Impact of uncertainties on estimations of heat pump cycle performance.

Author(s) : HOGBERG M., VAMLING L.

Type of article: Article, IJR article

Summary

Sensitivity analysis is used to show how uncertainties in basic factors, such as heat transfer, pressure drop, compressor efficiency, and thermophysical properties, influence the result of heat pump cycle performance estimations. Working fluids, both pure substances and non-azeotropic mixtures, were examined. It was found that evaporation heat transfer and compressor efficiency are two areas where improvements are needed. It is also shown that estimates using very accurate, substance-specific, equations of state differ from those using more general types by up to 1% for COP and 2% for capacity.
