Abstract

The invention relates to a device which is used to determine and/or control the necessary and sufficient quantity of refrigerant for an air-conditioning system. The inventive device comprises: a portable case (4) housing (i) a memory element (5) containing pre-recorded pressure and temperature values and (ii) data analysis and calculation means (6); at least three temperature sensors (C1, C2, C3) and at least one pressure sensor (C4), all of which are functionally connected to the aforementioned analysis and calculation means (6); and a display element (7) which is controlled by said analysis and calculation means (6). The invention also relates to the air-conditioning system.
