Title: Viraj Vartak: Automotive Refrigeration Innovation
Introduction
Viraj Vartak is an inventor associated with Ferndale, Michigan, and General Motors Global Technology Operations, Inc. His patent work addresses refrigerant-system design for vehicles, including vapor injection and hot-gas bypass.
Latest Patents
Vartak is named on one patent, titled “Vehicle Refrigerant System Using Hot Gas Bypass with Vapor Injection.” The invention describes a vapor-injection refrigerant system with a compressor, condenser, evaporator, and chiller. The compressor has first- and second-stage inputs, and the chiller can inject refrigerant vapor into either input. A bypass branch routes some compressor output directly to the first-stage input, avoiding the condenser, evaporator, and chiller. This arrangement provides an alternative refrigerant flow path within the system.
