION TECHNOLOGIES PTY.

Publication number: 20190072313Abstract: The present disclosure relates to an insulated door having two horizontal rails and two vertical rails. Each of the two horizontal rails is in contact at its two extremities with extremities of the two vertical rails. Each rail comprises an elongate interior side piece, an elongate exterior side piece, an elongate cover adapted to be mounted to the interior side piece, and an elongate rail insulation element linking the interior side piece to the exterior side piece. The rail insulation element prevents any direct physical contact between the interior and exterior side pieces. The door also comprises a sealed glass unit enclosed in a perimeter formed by the rails, an outside face of the sealed glass unit being in contact the exterior side pieces, an inside face of the sealed glass unit being in contact with the covers. A refrigerator door system incorporating the insulated door is also disclosed.Type: ApplicationFiled: November 2, 2018Publication date: March 7, 2019Inventors: Mathieu GRENIER, Vincent CORMIER
