摘要：

A simple technique for refrigerant mass measurement is described and evaluated. First, quick-closing valves trap the refrigerant in the section under consideration. Then, the refrigerant is expanded into a tank, thus reaching a superheated state. Finally the mass is calculated by p-nu-T relationship. The technique was implemented on a domestic refrigerator and was computer automated (no need for manual intervention). Preliminary (1) data are reported of the charge distribution during an on-off cycle. (C) 2004 Elsevier Ltd. All rights reserved.
