Résumé

This article presents the numerical model of a heat pump using CO2 in a transcritical cycle. Two systems are envisaged in this work: a heat pump for simultaneous heating, cooling and domestic hot water (HPS1) and a heat pump for simultaneous cooling and desalination (using heat) (HPS2). The simulation study uses EES and TRNSYS to assess the performance of two heat pumps in different applications and operating conditions. The simulations show interesting performance indicators: the seasonal COP for heating and cooling and the exergy efficiency for both systems. HPS2 producing cooling and desalination has a higher seasonal process exergy efficiency than HPS1 due to the interesting use of energy for the desalination application. The performance analysis presents a seasonal Coefficient of Performance (COP) between 2 and 3.
