Patent number: 11885545Abstract: A dynamic receiver is included in parallel to an expander of a heating, ventilation, air conditioning, and refrigeration (HVACR) system. The dynamic receiver allows control of the refrigerant charge of the HVACR system to respond to different operating conditions. The dynamic receiver can be filled or emptied in response to the subcooling observed in the HVACR system compared to desired subcooling for various operating modes. The HVACR system can include a line directly conveying working fluid from compressor discharge to the dynamic receiver to allow emptying of the dynamic receiver to be assisted by injection of the compressor discharge.Type: GrantFiled: August 8, 2022Date of Patent: January 30, 2024Assignee: TRANE INTERNATIONAL INC.Inventors: Philippe Del Marcel Tisserand, Stephane David Koenigsecker, Yves Jacques Raimbault

Publication number: 20230332808Abstract: Systems and methods for controlled subcooling of working fluid in a heating, ventilation, air conditioning and refrigeration (HVACR) system through a suction line heat exchanger are disclosed. The suction line heat exchanger may receive a first fluid flow travelling to a suction of the compressor in the HVACR system and second flow of working fluid that is travelling from a heat exchanger receiving the discharge of the compressor to an expansion device. Superheating of the first working fluid may be determined based on temperature measurements prior to and following the suction line heat exchanger. The superheating may be used to control the quantity of the second flow of working fluid introduced into the suction line heat exchanger, for example to maintain superheat that is below a threshold value. These systems may include chillers and heat pump systems, and methods may be applied to chillers or heat pump systems.Type: ApplicationFiled: June 26, 2023Publication date: October 19, 2023Inventors: Yves Jacques Raimbault, Philippe Del Marcel Tisserand, Qingnan Huang, Marie Tallotte, Clément Reignier

Publication number: 20220349605Abstract: Chiller systems can include a controller that is configured to determine whether to restart the chiller in a rapid restart mode or a soft loading restart mode, and methods can include determining the mode for restarting the chiller. The soft loading restart mode controls the chiller to provide a comparatively gradual loading, to avoid overshooting a target temperature. The rapid restart mode more aggressively loads the chiller to return more rapidly to a particular load level. The determination of the restarting mode can be based on characteristics of the interruption of power to the chiller system. In chiller systems, the controller can receive power from an uninterruptable power source to maintain continuity of power. The logic used by the controller can be based on whether or not the controller shares continuity of power with other components of the chiller system.Type: ApplicationFiled: April 26, 2022Publication date: November 3, 2022Inventors: Raphael Gury, Lee L. Sibik, Philippe Del Marcel Tisserand

The dynamic receiver allows control of the refrigerant charge of the HVACR system to respond to different operating conditions. The dynamic receiver can be filled or emptied in response to the subcooling observed in the HVACR system compared to desired subcooling for various operating modes. The flow through an expander of the HVACR system can be controlled to account for the mass flow rate through an outlet valve of the dynamic receiver when the dynamic receiver is emptied, preventing or reducing instability or effects on system parameters such as the suction superheat.Type: ApplicationFiled: May 27, 2022Publication date: September 15, 2022Inventors: Yves Jacques Raimbault, Philippe Del Marcel Tisserand, Gabriel Mateos, Stephane David Koenigsecker
