Patent number: 10718551Abstract: A hybrid Vapor Compression (VC) and Thermoelectric (TE) heat transport system is provided that maintains a set point temperature range of a chamber and includes a VC system and a TE system. The VC system includes a compressor, a condenser-evaporator connected to the compressor, a first valve connecting the compressor to an evaporator-condenser, and a second valve connecting the evaporator-condenser to a thermal expansion valve. The TE system includes TE modules, a first heat exchanger thermally connected with a first side of the TE modules which connects the first valve and the second valve, and a second heat exchanger thermally connected with a second side of the TE modules which connects the first valve and the second valve. In this way, the VC system and the TE system can be operated individually, in series, or in parallel to increase the efficiency of the hybrid VC and TE heat transport system.Type: GrantFiled: October 14, 2016Date of Patent: July 21, 2020Assignee: Phononic, Inc.Inventors: Jesse W.

Patent number: 9746247Abstract: The present disclosure relates to systems, devices, and methods that augment a thermosiphon system with a thermally conductive matrix material to increase the surface area to volume ratio for heat conduction at a predetermined region(s) of the thermosiphon system while minimizing capillary forces that are isolated to those region(s). The thermosiphon system has tubing including a condenser region, an evaporator region, and an adiabatic region (e.g., a region between the condenser and evaporator regions). The tubing can contain a heat transport medium and can provide passive two-phase transport of the heat transport medium between the condenser and evaporator regions according to thermosiphon principles. The system also includes a thermally conductive matrix material contained in the condenser region and/or the evaporator region but not in the adiabatic region, such that the thermally conductive matrix material increases a surface area for heat transfer in the condenser region and/or the evaporator region.Type: GrantFiled: January 30, 2015Date of Patent: August 29, 2017Assignee: Phononic Devices, Inc.Inventors: Jesse W. Edwards, Robert B. Allen, Daniel Swann

Patent number: 6438973Abstract: Electronic circuitry provides protection for refrigeration machines by continuously monitoring supply voltage conditions and various other conditions. Information regarding abnormalities detected in the refrigeration machines or supply voltage is stored in a memory. The stored information may then be downloaded from the memory by a service technician. The electronic circuitry is universal and can therefore be used with various refrigeration machines. Further, the efficiency of a low temperature storage cabinet is enhanced by cycling the evaporator motor in comparison to a compressor percentage run time. Other factors are also considered in the running of the reach-in cabinet evaporator fan.Type: GrantFiled: May 1, 2000Date of Patent: August 27, 2002Assignee: Hoshizaki America, Inc.Inventors: Kazuhiro Yoshida, Donald Dunn, Robert McDonald, William P.
