Abstract
A heating, ventilation, air conditioning, and refrigeration (HVACR) system is disclosed. The HVACR system includes a compressor, a condenser, and an evaporator fluidly connected to form a refrigerant circuit. A lubricant return line is fluidly connected to the compressor and to the evaporator. A pressure difference between the compressor and the evaporator induces a fluid flow of lubricant from the evaporator to the compressor.
