Abstract :
[en] This paper presents an experimental analysis of the intermediate conditions for a variable speed (VS) vapor-injection scroll compressor (SCVI) under several working conditions and speeds. A set of experimental tests was conducted for a VS-SCVI working with R-410A as a refrigerant. From the experimental data and based on previous correlations obtained for constant speed SCVI, a correlation for VS-SCVI was obtained to estimate the injection ratio depending on the compressor speed with an error lower than 10%. Results showed differences in the intermediate conditions of the compressor for low and high compressor speeds.
