Publication number: 20170191719Abstract: A refrigerant management system is interchangeably connectable to a plurality of refrigeration systems and can manage one or more connected refrigeration systems. The refrigerant management system includes a portable system housing for securing various components in a self-contained unit. The refrigerant management system includes a work panel that can be arranged on the top of the system housing. The work panel includes various operational efficiency improvement devices that allow a user to use, store and organize various movable items that would otherwise be carried separately from the refrigerant management system.Type: ApplicationFiled: January 6, 2016Publication date: July 6, 2017Inventors: RONALD A. PLASEK, KARL JOHNSON, PETER TRUITT

Patent number: 7428822Abstract: The compressor head, internal and/or external discriminator, and manifold design in general utilize ball valves on the suction and discharge of a cylinder head in the recovery of refrigerant liquid and/or vapor. The device facilitates the flashing of liquid refrigerant pumped to the compressor which, in turn, assists to cool the compressor head. The flashing of liquid refrigerant to vapor also deters liquid transfer into the compressor enhancing performance thereof. The vapor passages within the discriminator, cylinder head and/or manifold are sized for receipt of spring actuated ball's to open and/or close the vapor passages during suction and/or discharge of refrigerant vapor or liquid by the compressor.Type: GrantFiled: July 10, 2006Date of Patent: September 30, 2008Assignee: Ritchie Engineering Company, Inc.Inventors: Ajit Ramachandran, Keith Sliger, Ronald A.
