Title: Compressor-simulation model with corrections for the level of suction gas superheat
Abstract: A compressor simulation model, based on empirical performance curves from reciprocating compressor manufacturers, is discussed. The compressor model is part of a heat pump simulation model being developed for potential use in reducing the amount of testing required for air-to-air heat pumps by the new rating procedures being implemented by DOE. Corrections to the compressor performance curves (maps) are developed to account for the effect of different superheat (or quality) levels on refrigerant mass flow rate and compressor power; the corrections are in general agreement with the average of the available information from manufacturers of two- to four-ton, R-22, hermetic, reciprocating compressors. Comparisons are made between the compressor model predictions and available data from four heat pump experiments. The comparisons indicate that more experimental data are needed at the lower ambient conditions in the heating mode under conditions of wet suction gas and with lower air temperatures over the compressor shell.
