Title: Innovations by Earl A Campaigne, Jr.
Introduction
Earl A Campaigne, Jr. is a notable inventor based in Waynesboro, VA (US). He has made significant contributions to the field of cooling technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest inventions is a high capacity chiller compressor. This high-efficiency, low-maintenance single-stage or multi-stage centrifugal compressor assembly is designed for large cooling installations. The cooling system provides direct, two-phase cooling of the rotor by combining gas refrigerant from the evaporator section with liquid refrigerant from the condenser section. This innovative approach affects a liquid/vapor refrigerant mixture, enhancing the overall efficiency of the system. Additionally, a noise suppression system is integrated by injecting liquid refrigerant spray at points between the impeller and the condenser section.
Another significant patent by Campaigne is also a high capacity chiller compressor, which emphasizes efficiency through a variable frequency drive (VFD) that drives a permanent magnet motor. This design matches compressor speed with compressor load, eliminating gearing losses through a direct drive impeller. The use of magnetic bearings reduces frictional losses, and the back-emf produced by the motor serves as an intermediate power source for the magnetic bearings in case of electrical power loss. The modular construction allows for easy upgrades, and the lightweight design reduces the weight to one-third or less of comparably powered conventional units.
