Performance analysis of a single-stage scroll compressor used in a drying heat pump over a wide condensing temperature range (30–80°C)

This study presents the performance of a new single-stage scroll compressor used for the heat pump drying of thermally sensitive materials over a wide temperature range. The performance of the new compressor was predicted by an ARI standard 540 map-based compressor model and verified by a semi-open drying heat pump system constructed for this purpose. A comparison of the experimental data with the predicted data proved that the new scroll compressor used in the drying heat pump works well, can supply a wide range of condensing temperatures (30–80°C) (without auxiliary heating), and has a minimum coefficient of performance (COP) above 2.0, even in the worst condition.
