Patent number: 11982480Abstract: A refrigeration system includes a high-pressure side with a gas cooler configured, while the refrigeration system is powered by a main power supply and is operating to provide refrigeration, to cool refrigerant on the high-pressure side. The refrigeration system includes a low-pressure side with one or more evaporators. The refrigeration system includes an auxiliary compressor coupled to a backup power supply. An input of the auxiliary compressor is coupled to fluid conduit of the low-pressure side, and an output of the auxiliary compressor is coupled to fluid conduit of the high-pressure side. A controller is communicatively coupled to the auxiliary compressor. After determining that the main power supply is unavailable, the controller causes the auxiliary compressor to turn on to move refrigerant from the low-pressure side to the high-pressure side.Type: GrantFiled: August 9, 2022Date of Patent: May 14, 2024Assignee: Heatcraft Refrigeration Products LLCInventors: Douglas Cole, Steve Pfister

Publication number: 20240093921Abstract: A cooling system partially floods the low temperature low side heat exchangers (e.g., freezers) in the system. An accumulator is positioned between the low temperature low side heat exchangers and the low temperature compressor. The accumulator collects the refrigerant (both liquid and vapor) from the flooded low temperature low side heat exchangers. Refrigerant discharged by the low temperature compressor is fed through the accumulator so that heat can be transferred to the refrigerant collected in the accumulator. As a result, the temperature of the refrigerant discharged by the low temperature compressor drops before that refrigerant reaches the medium temperature compressor.Type: ApplicationFiled: December 1, 2023Publication date: March 21, 2024Inventors: Shitong Zha, Douglas Cole

Patent number: 11353245Abstract: A cooling system is designed to operate in two different modes. Generally, in the first mode, when parallel compression is needed, certain valves are controlled to direct gaseous refrigerant from a tank to a compressor in the system and to direct refrigerant from low side heat exchangers towards other compressors. In this manner, a compressor in the system is transitioned to be generally a parallel compressor. In the second mode, when parallel compression is not needed, the valves are controlled to return the refrigerant flow back to normal.Type: GrantFiled: January 3, 2020Date of Patent: June 7, 2022Assignee: Heatcraft Refrigeration Products LLCInventor: Douglas Cole

Publication number: 20160372618Abstract: A solar cell strip assembly includes an adhesive bearing polymer sheet, solar cell strips, and reflective strips to form a stable package suitable for substitution for conventional solar cells in solar module manufacturing. The solar cell strip assembly increases the mechanical stability of narrow width cells to reduce breakage during handling and improved electrical integration options. The addition of reflector strips provides a convenient means for delivering additional functionality into the module such as concentration. Solar modules are commonly fabricated from whole or fractional silicon wafer solar cells which are series connected into strings and incorporated into a sealed module package with glass and EVA using thermal vacuum lamination.Type: ApplicationFiled: June 14, 2016Publication date: December 22, 2016Inventor: Eric Douglas Cole
