Mesures in situ de la composition des mélanges de frigorigènes zéotropiques dans les systèmes frigorifiques et à pompe à chaleur.

In-situ measurement of circulated composition in refrigeration and heat pump systems using zeotropic refrigerant mixtures.

Auteurs : JOHANSSON A., LUNDQVIST P.

Résumé

Some refrigerant mixtures are zeotropic, e.g. R407C and Isceon 59. The circulated composition may change from the nominal to a different composition. The changes are due to leakage or hold-ups of liquid or vapour phase, different solubility in the oil by the different components, or the fact that the system has been charged in an incorrect way. When performance measurements are made on systems, it is often important to know the exact composition of the circulated refrigerant. A measuring method has been applied and evaluated on a well equipped lab rig at the Department of Energy Technology at the Royal Institute of Technology.
