[en] A detailed scroll compressor simulation has been developed as described in a companion paper. In this work, the compressor simulation code is used to investigate vapor injection in scroll compressors for cold climate heat pumps. The required analysis is developed for vapor injection in scroll compressors with one or two injection lines. The improvement in heat pump efficiency at a -20 C evaporation temperature with one injection line is as much as 10% while with two injection lines the increase in efficiency can be as much as 16%
