Patent number: 8887516Abstract: A refrigerant charging system and method for charging a refrigeration system with a vapor-phase refrigerant includes a refrigerant source, an input line, a sensor and a pressure regulator. The input line connects the refrigerant source to the refrigeration system. One or more valves are disposed between the refrigerant source and refrigeration system to regulate the pressure of the refrigerant being introduced into the refrigeration system, and the sensor measures the pressure of the refrigerant entering the refrigeration system. A pressure regulator can also be used to regulate the flow of refrigerant. Once the pressure of the refrigerant reaches a predetermined pressure, the refrigeration system is fully charged, and the transfer of refrigerant to the refrigeration system is stopped. The system and method are used to charge the refrigeration system of, e.g., an automotive vehicle, and the refrigeration is carbon dioxide.Type: GrantFiled: July 23, 2010Date of Patent: November 18, 2014Assignee: Bosch Automotive Service Solutions LLCInventors: Craig F. Govekar, Dean P. Pfefferle, Larry G. Moller, Anwar Suharno, Ken R. Meldahl

Patent number: 8434523Abstract: An upgradeable A/C maintenance system and methodology is provided including one or more modular manifolds for mounting and fluidly connecting several components. Embodiments include first and second manifolds, each for removably mounting a plurality of components, and each comprising an internal passage for fluidly connecting at least two of the plurality of components to each other, and a port for fluidly connecting the internal passage to an external surface of the first manifold. The first and second manifolds are removably attachable to each other such that their respective ports fluidly communicate with each other. The first manifold provides a first functionality for the system when the second manifold is not attached to the first manifold, and the second manifold provides a second functionality different from the first functionality when the second manifold is attached to the first manifold.Type: GrantFiled: October 29, 2010Date of Patent: May 7, 2013Assignee: Service Solutions U.S. LLCInventor: Anwar Suharno

Patent number: 7254954Abstract: A refrigerant charging system and method for charging a refrigeration system with refrigerant includes a refrigerant source, one or more cartridges, an input line, an output line, and a scale preferably having an accuracy within about ±0.2 ounce. The cartridge is filled with refrigerant by transferring the refrigerant from the refrigerant source to the cartridge, after which, the filled cartridge is disconnected from the refrigerant source. An initial weight of the filled cartridge is obtained, and the cartridge is connected to the refrigeration system. Refrigerant is then transferred from the filled cartridge to the refrigeration system. A revised weight of the filled cartridge is obtained, and the revised weight is compared to the initial weight to determine if the refrigeration system has been completely charged. The cartridge is disconnected from the refrigeration system after the refrigeration system has been completely charged.Type: GrantFiled: April 25, 2005Date of Patent: August 14, 2007Assignee: Snap-On IncorporatedInventors: Craig F.
