An ornamental jewelry kit comprising at least one inner flat base element, a plurality of outer visible elements, wherein the plurality of outer visible elements are comprised of visible elements differing from other visible elements by at least one of color, material and shape, cooperating connection means comprising parts on the flat base element and parts on the visible elements for connecting the base and visible elements together, the cooperating means including at least two partially covered tracks and at least two posts with enlarged heads with the posts insertable into the tracks, the partially covered tracks have an uncovered portion allowing an enlarged head of the posts to enter into the covered tracks, the partially covered track is formed with at least a first passageway portion and a second passageway portion angled to the first passageway, and wherein a selected outer visible element is connected to the base element by aligning the at least two posts with respective uncovered portions of the covered tracks with the outer visible element offset from the respective base element, inserting the posts into the tracks, moving the outer visible element relative to the respective base element to cause the posts to move along the first passageway portion and then along the second angled passageway to a position where the outer visible element covers the base element. rom at least one temperature sensor placed in thermal contact with the evaporator or downstream from it in the said airflow, and the signal value of said signal is compared with a reference value corresponding to a normal refrigerant-fluid level, a signal value below the reference value indicating a low refrigerant-fluid level, wherein said closed loop air-conditioning system includes a compressor of the variable-throughput type controlled by an electrical control signal, and wherein said reference value is calculated from said control signal. 8. A method according to claim 7, wherein the compressor is of the external-control, variable-displacement type including a valve, said control signal being a control current supplying said valve, said compressor including pressure determining means operable to establish, at the inlet to said compressor, a pressure which is determined by the said control current. 9. A method according to claim 7, wherein the compressor is driven electrically. 10. A method according to claim 7, wherein said representative signal value is derived when the compressor is operating at a sufficient throughput, in the case of a normal fill level, to provide correct filling of the evaporator with fluid in the liquid state. 11. A method according to claim 10, wherein when said compressor is operating, the airflow leaving the evaporator is reheated so as to be sent into the passenger compartment at the desired temperature. 12. A method according to claim 7, wherein said reference value corresponds to a temperature which is a few ° C. lower than a temperature varying as a control signal linear function, which corresponds to the average value of said representative signal in a normal charge case.
